Which best describes the effect on another population in the food web below if nearly all of the field mice are removed?
grass
black-footed
ferrets
field mice
seeds
lynx
The number of lynx will increase.
The amount of grass will decrease.
The amount of seeds will increase.
The number of ferrets will decrease.
Answer:
The number of ferrets will decrease.
Explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In each community, organisms maintain specific relationships among each other; these can be depicted within a food web.
Black-footed ferrets are typically found within prairies, and consume other small animals such as rodents. The removal of mice reduces their food supply, limiting their chance for survival. Thus, the ferret population would decrease due to migration, or death.
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited. A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time. Assuming that both parents are heterozygous for the gene that causes the disease? Assume that both parents are heterozygous for the gene that causes the disease. Enter your answer as a fraction - e.g. 1/2 - and do not put anything else in the box.
Complete question:
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.
A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.
Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).
Answer:
The probability that the second child will also have the disease is 1/16.
Explanation:
Available data:
Two genes independently inherited: one for blood type, the other for diseaseMan with type A blood x Woman with type B blood Both parents are heterozygous for the gene that causes the disease; DdIf the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.

An IV drip delivers 5mL/hour to the patient. How many liters of the drug will you need to administer this drip for 24 hours?
Answer:
.12 liters
Explanation:
if it give 5ml an hour, it would give 120ml in 24 hours which is only equal to .12 liters.
The amount of drug which we need to administer this drip for the period of 24 hours is 0.120L or 120mL.
What is IV drip?Intravenous (IV) therapy is a medical technique which involves the administration of fluids, medications, and nutrients directly into a person's vein.
IV fluids are the specially formulated liquids which are injected into a vein to prevent or treat dehydration in the patients. IV fluids are used in people of all age groups who are sick, injured, dehydrated from exercise or heat, or undergoing surgery.
IV drip in 1 hour = 5ml or 5/1000L or 0.005L
Therefore, the IV drip in 24 hours = 5mL × 24
IV drip in 24 hours = 120mL or 0.120L
Therefore, the IV drip volume in 24 hours is 0.120L.

Explanation:
How many of each molecule do you think will be produce by this reaction: five O2 molecules and nine H2 molecules
Explanation:
But two water molecules contain four hydrogen atoms, which means that two hydrogen molecules must be present on the reactant side of the equation for the numbers of H atoms to balance (Figure 7.2 on the previous page).
Which of the following best explains how viruses cause disease?
A. The virus particles ingest cells in order to disrupt their processes. Ingesting cells allows viruses to
continue to replicate.
B. The virus particles digest parts of the host cell mechanism to create more viruses. The cell is left
without means to replicate.
C. The virus particles infect host cells and use the host cell's machinery to create more viruses. This
disrupts the host cell's processes.
D. The virus particles invade
host cells and use the host cell's machinery to create many more host
cells. This causes overproduction of cells.

Why does Osmosis affect plant and animal cells differently?
A. Animal cells have a cell wall, leading them to burst instead of stretch.
B. Plant cells have a cell wall, so they become turgid, or swollen, instead of bursting.
C. Plant cells have chloroplasts, which use sunlight to control the water flow.
D. Animal cells do not have a cell wall because they need to use Osmosis, whereas plant cells do not use Osmosis so they have cell walls to prevent the movement of water.
Osmosis affects plants and animal cells differently because plant cells have a cell wall, so they become turgid, or swollen, instead of bursting. The correct option is B.
What is osmosis?Osmosis is the diffusion of particles from a low concentration region to a high concentration region. It is the movement of solvent particles through a semi-permeable membrane.
Animal cells do not have a cell wall, and plant cells contain a cell wall. Plant cells contain a vacuole and animal cells do not. These are the difference between these cells.
The process of osmosis act differently on plant cell and animal cell. The animal's cell will burst quickly in a concentration, and the plant cell will not burst out because it contains a cell wall.
Thus, the correct option is B. Plant cells have a cell wall, so they become turgid, or swollen, instead of bursting.

What are the 4 nitrogenous bases found in DNA and what are their appropriate pairings?
Answer:
DNA has four nucleobases: adenine, thymine, guanine, and cytosine. The nucleobases in a DNA strand have preferred partners to form hydrogen bonds with. Cytosine pairs with guanine, and adenine pairs with thymine. These are the base pairing rules that allow DNA replication and protein synthesis to happen.

By definition, a compound microscope possesses:
O ionic bonds connecting oppositely charged ions
O two sets of magnifying lenses
O the ability to produce beams of electrons
a single objective lens
all of these answers are correct
Answer:
two sets of magnifying lenses
Explanation:
This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the
two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.
