Why is it important for gametes to be haploid cells?

Answers

It is important that the chromosomes are haploid, because when the sperm and the egg fuse together the cell will have 46 chromosomes.

The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.

Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.

Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.

Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.

Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Gorge and Hattie want to perform a set of experiments to test the optimal water and sunlight levels of a certain species of pea plant.

Gorge decides to test the amount of water that the species needs to thrive. He takes 24 pea plants and separates them into four equal groups and gives each group a different daily amount of water. He keeps all other environmental conditions the same for each group. He measures the initial height of all the pea plants and then measures their growth after one month.

Gorge averages the data from the individual pea plants and comes up with an average for each group, which he reports in the table below.
After Gorge's experiment is complete, Hattie decides to test the optimal sunlight exposure for this species. She takes 24 pea plants and separates them into four equal groups and exposes each group to a differing daily amount of sunlight. She keeps all other environmental conditions the same for each group, including giving each group 15 mL of water daily. She measures the initial height of all the pea plants and then measures their growth after one month.

Hattie averages the data from the individual pea plants and comes up with an average for each group, which she reports in the table below.
Which of the following conclusions can be made based on the results of these investigations?
A.
This species of pea plant grows best when given 15 mL of water and four hours of sunlight daily.

A. Natural selection resulted in a larger species of chicken.

B. Artificial selection created a larger breed of chicken.

C. Mutations occur less frequently in chickens than they did a century ago.

D. Grocery stores used to sell younger chickens.

Answers

Answer:

B, artificial selection resulted in a larger species of chicken.

Explanation:

People breed the largest animals (in this case chickens) or plants to improve agriculture.

Hope this helps! ;)

The average size of grocery store chicken has more than doubled in the past century because artificial selection created a larger breed of chicken. The right option would be B.

Artificial selection refers to deliberate actions by humans to selectively breed organisms based on desired traits.

Because big size chickens are desirable for their meats, breeders and genetic engineers would select this trait and favors it over other alternate traits using appropriate scientific procedures (such as controlled mating). Thus, chicken with undesirable traits gradually fades off the population while those with desirable traits are made to thrive.

Answers

Answer:

C. a dog buries a bone in the backyard

Explanation:

A dog burying a bone in the backyard is not an observation in terms of scientific methods.

Observation is the process of acquiring data about a phenomenon under study.

Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.

Also, we can use some specialized equipment to make observations.

A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?

Answers

The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.

At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.

Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?

This question is incomplete because the options are missing; here is the missing section:

How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?

by increasing carbon dioxide and decreasing oxygen

by increasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and decreasing oxygen

The answer to this question is by increasing carbon dioxide and decreasing oxygen.

Explanation:

Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.

In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

Describe the relationship between photosynthesis and cellular respiration.

Answers

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.

Answers

Answer:

C.

Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Hope this helps! Have a nice day!

Answer:

C. to produce a new cell

Explanation:

Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

beaked finches died, resulting in an increased average beak depth in the population

How large beak finches survive drough condition?

During drought, finches with larger beaks survive because they were able to crack the hard seeds that were available in the drought situation while on the other hand, the smaller beaked finches died due to unavailability of food which result in an increased average beak length in the population.
