Answer:
actively pump water back into their cells to counter its loss due to osmosis
Explanation:
- When an organism actively regulates the osmotic pressure of the bodily fluids present in the body in order to maintain homeostasis in the body then this is termed as osmoregulation.
- Since, the Great salt lake in Utah has a lot of salt in it, the water content in the surroundings of the brine shrimp is much less and hence, the water will move out of the brine shrimp's body as osmosis causes the movement of the water from higher concentration of water to lower concentration of water.
- However, movement of water out from shrimp's body would cause it to desiccate and hence, it must have an actively pumping system that pumps the water back into their cells in order to compensate for the water lost due to osmosis.
B because the temperature goes up then the birds would move to the south were it is cooler.
Answer: The action of a neurotransmitter at the postsynaptic cell is terminated by the following: enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
Explanation: After a neurotransmitter has bound to its receptor on the postsynaptic membrane and triggered a biological response, in order to avoid over stimulation of the receptors, the neurotransmitter is either degraded by specific enzymes or taken back to the presynaptic cell into the synaptic vesicles by action of specific transporters. This mechanism is to maintain a balance (homeostasis).
Answer: The genotype of the parents are BB and WW while the genotype of the offsprings is BW.
The phenotype of the parents is: black for the homozygous black bird and white for the homozygous white bird. The phenotype of all the offsprings is bluish gray
Explanation: From the information provided, black trait B and white trait W are homozygous therefore the genotype of the parent are BB and WW for the black and white bird respectively. Their phenotype is black because the black trait B is dominant and white because the white trait W is also dominant.
See the attached punnet for the cross between the two birds.
Answer;
A. Alice carried the recessive allele
Explanation;
-Hemophilia is an inherited bleeding disorder in which one lacks or have low levels of clotting factors. This keeps the blood from clotting. It is inherited as an X-linked recessive trait.
-X-linked recessive genetic disorders are conditions caused by an abnormal gene on the X chromosome. Females who have a disease gene present on one of their X chromosomes are “carriers” for that disorder. Carrier females usually do not display symptoms of the disorder because they have another copy of the gene that can usually compensate for the copy with the disease-causing change or mutation.
-A male has only one X chromosome and, if he inherits an X chromosome that contains a disease-causing gene, he will develop the disease. Males with X-linked disorders pass the disease gene to all of their daughters, who will be carriers if the other X chromosome from their mother is normal.
