Plate tectonics provide evidence for the theory of continental drift
One method is emphasized over all others, lateral breathing.
Mitosis is the division of the nucleolus and other vital organs found within the cell. Cytokinesis calls for the replication of DNA which is necessary before cell division can occur. In plant cells, the large central vacuole (not found in animal cells) must be evenly divided, which also occurs during mitosis. This process does not occur in animal cells, and instead lysosomes (only found in animal cells) must be evenly distributed among the two sister cells. So to summarize, the differences are related to the different organs found in plant and animal cells. Otherwise, everything else occurs as normal!
Answer:
The correct option is <u>less</u>.
Explanation:
outside an organism's body.
A hypotonic environment can be described as an environment in which the amount of solvent is more outside the cell as compared to the inside of the cell. The amount of solutes is more inside the cell. Hence, water tends to move inwards by osmosis in such an environment.
An isotonic environment can be described as an environment where the concentration of solutes and solvents is the same inside and outside of a cell.
When paramecium caudatum would be in a hypotonic environment, its contractile vacuole will be more active to pump the excess water. In an isotonic environment, there will be no or very less water for the paramecium to pump out of the body. Hence, contractile vacuole will be less active.
Answer:
25%
Explanation:
<u>Genotypes and phenotypes:</u>
- SS = straight hair
- CC= curly hair
- SC = wavy hair
- AA or A0= type A blood
- BB or B0= type B blood
- AB = type AB blood
- 00 = type 0 blood
A man with straight hair and A blood has the genotype SS AA or SS A0.
A woman with wavy hair and B blood has the genotype SC BB or SC B0.
Their first child has straight hair and O blood: SS 00
Because the child has type 0 blood, both parents must have a 0 allele, so their genotypes are SS A0 and SC B0.
<u>If their second child is a boy with straight hair, what is the probability that he has A blood?</u>
The hair and blood type genes are independent, so the hair phenotype of the child is irrelevant to determine the probability of him having A blood.
The parental cross for blood type is A0 x B0.
If you do a Punnett Square, you'll get the following offspring:
25% AB, 25% B0, 25% A0 and 25% 00.
The answer is the child has a probability of 25% of having A blood.
