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.
In an electron microscope, the sample is bombarded with a stream of electrons that are expelled from an electron gun. The electrons interact with the sample component, the result of which is transformed into an image. Why do you think electron microscopes allow for greater magnification than compound microscopes?
Answer:
It is because the electron microscope uses a shorter wavelength electron
Explanation:
In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.
The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.
Answer:
Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

Scientists often ask questions to clarify data or guide scientific research. What are two scientific questions you have that
could clarify relationships about the DNA or traits of these orchids?
Answer:What traits would orchids have if the MADS-box genes were not duplicated?
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?
Explanation: The example given by Plato
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
What is Genetic mutations?The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.
For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.
The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.
Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

Explain the process of gaseous exchange in the alveoli of the lungs.
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Answer:
carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

How many rounds of division are there when one cell in the testis becomes four sperm cells?
Answer:As a result of the two meiotic divisions, each primary spermatocyte produces four spermatids. During spermatogenesis there are two cellular divisions, but only one replication of DNA so that each spermatid has 23 chromosomes (haploid), one from each pair in the original primary spermatocyte

Hope that helps!

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.

Binary fission occurs in which of the following type of organsim?
Answer:
A. Prokaryotes like bacteria
Explanation:
Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).
Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.
The answer is thus A.
Where are the instructions that control a
