Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
Why might a company decide against using hydroelectric Energy as an alternative energy source
A. Gathering it requires pulling from unclean sources
B. Gathering it creates noise pollution for surrounding areas
C. Gathering it releases carbon dioxide gases into the air
D. Gathering it can have a negative affect on natural habitats
The company's decision against using hydroelectric Energy as an alternative energy source might be Gathering it can have a negative affect on natural habitats.
Why is hydroelectric power not a good energy source?Hydropower can also cause environmental and social problems. Waterholes drastically change the landscape and rivers they are built on. Dams and reservoirs can decrease river flows, raise the water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.
Thus, the correct option is "D".

use seeds to reproduce
use spores to reproduce
have vascular tissue
have cones as reproductive structures
Answer:
Have cones as reproductive structures.
Have vascular tissue.
Explanation:
The gymnosperms have vascular tissue and have cones as reproductive structures.
What are gymnosperms?The gymnosperms are woody like plants having a cone shaped structure, bear no flowers, no fruits but bear seeds; The seeds are with out coat and they are not covered by the fruit wall.
Gymnosperms produce seeds which are not enclosed in an ovary, while in Angiosperms the reproductive organs are the flower, they may involve in double fertilization resulting in a diploid zygote, and a triploid endosperm.
Gymnosperms produce seeds and fruits from their flowers, the flowers in gymnosperms helped in the propagation of the plants, it attract pollinators and attracted seed to dispersers, gymnosperms became dominant among plants.
The modification of the gymnosperm includes Modified leaves, Sunken stomata, Pointed and thick cuticle leaves, Less transpiration rate.

Aside from solar energy, what else could provide electrons?
Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature.
Small charged particles called electrons, which normally flow via a wire, provide electrical energy. An illustration of electrical energy in nature is lightning.
What are the different sources of electron?The majority of free electrons are created with minimal kinetic energy and just disperse through the atmosphere, participating in the random thermal motion of every atom.
With enough kinetic energy, some free electrons are created that can lead to further ionization and excitation.
The source of electrons is a filament, or cathode. Usually, it is a tungsten wire in the form of a hairpin.
The surrounding cathode cap is given an accelerating voltage (determined quantity of negative high voltage). The filament is then exposed to a tiny emission current to liberate electrons.
Therefore, aside from solar energy, electron are produce.

Direct effects, as the name suggests, while not manipulated or communicated by a third party, deal with the direct influence of one entity on another. Indirect effects can be described as the influence, mediated or passed on by a third, of one organism or species on another.
Where does mRNA come from?
Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus

About the Heart and Circulatory System
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.
What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.
If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Essential amino acids are available to the body through diet.
What are amino acids?Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.
Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.
There are twenty different amino acids present. Amino acids are classified into four main groups:
Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acidsAmino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.
Amino acids are joined together in large number and form polypetides through peptide bond formation.
Based on the nutritional requirements amino acids are classified into two types:
Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.

Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.
