5. Why are metamorphic rocks formed by contact metamorphism usually not as dense as those
formed by regional metamorphism?
Answer:
The rock was altered by high temperature with extreme pressure
Explanation:
Fossils would be destroyed
Metamorphic rocks formed by contact metamorphism are usually not as
dense as those formed by regional metamorphism because of their mode of
formation which involves a higher temperature without little or no pressure.
Contact metamorphism involves rock formation as a result of contact with
hot magma. The regional metamorphism involves the formation of rocks
deep in the soil through extreme temperature and pressure over a wider
area.
This is the major reason why the metamorphic rocks from contact
metamorphism are denser than the regional metamorphism.

Explanation:
Which organ system supplies the body with oxygen? *
Answer: It would be the resperatory system. Your lungs are the main part of that.
Explanation:
Answer:
The respiratory system
Explanation:
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs.
A growling stomach and the stimulation of hunger represent the
A
integumentary system and the endocrine system working together.
B
excretory system and the respiratory system working together.
с
digestive system and the nervous system working together.
D
muscular system and the skeletal system working together.
A growling stomach and the stimulation of hunger represent the digestive system and the nervous system working together. The correct option is c.
What is hunger?Hunger is primarily a biologically induced desire for food, which is required for survival.
Hunger can thus be regarded as a quantifiable biological trait of humans that predicts the willingness to eat as well as the amount of food consumed.
During fasting, the stomach secretes the "hunger hormone" ghrelin to promote food intake.
Ghrelin stimulates appetite by activating its receptor GHSR1a in the brain's hunger sensing neurons, and thus represents a promising avenue for the development of anti-obesity treatments.
A growling stomach and the stimulation of hunger represent the digestive and nervous systems collaborating.
Thus, the correct option is C.

What is ONE major difference in the problems associated with obtaining measurements on the sizes or densities of animal populations versus plant populations?
I think one major difference with that is that animals can move around, go distances in search for food or mate, and thus make the animal densities per geography vary greatly. Birds migrate regularly, so their population densities tend to vary with seasons. Their mobility also depends on the availability of food, so animals go away if there are no food in the area.
Plants on the other hand don't move around faster (they can migrate by reproduction: it's their seeds moving around). Thus their densities tend to be more constant per season/life cycle.
Answer #14 and will mark brainliest

The populations of different artic animals would start to decrease because of the lack of land and food.

What is the short definition of a plant cell?
Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals. Nucleus part main job is to direct a plant cell's activities by sending instructions to different parts of the cell.
Therefore, The part whose main job is to direct a plant cell's activities by sending instructions to different parts of the cell is the nucleus. It directs the cell's activities in the plant and animal cells.

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.
identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?
Answer:
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
Radiation does not have effect on strength of the mice
Explanation:
In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.
The control group is the group that does not receive treatment which is used to compare the effect of the treatment.
The control variable is another variable that must be held constant when performing the experiment.
Here the
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

B. Using negative feedback to increase its internal temperature when it falls below its normal range
Explanation:
The question asked about INTERNAL temp and how its stbalized, we know that MOST to ALL of negative feedback is getting the organism to return to its original state, high body temp was its original state, therfore,Using negative feedback to increase its internal temperature when it falls below its normal range, is the correct answer.
Meiosis I involves separation of homologous chromosomes but meiosis II involves separation of chromtids.
Answer:
Meiosis I: in meiosis I there is pair of chromosomes called homologous chromosomes which are to be seperated so one of that two chromosomes right pole of the cell and the second one goes to the left pole so each pole gets a chromosome with two sister chromatids.
Meiosis II: While in meiosis II homologous pair is not formed and single array of chromosomes are arranged to form metaphase plate as formed in Mitosis so, when the spindle fibres contracts each sister chromatids went to their respective poles.

Define permafrost in you own words!
Answer:
Permafrost is ground that continuously remains below 0°C for two or more years, located on land or under the ocean. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface.
Explanation:
Answer: pick one
try this,
Permafrost is a permanently frozen layer on or under Earth's surface. It consists of soil, gravel, and sand, usually bound together by ice. ... Permafrost covers approximately 22.8 million square kilometers (about 8.8 million square miles) in Earth's Northern Hemisphere. Frozen ground is not always the same as permafrost.
or try this,
Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".
