Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.

<h2>Answer:</h2>
The statement that most directly explain this concept is "nitrifying bacteria that convert ammonia into nitrites and nitrates are found in the soil".
<h2>Explanation:</h2>
Bacteria living in the soil in root nodules of various plants are directly involved in the nitrogen cycle. The nitrifying bacteria "<em>Nitrobacters" </em>and "<em>Nitrosomonas"</em> can fix atmospheric nitrogen and can convert it into nitrates and nitrites. As plants can not directly fix that atmospheric nitrogen so these <em>Nitrobacters</em> and <em>Nitrosomonas </em>who lives in symbiotic relation in their root nodules do this nitrogen fixation for them. So these bacteria provide them nitrates and nitrates that plants can directly uptake and can use in their essential metabolic cycles. In this way, Geosphere plays a critical role in nitrogen fixation.
Answer: <u>Option C
</u>
Animals moving in packs or flocks, try to utilize the energy efficiently. The same case is with birds moving in V shape. They use the energy of the air around them, so that air pressure could help them fly with less input of energy. V shape pattern is more aerodynamically energy efficient.
Also, while flying there are no chances of finding mates for reproduction, so option A and B are incorrect.
