Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.

Examples are:  Onion, rhizome (ginger) and daffodil

Explanation:

There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.

Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.

Vegetative propagation can be done artificially also.

fredd [130]

Answer:

In the case study of the Chicago cyanide murder, the oxygen levels were very low which lead to the death of the cells in the body (there would be signs of dead cells in the victims' bodies).

Explanation:

The mitochondrion is the powerhouse of all cells in the animal body, it is responsible for cellular respiration and production of adenosine triphosphate or ATP.

When the cyanide stops the activities of the mitochondrion, each cell in the body begins to die as a result of hypoxia, which is a condition where the body or a part of the body is deprived of oxygen.

Legend has it that there was a less famous geneticist in the 1800s
NNADVOKAT [17]

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

  • The researcher has total control over the crosses.
  • Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
  • Pea plants may be examined for a greater series of generations than cats or other animals.
  • Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

  • The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
  • Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
  • Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

What happens in your body to cause you to get a fever?
andriy [413]

The presence of a fever is usually related to stimulation of the body's immune response. Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however. Amphetamine abuse and alcohol withdrawal can both elicit high temperatures, for example. And environmental fevers--such as those associated with heat stroke and related illnesses--can also occur.

The hypothalamus, which sits at the base of the brain, acts as the body's thermostat. It is triggered by floating biochemical substances called pyrogens, which flow from sites where the immune system has identified potential trouble to the hypothalamus via the bloodstream. Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever. Children typically get higher and quicker fevers, reflecting the effects of the pyrogens upon an inexperienced immune system.
