How does a chemical equation with coefficients relate to the law of conservation of mass?
A.The total mass must remain constant in a chemical reaction with coefficients in order for a physical change to occur
B.The number of atoms of each element must remain the same before and after a reaction in order for mass of the products to be the same as the mass of the reactants
C.The total mass of the reactants cannot equal the total mass of the products
D.The number of atoms in each element must change after the reaction in order for the mass to remain constant
DO NOT GIVE A LINK TO THE ANSWER PLEASE
Answer:
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.

what is the difference between prokaryotic and eukaryotic cells
Answer:
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration
Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

How many different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr)?
A 2
B 4
C. 6
D. 8
Answer:
I think it could be either C or D
Six different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr). Thus, option C is correct.
What is genotype?The genotype of the plant with yellow round seeds will be YYRR and produce YR gametes, while the genotype of the plant with green wrinkled seeds will be yyrr and produce yr gametes.
A true breeding plant always has identical alleles of a gene and is homozygous in nature. The genotype of the true-breeding parents with yellow round peas: YYRR. The genotype of the pure breeding parent plant with green wrinkled peas: yyrr.
Gametes are always pure which means that a gamete carries only one allele of a gene. Since both the parent plants are true breeding, there will not be any segregation of alleles during gamete formation. Therefore, the parent plant with yellow round peas "YYRR" would form all the gametes with "YR" alleles while the parent plant with green wrinkled peas "yyrr" would form all the gametes with "yr" alleles.
Therefore, Six different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr). Thus, option C is correct.

Answer:
3rd Option. Greater no. of different population
Part 1: Which compound does C represent?
Part 2: Name a process that could release this compound into the air.
Part 3: Explain how the elements that form it are conserved during the carbon cycle. Use complete sentences to explain your answer.
Justify how this compound was created from a recycling of carbon in the carbon cycle. Use complete sentences to explain your answer.
Answer:
part 1: Carbon dioxide
part2: combustion, respiration
part3:
- carbon in the atmosphere is removed by green plants and phytoplanktons in water bodies through the process of photosynthesis.
-The CO2 is then incorporated into carbohydrates such as sugar or starch and eventually to lipids and proteins .
-The plants are later on consumed by the animals and the organic matter in the plants are digested b,absorbed and make up the animal tissues.
-The formation of fossil fuels(fossilization) and limestone also removes CO2 from the atm.
-CO2 in the atm also dissolve in water to form acid rain thus removing CO2 from the atm.
- CO2 is added into the atm by respiration. During respiration plants and animals oxidize carbon compounds in their cells breaking them to CO2 and water which are later excreted into the atmosphere.
- When plants and animals die their remains are broken down by saprophytic organisms converting the carbon compounds to CO2 which is released into the atm.
- When eruption occurs gases are released into the atm amongst which is CO2 thus increasing its conc in the atm.
-
Explanation:
From what I could understand the first part of part three talks abt the removal of carbon dioxide from the atm while the second part talks abt its addition. I hope I got it right.
