Answer:
particulate matter
Explanation:
The most likely pollutant that is capable of causing a decrease in a forest's biodiversity, as well as decreased growth and reproductive health of individual plants within the forest, would be particulate matters.
Particulate matters in the atmosphere generally get deposited on the organs of plants such as leaves, stems, and flowers. When this happens, they block the various openings of the organs such as stomata, lenticels, and hydathodes.
The blockage of these openings results in several physiological processes such as photosynthesis and gaseous exchange being negatively affected leading to decreased growth, reproductive health, or sometimes, outright death of plants.
The death of many individual plants in a forest eventually leads to a decrease in the diversity of the forest.

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.

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.

Data Collection: Pinky's science fair project in junior high focused on an observation that the
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).

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.
You are part of a group of researchers working on determining the genetic basis for early onset Osteoporosis. Using data from subjects in Iceland, you are able to identify where the mutation is located. The target gene in unaffected people produces the amino acid sequence Pro-Met-Glu-Arg-Asp. In individuals with the mutation, the protein produced has a sequence of Pro-Met- then stops. What type of mutation is this?
Answer:
This question lacks options; the options are:
A) Deletion mutation
B) Missense mutation
C) Inversion mutation
D) Nonsense mutation
The answer is D) Nonsense mutation
Explanation:
A mutation in genetics refers to the change in the nucleotide sequence of a gene or DNA segment. The occurrence of mutation in a gene leads to different effects, which is the basis of the different types of mutation. The type of mutation described in this question is called a NONSENSE MUTATION, which is a type of base substitution mutation.
Nonsense mutation is the mutation in which one nucleotide base in the sequence gets replaced by a STOP CODON (UAA, UAG, UGA), leading to the truncation of the amino acid sequence and hence, the production of a non-functional protein.
This is the case in this mutated gene sequence whose normal sequence codes for: Pro-Met-Glu-Arg-Asp. The mutation causes the codon specifying Glutamine to be replaced by either of the STOP codons, thereby, stopping the translation process. The stop to the translation process causes the amino acid sequence to be truncated and a non-functional amino acid sequence is formed: Pro-Met-

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.

Answer:
A major transcription factor is inactivated or an oncogene is overexpressed
Explanation:
A microarray is a technique widely used in molecular biology for the detection of the expression of target genes. A microarray is composed of microscopic spots that contain DNA probes which hybridize with the target acid nucleic (generally an mRNA). The hybridization of probe-target produces fluorescence or chemiluminescence, thereby it is possible to detect gene expression in the sample. The inactivation of major transcription factors (e.g., p53) or overexpression of oncogenes (e.g., c-Myc) are well-known to produce aberrant gene expression patterns as observed in this case.

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

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.

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.

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.
