Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

Explanation:
a. humans use sand, which is a nonrenewable resource to make glass -
<em>It's a renewable source</em>
b. Humans use coal, which is a renewable resource, to make charcoal for BBQ grills.
<em>It's a nonrenewable source</em>

The correct answer is Lysosome.
A membrane-bound organelle witnessed in various animal cells and the majority of plant cells is known as the lysosome. They are spherical vesicles, which comprises hydrolytic enzymes that can dissociate various types of biomolecules.
A lysosome exhibits a particular composition, of both its lumenal proteins and membrane proteins. The lysosome functions as the waste disposal system of the cell by digesting undesired substances in the cytoplasm, both from obsolete components within the cell and from external of the cell.
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi
