As a science student how to explain the cell division of non-science student ​
zhenek [66]

Explanation:

Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).

The Lincoln family has 3 children, 1 girl and 2 boys. What is the probability that their 4th child will be a boy?
goldfiish [28.3K]

Answer:

1/2

Explanation:

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl.

Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.

bezimeni [28]
The correct answer is "increased activity of the right hippocampal formation".
Hippocampus is a brain area which is part of the limbic system and is located below the cerebral cortex. Humans have two hippocampi, one in each side of the brain. Hippocampus is responsible for the formation of long-term memories, by participating in the consolidation of short-term to long-term memory. It also plays a very important role in spatial memory and orientation.
The task that this experienced cab-driver is asked to perform is related to spatial navigation and orientation abilities. The right hippocampus has been shown to participate in the formation of memory for locations in specific environments, while the left hippocampus has been shown to be involved in autobiographical and episodic memory. As a result, the PET scan will show an increased activity of the right hippocampus.

What is meant by the following statement about the cell membrane?
AysviL [449]

Answer:

The cell membrane is semipermeable because allows only certain molecules to pass through.

Explanation:

Semipermeability is a common property of cell membranes, due to their predominantly lipid composition, which gives them a hydrophobic character.

The cytoplasmic membrane is constituted by a double layer of lipids, in addition to structural proteins and glucides, which prevent the entry of polar or charged molecules. This characteristic allows lipids and small molecules without charge to pass freely through it.

Regarding the other options:

<em>     A. Cell membranes are associated with lysosomes, structures that contain enzymes. However, this characteristic is not related to semipermeability.</em>

<em>     C. They allow the passage of small molecules - devoid of charge - through them.</em>

<em>     D. Not all non-polar molecules pass through, as some need a transporter.</em>
