Why does ice have the lowest density?

Answers

Answer 1

Answer:

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

The answer would be d

The appropriate response will be Option D (weight).

The weight of such a specific individual or object, defined as kilograms or milligrams as well as tons, seems to be how hefty something is.

The other given options such as:

Density - This notion is essential because it enables us to discern which compounds swim and which components or materials sink in what seems like a liquid.Mass - A dimensional total quantity that represents the material's quantity of substance.Volume - The storage space that a particular material occupies whereas the mass would be the quantity it holds.

Such given choices aren't connected to the given scenario. Thus the above is the perfect answer.

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.

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.

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.

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.

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?

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.
