Which of the following factors most likely triggers arousal from hibernation?
A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate
Answer:
A) the sun rising in the morning
Explanation:
In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.
According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.
which of the following best describes how the potential is affected by the structural change in the gene?
Answer:
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

Answer: Term Meaning
Monomer A molecule that is a building block for larger molecules (polymers). For example, an amino acid acts as the building blocks for proteins.
Polymer A large molecule made of repeating subunits (monomers). For example, a carbohydrate is a polymer that is made of repeating monosaccharides.
Explanation:
The bacteria we are growing contain both chromosomal DNA and plasmid DNA. Both are circular, but they are different. In 3-5 sentences, discuss at least 3 differences between the chromosomal DNA and plasmid DNA found in our bacterial cells.
Answer:
Please find the explanation of the differences between chromosomal DNA and plasmid DNA below
Explanation:
As stated in this question, a bacteria cell contains both chromosomal or genomic DNA and an extra chromosomal DNA called PLASMID. They are both circular in shape but are different from one another in the following ways:
- Chromosomal DNA is larger in appearance than the plasmid DNA, hence, they differ in terms of size.
- Chromosomal DNA encodes all the information in the genome of the bacterial cell necessary for their growth and development while plasmid DNA encodes few additional beneficial characteristics such as antibiotic resistance, virulence etc.
- Chromosomal DNA is wrapped around histone proteins to form the chromosome structure but plasmid DNA is naked and not wrapped around histone proteins.
Describe how transposable elements create mutations within an organism and how transposable elements facilitate chromosomal rearrangements.
Answer:
Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.
Explanation:
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

Explanation:
Cleo found an arthropod in a grassy field. The arthropod has six pairs of legs, two pairs of antennae, two body sections, and an open circulatory system
Q: Which conclusion is best supported by the information?
A: The arthropod is an arachnid because it has two body sections and an open circulatory system.
B: The arthropod is an arachnid because it has six pairs of legs and two pairs of antennae.
C:The arthropod is a crustacean because it has two body sections and an open circulatory system.
D: The arthropod is a crustacean because it has six pairs of legs and two pairs of antennae.
Answer: C:The arthropod is a crustacean because it has two body sections and an open circulatory system.
Explanation:
Crustacea are the arthropods. which includes the crabs, shrimp, barnacles, and others. These are the insects. These are the invertebrates. They have hard exoskeleton and segmented body forms. They are bilaterally symmetrical animals. They have four to six pairs of appendages which are jointed. Open circulatory system is present due to lack of developed blood vessels circulation.

Are the fatty acid tails saturated or unsaturated?
and What type of lipid is shown in the picture?
Answer:
The fatty acid tails saturated or unsaturated is discussed below in details.
Explanation:
Fatty acids contain a carboxylic acid association and a great hydrocarbon series, which can either be saturated or unsaturated. A saturated fatty acid tail only contains carbon-carbon individual bonds, and an unsaturated fatty acid has at the slightest individual carbon-carbon twice or triples bond.

Which material would get electrons from the source to the load the fastest
Answer:
However, graphene has far fewer electrons than copper, so in graphene the electrical current is carried by only a few electrons moving much faster than the electrons in copper." In semiconductors, a different measure, mobility, is used to quantify how fast electrons move.

What are the 2 types of fatty acids (and explain what each means, and an example)?
Answer:
saturated and unsaturated fatty acids
Explanation:
Saturated fats are a type of fat in which the fatty acid chains have all or predominantly single bonds.Rich sources of dietary saturated fatty acids include butter fat, meat fat, and tropical oils.
An unsaturated fat is a fat or fatty acid in which there is one or more double bond in the fatty acid chain. these include avocados, olive oil, fatty fish and nuts or seeds.
After concluding his research, which statements would Virchow agree with? CHECK ALL THAT APPLY.
Living things come from nonliving things.
Cells can come from nonliving materials.
Frogs can come from mud.
Living things can only come from living things.
Cells come from pre-existing cells.
Answer:
Living things can only come from living things.
Cells come from pre-existing cells.
Explanation:
Rudolf Virchow a german physicist, biologist and many more, In 1855 Vproposed that cells come from pre-existing based on his observations in exact words 'Omnis cellula e cellula', which translates into all cells arise from pre-existing cells.
He also said the living things come from living things and do not arise from nonliving things or matter. His discoveries made possible the cell theory

from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.
