Answer:
Answered below
Explanation:
the plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma invaginates into the cytoplasm of the muscle cell (sarcoplasm). This forms membranous tubules that pass across the muscle cells.
Which phrase best describes the need for ion channels?
ions must be able to interact with the charged regions of the cell membrane
o ions need to be sheltered from interacting with the charged regions of the cell membrane
Oso nutrients may enter the cell
O so nutrients may exit the cell
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.
What are ion channels?
Ion channels are passages in the cell membrane that allow the passage of charged molecules such as
Sodium: Na+Potassium: K+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.

A particular triplet of bases in the template strand of dna is 5' agt 3'. The corresponding codon for the mrna transcribed is
The corresponding codon for the mRNA that is transcribed is referred to as 3'-UCA-5'.
What is a Codon?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).
What do you mean by mRNA?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'.

Think about how acids and bases would affect the water quality in the two lakes. which set of ph data would you expect to see based on your observations? lake a: ph = 4.5; lake b: ph = 7.5 lake a: ph = 8.3; lake b: ph = 3.7 lake a: ph = 6.6; lake b: ph = 6.8 lake a: ph = 10.2; lake b: ph = 1.7
Answer:
7.5
Explanation:
Its neutral and testless
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.
What is pH of lake water ?The pH degree of the water in rivers, lakes, and wetlands is critical to plant and animal life is 7.
Hence explained.

How does the genetic material on two sister chromatids compare?
Answer:
sister chromatids carry identical genetic make up all the time.
Why is the percentage similarity in the gene always lower than the percentage similarity in protein.
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.

Would a human with enough food and water and oxygen in a suit survive a full close orbit around Earth? I would think not because of all the space junk, but thats the only reason I can think of.
Explanation:
except that, their first problem is how to drink the water and eat the food provided while at the same time taking in oxygen...
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...
