Answer:
A. cells produce 2 daughter cells
Explanation:
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
ATP, also called adenosine triphosphate or the body's energy currency, is a compound that is synthesized when we have a compound called adenosine diphosphate (ADP). When this compound gets another phosphate group (P) attached, we get the more known ATP. This is also why the name changes from diphosphate to triphosphate (di - two, tri - three).
Answer:
A
Explanation:
Secretions from the liver and pancreas enters the small intestine through a segment of the intestine called the duodenum. The secretions aid in the final and complete digestion processes. The lipid digestion is aided in the small intestine through the secretions by emulsifying fats and completing necessary steps.
However B which contains segmental contractions is a peristaltic movement( found also in the oesophagus)isn’t peculiar to the small intestine. The large intestine also experiences this.
Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
Answer:
The correct option is: a. parotoid gland
Explanation:
Cane toads, also known as Bufo marinus or Rana marina Linnaeus, are the giant old species of the terrestrial true toads. The female cane toads are longer than the male cane toads.
The skin of the cane toad is highly toxic. An adult cane toad has large parotoid gland behind each eye, which secretes a milky-white toxic fluid called bufotoxin.
