The cell structure is formed according to their function.

Explanation:

Form and function are related to each other in human cells because the cells structure is formed according to its function. epithelial tissue are the group of cells that act as coverings of the body and controlling the movement of materials across their surface whereas muscle tissues are group of cells that are responsible for the movement of the body. Both tissues has different structure which allows it to perform different function.

Explain how a chemical reaction occurs using the following terms
Reactant
Product
Activation energy
Bond
Endothermic
Exothermic
Rate

Answers

For a chemical reaction to occur, activation energy is required. Using the activation energy, reactants form products by breaking bonds which require energy. This type of reaction is an endothermic reaction. When products are formed, bonds are formed back by releasing energy. This type of reaction is an exothermic reaction. When activation energy is used for a reaction, a catalyst is not required. Adding a catalyst to the reaction causes the rate of reaction to increase.

A chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires a minimum amount of energy.

A reactant is a starting substance in a chemical reaction, whereas products are formed at the end of the reaction.

The rate of reaction is the velocity of the chemical reaction.

Activation energy refers to the minimum amount of energy required to activate reactants and thus start a chemical reaction.

The chemical reactions store/release energy by destroying/building chemical bonds between atoms/molecules.

Exothermic reactions release energy when the bonds are formed; whereas endothermic reactions consume energy.

In conclusion, a chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires energy. These reactions can be exothermic processes or endothermic processes.

Which of the following functions at the same organizational level as the kidney in the human
excretory system?

Answers

Answer:

Its the Urinary bladder

Explanation:

A. skeleton

B. epithelial tissue

C. urinary bladder

D. a squamous cell

The correct answer as to which functions at the same organizational level as the kidney in the human excretory system would be the urinary bladder. The correct option would, thus, be C.

There are 4 progressive levels of organization as far as life is concerned. These are:

celltissuesorganssystems

The cell is the basic unit, tissues are made of 2 or more cells, organs are made from multiple tissues, while systems are formed from numerous organs.

The kidney is at the organ level and so is the urinary bladder. Skeleton is a system made from different organs, epithelia tissues are tissues, while squamous cells exist at the cellular level.

B. bacteria

C. protista

D. archaea​

Answers

D - Archaea

All organisms are unicellular & they live in extreme environments, like heat and salt.

The kingdom that contains single-celled organisms that live in extreme environments is archaea. The correct option is D.

What are single-celled organisms?

A single cell makes up a unicellular creature, also referred to as a single-celled organism, as opposed to a multicellular organism, which is made up of numerous cells. Similar to Eukarya, Archaea have RNA polymerases that are more complicated than those of bacteria.

Archaea do not have peptidoglycan in their cell walls, in contrast to bacteria. The membrane lipid bonding of archaea differs from that of bacteria and eukarya.

According to the research, increase in substrate and temperature are factors that limit enzyme activity.

What are enzymes?

It is a protein that catalyzes the biochemical reactions of metabolism and acts on molecules known as substrates.

The way that the enzyme has to carry out its catalytic activity will be in the first place to bind with the substrate, this is limited by different factors such as the concentration of the substrate and the temperature.

Adult stem cells are referred to as Choose... , because they can differentiate usually only into the cells of the tissues where they are found, whereas embryonic stem cells are Choose... because they can develop into any of the body’s cell types, although they cannot form the tissues surrounding the embryo.

Answers

Answer:

The correct answer is -

1. totipotent

2 multipotent

3. pluripotent

Explanation:

The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.

Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph

Answers

Answer: definitely C will help you

Explanation:

Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

What is the main reason of emission of carbon?

According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.

According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.

This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.

These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
