Answer:
Embryonic stem cells can be readily grown in culture and exhibit unique properties, including spontaneous differentiation into three germ layers in vitro or teratoma formation in vivo. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

RNA is a molecule with characteristics and a role similar to DNA. Why is RNA necessary for DNA to fulfill its function?
Answer:
Like DNA, RNA (ribonucleic acid) is essential for all known forms of life. ... Messenger RNA (mRNA) carries the genetic information that directs the synthesis of proteins. Some viruses use RNA instead of DNA as their genetic material. Most of the RNA, however, does not code for proteins.
The RNA necessary for DNA to produce proteins that do all work in the cell system.
Transcription:
It is the process by which DNA form mRNA via the RNA Polymerase.
This mRNA is translated into the proteins bythe Ribosome. tRNA bring Amino acids to the ribosomes to produce protein chain.Therefore, the RNA necessary for DNA to produce proteins that do all work in the cell system.

Aaron is learning about genetics in science class, and he made a list about what he learned
. An example of a trait is blue eyes
Genes are always passed from offspring to parents
• Traits can be common and uncommon in populations.
. Genes determine most physical traits
Aaron made a mistake on his list. Which of these statements fixes Aaron's mistake
Answer:
Genes are always passed from offspring to parents
Explanation:
Well parents pass on genes to an offspring for one for another the parent will not always pass a gene for a certain trait on, if the trait is not a dominate gene it has the chance of getting replaced by the other parent's more dominate trait

Mendel chose to study pea plants for their diversity. Give an example of an organism that would be difficult to use in the study of genetics. Justify your response in two or more complete sentences.
Answer:
Female Lions
Explanation:
I believe this would be a difficult organism to use in the study of genetics, because for years all Lionesses have looked extremely similar to us humans. While Male lions have a lot of differences from each other. Although, what could be studied is how they pass on their traits to their offspring.

root hair cells have a high ion concentration . explain how this is maintained and its importance
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Explanation:
To maintain the concentration gradient and so the constant movement of water into the root hair cell by osmosis, the root hair cell actively transports mineral salts into the cell.
Root hairs are important because they absorb the majority of the water and nutrients required by the plant. The root hair cell actively transfers mineral salts into the cell to maintain the high ion concentration.
Root hairs, also known as absorbent hairs, are outgrowths of epidermal cells, which are specialized cells found at the root's tip.Root hairs are important because they absorb the majority of the water and nutrients required by the plant. In legume plants, they are also directly involved in the production of root nodules.The root hair cell actively transfers mineral salts into the cell to maintain the concentration gradient and hence the continual passage of water into the cell by osmosis.

Some bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. These drugs act as inhibitors to the bacterial enzymes but they target enzymes we don't have. Now, imagine you overhear your friend saying "antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!" Kindly explain to your friend (who has very little science background) how it is possible to target bacteria based on enzyme specificity. Be sure to include how targeting these enzymes is effective at stopping the infection.
Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.

Freshwater is recycled through the use of irrigation, bathing, and everyday use.
Freshwater is easily polluted or depleted before it can be replaced.
Freshwater evaporates and condenses, and then precipitation returns it to the lakes.
Freshwater is highly affected by global warming, and is quickly evaporating.

name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule
Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.
Transcription is the process that occurs in the nucleus.
What is the process that synthesizes the mRNA?mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.Therefore, transcription results in the formation of the mRNA.

Using all the words below, write a short paragraph explain convection currents
Convection Currents
Mantle
Crust
Heat
Less dense
movement
More dense
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.In order for materials to enter or exit any type of cell, it has to pass through the cell's selectively permeable barrier.
