Answer:
Option-C
Explanation:
The flow of nutrients from the sewage and industries is the cause of the nutrient pollution in water bodies. These chemicals get accumulated in the water bodies affecting the aquatic ecosystem to a very large extent.
The increased level of nitrogen and phosphorus causes eutrophication which is also known as algal-boom. These nutrients cause the massive growth of algae which decreases the oxygen level of the water bodies. This increases BOD level of the water bodies which does not allow the growth of other aquatic species.
As a result of this, the dead zones are created where nothing can survive and therefore is the correct answer.
Thus, Option-C is the correct answer.

If parents supplied different alleles for a certain trait to their offsprings, which of the following terms would be used to describe the offsprings?
Answer:
Heterozygous
Explanation:
Heterozygous is when there is two of the different alleles or genes that will make up their offsprings, and Homozygous is when there is two of the same alleles or genes
It was believed for a long time that Jellyfish were a trophic “dead end” and that no organisms utilized jellyfish as a food source. Based on the illustration above, is it true that Jelly fish are at the top of the food chain? Explain your reasoning using the data.
In the Irish sea, a lot of different types of water animals eat jellyfish. It would be hard to say that they are on the top when all these animals/fish eat the jellyfish. Out of 2500 examples of different species the herring had more than 20 percent of jellyfish in them out of 512 that were cut open to see if a jellyfish was in them. In this whole experiment 2500 sea creatures were gutted and the results definitely weren't in the jellyfishes favor. Although the Grey Gurnard, Dab, Sprat, Poor Cod and Squid do not eat much Jelly Fish. The Herring and Dragonet do. I def finitely do not think they are on the top, but they sure do not have that many sea creatures eating them. And you would of thought that the ones that did would be bigger. I am actually very surprised to see that so many creatures were found with the Jelly Fish inside of them. I also wonder what other creatures eat it that we may not know about yet.

Answer:
The algae are producers.
The snails are primary consumers.
Herons is a secondary consumer.
Explanation:
Food web is the interconnection of different food chains in the ecosystem and it represent the different feeding relationships between organism in the ecosystem.
From the question,
Algae is a primary producer because it has the ability to produce food.
Algae have chlorophyii, a green pigment which trap light energy from the sun and uses carbondioxide and water to produce food which other organism depend on.
Snail is a primary consumer because it's depend on algae for food. Snails feed on algae because they cannot produce their own food.
Heron is a secondary consumer because it feed on snails. They feed directly in snails to obtain their energy requirement for survival.

5. Does a woman have periods while she is pregnant?
Answer:
No
Explanation:
A period is when your body produces a layer of tissue and blood to protect the baby. But the period is when your body is like "oops, false alarm" and disposes of the tissue and blood. During pregnancy, the baby is kept safe by the tissue and blood, that is why women don't have periods during pregnancy.

The oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is an endergonic reaction, but the flow through this point in glycolysis proceeds smoothly. Part A How is the unfavorable equilibrium constant overcome
Answer:
This inbalance is constantly overcome by the production of excess product (1,3-bisphosphoglycerate) which triggers the reversible reaction through the action of the enzyme called glyceraldehyde 3-phosphate dehydrogenase in the process called gluconeogenesis .
Explanation:
A cofactor (NAD+) and a phosphate molecule are crucial to this reaction to produce NADH which results in ATP a high energy molecule. an OH ion is removed from the glyceraldehyde-3-phosphate molecule and transferred to the NAD to form NADH molecule and an intermediate (thioester). The Phosphate molecule then binds to the thioester to form 1,3-bisphosphoglycerate
1. The length of a dog's tail is an inherited trait. The allele for short tails is dominant (T) over the
allele for long tails (t). A dog breeder mates two short-tailed dogs (parents). One parent is
homozygous and the other is heterozygous for this trait (10 points).
a. Complete the Punnett square for the genetic cross described above:
Answer/Explanation:
Given==> short tail allele (T) is dominant, and long tail allele (t) is recessive.
Genotype of homozygous short-tailed dog = TT, while genotype of heterozygous short-tailed dog = TT
Required==> Punnett Square showing a genetic cross between both parents: i.e. TT X Tt
*See attached image for the Punnett Square
From the Punnett Square, 50% of the offspring of the First generation would be homozygous short-tailed, while 50% would be heterozygous short-tailed.
All the offspring would be all short-tailed as well.

