How is the temperature of a location determined by energy from
the sun and the location's distance from the equator?

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.

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.

A spore grows into a mature gamete-producing plant.

Explanation:

hope this helps :)

A spore grows into a mature gamete producing plant is best describe 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.

Answer:

Directional selection

Explanation:

occurs when natural selection favors one extreme of continuous variation. Over time, the favored extreme will become more common and the other extreme will be less common or lost.

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.

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.

Answer: Function. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A (retinol) is ingested as either retinyl esters or carotenoids and metabolized to active compounds such as 11-cis-retinal, which is important for vision, and all-trans-retinoic acid, which is the primary mediator of biological actions of vitamin A

Answer: By Snell's law, we can see that the angle of refraction is 30.34°

Explanation:

Snell's law says that:

If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:

n₁*sin(θ₁) = n₂*sin(θ₂)

We know that:

The incidence angle is 45°, then: θ₁ = 45°

We can assume that the first medium is air, then n₁ = 1

The refractive index of the other medium is 1.4, then n₂ = 1.4

Replacing these in the Snell's law equation we get:

1*sin(45°) = 1.4*sin(θ₂)

Now we can solve this for the angle of refraction:

sin(45°)/1.4 = sin(θ₂)

Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) =  θ₂ = 30.34°

So the angle of refraction is 30.34°

Answer:

D- Diagram 4

the full moon is represented in diagram four.

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%

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.

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%

Therefore, the percentage of the sample is made up of adenine, A is 28%

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

They're trace fossils, not animal bodies. This coprolite can reveal an animal's diet. Scientists can determine what animal dropped coprolites based on its shape, size, and location.

Fossilized feces are known as coprolites. Because coprolites provide information for the animal's behavior rather than its shape, rather than being considered body fossils, they are instead categorized as trace fossils.

 A coprolite  can provide researchers with information about an animal's nutrition. Scientists are able to determine the species of animal that may have been responsible for the droppings by analyzing the shape and size of the coprolites as well as the location where they were discovered.

Because coprolites have a propensity to deteriorate so quickly, we only find them very infrequently. They are the marine species that are found the most frequently. The presence of coprolites in fish and reptiles is very common.
