The correct answer is option A, a zygote

Reason -

A zygote (single diploid cell) divides over a period of three week time period and transforms into a larva. An embryo goes through the phases of stages like cleavage, gastrulation, neurulation and organogenesis. A larva transforms through the process of metamorphosis to develop into an adult drastic changes.  

The entire process of development is as follows – .  

Eggs, zygote, larva and then into an adult

Chargaff's Rule. If there is 20% Adenine in the cell, what is the percentage of Thymine, Guanine, and Cytosine found in the same
Ulleksa [173]

Answer:

A= 20%

G= 30%

T= 20%

C= 30%

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.

Then, 20% + 20% + C + G = 100%

40% + C + G = 100%

C + G = 100% - 40% = 60%

So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%

Finally, A= 20%; G= 30%; T= 20%; C= 30%

Two-component regulatory systems rely on a balance of phosphorylation and dephosphorylation of sensor kinases and response regul
otez555 [7]

Answer:

The correct answer is the first statement.

Explanation:

A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.  

In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.
