Answer:
If both parents do not have sickle-cell anemia, than the possibility is low.
Explanation:
If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.
If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.
When both parents have sickle cell anemia, their child will definitely have it.
Answer:
No, 0% chance
Explanation:
none of the parents are carriers of this disease, and are homozygous dominant to the normal red blood cells, so they will not inherit this disease
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration.
Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.
Answer:
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
Explanation:
Osmosis refers to the movement of water molecules through a selectively permeable membrane. The movement always occurs from the region of higher concentration of water to that of lower concentration. Osmosis does not include the movement of solutes.
Diffusion is the movement of substances from higher to lower concentration region. Diffusion is not restricted to movement of water only.
The type of DNA in each cell controls the rate of the cell cycle and the specific type of cells
formed
The size of the cell determines the number of cells that will be produced from each cycle.
Internal and external signals regulate the progression of the cell cycle at various critical
checkpoints
Hormones signal the start of the cell cycle, and DNA determines how the cell differentiates.
Answer:
The correct answer is internal and external signals regulate the progression of the cell cycle at various critical check points.
Explanation:
The cyclic event that helps to prepare the cell for division is termed as cell cycle.Cell cycle are regulated by various internal and external factors which regulates the passage of cell through various critical check point.
For example Maturation promoting factor helps in the progression of frog egg oocytes cells from G2 to M phase.
G1 cyclin CDK helps in the passage of cell from G1 to S phase.
Decomposers are able to break down this material and release carbon back into the atmosphere and the cycle can begin again. Without decomposers, the carbon would remain locked in dead organisms and could only be released through combustion.
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
The phosphorous cycle does not enter the atmosphere, unlike the nitrogen cycle and the carbon cycle" is the way the phosphorous cycle differ from the nitrogen cycle and the carbon cycle.
The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle.
Therefore, Decomposers are able to break down this material and release carbon back into the atmosphere and the cycle can begin again.
