DNA Damage: Causes and Effects
The most significant consequence of oxidative stress in the body is thought to be damage to DNA. DNA may be modified in a variety of ways, which can ultimately lead to mutations and genomic instability. This could result in the development of a variety of cancers including colon, breast, and prostate. Here we discuss the various types of damage to DNA, including oxidative damage, hydrolytic damage, DNA strand breaks, and others.

A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.

Answers

Answer:

B

Explanation:

Cause I say so

The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.

What is Population?

A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.

According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.

Therefore, the correct option for this question is A.

How does the carnivorous plant catch its victums?

Answers

Pitfall traps (pitcher plants) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria. Flypaper traps use a sticky mucilage. Snap traps utilise rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum.

Answer:

They use special traps that are connected to them.

Explanation:

For example, the Venus Flytrap uses it's "mouth" to close on the fly. A sundew plant uses sticky spines to stuck to the bugs and slowly curls up and digests the bug.

population II stars

red dwarf stars

population I stars

brown dwarf stars

Answers

Answer:

population I stars.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.

A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

What conditions are necessary for rocks to melt?

Answers

Answer:

In explanation.

Explanation:

The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).

The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.

What is the effect of temperature on different substances?

Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.  

Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.
