Answer:
A "Pacemaker" can be external or internal and usually generates electrical stimuli to the heart muscle with anelectrode.
Explanation:
Pacemakers allow you to perceive when the heart is beating irregularly or very slowly. This small device sends an electrical signal or electrical impulses to the heart, which makes it beat at the normal rate, because the electrical impulses are transmitted to the heart muscle; by means of an electrode that connects the device with the heart muscle functionally thus an adequate functionality of the heart.
The pacemaker is able to detect heartbeat failures and, at that time, sends an electrical signal through the wires (electrodes) so that the heart contracts.Pacemakers may have more than one electrode depending on the number of areas of the heart that we need to stimulate.
b. All female offspring inherit their mother's mitochondria, and therefore the same mitochondrial DNA.
c. As a result, all female family members that share a maternal lineage would have the same mitochondrial DNA.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
e. All offspring inherit their father's mitochondria, and therefore the same mitochondrial DNA.
Answer:
a. Mitochondrial DNA is inherited through the maternal lineage.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
Explanation:
DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.
Lake and ponds are standing water.
Further Explanation:
Wetlands are the areas of marsh, peatland or water. It can be natural or artificial, permanent or temporary with water; static or flowing.
The characteristics of wetlands are-:
1. An abundance of water and prolonged saturation of the same.
2. Wetland vegetation have special adaptation for life in permanently or seasonally saturated soils.
3. The saturated soil forms distinct and visible characteristics.
Wetlands are often found alongside the waterways and also in floodplains. Wetlands may vary widely due to difference in soil, topography , the chemistry of water and vegetation. Several smaller wetland types may give rise to large wetlands.
Many wetlands found in rocky mountains regions dry up.
Lake and ponds: The characteristics feature are:
Ponds are shallow enough to allow the growth of plants across entire surface. The area where plants can grow is known as photic zone. In contrast to ponds the lakes has aphotic zone.
