Answer:
a. Yes. It is possible for them to produce a child with red-green colorblindness.
Explanation:
Color blindness is a change in vision that is characterized by the inability to distinguish some colors, especially green from red. Like hemophilia, color blindness is an example of inheritance linked to sex.
Color blindness is determined by an X-linked recessive gene, symbolized by Xd while the dominant allele gene, which conditions normal vision, is symbolized by XD.
Thus we can conclude that it is possible that the couple, exposed in the question, have a child with red-green color blindness. As the child's father already has the recessive gene, which is likely to be passed on to the child, if the mother also has the recessive gene for color blindness, the child is likely to develop red green color blindness.
The correct answer to this question is a: metamorphosis. Many
insects take on multiple forms through different parts of their lifecycle. For
example, many lepidopteran species (i.e., butterflies) include a caterpillar
juvenile stage. To reach the adult stage, the juvenile stage has to go through
metamorphosis, where its adult form is strikingly different from its juvenile
form.
The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
Plants living in dry areas face conflict.
EXPLANATION:
- Since they live in dry areas they will undergo more transpiration.
- If they open stomata during the day there will be excessive loss of water vapor that will result in their death.
- Therefore plants living in this area open the stomata during the night to obtain Carbon dioxide.
- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
I believe the child is demonstrating Animism.
Animism is belief in innumerable spiritual beings concerned with human affairs and capable of helping or harming human interests. It is a belief that all things have a spirit or soul, including animals, plants, rivers, mountains or feared or in some way attended to. Animists believe each animal is a powerful spirit that can help or hurt them and are to be worshipped or feared or attended to.
