Answer:
1/2
Explanation:
Well it's like you get 23 chromosomes from each parent. 23 from your dad, and 23 from your mom. In total that's 48 chromosomes, which 23 pairs of chromosmes. Have you ever seen those DNA testing kit commercials for "23 and me" yeah that's based off of the fact that every body has 23 chromosomes. Anyways the main thing is that each parent contributes 1/2 of genes to the offspring.
Which process is defined as breaking down rocks into smaller pieces without changing the rocks' compositions?
erosion
oxidation
chemical weathering
mechanical weathering
Answer: Mechanical weathering
Explanation: Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Breaking down rocks into smaller pieces without changing the rocks' compositions is called mechanical weathering.
A rock refers to a solid mass which may be found above or below the ground. Rocks are the source of soil. Soil is formed when a rock is broken down. The process of break down of a rock is called weathering of rock.

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.
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.

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.

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.
