When we look at the food web our job is to take away the flies because of the insecticide sprayed. When we do that we see that sparrows don’t have any food. They sparrows will start dying off because of that and the snakes and the sparrow hawks eat the sparrows. This will cause the sparrow hawks to die if quicker than the snakes because the snakes still eat the mice. The mice population will slowly drop because they also ate the flies. The caterpillar population will increase because there are no sparrows to eat them.

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. Why would these be helpful in the the treatment of tumors?
Answer:
This would be helpful because mitosis is the way something grows. Cells split apart and what they're inside grows bigger. So if a tumor undergoes mitosis, then it grows. That is bad.

Based on the blast results, what can you conclude about your query sequence? answer the questions below by dragging one pink label to each pink target and one white label to the white target. Pink labels may be used once, more than once, or not at all.
The BLAST program (Basic Local Alignment Search Tool) was developed to perform searches and compare biological sequences against a database that contains a large amount of information.
The BLAST programThe BLAST program performs the search using segments of the query sequence against the database sequences. The query string is divided into small words (word) that will be used in the search. These substrings are compared with the subject strings until identical strings are found.
With this information, we can conclude that the BLAST program was developed to perform searches and compare biological sequences.

Two species regularly come into contact and form hybrids that have higher fitness than either of the parental species. What are some likely consequences of regular hybridization between these species
Answer:
hybridization is categorized as crossing organisms that have different traits to bring together the best of each. However, this can come with some post-zygotic barriers.
Reduced hybrid viability: hybrid offspring does not survive
Reduced hybrid fertility: hybrid offspring cannot reproduce
hybrid breakdown: first generation of hybrids are viable and fertile, however, their offspring (generation 3) are sterile.

How can farmers personally test their pigs' DNA?
Answer:
using pig hair
Explanation:
because they take the pig hair off
DNA test is a genetic test. It identifies the genes, chromosomes in an individual. Farmers can use any cell of the pig to test the genetic content of an individual.
What is DNA test?A DNA test is a medical test which can identify the mutations present in the genes, chromosomes or proteins. These mutations can indicate if an organism has a genetic condition. DNA tests can help in identifying the risk for developing a certain condition or passing on a genetic disorder.
Farmers can contact the nearest DNA companies or forensic laboratories in their area and usually the companies send a sample DNA kit for the farmers to collect sample themselves and then send them back to the laboratory or company for further analysis.

Question 4
Which of your fossils are most likely heterotrophs? Which of them are autotrophs? How do you know?
Answer:
Fossil A: Heterotrophs
Fossil B: Autotrophs
Fossil C: Heterotrophs
Fossil D: Heterotrophs
Explanation:
I'm not 100% sure of the answer but I'll explain:
Fossil A is a heterotroph because it looks like a snail shell and snails eat other things for energy (keep in mind heterotrophs eat other things for energy while autotrophs make their own energy through the sun)
Fossil B is an autotroph because it looks like a fern which is a plant and plants use the sun for energy
Fossil C is a heterotroph because it looks like a centipede or some arthropod which eat other things for energy
Fossil D looks like a brachiopod which eats other things for energy
(If you want to fact check me you can search each of the organisms and how they get energy)
