Limestone forms as ocean water evaporates and leaves calcium carbonate behind, which is then deposited on the ocean floor. what type of rock can be formed in this way?
Limestone is an example of sedimentary rock. It forms when ocean water evaporates and leaves calcium carbonate behind.
One of the most prevalent categories of chemical rocks is limestone. When calcium and bicarbonate ions erode from the remains of shells, coral, crustaceans, and mollusks in the water, they form limestone. These structures are gradually broken down by wave action into calcite and other calcium carbonate-based minerals, which build up in the ocean's water. These solutes can precipitate to form sediments rich in calcium carbonate as they are transported from the deep ocean environment to shallow areas like lagoons and tidal pools. For instance, calcium carbonate can precipitate in lagoons to form ooids, which are spherical nodules that cling together to form oolitic limestone, or limestone that has the shape of an egg.
Hence, limestone is forms link between living and non living.

The way that the factory affect the carbon and water cycle is that
The factory can affect the carbon cycle by releasing carbon dioxide into the atmosphere. Because carbon dioxide is a greenhouse gas , it can trap the Sun’s heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to infiltrate.What is a greenhouse gas simple definition?The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases (GHGs). The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.
Wherever carbon is delivered dissolved or suspended in flowing water, the two cycles directly interact. An essential component of carbon cycling, which is closely related to water flux, is the transport of organic matter and weathering products from the continents to the oceans.
Therefore, due to the fact that greenhouse gases like carbon dioxide, oxygen, and nitrogen keep the planet's temperature stable, they contribute significantly to global warming.

Recessive epistasis occurs when the recessive allele of one gene is epistatic over the other gene. The resulting phenotypic ratio is 9:3:4. In the exposed example, the phenotype of the aabb dog is yellow. Option A.
What is epistasis?Epistasis means interruption and refers to interactions between genes located in different loci in the same chromosome.
An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.
Epistasis might be either dominant or recessive,
When the epistatic gene is dominant, the interaction is known as dominant epistasis.The phenotypic ratio resulting from dominant epistasis is 12:3:1.
When the epistatic gene is recessive, the interaction is known as recessive epistasis.The phenotypic ratio is 9:3:4.
The exposed situation is an example of recessive epistasis, in which two diallelic genes affect the dog's fur color,
B is a dominant allele that codes for black color.b is a recessive allele that codes for brown color.A is the dominant allele that allows the expression of pigment.a is the recessive allele that that inhibits pigment expression. In this case, fur is yellow.The presence of at least one A allele is enough to express black (BB or Bb) or brown (bb) color. The absence of the A allele inhibits pigment expression.
The possible genotypes and phenotypes are,
AABB, AaBB, AaBb, AABb ⇒ Black AAbb, Aabb ⇒ BrownaaBB, aaBb, aabb ⇒ YellowAs we can see in the Punnett square, the phenotypic ratios are 9:3:4

The movement of molecules across a cell membrane known as passive transport occurs without the use of cellular energy.
Special compounds can pass through plasma membranes to enter and leave the cell, keeping out dangerous substances and allowing in only necessary substances. Selectively permeable, plasma membranes let some compounds pass through while preventing others. If they abandon this selectivity, the cell won't be able to strengthen itself and would perish.

species that undergo sexual selection often have males and females that differ dramatically in phenotype, a phenomenon called sexual dimorphism. since sexual dimorphism is a result of selection for the two extremes of a phenotypic trait, what pattern of selection is this?
Option A disruptive is the correct answer. This pattern of selection is disruptive because it favours the two extremes of a phenotypic characteristic, which results in sexual dimorphism.
Sexual dimorphism is the systematic shape difference between individuals of different sexes within the same species. For instance, the male in some species, such as many animals, is bigger than the female. The female of some species, like some spiders, is larger than the male. This sexual dimorphism has been noted in early development studies, childhood, adolescence, and maturity. On average, males' total brain size is around 8%–15% greater than females' (uncorrected for body size).

Explanation:
The RNA transcript is produced by transcribing the DNA sequence into RNA using the enzyme RNA polymerase. During transcription, RNA polymerase reads the DNA sequence and uses it as a template to synthesize the complementary RNA sequence. Because RNA is single-stranded and DNA is double-stranded, the RNA transcript is complementary to the non-template strand of the DNA, not the template strand.
In the given DNA sequence, the non-template strand would be:
