B
Explanation:
Experiment tools and methods were not as precise as they are now. Since tech has evolved so has the ways to look at atoms meaning that they will see new and different things.
This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence. And Because more experiments gave more data, theories and models for atoms changed to be more accurate over time.

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter
Answer:
c) The total amount of matter decreases over time.
Explanation:
The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).
The biosphere refers to the total of all ecosystems of the Earth.The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
Answer:
Oxygen cycles keeps the flow of oxygen at a constant rate.
Explanation:
The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.
Answer:
A.) The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

What would be the main problem with reproduction if meiosis did not take place to form sex cells?
Answer:
Fertilization would result in a zygote with twice as many chromosomes as the parents.
Explanation:
Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.
Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.

6g of calcium chloride must be heated in
order to dissolve it in a test tube of water.
After an experiment, as a test tube of salt
solution cools, salt forms at the bottom of
the test tube
As soda is heated, the amount of Carbon
dioxide dissolved in it decreases.
Calcium Chloride is more soluble when it

It take more time stirring to dissolve salt
in 100ml than it does in 200mL of water.

The solubility of Sodium Chloride is
almost identical at 15, 20, 25 and 30°C
Supports conclusion
Brings into question this conclusion
Neutral observation
Answer:
See explanation
Explanation:
I will try to explain each point mentioned to the best of my ability.
The dissolution of calcium chloride in water is endothermic hence more solute dissolves as the temperature increases. When the solution cools, the solubility of the solid also decreases with decreasing temperature hence the solid reappears.
When soda is heated, carbon dioxide gas is evolved thereby decreasing the amount of dissolved carbon dioxide.
Let me state that increase in volume of solvent increases the amount of solute that can dissolve in it. This is why 250ml volume of solvent can dissolve more solute than 100ml of solvent.
Also, temperature is an important factor when discussing the solubility of a solute. This is why the temperature at which a certain value of solubility is quoted must be indicated. For solids, solubility increases with increase in temperature.
Lastly, the solubility of sodium chloride is independent of temperature. This is clearly seen by plotting a solubility curve.

A substitution mutation occurs when a base in the DNA sequence is replaced by a different base.
What do you mean by substitution mutations?Substitution is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.
Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide.
Substitution mutations can be good, bad, or have no effect. They cause three specific types of point mutation: silent, missense, and nonsense mutations.
