Describe a sperm cell. How does each structure contribute to the sperm's function? please this should be at least 150 words, I will be MARKING as BRIANILIST , please don't copy from Google, thank you so much.
Answer:
A sperm is a gamete male or a sex cell. It joins with the female gamete, called an ovule, to create a zygote. The process of formation is called fertilization.There are two parts to the sperm cell, the head and the tail. The arrangement of the sperm makes it ideally built for the efficiency of its purpose. The tail of the sperm helps give it the momentum it needs to reach the egg cell, so that the embryo can be created first. The sperm develops a tail and sheds the excess cytoplasm of the shaft. When the sperm is full, the tail will spin like a propeller such that the sperm will move itself forward. Mitochondria in the linking component generates the energy ( ATP) required to travel.The sperm cell is made up of the head, body (mid-section) and tail. Each of these parts is equipped with different molecules and a smaller structure that enables the sperm to function properly as a whole. Mature sperm cell (sperm cells) is 0.05 milliliters wide. It's made up of the head, body and tail. The head is covered by the ac-cap and contains a dense genetic material nucleus of the 23 chromosomes.
hope this helped!
Answer:
A sperm cell is the male reproductive sex cell. Sperm cells of different animal species have different shapes and structures. In humans it consists of two major parts, the head and the tail. The head is flat and almond-shaped. The head contains the nucleus which carries genetic substances called chromosomes. One sperm cell contains half the number of chromosomes the species has. Humans have 46 chromosomes so each sperm cell has 23. The sperm cells also carry the X or Y chromosome that determines the sex of the future child.
The tail of the sperm, sometimes called the flagellum, is a slender, hairlike bundle of filaments that connects to the head. It whips and undulates so that the cell can travel to the egg. Following sperm deposition in the female reproductive tract, activation of tail movement is suppressed until the sperm is carried to within a relatively short distance of the egg. This gives the sperm an increased chance of reaching the egg before exhausting its energy supplies.

Explanation:
The updrafts and downdrafts represented within this cloud are primarily caused by differences in?
A.altitude above sea level
B.air density
C.relative humidity
D.specific heat
Answer:
B.air density
Explanation:
Updraft and downdraft is the upward and downward movement of air.
It caused by differences in air densities. There could be differences in air current due to the heat that occur in the ground during the day time which makes air above more warmer than the air below. The air above is less dense as it rises above it becomes cool.
It also occur when air current moves over mountains.
How do barnacles get nutrients?
O They catch small land insects.
O They attach themselves to seaweed and feed on it.
O They filter microscopic organisms from the waters.
O They crawl upon the ocean floor and feed on parasites.
Answer:
The answer is: They filter microscopic organisms from the waters.
Explanation:
Barnacles are filter feeders, which is why they are usually on dock poles and non-moving structures underwater. They do not need to travel to get food, because it comes to them!
Answer:
The answer would be that they filter microscopic organisms from the waters .
How traumatic is this data collection for the animals that are caught and brought on the research boat
Answer:
Capture myopathy
Explanation:
It should be understood that any animals that is captured and placed on a boat for research, might be needed to be tied to avoid it from trying to escape, which might cause the boat to capside.
In this case, the animal may experience a situation known as a capture myopathy. This is a kind of muscle meltdown, and if care is not taken, the animal might eventually become paralysed.
What would happen during DNA replication if DNA polymerase was not functional? (2 points) Free nucleotides would not bind to the parent strands. DNA would continually replicate in an unregulated manner. The newly synthesized strand would still contain primers. The parent DNA molecule would not be split to form two stands.
Answer:
If DNA polymerase were not functional, then the nucleotides wouldn't assemble to replicate another strand of DNA

Do living organisms depend on each to survive?Why or why not
Answer:
Yes (very true)
Explanation:
All living organisms depend on each other to survive, whether be a small bacteria or something as large as blue whales. Living organisms depend on each other and on their environments, or habitats, to meet their needs for survival. For example there's this concept called symbiosis, which explains the relationship between two organisms or more where both benefit most of the time from the association. For example, some plants and fungi have symbiotic relationship where plants provide food for fungi (such as carbohydrates) and in return, fungi colonize the roots of plants and provide extra absorption of nutrient and water.

Do frameshift mutations involve a substitution or a deletion? Select the correct answer
Answer: deletion
Explanation: A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases.
what causes rain to fall from the sky
Answer:
Rain is precipitation.
here’s the cycle:
1. Evaporation.
A body of water is evaporated by the heat of the sun. The water particles turn into vapor gas and move up as they are evaporated, and this leads to the next step.
2. Condensation.
The particles/molecules are collected inside of the clouds. They continue to collect until they’re ready for the next step.
3. Precipitation.
The droplets are now large enough to form rain, so they fall out from the clouds. This is precipitation.
And the cycle continues.
So that’s how rain is formed.

Since the beginning of the Industrial Revolution, how much has the pH dropped in the oceans? 0.9 0.7 0.1 0.3
Answer:
0.1
Explanation:
pH of ocean has decreased from 8.2 to 8.1, it means by 0.1, which refers that slowly ocean water is moving towards getting acidic and that will be very harmful for marine life and human population as well.
Industrial revolution is one of the main cause of decreasing pH in oceans as it leads to pollution, combustion of fossil fuels and global warming which releases more amount of CO2. Most of this CO2 dissolves into seawater, mix with H2O and form carbonic acid (H2CO3), which is acidic in nature.
Hence, the pH is dropped in the oceans by 0.1.
