Why do heart cells have different characteristics than skin cells?
Heart cells have different DNA than skin cells.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Heart cells reproduce by mitosis.

Answers

Answer 1

Answer:

Heart cells express different genes than skin cells. B

Answer 2

Heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.

Humans as multicellular organisms possess different cells in our body system. These cells perform varying functions in the body.

The different functions performed by different cells is attributed to the cellular differentiation. Cellular differentiation is the process whereby an undifferentiated cell becomes specialized.

The cellular differentiation occurs due to the difference in gene expression in each specific cell. All cells contain the same DNA sequence, however, they are expressed differently.

Therefore, heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.

What part do plants play in the water cycle?

Answer:

The correct answer is -

- The characteristics of the water cycle are evaporation, transpiration, condensation, precipitation, surface runoff, and groundwater.

- Plants perform transpiration.

Explanation:

The water cycle is the movement of the water in between different spheres of the earth that include the atmosphere, hydrosphere, geosphere and biosphere. The water cycle has various components and processes that complete the water cycle and connect different spheres.

The components of the water cycle are evaporation of water and transpiration from the hydrosphere or geosphere and plants respectively to the atmosphere.

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.

The epidermis is the most superficial layer of the skin. It is composed of stratified squamous epithelium. Within the epidermis, there are five distinct layers with different features and roles. Match the appropriate skin layer with its description.

a. Stratum corneum
b. Stratum granulosum
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

Answers

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.

.Explain why the scientific process is important when learning about diseases.

Answers

Answer:

The scientific process is important when learning about diseases because it allows to obtain reliable and valid knowledge about the different existing diseases, it helps in solving problems correctly and it is the best tool to nullify arbitrary opinions regarding a diagnosis or treatment, taking into account each of its stages.

Explanation:

The scientific method is a process through which relationships between facts are established to arrive at the verification of something. Through this step by step in which facts are discarded and added, the answers to findings are based. It is through the information generated by the research that it is possible to associate and / or integrate a set of symptoms and signs with a probable nosological diagnosis. Similarly, the selection of treatment and even the prognosis of patients depend on the information obtained from a population of subjects who share attributes; they depend, in a word, on research. Bearing in mind the scientific process, scientific thinking develops with practice, and for this it is necessary that there be constant reflection on the problems, have guides for the interpretation of medical reading, develop research protocols, learn to collect and analyze data about diseases.

Scientific is very important in order to obtain information about the disease.

The scientific process is important when learning about diseases because it provides information about various aspects of diseases as well as provides solution about cure of the disease.

This scientific process or method can be used for obtaining information about the causes of disease, its causing agents and cure for the disease so we can conclude that scientific is very important in order to obtain information about the disease.

Compare characteristics of severe weather conditions for thunderstorms tornadoes hurricanes and cyclones

Answers

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

You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying out this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.

Answers

Answer:

DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)

Explanation:

2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.

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.

Answers

Answer:

A. Phospholipid bilayer

Explanation:

Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.

The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
