Answer:
Compound X must be an acid
Explanation:
Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.

The spleen and the thymus work together to fight infection. These organs together make up which next level of organization?
Answer:
Tissue
Explanation:
The spleen and the thymus work together to fight infection. These organs together make up immune system.
What is immune system?The immune system defends the organism's body against external invaders. Toxins and germs such as bacteria, viruses, and fungi are examples of these (chemicals made by microbes).
The immune system is made up of various organs, cells, and proteins that collaborate.
The thymus and bone marrow, lymph nodes and vessels, spleen, and skin are all vital to the immune system's proper functioning.
The spleen filters and stores blood, as well as producing white blood cells to fight infection or disease.
The thymus gland is located in the upper chest, beneath the breast bone. It is responsible for the maturation of a specific type of white blood cell that fights off foreign organisms.
Thus, immune system encompasses spleen and thymus.

Answer:
A
Explanation:
Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.
Why water is considered as actual renewable?Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.
Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.
Therefore, Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

Answer: Photosynthesis
Explanation:
Answer:
Explanation:
Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1).
Both plant and animal cells need to produce energy for cellular functions. In both types of cell, this function is carried out by the - O Nucleus O Mitochondria O Chloroplast O Vacuoles
In both plant and animal cells, energy for cellular functions is produced by the mitochondria.

Which best describes the role of chlorophyll in energy conversion?
Answer:
Explanation:
Chlorophyll absorbs light and converts it to chemical energy. ... During photosynthesis, plants absorb light energy from the sun and convert it into chemical energy in the form of glucose.
The role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.
What is Chlorophyll?Chlorophyll may be defined as the type of green-colored pigment which is present in all green plants, some algae, and cyanobacteria. It is present in the chloroplast of the plant and carries out the entire process of photosynthesis.
This green-colored pigment is generally made up of porphyrin rings with magnesium being the co-factor. A chain of carbon and hydrogen is also present. This is known as the Phytol tail. The function of chlorophyll in each photosynthetic organism remains the same throughout.
Therefore, the role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

The difference between solstice and equinox is:
A. During the equinox the solar energy falls on the equator allowing all of Earth to receive equal amount of energy and during the solstice the solar energy falls on the tropics allowing them to receive the largest amount of energy.
B. During the equinox the Earth receives the largest amount of energy in the north pole and not during the solstice.
C. During the solstice the solar energy falls on the equator making all of Earth to receive equal amount of energy and during the equinox the solar energy falls on the tropics making them receive the largest amount of energy.
D. There is no difference they mean the same thing.
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.

All of us live in a neighbourhood or surrounding. We must keep our surroundings neat and clean. This will help us to live a healthy life. Keeping our surroundings clean will only help in the betterment of society. Waste or garbage should not be thrown anywhere, but only in trash bins. Throwing garbage all over the place will dirty our surroundings, pollute the environment. Controlling the use of plastic bags will help to keep our surroundings clean. One should use recycled and eco-friendly products like paper or jute bags instead of others. Littering causes land, air and water pollution. Greener surroundings look beautiful and reduce pollution. Dirtying our surroundings will cause harm to us. So, keep the surroundings clean, live happy and healthy lives.
HOPE IT HELPS YOU .Tobias found a rock that has a mass of 475kg. He placed it in 2000ml of water and the water rose to 2025ml. What is it’s density?
Given parameters:
Mass of rock Tobias found = 475kg
Volume of initial water = 2000mL
New volume = 2025mL
Unknown:
Density = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL
Now let us convert the mass to g;
1000g = 1kg
So; 475kg will be 475000g
So;
Density of stone = [tex]\frac{475000}{25}[/tex] = 19000g/mL or 19000g/cm³

during which phase of the cell cycle does most cell growth occur
Cell growth occurs constantly throughout interphase. S phase is the time when all the cell's chromosomes are replicated so significant cell growth occurs here, but during both G1 and G2 cell growth occurs.
hope this helps
During the interphase of the cell cycle most cell growth takes place.
What is cell cycle?A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the maximum of its time in what is referred to as interphase, where it grows, reproduces its chromosomes, along with prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
The cell cycle's longest phase is interphase. This is the stage at which the cell undergoes and duplicates its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
Thus, the cell growth takes place in the interphase of the cell cycle, and the division takes place in the M-phase.
