What is the density of a liquid that has a volume of 20 ml and a mass of 3g
Answer:
: If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass? m = d×V = 500 mL × 1.11g1mL = 555 g. VOLUME. d = mV. We can rearrange this to .
Explanation:
The density of a liquid that has a volume and mass is calculated first to understand the mass and density of the liquid.
If 500 mL of a liquid has a density of 1.11 g/mL,
what is its mass?[tex]m = d×V = 500 mL × 1.11g1mL = 555 g[/tex]
VOLUME [tex] d = mV[/tex]
The density of a liquid may be a measure of how heavy it's for the quantity measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is denser.
If a liquid that's less dense than water is gently added to the surface of the water, it'll float on the water.
The degree of loudness or the intensity of a sound also : loudnessthe amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters).Therefore, The density of the liquid is 555g.

A species of insect used to be pale green in color. As its environment changed, it evolved to a dark green color that allowed it to blend in better with the plants it feeds on
Which statement best explains how this form of camouflage evolved through natural selection?
A. As the insects consumed the new darker-colored plants, pigmentation from the plants affected their own coloring, altering their genes for color. When they reproduced, they passed the trait for darker coloring on to their offspring. 19. on offse
B. Coloring mutations occurred randomly. Those mutations that were most helpful to the insects survival slowly spread through the population because insects with these mutations were more likely to survive and pass on their genes.
C. The insects were naturally drawn to plants to which their coloring blended. Those individuals with pale green coloring left this environment for an enviroment where they blended better, and individuals with dark green coloring moved in.
D .Abiotic factors in the environment changed, which caused chemical changes that affected the plants' coloring. Over time, the same chemical changes took place in the insects, affecting their coloring in the same way.

The structures of proteins and nucleic acids in living organisms differ in that
A
proteins can take a variety of shapes, and nucleic acids tend to form linear chains
proteins tend to form rings, and nucleic acids tend to form globes
C
proteins tend to form helices, and nucleic acids tend to take irregular shapes.
D
proteins tend to form branched chains, and nucleic acids can take a variety of shapes
Answer:
A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains".

Cloning ________.
Help, is this the answer? assignment 18. question 8. oh my, did I answer this correctly? wink wink please answer if I did, to post this
Answer:
Cloning removes the nucleus from an egg cell and replace it with the nucleus from another organism.
More information :
The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material, which has the same genetic makeup as the original, is referred to as a clone.To make a clone, scientists transfer the DNA from an animal's somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female's uterus to grow.Which of these examples does NOT depend on the population size of organisms living in an area (density-independent)?

Scientists studying the cricket populations on Kauai and Oahu have
also observed that flatwing males wander about more than wild type
male crickets do.
Which hypothesis best explains the observed wandering behavior in
a population consisting mostly of flatwing males?
a Wandering protects flatwing males from the parasitic fly.
b. Wandering helps flatwing males find mates in the absence of chirping
C. Wandering allows flatwing males to access new food sources
d Wandering reduces competition with male crickets that chirp.
Answer:
B/D
Explanation:
it's either B because if a flat Wing male can't find a female that likes is tripping is it helpful to go around and wander and maybe he'll find a mate
or it's D because there's a lot of crickets out in the open and where everybody else is his group gets everywhere so what I'm saying is it help to wander cuz that reduces the competition there so many male chirping that it's kind of hard to find a certain one that will attract the female
The hypothesis that best explains observed wandering behaviour in a population dominated by flatwing males is in the absence of chirping, flatwing males find mates via wandering. So, the correct option is B.
How does this hypothesis make sense?This theory makes sense since flatwing males are unable to generate the characteristic chirping sound which wild-type males make to attract females. As a result, they may need to roam around more to find partners, increasing their chances of reproducing. The other hypotheses do not appear to be as likely to explain the observed behaviour because there is no evidence that travelling is associated with access to new sources of food or protection from competition or parasites.
The hypothesis which most explains observed wandering behavior in a flatwing male-dominated population is Flatwing males find mates by roving in the absence of chirping.
Therefore, the correct option is B.

For hundreds of years one species of moth has always gone back to the same type of tree in the forest to breed. A small portion of that moth population began going to a different type of tree within the same forest to breed instead. What would most likely result from this scenario
Answer:
Evolution.
Explanation:
A small portion of the moth population began going to a different type of tree within the same forest to breed instead of the older one because of the evolution. Due to this evolution, the moth is able to breed on another tree. The characteristics of some moth specie changed over several generations due to may be change in their genetic makeup so we can say that it is because of evolution.
On February 21, a student observes that the Moon cannot be seen in the clear night sky. On what date will the student not be able to see the Moon again in the clear night sky?
The student will not be able to see the Moon again in the clear night sky on the 22 or 23 of March. This is because if February has 29 days, then the moon will not be able to visualize on the 22 of March, and if February has 28 days, then the moon will not be able to visualize on the 23 of March.
What is the phase known when the moon is not visible?The phase when the moon is not visible is known as the new moon. It may be characterized as when the moon is not visible at night in the clear sky, the moon is called the new moon.
This situation arises once a month after 29.5 days. The phase of the new moon happens monthly when we can not able to visualize the moon in the clear sky as well. This happens because of your view location from the earth and the moon orbits the earth.
