5. Assume that blood type is inherited as A and B dominant over O, but A and B are codominant
over each other. Genotypes (la la) and (lai) are then phenotypically type A, genotypes (le le) and
(lei) are type B, genotype (la ls) is type AB, and genotype (ii) is type O blood. A man with blood
type la la marries a woman with type AB blood. What are the genotypic and phenotypic ratios of
the children?
Answers
Answer:
Genotypic ratio = 1 (IaIa) : 1 (IaIe)
Phenotypic ratio = 1 (Type A) : 1 (Type AB)
Explanation:
This question involves a single gene coding for the inheritance of blood type in humans. However, three alleles (multiple alleles) are responsible for this inheritance. Alleles ia and ie, according to the question, are dominant over alleles i.
According to this question, a man with blood type "laIa" (blood type A) marries a woman with type AB blood (IaIe). The following gametes will be produced by each parent:
IaIa - Ia and Ia
IaIe - Ia and Ie
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
2 IaIa, and 2 IaIe offsprings
Therefore,
Genotypic ratio = 1 (IaIa) : 1 (IaIe)
Phenotypic ratio = 1 (Type A) : 1 (Type AB)

a. What type of organism is the grass?
Answers
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
The grass is the producer of the food chain. Producers are the organisms in the food chain which produce food in a food chain.
What are the producers in a food chain?Producers are the organisms which make their own food in a food chain through photosynthesis. Producers are also known as autotrophs. They get energy to work from the chemicals or the sunlight, and with the help of water, these organisms convert the light energy into useable energy that is the chemical energy in the form of sugar or food particles. The most common example of a producer are the green plants.
Producers are any kind of green plants. Green plants make their food by taking sunlight and using this energy to make glucose (carbohydrate). The plant uses this carbohydrate, also called glucose to synthesize many products, such as wood, leaves, roots, and bark. Grasses are also an example of producers in a food chain as they produce glucose.

Which of the following stages of cellular respiration involve cytochromes?
I. glycolysis
II. Krebs cycle
III. electron transport chain
A. III only
B. II and III only
C. I only
D. I, II, and III
E. II only
Answers
Answer:
A. III only
Explanation:
Cytochromes are found only in the mitochondrial membrane as part of the electron transport chain. They are vital to the downward cascade of energy as electrons are passed from the NAD+ and FAD produced during glycolysis and the Krebs cycle into the electron transport chain to eventually produce ATP.

What are the two types and functions of vascular tissue?
Answers
Answer:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle

The family is causing less trees to be cut down.
Answers
Answer:
The answer is B!
Explanation:
I know this because if the family was using less renwwable resourses it wouldn't be a problem. And if the family was causing less fertlizer to enter the water, that would be helping. So would causing fewer trees to be cut down. So it is all about the process of elimination! Hope I could help
A family decides to use their bicycles to get to the mall on weekends instead of driving a car, and the family is helping the environment by using fewer non-renewable resources, which is in option B.
What are non-renewable resources?Using bicycles instead of driving cars is an environmentally friendly choice because it helps reduce the consumption of non-renewable resources, such as fossil fuels, as fossil fuels are a limited resource that takes millions of years to form and their use contributes to air pollution and greenhouse gas emissions, which are major contributors to climate change. In addition to the environmental benefits, cycling can also have positive health impacts. Regular cycling can help improve cardiovascular health and reduce the risk of chronic diseases such as obesity and diabetes.
Hence, the family is helping the environment by using fewer non-renewable resources, which is in Option B.
