A roan cow is crossed with a red cow. What percent of the offspring will be roan?

Answers

Answer:

Red cows have a dominant red allele and white cows have a dominant white allele. When a red cow mates with a white bull, they can have offspring that have the color that is called Roan which is a red and white spotted appearance. This is an example of co-dominance

Explanation:

CORRECT ME IF I AM WRONG

If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

CO-DOMINANCE:A roan cow phenotype is a product of co-dominance between red (R) and white (W) alleles. This means that a roan cow will have a RW genotype.

If a roan cow is crossed with a red cow i.e. RW × RR, the gametes produced by each cow is as follows:

RW - R and WRR - R and R

Using a punnet square, the following offsprings of cow will be produced: 2RR, and 2RW.

This means that the percentage of roan cows in the offspring will be 50% i.e. ½ × 100 = 50%.

Therefore, If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

The graph shows the growth and reproduction in 4 different cells, A, B, C, and D, over time. Use the graph to answer questions below.

Answers

Answer: A.

Explanation:

Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.

Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.

Endo and exocytosis:
A. Passive transport with the concentration gradient, requiring no energy.

B. Active transport of large molecules with the concentration gradient, thus requiring no energy.

C. Active transport of large molecules in and out of the cell. Requires energy.

Answers

Answer:

C. Active transport of large molecules in and out of the cell. Requires energy.

Explanation:

endo- the formal definition is “endometrial glands and stroma existing outside the endometrial cavity”. Essentially, it is tissue that resembles the endometrium (lining of the uterus), that exists other places. Most often, it is found in the pelvic peritoneum, or the lining of our abdominal cavity.

Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.

Answer:

C. Active transport of large molecules in and out of the cell. Requires energy.

Explanation:

Endocytosis and exocytosis is an active transport of large molecules in and out of the cell, which requires energy.

How does the carbon in grass become part of a lion?

Answers

The carbon ends up in the food the lion eats.
Usually because they are in the same food chain. for example, lions are carnivores (eat other animals). it is likely an animal lions eat are herbivores (eats plants like grass) and therefore, when the lion eats the herbivore, it receives the grass and plants that herbivore ate as well.

Define groundwater and explain how it relates to the terms water table, aquifer, and confined aquifer.​

Answers

Explanation:

Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater. An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. Groundwater separated from atmospheric pressure by relatively impermeable material is termed confined groundwater. When such zones are penetrated by wells, the water rises above the point at which it was first found because a confined aquifer is under pressure exceeding that of atmospheric pressure.
