Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.
1) carbon dioxide
2) hydrogen
3) oxygen
Answer:
How does cellular respiration work in animals?
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Three samples of cells from three different patients were unlabelled. One sample was from an 85-year-old man, one was from a 5-year-old boy, and one was from a person with skin cancer. How could you determine to which patient they belonged?
The 85 year old man will have shorter telomeres.
The 5 year old will have long telomeres.
The person with skin cancer will have an abnormal karyotype and abnormal nucleus shape and size during interphase.
Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.
Answer:
The correct answer would be - low flower density and low deep flower proportion
Explanation:
To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.
To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.
Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.
This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.
How do flower visitors diverse the traits?It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.
The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.
In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.
Therefore, the correct answer is low flower density and low deep flower proportion.

to which class of macromelules do anitbodies belong to
Pls answer now I am giving 40 points
Answer
:proteins
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.
Explanation:
Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Answer:
Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses

What are two ways in which cells use the energy temporarily stored in ATP?
Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways
The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.
What is Active transport?
Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.
ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults
Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?
Answer:
This question lacks options, however, it can be answered based on general understanding.
The green plant died because of absence of LIGHT
Explanation:
Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.
Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.

Answer:
Net force
Explanation:
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
