Through genetic engineering, genes from one species can be introduced into another that is unrelated. The individuals involved in selective breeding must be of the same species.
In GMO, researchers combine new gene combinations. Genes come together on their own during selective breeding. By utilizing pollen from one strain to fertilize another strain and therefore "cross" the gene pools, for instance, selective breeding can change a species' genetic makeup naturally.
The chromosomes are altered intentionally through genetic engineering—a technique that is against nature. For instance, a crop may contain a gene from a cold-water fish to prevent freezing during the winter. This wouldn't happen in the wild.

What assumption do we make about an isolated bacterial colony that formed on an agar plate?
When an isolated bacterial colony is discovered on an agar plate, there are a few assumptions that are typically made.
Firstly, it is assumed that the bacteria are a single species, which means that all of the bacteria in the colony are genetically related. This allows scientists to identify the bacteria by its unique characteristics, such as its color and size. Secondly, it is assumed that the bacteria are capable of reproducing, since it is only possible for the colony to form if the bacteria are able to divide and multiply. Lastly, it is assumed that the bacteria are not contaminated with any other microorganisms, since the bacteria need to be isolated in order to form a colony.
These assumptions allow scientists to accurately identify the bacteria and gain a better understanding of its characteristics. This knowledge can then be used to further research and study the bacteria, as well as develop treatments or vaccines if necessary. Therefore, these assumptions are essential in understanding the biology of the bacteria and its potential implications on human health.

How do you get the macromolecules in your body?
Answer:
explanation
Explanation:
Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. These macromolecules (polymers) are built from different combinations of smaller organic molecules (monomers).
Why do cells need to have a high surface area relative to their total volume?
Smaller single-celled creatures have a high surface area to volume ratio, which enables them to rely on waste removal and oxygen diffusion to thrive. This method can be more successful if the objects have a larger surface area to volume ratio.
What is high surface area?Material with a large surface area acts as an active species' support or catalyst. Precipitation, sol-gel, or flame methods are frequently used to synthesize them. A flexible option is "exotemplating," which uses porous carbon matrices as a hard template, for example.
What is carbon with a high surface area?NaOH at a temperature of 7000C produces activated carbon with a large surface area of around 2400 m2/g . But only irregular materials and irregular intercalation processes may be activated by NaOH [21]. Activated carbon used for this investigation, however, must have a high porosity level.

Write a claim evidence and reasoning on Do trees change the composition of the atmosphere around us?
Answer:
Evidence: Trees absorb carbon dioxide from the atmosphere during the process of photosynthesis, and release oxygen as a byproduct. In this way, trees play a vital role in the global carbon cycle, and can help to mitigate the negative impacts of human activities that contribute to the increase of atmospheric carbon dioxide, such as the burning of fossil fuels.
Reasoning: The evidence provided demonstrates that trees have a direct effect on the composition of the atmosphere through their role in the carbon cycle. By absorbing carbon dioxide and releasing oxygen, trees can help to balance the levels of these gases in the atmosphere, and contribute to the overall health of the planet. The fact that trees have this ability suggests that they have the power to change the composition of the atmosphere around us.

According to the theory of evolution by natural selection as presented by Darwin, organisms breed more young than they can withstand in their surroundings.
Charles Darwin's theory of evolution is known as natural selection. Animals with heritable traits that favor survival and reproduction will often generate more offspring than their contemporaries given the shortage of resources in nature, increasing the population frequency of such traits across successive generations. Those with more physical capacity to endure, develop into adults, and reproduce.
Darwin started to question if South American species had made it to the Galapagos and had since transformed as a result of climatic adaptation. This notion—that species could alter over time—ultimately inspired Darwin to develop his theory of evolution through natural selection.

Known for their distinctive black, orange, and white coat patches, the calico cat is an example of a genetic process known as "lionization." Because calico cats have a genetic condition called spotting. Mottled animals have white skin or patches of white fur. This is controlled by genes that affect the ability of skin cells to produce the pigments responsible for color.

The cell cycle is an organized series of processes that take place in a cell before cell division.
What is Cell cycle?The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S).
Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2. A cell "decides" whether to enter the cell cycle and divide based on the stimulatory and inhibitory signals it receives.
Growth factors, growth factor receptors, signal transducers, and nuclear regulatory proteins are the four groups that can be used to categorize the proteins that are involved in promoting cell division.

