Which factors add to the greenhouse effect and are caused by human activities? Select two options. (This question requires Two answers)
A.a decrease in the amount of dust in the atmosphere
B.a decrease in the amount of water on Earth’s surface
C.an increase in gases in the atmosphere that absorb heat
D.an increase in surfaces that radiate energy into the atmosphere
E.an increase in the amount of solar radiation that reflects into space
Answer:
There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to.Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
Explanation:
EXAMPLES: Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. ... Deforestation: Forests hold a major green area on the planet Earth. ... Increase in Population: Over the last few decades, there have been huge increase in the population.What precautions should be made to be sure that there is little chance of negative consequences from an oil spill?
Answer:
hi, here's the answer of your question
Tighten bolts on your engine to prevent oil leaks.
Replace cracked or worn hydraulic lines and fittings before they fail.
Outfit your engine with an oil tray or drip pan.

Which of the following are functions of protein molecules in an animal?
1. Protein molecules help cells carry out many of their functions, and they are part of body structures such as hair and nails.
2. Protein molecules help cells carry out many of their functions, but they are not part of body structures such as hair and nails.
3. Protein molecules do not help cells carry out many of their functions, and they are not part of body structures such as hair and nails.
4. Protein molecules are part of body structures such as hair and nails, but they do not help cells carry out many of their functions.
Answer:
1. Protein molecules help cells carry out many of their functions, and they are part of body structures such as hair and nails.
Explanation:
Proteins are one of the four major biomolecules in living systems. Proteins play a major role in the physiological, structural and metabolical processes in living organisms. They help cells carry out many functions when they acts as enzymes and hormones. Enzymes and hormones are proteinous chemical substances that catalyzes and speedens up physiological reactions respectively.
In addition, proteins are major structural components in animals. For example, keratin is a protein that makes up the hair and nails of animals. They provide structural support in parts of the body they are found.

Evidence: Mrs. Macy is very dissatisfied with her tomato plants this year. If she doesn’t turn it around, it will be challenging to put food on the table. There has been a low yield of fruit and the plants are short and stunted. Some of the leaves have a mosaic pattern of dark spots on their leaves.
Conclusions:
Suspected disease: ________________________________________________________

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
Why did natural selection not cause mammoths to evolve new adaptations in response to environmental changes instead of becoming extinct?
A. There were too many offspring in the population.
B. There were too many different traits in the population.
C. There was not enough competition in the population.
D. There was not enough variation in the population.
Answer:
Explanation:

Explanation:
It may be harmful when people compete to see who can hold their
breath the longest under water. Without oxygen, brain cells
Answer:
tend to not get enough oxygen which may lead to severe brain damage and our brains can get Celebral Hypoxia which includes symptoms such as confusion and loss of coordination
Explanation:
When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia.
When one holds his/her breath under water the amount of oxygen flowing into the brain cells is cut off and if the oxygen supply is not restored within 5 minutes, the brain cells will start dying off which will result to severe brain damage and eventual death .
Hence we can conclude that When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia .

Why is the point of attachment of the frog's tongue considered to be advantageous?
Answer:
Frog's tongues are attached to the front of their mouths rather than at the back like humans.
Explanation:
This is an advantage because most frogs eat flies and insects and the like. Because they can flick their tongue a long way out they are able to catch food more effectively. This is an example of an adaptation.
Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

FIRST PERSON TO ANSWER GETS BRANLYSEST After Hunter drank a glass of milk, sugar levels in his blood increased. This stimulated the hormone insulin to be released. Insulin helped the sugar move from his blood into cells, so his blood sugar levels decreased. Which statement explains what happened next? Positive feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to produce more insulin. Positive feedback caused his pancreas to produce more insulin.
Answer:
The correct answer B
When the body gets the glucose, the glucose in the blood increase then the hormone insulin is released so that the glucose from the blood can be transferred from blood into the cells of the body.
The release of hormone insulin is a positive feedback.
Once the glucose is transferred into the cells of the body then the negative feedback starts acting that stops the secretion of insulin from the pancreas.
What will happen next is that negative feedback would cause his pancreas to stop secreting insulin.
The maintenance of relatively constant internal body processes depends largely on negative feedback.
Negative feedback mechanisms ensure that setpoints are returned.
Hence, whatever causes setpoints to be breached is reversed or removed totally.
In this case, the continuous secretion of insulin will further lower the blood sugar level and causes the setpoint to be breached further. Thus, the actuator (insulin) has to be removed.
More on negative feedback can be found here: https://brainly.com/question/15379119?referrer=searchResults

This was simulation. What are some variables that this peppered moths simulation does not address?
Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.
