can some one please confirm my answers please

Answer:

The genome is composed of one to several long molecules of DNA, and mutation can occur potentially anywhere on these molecules at any time. The most serious changes take place in the functional units of DNA, the genes. A mutated form of a gene is called a mutant allele.

Explanation:

Answer:

DNA

Explanation:

Mutations occur in the nucleotide sequence of DNA

Energy can neither be created nor destroyed.

Energy can only be changed from one form to another.

I got it right on my test:)

Answer:

Freckles are small brown spots on your skin, often in areas that get sun exposure. In most cases, freckles are harmless. They form as a result of overproduction of melanin, which is responsible for skin and hair color (pigmentation). Overall, freckles come from ultraviolet (UV) radiation stimulation

Explanation:

Answer:

brainliest please

Explanation:

sunlight helps us tan and melanin helps us tan and freckles come from sun exposure and it's basically splotches of melanin

Answer:

False

Explanation:

Soil with least porosity

Thus, the correct answer is 'Clay soil. '

There are other types of soil that can be more crumbly, but this is not the least. Because porous means something is full of tiny holes or openings, you can see that this is the right word to match it with! The least crumbly, or porous would only have a little crack. Good luck, and I hope this helped!

Also....

Clayey soil is the least porous.

Clayey soil is the least porous soil as the spaces between the molecules of the soil is less and water cannot pass through them.

Answer:

Explanation:

Answer:

answer (UNDER)

Explanation:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Answer:

Photosynthesis converts Light and chemical energy in to food-energy molecule sugar and gives off Oxygen

Explanation:

6CO2 + 6H2O → C6H12O6 + 6O2

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.

Carbon dioxide, water and light are all needed for photosynthesis to take place.

Photosynthesis happens in the leaves of a plant.

Answer:

Mark’s dentist gives him a shot before performing a root canal. The dentist says the shot is anesthesia and that Mark won't feel any pain. Mark feels his gums going numb, while the rest of his body is working fine. What has the anesthesia actually done?

The anesthesia has blocked  interneurons from carrying signals to the brain .

Answer:

Due to global warming temperatures at the poles are rising and ice is melting is described below in complete explanation.

Explanation:

Global warming is generating Arctic ice to melt at a very fast pace, ice shows sunlight, while water consumes it. Polar bears might be extinct by 2200 because of melting ice, climate modification, research reflects. Fresh research recommends the Arctic animals are in high danger of being killed into extinction by the finish of the century.

Answer:

Neurons are in charge of receiving stimuli from the environment, transforming them into nervous excitations and transmitting them to the nerve centers, where they organize themselves to give a response.The cycle of depolarization and hyperpolarization of the membrane and return to the resting membrane potential is called the action potential, an all-or-nothing reaction that can occur at rates of up to 1,000 pulses / second. Membrane depolarization that occurs as voltage gate Na + channels open at one point on an axon passively spreads a short distance and triggers the opening of adjacent channels, resulting in the generation of another action potential. In this way the depolarization wave, or nerve impulse, is conducted along the axon.

Explanation:

Neurons are highly specialized cells whose central function consists in the generation and transmission of signals, in order to communicate with the other neurons of the nervous system and with the outside of the organism. They are made up of three parts: the cell body, the dendrites, and the axon. Dendrites are extensions of the cell body with short, tubular branches, through which each neuron receives signals from other neurons. These signals are added or averaged, and in the event that the total intensity of the received stimulus is greater than a certain threshold, the neuron will generate and emit an electrical response signal. This signal will be sent through the axon, which will transmit the information to other neurons through chemical exchange. The axon divides near the end into thin branches that contact other neurons. The point of contact is called the synapse. At the synapse, there is a gap between the two cells called the synaptic cleft. The synapse is produced by the release of chemicals from the presynaptic neuron that excites the postsynaptic, transmitting the informational code. The arrival of an impulse at the end of a nerve fiber causes a chemical compound, a transmitter substance, to be released, which excites the neighboring neuron. The same neuron may have inhibitory and excitatory connections with different neurons, for which it will need to produce different chemicals that act as transmitters. A neuron receives and integrates multiple stimulations through the synapses, those received by the dendrites are added to those received in the soma so that the electrical potential of the cell membrane ends up exceeding the threshold and originates a nerve impulse in the area of ​​the axonal cone. Nerve impulses are electrical signals generated by the spike trigger sites (axon cones) of a neuron as a result of membrane depolarization, which are conducted along the axon to its termination. The transmission of impulses from the endings of a neuron to another neuron, a muscle cell or a gland occurs at the level of the synapses.

Answer:Each cell carries out basic life processes that allow the body to survive. Many human cells are specialized in form and function, as shown in Figure below. Each type of cell in the figure plays a specific role. For example, nerve cells have long projections that help them carry electrical messages to other cells.

have a good day :)

Explanation:

Answer:

C

(3·x^2 - 2·x)·(2·x^2 + 3·x - 1)

= 3·x^2·2·x^2 + 3·x^2·3·x - 3·x^2·1 - 2·x·2·x^2 - 2·x·3·x + 2·x·1

= 6·x^4 + 9·x^3 - 3·x^2 - 4·x^3 - 6·x^2 + 2·x

= 6·x^4 + 5·x^3 - 9·x^2 + 2·x
