Answer:
In chronic hypertension the baroreceptors get used to high blood pressure and does not respond effeciently.
Explanation:
Hypertension is the condition when blood pressure usually remains higher than normal. The systolic higher blood pressure is considered high above from 139 (mmHg) and diastolic is considered as above from 89 (mmHg).
The condition is considered to be chronic when it affects vital organs such as lung and hurt. There are several stimuli to which brain response to maintain normal blood pressure. Most important and fast of these is baroreceptors present in blood vessels that detect the change in blood pressure and signal to brain for proper response such as dilating the blood vessels in case of high blood pressure.
In coronary hypertension the walls of blood vessels become stiffer due to several factors such as smoking, stress and ageing. The high blood pressure produces tension in the wall of artery which is detected by baroreceptor. In coronary hypertension these barorecepetors get used to higher blood pressure thus does not response to it properly. So blood pressure remains high.
The best answer is Neoproterozoic era. Neoproterozoic Era is the unit geologic time from 1000 to 541 million years ago. It is the last era of the Precambrian Supereon and the Proterozoic Eon; it is subdivided into the Tonian, Cryogenian, and Ediacaran Periods. It is preceded by the Mesoproterozoic era and succeeded by the Paleozoic era.
Answer:
The given statement is false.
Explanation:
The lateral gene transfer of the horizontal gene transfer refers to the movement of the genetic substance between the multicellular and unicellular organisms other than by the vertical transmission of DNA to the offspring from the parent. Horizontal gene transfer is essential for evolution in several organisms. The mechanism is common among the prokaryotes like bacteria and is accountable for bacterial drug resistance.
On the evaluation of certain sequences of DNA, it has come to know that horizontal gene transfer also takes place in eukaryotes from the mitochondrial and chloroplast genomes to the nuclear genome. One of the examples is that plants possess the tendency of getting genetic information from viruses.
Answer:
Las interacciones interespecíficas son determinantes importantes de la dinámica de la población y la estructura del paisaje puede influir en estas interacciones. Todas las especies interactúan con depredadores, parásitos, competidores, etc., como parte biótica de su entorno.
