Explanation:
Over 1,800 mutations have been described within the CFTR gene. These mutations can be readily detected using PCR and DNA sequencing technologies. Prenatal genetic testing is available to identify 'carriers', and thus detect the risk of CFTR-related disorders. If a pregnant mother was tested and tested negative for any known disease-causing CFTR mutations, can it be assumed that the child born will be wild-type with respect to the CFTR phenotype? Explain.
a. No. If the father is a carrier and passes along a mutant allele to the child, the child will develop cystic fibrosis.
b. It depends on the genotype of the father.
c. Yes. Since this is a recessive disorder, even if the father is a carrier, the mother will contribute a wt allele, ensuring the child is wt.
Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
22. Explain how emission or absorption spectrum can be used to identify the composition of objects in space
Answer:
Identifying elements in astronomical objects using their spectra. Measuring the spectrum of light from a star can tell astronomers what the star is made up of. Since each element emits or absorbs light only at a particular wavelength astronomers can identify what element are in the stars from the lines in their spectra.

High levels of LDL cholesterol in the bloodstream can lead to formation of "plaques" in the arteries. _________________________________ Facilitator
• What are the potential health consequences of coronary arteries being clogged by "plaques"?
• Name some specific foods that might lead to increased LDL cholesterol in the bloodstream.
• What do these foods contain that could cause this?
Answer:
The summary including its circumstances given has been listed below.
Explanation:
(a)
The development of plaques within the arteries shortens ones lumen down, thereby restricting blood supply and demanding further effort from the heart. The plaque could fully obstruct the arterial path if left unchecked, blocking the blood circulation to that portion of the brain where even the artery goes. There seems to be a condition that is life-threatening. When there has been a abundance of fats, cholesterol, calcium and several other substances throughout the body, plaque becomes produced. This same coronary artery fills every heart to pump blood. The blood supply to something like the cardiac muscles would be suppressed as well as the cardiac muscles wouldn't get adequate oxygen whether there is plaque forming within this artery. This should lead to heart disease that can cause damage again for human.(b)
These are some of the five main lipid classes is LDL, or low-density lipoprotein. It is deemed undesirable although it contributes to cholesterol build-up throughout the arteries. In animal products like poultry, including bacon, fatty acids are often included. Other types of animal fats include milk as well as dairy products, including such butter, etc. Farm products such as almond and almond oil, palm as well as palms kernel oil, chips as well as other unhealthy fats are therefore high in saturated fats as well as improve LDL levity throughout blood.(c)
There are a variety of saturated unhealthy fats elsewhere in this-mentioned food products that increase the amount of LDL throughout the blood.Which of the following organelles can change shape, can move quickly around the cell, and is found in both plant and animal cells?

B) because a drought goes without water and rain deals with hydrosphere atmosphere and geosphere
Plants are called “producers” because they make their own food by gathering energy from the Sun. Plant populations compete with each other for light, nutrients, and space. One survival pressure comes from “consumers” who eat the plants for food.
Think of an example of a plant that has evolved a mechanism for protecting itself against consumers. Describe the mechanism. Describe how a consumer might overcome this mechanism!
Answer:
one example would be "Acacia Collinsii."

Which statement best supports the RNA world hypothesis?
DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins.
Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code.
Simpler self-replicating organic molecules preceded RNA and contain genetic information.
The absence of oxygen in Earth's early atmosphere allowed for proteins to catalyze the production of new RNA molecules.
Answer:
the first one

Why are paper clips attracted to magnets ?
A. They contain silver
B. They contain aluminum
C. They contain Tin
D. They contain iron
Answer: D
Explanation: Paper clips are attracted to magnets because they contain iron.
PLz mark brainliest:)
Answer: Paperclips are generally made of steel, a major component of which is iron. Iron is a ferromagnetic material — in other words, it becomes a magnet when in the presence of an external magnetic field. So when you bring a magnet close to a paperclip, the iron in the paperclip becomes magnetized, and they leap together!

The trees and cities are just WAY too small and far away for us to see if we were in outer space.

Thank You!!
Answer:
The air above land is warmed more quickly than air above water. Warm air expands and rises, creating an area of low pressure; cold air is dense and sinks, creating an area of high pressure.
Explanation:
The structure of a cell is most closely related to which of the following
A. The size of the cell
B. the function of the cell
C. The number of mitochondria in the cell
D. Whether the cell is living or not
Cells assume different structures primarily on the basis of the function with which they are associated. Thus, the correct option is B.
The number of mitochondria or the size of the cell do not have any influence on the structure of the cell.
On the basis of the function, there are different features that are added or modified in the cell.
For instance, the cells in the intestine are primarily involved in absorption and hence, they have a special structure called villi on their apical surface for maximal absorption.
Similarly, RBCs have a disc shape for maximum surface area for fulfilling its function of oxygen absorption and diffusion.

9. Which is the pathway of oxygen from lungs into the body tissues?
a. alveoliblood vessels--tissues- red blood cells
b. alveoli red blood cells-blood vessels--tissues
c. red blood cells alveoll--blood vessels-tissues
d: tissues-- red blood cells- alveoli
Answer:
The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).
Explanation:
The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:
O₂ from the air reaches the lungs. In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated. O₂ in the red blood cells travels through the blood vessels. The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.
The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.
The cross of these two faces produces an offspring. If the alleles for color show incomplete dominance and the alleles for eye shape are codominant, what will the offspring look like?
a yellow smiley face with two star eyes
a yellow smiley face with one circle eye and one star eye
an orange smiley face with two circle eyes
an orange smiley face with one circle eye and one star eye
The offspring will have a yellow smiley face with one circle eye and one star eye.
What is codominance?When a hete---rozygous genotype generates an intermediate phenotype that combines the two homozygous traits, incomplete dominance results. When both alleles have an impact on the phenotype of the heterozygous person, codominance occurs.
Depending on the genetic composition of the parents, the baby may have two star eyes, two circle eyes, or one circle eye and one star eye. Hence, the offspring will have a yellow smiley face with one circle eye and one star eye.
