"B" is the correct answer

Answer:

B. Slow twitch fibers contain more mitochondria than fast twitch fibers.

Explanation:

The slow-twitch muscle has a characteristic red color, this is because is rich in myoglobin and mitochondria. Also is dense in capillaries. It uses an oxidation reaction involving oxygen and fat or carbohydrates. This fibers contract with little force but for long periods.

The fast-twitch muscle has great strength but can only hold it for short periods. It is called white muscle because is less dense in mitochondria and myoglobin and work with anaerobic reactions.

The muscles in your body are a mixture of both types.

Taking into consideration all this, A, C, and D are false, and B is true.

Describe how Schwann cells form the myelin sheath and the neurilemma.
-Dominant- [34]

Answer:

Schwann cells or neurilemma cells are the cells which form the myelin sheath around neuronal axons in the peripheral nervous system (PNS) only.

Neurilemma is the collective term used for cytoplasm and nuclei present around the myelin sheath which helps in the regeneration process of nerves.

A Schwann cell surrounds the axon, invaginate it and the plasmalemma of the Schwann cells joins and from a double membrane structure called mesaxon. This mesaxon starts wrapping the axon in spiral fashion and cytoplasm start condensing into the compact myelin sheath.

Chromosome is to Nucleus as DNA is to ?
kakasveta [241]

Chromatin

Chromosome, the highest packing level of DNA, is packed in nucleus. DNA strand itself is packed in chromatin. Chromatin is DNA packaging into 30nm fibers that involve DNA strand with scaffolding around DNA proteins, like histones, in eukaryotic cells’ nucleus.

Explanation:

The DNA strand is folded into nucleosomes, bead-like structures on the DNA and fold up into the 30nm fibers. During meiosis and mitosis, the chromatin is super-coiled up into thicker fibers called chromosomes. Chromosomes within the nucleus can be viewed by a light microscope in a cell in metaphase.
