Answer:
Comparison between the growth process and life cycle of plants and animals:
A single cell is enough to initiate life in plants and animals. The cells of both the plants and animals multiply to increase their number. The gametes in animals and the plants that produce flower, shows sexual reproduction and are haploid in nature. The egg and sperm of animal is similar in function with the megaspore and microspore of plants.
Differences between the growth process and life cycle of plants and animals:
The fertilization of plants depends on other animals ( like bees and bird) but the animal fertilization does not depends on other organisms. Well developed parental care is present in animals but absent in plants. The growth of most plants includes the alternation of generation whereas limited animals shows alternation of generation.
Share a common ancestor, process of elimination
Answer:
B is correct
Explanation:
This is because in DNA, purines (A and G), pair with pyrimidines (C and T), and more specifically, adenine pairs with thymine and cytosine pairs with guanine. Per this base pairing, B should be the right answer.
Answer:
Dominant
Explanation:
Let the allele for short tail trait be represented by "T" and allele for long tail trait be represented by "t"
When a short tailed mutant with genotype "tt" is mated with long tailed mouse, following offspring will be produced -
Tt * tt
Tt, Tt, tt, tt
so the ratio of short tailed and long tailed mouse is 1:1
Here it is given as 4:3 . Hence, there are chances that short tail trait is dominant
In the second generation , two short tailed mouse are crossed. The following offspring will be produced
Tt * Tt
TT, Tt, Tt, tt
The ration of short tailed and long tailed mouse is 3:1
Here it is given as 6:3 i.e 2:1 . Hence, short tail trait is dominant over long tail trait.
<span>It isn't genuine that in
both gametogenesis occasions, which is known to be spermatogenesis in guys and
oogenesis in females, may include meiosis with a similar number of gametes
delivered when finished. Gametogenesis is known to be a procedure in which
cells experience meiosis to shape gametes.</span>