Suppose that a population composed of 100 individuals existed on an island in the Caribbean Sea. Two different alleles of the A gene were present in this population ( a1 and a2 ) at equal frequency. The following events occurred to this unlucky population. Determine what evolutionary force (mutation, migration, drift, or selection) is represented by each event. In addition, tell the effect of each eventon the genetic composition of the population.A) A devastating fire caused the death of 10 individuals.
B) A disease swept through the island and killed 13 individuals. The a1 confers resistance to the disease.
C) A disease swept through the island killing 13 individuals. Neither a1 nor a2 confers resistance to the disease.
D) A boat containing individuals from a different island containing a1, a2, and a3 alleles landed at the island.
E)The leader (whose genotype is a1a1) declared that only individuals with the a1 have the right to be on the island and mate. All a2, a3 individuals moved to another island.
F) A man stumbles upon a barrel that has spilled its contents on some rocks. Unknown the to man, who cannot read, the barrel says "Radioactive". He decides to bring one of the new glowing rocks home to show his wife and puts it in his pants pocket.Some of their babies had an a4.
Answer:
Explanation:
D) A boat containing individuals from a different island containing a1, a2, and a3 alleles landed at the island.
This is an example of migration. It is the movement of an organisms into a particular place or habitat. It increase the population of its new environment and decrease the population of the environment it migrated from.
E)The leader (whose genotype is a1a1) declared that only individuals with the a1 have the right to be on the island and mate. All a2, a3 individuals moved to another island.
This is example of selection. Selection is done in a large population to select traits with desired characteristics. Selection helps to have individual with the best features.
F) A man stumbles upon a barrel that has spilled its contents on some rocks. Unknown the to man, who cannot read, the barrel says "Radioactive". He decides to bring one of the new glowing rocks home to show his wife and puts it in his pants pocket.Some of their babies had an a4.
This is an example of mutation. It a sudden heritable change in the genome of an organism. it can be caused by exposure to radioactive material. Mutation can have a detrimental effect on individual carrying it or useful.
A) A devastating fire caused the death of 10 individuals
Drift- Genetic drift leads to the loss of genotype that are less frequently perpetuated or less occuring and are selected against.
B) A disease swept through the island and killed 13 individuals. The a1 confers resistance to the disease.
Selection- they have selective advantage of been resistance to disease.
Joe is trying to find out how solar energy can replace the functioning of certain individual needs. With this research, which phenomenon is Joe trying to curb?
a. Global warming
b. Acid rain
c. Increase in sea levels
Answer:
a. Global warming
Explanation:
Solar energy is the form energy which uses the SUN as Its source. It is a renewable source of energy. Humans, through our activities, contribute to the gradual increase of the earth's atmospheric temperature, called GLOBAL WARMING. We contribute to this phenomenon posing threat to the environment's sustainability when trying to fulfil our day-to-day individual needs.
One of those activities is the burning of fossil fuels via cars, in industries, domestic households etc. The burning of fossil fuels results in the release of heat-trapping gases called Greenhouse gases e.g CO2, CFC etc. These gases are the major cause of Global warming.
Hence, Joe is trying to work on how solar energy can replace the use of other sources of energy that release these greenhouse gases into the atmosphere in order to curb GLOBAL WARMING.
N.B: Solar energy does not emit greenhouse emissions. It is the best and safest source of energy.
What is needed in order for plants to take up nutrients from the soil?
Answer:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.

If the interference value is 1, then what is the probability of recombination between genes A and B if: 1.There is a recombination between genes B and C, where the gene order is A-B-C; 2.The recombination fraction between A and B is 0.05; 3.The recombination fraction between B and C is 0.45?
A. 0.45.
B. 0.05.
C. 1.00.
D. 0.15.
E. 0.0.
Answer:
E. 0.0.
Explanation:
The measure of crossing over coincidence interrelatedness between one cross over and another in a given pair of chromosome is known as what is called Interference.
Given that :
the interference value = 1
The probability of recombination between genes A and B is zero i.e 0.0 because:
when another gene co-occur with a particular gene during cross over, the coefficient of coincidence decreases. We know that the interference is maximum at 1, we can say it ranges from 0-1; now that two recombination is taking place in two genes,the probability is likely to decrease from 1 to 0.0
Similarly; Since the probability of recombination is taking place between two genes i.e genes A and B. Then there is no probability of double crossover when interference value = 1 but when it is zero there is probability of double crossover to occur. With that being said, the probability of recombination between genes A and B is 0.0

if Tyler does not eat a diet that includes essential amino acids his cells will not be able to build
Answer:
Protein is an essential ingredient of every cell in the body. Hair and nails are often made of protein. Your body uses protein to strengthen and repair muscles. You also use protein to make catalysts, hormones, and other body chemicals. Protein is an essential building mass of bones, muscles, cartilage, skin, and blood.
Pls mark me brainliest
Answer:
Proteins
Explanation:
Amino acids are the building blocks, or the monomers of proteins. There are 20 types of amino acids that build protein in our bodies. If Tyler’s diet does not include amino acids, then his body and his cells cannot make proteins.
This is not good for his body, because protein is very important. Protein is part of many different body parts. It is also used for growth and repair. Additionally, protein is used in the creation of enzymes and hormones.
Therefore, the answer is protein. If Tyler’s diet lacks amino acids, he cannot make proteins.

how lysosomes may be involved in the removal of the interdigital membrane of the developing mammalian fetus.
Answer:
Lysosomes are organelles that contain hydrolytic enzymes (lysozymes) which are required for membrane degradation, thereby they may be important during the removal of the interdigital membrane.
Explanation:
Lysosome plays a critical function by digesting cellular components such as, in this case, the interdigital membrane. During mammal embryo development, the interdigital membrane is reabsorbed, it is a structure between the digits that appeared during evolution in aquatic animals. However, in terrestrial mammals, it is a vestigial structure leftover from their ancestors.
Explain the relationship between mutations, adaptations,
natural selection, and extinction.
Answer:
Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.

In response to electrical stimulation of a particular brain region, a rat shows increased blood pressure and heart rate, dilation of the pupils, erection of the hair on the back, arching of the back, and biting at the air. Which region could the electrode be stimulating
Answer:
The brain stem is responsible for increased blood pressure, HR etc,
Explanation:
It is made up of the mid brain, the Pons, and the Medulla.
While the Pons serve as the neurological bridge between the brain regions e.g the cerebrum and cerebellum to conduct and control certain responses the Medulla controls involuntary activities.Thus the involuntary activities listed above are controlled by the medulla.
Thus the activities of the rats which involves the dilation of pupils, erection of hair, are controlled in the pons. While increases blood pressure and the H.R are under the medulla.
