How does seed become dormant?
Answer:
Seeds may be dormant because the seed coat prevents germination, or because the embryo - by itself or together with chemicals - inhibits germination. Seed coats render seeds dormant if: their hardness prevents the embryo from expanding. impermeability to water stops development.

How does an
enzyme speed up a chemical
reaction?
Answer:
By lowering the activation energy
Explanation:
Enzymes are biological catalysts. Catalysts reduce the activation energy for reactions. The lower the activation energy for a reaction, the quicker the rate. Common enzymes convert shape when substrates unite. Enzymes lower the activation energy required to turn a reactant into a product. Consequently, an enzyme-catalyzed reaction pathway has a smaller energy activation to succeed ere the reaction can progress. Therefore, enzymes speed up reactions by lowering the activation energy.

Which step in cellular respiration produces the most ATP?(1 point)
Krebs cycle
glycolysis
electron transport chain
lactic acid fermentation
Answer:
it's Kerbs cycle which produces most ATP in cellular respiration
Answer:
The answer is electron transport chain
Explanation:
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule. Electrons are transferred from NADH or FADH2 to O2 by a series of carriers and are coupled to ATP synthase for the formation of ATP.

What are reactants in a chemical reaction?(1 point)
substances that are formed by reactions
outputs
inputs
substances that speed up reactions
Answer
D
Explanation:
inputs are the substances put in to make a chemical reaction.
The reactants are the inputs that are combined to form a product. The correct option is C.
What is a chemical reaction?A chemical reaction is a process that converts one or more substances, known as reactants, to one or more different substances, known as products. Chemical elements or compounds are examples of substances.
The most important types of events in the universe are chemical reactions. Plants grow, produce fruit, and decompose to become compost for new plants through chemical reactions.
Humans (and all other animals) reproduce, digest, grow, heal, and think as a result of chemical reactions.
Nuclear reactions are processes that involve the atomic nucleus. Reactants are the input substances that take part in a chemical reaction.
Products are the substances that are formed. The properties of the products differ from those of the reactants.
Thus, the correct option is C.

D)
E)
Indiana is home to fossilized
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

describe how the solar system was formed
Explanation:
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it. In a similar manner, moons formed orbiting the gas giant planets.

Proteins can be denatured in many ways.
Which of the following will NOT denature
a protein?
A. pH
B. temperature
C. too many enzymes
D. salt content
Answer:
Explanation:
However, at very high salt concentration, the increased surface tension of water generates a competition between protein and salt ions for hydration. Salts strip off the essential layer of water molecules from the protein surface eventually denaturing the protein
Too many enzymes cannot denature protein.
Enzymes are a type of protein so they will not get denatured in presence of one another.Enzymes are proteins that speed up any biochemical reaction in the body.What is denaturation of protein?It is a process of modifying the molecular structure of a protein.It involve breakage of many of the weak bonds within the protein molecule that are responsible for the structure of protein and its order.It can happen due to high temperature, pH, salt concentration and mechanical concentration.To know more about denaturation of protein here

Jorge is studying a pond ecosystem in his neighborhood. The pond is home to a variety of plant and animal species, as well as a stop for birds that migrate through the region.
One summer, heavy rains wash an unusual amount of fertilizer into the pond. Jorge observes the algae population growing rapidly, and quickly algae cover the pond's surface. Several weeks later, many fish and other animals die in the pond. However, within two years, the algae population has returned to its previous size, as have the populations of all the ecosystem members.
Jorge's observations provide the strongest evidence for which of the following conclusions about the pond?
A. The pond ecosystem has very high biodiversity that protects it from invasive species.
B. The pond ecosystem is resilient to changes in many abiotic and biotic factors.
C. The pond ecosystem can withstand only certain levels of algal growth.
D. The pond ecosystem may change over time, but its species will continue living there indefinitely.
Answer:
I think that the answer is C.
Explanation:
If the levels of algae were too high then it would be the reason as to why the fish died. When the algae went back to normal,the fish were able to live there again.

7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?
Hey there! I'm happy to help!
Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.
You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.
Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.
