Answer:
It depends.
Explanation:
Often times, first-time mothers will not know what to do with their young and accidentally kill them.
Other times, birds will kill their young because the chicks fall ill, and the mothers do not want the sickness to spread to the rest of her chicks.
But for the most part, mothers will keep healthy young and try to keep them alive.
Hope this helps!
When an oncogene is turned on and is not balanced through suppression
of tumor suppressor gene, the normal
cells become cancerous and divides unregulated.
Normal cells differentiate while cancer cells do not. Additionally,
while normal cells respond to endocrine
and paracrine signals from neighboring cells, cancer
cells do not. Cancer cells have malfunctioned
apoptosis process due to a malfunctioned p53
tumor suppressor gene. Therefore they
continue to divide even when they have damage to their DNA. Cancer cells metastasize because, unlike normal cells, they do not produce an adhesive molecule that allows the cells to adhere to one another to form tissue.
A muscle is wrapped in epimysium and the muscle is composed of several fasicles, which is a fancy word for multiple muscle fibers wrapped in perimysium.
Answer:
yes your answer is correct
Explanation:
this is because the cells that fight against foreign materials are found in the blood
This is an example of balanced polymorphism. This occurs when the heterozygous individuals persist<span> in a population because homozygous individuals are less able to survive compared to the heterozygous individuals. In the case of </span>sickle-cell anemia, individuals with two copies of the β-globin sickle-cell allele develop sickle-cell disease and generally don't survive into adulthood, whereas individuals with one copy of the β-globin sickle-cell allele and one β-globin wild-type allele have functional red blood cells that are also resistant to malaria. We can expect this example of balanced polymorphism to occur in areas prone to malaria.
