Answer:
The correct answer would be elongation.
Cell elongation is defined as the lengthening of a cell during differentiation of a cell. It takes place during growth of an organism or during movement in mature plants.
In plants, it is primarily regulated by light and plant hormones like auxin.
Auxin modifies the structure of the cell wall which helps the cell to elongate.

We can’t use nitrogen from the air and that’s why we have to use bacteria to into something that we can use
Answer:
a, 8
b, 3
Explanation:
If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
Answer:
A) a cow who's coat color is roan (red and white) : Co- dominance
B) A red flower and a white flower produce a pink flower: Incomplete dominance
C) In rabbits there are 4 different versions of the gene for coat color- Multiple alleles
Explanation:
Co-dominance can be described as a phenomenon in which the two different phenotypes of the parents can be seen in the offspring produced by them. For example, In the option A, the cow had a parent with red coat colour and a parent with a white coat colour. Both these traits were seen in the offspring.
Incomplete dominance is a phenomenon in which parents of two different phenotypes give rise to a new phenotype in the offspring which is not present in both of the parents.
