Name the substrate the main product and the by-products of fermentation
The two main types of fermentation are alcoholic fermentation and lactate fermentation (there are other types). Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2).
Answer & explanation:
The two most important types of fermentation are latic fermentation and alcoholic fermentation.
The lactic fermentation has pyruvic acid as its substrate, this reaction has as its end product the energy in the form of ATP and its byproduct is lactic acid.
In alcoholic fermentation, yeast and some bacteria ferment sugars(substrate), producing at the end of the fermentation reaction energy (ATP) as a final product, and as byproducts carbon dioxide and ethanol.

Answer:
Tubercle: allows tendons to attach to bone
Foramen: Allows blood vessels and nerves to travel through bone.
Fossa: Allows to bones to form a joint.
Explanation:
Tubercle is a small round prominence on the bone which helps in the attachment of tendons to the bones.
Foramen means aperture or hole, through which blood vessels and nerves can pass through. For example: Vertebral foramen. Vertebral foramen of all the vertebral bones together form the vertebral canal. Blood vessels pass through the vertebral foramen. Another example is foramen magnum in the occipital bone.
Fossa is small depression on the surface of bone where articulation can occur. Example: radial fossa- is a depression which articulated with head of radius when the forearm is raised. Olecranon fossa receives olecranon of ulna when forearm is extended.

A collected gas has a pressure of 778mmHg and a temperature of 47.0C. What would be the new pressure at standard temperature
Answer:
= 664.10 mmHg
Explanation:
According to pressure law the pressure of a fixed mass of a gas is directly proportional to the absolute temperature.
Therefore;
P1/T1 = P2/V2
Standard temperature is equal to 0°C, which is 273.15 K.
In this case;
P1/T1= P2/T2
P1 = 778 mmHg
T1 = 47.0 + 273 K
= 320 K
P2 = ?
T2 = 0° C = 273.15 K
P2 =P1T2/T1
= (778 × 273.15)/320 K
= 664.10 mmHg

What is the term used for the elements and compounds before a chemical reaction takes place?
Explanation:
Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.
And, when the chemical reaction takes place between the given elements and compounds then they change into products.
For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.
But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.
In a chemical reaction, the term used for the elements and compounds present before the reaction takes place is 'reactants'. These undergo a chemical reaction to form the 'products'.
Explanation:In a chemical reaction, the substances that are present before the reaction takes place are referred to as the reactants. These could be individual elements or compounds that chemically interact with each other. For instance, in the formation of salt (NaCl), sodium (Na) and chloride (Cl) are the reactants. After the reaction has taken place, the substances that are produced are referred to as products.
Furthering the explanation with another example, let's consider water's formation. The reactants in this chemical reaction are hydrogen and oxygen, which are the elements. They react to form water, which is the product and a compound. The chemical equation would be: 2H + O -> H₂O. The arrow indicates the direction of the reaction, from reactants to products. Thus the term used for elements and compounds before a chemical reaction is 'reactants'.

As the rate of cooling of igneous rocks increases, the size of the crystals that form
As the rate of cooling of igneous rocks increases, the size of the crystals that form decrease. Sense the size of the crystals will decrease, this would include that the rate of cooling of igneous rocks increases.
Answer:
The correct answer is "decreases".
Explanation:
As the rate of cooling of igneous rocks increases, the size of the crystals that form decreases. Volcanic or igneous rocks go trough a cooling process when they reach the Earth's surface, crystallizing and forming different crystal forms. The size of the crystals depend on the cooling rate, slow cooling allow the formation of large crystals, while fast cooling yields small crystals.

Answer:
21. C
22. A
23. B
24. C
Explanation:
21. The structure of cell shape is not maintained by the cell membrane, Rather it is the product of the cytoskeleton which is the filaments and microtubules in the cell. They change the shape of the cell by contracting and relaxing. They also control the internal organization of organelles inside the cell.
22. Psychrophile bacteria thrive in low temperatures which they are adapted to. They can be expected in the polar regions and deep seas. Their metabolism can function in these low temperatures because their cells have antifreeze protein that protects the cells from ice-induced desiccation and damage.
23. Thermophiles are extremophiles that thrive in high temperatures. They can be expected in hydrothermal vents. They have heat-stable proteins and enzymes and DNA (that has high G-C content) that is not easily denatured at high temperatures.
24. This phase is called the stationary phase. The reproduction rate is equal to the death rate. This is because the population has reached its carrying capacity. This is why there is no growth in population.

How do mutations drive evolution?
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
well a mutation in a animals DNA is evidence that it may be trying to adapt to its environment. or the mutation is caused be a disease or excessive amounts of radiation. but either way the mutation can be passed down to the next generation. And the mutation can continue to 'evolve' and create new possibility in what the animal can do.

Answer:
The correct answer is abiotic factors.
Explanation:
A non-living constituent in the environment is known as an abiotic factor. This can be either a physical presence or chemical. The abiotic factors come in three fundamental categories. These are edaphic, climatic, and social. The edaphic factors comprise conditions of the soil, the climatic factor comprises sunlight, humidity, and other factors taking part in the climate. The social factors comprises the water resources in the region, and how the land is used. The five general abiotic factors are chemical elements, atmosphere, temperature/sunlight, water, and wind.
