Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
In water molecules hydrogen bonds provides a special dipole - dipole attraction. Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine). This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge. This makes the molecule of water polar. By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.This property of water is polarity of water.
The property of water that is at work as described in the question is polarity.
Water is composed of oppositely charged ends; a positive end and a negative end. These oppositely charged ends are called "dipoles".
The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.

Describe the end result of mitosis in eukaryotes
Answer:
Two genetically identical diploid daughter cells
Explanation:
Mitosis is the process of cell division through which cells proliferate to create new cells. It allows organisms to grow and replace/repair tissues.
Before the cell divides, the diploid cell (two copies of every chromosome) duplicates its genetic material. During the stages of mitosis, the genetic material is divided between two new cells such that each cell contains a complete copy of the genetic information.
Therefore, at the end of mitosis are two genetically identical daughter cells, each with a diploid genome. Each cell is also identical to the starting cell.
A mutation that causes abnormal cell division can result in
1.) cystic fibrosis.
2.) clogged arteries
3.) sickle cell anerna aneria
4.) skin cancer.
The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.
What can happen if a mutation results in aberrant cell division?Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. A tumour can form as a collection of malignant cells enlarges.
hence, skin cancer
Proteins are made from information found in genes, and proteins regulate a number of vital processes, including cell growth. Protein function can be altered by genetic alterations. Certain kinds of genetic changes to proteins result in healthy cells can become cancer.

when you go into the pool, your skin is like a protective coating. So when you go into a chlorine pool and have a open wound it'll burn your tissue and muscle. because your skin protects you from that.
how does epidermis, dermis, and hypodermis work in this scenario?
I need at least 2 sentences for each.
I'll give a brainest to the first one to answer!
Answer:
The epidermis is the outermost layer of the skin, and protects the body from the environment, As so it did when you wen't into the pool
The dermis is divided into a papillary region and a reticular region. The primary function of the dermis is to cushion the body from stress and strain,
so it helps with the burning.
which functions as a mode of fat storage and provides insulation and cushioning for the integument., which provides coushin.

When viewing a specimen in a microscope, which parts allow you to physically SEE the image?
stage
eyepiece Only
objective only
eyepiece and the objective
Answer:
When viewing a specimen in a microscope, what allows to physically see the image are both lenses, eyepiece and objective.
Explanation:
In optical microscopy, the lenses used to observe microscopic samples play an important role and are necessary for the study of such samples.
- An objective lens is the first to capture the image, providing clarity and proper focus, as well as eliminating color or shape distortions.
- Eyepiece lens obtains the image provided by the objective lens and enlarges it, so that the observer can appreciate the characteristics of the specimen studied.
Regarding other options:
Stage allows to see the prepared sample, ready for its study, but the microscopic characteristics are not appreciated. The eyepiece and objective work together to provide a proper microscopic image.Warm air always wants to _________________.

Answer: A(Rise)
Explanation: Air flows from high pressure, to low pressure. for example: there are 2 rooms, one is cold and is warm that of warm room is thinner air rising towards the ceiling when the air from the two rooms gets mixed. now the cold air will be leaving the room close to the floor. At the same time, warm air from the warm room will rise and move into the cold room close to the ceiling
