Answer:
Explanation:
The mutation was caused as a result of deletion of one letter of the codon A from tyrosine leading a shift in the reading frame.
Normal is
Normal - Met - Tyr -His- Glu- Val
Aug- Uac- Cac - Gaa -Gug
When a is removed from Tyrosine codon we have a shift in the reading frame to form a mutant with a new codon and protein.
Mutant - Met- Phe - Thr - Lys -Cys
Aug- Ucc- Acg - Aag -Ugu
Mutation is a sudden change in the genie of an organism that can be heritage by offspring from their parent.
Why do most multicellular organisms require more than just diffusion to facilitate gas exchange? What is the other process called? Name all the places in our body where these two different processes occur (i.e. where do we get diffusion and where do we get the other process).
Answer:
The description including its problem is described throughout the segment below on explanation.
Explanation:
Surface layer influences combustion efficiency, the larger the surface region, the more and more fuel traded. Hence, gills as well as lungs become established in the organism's purpose of providing an enormous surface area for both the necessary currency value of gas towards the outer atmosphere.
The ranges among gas exchanger as well as shallow tissues become ideal through dissemination to fulfill the necessity so a range of respiratory substances is required. Respiratory interfaces are coated with epithelial cells to allow exchanging of gases.The oxygen through both the respiratory system would be transferred into the bloodstream, as well as the RBC collect the CO2 from the cells it to the lungs for oxygenation. Exterior ventilation, oxygen absorption from capillaries to CO2 absorption from capillary to alveoli. Inner ventilation happens at the surface including its body cells.is the vaccine effective ?

he Punnett square shows the cross for a particular trait between a homozygous dominant parent and a heterozygous parent. What is the probability the offspring will be heterozygous for this trait? 25% 50% 75% 100%
Answer:
50%
Explanation:
Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.
One homozygous dominant parent = XX
One heterozygous parent = Xx
X X
X XX XX
x Xx Xx
So two out of our four outcomes are heterozygous for the trait. That means the answer is B. 50%.
The probability the offspring will be heterozygous for this trait is 50%
What are the features of heterozygous traits?Heterozygous is the presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.
To be heterozygous for a trait is to have different alleles for it. Being homozygous for a trait means that it will always turn out the same.

Under certain circumstances, potassium ions ( K+K+ ) in a cell will move across the cell membrane from the inside to the outside. The potential inside the cell is −70.5 mV−70.5 mV and the potential outside the cell is zero. What is the change in the electrical potential energy of a single potassium ion as it moves across the membrane?
Answer:
the change in the electrical potential energy of a single potassium ion as it moves across the membrane is 1.12941 × 10⁻²⁰ J
Explanation:
The formula used in determining the change in the electrical potential energy can be expressed by the relation.
Charge in electrical Potential energy = [tex]q ( V_2 - V_1)[/tex]
where q = the potassium ion
q = 18 electrons and 19 protons
q = 19-18 = 1 electron
1 electron = 1.602 × 10⁻¹⁹ Coulombs
Thus;
the potential inside the cell is −70.5 mV
= -70.5 × 10⁻³ V
∴ Charge in electrical Potential energy = [tex]q ( V_2 - V_1)[/tex]
Charge in electrical Potential energy = [tex]1.602*10^{-19} ( 0 - (-70.5*10^{-3})[/tex]
Charge in electrical Potential energy = 1.12941 × 10⁻²⁰ J
Thus; the change in the electrical potential energy of a single potassium ion as it moves across the membrane is 1.12941 × 10⁻²⁰ J

There is a large tree growing in the middle of the lawn. You notice that there are lots of daisies in the lawn, but none under the tree. Suggest two hypotheses to explain why there are no daisies under the tree. Choose one of your hypotheses and make a prediction from it which can be tested by an experiment. Describe an experiment which could be done to find out if the prediction is correct.
Answer and Explanation:
Hypothesis:
1- No daisies can grow under the tree because its canopy does not allow enough radiation to reach the ground under it.
2- No daisies can grow under the tree because it changes the soil composition and pH.
Prediction:
Daisies grow better and faster when they are completely exposed to solar radiation.
Experiment:
30 daises young plants, grown under the same conditions, will be planted in three different parcels. Planting will take place during spring.The three parcels will have the same soil, with all the nutritional requirements that daisies need to grow properly. The three parcels will be watered every day to keep equal humidity conditions. The variable under study is the radiation, so this is the only factor that will differ between parcels. One of the parcels will be completely exposed to solar radiation. A second parcel will receive sunlight during half of the day, while the other half of the day will be under the shadow. The third parcel will be completely under the shadow (no radiation will reach this parcel). Daisies will be grown for four months. Every fifteen days all the plants will be counted in each parcel to check their survival. Their length will be measured, and the presence of new leaves, floral buttons, and ramifications will be registered. The size of the leaves and flowers will also be registered. After four months, data will be analyzed to evaluate how does the radiation influence the plants' growth.In laborador retrievers, pigment color is influenced by two genes.

