At the end of meiosis ll, each of the haploid sex cells had only half the number of chromosomes as the original diploid cell. Why is this important?

Answers

Answer 1

Answer:

The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.

Answer:

Explanation:

Large shrubs and trees are often planted near rivers to help prevent flooding. The deep, highly-absorbent roots of these shrubs and
trees help soak up heavy rains before they begin to flood the land. Because they reach high above the ground and their branches
and leaves spread outward, trees can also reduce the amount of rainfall that reaches the ground by up to 45%. In the event of a
flood, what additional benefit might these shrubs and trees provide?
They store and hold excess water to prepare for dry seasons:
B)
They prevent flood waters from entering and polluting the rivers.
O
They help to slow down the flow of water, reducing damaging impacts.
D)
They absorb harmful pollutants and stop debris from entering the river.

What resources does your body require to sustain basic levels of nonathletic activity?

Answers

Answer:

Remember: Athletes need more food and fluids than non-athletes. Regular meals and healthy snacks will help fuel your body before and after exercise. It's important to give your body enough of the right fuel in order to feel good and have the energy you need to perform your best.

The human body requires several resources to sustain basic levels of non-athletic activity. These are mentioned below.

What are non-athletic activities?

Non-athletic activities refer to activities that do not involve significant physical exertion or athletic performance. These activities can include a wide range of daily tasks and routines.The important resources are mentioned below:

Energy: The body needs energy to perform all of its functions, including breathing, pumping blood, and maintaining body temperature.

Water: The body is about 60% water, and water is essential for many bodily functions, including regulating body temperature, transporting nutrients and oxygen, and removing waste products.

Oxygen: The body requires oxygen to produce ATP through cellular respiration, which is the process by which cells convert glucose and oxygen into energy.

Macronutrients and Micronutrients: The body requires macronutrients and micronutrients such as carbohydrates, proteins, and fats to provide energy and build and repair tissues.

How does water heat Earth?
O Water traps heat and holds it deep inside the ocean.
O Water transports nutrients and waste.
O Water carries heat from the equator toward the poles.
O Water from rainfall on land starts in the ocean.

Answers

The water traps heat and holds it deep inside the ocean.

Water carries heat from the equator toward the poles. This is one way that water can heat the Earth. This is because the ocean has a significant impact on Earth's climate. The correct option is C.

How does water transfers heat?

Ocean currents transport heat from the tropics toward the poles, and this helps regulate the Earth's temperature. This is why regions near the coast are often more moderate in temperature than regions located inland.

Another way that water can heat the Earth is through the greenhouse effect. Water vapor is a greenhouse gas, which means that it helps trap heat in the Earth's atmosphere. This is important because if the Earth were not warmed by the greenhouse effect, it would be much colder and uninhabitable.

Finally, water also heats the Earth by storing heat deep inside the ocean. This heat can be transported to the surface through ocean currents or released into the atmosphere over time. Overall, water plays a significant role in heating the Earth and regulating its climate.

Therefore, the correct option is C.

Plzzz mark me as brainliest

Answer:

Paranthropus and Giantopithecus are two extinct species that have close evolutionary ties to humans. Paranthropus is an extinct genus of extinct hominin, while Giantopithecus is an extinct genus of ape. Hominins and apes share at least 95% of their DNA with humans, so these two extinct animals probably had some evolutionary ties to humans. Humans walk on two legs and have the ability to speak, whereas both extinct animals walked on four legs. Humans and these extinct animals also share similar body makeup and bone structure. The fossil record of humpback whales is probably incomplete because everything is continuously changing due to evolution.

B. Mismatched mutation
C. Frameshift mutation
D. Genetic mutation

PLEASE HELP ASAP!!!

Answers

Answer:

Three of the most common types of mutations are:

1. POINT MUTATION (one base is substituted for another)

If a point mutation changes the amino acid, it’s called a MISSENSE mutation.

If a point mutation does not change the amino acid, it’s called a SILENT mutation.

If a point mutation changes the amino acid to a “stop,” it’s called a NONSENSE mutation.

2. INSERTION (an extra base, or bases, is inserted)

3. DELETION (a base, or bases, is lost)

Deletion and insertion may cause what’s called a FRAMESHIFT, meaning the reading frame changes.

These are typically one of the most serious types of mutations.

Directions:

1. Following the same procedure you followed during the decoding activity (DNA to mRNA to

Amino Acid), decode the original and mutated sequences and identify them as one of the three

types of mutations listed above. If it is a point mutations, include whether it is a missense, silent,

or nonsense mutations.

The original DNA sequence is:

Why do bacteria need the cell wall ? (select all that apply)
O give them their shape
O gives them their color
O prevents bursting of the cell

Answers

Give them their shape ...........

Answer:

A - it gives them their shape

Explanation:

Bacteria need a cell wall to help maintain their shape

- the cell wall is more stable and sturdy than a cell membrane

The other two answers are incorrect:

- the cell wall has no impact on the color of a bacteria

- the cell wall does not necessarily prevent the cell from bursting as the bacteria is still able to be burst by different cells of the immune system (ex. macrophages)

However! the cell wall does provide some protection to the bacteria as it protects the DNA inside the bacterium from being exposed to harsh environments outside of the cell. but since this isn't an option, A is the correct answer. (but you should probably still be aware of what else the cell wall does)

A. Mass creates a force that can create additional mass

Newton was the scientist that discovered the laws of motions and gravity. Newton’s discovery about gravitational force suggests that the mass creates a force that can create extra mass.

What is Newton's discovery about gravity?

He discovered the gravitational pull and force when the apple from the tree fell on him. According to this, he said that some force makes the things falls towards the planet.

According to his law, the force of the attraction of the object is directly proportional to the mass of the object and inversely proportional to the square of the distance present between the mass of the two objects.

The force is created and influenced by the mass of the object and can result in an increased mass of the object.  It cannot repel objects nor it can generate electricity.

Therefore, option A. mass creates a force that can create additional mass.

how is our understanding of evolution influenced by our knowledge of genetics?

Answers

Answer:

Explanation:

Genetics play a key part in understanding evolution. While two organisms may bear similar or no resemblance whatsoever to each other, their genes can tell us whether or not they were related- and creatures that show change (especially dramatic change) show us evolution through genetics.

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. ... If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
