Explanation:
Islands like St. George Island and Dog Island are common along all coastlines in Florida (Merritt Island is another example). Identify the coastal feature that these islands represent and describe the formation process of these islands.
Answer:
These islands are barrier islands.
Explanation:
Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.

The seed plants became dominant during the late ___ when the climate became ___.
The seed plants became dominant during the late Paleozoic era when the climate became drier and more arid.
The dominance of seed plants during the late Paleozoic era was driven by a combination of their unique reproductive strategies, water-conserving adaptations, and the changing climate that favored their survival and proliferation.
During the late Paleozoic era, which lasted from approximately 298 million years ago to 252 million years ago, seed plants, including gymnosperms and later angiosperms, became the dominant plant group on Earth.
This era is also known as the "Age of Seed Plants" due to the significant diversification and success of seed-bearing plants.
One of the main factors that contributed to the rise of seed plants during this time was the changing climate. The late Paleozoic era saw a shift towards drier and more arid conditions, with the decline of the swampy and humid environments that characterized earlier periods.
Seed plants have several adaptations that allowed them to successfully colonize and dominate these drier environments. One key adaptation is the ability to produce seeds, which are reproductive structures containing embryos and stored nutrients.

a. hyperoxidation.
b. methylation.
c. dephosphorylation.
d. phosphorylation.
e. integration.
Answer:
b. methylation.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their cytosine residues termed methylation.
For example, CpG island methylation transcriptionally silences about 650 to 800 genes in patients suffering from colorectal cancer.
The study of cells is cell biology.
The correct answer is B.

Answer:
Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary. During its transit inside the pollen tube, the generative cell divides to form two male gametes (sperm cells). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther.
Which of the following describes the consequences of overgrazing? (3 points)
I. Low precipitation
II. Desertification
III. Loss of arable land
IV. Soil erosion
O II, III, and IV
O I, II, and IV
I and II
O I and IV
Answer:
II. Desertifiction
The things that describes consequences of overgrazing are low precipitation, loss of land, and soil erosion. The correct option is A.
What is overgrazing?Overgrazing occurs when plants are subjected to intensive grazing for an extended period of time or without adequate recovery time.
It is caused by livestock in poorly managed agricultural applications, as well as game reserves and nature reserves.
Overgrazing can significantly decrease ground cover, allowing wind and rain to erode and compact the land.
This reduces the ability of plants to grow and water to penetrate, causing soil microbes to suffer and causing serious erosion of the land.
It is caused by livestock in poorly managed agricultural applications, as well as game reserves and nature reserves.
Thus, the correct option is A.

If the epidermis is such a good barrier, how can cortisone easily travel through it?
Answer:
cortisone is a lipid-soluble molecule hence can pass through the epidermis
Explanation:
Our adrenaline glands secrete various hormones including cortisol (also known as hydrocortisone) and corticosterone.
They belong to a group of steroid hormone bodies known as glucocorticoids and are used in a wide range of physiological processes such as inflammation regulation.
Pharmaceutical derivatives of these natural glucocorticoids include dexamethasone, fludrocortisone, prednisone, prednisolone, triamcinolone, which differ in strength. As all glucocorticoids have a similar effect, they all fall under the common name "cortisone".
William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
The diagram shows a chloroplast. In the light-dependent reactions, light strikes the thylakoids, water enters, and oxygen is released. In the light-independent reactions, carbon dioxide enters a cycle and sugars leave the cycle.
Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.
Explanation:
Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.
The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.
Can someone please help me? I don’t really understand this so could you explain?
Answer:
Explanation:
Hello amyrabogan90, The problem is mostly highlighting the distinct differences in both of the animals. By looking at the animals we can see that the rather large brown bear has evolved and adapted to its environment by growing a thick layer of fur and fat. This allows the bear to not only stay warm during the especially cold winters but go without eating for an extended period of time as sources of food become increasingly scarce. This starkly contrasts the qualities of the buck pictured on the left. Bucks are much slimmer and have a relatively light coat. This allows them to move quickly to avoid predators and allows them to stay alive on a herbivores diet of grasses and other vegetation. Bucks are also highly competitive with other males and can often be seen fighting each other for mating rights. For this reason the buck will grow a large set of antlers in order to fight with.

They have developed an effective camouflage. The pattern is actually part of the animal's skin so it appears below the fur as well. Tigers don't need protection from other animals, though they do need protection from human beings. The striped-coat camouflage serves to hide them from prey.

When using enzyme-linked immunosorbent assay to determine relatedness of species, what parameter is used to determine results?
Answer:
The change of color in the sample wells with the color in a known sample
Explanation:
Enzyme-linked immunosorbent assay (ELISA) is a technique widely used in molecular biology laboratories to measure antibodies, antigens and/or proteins in the samples that are being analyzed. This assay uses antibodies and color changes in order to identify target substances. The ELISA assay is heterogeneous because the antibody or the antigen is immobilized in a solid support composed by wells of microtiter plates. This assay uses chromogenic reporters and substrates that produce color changes, thus evidencing the presence of antigens which can be species-specific.
