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.
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.

Explain how carbon cycles through the ecosystem in which you live.
PLEAASE HELP :((
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.
Explanation:
During cell division, where are
chromosomes duplicated?
A. membrane
B. mitochondria
C. nucleus
D. vacuoles
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).
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.
how do you solve for percentage in a punnett square?
Answer:
Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.

Given a parent genotype of Bb, what are the possible gametes that they can produce?
Assuming both parents have genotype Bb, this would lead to the Punnett square (in this case a monohybrid cross) as shown in the image below. We have four outcomes, three of which are unique. Those offspring genotypes are: BB, Bb, and bb.
An offspring with B or b on its own is not possible because both parents contribute genes.
.Why are shadows shorter around noon?
Make sure you give a full, detailed answer, not just one sentence.
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.

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

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.
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).
