Compare characteristics of severe weather conditions for thunderstorms tornadoes hurricanes and cyclones
Explanation:
Thunderstorms:
A thunderstorm is produced by a cumulonimbus cloud, or thunderhead, that includes rain showers, lightning, and thunder.
They start when the sun heats the earth's surface and warms the layer of air above it. This warmed air rises and transfers heat to the upper levels of the atmosphere. As the air travels upward, it cools and the water vapor contained within it condenses to form liquid cloud droplets. As air continually travels aloft in this way, the cloud grows upward in the atmosphere, eventually reaching altitudes where the temperature is below freezing. Some of the cloud droplets freeze into ice particles, while others remain "supercooled." When these collide, they pick up electric charges from one another; when enough of those collisions happen, the big buildup of charge discharges, creating lightning.Thunderstorms are most hazardous when rain decreases visibility, hail falls, lightning strikes or tornadoes develop.
Tornadoes:
tornado is a violently rotating column of air that extends down from the base of a thunderstorm to the ground.
When wind near the earth's surface blows at one speed and wind above that blows at a much faster speed, the air between them whips around into a horizontal rotating column. If this column gets caught in the thunderstorm updraft, its winds tighten, speed up, and tilt vertically, creating a funnel cloud.Tornadoes are dangerous—even deadly—because of their high winds and subsequent flying debris.
Hurricanes:hurricane is a swirling, low-pressure system that develops over the tropics with sustained winds that have reached at least 74 miles per hour.
Warm, moist air near the ocean's surface rises upward, cools, and condenses, forming clouds. With less air than before at the surface, the pressure drops there. Because air tends to move from high to low pressure, moist air from surrounding areas flows inward toward the low-pressure spot, creating winds. This air is warmed by the ocean's heat and the heat released from condensation, so it rises. This starts a process of warm air rising and forming clouds and surrounding air swirling in to take its place. i hope helps u marks as brainlist

Oxygen atoms normally have 8 protons, 8 neutrons, and 8 electrons. An isotope of
oxygen with an atomic mass of 18 would have two extra
Charged particles
Neutrons
Protons
Electrons
Answer:
The answer is Neutrons
An isotope of oxygen with an atomic mass of 18 would have two extra Neutrons. Hence, option B is correct.
What is an isotope?Isotopes are atoms with the same atomic number but different atomic masses. In other words, atoms having the same number of protons but different numbers of neutrons are called isotopes. Although isotopes have highly similar nuclear properties, they have equivalent chemical properties.
For instance, hydrogen has three isotopes. While tritium (one proton and two neutrons) is radioactive, the other two isotopes are unstable. Stable isotopes exist for most elements. For several elements, radioactive isotopes can also be produced. When compared to lighter isotopes of the same element, heavier isotopes often react more slowly.
An isotope has a different number of neutrons. Therefore, option B is correct.

If two heterozyotes for dwarfism have children what proportion of their kids would you expect to be of typical size and not exhibit dwarfism?
Answer:
3/4 or 75%
Explanation:
This question involves a gene coding for height in humans. The allele for normal height (D) is dominant to the allele for dwarfism (d).
If two heterozygotes for dwarfism are crossed i.e. Dd × Dd, the following gamete will be produced by each heterozygote parent:
Dd - D and d
Using these gametes in a punnet square (see attached image), the genotypes of the expected offsprings will be as follows- DD (1) : Dd (2) : dd (1)
(1) DD - typical normal size
(2) Dd - heterozygous normal size
(1) dd - dwarf
The offsprings expected to be of typical size and not exhibit dwarfism are offsprings DD and Dd, which represent 3/4 of the offsprings. Hence, the proportion is 3/4 or 3/4 × 100 = 75%.

