Explanation:
As carbon dioxide is added to the atmosphere, more carbon dioxide also enters the ocean through diffusion. Carbon dioxide reacts with water to produce carbonic acid, which lowers the pH of the water. What effects do you think this might have on marine life?
Answer:
As the amount of carbon dioxide in the atmosphere rises, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid. This causes the acidity of seawater to increase.
As we have seen, coral reefs have been bleached because of this increased in acidity
The oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.
What is acidification?Acidification is defined as a phenomena that happens when some chemicals release protons into the environment. Ocean acidification is mostly brought on by atmospheric carbon dioxide gas absorbing into the ocean. The pH of the water is lowered as a result, increasing the acidity of the ocean. The amount of carbon dioxide is rising due to numerous factors.
More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.
Thus, the oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.

Plasmodium is an organism with both sexual and asexual life cycles. Describe the most likely cause of a heritable phenotypic change in some members of a population of asexually reproducing organisms. Explain how repeated exposure of the artesunate-sensitive Plasmodium strain to increasing concentrations of artesunate led to the development of the artesunate-resistant Plasmodium strain.
Answer:
Mutation.
Explanation:
Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.
A unicellular eukaryotic organism that infects and lives in insects and vertebrates as a parasite is called plasmodium. They are single-celled organisms that undergo both types of reproductive life cycles.
The mutation caused a heritable phenotypic change in some members of a population of certain type of reproducing organisms.
The mutation in the plasmodium strain can be explained as:Some organisms of certain reproducing type happened to be mutated causing a heritable phenotypic change in their offspring's. When the plasmodium strain was repeatedly exposed to artesunate which altered some of the species in becoming resistant instead of being sensitive.The increased dosage or exposure caused a mutation in some type of certain reproducing strains causing them to be resistant to the amount.Therefore, the mutation caused the heritable phenotypic change.

Select the correct statement(s) about angiosperm seeds. Select all that apply. Select all that apply. The embryo in an angiosperm seed is the offspring of the sporophyte plant. All structures in an angiosperm seed are diploid. An angiosperm seed contains structures contributed by three generations of plants.
Answer:
An angiosperm seed contains structures contributed by three generations of plants.
Explanation:
The spermatophytes, also known as phanerogams, represent a group of seeded plants that have developed special structures for reproduction. This group (spermatophytes) consists of gymnosperms or 'naked seeds', and angiosperms or 'enclosed seeds'. The seed is an organ generated from the ovule after fertilization by the pollen grain, which gives rise to a seedling during the process of germination. In flowering plants, seeds are generated by a process of double fertilization and consist of three tissues: 1-an embryo (generally diploid) formed by repeated mitotic division of the zygote cell, 2- an endosperm tissue (generally triploid, 3n) that nourishes the embryo during its growth, and 3-a seed coat generated from the integuments of the ovule. In angiosperms, seeds consist of three generations: the gametophyte that provides nutrients to the embryo, the embryo, and the seed coat which is generated from the parental tissue (sporophyte).

Pick out the sentences that correctly describe marine mammals.
Marine mammals are endothermic, or warm-blooded. Species such as whales breathe air though their gills. They have a thick layer of blubber
that helps maintain buoyancy. They can stay underwater indefinitely. Dolphins are a type of toothed whale. Baleen whales feed on large fish
and sometimes seals.
Marine mammals are endothermic. I think that's the correct answer 'cause they can produce their own body heat (which therefore means that they are warm-blooded) and they can keep at a stable temperature even in harsh conditions. Plus, whales don't have gills b/c they are mammals (and mammals don't have gills), not all mammals have blubber (it's mainly penguins and seals), marine mammals can stay underwater for a long amount of time...but they eventually need to come up for air, and baleen acts like a "filter"; it "filter" and separates the water from the krill/microorganisms.

Overpopulation
Survival of the Fittest
Underpopulation
Variation
Answer:
im pretty sure it is underpopulation.
Answer:
I think it's B. survival of the fittest since it's mostly just a phrase people say. I don't think underpopulation because, I'm pretty sure that's used when there not enough of an animal in an area, so while it could be the answer I don't think it is. And overpopulation is used when there's to much of an animal in an area so like with underpopulation it could be the answer but I do not think it is. And Variation is a step in Natural Selection so that's definitly not it. So since Survival of the fittest is mostly just a phrase people say I think that's the answer. Sorry for wasting your time if I'm wrong.
What are the products when a DNA molecule replicates?

B two molecules of DNA each made of a paired sequence of nucleotides
C two strands of DNA each made of a paired sequence of bases
D two strands of DNA each made of a paired sequence of nucleotides
(Its NOT c.)
The products when a DNA molecule replicates are two molecules of DNA each made of a paired sequence of nucleotides. The correct option is B.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The fundamental mechanism of DNA replication is similar across all organisms, making it a crucial operation.
Two DNA molecules, each consisting of a paired sequence of nucleotides, are produced when a DNA molecule duplicates.
Thus, the correct option is B.

In one or two paragraphs, compare and contrast surface ocean currents and deep water ocean currents in terms of causes and characteristics.
Please!!!
Answer:
Surface ocean currents
Surface currents refer to movement of the top layer of ocean water. Surface water flows in to replace the sinking water, which in turn becomes cold and salty enough to sink.
examples of surface ocean currents are California Current (Cal) in the Pacific ocean basin and the Canary Current (Can) in the Atlantic ocean basin.
Deep ocean currents
Deep-water currents describe water movement patterns far below the ocean’s surface and the influence of the wind. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.

A phenotypic ratio of 9:4:3 is indicative of __________.
A. Codominance
B. Polygenic inheritance
C. Epistasis
D. Multiple alleles
Answer:
a
Explanation:
The phenotypic ratio is the depiction and the relation of the occurrence of the phenotype in the offspring. The phenotypic ratio of 9:4:3 indicates codominance. Thus, option A is correct.
What is codominance?Codominance is the inheritance where both the recessive and the dominant allele are expressed in the offspring independently to produce the individual with the expression of both the trait separately.
The blood group, eye color, roan cattle, flower colors, sickle-cell anemia, etc., are some examples that show the pattern of codominance. The phenotypic ratio suggests the occurrence of the physical traits in the offspring that are visible.
In codominance, the phenotypic ratio is 9:4:3 as both the traits possessing alleles are independently expressed in the next generation.
Therefore, 9:4:3 is the phenotypic ratio of codominance.

How can beavers help dry areas? Fill in the inference in the chart.
Beavers help dry places by making dams. The correct inference is 2. Beavers are mammals and they are rodents.
What are beavers?Beavers are mammals and they are semiaquatic animals. They eat trees and other woody plants, apples, grasses, water lilies, clover, giant ragweed, cattails, and watercress are among the soft plants that beavers eat.
The water will be slowed down and allowed to soak into the earth, allowing beavers to create channels and plant trees. In times of drought, any leaks in beaver dams will gradually discharge water into the river, and ponds and wetlands will gradually release water into streams and rivers until they dry out.
