DNA polymerase enzyme proofreads the DNA molecule to minimize errors during DNA replication.
DNA polymerase enzymes are the enzyme that carries out DNA replication. During this mechanism, a wide range of errors can occur. DNA polymerase read the nucleotide in the template strand and pairs it with the complimentary nucleotide, that is adenine to thymine and guanine to cytosine. But errors occur all the time during this pairing.
But DNA polymerase also carries out proofreading along with the formation of the strand. When an incorrect nucleotide is paired, the whole mechanism is arrested. DNA polymerase identifies the errors by detecting the variation in the 3' OH group. The strand formation is stopped, and the incorrect nucleotide is replaced by the correct one, only after that the process continues.
The errors during DNA replication are rectified either by Base excision repair or Nucleotide excision repair. These are carried out by DNA polymerase as well as DNA ligase enzymes
DNA replication and proofreading are undertaken by the same enzyme, DNA polymerase.

PLS HELP 20 PTS What other factors might cause individuals in this antelope herd to emigrate
Answer:
When you think about it - this is a similar case that happens in our species as well. You have groups of people who want to emigrate to different countries in hope for better grassland.
They emigrate but are immigrants from the perspective of the grassland where they will be.
The other factors that might cause individuals in this antelope herd to emigrate are immigration, increasing birth rate, and decreasing death rate.
What is emigration?When an animal emigrates, it's because its habitat is no longer ideal for it and it needs to move to a new location with a better habitat. Animals that migrate or emigrate never go back to the place they were originally from.
This is a similar situation to one that occurs in our species. There are various groups of people who want to immigrate to various nations in search of better grasslands. From the perspective of the grassland where they will be, they migrate but are immigrants.
Therefore, Immigration, a rising birth rate, and a declining death rate are some additional factors that could result in members of this antelope herd leaving the group.

Is the claim, "Despite not being a plant, you get your energy from the sun." accurate?
Write a paragraph explaining your reasoning.
Answer:
Yes (kind of), because even though we do not use the sun as directly as say plants, we still rely on the sun on a daily basis, however we don't necessarily get our energy from it, like plants do.
The sun produces light as well as heat, also known as solar energy. This makes it possible for life to exist on Earth, and we can use solar energy to power a wide variety of useful things, however sun/solar energy is not the only way to get electricity.
As we know, plants need sunlight to grow, although humans don't grow by being exposed to sunlight, sunlight helps grow plants which animals, including humans, need for food as well as oxygen they produce.
Most livestock we eat, cows for example, need plants to survive and many people eat meat, and even if you don't you'd eat plants which, once again, need sunlight to grow. Also, without heat from the sun, Earth would freeze.
OVERALL...
It's kind of like a chain, we get our energy from things that get their energy directly from sunlight. A short answer would be yes, but it's not quite as simple as that.
I hope this helps, hopefully you can use it to formulate an answer of some sort.

What is Mendel's law of segregation What do we called his factors today and where are they located?
The two alleles for a particular gene separate throughout the development of gametes, according to Mendel's law of segregation, leaving just one allele for each gamete. This indicates that just one allele from each parent is passed on to the offspring for a particular gene when the gametes combine at fertilization.
Mendel's factors have come to be known as genes. A gene is a section of DNA that contains the instructions for making a particular protein, which in turn defines a certain trait.
Chromosomes, which are situated in the nucleus of cells, are where genes are found. Each gene in diploid organisms like pea plants has two alleles, one of which is inherited from each parent.
Mendel's law of segregation explains Mendel's observed inheritance of single traits in his pea plants and it is the basis for Mendel's Punnett square, a tool that is widely used today to predict the possible outcomes of genetic crosses.

What happens to the light when you look at a green object?
When you look at a green object, the object reflects green light and absorbs other colors of the visible spectrum. The green light is then transmitted to your eye, where it is focused by the lens onto the retina.
The retina contains specialized cells called rods and cones that are sensitive to different wavelengths of light. The cones in the retina are responsible for color vision and are most sensitive to different colors in the visible spectrum, and when the green light reaches the cones, it triggers a neural signal that is sent to the brain, where it is interpreted as the color green. The absorbed light colors are not reflected and are green absorbed by the object, they are not transmitted to green the eye, so they are not perceived by the observer.

Why does an increase in number of cells cause growth?
Growth in all organisms occurs through the process of mitotic cell division. Cell division is the process of dividing old cells to form new cells, thereby increasing the number of cells needed for growth and various other activities in the body. It is a major and regular process essential to all life.
During mitosis, cells divide to form two identical daughter cells. All cells undergo mitosis and in this way the number of cells in the body increases and the organism grows.
Body tissue grows by increasing the number of cells that make it up. Cells in many tissues of the body divide and grow very rapidly into adulthood. As we grow, many cells mature and specialize in specific tasks in the body.

An organism can pass a gene mutation to its offspring if the mutation occurs in gamete as a result of sexual reproduction .
A mutation can be transmitted down to an organism's progeny if it happens in a germ-line cell (a cell that will develop into gametes, such as egg or sperm). This implies that the mutation will be present in each and every cell of the growing embryo. A parent's genetic mutation may be carried on to their child through their egg or sperm.
Throughout a human's life, these inherited mutations are prevalent in almost every cell of their body. Cystic fibrosis, haemophilia, and sickle cell disease are examples of hereditary mutations. Large-scale evolution only takes into account mutations that can be passed on to future generations. These are known as germ line mutations and they happen in reproductive cells such as eggs and sperm. Environmental factors contribute to mutations.

How can people exercise good and wise Dominion over the process of photosynthesis for God's glory
Wise dominion over the process of photosynthesis can be exercised in such a way that all the people and animals can benefit from it and we can use it correctly.
Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are formed by the reaction of carbon dioxide and water.
Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

What causes populations to lose genetic diversity due to chance?
Stochastic sampling error (i.e., genetic drift) causes populations to lose genetic diversity due to chance.
Genetic drift is a result of sampling error because individuals are randomly chosen when a population is sampled. A random selection is one in which each member of the population has an equal chance of being chosen.
The random change in allele frequencies caused by stochastic sampling of alleles from the previous generation is known as genetic drift (independent of demographic stochasticity).
The variety of various inherited features within a species is referred to as genetic diversity. There would be many people with a wide range of diverse traits in a species with significant genetic diversity. For a population to adapt to changing surroundings, genetic variety is essential.
