Answer:
Option). the mutation must occur in a specific gene that controls cell division.
Explanation:
Mutations can be defined as permanent alterations in genetic material due to changes in sequence of DNA. Mutations may be random or induced due to exposure of cancer-causing chemicals.
Malignant cells are tumor-forming cells that show uncontrolled grow and division. These cells are formed by loss of control of cell division and bypass normal cell death.
There are several types of mutations that take place in a cell, but only few mutations cause formation of malignant cells. This is because, to be develop into a malignant, mutations must take place in genes that regulate cell division.
Thus, the correct answer is last option.

Which is an example of how the body maintains homeostasis? increasing thirst when cells are low on water decreasing thirst when cells are low on water shivering when it is hot sweating when it is cold
The right option is; increasing thirst when cells are low on water
Homeostasis is ability of a biological system or the body to adjust its internal environment in order to maintain a condition of stability regardless of the external changing conditions. Homeostasis occurs in humans when thirst is increased because cells are low on water, when sweating to cool off when it is hot, or when shivering to produce heat when it is cold.
The statement that correctly describes how the body maintains homeostasis is:
Increasing thirst when cells are low on water.What is homeostasis?Homeostasis is the ability of the organism to present a characteristic and constant physical-chemical situation within certain limits.
Characteristics of homeostasisThirst behavior, described as an intense motivation to seek, obtain, and consume water, is one of the most important homeostatic mechanisms for maintaining water balance.Water balance indicates homeostasis or relative constancy of body fluid levels, a precise situation for survival.Therefore, we can conclude that homeostasis is the set of self-regulatory mechanisms such as increasing thirst that lead to the maintenance of constancy in the properties and composition of the internal environment.

the diagram below shows the movement of matter in a portion of water cycle. what does P most likely represent?
A) Rivers
B)springs
C) transpiration
D) precipitation
The correct answer is B) springs.
A place on the Earth’s surface where water appears at on its own is called a spring. After rain or from snow water seeps into the ground. The water which seeps into the ground is collected in fractures and fissures in the bedrock. Water in the bedrock collected into the aquifers. When a fissure in the bedrock breaks the surface, the natural high water pressure under ground forces water above the earth surface and forms spring.

Occurs when layers of materials, such as extra sheets or blankets, are placed over the surgical mattress or padding, diminishing the pressure-reducing properties of the surfaces
Shear occurs when layers of material, such as extra sheets or blankets, are placed over the mattress or padding. Hence the correct option is b.
Shear is a phenomenon that occurs when layers of material, like additional sheets or blankets, are placed over a mattress or padding. This happens when the upper layers of the material move in a parallel direction to the surface below. In the context of healthcare, shear forces can be problematic for patients, especially those with limited mobility or those bedridden.
When a person is moved or repositioned in bed, the skin can experience shear forces, potentially leading to skin injuries, particularly in areas where bones are close to the skin's surface. It's crucial to address shear forces in healthcare settings to minimize the risk of complications, and healthcare professionals often employ various strategies such as proper positioning and the use of specialized support surfaces to mitigate the impact of shear on the skin. Hence the correct option is b.

Sutures are the type of fibrous joints that are immobile and found only between certain bones of the skull. They provide a tight union between skull bones, effectively protecting the brain.
Explanation:The type of fibrous joints that are immobile and found only between certain bones of the skull are called sutures. Sutures are fibrous joints with short fibres of connective tissue that hold the skull bones tightly in place. This type of joint is an example of synarthrosis, an immobile or essentially immobile joint. Unlike other types of fibrous joints, such as syndesmoses (found between the shaft regions of the long bones in the forearm and leg) and gomphoses (found between the roots of a tooth and the bony socket in the jaw), sutures are immovable and provide a tight union between skull bones, protecting the brain.

A student refuses to wear safety goggles in lab. what will the instructor do?
Final answer:
When a student refuses to wear safety goggles, the instructor should remind them of the safety protocols and the importance of wearing protective gear. If refusal persists, the student may be asked to leave the lab to maintain a safe environment.
Explanation:
If a student refuses to wear safety goggles in lab, the instructor has the responsibility to enforce lab safety protocols. Safety guidelines, including the use of personal protective equipment, are essential for reducing the risk of injury in a laboratory setting. It is important to protect students from potential harm by ensuring that they adhere to safety precautions. In this case, the instructor would most likely remind the student of the importance of wearing goggles and the potential consequences of not doing so. If the student continues to refuse, the instructor could require them to leave the lab for the day to maintain a safe environment for everyone. In some educational institutions, there may also be disciplinary actions for failing to follow safety instructions.
Moreover, before participating in lab courses, students are often required to sign a department form stating the assumption of risk and a release from claims. This helps to ensure that they have been informed of and understand the necessary safety measures to be followed.

just a few hours after the birth of a baby, the mammary glands start producing milk. which hormone stimulates this event
Answer:
The correct answer is the prolactin hormone.
Explanation:
Prolactin (PRL) or luteotropic hormone is a hormone, known for its different roles in enabling mammals, especially females. It is secreted in response to nursing, ovulation or mating, from the pituitary gland. Prolactin is manufactured by the pituitary gland in the brain.
Prolactin is majorly used to help women producing milk after a few hours of childbirth. The stimulation of the nipples and mammary gland leads to the release of prolactin.
Thus, the correct answer is the prolactin hormone.

Describe the impact of a waterborne pollutant on an aquatic community. write a 100-word report on how that pollutant affected aquatic life, what the effect was, and whether the effect is linked to biomagnification.
Water pollution can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. Pollutants such as heavy metals can biomagnify in the food chain, leading to higher concentrations in predatory fish species. This can have harmful effects on the fish themselves, as well as on the organisms that consume them.
Explanation:Water pollution is the contamination of water by an excess amount of a substance that can cause harm to human beings and/or the ecosystem. Pollutants can enter water supplies from point sources, which are readily identifiable and relatively small locations, or nonpoint sources, which are large and more diffuse areas. Waterborne pollutants can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. For example, pollutants such as heavy metals like mercury and cadmium can biomagnify in the food chain, leading to higher concentrations of these toxins in predatory fish species. This can have harmful effects on not only the fish themselves, but also on the birds or humans that consume them. Biomagnification is a process where the concentration of a toxin increases as it moves up the food chain.
Blood type is an example of a trait that's inherited by
A. incomplete dominance.
B. gender-specific alleles.
C. polygenic inheritance.
D. codominance.
Blood type is an example of a trait that's inherited by co-dominance.
CO-DOMINANCE:
Co-dominance is a type of inheritance pattern in which the alleles of a gene are neither dominant nor recessive over one another, hence, are simultaneously expressed. Co-dominance goes against the mendelian pattern of inheritance, which states that the dominant allele is expressed over the recessive allele. In co-dominance, both alleles are physically expressed. An example is blood type inheritance where alleles A and B are both expressed in an individual with AB genotype.Learn more about blood type: https://brainly.com/question/17058567?referrer=searchResults

e. coli and s. aureus and he forgets to decolorize with ethanol. what should his slide look like?
Both types of bacteria appear to be dark purple (stained with gentian violet), both will have a gram-positive appearance.
In the gram stain, two dyes are used: gentian violet and Fuschia pink, the two stains are separated by alcohol bleaching.
Alcohol bleaching (+ acetone) is the most important step in coloring. It must be fast in order to eliminate the rich lipid wall of the gram negative bacteria that has retained the staining, to then be colored by the pink Fuschia.
Beware, the abuse of alcohol will result in all Gram negative bacteria.
