May be your question is incomplete and please marks me as brainliests...How does water’s molecular structure affect the solubility of substances on Earth? Provide a real-world example.
Answer:
The Anartica iceburgs
The polar covalently bonded water molecules act to exclude nonpolar molecules, causing the fats to clump together. The structure of many molecules can greatly influence their solubility. Sugars, such as glucose, have many hydroxyl (OH) groups, which tend to increase the solubility of the molecule.
The water molecule has an irregular distribution of its electrical charges and it is this irregularity that allows this molecule to be polar and able to solubilize other polar substances.
This can be explained as follows:
The water molecule is formed by two hydrogen atoms and one oxygen atom.These atoms share electrons with each other, forming covalent bonds.The electromagnetic force of the oxygen atom is much greater than the electromagnetic force of the two hydrogen atoms.This causes the hydrogen electrons to be attracted by oxygen, which promotes a displacement of these electrons.This displacement causes the hydrogen electrons to be closer to oxygen than to hydrogen.This creates an irregular electronic distribution in the water molecule, this creates the polarity of the molecule, causing the water to become a polar substance and a dipole.With the irregularity of the electrical charge, water becomes a substance that can form bonds with positive and negatively charged molecules, which guarantees the solubility of a wide range of substances.
Some water-soluble substances are acids, ionic solids, gases, sugars, proteins, salts, among others.

Write down two characteristics of Epthellum tissue . Define meristematics tissue.
Answer:
Polarity
Cellular nature
Explanation:
Polarity: Epithelium is arranged so there is one free surface and one attached surface.
Cellular nature: Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
Meristematic tissues are cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells.

What does the atmosphere contain?
How much nitrogen does the atmosphere contain?
How much oxygen does the atmosphere contain?
What does the atmosphere do?
How many layers does the atmosphere have?
List the layers of the atmosphere and two characteristics of each layer.
Answer:We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Earth's atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
roposphere
The troposphere (between 0 and about 15 kilometers) is the first layer above the Earth’s surface and contains approximately 85 to 90 % of the mass of the Earth’s atmosphere. It is characterized by decreasing temperature with increasing altitude.
The troposphere’s thermal profile is largely the result of the heating of the Earth’s surface by incoming solar radiation. Heat is then transferred up through the troposphere by a combination of convective and turbulent transfer. Weather occurs in the Earth’s troposphere.
Stratosphere
In the stratosphere (between approximately 15 and 50 km) the temperature rises as a function of increasing height.
This warming is the result of the direct absorption of solar radiation by the ozone layer, thereby preventing a large part of harmful ultraviolet radiation from the sun to reach the Earth’s surface.
Mesosphere
The mesosphere is the next layer of the atmosphere (from 50 to 90 km), characterized by temperatures that decrease the further up one goes to an average of -90°C.
A lot of meteors burn up in this layer while entering the Earth’s atmosphere.
Thermosphere
Thereafter the thermosphere takes over where temperatures increases steadily with altitude. It is the layer of the atmosphere which is first exposed to the Sun’s radiation.
The thermosphere also includes the ionosphere, a region of the atmosphere that is filled with charged particles, where especially the auroras occur.
Exosphere
The upper limit of Earth’s atmosphere is the exosphere where the atmosphere merges into space.

Number the steps of Darwin's theory in order.
Answer:
1.Natural Selection
2.Overproduction
3.Variation
4.Struggle for existence
The steps in the theory of Darwin should be performed in the following order: Overproduction, Natural Selection, Variation, and the Fight for Existence.
Thus, the following sequence can be used to number the steps in Darwin's theory, which involves variation where people within a population display innate variances in their attributes. This step is followed by overproduction, when an organism produces more children than the environment can sustain, resource competition results.
People within a population battle for survival because of overproduction and a lack of resources. The last step is natural selection, which involves people having advantageous mutations that suit their environment better have a higher likelihood of surviving and reproducing successfully.
