Answer:
The P site
Explanation:
The P site holds the tRNA with the growing polypeptide chain. The E site serves as a threshold. It holds the tRNA without its amino acid, which is then released by ribosome.
The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete
Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%

Do not compare the size and colour of the leaves.
Based on the diagrams shown above,
state one similarity between Leaf A and Leaf B.
Answer:
They both have a petiole
Explanation:
Leaf A and Leaf B both possess a petiole.
A petiole is the part of the leaf found beneath it which attached the leaf to a stem.
Observing both leaves, they both have this in common. Therefore, they are similar because they both have petiole.

how do you prove the fact that green plant releases Oxygen gas in the process of photosynthesis explain the experiment.
Answer:
Aim : To prove that oxygen is produced during photosynthesis
Procedure : Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.Invert the test tube full of water and cover the stem of the funnel.While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants

In an ad hominem persuasive technique a person is attacked rather than give an argument.
What is an ad hominem argument?
An ad hominem reasoning argument is a type of argumentation where its validity is not based on an attribute.
An ad hominem argument is fallacious because it does not involve verifiable information to be proved.
This type of argumentation occurs when one person is attacked based on feelings of prejudice and or fallacious commentaries.

Your mother asked you to put water soluble fertilizer around the roots of her prize winning rose bush. The following week, you noticed the leaves of her rose bush are beginning to turn yellow and wilt. In terms of tonicity and water movement, explain why the rose began to die after the addition of fertilizer. Bonus: What can you do to solve this problem
Answer/Explanation:
The water soluble fertilizer that was added created a hypertonic environment. Concentration of solute is higher around the plant cells thereby leading to the movement of water molecule away from the cells of the rose bush. This is why the rise bush began to wilt as the leaves turn yellow.
Solution:
Give the plants a reasonable amount of water to cause the solution to be isotonic. When the amount of fertilizer and water is relatively balanced, the plants would be able to utilize the fertilizer, feed well and grow well.

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.

Which pattern of inheritance does nose size follow?
complete dominance
codominance
incomplete dominance
sex-linked dominance
Answer:
incomplete dominance
Explanation:
This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.
