Answer:
1. a catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
2. An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes.
3. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes. Without enzymes, many of these reactions would not take place at a perceptible rate. Enzymes catalyze all aspects of cell metabolism.
Explanation:A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes. Enzymes help speed up chemical reactions in the human body.

Answer:
The correct answer is - А. experiment.
Explanation:
An experiment is a type of research method used for scientific investigation to check how a natural phenomenon works and how a particular variable affected by causing or manipulating one variable.
The affected variable called the dependent variable and the variable that is changed is called the independent variable. Other than independent variables other variables should be controlled so there would be no influence on the result other than independent varibles.
The research method in which a researcher changes the value of one
variable to determine how the change affects another variable is during
Experiments.
What is an Experiment?An Experiment is usually conducted to confirm or refute claims of an
hypothesis. This is usually carried out by using two types of variables
called:

1. Friction can cause a moving object to stop.
TRUE OR FALSE
Answer:
true
Explanation:
cus over a time when the objects energy get's reduced it would be halted by friction
Friction can absolutely causes a moving object to stop (stationary). So, the answer is True.
What is Friction?
It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.
To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.
Therefore, friction can cause a moving object to stop.

At the end of meiosis ll, each of the haploid sex cells had only half the number of chromosomes as the original diploid cell. Why is this important?
Answer:
The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.

1. Compare neutron stars and black holes.
2. explain the role of white dwarfs in recycling matter
3. Distinguish between an astronomical unit and a light year
4. How does a convection zone transfer energy?
Thanks!
Answer:
1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars will turn into black holes if the force of gravity breaks the resistance of electrons.
2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.
3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.
4. A convection zone transfers energy by radiation and conduction.

Plant hormones are chemical regulators that stimulate or inhibit growth depending on their concentration and type of tissue in which they
are found
STEMS
STIMULATION
ROOTS
LOW
HIGH
HORMONE CONCENTRATION
Based on the information in the graph, which is a correct conclusion about plant hormones?
F. They stimulate maximum root growth and stem growth at the same concentration.
OG. They stimulate maximum stem growth at low concentrations,
OH. They stimulate maximum root growth at high concentrations.
OJ. They stimulate maximum root and stem growth at different concentrations.
Answer:
OJ. They stimulate maximum root and stem growth at different concentrations.
Explanation:
Looking at the graph found in the attachment below, conclusions can be drawn about the effect ofnthe difference in concentration of plant hormones in the two different parts of the plants under consideration, the roots and the stem.p
Considering the roots;
maximum growth of the roots of plants as seen by the upward curve ofbthe arrow, is obtained when plant hormones are at low concentrations. However, with increase in the concentration of plant hormones, the growth of root diminishes as seen bynthe downward slope of the curve.
Considering the stems:
At low concentration of hoeprmones, the growth of stem is very minimal. However, with increase in concentration of plants hormones, a rapid upward shoot is seen in curve indicating a rapid increase in growth. Maximum growth occurs at high concentration of plant hormones.
Therefore, the proper conclusion is that, plant hormones stimulate maximum root and stem growth at different concentrations.
what are the streght and weaknesses of the cells
Answer:
- Strength: cells can carry out specialized tasks
- Weakness: cells cannot carry out functions of another cell types
Explanation:
Cells are highly specialized biological units designed to carry out specific metabolic functions (e.g., growth, replication, development, etc). Each cell type exhibits a specific gene expression pattern related to its specific function. For example, in undifferentiated stem cells, specific signaling pathways are associated with the differentiation process. On the other hand, cell weakness is associated with the same phenomenon, cells are not able to carry out all cellular functions and therefore they need to work together to sustain the life of the whole organism.
Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

Identify three features of the newly formed skin that are different from a healthy patch of skin. Suggest a reason for each of these differences.
Answer:
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The skin has three main functions: Protection; Thermoregulation; Sensation.
The skin acts as a protective barrier from:
Mechanical, thermal and other physical injury;
Harmful agents;
Excessive loss of moisture and protein;
Harmful effects of UV radiation.

1. Give two possible ways that negative human impact on the pH of Earth’s oceans can be reduced.
Answer: By Lowering the carbon dioxide in the air, and reducing the plastics that goes into the oceans.
Reducing carbon dioxide emissions into the atmosphere and prevent the throwing of plastic in the ocean are solved the problem of low pH in the ocean.
What ways reduce the pH of Earth’s oceans?Lowering the carbon dioxide in the air and plastics are the two possible ways that negative human impact on the pH of Earth’s oceans can be reduced because carbon dioxide gas reacts with ocean water forming carbonic acid which leads to lowering pH.
So in my opinion, reducing carbon dioxide emissions into the atmosphere and preventing the throwing of plastic in the ocean are solved the problem of low pH in the ocean.

What is magma?Magma has been defined as the molten or the semi-molten material which is natural and from magma all igneous rocks are formed. Beneath the surface of the earth magma has been found and there are very proofs of magmatism and it has been observed on the other terrestrial planets as well as some of the natural satellites.
Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.
