Hypothesis: If i add the egg to vinegar then the shell will dissolve within 24 hours

nadezda [96]

Answer :

Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.

Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.

When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.

Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.

Why does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach?

svetoff [14.1K]

In my Biology Honors Class, they taught about gastric juice, or also known as (p H) which is formed by stomach glands, is very acidic and can seriously mess up enzyme trypsin functions. After all, enzymes are a type of catalyst that help break down food, which means that enzymes are a sort of digestive acid as well. Hope this helps!

What three structures, in order, are involved of the production of mature sperm?

34kurt

Answer:

The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.

Explanation:

The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:

Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.

The process of maturation of sperm is of importance for the process of sexual reproduction.
