Please help me I do not know how

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.

Explanation: did the test and got it right

Answer:

Make an observation.

Ask a question.

Form a hypothesis, or testable explanation.

Make a prediction based on the hypothesis.

Test the prediction.

Iterate: use the results to make new hypotheses or predictions.

Explanation:

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.

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.

Answer:

Jupiter. Mercury. Saturn

Explanation:

Your option(the third) is correct since all the cells in an organism have the same genetic material

the first one is false because all cells contain the same dna

the second one is false because the dna stays the same

the fourth one is false because sea animals have different dna

Answer:Some of these include: disease, predator/prey relationships, habitat destruction and degradation, food availability, hunting pressure, and weather conditions. Deer populations are not static; they continuously change in response to many factors.

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.

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.

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

Answer:

To maintain homeostasis, the paramecium must pump out large amounts of water using its contractile vacuole. If the paramecium is then placed in a hypertonic environment, which of the following will occur? A Water will diffuse into the paramecium.

Explanation:

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.

Answer:

all nations should face the same percentage reductions in emissions

Explanation:

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.

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.

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.

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.

Answer:B

Explanation:

Answer:

It is denser when frozen than when liquid.

Explanation:

Ice is actually less dense than water. The lattice arrangement of ice allows water molecules to be more spread out than in a liquid, making ice less dense than water.

Hope that helps.

Answer: Flashlight

Explanation: The sparkles of a mineral is also known as it's luster. For example, a diamond when in the sun or under a source of light will shine due to the reflection of the sun. A flashlight is also a tool that can be used to observe the sparkles of a mineral, or in other words it's luster.