c. Stratum lucidum
d. Stratum basale
e. Stratum spinosum
1. : Deepest layer; site of rapid cell division and melanin production
2. : Live keratinocytes connected by desmosomes produce pre-keratin
3. : Cells flatten and fill with keratin, resulting in a grainy appearance
4. : Clear layer found only in thick skin; cells full of keratin
5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff
Answer:
a. Stratum corneum 5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff.
b. Stratum granulosum 3.: Cells flatten and fill with keratin, resulting in a grainy appearance.
c. Stratum lucidum 4. : Clear layer found only in thick skin; cells full of keratin.
d. Stratum basale 1. : Deepest layer; site of rapid cell division and melanin production.
e. Stratum spinosum 2.: Live keratinocytes connected by desmosomes produce pre-keratin
Explanation:
The epidermis has five layers, starting from the deepest one they are:
The stratum basale: is the layer that has the germinative cells, called keratinocytes.
The stratum spinosum: the keratinocytes are connected, and they produce the precursor of keratin and lipids.
The stratum granulosum: the name of this stratum is due to the appearance of the cells. They produce keratohyalin, and the lipids produced in the previous layer are released, creating the layer that protects the skin against dehydration.
The stratum lucidum: They are only in thick skin, like the one that is in the sole of our feet. The cells do not have a nucleus. They are filled with keratin, which is the component of thick skin.
The stratum corneum: the more superficial layer, it is made of dead cells filled with keratine. When new cells ascend to this stratum, the old ones have to be removed by exfoliation or natural peeling.
The five distinct layers of the epidermis with different features and roles are given below: a) Stratum corneum- 5, b) Stratum granulosum- 3, c) Stratum lucidum- 4, d) Stratum basale-1, e) Stratum spinosum- 2.
The epidermis (outer layer of the skin) is the part of the skin that’s visible to the unaided eye and works to protect the body. The epidermis doesn’t have any blood vessels, so it relies on the dermis (the layer of skin directly beneath the epidermis) for nutrients and waste disposal.
The epidermis protects the internal organs, the muscles, the nerves, and the blood vessels. The epidermis also creates new skin cells and produces melanin, which gives the skin its color and reduces the absorption and effect of UV radiation. It protects the body physically, and it also protects the immune system.

Viruses use a host cell to replicate their genome.Viral replication can exponentially increase virus numbers. Viruses destroy host cells upon their release from the cell.Thus, the correct options are A, C, and D.
What is the Lytic cycle?The lytic cycle may be defined as a type of cycle that involves the process of lysis and destruction of the infected cell and its membrane. This process occurs when a virus has completely infected a cell and replicates new virus particles by the activity of bursting the cell membrane.
The lytic cycle is considered one of the two cycles of viral reproduction, the name of the other is the lysogenic cycle.
During the lytic cycle, the virus uses a host cell to replicate its genome. After occupying the host cell for the same activity, viral replication can exponentially increase virus numbers. And finally the destruction of cells and release themselves from the cell.

Which option contains all of the other options listed?
gene
chromosome******
chromatid
centromere
Answer:
The chromosome contains all of the other options listed.
Explanation:
In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNI molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA. DNI associated with histones is called chromatin. Histones are responsible for packaging the DNI molecule.
In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state. When cellular division is about to happen, chromatin begins to condensate, and the chromatin strand generates a copy or clon so both of the daughter cells can get the same genetic information. At the beginning of the prophase, DNI is condensed in a well-defined chromosome formed by two sister chromatids. In metaphase, two chromatids joined by a centromere form the typical chromosome.
So, one chromosome is composed of two sister chromatids condensated and joint by the centromere. It looks X-shaped.
Genes are located in chromosomes, specifically in the DNA strand.

Answer:
B: Embedded within the hydrophobic and hydrophillic regions of the bi layer
Explanation:
They are integral protiens and have to be inside
i took a test
This movement aids the cell membrane in preserving its function as a partition separating the interior and exterior cell surroundings. Thus option B is correct.
What is the role of transport protein in fluid mosaic model?Integral proteins protrude from each end of the phospholipid bilayer and are tucked inside. Larger molecules like glucose can be transported through cell membranes with the aid of integral proteins.
They have sections that match the polarity of the phospholipid bilayer, known as "polar" and "nonpolar" regions.
This movement aids the cell membrane in preserving its function as a partition separating the inside from the outside environments of the cell.
Therefore, in the fluid mosaic model, the transport protein is connected to the phospholipid bilayer's outer layer.
