Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
Answer:
Explanation:
Firstly, let us break down the components:
A cilia is a hair-like structure positioned on a tissue for locomotive purposes
Epithelium is a type of tissue
Therefore, a ciliated epithelium is a kind of tissue that contains hair-like structures called cilia for locomotion. They can be found in our respiratory tracts lining, the fallopian tube of human females, brain etc. where they mainly perform the function of moving particles.
They help move foreign particles like dust from our respiratory tracts, they help move the egg from the ovary to the uterus of women, they also move cerebral spinal fluid in the brain.
Ciliated epithelium contains goblet cells, that secretes mucous to provide the moist medium for locomotion
Answer:
B
Explanation:
During asexual reproduction, the parent essentially clones their DNA to make their child. This means that there is very little possible variation, except for some occasional mutations. However, during sexual reproduction, the child gets the copy of DNA from both of their parents, and their features a mixture of their parents. This makes them not identical to either parent, unlike asexual reproduction. Therefore, the correct answer is choice B. Hope this helps!
Correct answer is B!

If you see meaning of "Unconditioned stimulus", you will see the right answer, firstly what does "Unconditioned Stimulus" means, it means any stimulus that naturally evokes a specific response; see also conditioning. If I would go with choices I would choose correct answer B.

Answer: Lymphatic capillaries are dead-end tubes.
Explanation: Lymphatic capillaries are closed tubes with flap-like valves that open to take in tissue fluid. Blood capillaries are part of a continuous system of blood vessels; arterioles supply blood to the capillary bed, and venules drain them.
