Answer: False
T-cells get their name from the endocrine gland (thymus) in which they are stored, not from the thyroid gland.
T cells<span> belong to a subtype of white blood cells known as "lymphocytes", that is why T cell are also known as T lymphocytes. The "T" stands for "thymus" -- the small endocrine gland in which these cells mature. It is responsible for a variety of other immune responses.</span>
The answer is genetic diversity, Genetic diversity is the
total number of genetic features in the genetic makeup of a species. It is well-known
from genetic variability, which defines the tendency of genetic characteristics
to vary. Genetic diversity serves as a way for populations to adapt to changing
environments.
Polar molecules (with +/- charges) are attracted to water molecules and are hydrophilic. Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic.
Answer:
Chloroplast
Explanation:
Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.
When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.
Thus, the chloroplast is the correct answer.
