<h2>Muscle contraction in cytoplasm </h2>
Explanation:
- Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
- ATP is basic to get ready myosin for official and to "revive" the myosin.
- When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
The answer is B)
The Golgi apparatus is located in the cells. It is an extra combination of organelle similar to the ER. This was named following Camillo Golgi.
(Notice that his last name is Golgi)
Answer:
Yes, the species of a lizard can be identified using dichotomous keys.
Explanation:
A dichotomous key is an identification tool used by the biologists especially taxonomists to identify and classify the organisms.
The dichotomous keys are based on the characteristic feature of an organism for which two which contains two contrasting feature. The dichotomous keys are the most common tools used to classify an organism.
A species of lizard can be identified using these keys by selecting the key characteristic feature shown by the species which could be quantitative like weight, height or it could be qualitative like colour. By comparing these characteristics, it becomes easy to identify the species.
Answer:
All EeWw (100%)
Explanation:
This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for earlobe but homzygous recessive for hairline i.e. (EEww).
The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:
eeWW - eW, eW, eW, eW
EEww - Ew, Ew, Ew, Ew
Using this gametes in a punnet square, the following proportion of offsprings will likely be produced:
All EeWw
