Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
Chromosomes are the homologous chromosomes that cross over
Answer:
The correct answer would be c. The cell has a greater level of structural support.
Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.
They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.
- Lipid bilayer gives the rigidity or shape to the cell.
- It isolates the cell from the sorroundings.
- It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
- Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.
Hence, most appropriate choice would be c. The cell has a greater level of structural support.
An extinction event is a well-known
and quick decrease in the biodiversity on Earth. Such an occurrence
is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the
rate of extinction surges with respect to the rate of speciation.
In other words, this happens when species cannot adapt generally to the change
in the environment. So the correct answer would be letter a.
Answer: El Niño is a part of a routine climate pattern that occurs when sea surface temperatures in the tropical Pacific Ocean rise to above-normal levels for an extended period of time.
