What is Natural selection

Biology
1 answer:
icang [17]3 years ago
7 0

Answer:

This term was created by Charles Darwin based off his research on evolution

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

During the cross-bridge cycle in muscle cells, myosin motors hydrolyze ATP as fuel to create a pulling force on actin fibers. Pl
exis [7]

Answer and Explanation:

In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When the muscle fiber membrane depolarizes, the action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane and releases calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin heads bind to the uncovered actin-binding sites forming cross-bridges, and while doing it ATP is transformed into ADP and inorganic phosphate which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin.  Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.

Sonja [21]

Answer:

1. Adenine

2. Thymine

Explanation:

These are the four nitrogen bases of DNA nucleotides. It's just something that you have to memorize in order to be able to successfully study DNA. In case you are asked which base pairs with which, always remember this saying about base pairs: A and T, and, G and C.

Have a nice day and please don't forget to give me Brainliest!

andrew11 [14]

Answer:

TAGTC

Explanation:

There are four different nucleotides in DNA: adenine, thymine, cytosine and guanine.

The bases pair like so:

A with T (adenine with thymine)

C with G (cytosine with guanine)

The DNA sequence given is :

ATCAG

Match As with Ts, Ts with As, Cs with Gs and Gs with Cs.

The sequence of nucleotides that would bond with the sequence above is:

TAGTC
