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.

what do you think is a way for geologist to locate ore bodies? justify your answer
From my research, there is lots of information on how to extract ore, but I can't find any information on how these ore deposits are found in the first place, apart from 'looking for surface formations'. So, what kind of formations would exist for different types of ore? Are there any other ways of finding ore?

You are unable to lift an object. Which property makes the object difficult to lift?
A. density
B. mass
C. volume
D.weight
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.

Why is it important for gametes to be haploid cells?
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.

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.
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.

What are the disadvantages of polygamous in animals
Answer:
The principal disadvantage of monogamy is a lack of variety. Monogamy has the potential to lead to routine, and possibly boredom.

Which of the following would not be considered an observation in terms of the scientific method? A. tasting a pasta sauce after adding a new ingredient B. looking at a blood sample through a microscope C. a dog buries a bone in the backyard D.listening to bats of different materials hitting a baseball
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.What is located outside of the center of the atom?

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.

The nucleus is surrounded by a membrane. This membrane has pores that enable the nucleus to carry out one of its functions. What do these pores allow to happen?
A) nutrients that are stored in the nucleus to enter the cytoplasm
B) proteins that are made in the nucleus to pass into the cytoplasm
C) waste substances to enter the nucleus
D) genetic information to pass from the nucleus to the cytoplasm
Answer:
D
Explanation:
The nucleus contains the genetic information of the cell. When the cell needs instruction to make protiens, Rna carries those instructions out of the cell because DNA is too large to fit through the pores. Proteins are made in the ribosomes.
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?
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.
