b
Explain why viruses are not considered to be living.
viruses are not considered to be living because they lack cells and cannot reproduce on their own. although viruses contain DNA, they do not have a cell membrane, cytoplasm, ribosomes, or other organelles. they also need to use the cells of living organisms in order to replicate.
The feature that helps organisms survive better in its environment is adaptations.
Answer:
c. Acclimatization
Explanation:
<u>Acclimatization</u> : Various physiological readjustments and compensatory mechanisms in body that reduces the effects of hypoxia in permanent residents at high altitude. These are basically the respiratory and hematopoetic adjustments to long-term move to high altitude.
As the Chum Salmon (oncorhynchus keta) are born in freshwater water constantly diffuses into the body and ions are lost from the body while in the sea water, they lose water.
As alot of changes are occrun in the cells of the gills of chum salmon, that is acclimatization as various physiological readjustments are being made.
Explanation:
Incomplete dominance is an intermediate effect of the dominance where the allele for a trait does not express its complete effect of a paired allele as a result both the alleles show their equal effect on the trait.
The generations are produced having a third trait as observed in the case of snapdragon flowers. In the case of flowers
The allele which
1. Determines the red color will be- R
2. Determines the white color will be- r
The monohybrid cross will have parents with genotypes:
1. Red flower- RR
2. white flower-rr
The F₁ generation will have offsprings with genotype-
RR X rr = Rr (Pink flower)
The F₂ generation will have offsprings with-
Rr x Rr= RR, Rr and rr.
