Answer: All of these are true (besides the one that says that none are true...).
Explanation:
The ecological succession is a slow change in the living community of the ecosystem along with the changes occurring in the non-living environment until the ecosystem attains stability.
The primary succession can be defined as the initial level of succession. This succession begins in the primitive environment. The soil develops after the weathering process of rocks.
The secondary succession begins in the region where life forms existed before and the area begin damaged by the catostrophic event like forest fire, earthquake and other type of calamities. Some remaining plant parts can give birth to the entire colony of plants.
<span>The plant is called a
lycophyte. Lycophytes are plants that are similar to ferns. This plants does
not have fruits, flowers, and seeds. Lycophytes are reproducted by wind
pollination. The leaves of lycophytes are called microphyllis which consist of
one vein. </span>
Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
The end products of aerobic respiration are carbon dioxide, water, and energy. The end products of anaerobic respiration are acids, alcohols, gases, and energy. Explanation: Glycolysis is the common process occurs in both aerobic and anaerobic respiration.
Gastroileal reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum.
The gastroileal reflex is triggered by the presence of food in the stomach as well as gastric peristalsis.
Gastroileal reflex brings about peristalsis in the ileum as well as the opening of the ileocecal valve, which in turn facilitates the emptying of the ileal constituents into the large intestine or colon.
The gastroileal reflex is one among the three extrinsic reflexes of the gastrointestinal tract. The other two include the gastrocolic reflex as well as the enterogastric reflex.
This type of gastrointestinal reflex is moderated by the vagus nerve and gastrin.

Answer:
Which of the following is not part of the nucleotide structure?
a.
<h2>
Sulfate backbone </h2>
c.
Phosphate group
b.
Nitrogenous base
d.
5-carbon sugar
Explanation:
A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
