For a species with a chromosome number of 2n=16, each cell has eight pairs of homologous chromosomes. There are not 32 chromosomes, 16 sets, or four chromosomes in a gamete.
In biology, the chromosome number 2n=16 indicates that the organism is diploid and has 16 total chromosomes, which are organized into 8 homologous pairs. So, the correct answer is option C) Each cell has eight homologous pairs. The number 16 (2n) represents the total number of chromosomes, not how many sets there are, making option B incorrect. One should not interpret this to mean there are 32 chromosomes in total, so option A is also incorrect. During S phase of the cell cycle DNA replication happens, but this doesn't change the number of chromosomes, just the number of DNA molecules, therefore, option D isn't right. Lastly, a gamete (sex cell) from this species would have n=8, or half the number of chromosomes, contradicting option E.

Answer:
Changes to Earth's radiative equilibrium that cause temperatures to rise or fall over decadal periods are called climate forcings.
Explanation:
Is this short enough?
Climate forcing is the process of affecting/changing the climate on the Earth through forcing factors.
These forcing factors are out of the climate system, and include things like volcanic eruptions, changing solar radiation levels, and changing levels of greenhouse gases in the atmosphere.
brain
motor neuron
glands
stimuli
Answer:
In the group of a brain, motor neuron, glands, and stimuli, the glands can be considered as an odd one out.
It is because the brain, motor neuron, and stimuli come under a common biological system which is termed as a nervous system.
A nervous system is a network or complex of nerve cells that perform the function of transmitting nerve impulses from one body part to another.
It consists of a brain, spinal cord, and different types of nerve cells (such as sensory nerves, motor nerves et cetera).
In contrast, a gland is defined as an organ of cells which synthesize and release chemical substances (such as hormones, enzymes et cetera) either into the bloodstream (endocrine glands) or into the body cavities (exocrine gland).
Thus, the gland can be considered as the odd one out.
Answer: There are literally countless single celled life forms all over the planet and every creature living is the descendant of single celled organisms. So the answer to your question as written is no, a cell can survive perfectly fine on its own, without the support of other cells, so long as its in a favorable environment.
Explanation:
Answer: No
Cells in bodies of living organisms are designed to help one another, so cells can not live/survive without support of other cells. They work in unity to help our body.
Hope this helps!
B.)The number of stomata is greater on the lower surface of the leaf.
C.)The number of stomata is equal on both surfaces of the leaf.
