Approximately two-thirds of the mass of a cell is water, and the water is important to maintain the cell's integrity. What would happen to a plant cell during a period of severe drought?
Answer: The plant cell would die
Explanation:
Water is one of the important component in the body of the living organism. It is used to maintain the integrity of the cell.
The cytoplasm in the cell is completely made of water and it helps in the various metabolic activities that takes place inside the cell.
The water inside cell helps in providing mobility to the cell. In the period of severe drought, the cells integrity will be disturbed and the cell would die deprived of water.

What structure contains the embryo of a plant?
The structure that contains an embryo is present between the endosperm and fruit wall. The structure is called the seed.
What is an embryo?The embryo is the undeveloped offspring indie the womb or the plants inside the seed. In plants, it is the undeveloped plant inside the seed. Each seed contains an embryo.
Each ovule turns into a seed when fertilization takes place. Each seed has an embryo, which is a tiny, developing plant. When the sperm cell fuse with the egg, it forms an embryo. The seed is present between the endosperm and the fruit wall.
The seed is the hard part of the plant. It is preset inside the soil to form offspring.
Thus, between the endosperm and fruit wall is the structure that houses an embryo. The form is referred to as the seed.

Which description is not a property of a base?
A.) pH lower than 7
B.) Turns litmus paper blue
C.) Bitter taste
D.) Slimy feel
The right option is; A.) pH lower than 7
pH lower than 7, is the description that is not a property of a base.
A base is any solution that has a pH higher than 7. Bases can either be strong (such as lye, ammonia, bleach), or weak (such as baking soda, and toothpaste). The strong bases can be harmful to organisms and can destroy substances. Bases usually have a bitter taste, and a slimy feel (such as in soap). Bases produce a salt and water when they react with water. Also, they change the color of indicators (turns litmus paper to blue, and turns phenolphthalein to pink).
Answer:
the answer is A

What is the the result of mixing a water molecule and an oxygen molecule together?
A.they are not attracted to each other because one is polar and one is no polar.
B. They are attracted to each other because they are both polar.
C. They are not attracted to each other because water contains an ion bond.
D. They are attracted to each other because they are both nonpolar.
Final answer:
Water is a polar molecule with a bent shape that leads to partial charges, while an oxygen molecule is nonpolar. Water and oxygen do not attract each other based on polarity. So the correct option is A.
Explanation:
The result of mixing a water molecule and an oxygen molecule can be assessed by understanding the polarity of each molecule. Water is a polar molecule due to its bent shape and the difference in electronegativity between the hydrogen and oxygen atoms, leading to partial positive and negative charges at different parts of the molecule. Since the oxygen molecule (O₂) is nonpolar and does not have a separation of charge, water and oxygen are not attracted to one another based on polarity.
Therefore, the correct answer is A. They are not attracted to each other because one is polar and one is nonpolar.

Long chains of sugars are ______. Name three
The long chains of sugars are glucose, sucrose, and fructose. These chains are significantly made up of glycosidic bonds. The molecules of glucose construct glycosidic bonds with their own, fructose, and galactose.
What is the long chain called?When numerous molecules of glucose are correspondingly linked together in a long chain, these molecules formed a structure that is known as polysaccharides (many sugars). The link formed between each molecule is known as a glycosidic bond.
The structure of glycogen, galactose, and other components are the long chains of sugar called polysaccharides. They are generally made up of repeating units of single sugar molecules called monosaccharides.
Therefore, the long chains of sugars are glucose, sucrose, and fructose. These chains are significantly made up of glycosidic bonds.

the bubbles of gas are only produced while photosynthesis is taking place.
What Two measurements would the student make to calculate the rate of photosynthesis?
The two measurements taken here are the size of the bubbles and their rate of production.
What is photosynthesis?Green plants and certain other creatures convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to change the water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
It is hard to overstate the role that photosynthesis plays in sustaining life on Earth. There might eventually be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. Only chemosynthetic bacteria, which can use the chemical energy of certain inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.
The fossil fuels (coal, oil, and gas) that drive modern society today were created by plants using energy from photosynthesis carried out millions of years ago. Green plants and tiny critters that fed on plants grew more rapidly in the past than they were eaten, and as a result, sedimentation and other geological processes buried their remnants in the Earth's crust. These organic residues were gradually transformed into fossil fuels there, shielded from oxidation.
Therefore, the two measurements taken here are the size of the bubbles and their rate of production.

Eukaryotic plant cells store and remove waste materials by:
Using the cell membrane to send them out through the vacuolesA plant cell that is eukaryotic is one which has a nuclei and contains genetic information.
A eukaryotic plant cell is one that like an animal cell builds up waste materials and it has a special way of disposing of waste through its vacuole where waste products are stored and eventually removed.
As a result of this, we can say that a eukaryotic plant cell stores and removes its waste products from the vacuole, using the cell membrane.

Why is carbon so abundant in living things when oxygen is the most abundant element on Earth?
Answer:
Although oxygen constitutes 21% of the total atmospheric gases utilized by the organisms but carbon is the abundant element of the living organisms.
This happens because a living organism is composed of the smallest structural and functional unit called cell which is formed by the aggregation of the small molecule mostly which contains the carbon.
This is due to the reasons as the carbon element shows two properties called catenation sue to which carbon can form long chains by attaching the same carbon element and tetra-valency where the carbon can attach four different elements.
Thus, carbon is the abundant element of the living organism.