Fungi are important decomposers in terrestrial ecosystems. Some fungi are able to break down lignin in plants, through the production of an enzyme called lignin peroxidase, something that no other organism can do. The ability to break down lignin by some fungi is reflected by which of the statements?
A. Expression of genes necessary to break down lignin were lost in lineages that are not in the evolutionary history of fungi.
B. A mutation occurred in a gene found in some fungi, and the enzyme produced is able to break down lignin.
C. Many organisms have the end to producentymes for breaking down lignin but do not express those genes
Answer:
The correct answer is option B. "A mutation occurred in a gene found in some fungi, and the enzyme produced is able to break down lignin".
Explanation:
The unique trait of expressing lignin peroxidase that some fungi have in order to break down lignin must have being the result of natural selection. Natural selection works under the premise of "survival of the fittest", where a spontaneous mutation gives an advantageous trait to an individual that makes it more likely to survive and reproduce. In this case breaking down lignin gives some fungi the advantage of being able to feed from wood.

The resource competition model of sympatric speciation requires: A. divergent/disruptive selection driving character displacement. B. directional selection driving character displacement. C. evolution of reproductive isolation D. Both A & C E. Both B & C
Answer:
The correct answer is option D, that is, both disruptive selection and evolution of reproductive isolation.
Explanation:
The phenomenon of the evolution of a novel species from a thriving ancestral species and at the same time both continue to live in a similar geographical area is termed as sympatric speciation. Due to reproductive isolation of the population of species that were thriving in a similar habitat, the phenomenon of sympatric speciation results.
On the other hand, sympatric speciation also results due to disruptive selection as in the process the extreme kind of individuals within the population are favored over the hybrids.

Answer:
Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
The process occurs during the light dependent reactions in photosynthesis is "Split water molecule occurs."
What is photosynthesis?Plants utilize sunlight, water, as well as carbon dioxide to produce oxygen or energy in the type of sugar in a process known as photosynthesis.
What is light dependent reactions?
The thylakoid membranes are the site of light-dependent reactions. The light-independent reactions happen in the stroma, which is located outside the thylakoid membrane, and thus the lumen, which is located inside.
The power storage molecule ATP and even the reduced electron transporter NADPH are produced by the light-dependent processes using light energy, which is required for the subsequent stage of photosynthesis. Light reactions in plants occur in the thylakoid membranes of organelles referred to as chloroplasts.

A. Adaptation principle
B. Competitive exclusion principle
C. Predator-prey relationship
D. Niche principle
The correct answer is C. Predator-prey relationship
Explanation:
In a prey-predator relationship, one organism which is the predator feeds on another animal known as the prey. Additionally, predators hunt and kill their prey, which is essential for predators to obtain nutrients and survive. Besides this, predators can hunt and feed on only one type of animal or hunt and feed on different types of animals. This relationship occurs between the jaguar and the turtle because the jaguar hunts, kills, and eats the turtles, which means jaguars hunt and kill other animals to get nutrients. Also, in the case of the jaguar, this hunts different animals including fish, tapirs, turtles, and small mammals.

A farmer is raising rabbits. The average body weight in his population is 3kg. The farmer selects the 10 largest rabbits in the population, whose average body weight is 4kg, and interbreeds them. If the heritability of body weight in the rabbit population is 0.7, what is the expected body weight among the offspring of the selected rabbits?
Answer:
The expected weight increase that is expected of offspring of selected parents is 0.7 kg
Explanation:
Given from the question:
The average body weight in his population of rabbits = 3 kg
heritability of body weight in the rabbit population (h^2)=0.7
Average body weight of the 10 selected largest rabbit =4 kg
(R) = response to selection
selection differential (S)= Average body weight of the 10 selected largest rabbit - The average body weight in his population of rabbits
selection differential (S)= 4-3=1 kg
But heritability of body weight in the rabbit population (h^2)=0.7
Then, Heritability of body weight in the rabbit population (h^2) can be calculated using the formula below;
Heritability of body weight in the rabbit population (h^2)=
response to selection (R) / selection differential (S)
response to selection (R) = Heritability of body weight in the rabbit population (h^2) × selection differential (S)
R= h^2 x S= 0.7 x 1kg= 0.7 kg
The expected weight increase that is expected of offspring of selected parents is 0.7 kg
Average weight of offspring = The average body weight in his population of rabbits + heritability of body weight in the rabbit population (h^2)
Average weight of offspring= 3 kg + 0.7 kg = 3.7kg
Therefore, the Average weight of offspring is 3.7kg and The expected weight increase that is expected of offspring of selected parents is 0.7 kg
