What is the benefit of using a shortcut in a reaction between two chemicals? A shortcut would ensure a safer reaction. A shortcut may provide a faster reaction. A reaction with a shortcut would yield more chemical output. A reaction with a shortcut would require less chemical input.
Answer:
A shortcut may provide a faster reaction
Explanation:
Chemical reactions occur in a particular manner and speed if allowed to occur normally. However, shortcuts can be used for the essence of making the reaction proceed much faster than it naturally would. Catalysts are the substances used to provide these shortcuts.
A catalyst is a substance that increases the rate at which a chemical reaction occurs without being chemically used up in the reaction. A catalyst speedens up the chemical reaction by decreasing the activation energy. The activation energy is that energy needed for a chemical reaction to kick start. The higher the activation energy, the slower the reaction proceeds.
A catalyst, thus, creates a shortcut by lowering the activation energy of the chemical reaction, allowing it to proceed faster than when a catalyst is not used.

Which process produces human egg and sperm cells?
Answer:
Hey there! Your answer will be below.
Explanation:
The answer to your question is gametogenesis or meiosis ( which produces gametes....From meiosis it becomes or forms into gametes.)
So the answer should be gametogenesis/ meiosis....
Hope that helps!
By: xBrainly
Meiosis or gametogenesis is the process that produce human egg and sperm cell.
What is meiosis?Meiosis is a type of reproduction in which a parent cell divide into four daughter cells that are genetically different from the parent cell. The daughter cells have half number of chromosome of the parent cell.
This process produce the gametes which are the sperm cell and egg cell.
Therefore, Meiosis or gametogenesis is the process that produce human egg and sperm cell.

What does Saccharomyces cerevisiae (Baker’s yeast) need to survive?
Answer:
Food (Sugars)
Explanation:
S. cerevisiae feeds on sugars for energy, in the process producing carbon dioxide and alcohol (this is fermentation in a nutshell). The carbon dioxide bubbles get trapped in the dough, creating the lift that makes the dough rise. The alcohol, meanwhile, evaporates when baking, transforming into gas that also contributes to the rise of the bread. The alcohol, along with acids produced during the fermentation process, impart that wonderful flavor and aroma associated with yeast-leavened breads.
Identify characteristic of alcohol. a. It is a key ingredient in dietary supplements. b. It provides water but not calories. c. It enhances the repair of body tissues. d. It provides calories. e. It is an essential nutrient.

Mendel’s pea plants had either purple or white flowers. This means that the plants can self-pollinate. have two recessive traits. have two alleles for the gene. have two copies of a gene from one parent.
Answer:
I think it's that they have two alleles for the gene
The statement that Mendel’s pea plants had either purple or white flowers means that the plants have two alleles for the gene.
MENDEL'S LAW:Gregor Mendel is regarded as the Father of genetics due to his immense contribution to knowledge of genetic inheritance.
According to Gregor Mendel, a gene consists of two alleles, which individually encode different phenotypes of a particular trait.
In this question involving flower color gene, two alleles coding for purple (P) and white color (p) are present in the gene.

If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result? Less water would be available on the earth’s surface. Less solar energy would reach the earth’s atmosphere. More oxygen gas would be found in the atmosphere. More carbon dioxide gas would be found in the atmosphere.
Answer:
More carbon dioxide gas would be found in the atmosphere.
Explanation:
Photosynthetic organisms convert carbon dioxide in air to oxygen through photosynthesis, while other non-photosynthetic organisms only consume oxygen and release carbon dioxide through respiration, they do not undergo photosynthesis.
When the number of photosynthetic organisms on the earth decreased drastically, the carbon dioxide released from other non-photosynthetic organisms cannot be converted to oxygen, so carbon dioxide in air accumulates.

11. Which of the following is not a cause of cell necrosis?
Infection
Blood clot
Injury
Perfusion
Infection, blood clot, and injury all are the causes of cell necrosis except perfusion. Thus, the correct option is D.
Cell Necrosis is the death of the cells which are present in the body tissues. While the dead body tissue can be removed, it cannot be brought back to the good health.
The necrotic tissue appears as white and friable cells, like the clumped cheese. Dead cells in the body disintegrate however are not completely digested by lysosomes, thus leaving granular particles. Microscopic examination of the dead cells show amorphous granular debris that is enclosed within a distinctive inflammatory border.
Cell Necrosis can occur due to different causes such as injury, infections or diseases. Lack of blood flow to body tissues and extreme environmental conditions.
Therefore, the correct option is D.
