There is a dominant trait that affects the short arm of chromosome #4 known as Huntington's disease. A woman that is heterozygous for Huntington's disease and a normal, unaffected male have a female child. What is the probability that this child may be affected by the disease?
Answers
Answer: 50%
Because there are different systems in the body to prevent diseases, however chromosome diseases are usually hereditary so there is about a 50% chance that the child may be affected by this disease.
Huntington's disease is a dominant chromosomal disorder, when a woman who is heterozygous marries a man who is normal, then the probability for the child to be affected is 50%.
What is Huntington's disease?Huntington's disease is a rare genetic disease which causes the progressive breakdown of neurons present in the brain. Huntington's disease has a wide impact on a person's functional abilities and results in movement, cognitive thinking and psychiatric disorders.
When a woman who is heterozygous (Hh) for Huntington's disease marries a man who is normal (hh) for the disease, the probability of the offspring to be affected with the disease can be calculated with the help of Punnett square. And, it will be 50%.
The Punnett square is attached with the answer.

How much dna is in each nucleus of each cell
Answers
Answer: Look below =3
Explanation: That makes a total of 6 billion base pairs of DNA per cell. Because each base pair is around 0.34 nanometers long (a nanometer is one-billionth of a meter), each diploid cell therefore contains about 2 meters of DNA [(0.34 × 10-9) × (6 × 109)].
Each cell has 1 DNA. When it is mitosis, a piece of DNA breaks down into thing called chromosome.

The animal-like parasite plasmodium causes the disease
Answers
Answer:
Malaria is the answer
Explanation:
The animal-like parasite plasmodium causes diseases like malaria.
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in a serious and occasionally fatal disease known as malaria.
An obligatory parasite of insects and vertebrates, Plasmodium is a genus of unicellular eukaryotes. The parasite Plasmodium, which causes malaria, is spread via the bite of an infected mosquito.
Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Through the bites of female Anopheles mosquitoes carrying the parasites that cause malaria, people can contract this potentially fatal illness. It can be avoided and treated.
Therefore, malaria is brought on by the parasite plasmodium, which resembles an animal.

What is Developmental biology?Developmental biology is the branch of science which deals with the study of the process through which an organism such as an animal and a plant grows through and develops with respect to time to more evolved organisms.
Developmental biology includes the biology of regeneration, asexual reproduction of an organism, metamorphosis, and also the growth and differentiation of the stem cells which take place in the adult organisms.
Development of species accomplishes two major objectives which generates cellular diversity as well as the order within each generation, and it also ensures the continuity of life from one generation to the next generation.
