You have a cup of vegetable oil and a vial full of normal phospholipids. What would you predict would happen if you dropped the
tino4ka555 [31]

The vegetable oil is made up of chains of long fatty acids. These long chains of fatty acids are non-polar in nature, i.e, they do not interact through ionic forces rather by covalent forces. The phospholipids are also long chain fatty acids with an ionic head. The mixing of the vial of phospholipid in vegatable oil will lead to the formation of a micelle where the lipophilic ends of the phospholipid will be on the outside and the lipophobic end will be towards the centre of the micelle.

Power stroke (myosin head bends) coupled with the release of ADP and phosphate, ATP hydrolyzed to ADP and Phosphate and the Myos
svetlana [45]

Answer:

Power stroke (myosin head bends) coupled with the release of ADP and phosphate

Explanation:

Muscle contraction results from myosin heads adhering to actin and attracting it inwards. It uses ATP. Myosin adhers to actin at a binding site of its globular actin protein and adheres at another binding site for ATP (hydrolyzed ATP to ADP, Pi  and energy)

ATP binding prompts myosin to detach from actin, ATP is changed to ADP and inorganic phosphate, Pi by ATPase. The energy formed at this process orientates myosin head to a “cocked” direction.

The myosin head goes in the direction of the M line, holding the actin with it in the process causing the filaments to orientate nearly 10 nm in the direction of the M line--- power stroke (force is produced), the sarcomere reduces in length and the muscle contracts.

Note: The power stroke is seen when ADP and phosphate disattaches itself from the myosin head.

At the terminal point of the power stroke, the myosin head as low-energy, followed by ADP release.

The attached image shows the cross-bridge muscle contraction cycle, which is activated  by Ca2+ sticking to the actin active site. And how actin moves in relation to myosin.

Imagine that a rancher has a herd of cattle with brown hides and short horns. All of his cattle are also relatively short in sta
dmitriy555 [2]

Answer:

The correct answer would be option D.

Explanation:

True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.

In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.

Thus, the correct answer is option D.

Give one reason why structure f(petal) is brightly colored in the diagram?
Marina CMI [18]

Answer:

petals are colorful because the color attracts birds, bees and other insects. The insects land in the flower and spread pollen, which helps fertilize the flowers and create seeds. Some flowers change color as they grow older.
