sometimes you hear that only a small minority of different bacterial species cause diseases in humans or animals. are there reasons for thinking that this might not be true.

Answers

Answer 1

The proposed idea is true. This is because:

The human body is a sophisticated ecology that is prospering. In addition to human cells, it also contains bacterial, fungal, and protozoan cells, which comprise thousands of microbial species. These microorganisms, also known as the normal flora, are typically restricted to particular body parts, such as the skin, mouth, large intestine, and vagina. Humans are also constantly infected with viruses, the majority of which just sometimes or never cause symptoms.Typically, pathogens are distinct from the native flora. Only when our immune systems are compromised or when they get access to a typically sterile area of the body do our normal microbial residents cause problems.For example, a perforation in the bowels might enable the native gut flora to enter the peritoneal cavity resulting in peritonitis.Dedicated pathogens, on the other hand, don't need the host to be hurt or have their immune system impaired. They have created highly sophisticated methods for overcoming cellular and biochemical barriers and for inducing particular reactions in the host organism that aid in the pathogen's survival and growth.

So, some pathogens might make humans and animals sick.

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.

Answers

The fetal face is approximately one-third the size of the fetal skull. The mature cranium is around two-thirds the size of the adult skull.

The cranium, the skull's protective outer covering consists of three bones: the frontal bone, two parietal bones, and one occipital bone.

The frontal bone is a single bone on the forehead and rests on top of the eye orbits. It also makes up a significant portion of both sides of the maxilla. The two parietal bones make up the majority of both sides and the top of the skull, as well as a considerable portion of each side of the maxilla. The occipital bone is the most distant cranial bone and the occiput's primary bone. It, like all other cranial bones, is classified as a flat bone, which means that its major role is either protection or providing a large surface for muscle attachment.

Answers

Derick likely damaged the Trigeminal nerve after suffering a head injury since his symptoms are weak and uncoordinated movement of the jaw and numbness of the tongue and lower gums.

The trigeminal nerve is a part of the nervous system primarily responsible for sensing pain, touch and temperature in the face and sends the signal to the brain. The trigeminal nerve is the fifth of 12 cranial nerves and called the cranial nerve V.

There are two trigeminal nerves, one on each side of your body. They originate in the brain and travel throughout the head. The trigeminal nerve has three branches that perform various functions:

• Ophthalmic – related to forehead, eye and upper eyelids sends nerve impulses from the upper part of the face and scalp to the brain.

• Maxillary – which refers to the upper jaw extends to the lower eyelids, nose, cheeks and upper lip and gums is responsible for sensations in the middle part of the face.

• Mandibular – or the lower jaw branch aids sensation to the lower part of the face, like the jaws, lower lip and gum. These nerves also have a motor function and help in biting, chewing and swallowing.

In simple summary form, the calvin cycle requires an input of __________ for every product that is formed and the output product is __________, which is used for glucose synthesis.

Answers

In simple summary form, the Calvin cycle requires an input of 3CO2 for every product that is formed and the output product is a three-carbon molecule which is used for glucose synthesis.

The Calvin cycle refers to the three essential processes of photosynthesis that are light-independent. Although the Calvin Cycle is not explicitly dependent on light, it is dependent on light indirectly because the required energy carriers (ATP and NADPH) are results of light-dependent processes.

Light-independent reactions are begun during fixation, the initial stage of the Calvin cycle; CO2 is fixed from an inorganic to an organic molecule.

In the second step, ATP and NADPH are utilized to convert 3-PGA to G3P, which is subsequently transformed to ADP and NADP+. Three molecules of CO2 enter the cycle for every six molecules of G3P generated. As an output, one G3P exits the cycle. The remaining five are kept and rearranged to make RuBP. Furthermore, the three-carbon molecule glyceraldehyde-3-phosphate (G3P) is removed from the cycle for glucose production.

RuBP is replenished near the end of the Calvin Cycle, allowing the system to prepare for further CO2 fixation.

The answer is Endoplasmic Reticulum (ER). ER is a cell organelle that features membrane bound canals and brings about the function of tubular transport in cytoplasm.

The cytoplasm of eukaryotic cells contains a sizable membrane-bound compartment known as the endoplasmic reticulum (ER). The nuclear envelope (NE), peripheral ER cisterns, and a linked tubular network are its three main morphologies.The smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum are two functionally different types of the endoplasmic reticulum (RER). The presence of ribosomes, which synthesize proteins, connected to the RER's outer surface distinguishes the two morphologically.In general, the endoplasmic reticulum's job is to make proteins so that the remainder of the cell can operate.

According to modern concept of evolution natural selection is not a bloody battle as was emphasized by Darwin and Wallace.

It is a peaceful process that has little to do with, "struggle for existence" or "elimination of unfit" or "survival of the fittest".

Natural selection really means differential reproduction ( some members of the population produce lage no of offspring, some are few and still others none.

Those that produce large no of offspring contribute greater percentage of genes to the gene pool of the next generation than those that produce fewer offspring.

If differential reproduction continues for many generation ,then genes of the individual which produce more offspring will become predominant in the gene pool of the population.

This leads to change in the gene frequency of the population.

Individual which are best adopted to the environment having greater no of surviving ones.

Survival of the organism to the reproductive age and their selection for mating is the important factors which results in differential reproduction.
