Answer: C) 3
Explanation:
If you work through the punnet square for the two rabbits, only four of the sixteen possibilities has red eyes, and only three of those four has gray fur as well. So, three of the 16 rabbits have gray fur and red eyes.
I believe it is at the age of 6. Virtually all human behavior is governed by the brain. Experience that produces a change in behavior produces a change in the brain. Increase in Brain size. 25% of adult weight by birth, 50% of adult weight by 6 months, 75% of adult weight by 2 years, 90% of adult weight by 4-6 years, 95 % of adult weight by 6-7 years.
The answer is: from mother
In a human diploid somatic cell (2n), there are<span> in total 46 chromosomes</span> - 22 autosomal chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes. In males, there is one X and one Y chromosome (XY) while in females, there are two XX chromosomes (XY).
During the formation of gametes, a female could give only X chromosomes, so gametes from the mother contain one X chromosome. But, a male could give X or Y chromosome, so gametes from the father contain either X or Y chromosome.
Female gamete and male gamete fuse to form a zygote. Male zygote must contain both X and Y chromosome. It inherits Y chromosome only from the father, so X chromosome must be inherited from the mother.
I can think of why reason why other scientists would question this setup:
there are three salamanders each in each of the environments. This means that the salamanders which are in the different environment could learn some survival skills from the other salamanders, and the other scientists could argue that the result shows that learning skills of the salamanders, not their survival skills.
Autotrophs, by definition, are organisms that are able to internally manufacture their own food. Autotrophs, also known as producers, are organisms that obtain their energy by converting light energy into chemical energy, via photosynthesis. Photosynthesizing plants are an example of autotrophs.
Heterotrophs, by definition, are organisms that are unable to internally manufacture their own food. Heterotrophs, also known as consumers, are organisms that obtain their energy by consuming other organisms. Humans are an example of heterotrophs.
