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.
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.
Here is a pedigree for colorblind (H)
What is fred's genotype?
Answer:
[tex]x^{h} y[/tex]
Explanation:
Fred has inherited the colorblind trait from his mother. We know this because his spot on the pedigree is filled in. Because he is a male his genotype must be some variation of xy and because he is colorblind he must have the recessive "h" on his x chromosome. So his genotype (genetic type) is [tex]x^{h} y[/tex]

How do mutations affect natural selection
Answer:
The idea of natural selection would in theory be affected by mutations because natural selection invloves a species/animal only surviving by having a certain trait. Over time, all of the animals/species would have this trait through elimination partnered with reproduction. A mutation may begin this cycle by giving an animal the ability to have an advantage over its fellow species.

1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black

Mechanical waves react to different mediums in different ways. Some mechanical waves are _________________ through a medium, meaning they pass through the medium. The way in which waves are transmitted depends upon the type of material. In ________________, mechanical waves travel rapidly, because the molecules are ___________________ packed. In liquids and air, however, mechanical waves travel more _________________, because the molecules are spread farther apart.Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it ______________ off the medium and then travels in a ______________ direction. ______________ is an application that uses sound wave reflection to determine how deep water is. A third way mechanical waves react to a medium is _______________. When a mechanical wave is absorbed, it remains __________________ a medium and is not transmitted to another medium.
Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.
The fill in the blanks will be filled with TRANSMITTED, SOLIDS, DENSELY, SLOWLY, BOUNCES, DIFFERENT, SONAR, ABSORPTION, WITHIN
Mechanical waves:react to distinct mediums in various ways. Some mechanical waves are TRANSMITTED via a medium, meaning they pass via the medium.

If there will be changes on trophic levels, what will be the effects on the ecosystem?
Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.

hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format
Answer:
If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Explanation:
Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.
Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"
A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Answer:
A. If either parent mouse passes a dominant allele, the offspring will have black fur.
Explanation:
Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33
Which device works similar to the way kidneys work in the human body? HELP IM BEING TIMED!!!
Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

You might then also realize that the new method, at least on paper, may have additional applications. ... which makes the technology attractive to yet more scientists.
Explanation:
Hoped I helped you out please mark me brainliest!!!
With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.
What is a microscope?A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.
In most cases, the light is focused on the sample by passing it through a condenser.
After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.
The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.
Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.
