Answers
Ingesting cellular debris occurs in a process called: Phagocytosis.
What is Phagocytosis?Phagocytosis is a crucial biological process in which cells engulf other cells or cellular debris to eliminate harmful elements from the body. The process helps in removing the debris or foreign invaders from the body.
The mechanism is often employed by immune cells that act as the first line of defense in our body. Examples of such cells include macrophages, neutrophils, and dendritic cells.
These immune cells act by consuming harmful or foreign substances such as bacteria, viruses, and even dead cells that can otherwise cause damage to the host organism. When these cells are engulfed by immune cells, they are destroyed and broken down into smaller components which can be easily eliminated from the body by the excretory system.

An old biological notion from the 19th century is called blending inheritance. According to the hypothesis, a kid receives a trait by averaging the values of its parents for that trait.
As an illustration, pink-flowered children might result from breeding a red flower variation with a white variant of the same species. Inheritance was blended according to Charles Darwin's idea of inheritance via pangenesis, which included contributions to egg or sperm from every organ of the body.
Fleeming Jenkin attacked Darwin's theory of natural selection because of his dependence on this mechanism, arguing that blending inheritance would average out any unexpected advantageous property before selection had a chance to work.
The widespread acceptance of particulate inheritance led to the rejection of blending inheritance.

Jenny is a cancer patient and has had several rounds of chemotherapy. Her blood is always drawn each time she arrives at the clinic for her chemotherapy. They are checking her white blood cell levels. She is told today her blood shows her neutrophils to be at 2,200 per microliter.
1.) Based on the level of neutrophils what do you think the recommendation for chemotherapy will be for today? You must defend your answer.
2.) With a neutrophil count at this level, what would the patient be susceptible to and why?
Answers
Answer:
HelloExplanation:
Answer:
1.
The neutrophil count is an important measure of a patient's immune system function. Neutrophils are a type of white blood cell that play a critical role in fighting off infections. A normal neutrophil count ranges between 1500 to 8000 per microliter.
A neutrophil count of 2200 per microliter is within the normal range, although it is on the lower end. It is likely that Jenny's healthcare team will proceed with the chemotherapy treatment as scheduled, assuming that her neutrophil count has been stable or improving. However, her healthcare team will closely monitor her neutrophil count during and after the chemotherapy treatment to ensure that it does not drop to dangerously low levels.
2.
With a neutrophil count at this level, the patient may be susceptible to infections. Neutrophils are the body's first line of defense against bacteria and other harmful pathogens, and a low neutrophil count can make it difficult for the body to fight off infections.
If a patient's neutrophil count drops below 1000 per microliter, they are considered to be at a higher risk of developing infections. This is because the immune system may not be able to fight off pathogens effectively, increasing the likelihood of infection. In severe cases, this can lead to sepsis, a life-threatening condition that occurs when the body's response to infection causes tissue damage and organ failure.
Therefore, it is important for patients with low neutrophil counts to take extra precautions to avoid exposure to infections. This may include avoiding contact with sick individuals, practicing good hand hygiene, and avoiding activities that may increase the risk of infection. Additionally, patients with low neutrophil counts may be prescribed medications or receive other treatments to help boost their immune system and reduce the risk of infections.

The Griffith experiment marked a turning point in the understanding of genetic material.
What did the Griffith experiment show?
Frederick Griffith made a significant discovery in the 1920s. He was researching two separate bacterial strains known as the R (rough) strain and the S (smooth) strain. He gave the two strains to mice by injection. The R strain did not kill the (virulent) mice, while the S strain did (non-virulent). Griffith also administered heat-killed S-strain bacteria to mice. The mice were unharmed by the germs, as was to be expected. However, when live R-strain bacteria were injected along with dead S-strain germs, the mice perished. Griffith's observations led him to the conclusion that something from the deceased S strain had been passed to the R strain, rendering it deadly. Since something was "transforming" the germs from one strain into another, he named this process metamorphosis.Learn more about the Griffith's Experiment with the help of the given link:

Answers
Answer:
Homeostasis
Explanation:
The body is maintaining a steady blood pH of 7.2 is an example of maintaining homeostasis. The correct option is A.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical conditions maintained by living systems.
This is the state of the organism's optimal functioning, which includes many variables, encompassing the body temperature and fluid balance, being kept within certain pre-set limits.
The maintenance of blood pH within normal range of 7.35-7.45, renowned as acid-base homeostasis, is a complex synergy involving three organs (lungs, kidneys, and brain) as well as chemical buffers in blood and blood cells (erythrocytes).
Body fluid pH is strongly required by buffering systems, efflux across the plasma membrane, and acid excretion.
Carbon dioxide is used by the pulmonary system to adjust pH; upon expiration, carbon dioxide is expelled into the environment.
Thus, the correct option is A.

a) The TOUR de France is happening on the 26 th June 2021 from BREST to MÜR DE BRETAGNE. Mark cycles from Brest to MŨR DE BRETAGNE and Jay cycles to the opposite direction. Knowing that the distance between BREST and MÜR DE BRETAGNE is approximately 131Km and that both cyclists start cycling towards each other at the same time. Assuming that Mark cycles twice as fast as Jay does. If both cyclists meet one and half hour later, then at what average speed is each one of them traveling?
Answers
Jay is cycling at an average speed of 29.11 km/h and Mark is cycling at an average speed of 58.22 km/h.
The average speed of each of the cyclists will be different. Let’s use the formula, speed = distance/time to find their average speed.
The total distance between Brest and Mũr de Bretagne is approximately 131km.If both cyclists start cycling towards each other at the same time and meet one and a half hours later, their combined distance covered will be the total distance.
That is,
131 km = Mark’s distance + Jay’s distance
Let’s use the variable x to represent Jay’s speed.
Therefore,Mark’s speed = 2x km/h
Using the formula speed = distance/time, we can derive the following equations:
Mark’s distance = Mark’s speed × timeJay’s distance = Jay’s speed × time
Total distance = Mark’s distance + Jay’s distanceMark’s distance + Jay’s distance = 131 kmMark’s speed = 2x km/h
Time = 1.5 hours
Substituting the above into the equation:
Mark’s distance + Jay’s distance = Total distance(2x km/h) × 1.5h + (x km/h) × 1.5h = 131 km(3x km) + (1.5x km) = 131 km4.5x km = 131 kmX = 29.11 km/h
Jay’s speed = 29.11 km/h
Mark’s speed = 2x km/h= 2 × 29.11 km/h
= 58.22 km/h

A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide.

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.[3][4][5] The included extinctions span numerous families of plants[6] and animals, including mammals, birds, reptiles, amphibians, fishes and invertebrates. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, or no one has yet discovered their extinction. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates.

Porcupines have evolved to turn their backs on predators and elevate their quills to make them more visible to their faces. Due of their delicate noses, many pet dogs have fell for this prank and gotten too close. The porcupine's physical modifications enable it to live in its environment.
