Answer:
True.
Explanation:
In genetics, genetic similarities indicate the actual species. It also helps to identify the relationship or similarities between different species.
A physical character or structure can't be a measurement process of classifying any species as related to other species.
Such as Chimps is 90% genetically similar to human, but they not identical in physical appearance.
So, at present, scientists use genetic similarities between species to help classify them as related species, rather than focusing on physical or structure of any species.
Typically, a vacuole's job consists of isolating harmful materials, storing waste products, storing water in a plant cell, helping maintain the pressure within a cell, and exporting products out of the cell.
Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
Answer: d) lightheadedness or unconscious episodes.
Explanation:
There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:
1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.
2. The stage of resistance- this occurs till the stress is removed.
3. The stage of exhaustion
