Explanation:
maybe next time put answer choices to be able to help u better... :)
Answer:
Mechanical incompatibility.
Explanation:
Mechanical incompatibility: occurs when species cannot mate because their reproductive structures are incompatible – In animals with internal fertilization, male and female sexual organs may not fit together – For example, snails of species whose shells have left-handed spirals may be unable to copulate successfully.
Mechanical incompatibility of male and female genitalia is common in animals with internal fertilization. However, our knowledge regarding the precise mechanisms is limited.
The answer is C. The moon is to the side of Earth and the Sun.
Hope this helps!! :3
Answer:
Deep Brain Stimulation (DBS)
Depression, Uncoordinated body movements such as in Parkinson's disease
Explanation:
Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.
This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.
The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.
Answer:
Explanation:
a)Organ transplantation requires that the donor organism and recipient be genetically close so that the graft or transplant will not be attacked by the immune system of the recipient leading to rejection and damage. Squeaky is likely to be made up of a different genetic configuration compared to laboratory inbred FG426 mouse
b) ips (induced pluripotent stem cell) on the other hand can benefit squeaky since the cells are somatic cells such as B cells, Keratinocytes, neuronal progenitors cells, kidney and muscles gotten from the donor that are reprogrammed by reactivating silent genes through fusing of another different cell such as ES (embryonic stem cell) and introduction of some transcriptional factors such oct4, sox2,kf4, and k-myc leading to transcriptional activity and DNA methylation. This induced pluripotent stem cells can be grown into organ that can be transplanted to the recipient who was initially the donor of the reprogrammed somatic cells. Because it is from the host, the transplanted organ is not likely to trigger immune response compare to those grown from ES from other bred.
