Pepper is an elite competitive cyclist who wanted to gain a physiological advantage over his competitors. He decided to have his own blood drawn and stored so that it could be infused into him prior to competition. What is the theory behind this practice? How effective is this procedure?
Answer:
Blood doping
Explanation:
This is called blood doping and many athletes have used it (its cheating btw). They'll go to a place with high elevation and train and then take their blood. After they go back to a lower elevation they inject that blood back in and it allows them to be able to perform better. So in this case, the cyclist would be able to perform better over her competitors (more energy/able to exert more energy for longer period of time, etc.)

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
how is the pseudo-ruminant digestive system different than human digestive system?
Answer Ruminants differ from non-ruminants (called monogastrics) because they have a four-chambered stomach. The four compartments are called the rumen, the reticulum, the omasum, and the abomasum. The rumen and the reticulum are connected and work in concert and are therefore sometimes called the “reticulorumen”.:The digestive enzymes of these animals cannot break down cellulose, but microorganisms present in the digestive system can. Since the digestive system must be able to handle large amounts of roughage and break down the cellulose, pseudo-ruminants have a three-chamber stomach. hope this helps have a nice night ❤️❤️❤️
Explanation:
Explanation:
ruminant animals have 4 intestine
What food item will provide 1 mole of sodium in the least mass? What is that mass?
Answer:
Can of soup.
Explanation:
Can of soup will provide 1 mole of sodium in the least mass because the concentration of sodium in can of soup is higher than other food items. The can of soup has 300 mg of sodium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 190 mg, 150 mg, 80 mg, and 180 mg of sodium respectively which is lower than can of soup so we can say that less amount of soup provides more sodium.
A bird fluffs its feathers to trap body heat to keep warm during winter months. This is an example of
A bird fluffs its feathers to trap body heat to keep warm during the winter months. This is an example of homeostasis. By trapping the heat, the bird maintains its body temperature.
What is homeostasis?Homeostasis is a condition in which the organism tries to maintain balance between the inside and outside environments. Different animals live in different geographical regions of the earth.
So, they have different adaptations to the environment. The animals that live in an extreme hot climate have different adaptations, such as modifications in the urinary system to release less water, water-preserving organs, etc. They have a large surface area, so heat can be released well.
Animals or birds who live in a cold area show different adaptations, such as more hair on their bodies and more fat, so that they can prevent heat loss and keep their bodies warm in order to maintain normal cellular activities. By doing so, the bird attempts to maintain its normal body temperature.
Hence, the bird is doing so in order to maintain the body's homeostasis.

Which of the following is the best example of natural selection?
(1) A cheetah living in a zoo lives 10 years longer than average.
(2) The shell of a crab becomes harder over time as a result of being hunted by a predator.
(3) A person's muscles become firmer from riding a bike for exercise.
(4) A population of a rabbit's decreases in number as some move to another area.
Answer:
A cheetah living in a zoo lives 10 years longer than average.
Explanation:
because Cheetahs living in captivity generally live a great deal longer than those in the wild, the life span of wild cheetahs is about 8 to 10 years, as opposed to 12 to 17 years for those in captivity according to the National Zoological Park, a sure fire sign of a healthy life.
The best example of natural selection is that the shell of a crab becomes harder over time as a result of being hunted by a predator, which is mentioned in Option 2, as the other options are not absolutely correct for it.
What is natural selection?Natural selection is the process where certain traits that are advantageous to an organism's survival and reproduction become more common in a population over time. In option (2), the harder shell of a crab is an adaptation that helps the crab avoid being preyed upon by its predator. As a result, the crabs with harder shells are more likely to survive and reproduce, passing on their advantageous trait to their offspring. Over time, the population of crabs will have a higher proportion of individuals with harder shells, leading to the evolution of this trait in the population.
Hence, the best example of natural selection is that the shell of a crab becomes harder over time as a result of being hunted by a predator, as mentioned in Option 2.

Peppered moths in the early 1800's were mostly white-winged insects. During the Industrial Revolution, these moths had a hard time staying camouflaged against the ash-covered environment near factories. As a result, the moths started producing more offspring that had gray wings. This gradual change in the genetics of the moth is called an?
Answer:
Evolution.
Explanation:
Evolution is the gradual change that occurs in the genetics of an organism. Change in environment of an organisms play an important role in evolution. Evolution leads to the change in the physical structure of an organisms that is compatible to that environment so gradual change occurs in the genetics of the moth having gray wings which helps the moth to hide in the ash.

The greater an object's ____ the stronger the gravitational force on it.
A. mass
B. distance
C. weight
Answer:
The greater an object's mass the stronger the gravitational force on it.
The greater an object's mass, the stronger the gravitational force on it.
What is the force of gravity?The force of gravity depends directly on the mass of the objects and inversely on the distance between them. Therefore, an object with a greater mass will have a stronger gravitational pull on other objects, regardless of their distance apart.
The weight of an object is a measure of the force of gravity on it and is equal to the object's mass multiplied by the acceleration due to gravity. So, while mass and weight are related, they are not the same thing. Mass is a measure of an object's amount of matter, while weight is a measure of the force of gravity acting on an object.

A plant cell has a plant wall so a and b can be disregarded. Mitosis ends with a cleavage factor dividing the cell in two so d represents the last stage.
What is Mitosis?
A single cell divides into two identical daughter cells during the process of mitosis (cell division).
A cell divides into two genetically identical daughter cells during the process of mitosis, which is also known as cell duplication or reproduction. When used strictly, the term "mitosis" refers to the duplication and distribution of chromosomes, the biological units that house genetic material.
The thickening and coiling of the chromosomes signal the start of mitosis during prophase. A spherical structure known as the nucleolus contracts and vanishes.
Therefore, A plant cell has a plant wall so a and b can be disregarded. Mitosis ends with a cleavage factor dividing the cell in two so d represents the last stage.

The tropical rainforest is the most coplex and species rich biome in the world but it is soils are nutrient poor . What is the reason for this
Answer:
because nutrients cannot be stored in the soil for a long time
Explanation:
In rainforests, high temperatures and humid conditions lead to the rapid decomposition of the organic matter in the soils, which releases nutrients rapidly. However, rainforest soils are poor in nutrients due to rains that wash dead organic material from them. Moreover, rainwater is filtered naturally into the ground, thereby extracting (leaching) nutrients off the surface.
