Answer:
The correct answer is - convergent evolution.
Explanation:
The convergent type of evolution involves the process in which non-related organisms evolved independently and still develop similar kinds of traits or structures due to factors such as ecological or environmental conditions. This environmental condition could be an ecological niche or issues faced by the organisms which force them to adapt accordingly.
For example, dolphins and shark look similar but are different organisms. Analogous organs or structures arise due to the convergent evolution as they have different ancestry still shows structures similar to one another.

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".

explain any two specific adaptation that allow animal to survive in Mountain habitat
Answer:
Among others, two adaptations might be
Avoiding corporal heat lossIncreasing oxygen absorptionExplanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
Avoiding heat loss. Temperature tends to be very low at highs, so, to avoid heat loss, animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate. Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown. Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements. Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.If a gamete contains 24 chromosomes, how many chromosomes would the somatic cells contain?

What are two conditions you need for air mass formation?
Hills/Moisture
Flat Terrain/Same Moisture
Hills/Rivers
Mountains/Lakes
Answer:
Flat terrain/same moisture
Explanation:
Ive done a test that had this question and got it right.
The two conditions you need for air mass formation are flat terrain and same moisture. The correct option is B.
What is air mass formation?It is Known as source regions, air masses form over large surfaces with uniform temperatures and humidity.
Low wind speeds allow air to remain stationary for long enough to absorb the characteristics of the source region, such as heat or cold.
When the atmosphere comes into contact with a large, relatively uniform land or sea surface for a long enough period of time, the temperature and moisture properties of that surface are acquired. The major air masses on Earth originate in polar or subtropical latitudes.
Air masses form over large surfaces with uniform temperatures and humidity, which are referred to as source regions, as well as flat terrain and the same moisture.
Thus, the correct option is B.

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.

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.

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.

Blended inheritance assumed traits:
O Were passed on intact
O Were diluted over time
O Were the result of learned skills
O Were incompatible with evolution
Answer:
O Were diluted over time
Explanation:
Blending inheritance is an outdated theory about inheritance that is no longer accepted.
The theory is that offspring inherit any characteristics as the average of the parents. For example, if a father had black hair and a mother had blonde hair, the child would have brown hair.
We now know, thanks to Mendel's work on inheritance, that the inheritance of characteristics are not so simple!
