When would a point mutation occur?
It can occur before and after cell division
Before the cell divides
After the cell divides
Before DNA replication
Answer:
The correct answer is option 1. Before and After Cell Division
Explanation:
Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations. But they may also occur after as well as before the division of a cell.

The abundance of sodium leak channels in skeletal muscle is ______ the abundance of sodium leak channels in a typical neuron.
The abundance of sodium channels in muscles is as important as the abundance of sodium leak channels in a typical neuron.
Sodium plays an essential role in the body, this includes important functions such as:
Intervening in the process of muscular contraction.Intervening in the process of interneural communication.This is possible through sodium channels in cells that allow sodium to enter or leave the cell at very specific times and this causes specific reactions in cells.
In neurons: Sodium channels are abundant and essential because due to the action of sodium signals are passed from one neuron to others.In muscles: Sodium channels are abundant and essential, especially in skeletal muscles. The role is sodium is to contract or relax muscles, which makes movement possible.Based on this, the presence of these channels in both neurons and skeletal muscles is equally important.

differences between the structure of the wall of the stomach and the structure of the wall of the ileum
Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

the sequence of events that produces another generation of organisms.
The sequence of events which produces another generation of organisms is called as the Life cycle.
What is Life cycle?Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.
In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.
Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

A. this releases energy from a bond by breaking it and ending with
low-energy products
B. this creates bonds that have absorbed energy from its
surroundings and created energy-rich products
C. this rearranges the shape of a molecule to fit into a protein
better
This creates bonds that have absorbed energy from its surroundings and created energy-rich products.
Describes an endergonic reaction?An endergonic reaction is a type of reaction that requires free energy to proceed. An example of an endergonic reaction is photosynthesis because the reaction uses solar energy.
So we can conclude that this creates bonds that have absorbed energy from its surroundings and created energy-rich products.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide
