Answer:Genes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis unless they are separated by crossing over. Crossing over occurs when two homologous chromosomes exchange genetic material during meiosis I.
so true
Explanation:
In most animals, the diploid state of the life cycle is much larger than the haploid state.
<h3>What is life cycle?</h3>
The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.
The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.
During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.
For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.
Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

The cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.
<h3>What are cold-blooded animals?</h3>
Cold-blooded animals are those animals that are not able to regulate and maintain their internal body temperature when there is change in the external environment.
Example of cold-blooded animals are snakes and turtles. They expose themselves to sunlight to help them with their body metabolism.
Therefore, the cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.

Answer:
d. hyperthyroidism
Explanation:
Hyperthyroidism is a condition that occurs when the thyroid gland in our body secretes too much of the thyroxin hormone. Thyroid gland is a butterfly shaped gland that is located in our neck and it produces the hormone called thyroxin. Excess production of thyroxin leads to a condition named hyperthyroidism.
A person's metabolism increases when he or she is suffering from hyperthyroidism. One's weight is lost but the appetite increases. Other symptoms are extreme fatigue, irritability, heart palpitations, sweating and puffy eyes.
Thus in the context, Ms. Jones is suspect to have hyperthyroidism as she she is showing all the above symptoms.
We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms.
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:
1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.
2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.
3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.
Hope this helps!</span>
