Why do your fingers look like prunes after swimming for a long time?

Alina [70]

Answer:

pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.

Cystic fibrosis is a genetic disease in humans in which the CFTR protein, which functions as a chloride ion channel, is missing

KiRa [710]

Answer:

ABC transporter protein

Explanation:

ABC transporter protein refers to the ATP binding cassette protein which utilizes the AT energy to transport the substrates from one side to another side. The ABC proteins are one of the oldest proteins known in the organisms.

The CFTR protein which acts as a chloride channel in the membrane which transports the chloride ions across the membrane utilizes the ATP energy in the transport.

Thus, ABC transporter protein is correct

Explain how mRNA is formed from the DNA template.

muminat

Answer:

mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

<em>The DNA sequences may vary but the amino acid sequences are identical. </em>
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.
