Well, you can’t clone a baby but, not exactly should you be allowed to do it. Could you clone an alive baby? Yes. There's two specific skills that infertility doctors have that are necessary for cloning. One is micro-manipulation of embryos. In this case, to take a human egg, to remove the nucleus, and then to replace that nucleus with a nucleus from a somatic cell, a body cell of the person who is going to be cloned.

if a couple clone a baby ,  There's two specific skills are taken by infertility doctors have that are necessary for cloning. One is micro-manipulation of embryos.

cloning can be defined as the process of producing genetically and phenotypically same organism or cells from a single organism/cell,

the process can be occurred  either naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.

Artificial cloning's can be up different types such as Reproductive cloning

Gene cloning, Therapeutic cloning

Reproductive cloning produce genetically identical organisms from a particular organism whereas gene cloning involves producing exact copies of a gene or segments of DNA.

Therapeutic cloning involves the production of embryonic stem cells and  create tissues that would replace similar but damaged or worn-out tissues in living organisms.

Answer:

i think it's b( I'm not 100% sure)

Answer:

Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.

the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.

Explanation:

mark it as brainliest. thnku hope it is helpful.

Explanation:

at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure

Answer: Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA

Explanation:

Cells are the smallest functional unit of organisms which are classified under two main categories namely:

--> prokaryotic cells and

--> eukaryotic cells.

Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.

Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.

From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.

Answer:

Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots.

Explanation:

The cycling of matter and the flow of energy within ecosystems occur through interactions among different organisms and between organisms and the physical environment. ... Energy from light is needed for plants because the chemical reaction that produces plant matter from air and water requires an energy input to occur.

PROVIDES INSTANT ENERGY TO THE BODY:

This appears to be the primary function of carbohydrates in the body.

Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.

RESERVE FOOD:

Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.

CARBOHYDRATES FORM OTHER BIOMOLECULES:

Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.

DETOXIFICATION OF THE BODY BY METABOLISM:

Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.

SPARING PROTEIN

In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

Answer:

10. Human Activity

Human activities emit 60 or more times the amount of carbon dioxide released by volcanoes each year.

11. Cooling Effect

When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.

12.  

The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.

13.

Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. ... But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

When they lose their leaves they need much less resources to survive (because they don’t need nutrients to support the leaves). For example trees lose their leaves in the winter because the ground freezes up and it’s harder to suck up nutrients.

Explanation:

I ecosystem must contain these if it doesn't then its not an ecosystem so yea hope this helps you :) bye ;)

Producers, consumers and decomposers are found nearly all ecosytems.

An ecosystem is a region where different species of plants, animals, and other organisms coexist in harmony with the environment, including the climate and geography.

An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors.

Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors. Along with rocks, temperature and humidity are abiotic variables.

Every component of an ecosystem is directly or indirectly dependent upon every other component.

Therefore, Producers, consumers and decomposers are found nearly all ecosytems.

Answer:

This child has learned to act from its adults.

Explanation:

This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.

Explanation:

Secondary consumers are the animals that eat the primary consumers.

They are heterotrophs, specifically carnivores and omnivores. Carnivores only eat other animals. Omnivores eat a combination of plants and animals. They are typically small to medium animals like lizards, robins, and frogs. Secondary consumers are usually not the last organism in a food chain. They are often eaten by large predators, the tertiary consumers.
