Answer:
B
Explanation:
Heterozygous genotypes are those that have one dominant allele and one recessive allele.
Dominant alleles are represented as capital letters, while recessive alleles are represented as lowercase letters. So, a heterozygote should have one capital letter and one lowercase letter.
Looking at the answer choices, only B fits this, so it's the answer.
Hope this helps!
The DNA replication occurs by preparing a new strand of DNA that is based on the template strand only. So understanding the nitrogen base pairing is very essential for understanding DNA replication.
<h3><u>
Explanation:</u></h3>
DNA replication occurs prior to any type of cell division in all organisms. In case of humans, the DNA that is to be replicated needs to be de winded by means of decondensation of chromosomes into chromatin fibres and then to DNA fibres. Then there are enzymes like helicase and gyrase which helps in breaking the hydrogen bonds between two strands of DNA and to open it up for enzymes to get attached.
Then the enzyme DNA dependent DNA polymerase works on both the strands of DNA where it reads the mother DNA strand as a template and then brings deoxyribonucleotides complementary to the template strand and then polymerises it with the previous nucleotide to form a new DNA strand. Thus two DNA strands are produced which are again complementary to each other, leading to the production of a new daughter DNA. So, understanding the complementary base pairing is very essential to understand the DNA replication.
Answer: Like us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. ... As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.
I don't know what your question is but if you're wondering what is called when water changes from a gas to a liquid phase the answer would be Condensation
