Can you forecast an earthquake? Explain why or why not.
Answer:No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

What are Vegetables?Vegetables are defined as those parts of plants that are consumed as food by humans or other animals where the original meaning is still commonly used and includes all edible plant parts including flowers, fruits, stems, leaves, roots, seeds in the case applied to plants collectively.
There are several types of vegetables which are as follows:
Leafy green – lettuce, spinach and silverbeet.Cruciferous – cabbage, cauliflower, Brussels sprouts and broccoli.Marrow – pumpkin, cucumber and zucchini.Root – potato, sweet potato and yam.Edible plant stem – celery and asparagus.Allium – onion, garlic and shallot.The carrot is the type of root vegetable which is typically orange in color, though purple, black, red, white, and yellow cultivars exist.

What are the new cells called and how do they compare with each other?
Answer:
The original cell is called the mother cell and the two new cells are called daughter cells.
Explanation:
The mitotic (M) phase and cytokinesis (C phase) together are called cell division, the division of the parent cell (original) into two daughter cells (new cells), each with the same genetic information (chromosomes) as the parent cell. Mitosis does NOT occur in prokaryotic cells that do NOT have a nucleus. (tesd. net)
The nucleus divides during mitosis, while the cytoplasm divides during cytokinesis. The two new cells are referred to as daughter cells.
What is daughter cells?Diploid cells are the daughter cells of mitosis. Diploid cells have two complete chromosome sets. Mitosis creates no genetic diversity in normal healthy cells because the daughter cells have exact copies of their parent cell's DNA. Either of the two cells formed when a cell divides through mitosis. Because they have the same number and type of chromosomes as the parent cell, daughter cells are genetically identical. Daughter cells are formed by the division of a single parent cell. They are produced by the mitotic and meiotic division processes. Cell division is the reproductive mechanism that allows living organisms to grow, develop, and reproduce.To learn more about daughter cells, refer to:

Please correct me if I am wrong for the third one
Answer:
1. Hypotonic
2.Isotonic
3.Hypertonic
Explanation:
Number 1 is hypo tonic because solute is going into the cell. The cell is getting bigger and expanding. You can think of Hypotonic as getting bigger by using Hypo which can be Hippo. Hippos grow bigger over time.
Number 2 is Isotonic. The water is going in and out at the same rate. Therefore, nothing really changes here.
Number 3 is Hypertonic because the cell has shrunk.

What is one reason that a food web might be a better description of an ecosystem than a food chain?
O No animals are chained.
O Animals have only one option of what to eat.
O Organisms have a choice of what to eat,
At least one animal in the web has webbed feet.
One reason for which a food web might be a better description of an ecosystem than a food chain is that the organisms have a choice of what to eat. Thus, the correct option is C.
What is a Food web?A food web is the representation which consists of all the food chains in a single ecosystem. Each living thing in an ecosystem has the part of multiple food chains. Each food chain in the ecosystem is one possible path which the energy and nutrients may take as they move through the different ecosystems.
The food web shows more of the interactions which are present between organisms of the ecosystem and the trophic levels which are included from the different trophic levels such as producers to consumers to decomposers. In a food web, an organism have a choice of what to eat.
Therefore, the correct option is C.

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.
A Punnett square is shown. The columns are labeled Upper F and f. The rows are labeled Upper F and f. Clockwise from upper left the boxes contain: Upper F Upper F, Upper F f, Upper F f, f f.
Based on the Punnett square, what is the probability that the offspring will have freckles?
25 percent
50 percent
75 percent
100 percent
Answer: a. 25 percent
Explanation:
In the Punnett square below what would be the genotype for the organism represented by box 2?
1.) bbss
2.) BbSs
3.) bbSs
4.)Bbss
Answer:
bbss
Explanation:
mitochondria is the powerhouse of a cell
The genotype for the organism is represented by box 2 - 1.) bbss.
Punnett square is a way to find the genotype of any trait either monohybrid or more than one allele. To predict the outcome of breeding experiments where one trait with two boxes and two traits are being followed and the Punnett square is larger, with sixteen boxes.
Each side has gametes, representing alleles they have, produced by each parent.Each box shows the zygote that has a genotype combination of the gametes.for instance, here bs is fused with bs which form the zygote that contains the genotype bsbs.Thus, The genotype for the organism is represented by box 2 - 1.) bbss.

how does cancer develop?
Answer:
Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.
