What is semen?

Semen is a fluid that is ejaculated from the male reproductive system during sexual intercourse or other forms of sexual activity. It is composed of a mixture of fluids, including seminal fluid and spermatozoa (sperm cells).

The seminal fluid, which makes up the majority of semen, is produced by three glands: the seminal vesicles, the prostate gland, and the bulbourethral gland. These glands secrete fluids that provide nutrients and protection for the sperm, as well as a suitable environment for them to survive and function properly.

The seminal fluid contains various substances such as fructose, amino acids, enzymes, and prostaglandins, which help nourish and protect the sperm as they travel through the female reproductive tract.

The spermatozoa are produced in the testes and are responsible for fertilizing the female egg during sexual reproduction. The semen acts as a transport medium for the sperm, enabling them to reach the female reproductive system and potentially fertilize an egg.

Therefore, option c is correct.

Question: Give an example of how energy flows.

Answers

Answer:

Energy flow is the amount of energy that moves through a food chain.

An example

 of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.

Frogs have internal and external structures to help them survive, grow, and reproduce. Name an internal and an external structure, an tell how these structures of the frog survive.

Answers

Answer:

Frogs have some important internal and external structures  that helps them to survive, grow and reproduce. Frog have almost similar internal anatomy to humans.

Frogs have the ability to respire through both lungs and skin. Skin is the external structure that helps them to respire in aquatic ecology.The skins helps to dissolves oxygen from the air and water and releases carbon-dioxide. Skin helps frogs to respire under water but if water do not have enough oxygen, frogs will drown.

An internal structure called liver is present in frog same as human beings. The liver releases chemical called bile that are utilized in digestion of fat and then emptied into the small intestine.

Hence, skin and liver are important for the survival of frog.

The sum of 8 and 5 times a number is 43. Which equation below can be used to find the unknown number?

Answers

Let the unknown number be x
The phrase “8 and” means addition so that’s 8 +
5 times a number is multiplication so that’s 5 times x, or simply, 5x
So the correct equation would be 8 + 5x = 43
And the correct value for variable x is 7
8 + 35 = 43

8+5n=43 is the answer

Give scientists clues about the kind of organisms that lived in an ancient environment

Answers

The answer is a fossil.

The fossil represents a preserved remain of an organism from the past and gives scientists clues about the kind of organisms that lived in an ancient environment.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues
