How are these atoms used to make new molecules and what types of molecules are made? Where does the energy come from to produce these new molecules?

Answers

Answer:

Atoms used energy to make new molecules.

Explanation:

Atoms used energy to make new molecules through making bonds with one another because bonds allow atoms to attached tightly with each other. The energy come from the external environment in order to produce new molecules. So we can conclude that energy is the main ingredient needed for making new molecules and this energy is gained from the environment.

Jason, i don't have much time because I'm very tired and i have to go to bed but this a good example of homeostasis.

Imagine that the cell is exposed to some kind of stressor such as extremes of temperature, exposure to toxins, or mechanical damage. The chain reactions will be

Disruption or the formation of cell membrane blebsAlteration of protein synthesis and accumulation of altered proteins in the ERAlteration of the chromatin of the chromosomes inside the nucleus and DNA damageAlteration of the permeability of organelles such as mitochondria with consequent alterations in metabolismDecrease in ATP levels and increase in cytoplasmic calcium level

The combination of all this can lead the cell to death but it can respond in various ways:

the cell can decrease protein synthesis and induce the transcription of specific stress-sensitive chromosomal genes that correct altered proteinsIt can respond to DNA damage by stopping replication and trying to repair it If it cannot survive it can commit suifcide so as not to harm other cells

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.

what do you know about energy and cells?

Answers

Answer:

Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.


In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.

Answers

Explanation:

A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.

each square would have 25% each because 100%÷4=25.

Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.

Blue is recessive.

The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Performing a cross

Given that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.

Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Antibiotics have become diluted and weak because of a limited supply.

Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.

A researcher prepares a suspension of mitochondria from tissue and monitors the respiration of the mitochondria by the rate of oxygen (O2) consumption in the presence of pyruvate. When the researcher adds an inhibitor of isocitrate dehydrogenase to the suspension, oxygen consumption (respiration) stops.

Answers

Answer and explanation:

The mitochondria are the organelle responsible for respiration, which leads to the production of ATP - the most important molecule in energy transfer.

For respiration to happen, there are several processes involving chemical reactions that take place in the mitochondria. These mechanisms are: oxidative decarboxylation, Krebs cycle, and oxidative phosphorylation. Glycolysis is also important for these processes to occur, but this particular case happens outside of the mitochondria.

Pyruvate is an important precursor of the Krebs cycle, also called 'the citric acid cycle'. The researcher observes the functioning of the mitochondria in presence of pyruvate, but then adds an inhibitor of isocitrate dehydrogenase. This inhibitor cancels out the action of the isocitrate dehydrogenase, which is a key enzyme in the Krebs cycle. By inhibiting this enzyme, the cycle cannot continue, and respiration stops.

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.
