When ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).
What is Density?
Density is defined as the mass per unit volume of a substance and is denoted by ρ, although the Latin letter D may also be used.
Density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where ρ is density, m is mass, and V is volume. It has the units of mass divided by volume such as grams per centimeters cube [tex](g/cm^3)[/tex] or kilograms per liter (kg/l).
When water changes from a liquid to a solid state that is liquid in the form of ice, its density will increase as it becomes saltier and colder.
Thus, when ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

2. If the climate were to change in an environment,
it is more likely that some individuals within a
population will survive if
a. the individuals stop reproducing.
b. the individuals are genetically
identical.
c. there is genetic variation within the
population
d. the individuals reproduce asexually.
Answer:
C, there is genetic variation within the population
Explanation:
When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population. So, the correct option is C.
What is Genetic variation?Genetic variation is defined as the difference in DNA between individuals or between populations where there are many sources of genetic variation including mutation and genetic recombination. Mutations are the ultimate source of genetic variation, but some other mechanisms, such as genetic drift, contribute to it as well.
Genetic variation is caused by mutations that can create completely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis. When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population.
Therefore, the correct option is C.

1. This organelle exists in two forms: Rough and smooth and acts as the transport system for the
cell.*
What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

Write a research paper about do you believe in evolution? Why or why not?
Answer: Yes
Explanation: Evolution is a fact, but not all evolve at the same time, not all have the equality of the study and for this reason evolution is delayed worldwide.
Answer:
Yes, I belive in evolution because of how muech the world has changed it's form over they years. To break it down a little more take humans for an example we weren't always like this we didn't have all these citys, buildings, tec, and so on. Back in the days when we still have native tribes and explorers they didn't have a house to sleep in they slept in tents or in carrages but as time evolved so did our minds and our brains thats when cabins started then after that houses then cars, power, and even more, but they had to learn how to do this. They evolved their minds to create they evolved to make it throught bad times they had to evolve along with mother nature her self. we all made it this far thanks to the great mind of evolution adn thats why I believe.

Q: Which image shows the most likely path of a barrel floating down a meandering river?
Answer:
C
Explanation:
A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.'
Image C is the most likely path of a barrel floating down a meandering river.
What is the meandering of a river?A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.' The outer edge of the water moves faster than the inner as it flows around these curves.Meanders form as a result of both deposition and erosion, and they gradually migrate downstream. Because of the decreased friction, the force of the water erodes and undercuts the river bank on the outside of the bend, where the water flow has the most energy.To learn more about : Meanders

How do owls relate to biotechnology?
Answer:
Owls hunt throughout the night in deserted places such as cemeteries, run-down farms, and other open areas. The diet of many owls consists mainly of rodents and other small animals. Prey is usually eaten whole, but the whole prey is not digested. An owl's digestive tract compresses the undigested portions of the prey, such as fur and bone, into a compact pellet that the owl coughs up and expels through its mouth.Explanation:

A wildfire in a forest causes a population of deer to flee to a nearby field. This field is home to a population of rabbits. Which is an effect
of the deer moving to the field?
Answer:
C
Explanation:
They both eat the same thing which is plants this will either cause one of the species to flee to new land with plants or a fight among them for survival
Answer:
Overabundant deer can spell trouble for people, including frequent car collisions and the spread of zoonotic diseases. But deer can also disrupt wildlife communities -- such as forest songbirds -- by eating away their habitat. In a new study, researchers show that areas in the eastern US with high deer numbers tend to have fewer birds that need forest shrubs.

What are the differences between three types of inertia?
Answer:
Explanation:
Inertia of rest - An object stays where it is placed, and it will stay there until you or something else moves it. ( Dust particles stay at rest until you shake a carpet.)
Inertia of motion - An object will continue at the same speed until a force acts on it. ( Body going forward when a car stops.)
Inertia of direction - An object will stay moving in the same direction unless a force acts on it. ( One's body movement to the side when a car makes a sharp turn.)

Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
Answer:
When the liver has broken down due to harmful substances, its by-products are exerted into the bile or blood. Bile by-products enter the intestines and leave your body in the form of feces. Blood by-products are filtered out through the kidneys and leave the body in the form of urine.
Explanation:
When the liver is damaged by harmful substances, their by-products move into the bile or blood, where the by-products of bile enter the intestines and leave your body as feces and by-products of the blood. -products are filtered through the Kidneys and leave the body as urine.
What is Excretion?Excretion is defined as the process in which metabolic waste is eliminated from an organism, this is done by the lungs, kidneys and skin in vertebrates.
This is in contrast to secretion, where matter may have specific functions after leaving the cell where excretion is an essential process in all forms of life.
Through excretion organisms control osmotic pressure which is defined as the the balance between inorganic ions and water and maintain acid-base balance.
Thus, when the liver is damaged by harmful substances, their by-products move into the bile or blood.
