Answer: Serve different function

Explanation:

The different types of the organism on earth serves different functions in the body. This is known as the cell differentiation.

In this way, different functions inside the body is performed by different organs of the body.

The differentiation of cell means that different cells of the body performs different functions of the body.

The liver cells in the liver is equipped for the digestion of fat in the body. The skin is equipped to protect the body from external pathogens et cetera.

Answer:

2. serve a different function

Explanation:

Communities in a primary succession include

-barren rock

-bacteria and fungi

-mosses and lichen

Further Explanation:

Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:

• colonizing species exploiting uninhabited areas (Primary succession)
• becoming a habitable and increasingly complex community
• there is increased diversity of organisms (Secondary)

The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.

However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

Answer:

Hormones that stimulate endocrine glands to release other hormones are thyroid stimulating hormones (TSH).

Explanation:

• TSH regulates thyroid gland to produce its hormones like thyroxin and triiodothyronine.

• This stimulating hormone is responsible for the thyroid gland to help in balancing the metabolism in the body.

• If your body is secreting less thyroxin then TSH sends signal to thyroid gland to balance the level of thyroxin on the body.

• So, thyroid stimulating hormone is for the checking of level of hormones in the body to bring it in balance.

A. An actual patient is observed in a clinical trial. Clinical trials are research studies that involve human participants.

What is the aim of a clinical trial ?

The aim of a clinical trial is to evaluate the safety and efficacy of a medical intervention, such as a drug, device, or vaccine. Patients who participate in clinical trials are closely monitored to assess the effects of the intervention on their health. The results of clinical trials can inform medical practice and help to improve patient outcomes.

Option B, "A dangerous situation," is not relevant to a clinical trial, which is conducted in a controlled and ethical manner to ensure the safety and well-being of participants.

Option C, "A microscopic virus," may be studied in a laboratory, but it is not directly observed in a clinical trial. However, the effects of a drug or vaccine on a virus may be observed in a clinical trial involving human participants.

Option D, "A busy hospital," is also not relevant to a clinical trial, which is usually conducted in a specialized research facility or hospital with dedicated staff and resources.

Explanation:

Answer:

By action potential nerve contract the muscle

Explanation:

The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.

Answer:

Explanation: do you have a picture, for your question?

Answer

Frequency of stimulus can change the force of muscle twitch.

Explanation

Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.

Force of muscle twitch varies according to the total number of motor units as well as the net amount of contractional force and pull required.

Explanation:

The contraction in the muscle that takes place due to the single action potential travelling down the motor neuron of a muscle fiber which leads to a muscle twitch. A motor neuron (alpha) innervates and branches into the muscle fibers (skeletal) and together forms a motor unit.

Depending upon the size of this motor unit, the force of muscle contractions vary. In areas which undergo fine coordinated movements like eye muscle contraction, finger contraction, etc which encompasses smaller motor units, the force of contraction is lower. In areas like the legs and back, where the motor units are more, the force of contraction is higher.

The force and the tension pull experienced and exerted by the muscle vary depending upon the movement required. The muscle twitches are classified according to the force of contraction – fast (high force-short duration), slow (low force long duration) and intermediate twitch (fast and slow).

Water and energy are the raw materials for bread making

Explanation

Gluten is formed from water and water also gives consistency to dough. Roughly 40% of dough is water. It also provides medium to dissolve sugar and enzymes in dough making for bread. It does gelatinisation of starch that helps in easy digestion of bread. Energy and heat are used to distribute water through the bread.

Answer:

Nitrogen Fixation refers to the process of conversion of atmospheric nitrogen gas to usable form by living organisms.

Explanation:

NH3, i.e. fixed form of Nitrogen is an important component of DNA and proteins which is needed by living organisms.

The biological conversion of Nitrogen happens by conversion of Nitrogen in the atmosphere, i.e. N2 is converted to ammonia, NH3. This is performed by "Nitrogen-fixing bacteria". They play a major part in the "nitrogen cycle" by converting "atmospheric nitrogen" into 'fixed' nitrogen which can actually be used by living organisms, be it plants, humans or animals.

Answer:

Nitrogen fixation refers to the conversion of atmospheric nitrogen gas (N2) into a form usable by plants and other organisms.

Answer:

pyruvate

Explanation:

Pyruvate, the product of glycolysis, is converted to acetyl-CoA, the starting material for the citric acid cycle, by the pyruvate dehydrogenase complex. Acetyl-CoA donates its acetyl group to the four-carbon compound oxaloacetate to form the six-carbon citrate.

Answer:

Pyruvate is the first intermediate compound in the Krebs cycle.

Explanation:

• Pyruvate is the product formed from the glycolysis. In the Krebs cycle the compound pyruvate is converted into acetyl CoA.

• This is carried out into three steps. The 'Krebs cycle' is also called as the 'citric acid cycle' due to this reason.

• Multiple molecules of this pyruvic acid are used in yielding the high energy for the process. These chemical reactions are carried out by all anaerobic organisms.

A mutation can produces a deleterious effect due to the production of abnormal proteins during protein synthesis.

What is a mutation?

A mutation is an abnormal change that occurs in the sequence of nucleotides in a DNA molecule.

Types of mutation include:

• substitution
• deletion
• insertion

Mutations may have either no effect, a positive effect or a deleterious effect on the organism.

A mutation that produces a deleterious effect is due to the production of abnormal gene products such as proteins.

Answer:

B)This mutation is a deletion mutation resulting in a frameshift. This would result in a different reading of the codons following the mutation, causing a different translation from the original strand. The protein being created could be abnormally short, abnormally long, and will most likely not be functional.

Explanation:

It is mutualism because the bacteria receives carbon from the pea plant, while the plant uses the ammonia to make amino acids. So, the correct option is D.

What is Mutualism?

Mutualism is defined as an ecological interaction between two or more species where each species has a net benefit which is a common type of ecological interaction.

Rhizobia are bacteria that live on the roots of some plants, including legumes such as the pea plant, that convert an element in the environment into ammonia, which is an example of mutualism because the bacteria obtain carbon from the pea plant, while the plant uses ammonia.

One more example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra.

Therefore, the correct option is D.
