True or false? Today people with very short sight can wear glasses with thinner lenses because the lenses do not need to be so powerful

Answers

Answer 1

Answer:

The statement "Today people with very short sight can wear glasses with thinner lenses because the lenses do not need to be so powerful" is true.

Is the statement true or false?

Yes, this statement is true. People with very short sight (myopia) require corrective lenses that are concave in shape to help focus distant objects properly on the retina. The power of the lens is determined by the degree of myopia – the more nearsighted a person is, the stronger the prescription needed.

Advancements in lens manufacturing and design have allowed for the creation of high-index lenses. These lenses are able to bend light more efficiently than traditional lenses, meaning that they can achieve the required optical correction with less material. As a result, people with high prescriptions, whether for nearsightedness or other vision issues, can wear glasses with thinner and lighter lenses while maintaining the necessary corrective power. This has greatly improved comfort and aesthetics for individuals who require strong corrective lenses.

Answers

Answer:

Genetically identical

Explanation:

Mitosis is a simpler cell division as compared to the meiosis cell division. Here , the genetic material on the chromosome replicates itself and produces exactly the same set of chromosomes which after Cytokines lead to formation of similar cells.

This kind of cell division is common is non sex cells which are required to replicate fast and in large numbers to form body organs. These cells play an important role in development of embryos.

Which of these best demonstrates mutualism between certain types of bacteria and humans

Answers

Mutualisam between types of Bateria and Humans

Bacteria and the human both get benefit from each other and this relation is mutualism. Bacteria stay inside nose, mouth, intestines, and many more areas of the body surface. They help human by giving response to pathogenic bacteria for protection of immune system.

They metabolize nutrients, vitamin production and wastes process in human’s digestive system. On the other hand, human provides them place to live. These above best demonstrates mutualism between bateria and humans.

I cannot find the propositions if it is a MCQ, so I will tell what a bacterial mutualism is:

Mutualism is an exchange between species (two or more) in which the mixed organisms profit from this exchange. Unlike commensalism, the associated species adapt, because the modification of one can affect the survival and reproduction of the affiliated species.

Many mutualistic bacteria live and develop in us, for example, the intestinal flora synthesizes vitamin K, a vitamin that is necessary for the absorption of our food. This same intestinal flora also hinders the proliferation of pathogenic bacteria as well as that of commensal bacteria potentially dangerous.

In which of the following situations will the ball have the greatest acceleration?O
A golf ball with a mass of 0.045 kg is struck with a force of 1 N.
A baseball with a mass of 0.142 kg is hit with a force of of 5 N.
o
Asoccer ball with a mass of 0.45 kg is kicked with a force of 20 N.
o
A bowling ball with a mass of 7.2 kg is thrown with a force of 60 N.

Answers

The ball with the greatest acceleration is the soccer ball with a mass of 0.45 kg and kicked with a force of 20 N, which has an acceleration $44.4 m/s^2$

How to determine which has the greatest acceleration?

To calculate the acceleration of each ball, we can use the following equation:

acceleration = force / mass

Golf ball:

acceleration = $1 N / 0.045 kg = 22.2 m/s^2$

Baseball:

acceleration = $5 N / 0.142 kg = 35.2 m/s^2$

Soccer ball:

acceleration = $20 N / 0.45 kg = 44.4 m/s^2$

Bowling ball:

acceleration = $60 N / 7.2 kg = 8.3 m/s^2$

Therefore, the ball with the greatest acceleration is the soccer ball, which has an acceleration of $44.4 m/s^2$ .

If you cut your finger, which organ systems will be involved in the healing process? How do they work together?

Answers

Answer:

The circulatory system stops the bleeding with platelets, which provide a seal so that healing can begin. The immune system kills off any bacteria that get into the wound and helps to eat away any debris so healing can begin. The nervous system responds to the cut with pain, telling me that an injury occurred.

Explanation:

This is the answer from Edmentum

Answer:

Platelets from the circulatory system halt the bleeding, creating a seal that allows healing to start. In order for healing to start, the immune system eliminates any germs that enter the wound and aids in the digestion of any waste. The cut causes my neurological system to produce pain, alerting me to the fact that I've been hurt.
