True or false: Most muscles contain a combination of all three muscle types, slow oxidative, fast oxidative, and fast glycolytic
kkurt [141]

Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.

Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:

  1. Cardiac muscle
  2. Skeletal muscle
  3. Smooth muscle

Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:

  1. Slow oxidative
  2. Fast oxidative
  3. Fast glycolytic.

What evidence does the dische test provide that helps confirm that dna was extracted from the strawberries. Why do you think it
vfiekz [6]

Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.

What does DNA extracted from a strawberry look like?

Observe the line between the strawberry mixture and the alcohol. You will notice a white thread-like cloud appearing at this line. This is strawberry DNA. The DNA will clump together and float to the top of the alcohol layer.

What is unique about strawberry DNA?

Strawberries yield more DNA than any other fruit because they have eight copies of each type of chromosome. The long, thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals.

We intention extract DNA from fruit to investigate how it examines and feels. This procedure is identical to what scientists have to do before they can use the statement contained in this DNA. This announcement can be used to enhance crops so that they are more resistant to infection, insect invasion, or differences in climate.

What male reproductive structure releases sperm into the vas deferens?
lisov135 [29]

The answer is epididymis.

<span>Testicles contain seminiferous tubules, in which sperm is produced, and an epididymis, in which sperm matures. Mature sperm passes through the epididymis to the vas deferens. There, it combines with a liquid secretion from the seminal vesicles and continues through the prostate gland to the urethra. Sperm containing fluid is called semen and it is ejected through the urethra.</span>
