Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

<u><em>Boreal forest
</em></u><em> is a large amount of carbon is being taken in by Biome</em>
Answer: C. Boreal forest
Explanation:
BOREAS is the investigation completed in the boreal woodland at Canada that spotlights on improving our comprehension of the radiant energy, heat, water, carbon dioxide and gases between the boreal forest and the environment.
An essential goal of BOREAS was to gather the information expected to improve the models of computer simulation of the significant procedures controlling these exchanges with the goal that researchers can envision the impacts of worldwide change on the biome.
<span>B.The existence of vestigial structures
</span>
Vestigial structures have been used for long by evolutionists to support the theory of evolution. These organs are believed to have been in use in the past lives but as the species adapts to new forms of life and lifestyle,the vestige organs becomes obsolete,but are not removed by the body. An example of vestige organs in human being are the appendix,tail bone,and mammalian grands in men.

Accumulation of substances such as pesticides or other chemicals in an organism
Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
