Answer:The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood
Basically, the FSL states that the greater the stroke volume of the left ventricle will increase, as the volume of the the ventricles increases due to ventricular contraction, leading to systolic contraction.
If the volume of the blood in the Ventricle is increased, the blood volume stretches the ventricular walls and the ventricle contracts.The amount of blood ejected from the ventricle increased(stoke volume).Therefore, the higher the contraction of the ventricles, Myocyte stretch, the more the volume of blood in the ventricle pushed, and the more the amount of the blood ejected from the ventricle as Stroke Volume.

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.
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

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.

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.

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

What is the purpose of a Punnett square?
Answer:
A Punnett square is a diagram used to determine the statistical likelihood of each possible genotype of the offspring of two parents for a given trait or traits. Reginald Punnett was applying the laws of probability to work pioneered by Gregor Mendel in the mid-1800s.
hope that helps love!
Answer:
The Punnett square is a square diagram that is used to foretell the genotypes of a particular cross or breeding experiment. The diagram is used by biologists to determine the possibility of an offspring having a precise genotype.
Explanation:
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
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.

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.

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.

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.
