Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.
Which of the following describes a negative feedback loop?
A. When the heart rate is too high, the body releases hormones that continually increase the heart rate higher.
B. When a pregnant woman is in labor, the body releases hormones that increase the intensity of contractions, which then increases the secretion of the same hormones.
C. When blood sugar concentration is above normal, the endocrine system releases hormones that lower the blood sugar concentration until it reaches a normal level, and the release of the hormones slows.
D. When a person is jogging, the body releases hormones that continually decrease the rate of oxygen supply to the legs.
ANSWER is A
When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

why would an athlete need to be concerned about a twitch or sustained contraction
Answer:
why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.
No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

Which animals are the main consumers of the Pan dropseed (Sporobolus ioclados) ?
Answer:
elephants
Explanation:
The animals that are the main consumers of the Pan dropseed are all animals have complex organ systems. Especially Seed-eating birds including American sparrows, and elephants.
What is Sporobolus ioclados?The grass family contains a nearly universal genus of plants called Sporobolus. The genus' members are frequently referred to as dropseeds or sacaton grasses.
They grow in numerous sorts of open habitat in warmer temperatures and are typical grassland and savanna plants. At least one species, as well as another, are endangered.
Only alkali sacaton has the little moth Bucculatrix sporobolella's caterpillar been discovered (Sporobolus airoides).
On Laysan Island, it appears that the local elimination of S. virginicus by feral rabbits led to the extinction of the Laysan dropseed noctuid moth (Hypena laysanensis).
All of the animals that eat the Pan dropseed most frequently have intricate organ systems, including seed-eating birds including American sparrows, and elephants
Thus, these are the animals that are the main consumers of the Pan dropseed.

The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.

Increase occur in high blood pressure, heart disease and stroke due to increase in sodium level in the blood. If the meal has no sodium then there is no increase occur in the sodium level in human blood while on the other hand, if the meal has more sodium then there is high increase in sodium level in human blood which causes high blood pressure, heart disease, and stroke.
