Predict whether each substance will dissolve in water. dissolves in water, does not dissolve in water
Answer: for HCO it dissolves in water
for CH2OH IT dissolves in water
Explanation:
i just took the test
It depends on the particular substance concerned that one can predict whether it will dissolve in water or not. Listed below are some general principles:
Things that usually dissolve in water include:
1. Ionic Compounds: Many salts, including sodium chloride (table salt), dissolve in water because of the attraction between positive and negative ions and polar water molecules.
2. Polar Compounds: Due to the similar polarity of water molecules, substances with polar molecules, such as sugar and ethanol, tend to dissolve in water.
3. Many gases Some gases, such as oxygen (O2) and carbon dioxide (CO2), can partially dissolve in water.
Things that usually don't dissolve in water include:
1. Oils, greases, and hydrocarbons are examples of non-polar substances that do not dissolve in water because water is a polar solvent and does not interact significantly with non-polar substances.
2. Insoluble salts: Some salts, such as lead(II) sulfide (PbS) and silver chloride (AgCl), have low solubility in water.

Answer:
Thylakoids
Explanation:
Thylakoids contain clusters of chlorophyll and proteins known as photosystems. Surrounded by accessory pigments, are essential to the light-dependent reactions. Absorbs sunlight and generate high-energy electrons that are then passes to a series of electron carriers embedded in the thylakoid membrane.
The clusters of chlorophyll and proteins that absorb sunlight and generate high energy electrons in the chloroplast are called photosystem. The correct option is D.
Chloroplasts' thylakoid membrane contains clusters of proteins and chlorophyll known as photosystems. These protein-pigment complexes are essential parts of the photosynthesis' light-dependent processes.
The photosystems' chlorophyll molecules absorb sunlight and use its energy to start a number of electron transfer reactions. The photosystem uses this energy to excite electrons, which are subsequently transported along a chain of electron carriers.
The synthesis of ATP is fueled by these high-energy electrons, which also convert molecules like [tex]NADP^+[/tex] to NADPH, which is necessary for the generation of sugars in the light-independent processes.
The photosystems play a crucial role in converting light energy into chemical energy during photosynthesis. In particular, photosystem II and photosystem I cooperate to efficiently capture and transport solar energy.
Thus, the correct option is D.

Answer:
Energy enters a community when plants and algae trap light energy during photosynthesis. They change the light energy into chemical energy in glucose, which then moves through the community as different organisms eat each other. Some energy is stored through fossilisation, while most of it is lost through heat dissipating into the environment.
Explanation:
Answer:Sample Response
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

Oceans and seas can act as a heat reservoir to regulate climates. They can absorb great quantities of heat in the summer, with very little temperature change. In the winter, oceans and seas release the heat. This is the main reason why coastal climates are milder compared to inland climates. Which choice correctly explains this phenomenon? the high specific heat of water caused by hydrogen bonding the high specific heat of water caused by hydrogen bonding the high freezing point of water caused by the strength of its covalent bonds the high freezing point of water caused by the strength of its covalent bonds the high boiling point of water caused by hydrogen bonding the high boiling point of water caused by hydrogen bonding the high heat of vaporization of water caused by nonpolar bonds
Answer:
The high specific heat of water caused by hydrogen bonding
Explanation:
Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).
Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385 Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.

Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.
Explanation:
The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.
The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.
MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.
The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.
The cellular process that enables cells to grow and develop into tissues is mitosis.
Mitosis allows a single cell to divide and form two morphologically and genetically identical cells. The two cells each also have the potential to divide if the conditions are right.
Thus, a single cell has the capacity to become tens, hundreds, or even thousands of cells as a result of mitotic division.
A tissue is formed from a group of cells that have differentiated to perform similar functions. In order words, without mitosis, there is absolutely no chance for tissues to be formed.

Scientists investigated two types of violet plants. One was found more frequently in shade, the shade violet. The other was found more frequently in sunny places, the violet. Which violet is which? Give a reason for your choice.
Answer:
Violet plant with small leaves found in sunny places while violet plant with big leaves are found in the shade.
Explanation:
In our planet, the plants though they cannot move like animals and humans, they can adapt themselves to the surroundings and the environment. Plants have the ability to adjust themselves in the varied climate and landscape around themselves.
Almost all the plants need sun light or sun energy to grow and make their own food. Some plants grow well in direct sun light while some others grow in shades.
In the context, scientist discovered two varieties of violet plants out of which one grows frequently in the sunny places whereas the other found frequently in the shade.
Now the violet plant which have small leaves than the other violet plant are found more frequently in the sunny places as these plants get direct sun light or energy all through the day to make their food. While the plant which have adapted to make food in the shade having large leafs so they can absorb more of sun's energy and make their food. They are found in the shade.

To reproduce, female elephants produce eggs and male elephants produce sperm. Offspring are produced by the fusion of an egg with a sperm cell. Which statement is true about the offspring? A. The offspring are genetically distinct from the parents because the egg and sperm are both diploid. B. The offspring are genetically identical to the parents because they are produced by sexual reproduction. C. The offspring are genetically distinct from the parents because they are produced by sexual reproduction. D. The offspring are genetically identical to the parents because the egg and sperm are both diploid.
Answer:
B
Explanation:
C, The offspring are genetically distinct from the parents because they are produced by sexual reproduction.
Sexual reproduction is the fusion between an egg and a sperm cell, and each of these cells has a single set of chromosomes, a haploid. Because of this, their offspring will be a diploid organism with half of its genetic information from their mother and half from their father. The offspring's genetics will be thus unique compared to their parents', because it is a combination of both of their genetic info. If they were to be identical, we would be looking at asexual reproduction, not sexual.
