The correct answer is plants
I think its an element but i could be wrong
Answer:
A) series of events that cells go through as they grow and divide
Explanation:
Cell cycle refers to the sequential events which take place during the division of one parent cell to daughter cells.
Since the cell divides continuously in the multicellular organism therefore these events are repeated over and over again that is the same steps are repeated a thus is known as cyclic events.
The cell cycle takes place into two phases: the interphase during which the cell prepares itself for nuclear division and the karyokinesis during which the nucleus divides.
Thus, Option-A is correct.
Answer:
Gills are an immediate tip for you to know that this animal lives in an aquatic biome, where it will be using its gills to breathe underwater without the need to surface for air. Usually, the animals with gills are fish, because they filter out oxygen from the wanter they inhale.
Explanation:
Answer:
The correct answer is option D) Albino = recessive, black = dominant.
Explanation:
- According to Mendel's Law of Dominance, of the two alleles which represent a gene, one can express itself even when in the presence of the other allele, that is in heterozygous state. This is called the Dominant allele. The other allele can express itself only in homozygous state. This is called the Recessive Allele.
- When a black guinea pig is crossed with an albino guinea pig, all black offspring (5) are obtained in the F1 generation.
- This indicates that the Black colour is dominant over the albino colour, as it masks the expressions of the albino phenotype.
- This also indicates that the genotype of the parent black guinea pig is homozygous dominant, as if it would have been heterozygous dominant then in the F1 generation there was a chance of formation of both black and albino offspring in 1 : 1 ratio.
- When a black guinea pig from the F1 generation is crossed with the albino guinea pig it gives both black (4) and albino (3) guinea pigs, roughly in the 1 : 1 ratio.
- This indicates that black guinea pig from the F1 generation was heterozygous dominant. This is why the recessive allele giving rise to the albino phenotype could express itself in the second cross.
- The second cross between F1 offspring and recessive parent is called the Test Cross.
