Answer:

A. He has a large buildup of lactate in his muscles.

Explanation:

Ideally, our body cells, via the process of aerobic cellular respiration, need oxygen to break down glucose. However, during rigorous activities or exercises, oxygen can become unavailable for use. In this case, the body cells switch to use another way of cellular respiration, which is FERMENTATION.

This fermentation causes a build up of lactic acid/lactate (its byproduct) in the cells of the muscles being used, which physically causes a burning and aching sensation just as the case of this hiker. The climbing of the steep path is causing causing the fast usage of oxygen in his cells.

Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A
Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.


Hope t help!

write down at least twenty things that animals contribute to your life and the lives of those around you. Once you have the list
trasher [3.6K]

Answer:

Trust me i feel u  and understand so heres my answer so that u can feel at ease

Explanation:

Food- Most Ag animals, (Such as farm animals) Are mainly a source of food. This role is vital to my life and everyone else because Food is one of the major things we need for life. This item is produced through farming and Manufacturing. The main contributors to this would be Cows, Sheep, Pigs and Chicken.

Clothing- Some animals fur or Wool can be used as a type of base material for clothing. This Role is vital to my life and everyone else because Clothing is one of the major things we need for life. This item is produced through Shearing, Hunting and/or Manufacturing. The main contributors would be Sheep, but sometimes game animals (such as bears or deer) are used too

Milk- Cows and Some goats Makes milk. This is an important role because Milk is used in a variety of foods such as Cakes, Cereal, Oatmeal, etc. The main contributor would be Cows, however some times Goats milk can be used as well. Milk is mainly processed through pasteurization

Pets- Some animals (cats, dogs, birds, etc.) Can be used as Pets. This role is important because Pets are Stress relievers and can help mentally with what could go on around the world. Most pets are breed through selective breeding. The main contributors are Cats, Dogs and Fish.

Butter- Animal fat can be used to make butter. This is a important role because butter is also used in a variety of foods, such as cakes, Meats, etc. Animal fat left over from butchering animals can be process into butter. Most ag animals that are used for meat, (cows pigs) are used. A second way to make butter would be to use goats milk.

The picture shows the dihybrid cross of 2 guinea pigs.
Pepsi [2]

Corrected Question:

The picture shows the dihybrid cross of 2 guinea pigs.

1. What is the genotype of the parents?

2. What is the phenotype of the parents?

3. What is the genotype of their baby guinea pig (in the empty box)?

a. BbRr - black rough fur

b. Bbrr - black smooth fur

c. bbRr- white rough fur

d. bbrr - white smooth fur

Answer:

Genotype of parents is BbRr as seen in the cross.

Phenotype of the parents is black rough furred.

The genotype of the baby in the empty box is bbRR.

Option D

<h3><u>Explanation:</u></h3>

This representation of the genetic crossing is called as Punnet square, after the name of the scientist who discovered this process to denote the probability of finding the required genotype in a statistical way.

Here both the parents are heterozygous black and rough furred, with the genotype of BbRr.

So the gametes from the parents are = BR, Br, bR, and br from both the parents which are represented in the Punnet square.

Thus we can get 16 types of genetic combinations among the offsprings.