Screens out harmful radiation
Answer:
Explanation:
With the arrival of warm summer weather, states have started to relax their COVID-19 stay-at-home orders. Excited to spend time with family and friends, people are now planning vacations, with one destination remaining a popular choice for many: the beach. However, extra time spent soaking up the sun increases our exposure to harmful ultraviolet (UV) radiation and raises our risk for developing skin cancer.
July is UV Safety Month. We know that one of the best ways to practice UV safety is to wear sunscreen every day. To help you choose and correctly use the best product for your needs, review the nine facts about sunscreen listed below.
Fact #1: Broad Spectrum Sunscreens are Best
UV radiation from the sun includes two types of harmful rays:
Ultraviolet A (UVA) Rays: Most common; cause premature aging of the skin (e.g., wrinkles)
Ultraviolet B (UVB) Rays: Most dangerous; cause sunburns
Overexposure to both types of rays can cause skin cancer. Sunscreens labeled as “broad spectrum” help protect against the effects of both UVA and UVB rays.
Fact #2: Aim for a Sunscreen with at Least 30 SPF
A sunscreen’s sun protection factor (SPF) indicates how much protection the product offers against UV radiation. Sunscreens with an SPF of at least 30 block 97 percent of the sun’s rays.
Fact #3: No Sunscreen is Waterproof or Sweat Proof
Manufacturers can no longer advertise sunscreens as waterproof or sweat proof. Instead, products are now labeled:
Water Resistant: Effective for up to 40 minutes in water
Very Water Resistant: Effective for up to 80 minutes in water
The AAD recommends reapplying sunscreen every two hours, after getting out of the water, or after sweating.
Fact #4: Children Under Six (6) Months Typically Should Not Wear Sunscreen
Infant skin is more sensitive than adult skin. To protect infants younger than six months, the AAD recommends keeping them in the shade as much as possible; dressing them in protective clothing, such as long-sleeved shirts, pants, and a wide-brimmed hat; and making sure they stay hydrated. If you are still concerned about sun exposure, ask your pediatrician if he/she recommends sunscreen.
Fact #5: Sunscreen is Only One Tool in Your UV Safety Toolbox
There are many ways to reduce your exposure to UV radiation. Experts recommend combining sunscreen use with wearing protective clothing, staying in the shade when possible, and avoiding outdoor activities when the sun is most intense.
Fact #6: Use “Teaspoon and Shot Glass Rule” to Determine How Much Sunscreen to Apply
Many people do not apply enough screen. The “Teaspoon and Shot Glass Rule” recommends using one teaspoon of sunscreen to cover the face and neck, and enough sunscreen to fill a shot glass — approximately one ounce — to cover all other exposed areas on the body.
Fact #7: Sunscreen Expires
According to the AAD, the FDA requires all sunscreens to retain their original strength for at least three years. Many sunscreens include an expiration date printed on the label. Visible changes in color or consistency can also indicate that it is time to dispose of the product.
Fact #8: Spray-On Sunscreens Are Convenient, But Not Always Effective
The AAD explains that current FDA regulations on testing and standardization do not apply to spray-on sunscreens. Individuals who want to use spray-on sunscreen should make sure to use an adequate amount, rubbing it in to thoroughly cover all areas of exposed skin.
Fact #9: Sunscreen is Safe to Use
Some recent news stories have called into question the safety of the ingredients used in sunscreens, but sunscreen remains completely safe to use and is recommended by all health care professionals. Read more about this in our blog post titled “Is Sunscreen Safe?”

What is the relationship of III-1 to 111-2?
The relation of III-1 to 111-2 is that they are the married couple having some common ancestor and having 3 children where 1 girl and 1 boy suffer from some sex linked recessive disease.
What is Sex linked recessive disease?X-linked recessive inheritance also known as Sex linked recessive disease which is defined as the mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to always be expressed in males and in females that are homozygous for the gene mutation. Females with one copy of the mutated gene are carriers.
Examples of X-linked recessive disease are red-green color blindness and hemophilia A where there is red-green color blindness. Red-green color blindness simply means that a person cannot differentiate between red and green colors (usually blue-green).

Many mutations are in reality "random," according to tests, and did not happen because the organism was put in a setting where the mutation would be advantageous.
Esther and Joshua Lederberg found that many of these mutations for antibiotic resistance were already present in the population in 1952, even before the population had been exposed to the antibiotic.
