Which box in this Punnett square would contain two dominant alleles?
The teacher noticed that Carrie seemed quite restless today and was having difficulty concentrating on any task that she started. She continuously squirmed, whether in her chair or sitting on the floor. On a number of occasions, the teacher also observed Carrie tugging at her underwear and scratching her bottom. She recalled that Carrie’s mother had mentioned something about getting her younger brother tested for pinworms and wondered if this might be what she was observing.
Required:
If Carrie does have pinworms, for what length of time should the other children be observed for similar problems?
Answer: Other children should be observed after the average of 6 weeks from the time of exposure to Carrie who is suspected to be infected by Pin worm.
Explanation:
Pin worm also called enterobiasis vermicularis is a parasitic nematode. The eggs are found in the specimen collected from the perianal skin and in the faeces of an infected individual. In its worldwide distribution, children are more commonly infected than adults. This is so because autoinfection by swallowing infective eggs is common in children. The eggs cause intense irritation and scratching of the infected area leads to the fingers becoming contaminated with eggs. This was observed by Carrie's teacher, as she usually scratch her bottom.
Other children should be observed after the average of 6 weeks from the time of exposure to infective eggs. This is because of the direct life cycle exhibited by the worm. Following ingestion of infective eggs, the larvae hatch in the intestine. Occasionally larvae hatch from the eggs on the perianal skin and migrate back into the intestine where they grow into mature worms. This type of infection is called RETROINFECTION. The larvae develop into fully mature worms in the large intestine. The female worms migrate to the rectum, pass out of the anus and lay their eggs on the perianal skin and perineum. The eggs are produced about 6 weeks after infection. They can remain viable on bedding, clothing, household objects, and in dust for several weeks.
Therefore from the life cycle of the worm, similar problem found in Carrie can be observed in other children after about six weeks of exposure to the infective eggs of the worm.
why is one mutation not enough to result in cancer
Answer:
A single mutation is unlikely to result in cancer. Cancer is usually caused by a series of mutations that accumulate throughout the course of a person's life. As a result, cancer is more common in older adults. They've seen more chances for mutations to accumulate.

Whether there is a net flow of fluid into or out of a capillary at a given spot along its length depends on _____.whether or not the fluid contains carbon dioxide whether or not the fluid contains oxygen whether the fluid contains nutrients or wastesthe balance between blood pressure and osmotic pressurethe needs of the tissue
Answer: Depends on the balance between blood pressure and osmotic pressure.
Explanation:
The capillaries are part of the microcirculation that transports nutrients to the tissues and removes cell excreta. The walls of the capillaries are extremely thin, constructed of single - layer, highly permeable endothelial cells. Therefore, water, cell nutrients and cell excreta can all interchange quickly and easily between the tissues and the circulating blood.
The tissues of the body is made up of soo many capillaries which helps to deliver blood and it's contents to it. The hydrostatic pressure in the capillaries tends to force fluid and it's dissolved substances through the capillary pores into the interstitial spaces. Conversely, osmotic pressure caused by the plasma proteins( called COLLOID OSMOTIC PRESSURE) tends to cause fluid movement by osmosis from the interstitial spaces into the blood. This osmotic pressure excreted by the plasma proteins normally prevents significant loss of fluid volume from the blood into the interstitial spaces.
Therefore, a balance between hydrostatic pressure in the capillaries which is influenced by blood pressure and osmotic pressure in order for a net flow of fluid into or out of a capillary to occur.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.

bloaccumulation
risk assessment
toxicity
biomagnification
Answer:
bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

Scientific study of the population cycles of the snowshoe hare and its predator, the lynx, has revealed that ________. Question 9 options: A) predation is the dominant factor affecting prey population cycling B) hares and lynx are so mutually dependent that each species cannot survive without the other C) the hare population is r-selected and the lynx population is K-selected D) both hare and lynx population sizes are affected mainly by abiotic factors
Answer:
A) predation is the dominant factor affecting prey population cycling
Explanation:
Predation is a type of interaction between species where one species called ‘predator’ uses another species, the ‘prey’, as a source of food. Within an ecosystem, the number of predators and prey may vary over time in cycles of time (in these cases, the population cycles of both species are closely linked). In consequence, predation is a density-dependent factor. In the case of the snowshoe hare and its predator, the lynx, when the number of predators is too high, the number of prey drastically decreases. Subsequently, this leads to the decrease of predators that leave their home range (they don’t have enough food to survive), thereby the snowshoe hare population increases again until the peak of the population cycle (carrying capacity), and so successively.
