When the environment acts for or against one extreme characteristic, this is an
example of which category of natural selection?

what are the two main types of chemical bonds?
Answer:
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.
Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.
Hope it helps!!!
Answer:
the two main types of chemical bonds are:
ionic bonds and covalent bonds.
A large industrial company manufactures paper products such as paper towels and napkins using wood pulp. Which of these BEST describes why wood is considered to be a 'renewable' resource?
Answer: The question is incomplete because the options were not given but the options has been gotten from another website.
Here are the options.
a. Wood is routinely recycled to make new wood-based products.
b. Wood products can be manufactured from different tree species.
Eliminate
c. Wood may be replenished by planting new trees to replace those being used.
d. Wood products can be manufactured using various other materials such as plastics.
The correct option is c.
Wood may be replenished by planting new trees to replace those being used.
Explanation:
This is because wood is a Renewable resource because Renewable resources are resources that can be replenish or reproduce again after usage either by naturally producing another one. Theses resources are not exhausted because they can naturally be reproduce again. Wood is a Renewable resources because new ones are planted to replaced the used ones.
Why does sodium and potassium ions need a protein pump to pass through the cell membrane?
A. The ions have a charge and cannot pass directly through the cell membrane.
B. The ions are moving against the concentration gradient.
C. Energy is needed to move the ions.
D. All of the above.
Cell membrane have been the selective membrane that allows transportation. Sodium and potassium ions need a protein pump as they are charged particles that move against the gradient and need energy. Thus, option D is correct.
What is active transport?Active transport has been the way to move ions and molecules inside and outside the cell membrane. This system of transportation requires energy as the ions move from low concentration regions to the region of the higher electrochemical area.
The sodium and potassium pump needs proteins and energy to move the ions as the inside of the cell is rich in potassium and the exterior is rich in sodium ions. The charged ions moving against the concentration cannot enter the cell without energy and protein pumps.
Therefore, option D. all of the above statements are correct.

Explanation:
hope this helps :)
A spore grows into a mature gamete producing plant is best describe the life cycle of fern.
What is the life cycle of fern?The life cycle of the fern has two different stages such as sporophyte and gametophyte. The sporophyte stage which releases spores whereas gametophyte stage which releases gametes. Gametophyte plants are haploid whereas sporophyte plants diploid. This type of life cycle is known as alternation of generations.
So we can conclude that a spore grows into a mature gamete producing plant is best describe the life cycle of fern.

If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.

A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
Answer:
the first option
Explanation:
As the soil gets darker, brown beetles become easily recognised by predators (like birds) and will be eaten. Black beetles however, are better camouflaged and will less likely be spotted by the birds. Black beetles will survive and interbreed, allowing the recessive allele to be passed on to upcoming generations.
Selective pressure is what makes the genetic pool shift toward a particular genotype with a particular phenotype (recessive black in this case) that gives the new generations a selective advantage. They're more likely to survive and reproduce. Survival of the fittest.
Genotype- the genetic makeup of an organism (eg: the recessive gene for black; bb)
Phenotype- physical feature of an organism as determined by the genotype (the colour black)
Selective pressures will increase the number of brown beetles. The correct option is 2.
What is Selective pressure?Any factor that reduces or increases reproductive success in a subset of a population may exert evolutionary pressure, selective pressure, or selection pressure, thereby driving natural selection.
Selection pressure can be defined as a force that causes an organism to evolve in a specific direction.
It is not a physical force, but rather an interaction between natural variation in a species and environmental factors that causes certain forms to have an advantage over others.
A beetle species can be either black or brown in color. A single gene determines the color of the beetle, and black is recessive to brown.
The soil in the area has darkened and taken on the color of black beetles. Brown beetle populations will increase as a result of selective pressures.
Thus, the correct option is 2.

Deforestation leads to environmental imbalance. Give reason.
Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

A student crested a model to show the flow of energy in a terrestrial ecosystem.
Which of the following correctly describes the way energy enters and leaves the ecosystem?
A Energy enters the ecosystem as sunlight, which is used by plants to produce sugars Energy leaves the ecosystem as heat from plants, herbivores, carnivores, and decomposers
B Energy enters the ecosystem from decomposers and is used by plants to produce sugars Energy leaves the ecosystem during cellular respiration
C Energy enters the ecosystem when it is transferred from the herbivores to the plants. Energy leaves the ecosystem as heat from plants, herbivores, carnivores and decomposers
D Energy enters the ecosystem as sunlight, which is used by plants to produce sugars. Energy leaves the ecosystem as mineral nutrients
The flow of energy in the terrestrial ecosystem is initiated by the sun and its flows to plants and then animal life and finally reaches the decomposers. Thus the option A is correct.
What is an ecosystem?An ecosystem is an ecological unit and its function is to balance the flow of energy in the environment. The flow of energy is unidirectional and as energy flow in one direction, it cannot be destroyed completely as it changes its form.
The energy that is received from the sun is transferred to the green plants, they include this energy to animals that are producers to consumers that include primary consumers and secondary consumers to decomposers, and then this energy leaves the system.
