if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.

There are many different kinds of microscopes. A magnifying glass is a simple microscope. The term microscope commonly refers to a compound microscope. These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters. Sharpening an image under high magnification used the Find adjustment knobs. The part of the microscope that holds the Microscope slide is called the stage.

Fraternal twins, while conceived at the same time, are not genetically identical.
Which statement best explains why these siblings are genetically different from each other
Answer:
Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer:
92 daughter chromosomes.
Explanation:
There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.

Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.

a student is investigating cellular transport. what will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
Cellular transport refers to the flow of substances into or out of the cell across the cell membrane.
When the student places a cell that is 95% water inside of a solution that is 100% water, the cell will achieve net movement and if water continues to enter, it swells up and burst.
When a cell is placed in a hypotonic solution, water flows into the cells and the cell gains volume until it achieves equilibrium. But if water continues to flow in afterwards, it swells up and burst.Learn more about cellular transport: https://brainly.com/question/6949569

Answer:
3
Explanation:
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
