Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.

A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.

Which statement correctly compares mass and weight?
A.Both depend on the force of gravity pulling on an object B.The basic unit of both is the kilogram C.Both mass and weight ofan object would be less on the moon than on Earth D.Weight varies with location, but mass does not vary
Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
[tex] Weight = mg [/tex]
Where;
m is the mass of the object.g is the acceleration due to gravity.Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.
The sun is a natural resource used by people. Why is the sun considered a renewable resource? *
the sun goes away at night and then comes back in the morning
on cloudy days, the sun cannot be used
solar energy from the sun is limited
the sun is an unlimited source of energy that isn't used up as fast as people use it
Answer:
Because the earth continuously receives solar energy from the sun, it is considered a renewable resource.

Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food
Answer:
D. Increased availability of food
Explanation:
Trust
The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.
Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.
Thus, the correct option is D.

Calculate: Punnett squares can be used to predict probable outcomes of genetic crosses. To calculate probability, divide the number of one kind of possible outcome by the total number of all possible outcomes.
