A premise that could be used to back up the conclusion that urchins are undergoing natural selection would be that urchins with short spines are extremely vulnerable to predators. Option C.

Urchins with short spines are extremely vulnerable to predators.

This is because natural selection is a process in which organisms with certain traits are better able to survive and reproduce than those without those traits, and those traits are then passed on to future generations.

In this case, the vulnerability of urchins with short spines to predators means that they are less likely to survive and reproduce, while those with longer spines are more likely to do so.

Therefore, the trait of long spines is being naturally selected for in the urchin population. The other options do not provide evidence for natural selection.

Homeostasis can also occur at pH and nutrition levels, for instance. Particles travel through a process called diffusion from a region where they are more concentrated to one where they are less concentrated. Diffusion is employed to maintain a cell's equilibrium concentration when homeostasis is under danger.

Diffusion is the overall net movement of anything from a higher concentration to a lower concentration. A gradient in the Gibbs free energy or chemical potential drives diffusion.

Molecules go through the cell membrane due to diffusion. In order to balance the internal conditions of the cell with the external environment, molecules of a substance migrate over a gradient of concentration.

Thus,  Diffusion is employed to maintain a cell's equilibrium concentration when homeostasis is under danger.

The level of phosphorylated signaling protein is the dependent variable, and the zero time point, at which the hormone is introduced and may take some time to begin acting, serves as a negative control for the effects of hormone addition.

A necessary hormone is an insulin. Blood sugar levels are regulated, and it aids in the conversion of food into energy. Your body can't produce enough insulin or can't use it correctly if you have diabetes. For injection (shot), injectable pen, or pump administration, your doctor may prescribe human-made insulin. Insulin powder can also be inhaled.

Your pancreas secretes insulin, a hormone that naturally occurs and aids in the body's usage of sugar as fuel. The inability of your pancreas to produce or release the insulin required to regulate your blood sugar levels may lead to diabetes if it doesn't function as it should.

Answer:

Correct Answer is B - Survival of all species of organisms depends greatly on abiotic factors.

Explanation:

The correct answer is ATP releases energy as a phosphate bond is broken.

ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) when a phosphate group is removed from ATP, resulting in the release of energy. This process is known as hydrolysis, where water molecules are used to break the bond between the terminal phosphate group and the rest of the molecule.

During cellular metabolism, ATP serves as the primary energy currency of the cell. When energy is required for various cellular processes, the phosphate bond in ATP is broken by an enzyme called ATPase. This enzymatic hydrolysis reaction cleaves off one of the phosphate groups, resulting in the formation of ADP and an inorganic phosphate molecule (Pi). The released phosphate group is then available to be used in other cellular reactions.

The conversion of ATP to ADP is an essential part of energy metabolism in cells. The energy released during this process is utilized to drive various cellular activities, such as muscle contraction, active transport of molecules across cell membranes, and synthesis of macromolecules. Once ATP is converted to ADP, it can be further hydrolyzed to AMP (adenosine monophosphate) if more energy is needed. Ultimately, the energy stored in ATP is released when the phosphate bond is broken, allowing cells to perform their vital functions.

heterotrophs animals.

The characteristic that defines animals but not plants is that animals, but not plants, are heterotrophs.

Heterotrophs are living organisms that are incapable of synthesizing their own food, like autotrophs.

Plants are autotrophic in nature meaning that they can produce their own food using sunlight energy.

All animals are heterotrophic in nature i.e. do not exhibit any form of autotrophism.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

The correct answers are: C. energy, D. water, and F. carbon dioxide.

Organisms use oxygen in a process called cellular respiration to break down sugar, which is a source of energy, into other products. During cellular respiration, sugar is broken down into water and carbon dioxide, and energy is produced in the form of ATP (adenosine triphosphate). Oxygen is consumed in this process, and carbon is a byproduct. Nitrogen is not involved in the breakdown of sugar.

In summary, the products of the breakdown of sugar using oxygen are energy, water, and carbon dioxide.

There is no cartilage but there is epithelium

Explanation:

The pharynx of the human respiratory system does not contain cartilage.

The pharynx,  part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for  air and food. The gorge is made up of several regions, each with its own distinctive features.

The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated  epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.

These regions also lack cartilage but  are lined with  stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.
