Osteogenesis imperfecta is tested for OI so if a family member has OI then a health care provider can test the DNA of the fetus for the presence of an OI mutation.
Answer:
Well I have osteogenesis imperfecta and I only got tested because I had broken 3 bones and I would just barely fall and it really didn’t make sense. So my mom demanded test

Biochemistry involves the production and degradation of biological molecules such as nucleic acids, proteins, lipids, carbohydrates, and vitamins. Changes in the production or degradation of these important molecules can cause disorders and diseases in humans. For each of the human disorders and diseases listed below, indicate whether it is caused by a change in: (A) nucleic acids (for example: DNA or RNA); (B) amino acids/proteins; (C) lipids (for example: cholesterol or triglycerides); (D) carbohydrates/sugars; or (E) vitamins. Provide only one (1) answer for each disease.
Answer:
Disorders are present below.
Explanation:
Degradation of nucleic acids causes Lesch-Nyhan syndrome and mitochondrial depletion syndromes in human body, degradation of proteins causes phenylketonuria and tyrosinemia diseases in humans, degradation of lipids causes Gaucher disease and Tay-Sachs disease. Due to these diseases of lipids, we have not enough enzymes to break down lipids, degradation of carbohydrates leads to diabetic ketoacidosis, hyperosmolar coma and hypoglycemia, and degradation of vitamins causes anemia and scurvy diseases in the body.

The process of natural selection is seen most quickly in organisms that can reproduce many generations in the shortest amount of time. Based upon this information, which type of organism would exhibit the most rapid rate of evolution?
1.bacteria
2.fruit flies
3.finches
4.humans
Answer:
2
Explanation:
one time within 2 days my house was filled with fruit flies
Answer:
Bacteria
Explanation:
Bacteria reproduce most quickly . Fruit flies can go from the egg to sexual maturity in 3 weeks while bacteria can reproduce once they are "born" and can do so multiple times a day, while fruit flies can reproduce if mature once every day about.
Finches and humans obviously have much slower rates of reproduction.
You have identified a new, recessively inherited trait in dogs: floppy ears. To determine if the gene for Floppy Ears is X-linked or not, you should:
Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
Imagine researchers following up on seeley's study brought some flat periwinkles appledore island into the lab to test for heritability. What results could they observe that would support the hypothesis that shell thickness is heritable in these snails?
Answer:
If thick-shelled snails have thick-shelled offspring and thin-shelled snails have thin-shelled offspring then this is good evidence that shell thickness is heritable.
Explanation:
Inheritance is a natural mechanism by which genetic information contained in the DNA sequence is passed from parents to offspring. Moreover, heritability is a measure of the genetic influence on the variation in a particular phenotypic trait (e.g., height, eye color, etc.) between individuals in a population. The values of heritability for a particular phenotypic trait range from zero (when all variation in a population comes from environmental factors and therefore is not heritable) to one (when all variation in a population comes from genetic factors and therefore is heritable). For example, in this case, if parental snails always have offspring with the same phenotype for the trait ‘shell thickness’, it would indicate that the heritability for this trait is equal to one, thereby evidencing that all of the variability for the trait 'shell thickness' comes from genetic differences.
How can you tell from a food web which organisms will have the greatest biomass?
Answer:
How can you tell from a food web which organisms will have the greatest biomass?
The tropic level contains the greatest biomass in most ecosystems is producers. This occurs because producers get their energy from the sun, the sun is the most available resource, so there are the most at that level.

how many chromosomes in the dna?
1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
3. Which statement describes a difference between
the nitrogen and carbon cycles?
a. The carbon cycle involves only plants.
Ob. The nitrogen cycle requires a process
called nitrogen fixation that is carried out by
certain bacteria.
O c. The carbon cycle requires freezing
temperatures.
d. The nitrogen cycle occurs entirely in
the ocean.
Answer:
a.
Explanation:
The carbon cycle involves only plants. The nitrogen cycle requires a process called fixation, which makes the nitrogen more usable for living organisms. The carbon cycle requires that temperatures be above 27 °C (80 °F).
HOPE IT HELPS

The statement that best describes a difference between the nitrogen and carbon cycles is the nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
What are the main differences between the nitrogen and carbon cycles?The main difference between nitrogen cycle and carbon cycle is that nitrogen cycle describes the conversion of nitrogen into multiple chemical forms and its movement between the different ecosystems. Whereas the carbon cycle describes the movement of carbon and its multiple chemical forms between the atmosphere, lithosphere and hydrosphere.
Microbes are involved in the nitrogen cycle process. Both plants and animals participate in the carbon cycle.
Thus, the statement that best describes a difference between the nitrogen and carbon cycles is option (b).

Strong contrasts in texture have what effect on a monochromatic design?
Answer:
It prevents monotony
Explanation:
Strong contrasts in texture have a primary effect on monochromatic design by ensuring it’s more eye catching and not too plain.
Contrasts is a term used to describe the display of an objects dissimilar sides. A monochromatic light is known to have just one color and the strong contrasting texture however makes it possible for it to have different color differences thereby preventing monotony.

According to the Big Bang theory, what happens if you reverse the galaxy motion and go back in time?
A. Everything would become condensed into one dense point
B. Some things would remain the same, while others go back
C. Everything would be the same as it is today.
D. You would find everything in a large cloud of cold isolated gas
According to the Big Bang theory, if you reverse the galaxy motion and go back in time A. Everything would become condensed into one dense point.
The Big Bang Theory simply explains how the universe was formed from a large explosion. According to the Big Bang theory, the universe was formed as a result of the explosion of particles.
The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. This is also called the Big Crunch. This will lead to the recollapse of the universe.
In this case, the cosmic scale also reaches zero. Then, everything would become condensed into one dense point.
