When temperature drops, what muscle is most dominant in pulling the testes closer to the body
Answer:
cremaster muscle
Explanation:
The cremaster muscle covers the testes and the spermatic cord.
The muscle raises and lowers the testes in order to regulate the temperature of the scrotum
When temperature drops, the cremaster muscle pulls the testes closer to the body.
• The muscle found within the body of male and covers the testis is the cremaster muscle.
• The muscle moves the testis, encouraging motile and healthy sperm.
• The cremaster muscle raises and lowers the testis in order to control its temperature. When a man moves into an environment with a colder temperature, the muscle makes the testis to move closer to the body.
• The muscle also functions at the time of flight or fight scenarios, when the man runs to enters a fight, the muscle pulls the testis closer to the body and safeguard it.
Thus, the cremaster muscle pulls the testis closer to the body when temperature drops.

In science, why is it important to explain why the evidence supports your claim?
Answer:
Evidence helps convince the audience to accept your answer. If your don't have evidence it's less likely for anyone to believe your claim
Explanation:
If you are a scientist and do not support your claim with evidence, the claim is not valid.
In different sciences it is necessary to carry out experiments, that is, a procedure that serves to verify or discard any idea or possible explanation of a phenomenon.
When a scientist develops a theory to explain a phenomenon it is necessary to put it into practice because the ideas or hypotheses cannot be considered as true knowledge.
Experiments are a fundamental part of knowledge since they give credibility to studies and allow the creation of new knowledge about different disciplines. Even when the experiments don't go the way they want, they leave a learning curve for scientists.

When the potential energy is lowest, what is true of the kinetic energy?
Answer:
The kinetic energy is larger than or equal to the kinetic energy
Explanation:
The total mechanical energy in a body is made of the sum of the potential and kinetic energy of the body as such, given that the total mechanical energy of the body remains constant, as the potential energy reduces, the kinetic energy of the body increases.
For example, an object at an elevated point as a high potential energy and 0 kinetic energy as the object falls, the potential energy is converted to kinetic energy and the and the speed of the object increases. The kinetic energy is highest just before the object touches the ground, at which point the potential energy is lowest
Therefore, when the potential energy is lowest, the kinetic energy is either equal to (for objects at rest state) or larger than (for momentary dynamic systems) than the potential energy.

Which statement explains the difference between a nerve that is connected to the skin and a nerve that is connected to a muscle? The nerve that is connected to skin is a motor neuron; the nerve that is connected to a muscle is a sensory neuron. The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain. The nerve that is connected to skin is part of the central nervous system; the nerve that is connected to a muscle is part of the peripheral nervous system. The nerve that is connected to skin helps the body maintain homeostasis; the nerve that is connected to a muscle supports the body so it can stand upright and move from place to place.
Answer: Hi! The answer you're looking for is:
"The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain."
When you receive, for example, a touch on your arm, the nerves connected to your skin transfer the information of this touch to your brain - in other words, it tells you how it felt. This touch would obviously be external, or outside of your body. Nerves connected to your muscles transfer information like how your muscles feel after hard exercise, or directions from your brain on how to move a muscle - I'm using my arm muscles and my finger muscles right now to type this answer for you! This would be internal.

What is the monomer (single unit) that makes up the polysaccharides?
Answer:
monosaccharides
Explanation:
The monomers of polysaccharides are the monosaccharides, otherwise known as the simple sugars. The monosaccharides are linked together by bonds known as glycosidic bonds.
For example; starch, cellulose, and glycogen are polysaccharides whose monomer units are glucose - a monosaccharide. The glycosidic bonds in starch and glycogen are alpha while those in cellulose are beta glycosidic bonds. The latter is formed when the hydroxyl group on the first carbon of the sugar is above the glucose ring while the former is formed when the hydroxyl group is below the ring.
Polysaccharides are complex biomacromolecules that are made up chains of monosaccharides. The bonds that form these chains are glycosidic bonds. Commonly found monomer units in polysaccharides are glucose, fructose, mannose and galactose which are simple sugars.
Alteration of histones by addition of methyl and acetyl groups to particular amino acids Alteration of histones by addition of methyl and acetyl groups to particular amino acids results in the remodeling of chromatin that can activate or inhibit gene expression. changes B-DNA to Z-DNA. helps preserve telomeres during DNA replication. alters the denaturation and renaturation of DNA. creates G bands seen after Giemsa staining of chromosomes.
Answer:
results in the remodeling of chromatin that can activate or inhibit gene expression
Explanation:
In a similar mode to the DNA methylation, different types of histone modifications (including, among others, methylation, acetylation, ribosilation, phosphorylation, etc) can regulate gene expression patterns. Both DNA and histone modifications are epigenetic hallmarks capable of modulating chromatin organization and consequently also the accessibility to transcription factors, thereby having effects on gene expression. In this regard, it is important to note that regulatory non-coding RNA molecules can also epigenetically regulate gene expression.

Answer:
Rate = 2 cm/year
Explanation:
It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.
We know that, 1 m = 100 cm
200 m = 200 × 100 cm
= 20000 cm
Its rate is given by :
[tex]R=\dfrac{20000}{10,000}\\\\R=2\ cm/year[/tex]
So, the plate is moving at a rate of 2 cm/year.
______ are chemical messengers secreted by glands. Exocrine glands, such as sweat glands, secrete fluids through ducts. _______ glands secrete hormones directly into the bloodstream. The _______ gland plays an important role in puberty and growth. Epinephrine, triggering the "fight or flight" response, is produced by the _______ glands, which sit on top of the kidneys. Most glands that secrete hormones operate using feedback mechanisms. When hormone concentrations are high, the gland will produce ________ of the hormone. Many cells produce chemicals called _______, hormone-like substances that impact inflammation and reproduction. The gland that helps regulate growth, body temperature, and the level of calcium in the blood is called the _______. Describe the function and compare steroidal and nonsteroidal hormones. How does each type of hormone interact with the cell? What other molecules are required for or involved in their function?
Answer:
Hormones
endocrine
pituitary
adrenal
less
prostaglandins
thyroid
Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.

crickets outside her window chirped less frequently when the temperature was colder.
Fun Fact: There are free "cricket chirp calculators" online you can explore, which
didn't exist freely online when Pinky was in junior high.
Consider if data was collected consisting of the average number of cricket chirps
at different temperatures in her backyard. in the collection of data list at least 3 important constants?
Answer:
The three important constants are: The person who will collect the data (Pinky), the environment in which the data will be collected (Pinky's backyard) and the element who will provide the data (the crickets).
Explanation:
Constants are very important elements in carrying out controlled experiments. This is because they allow all measurements and data collections to be carried out in constant systems that do not change and that will provide unity and control to the experiment.
In short, the constants are the elements of the experiment that will not be modified while the experiment takes place. These elements are: the person who is conducting the experiment and who will collect the data (Pinky), the environment in which the data will be collected (Pinky's yard) and the element who will provide the data (the crickets).
