Question 1 A heterozygous yellow-seeded plant is crossed with a homozygous yellow seeded plant. i. ii. Question 2 Complete the punnet square and write the genotypic and phenotypic ration for the possible offsprings. (3 marks) Genotypic ration Phenotypic ration What is the probability of having a pure breeding green seeded offsprings (2 marks) What is the probability of having a yellow-seeded plant in F2 generation, when a true breeder from F1 is crossed with a non-true breeding yellow seeded plant? (2 marks)
Answers
Answer:
Explanation:
To solve this problem, let's represent the heterozygous yellow-seeded plant as "Yy" and the homozygous yellow-seeded plant as "YY."
i. When crossing a heterozygous yellow-seeded plant (Yy) with a homozygous yellow-seeded plant (YY), we can set up a Punnett square to determine the possible offspring genotypes:
Y Y
y Yy Yy
y YY YY
ii. The genotypic ratio is 2:2 or 1:1 for the possible offspring genotypes: Yy and YY.
The phenotypic ratio is also 2:2 or 1:1 for the possible offspring phenotypes: yellow-seeded (YY and Yy).
Question 2:
To determine the probability of specific outcomes, we need additional information about the parental genotypes and their inheritance patterns. Please provide the genotypes of the true breeder from F1 and the non-true breeding yellow-seeded plant for a more accurate calculation.
What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
Answers
Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.
The chromosome is composed of two sister-chromatids.
During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.
The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

Which organ system is responsible for transporting nutrients, gases, and hormones through the body?
Which organ system helps waste gases such as carbon dioxide leave the body?
Which organ system includes the brain?
The kidneys and the urethra are part of which body system?
Answers
1. In the organ system, The circulatory system is responsible for providing gases, nutrients, and hormones around the body.
2. The organ system that helps waste gases such as carbon dioxide leave the body is the respiratory system.
3. The organ system that includes the brain is the nervous system.
4. The kidneys and the urethra are part of the urinary system.
1.The circulatory system is the organ system in charge of delivering nutrients, gases, and hormones throughout the body. It consists of the heart, blood vessels, and blood, which work together to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps oxygenated blood to the tissues, delivering nutrients and oxygen, while the blood vessels act as a network of highways to distribute these substances to cells and organs.
2. The respiratory system is the organ system that assists waste gases such as carbon dioxide in leaving the body. The lungs, airways, and respiratory muscle are all part of it. During respiration, oxygen is taken in and carbon dioxide is removed from the body. The lungs exchange gases by inhaling oxygen-rich air and exhaling carbon dioxide.
3. The nervous system is the organ system that contains the brain, as well as the spinal cord and nerves. The brain is the body's command and control Centre, coordinating and regulating many physical activities and processes.
4. The kidneys and the urethra are part of the urinary system. The urinary system is responsible for filtering waste products, excess water, and toxins from the blood, producing urine, and eliminating it from the body. The kidneys filter the blood, removing waste and excess substances, while the urethra is the tube that carries urine from the bladder to the outside of the body during urination.
These organ systems work together to maintain homeostasis and ensure the proper functioning of the human body.

Answers
Answer:
1. The gluteus maximus is the biggest muscle in the human body. More commonly known as the glutes, this muscle is located behind your hips and is responsible for things like keeping your body upright and helping you walk up stairs. Basically, your glutes are responsible for most all movement of the lower body.
2. The largest muscle in your upper body, the lattismus dorsi (more commonly known as the lats) is a broad muscle located across the lower part of the back
3. Your quadriceps are another large muscle group located on the front of your thighs. They're responsible for helping extend your knees and bend your hips, and made up of four different muscle heads: The rectus femoris, vastus lateralis, vastus intermedius and vastus medialis. Your quads are key for general everyday movement, like walking, running, squatting, cycling and keeping balance. This means that a muscle strain —which commonly occurs when you overstretch or pull your quad — could leave you out of commission for a while.

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
an increase in food availability
an increase in pollution
a decrease in tuna fishing
a decrease in tuna predators
Answers
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
Other options, such as an increase in food availability, a decrease in tuna fishing or a decrease in tuna predators, are environmental factors that contribute to increased genetic variability.The environmental factor that leads to a decrease in genetic variation in a population of tuna is :
B) An increase in pollution
The link between genetic variation and environmental pollution, the latter being a factor that adversely affects the variation of a particular population. The concept of environmental stress not only means low reproductive rates, but is also a factor that impedes genetic exchange with other populations and reduces the genetic diversity of the population. For this reasons, increased contamination means a decrease in the genetic diversity of the tuna population.Thus, the correct answer is B.
