Answer:
its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored
It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.
What is the number of chromosomes in humans ?It is having 23 pairs of chromosomes that is having total of 46 chromosomes.
Because meiosis just creates cells which are destined to be the gametes and in this reduction in the chromosome number is just critical that is without the process, the union of the two gametes that are during the fertilization that will result in the offspring with just twice of normal number of the chromosomes.
Haploid cells in the humans are just produced out by meiosis. This is type of the cell division in which the single diploid parent cell just divides to just produce four with the non-identical type of the haploid daughter cells. In meiosis is just used to get the type of the produced type of gametes and is are a necessary kind of precursor to the sexual reproduction.

Match each part of the kidney with the correct label.
Kidneys are externally surrounded by a three-layer capsule, and internally composed of the cortex, medulla, and pelvis. In the image, 1) Cortex, 2) Medulla, 3) Sinuses , 4) Capsule.
What are the kidneys?
The kidneys are bean-shaped, bilateral urinary organs located at each side of the vertebral column, under the ribs, and behind the abdomen (superior right and left abdominal quadrants).
Their main function is to filtrate blood, eliminate wastes and water excess through urine, and keep internal homeostasis.
When blood enters the kidneys, water, salts, and other waste substances are eliminated as urine, and the filtrated blood returns to the organism.
Kidneys are composed of different parts.
Externally,
Renal fascia ⇒ External layerRenal fatty capsule ⇒ Media layerRenal fibrous capsule ⇒ Internal layer
Internally,
the renal cortex ⇒ produces erythropoietinrenal medulla ⇒ contains nephrons, which filtrate blood and produce urine.renal pelvis ⇒ ilion
The medulla is arranged as pyramidal masses composed of tubular structures. In between the pyramids, there are renal papilla and calyces.

Which term refers to the microscopic physical gap between the presynaptic and postsynaptic neurons at a chemical synapse
The gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.
The neurons are the smallest units of the nervous system. They are equally referred to as the nerve cells.
The presynaptic neurons that receives the fired action potential through its axon terminals.
This leads to release of neurotransmitters found in the synaptic vesicles of the presynaptic neurons.
These neurotransmitter are released into the physical gap between the presynaptic and postsynaptic neurons called the Synaptic cleft.
The neurotransmitters are then received by the postsynaptic neurons.
Therefore, the gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.

Which of the following types of agriculture is most likely to use economies of scale?
Biodynamic
Conservation
Industrial
Slash-and-burn
Among the options listed, the most likely to use economies of scale (given our understanding of this concept) is Industrial Agriculture.
The concept of economies of scale is the idea that a business entity uses mass production of a product in order to be able to reduce the cost of every individual unit. This is a very common practice in industrial work environments.
Like most industrial work systems, Industrial Agriculture is focused on efficiency. The companies in question often use mass production as a method of reducing costs, given that by completing the process on a bigger scale, they can create more units of a product while sharing the same cost.
This system is the exact definition of the use of an economy of scale, therefore we can confirm that the Industrial Agriculture option is correct for the question at hand.

Dna is synthesized through a process known as DNA Replication.
DNA is synthesized through a process known as - DNA replication or semiconservative replication.
DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA
Step 2since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.
Step 3
the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one
Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.
