Streptomyces griseus produces the antibiotic Streptomycin, which inhibits protein synthesis by binding to ribosomes and preventing the binding of fMet‐tRNA. Why isn’t S. griseus harmed by its own antibiotic?
Answer:
See the answer below.
Explanation:
Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.
Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.
In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

what is the source of mold on bread
Answer:
Well, mold develops and grows eventually forming a colony due to spores landing on the bread and multiplying, hence growing the mold.
Where does mold on bread come from?
On bread, molds (many colonies of various sorts) develop from microscopic fungi that float in the atmosphere.
The fungus that causes mold develops as extremely little filaments called hyphae, which enable the fungus to float and be transported by the air. The hyphae spread by forming an apparent, hairy network when they land on bread or other organic materials. The color of the spores that develop on the end of the hyphae determines the color of the mold network .There are molds that grow as single-cell spores as opposed to mold that grows as multicellular hyphae with a spore at the end. They are known as yeast.

The processes of the alterations in chromosomal organisation that take place as a cell enters mitosis.
The correct order is:
1. Chromatin is created by the regular wrapping of DNA around histones.
2. The DNA is compacted by interactions between histone component components.
3. The DNA becomes supercoiled as the chromosome coils ever-tighter.
4. Chromosomes that have been duplicated and compressed attach at a point known as the centromere.
What transpires to DNA throughout mitosis?
Therefore, during mitosis, cells don't simply randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order. Prophase, Metaphase, Anaphase, and Telophase are the four basic phases of mitosis.
In what way do chromosomes separate during mitosis?
A mitotic spindle, a specialised structure made of microtubules, is responsible for separating the chromosomes. The cell's cytoplasm divides during this phase. It starts as soon as mitosis is complete.

Explain how different links can show a relation between two species. Describe evidence that shows other correlations and causations between the species.
Different links show relationships between two species. In the scientific world, there are three types of links, including mutualism, parasitism, and commensalism.
Mutualism is a relationship in which both species benefit. Parasitism is where one species benefits, and the other is harmed. Commensalism is a relationship in which one species benefits, and the other is not harmed or helped.One example of a mutualistic relationship is the bee and flower relationship. Bees collect nectar and pollen from flowers for their food, while at the same time, the bee helps in pollination. The bee gets food from the flower, and the flower is pollinated. This is a mutualistic relationship. A parasitic relationship is the relationship between tapeworms and humans. Tapeworms live inside the host and get their food from the host, thereby, causing harm to the host. Evidence that shows correlation and causation between the species includes physical changes in the organism or adaptations to the environment. For example, an animal that feeds on a certain plant may evolve to have a longer tongue to reach the nectar of that plant. In summary, different links show relationships between species, including mutualism, parasitism, and commensalism. The evidence for the correlation and causation between species includes physical changes or adaptations in the organism or environment.For more questions on species

Silvio wants to eat a healthy meal in the college dining hall. Which of the following choices is the BEST thing he can order?
A) salad made up of lettuce and creamy dressing
B) fried chicken in mushroom sauce
C) baked potato with salsa
D) apple and a donut
The best thing Silvio can order is probably salad made up of lettuce and creamy dressing. Option A is correct.
Salads are a good source of fiber, vitamins, and minerals, and can help provide the nutrients Silvio needs for a healthy meal. To make the salad even healthier, Silvio could choose a low-fat or vinaigrette dressing instead of creamy dressing, which is often high in calories and fat.
Fried chicken in mushroom sauce is high in calories and unhealthy fats and should be consumed in moderation. Baked potato with salsa can be a healthier choice if Silvio chooses a plain baked potato and limits the amount of added toppings, such as cheese and butter.
Apple and a donut is not a balanced or nutritious meal. While an apple is a good source of fiber and vitamins, a donut is high in sugar and unhealthy fats and should be consumed in moderation as part of a balanced diet.

If it is accepted that the information for how a protein is intended to fold lies within its primary sequence, explain why a purified protein denatured in vitro might not be able to renature accurately.
Answer:
Denaturation and renaturation are properties of protein but in some cases denaturation is irreversible and protein is unable to renature.
The primary sequence of a protein determines which portion of protein fold closely together in order to form three-dimensional conformation and the conformations are held by hydrogen bonds.
Denaturation of protein in-vitro is generally obtained by increasing temperature. Heat or high temperature disrupts hydrogen bonds that held between protein folds because high temperature increases the kinetic energy and the bonds are disrupted due to rapid heating. Disruption of hydrogen bonds will change the 3D structure of the protein and denatured proteins lose its function.
Chemicals are also used to disrupt hydrogen bonds such as alcohol.
So, high temperature and chemicals denature protein by affecting the hydrogen bonds holding 3D shape of primary sequence in protein and the change in protein becomes irreversible.

describe how impulse are transmitted across a synapse
A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.
What are the impulse?Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.
The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

The genotypes of the parents would be:
Parent 1: AA
Parent 2: AO
To determine the genotypes of the parents in this scenario, we can use the information about the blood types of their children and the inheritance patterns of blood types.
From the given information:
Child 1: Type A blood (genotype could be AA or AO)
Child 2: Type O blood (genotype must be OO)
Child 3: Type AB blood (genotype must be AB)
Child 4: Type B blood (genotype could be BB or BO)
Based on this, we can deduce the genotypes of the parents as follows:
Since child 1 has type A blood, the parents must have at least one A allele each. Therefore, one parent could have genotype AA (two A alleles) and the other parent could have genotype AO (one A allele and one O allele).
