Gregory Mendel is the father of genetics

Gregory Mendel is widely considered to be the father of genetics

Option A is correct

How do we explain?

Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.

Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.

Therefore, Option A is correct

The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work

Answers

Answer:

2754.33% increase

Explanation:

The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:

Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%

Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%

Percent change = 2754.33% increase

Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.

The total increase is 2754.33% increase

The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:

Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%

Percent change = [tex]\frac{[(72500 MW - 2540 MW)}{ 2540 MW }* 100%[/tex]

After solving the equation the percent change = 2754.33% increase.

What causes stomach cramps?​

Answers

Answer:

the main causes are, infection,abdominal growth,inflammation,obstruction blockages

Explanation:

“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.

Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).

Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.

Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.

In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.

Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?

Answers

Answer:

because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements

Explanation:

The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.

Noble gases refer to elements in group 18. These elements are renowned for being inert.

As a result of their inertness and because they are all gases, they are sometimes called "inert gases".

This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk. What might be a risk of using this technology to produce milk?

B.
Use of the GAH may increase the amount of hormones in the milk.
C.
Use of the GAH may provide extra milk to feed the poor.
D.
Use of the GAH may allow the farmer to reduce milk prices.

Answers

Answer:

B

Explanation:

A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

What is a genetically altered hormone(GAH)?

The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.

Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
