Kelp forests are a very important ecosystem in marine waters by supporting important biodiversity. These kelp forests are threatened by all of the following except presence of large predators.

Kelp forests are an incredibly important marine ecosystem that provide a variety of benefits to the surrounding environment. They are a prime source of habitat and food for a large variety of species, including fish, invertebrates, and even certain species of seabirds. In addition, kelp forests also act as a type of buffer, protecting coasts from erosion and providing habitat for juvenile fish, which helps to maintain coastal fish populations. Unfortunately, kelp forests are threatened by many factors, including overfishing, pollution, and climate change.

The one factor that does not threaten kelp forests is the presence of large predators. While large predators can have a significant impact on the overall structure of a kelp forest, they are not directly responsible for the decline and destruction of kelp forests. For example, while sea otters, seals, and sea lions can have a significant impact on kelp forests by over-browsing, they are not the cause of the decline in kelp forests.

Positive mutations are essential for evolution to occur. They raise a living thing's chances of surviving or procreating. Deadly mutations can give rise to cancer or genetic diseases.

While most mutations are beneficial, some can also be dangerous. A dangerous mutation might cause a genetic illness or a cancerous condition. Chromosome-level mutations are still another type. Chromosomes, which are little, threadlike organelles present in the cell nucleus, carry genes.

A variation can make a protein malfunction or not be created at all by altering the gene's instructions for producing it. A variation can impair normal development or result in a disease when it changes a protein that is essential to the organism.

Given that whales and other mammals resembled other mammals in terms of their skulls and other sculptures, based on the fossil evidence, humans have undergone evolutionary transitions.

The transition from land animals to whales is one of the most well-known instances of a supposed change cited by the evolution contingency in the opening of the program. The fossils of Pakicetus, Ambulocetus, Rhodocetus, Dorontid, and Basilosaurus show that this transition can be explained. Pakicetus only has a small portion of its cranium to display, as opposed to a whole transitional fossil.

The program portrays Ambulocetus as a fully preserved fossil of an aquatic mammal with legs, yet this is a stretch of the fact because the animal's skeleton was actually discovered to be extremely fragmented. Rhodocetus is solely represented in the series by a skull.

The specific colors of light that a leaf reflects depend on the pigments present in the leaf. Chlorophyll, which is the pigment primarily responsible for the green color of leaves.

leaf reflects green light and absorbs other colors of the visible spectrum such as blue and red. Carotenoids, which are pigments that give leaves their yellow and orange colors, leaf reflects yellow and orange light. And finally, anthocyanins which are pigments that give leaves their red, purple and blue colors, leaf reflects red, purple and blue light. Additionally to these pigments, other substances on the leaf surface can also affect the light leaf reflects. It's worth noting that while leaves reflect visible light, they also reflect other types of light such as near-infrared and ultraviolet, but these are not visible to the human eye.

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not.

Hope this helps! ;)

D. The cell then has a larger surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently.

Explanation:

Natural selection, genetic drift, and gene flow are mechanisms that cause changes in allele frequencies over time, contrary to the Hardy-Weinberg assumption, and evolution occurs.

Evolution refers to changes in the genetic composition of a population of organisms over time. There are four forces that work together to effect evolution: mutation, natural selection, genetic drift, and gene flow. First, natural selection is a mechanism by which organisms with beneficial traits become more likely to inherit those traits, increasing the population of the next generation.Genetic drift results from random changes in allele frequencies. , these changes may restore or promote genetic diversity. Gene flow is the exchange of genes between populations by migration or mating, which can introduce new alleles and introduce genetic variation into populations. Ultimately, mutation produces genetic variation by spontaneously forming new alleles.

Explanation: Every other  choice can be changed with environment and other factors but DNA can effectively compare organisms.

The occurrence of transitional fossils supports the idea that - extinct and living forms are related, these are ancestors of living species, change occurs in species over time.

A transitional fossil is that  fossilized remains of a life form which exhibits traits common to both an ancestral group and its derived descendant group which is living at present. The descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group.

These fossils show that taxonomic divisions are human made that have been superimposed on the continuum of variation. Because of the incompleteness and unavailability of the fossil record, there is usually no way to know exactly how close a transitional fossil is to the point of divergence if evolution of that particular species. Therefore, it cannot be assumed that transitional fossils are direct ancestors of more recent groups, though they are frequently used as models for such ancestors.

Coumarin is found to restrict the production of a specific component found in the cell walls but not in the cytoplasm, which plays an important role in the growth of the stem. (BIOSYNTHESIS< CYTO< STEM GROWTH)

The results from the experiment suggest that coumarin treatment negatively impacts the growth of plant seedlings, as measured by seedling height. This indicates that coumarin has an inhibitory effect on stem growth.

Additionally, the experiment that measured the number of radioactive labels in cytoplasmic and cell wall fractions revealed that coumarin affects the biosynthesis of a specific component in the cell walls but not in the cytoplasm. This suggests that coumarin specifically targets the production of a component that is critical for stem growth, and that this component is found primarily in the cell walls and not in the cytoplasm.

This is further supported by the fact that the radioactive label is found in the cell wall but not in the cytoplasm, indicating that the biosynthesis of this component is taking place in the cell wall and not in the cytoplasm. Overall, these results suggest that coumarin is inhibiting the biosynthesis of a component that is critical for stem growth, specifically in the cell walls.
