Natural selection acts directly on those gene variations for traits or phenotypes.
The phenotype of an organism is the physical characteristic and is determined by the organism's genotype. Natural selection selects the genes that produce a certain phenotype by providing suitable conditions for a certain phenotype.
Answer:
CFTR protein is found in the cells lining the lungs
Answer:
b. cladophora
Explanation:
The cladophora algae is a type of green algae that grows attached to rocks or wood that are underwater. It forms short, rigid green filaments that branch, it's smell is similar to mushrooms. The cladophora is introduced in aquariums via contaminated plants or equipment, therefore to prevent it's formation it is necessary to clean everything before intoruducing it to the aquearium. This algae is so resistant once installed that usually the tank has to be re-started.
Answer:
Explanation:
Transfer RNA (tRNA) precursors undergo endoribonucleolytic processing of their 5' and 3' ends. 5' cleavage of the precursor transcript is performed by ribonuclease P (RNase P). While in most organisms RNase P is a ribonucleoprotein that harbors a catalytically active RNA component, human mitochondria and the chloroplasts (plastids) and mitochondria
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.
