Explanation:
Because of a snowstorm, your regular laboratory session was cancelled and the gram staining procedure performed on cultures incubated for a longer period of time. Examination of the stained B. cereus slides revealed a great deal of color variability, ranging from an intense blue to shades of pink. Account for this result.
Answer:
Bacteria start to die, thereby changing the dye concentration in the medium and producing different colors
Explanation:
Bacillus cereus are Gram-positive, rod-shaped bacteria that form orange-pink colonies in agar media (e.g., BACARA medium, which is used for detection and enumeration of B. cereus). In this case, it is expected that after a long time without taking care of the culture, the bacteria started to die. Subsequently, lysed bacterial cells lost their dye which accumulated in some areas of the medium, thereby showing different colors ranging from an intense blue (areas with dead bacteria) to shades of pink (areas with bacteria still alive and viable).
The color of some colonies are changing bacause of long incubation due to death of bacteria.
Bacara agar medium:
It is used for detection and enumeration of B. cereus. Bacteria gives orange-pink colonies in the media.
This detection method only detects the live bacteria, but here bacteria are dieing because of lake of food in media.
Therefore, the color of some colonies are changing bacause of long incubation due to death of bacteria.

1.The illustration below shows that sexual reproduction involving two parent pea plants resulted in the production of four offspring.
A. All four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent
B. All four offspring received all of their genetic information only from Parent 2 and are therefore identical to that parent.
C. All four offspring are genetically unique and did not receive any of their genetic information from either parent.
D. Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
Answer:
C
Explanation:
Because of the x and y chromosomes and they split apart and that's how you get 4 offspring.
The fusion of two different gametes leads to the formation of new offspring is called reproduction. There are two types of reproduction that is sexual and sexual.
The correct option is A
The branch of biology which deals with the study of genes is called genetics. there are two types of alleles that give all the character to the phenotypes. The dominant allele is the allele that suppresses the recessive allele and shows its effect.
In question, the F1 generation shows only one type of character which belongs to parent 1 because that is the dominant allele.
Hence, the correct option is A that is all four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Methicillin resistance causes an infection to spread more rapidly. Antibiotics cause mutations in Staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus. Diseases like AIDS have made people more vulnerable to infections from Staphlococcus aureus.
Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus.
Explanation: The methicillin resistant Staphlococcus aureus is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;
In a strain of Staphlococcus aureus, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.
This is why the rate of methicillin-resistant Staphlococcus aureus has increased along the years.

Guys hurry what is genotype and what is phenotype
Answer: Phenotype= the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Genotype= In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent.

Answer:
photosynthesis
as in the process of photosynthesis plants take in carbon dioxide and give out oxygen.
hope it helps you
please mark me as brainlist
The process of taking gaseous carbon dioxide or oxygen by leaves is termed peristomal diffusion or diffusion through stomata present on leaves.
Plants take up carbon dioxide or oxygen from the air through their leaves as they have several stomata on their surface. The small holes or openings in the underside of the leaf are called stomata.
Diffusion through stomata also helps oxygen, produced in photosynthesis, to leave the leaf.The diffusion of gaseous carbon dioxide or oxygen is proportional to the concentration difference between the atmosphere and leaves.The loss of water vapor in transpiration also occurs through stomata.peristomal diffusion or diffusion through the leaves allows the gaseous exchange.Thus, the correct answer is - peristomal diffusion or diffusion through stomata present on leaves.

Which of the following is the best evidence that supports the rule that only 10% of energy is transferred from one organism to another? (1
There are fewer organisms at the top of the food chain because there is less energy available for life processos
O Ten percent of organisms are fully consumed while others contain some molecules that cannot be digested
Not all organisms at the lower trophic levels will be eaten and die
O Dead organisms and waste are broken down by decomposers and are recycled through the ecosystem
Answer:
I believe the answer is A
Explanation:
There are fewer organisms at the top of the food chain because there is
less energy available for life processes is the best statement that supports
it.
What is Trophic level?This is the position an organism occupies in a food chain. The organisms
are usually fewer while those at the bottom have more organisms present
in the chain.
As food chain moves from bottom to the top, the energy level decreases
which depicts 10% of energy is being transferred from one organism to
another
