If a eukaryotic cell has 20 chromosomes and it undergoes meiosis, how many cells will result, and how many chromosomes will they contain

Answers

Answer 1
4 cells will result. Each cell will have 20 Chromatids which is half a chromosome. once sexual reproduction takes place, these 20 chromatids will match with those from the other parent cell to form chromosomes 
Answer 2

Upon undergoing meiosis the result will be that 4 cells are formed and each one will have 10 chromosomes in it as genetic material.

What is meiosis?

Meiosis is one of the two types of cell division in which a cell divides to form 4 daughter cells. The genetic content that is passed on to each daughter cell is half of that present in the parent. That is the reason for meiosis also to be called 'reductional division'.

The complete meiosis is accomplished in two stages: Meiosis I and Meiosis II. Meiosis I is similar to the mitotic division.

Think about the structure and function of your backbone. why do you think there are discs of cartilage between the bones in the vertebral column?

Answers

The capacity of the backbone is to secure the spinal line, yet it additionally needs to take into consideration developments, for example, twisting around or turning from side to side. The a wide range of fragments of bone consider this bowing or bending significantly more than a solitary bone stretching out from the neck to the coccyx could.

Final answer:

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?

Answers

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.

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.

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.

When animals consume a toxic material and it builds up in their bodies more quickly than it can be metabolized or excreted, it may harm them, as well as humans who consume them. What is this process called?

Biomagnification
Biological half life
Environmental persistence
Environmental stability

Answers

This is biomagnification (buildup of toxins in one organism).

Final answer:

Biomagnification is the term for toxic materials accumulating in animals and increasing in concentration up the food chain, impacting apex predators and potentially causing significant ecological harm.

Explanation:

The process by which toxic materials build up in the bodies of animals and become more concentrated at each level of the food chain is called biomagnification. This happens with toxins that are persistent in the environment and are poorly degradable and lipid-soluble, such that they accumulate in the fatty tissues of organisms. As an example, consider the case of DDT, a pesticide which exemplified the consequences of biomagnification, leading to detrimental effects on apex predators like the bald eagle, by causing their eggshells to become fragile and threatening their populations.

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

Answers

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 homeostasis

Thirst 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.
