Answer:

The acquired immune system produces special molecules (known as antibodies) with the help of immune cell system that protects the body against a specific intruder. After the body has been exposed to the invader, cells called B lymphocytes produce antibodies. Antibodies remain in your child's system.

Answer:

A section of the spacecraft is slowly rotated in order to simulate the force of gravity.

Explanation:

The rotational force of the spacecraft makes an artificial sort of gravity, which can be altered by changing the speed of the spinning or by moving the rotating part further/closer to the center point of rotation.

Answer:

sister chromatids carry identical genetic make up all the time.

Answer:

A clade needs a derived characteristic. If mammals were a clade, their derived characteristic would be having hair.

The inference that can be deduced from both pictures is that the pictures simply talk about climate change and its impact.

Climate change simply means the ice melting, ocean warming, rise in sea level and the acidification of oceans.

In this case, the inference that can be deduced from both pictures is that the pictures simply talk about climate change and its impact.

The first picture is about the Santa that was in the North Pole melting and the second picture is about the impact of climate change on sharks.

Answer:

the weakness potential is for invasion of individual privacy.

Explanation:

Because a person's DNA reveals so much information about their physical state, it is sensitive information that must be carefully guarded.

Answer:

Synonyms in the genetic code exist and some species only use one synonym to get the same amino acid. The reason why the percentage is low in gene is because it does not involve a lot of processes compared to the proteins which undergo mRNA and tRNA to be coded as amino acids.

Explanation:

Answer:

What Do All Organisms Have In Common? All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

He would get a expected gene in a plant, for example. Purebred tall pea plants would most likely give off more tall plants, with little runts.

It gives a certainty to what you're doing, and getting more sellable/ useable products.

The change in allele and genotypic frequencies in a population is evidence of gene flow.

The term gene flow makes reference to the interchange of genetic material between individuals of two or more populations.

The gene flow generates a change in the allele and genotypic frequencies in the individuals of a population in equilibrium.

The gene flow may be due to migration and this phenomenon must be mediated by reproduction.

The corresponding codon for the mRNA that is transcribed is referred to as 3'-UCA-5'.

This is defined as a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid.

During transcription, the corresponding base for Adenine is Uracil, cytosine is to guanine and Thymine is to Adenine and 5'3' to 3'5'.

The corresponding codon for the mRNA transcribed is 3'-UCA-5'. The corresponding mRNA lacks the nucleotide base thymine (T).

mRNA may be defined as the molecules that carry the genetic information needed to make proteins.

During transcription, the template strand of DNA is transformed into the mRNA in the nucleus of the cell. mRNA consists of nucleotide bases Adenine, Guanine, Cytosine, and Uracil. Hence, the sequence of the strand gets reversed according to the template strand of the DNA.

Therefore, the corresponding codon for the mRNA transcribed is 3'-UCA-5'.

And the close orbit would either pull them towards earth resulting in a collision

or shoot them out of the orbit at insane speeds

in both case they will die..

as soon as they will enter the earth's atmosphere, they will be burned alive by the heat due to the friction between their body and the air around them when they will be in the process of collision.

even if they avoid all this, they will still either be burn to death or freeze to death on either side of the earth coz the suit is only suitable for a limited amount of time...

Water first-rate has significantly laid low with the presence of acid and base within the water. So answer is lake a: ph = 6.6; lake b: ph = 6.8.

The water isn't always precise for fitness whilst its exceptionally acidic or exceptionally basic. If the pH of water is almost impartial, this water is nice for consuming purpose. In the choice 3, each lake A and lake B has pH almost impartial so this water reasons no awful impact at the fitness of the human body. Highly acid water has low water first-rate because of the presence of metals which adversely have an effect on our body.

The pH degree of the water in rivers, lakes, and wetlands is critical to plant and animal life is 7.

Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient. The resulting ionic current, generated by the movement of charged ions through membrane channels, can be measured by patch-clamp methods.

Ion channels must be able to interact with the charged regions of the cell membrane so nutrients can enter the cell.

Ion channels are passages in the cell membrane that allow the passage of charged molecules such as

Ions pass from one side to the other of the cell according to the electrochemical gradient. In other words, they go from a place with high concentration to one of low concentration. But to do this, they need to interact with the charged regions of the membrane, which are the ion channels.

Ions channels are one of the ways that nutrients enter the cell.
