Answer:

  • <u>Nervous system: </u>

The nervous system is comprised of two main systems, which are the Central nervous system,CNS(Brain and spinal cord) and the peripheral nervous system,(PNS).

  • <u>Basic Unit:</u>

The basic structural and functional unit of the nervous system is the neuron.

Explanation:

  • <u>Frequency of the stimulus and number of receptors in the area:</u>

As the reaction shown by the nervous system towards the change will be all based upon the number of receptors which receives the stimulus and also depends upon the frequency of the change occurred.

  • <u>Cutaneous receptors:</u>

Inside the human body there are number of pain receptors, along with which a limited number of neurons are there to receive the stimulus relating  pressure,cold and warmth. As there are sensory neurons found inside the epidermis layer of the skin which are refereed to as the cutaneous receptors. They receive different stimuli, which are basically the change occurred inside or outside the organisms body.

  • <em>Now, these receptors will detect any change and will direct the muscle spindle fiber either to contract or relax according to the frequency of the stimulus.</em>

Answer:

1.  first part Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins or other molecules, it is called gene expression.  second part Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide by way of special chemical bonds called hydrogen bonds.

2. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

3. Non-coding DNA sequences do not code for amino acids. Most non-coding DNA lies between genes on the chromosome and has no known function. Other non-coding DNA, called introns, is found within genes. Some non-coding DNA plays a role in the regulation of gene expression.

if there were no suppression of dna replication between meiotic divisions but cytokinesis proceeded normally, what is the most l
sergiy2304 [10]
The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces <em>two haploid cells</em>.<span> Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no </span><span>suppression of DNA replication, then meiosis I would produce <em>two diploid cells</em>, and after meiosis II there will be four diploid cells.</span>

The causative agent for malaria is a type of? a. rickettsial agent. b. protozoa. c. bacterium. d. prion. e. virus.
irinina [24]

b. protozoa

One of the four species of protozoan in the genus Plasmodium is responsible for the acute or subacute infectious disease known as malaria.

<h3>A virus or a bacteria causes malaria?</h3>
  • A virus or bacteria cannot cause malaria.
  • Plasmodium, a parasite that often spreads through infected mosquitoes, is what causes malaria.
  • A mosquito consumes Plasmodia that are present in blood when it feeds on an infected human.
<h3>How do protozoa cause malaria?</h3>
  • The female anopheles mosquito bite is the primary method of transmission of malaria, a protozoan infection of the red blood cells.
  • The Plasmodium genus of protozoa is what causes malaria.
  • Four different types of malaria parasites can infect people: Plasmodium malariae, vivax, ovale, and falciparum

After strenuous exercise sore muscles can occur because of?
Anna007 [38]

Answer:

The correct answer is C. A buildup of lactic acid in the tissues.

Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.

Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.

Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.

This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.

In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
