The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.

Answers

Answer:

The correct answer is - b. inadequate mineralization in the osteoid.

Explanation:

Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.

This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.

if you are at 120X and the field diameter is 8.0 mm what is the field diameter if you go to 30X magnification?

Answers

Answer:

32 mm

Explanation:

The field of view is the total area visible through the microscope . The diameter of the field of view can be measured.

There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.

The relationship between field diameter and magnification is:

magnification of A * field diameter of A = magnification of B * field diameter of B

120X * 8 mm = 30X * B

B = 120X / 30X * 8 mm

B = 32 mm = 32000 μm

The field diameter of 30X magnification is 32 mm (32000 μm)

The question is incomplete. The complete question is :

In fruit flies, the recessive pr and cn mutations cause brown and bright-red eyes, respectively (wild-type flies have brick-red eyes). The double mutant pr cn combination has orange eyes.

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines ?

Answer:

prprcn+cn+ and pr+pr+cncn

Explanation:

Progeny is the offspring or descendants of any animal, plant, human or a species.

In the context, it is given that the cn mutation and recessive pr in the fruit flies makes brown and bright red color eyes. And the double mutant of pr and cn combination makes orange eyes. An oragne eye males is crossed with a female having a wild type eyes. Now for this, the F1 mother of the progeny F2 which results from the cross of two flies, the genotypes is " prprcn+cn+ and pr+pr+cncn. "

Answers

Answer:

light moths

Explanation:

yes their were most light color in most trees

Light moths was more common before the 19th century, when most trees were light in color.

What are the functions of light moths?

Insects, like moths, are drawn to bright lights because they make it difficult for them to navigate. It's a common sight, particularly in the summer: The lights, like lamps, were surrounded by moths and other insects.

Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.

No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:

Answers

Answer: Sterilization.

Explanation:

Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.

Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).

Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.

Examples of sterilization include physical methods and chemical methods. Physical methods include:

Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)

Chemical methods include a variety of chemicals in liquid and vapor form, for example:

Hydrogen peroxideChlorine dioxideOzone gasesEthylene oxidePropylene oxidePeracetic acid
