This is known as the Cambrian Period.
Answer:
1. True
2. Option 4
3. Option 2
Explanation:
1. Forest interiors are region that show no sign of detectable edge influence and their condition is determined by using samples from un-fragmented forest from which the influenced forest edges are removed. Hence, the given statement is true
2. The smaller patch size of a place or landscape has more fragmentation issues. Hence, Option 4 is correct
3. Option 2
The initial extinction cascades that arises among the plant species first is then also
affect other species such as animal in a given habitat. This effect is known as domino effect. In forest fragmentation, plant biomass is lost and the species dependent on this biomass is also adversely affected.
<h2>Pentose phosphate pathway</h2>
Explanation:
- Ten days after an injury, there is still cellular and tissue repair going on. Glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase are two enzymes involved in the pentose phosphate pathway which are also found in abundance in neutrophils and macrophages. These phagocytic cells of the immune system utilize NADPH to generate superoxide radicals from molecular oxygen, which are used to kill the pathogens or damaged cells they have ingested. The great rise in these two enzymes could be coming from these immune cells as they are cleaning up the damaged tissue.
- Additionally, these immune cells use these two enzymes to produce NADPH, which can be used to counterbalance oxidative stress via the action of the glutathione system. Injured tissue can cause oxidative stress and increase the need for action from the glutathione system.
- The glycolytic enzyme activity would be decreased as some of the glucose is shunted to the pentose phosphate pathway to favor tissue repair over the ATP generation which comes from the glycolytic pathway reactions.
Answer:
Gravity
Explanation:
Gravity keeps things together. Think of it in 2 ways:
1.Without gravity, an Earth-orbiting satellite would go off into space along a straight line. With gravity, it is pulled back toward Earth.
2.Gravity keeps the earth round, pushing it on all sides, which is what gives it its round shape.
Hope it helps!! =D
