Question

Are humans scavengers or consumers?

Solution 1

Id say scavengers but im not 100% sure

Solution 2

Actually, neither of them. Humans mostly don't hunt for prey and they do not eat just plants (except for vegans). They eat dead and proccessed food, so they are detritivores (detritophages), what means: "detritus eaters", (decomposing plant and animal parts). This is what I've learned on the lecture of famous Polish profesor January Weiner some time ago.

Question

The child of a short mother with black hair and a tall father with red hair is tall with black hair. This occurred because A) the parents provided some of the chromosomes. B) the parents and the child have identical nuclei. C) the child inherited chromosomes from both parents. D) the child inherited more chromosome from the father.

Solution 1

Answer: The correct answer is -

C) the child inherited chromosomes from both parents.

The child inherits 50% of the chromosomes from his father and other 50% from his mother (through fusion of male and female gametes that are sperm and egg respectively).

Due to this, child exhibits some of the paternal traits and some of the maternal traits. As per the given information in this question, mother is short with black hair and father is tall with red hair. The child produced is tall with black hairs. This also suggests that tall height and black hair are dominant traits (depicted by dominant gene variant) that suprress the expression of recessive trait (depicted by recessive gene variant), which are short height and red hairs.

Solution 2

Your answer is C. the child inherited chromosomes from both parents. Good luck with the rest of homework and have a merry 1/10/17!!

Question

In carnations, the allele for red pigmentation (R) is dominant to the allele for no pigmentation (r). Carnations with no pigmentation appear white in color. Help me asap!!! A cross between a red carnation and a white carnation produces pink carnations. Which of the following is true? This is an example of simple dominance. This is an example of incomplete dominance. The parent carnations are both homozygous dominant. The parent carnations are both homozygous recessive.

Solution 1

This is an example of incomplete dominance because neither R or W take completely over they both have equal Dominance to make a pink one.

Solution 2

I would have to say This is an example of incomplete dominance but i'm not sure if correct.

Question

Could someone please give me an example for this? I am very confused. Write down on example each for mutualism, commensalism, and parasitism from your own household. Your examples must represent relationships within your family unit. (ie: you and your parents, you and a sibling etc).

Solution 1

Basically mutualism, commensalism, and parasitism are forms of symbiosis. (the way animals interact with each other, usually referring to eating)

i don't think this can be associated with households, but an example might be:

mutualism - you need a MP3 player from your sister, but she needs you to do the dishes, etc...
commensalism- idk, maybe your grandma gives you free advice?
parasitism- you take money from your parents-lol.

Question

Answer:

Many genetic diseases would be curable.

Explanation:

study island be like

Solution 2

We would be able to chose what every kid looks like. Almost like picking a barbie. There will be no more flaws in society, because no one will give their kids flaws if they don't have to. However, this can also have some good effects with genetic sicknesses. This could be stopped. This would be a great advantage from human society
