A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
Pollution adds heat to the air. for example: gas and smoke from cars and trucks etc. climate change will be affected because the heat will cause the weather and atmosphere around to get hotter. clearing pollution will keep the air cleaner.
<h2><u>Answer:</u></h2>
The 4 principle requirements for microorganisms survival are:
1) Food
2) Moisture
3) Warmth
4) Time
There are microscopic organisms that can develop in cold temperatures and some that blossom with warm temperatures.
A few bacteria go after the other microscopic organisms for survival. Different microscopic organisms get by getting supplements from dead items. Some microorganisms use photosynthesis to make their nourishment.
Answer:
The correct answer is - 2n = 41 chromosomes.
Explanation:
It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -
Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).
Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)
19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.
Answer:
Anther
Explanation:
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.
Anther: The part of the stamen where pollen is produced.
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
