Answer:
The correct answer would be amino acids.
Translation is the process of formation of polypeptide chain in which nucleotide sequence of DNA is decoded to amino acid sequence via mRNA.
It takes place at ribosomal site in a cell where mRNA is placed between small and large sub-units of the ribosome.
tRNA decodes the mRNA codon sequence with the help of anti-codon site present in it.
Positive interaction between codon and anti-codon site leads to the addition of specific amino acids to the growing polypeptide chain from charged tRNA.
The major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.
Gram-positive bacteria do not contain an outer plasma membrane, whereas Gram-negative bacteria have a lipid-rich outer plasma membrane.
This outer plasma membrane contains lipopolysaccharide (LPS) in addition to phospholipids and proteins.
Moreover, Gram-positive bacteria are also surrounded by thick layers of peptidoglycan.
In conclusion, the major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Answer:
Microbiologists use the gram stain technique to identify the gram-positive and gram-negative bacteria on the basis of the composition of their cell wall.
The major difference between the cell wall of gram-positive bacteria and gram-negative bacteria is that in gram-positive bacteria peptidoglycan is the major component which makes gram-positive cell wall whereas in gram-negative bacteria their cell wall has a thick outer layer of Lippo polysaccharide and a thin inner layer of peptidoglycan.
So in gram stain gram-positive cell wall retains the crystal violet because of the thick peptidoglycan layer and appears violet and gram-negative appears pink as it lacks the outer thick peptidoglycan layer.
B. decreased testosterone secretion
C. excessive beard growth
D. increased spermatogenesis
Answer:
A low secretion of luteinizing hormone(LH) in the normal male adult would cause B. decreased testosterone secretion.
Explanation:
For males the normal range is 1.24 -7.8 IU/L. If LH levels are below the normal range it may indicate a pituitary gland problem. Their pituitary gland may not be making enough LH which may lead to low testosterone.
Hypogonadism is a testicular disorder associated with low testosterone. Low testosterone levels can cause a variety of problems including diminished muscle mass & decreased sex drive as well as decrease in the physical as well as mental energy.
Luteinizing Hormone (LH) in males stimulates the production of testosterone. If LH secretion is low, it would result in decreased secretion of testosterone.
The secretion of Luteinizing Hormone (LH) plays a significant role in the male reproductive system. A low secretion of LH in a normal adult male most likely impacts the production of testosterone because LH stimulates the testes to produce this hormone. Therefore, a decrease in LH secretion would logically lead to a decreased secretion of testosterone (Option B). This decrease in testosterone can further lead to a reduction in sex drive, decreased muscle mass, and other sexual and physical changes.

B. does not use energy
C. uses energy
D. uses energy
When particles move out of a cell through facilitated diffusion, the correct answer B. is the cell does not use energy.
Facilitated diffusion is diffusion mediated via way of means of delivery proteins. The materials flow down the attention gradient from better to decrease attention so it does now no longer require energy.
Facilitated diffusion (additionally referred to as facilitated shipping or passive-mediated shipping) is the system of spontaneous passive absorption (in place of lively shipping) of molecules or ions throughout an organic membrane through precise transmembrane essential proteins. Facilitated diffusion is an instance of passive shipping. Materials pass into or out of cells thru channel proteins. The debris pass from regions of excessive attention to regions of low attention.
Thus it is clear that when particles move out of a cell through facilitated diffusion, the cell does not use energy.

Answer:
Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.
In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.
The biosphere label should be appeared in the system model that contains geological sphere of the earth.
It is the one of the sphere that comprise of the geological sphere of the earth like the geosphere, hydrosphere and atmosphere. In this, there should be the existance and the interaction of the living organism.
Here in the given model, there should be the human, fished, etc should be labeled as the biosphere rather than the atmosphere or without the atmosphere.
