The apparatus shown below measures the oxygen consumed by a small animal. As oxygen is consumed, the water droplet moves closer to the flask. Because carbon dioxide is absorbed by the potassium hydroxide solution on the filter paper, it does not affect the results.

You are performing a lab in biology class to determine, quantitatively, if temperature affects the rate of oxygen consumption by a small animal. You will be testing the oxygen consumption of the animal at 0ºC, 15ºC, and 30ºC.

1) Write a prediction about the relationship between oxygen consumption and temperature. (1 point)

2) Using this apparatus, or a similar one, write a procedure to test your prediction. Procedures should be detailed, specific, and written in numbered point form. (2 points)

The control group in an experiment to show that the hormone estrogen increases the milk yield of dairy cows is the presence of cows that have not been administered with the addition of this hormone or inhibited in the production of estrogen.

The control group in an experiment is a given group of the sample which is not under treatment, which allows us to make comparisons with the target group.

Therefore, with this data, we can see that the control group does not receive the experimental treatment.

The rate of change per year of grizzly bears in this time period is B. -1.2 grizzly bears/year.

Rate of change (ROC) refers to how fast something changes over time. Thus, it is the acceleration or deceleration of changes (i.e., the rate) rather than the magnitude of individual changes. Rate of change is used in finance to understand price returns and identify momentum in trends.

It is frequently used when discussing momentum, and it can be expressed as a ratio of a change in one variable to a corresponding change in another. The slope, rise over run, or change in over change in is the rate of change for a line.

In this situation, tjere were 42 grizzly bears in a provincial park in 1980. There were 30 grizzly bears in the same provincial park in 1990.

The rate will be:

= (30 - 42) / 10

= -12 / 10

= -1.2

Cell differentiation is an essential process for the overall development, growth, reproduction and longevity of the complex multicellular organisms.

Cell differentiation is the process in which the stem cells become more specialized into different cells. Cell differentiation is an essential process because it creates diversity in life on the planet Earth. It creates diversity within the cells of the body of an organism and allows the cells to create unique structures which fit their individualized functions in that organism.

Cell differentiation is an essential process for the development, growth, reproduction, and longevity of all the complex multicellular organism as it is responsible for the formation and maintenance of different organ systems in an organism.

The biotic potential can go above the graph, but only for a limited period of time.

What is the biotic potential?

Biotic potential is the maximum reproductive rate of a population when there are no limiting factors such as resources, space, or competition. This rate is determined by the species' fertility, survival rates, and longevity. It is an important concept for population ecology because it can provide a measure of how quickly a population could theoretically grow, given ideal conditions.However, if the environment changes or the resources become scarce, the population size will decrease. Therefore, if the biotic potential goes above the graph, it is likely to be a temporary increase that will not be sustained in the long run.

What do you mean by Population?
Population is a term used to refer to the total number of people, animals, or other living organisms in a given area. It can be used to describe the size of a city, country, continent, or the world. Population can also refer to the total number of individuals in a specific group, such as a species or ethnic group.

hope it helps. Please mark brainliest

Answer:

N2

Explanation:

Nitrogen is an element, not a compound. It is found in nature as nitrogen gas, also called dinitrogen, with the chemical formula N2, and makes up 78% of the atmosphere. It is a diatomic element because it is composed of two nitrogen atoms chemically bonded.

Direct harvesting can be stopped by making stringent laws and follow them, by maintaining the biosphere reserves and also harvest species in a limited number in an environment.

Direct harvesting can be referred to take a species out of it's natural environment. We need to directly harvest various organisms for resources that support our population growth and maintenance. However, direct harvesting such as overfishing and the use of drift nets has threatened the aquatic biodiversity on a large scale. Likewise, we have also hunted and poached endangered animals to the point of near extinction.

Direct harvesting can be stopped by controlling fishing by making strict laws and apply them. We can also restrict the entry of people in the areas where large population of animals are present as reserve areas.

Proteins are composed of a sequence of amino acids linearly arranged. To accomplish their functions thet must adopt different structures. Primary structure: Amino acid sequence. Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide. Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide. Quaternary structure: The aggregation of multiple polypeptide subunits.

Proteins are molecules composed of several amino acids.

Amino acids are monomers composed of

The R group is what differentiates one amino acid from another one.

Several amino acids linearly arranged and connected by peptidic bonds compose the polypeptide.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid stabilizes the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the amino acid sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

The hydrophilic R-groups stay permanently in the molecule interior, avoiding interaction with water.

Cell function is often compared to the operation of a factory or city as Nucleus. It should be compared to a neighborhood. Thus, option C is correct.

Centrioles are small, cylindrical cell organelles, present near the nuclei of animal cells. They are involved in formation of spindle fibers at the time of cell division that help in proper separation of chromosomes during cell division. Plant cells do not have centrioles.

Nucleus and ribosomes are present in both animal and plant cells, while cell wall is found only in plant cell. Thus, the organelle in diagram that should be listed under 'animal only' will be 'centriole.'
