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 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.

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.
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.

In the picture, there is a dark moth and light moth on each tree. If all the trees are dark colored
(without lichens) like the tree on the right, which moth is more likely to survive? DS
(1 Point)
Answer:
If all the trees are dark-colored (without lichens) like the tree on the right, the moth that would most likely survive longest is the dark-colored moth.
Explanation:
This is because of natural selection (which means "A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.") The dark-colored moth is best adapted to its surroundings compared to the light-colored moth, and it will survive the longest (of the two) according to this definition of natural selection.
Hope this helps :)
