Answer:
Chromosome, Gene, Allele
Explanation:
Chromosomes are structures of tightly wound-up DNA. Genes are sections of DNA that inherited. The gene is used to produce proteins and show outward characteristics. An Allele is an alternate version of a gene. You can have 2 or 3 different versions of the same gene.

Since Asha is a healthy woman in her fortles, she does not have Niemann Pick
disease type A. For this question, assume that she is a healthy person who is a
carrier. If Asha is a carrier of the allele for Niemann Pick disease type A, what is het
genotype?
Answer:
By the definition of "carrier," Asha does not exhibit any physical features (phenotype) of the Nieman-Pick disease, but she carries an allele for this disease. In order for this to be possible, Asha must carry a autosomal dominant allele for this gene to mask the effects of carrying an allele for the.

By the definition of "carrier," Asha does not exhibit any physical features (phenotype) of the Nieman-Pick disease, but she carries an allele for this disease.

Bessel's Star (61 Cygni) was the first star whose distance was calculated using the parallex method. The star is known to make an angle of 570 milliarcseconds between two opposite points of the Earth's orbit. Using this information, calculate the distance to the star.
Answer:
The parallax formula states that the distance to a star is equal to 1 divided by the parallax angle, p, where p is measured in arc-seconds, and d is parsecs.
d = 1/p
Explanation:
Parallax is a method of using two points of observation to measure the distance to an object by observing how it appears to move against a background. One way to understand parallax is to look at a nearby object and note its position against a wall. If you look with just one eye, then the other, the object will appear to move against the background.
Because your eyes are separated by several centimeters, each eye has a different perspective of where the object is relative to the background. The closer the object is, the more it appears to move relative to the background. This is true in astronomy as well, but on a much larger scale.
In astronomy, the distances to other stars is too great to measure using two objects on the Earth's surface. Lucky for us, the Earth itself moves. If we made two observations of the same star on opposite sides of the Earth's orbit, we would have a separation of 2 astronomical units, or AU. One AU is the average distance from the Sun to the Earth.
This is enough to get a noticeable angle, α, between the star's two apparent locations. In the image above, we can see that by cutting α in half, we get a right triangle where one leg is the distance between the sun and the other star. Lets let 1/2α=p. We can use tan p to find the distance to that star.
tan p = 1AU/p
Since the star will be very far away, we can make the assumption that
tan p is about equal to p. That simplifies our parallax formula to;
p = 1AU/d , or in other words, d = 1AU/p
Astronomical units are not the most convenient units to work with, though, so instead we define a parsec to be the distance to a star that shows 1 arc-second of parallax angle. Our formula then becomes;
d = 1/p parsecs
ANSWER:
!!Where p is measured in arc-seconds. 1 parsec is about 3.3 light years.!!

How do plasmodesmata affect the individuality of the cells?
Answer:
[tex]{\fcolorbox{blue}{black}{\blue{answer}}}[/tex]
Plasmodesmata play roles in both cellular communication and in molecule translocation. Plant cells must work together as part of a multicellular organism (the plant); in other words, the individual cells must work to benefit the common good. Therefore, communication between cells is crucial for plant survival.
Which of the following statements regarding the relationship of genes and enzymes is most accurate
Answer:
This question lacks options, the options are:
A) Enzymes and genes function cooperatively in the cell
B) genes code for enzyme production
C) Enzymes manufacture genes
D) Enzymes and genes are chemically similar
The answer is B
Explanation:
Genes are structural and functional heritable unit of DNA that carries instructions needed for the synthesis of a protein. In other words, a gene is a segment of DNA that encodes a useful product such as protein.
Enzymes are proteinous chemical substances i.e. they are proteins that serve as biological catalyst in living systems. Since enzymes are proteins, it means that they are encoded by genes. Hence, according to this question, the most accurate relationship between them is that GENES CODE FOR ENZYME PRODUCTION.

Why are niches important to
ecosystems?
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

Global warming is causing atmospheric CO2 levels to increase, which is expected to cause ocean acidification Which of the following is NOT a consequence of increased atmospheric CO2 levels?
a) decrease in the concentration of bicarbonate ions in the oceans
b) increase in the amount of carbonic acid formed in the oceans
c) decrease in the amount of calcium carbonate produced in the oceans
d) decrease in the concentration of carbonate ions in the oceans
e) increase in the concentration of hydrogen ions in the oceans
Answer:
This might not sound like much, but the pH scale is logarithmic, so this ... The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning ... track and forecast ocean acidification, warming and other important ocean
An increase in atmospheric CO2 levels does not cause a decrease in the concentration of bicarbonate ions in the oceans.
WHAT IS OCEAN ACIDIFICATION?
Ocean acidification is the decrement in pH level of the ocean due to the absorption of carbon dioxide (CO2). Carbon dioxide is a gas that reacts with water to form carbonic acid (H2CO3), which makes the water acidic or have a low pH.CONSEQUENCE OF CO2 ABSORPTION IN OCEANS:
An increased CO2 level in the atmosphere means that the rate at which the ocean will absorb the atmospheric gas will it increase. Since CO2 is said to make the ocean acidic, the following will likely occur to increase acidity of the ocean:
Increase in the amount of carbonic acid (H2CO3) formed in the oceansDecrease in the amount of calcium carbonate (CaCO3) produced in the oceansDecrease in the concentration of carbonate ions (CO32-) in the oceansIncrease in the concentration of hydrogen ions (H+) in the oceansN.B: Bicarbonate ion (HCO3-) causes acidity, hence, the decrease of bicarbonate ions cannot be a consequence of ocean acidification.
