Surface water and groundwater levels increase.

(B) Surface water and groundwater levels decrease.

©

Surface water levels increase, while groundwater levels decrease.

Surface water levels decrease, while groundwater levels increase.

Answers

Answer 1

Answer:c

Explanation:

Answer 2

Increase in the surface water levels, while the decrease in groundwater levels is most likely to result at a river basin when a large amount of snow melts at the beginning of spring. Thus, the correct option is C.

What happens to river basin when snow melts?

Once the air temperatures begin to rise above 32°F, however, the snow and ice melts into liquid water and becomes runoff, which is the water that run of the land surface. This runoff then flows downhill through the mountains and this snow moves into lakes, rivers, and oceans. Some of the water which melt also soaks into the ground-level i.e., infiltration.

When a large amount of snow melts at the beginning of spring, the most likely results at the river basin will be the increase in the surface water levels while a decrease in the groundwater level.

Therefore, the correct option is C.

Answer:

A)Ocean floor evidence of sea floor spreading.

Explanation:

evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,

What is the tectonic theory?

The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.

What is a tectonic plate?

They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!

The plate tectonic theory gave the concept of land and sea formation. "Ocean floor evidence of seafloor spreading" acted as evidence to support the plate theory. Thus, option A is correct.

What is plate tectonic theory?

The plate tectonic theory states about the formation of the lithosphere by the movement of the plate tectonics located deep in the mantle and core layer of the earth. These plates show movement slides over each other to produce lands and drifts to form the oceans.

At a very early there was a supercontinent, Pangaea that slowly shows the formation of the current continent by the movement of the tectonic plates. These solid hard rocks of the earth layers allowed the formation of the various land formations.

The seafloor spreading is the best evidence that supports the tectonic plate theory that described the formation of the oceanic structures including the trenches and basins. The geological structures of the ocean floors supported the theory.

Therefore, option A. evidence of seafloor spreading supported the plate tectonic theory.

A single gene with two alleles control variation in haemoglobin type in sheep. There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4

Answers

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.

What is Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.

Assuming a diallelic gene,

Allelic frequencies

The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is q

Genotypic frequencies

p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example,

Alleles Frequencies

S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4

Genotypes

S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygous

We need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).

Genotypic and Phenotypic frequencies

F(S^AS^A) = p² = 0.6² = 0.36

F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48

F(S^BS^B) = q² = 0.4² = 0.16

Number of individuals expressing each phenotype

S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individuals

evolutionary significance of bryophytes

Answers

The bryophytes, which include mosses, liverworts, and hornworts, have significant evolutionary significance in the plant kingdom despite their relatively small size and simple structure, they played a crucial role in the colonization of terrestrial environments and the subsequent evolution of higher plants.

Here are some key evolutionary significance of bryophytes:

Adaptation to land: Bryophytes are considered some of the earliest land plants.

They were the first plants to transition from aquatic to terrestrial habitats, paving the way for the colonization of land by other plant groups.

They developed strategies to overcome challenges such as desiccation, limited nutrients, and anchorage to the soil.

Moisture retention: Bryophytes have adaptations that enable them to retain moisture.

They possess specialized structures, such as rhizoids and mucilage, that help absorb and retain water.

This ability to retain water and survive in relatively dry environments was an important adaptation for the conquest of land.

Soil formation: Bryophytes, especially mosses, contribute to soil formation.

They can grow on bare rocks and soil, where their rhizoids aid in weathering and breaking down substrates.

Their decomposed remains also contribute organic matter to the soil, enriching its fertility.

Habitat creation: Bryophytes provide habitat and microenvironments for other organisms.

Their dense mats or cushions create shelter, moisture, and temperature buffering for a variety of organisms, including insects, small invertebrates, and microorganisms.

They contribute to the overall biodiversity and ecosystem functioning.

Reproductive strategies: Bryophytes have unique reproductive strategies. They produce spores that can disperse and colonize new habitats.

Their reproductive structures, such as gametophores and sporophytes, exhibit various adaptations that allowed for successful reproduction in terrestrial environments.

Ecological indicators: Bryophytes are sensitive to environmental changes, making them valuable ecological indicators.

Their presence, abundance, and diversity can indicate environmental conditions such as air quality, moisture levels, and habitat disturbance.

Monitoring bryophytes can provide insights into the health and integrity of ecosystems.

Overall, bryophytes played a crucial role in the evolution and colonization of land by plants.

Their adaptations, ecological roles, and evolutionary history make them important subjects of study for understanding plant evolution, ecosystem dynamics, and the colonization of terrestrial environments.
