Answer:
1) give shape to cells lacking a cell wall;
2) allow for cell movement,e.g. , the crawling movement of white blood cells and amoebas or the contraction of muscle cells;
3) movement of organelles within the cell and endocytosis;
4) cell division
Explanation:
Answer: <u>Both parents are heterozygous carriers</u>.
Explanation: Since sickle cell disease is a recessive trait, it means the affected person will have "homozygous recessive" state of genotype only. Here parents are normal, which means they are carriers. So their genotype would be Ss, heterozygous.
Heterozygous parents only will have 25% chances of having their children affected.
Option 1 is incorrect, because if one parent has two recessive alleles, it means he/she is affected and this contradicts the situation mentioned in question.
Option 3 and 4 are incorrect because it is mentioned in question that both parents are normal.
The reason why Jane cannot receive blood from
her sister Mary is the blood type incompatibilities. <span>Jane has type A blood, so she has B antibodies.
Due to this, she can only receive blood from someone who is type A or type O</span> and it happens that Mary’s blood type is AB.
Answer:Both release carbon into the atmosphere, but burning fossil fuels releases CO2 at a much greater amount.
Both cellular respiration and combustion require a core fuel for the process to happen at all.
The chloroplasts would be unable to generate ATP
If the concentration of hydrogen ions (H+) outside of the thylakoids were equal to the concentration of H+ inside the thylakoids, the chloroplasts would be unable to generate ATP
Explanation:
As the high-energy electron from the reactive center of the photosystem conveyed from one protein to another in the protein transport chain of the chloroplast, the energy harnessed from the electron is used to pump H+ ions into the thylakoid lumen against concentration gradient.
The proton motive force created by having a high concentration of H+ ion in the thylakoid lumen than outside is to enable the creation of potential energy that is tapped by ATP synthase to create ATPs in a process called photophosphorylation. The ATPs made in this light stage is used in the anabolic process of the dark stage to make glucose through the reduction of CO2
