natural chemicals in the brain that cause feelings of relaxation and happiness are called​

Answers

Answer 1
This is either serotonin or dopamine. Dopamine is the reward chemical, and tends to be more euphoric than relaxed, so I think it’s serotonin, which is typically called the “happiness hormone”

Order the following words for Transcription
1 pre-mRNA
2.Gene
3 DNA
4mRNA

Answers

Answer:

2. Gene

3. DNA

1. Pre-mRNA

4. mRNA

Explanation:

Transcription is the first step of gene expression in which a DNA molecule serves as template for the synthesis of mRNA. In the process of transcription, a Gene present on the DNA molecule is transcribed by RNA polymerase using complementary base pairing rule.

After the gene is transcribed, a pre-mRNA is formed. This mRNA is so called because it is immature. The pre-mRNA undergoes processing such as polyadenylation, splicing etc. to become a mRNA.

Hence, based on this, the order is:

Gene → DNA → pre-mRNA → mRNA

Layers of shells from once-living organisms and sediment are cemented together and turn to rock, storing the carbon in stone called limestone. This process moves carbon atoms from the biosphere to the geosphere (lithosphere).

Answers

Answer:

Sedimentation.

Explanation:

The process that is responsible for the movement of carbon atoms from the biosphere to the geosphere is called sedimentation. Carbon enters the geosphere or lithosphere through the biosphere when dead organic matter becomes incorporated into the soil that turns the shells of calcium carbonate to become limestone through the process which is called sedimentation. This sedimentation process is very necessary for the formation of different types of minerals such as limestone, fossil fuels etc.

Explain how carbon cycles through the ecosystem in which you live.

PLEAASE HELP :((

Answers

Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

Which of the following is a correct statement about the relationship between natural selection and evolution?
(3 points)
A. Natural selection results from evolution.
B. Natural selection includes evolution as a part of it.
C. Natural selection is one mechanism of evolution.
D. Natural selection and evolution are the same thing.

Answers

The answer is I believe is c

The statement 'natural selection is one mechanism of evolution' is CORRECT (Option C).

Evolution refers to the modification of inherited phenotypic traits in successive generations as a consequence of the adaptation to specific environmental conditions.

Natural selection is considered the main force driving evolution.

This mechanism (natural selection) increases the frequency of adaptive genes and/or alleles across generations by differential survival and reproduction of organisms better adapted to the environments in which they live.

In conclusion, the statement 'natural selection is one mechanism of evolution' is CORRECT (Option C).

Why does the moon turn red during a total lunar eclipse?

Answers

Answer:

In the case of a lunar eclipse, red light can pass through the Earth's atmosphere and is refracted - or bent - toward the Moon, while blue light is filtered out. This leaves the moon with a pale reddish hue during an eclipse.

mark me brainliestt :))

Answer:

Our planet is much larger than the Sun, but the light of our homestars bends around the edge of the Earth. This light reflects off the moon. But not before it passed through our atmosphere. It filters out shorter wavelength blue light and leaves red and orange intact to soak the surface of the moon

.Why are shadows shorter around noon?
Make sure you give a full, detailed answer, not just one sentence.

Answers

At noon the sun is directly overhead the sun rays fall vertically on the body so the shadow is very short.

So the rays fall vertically on the body. in mornings and evenings the rays fall at inclined position. So shadows are long at mornings or evenings.

Shadows are shortest at noon because the sun is directly overhead. So the rays fall vertically on the body. In the morning and in the evening, the rays fall at inclined position. So shadows are longer during morning and evening.

4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.

Answers

Answer:

The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

Explanation:

shivering burns fat to help keep one warm

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
