How might we determine if albinism is an inherited or acquired trait?
Answer:
In all types of OCA and some types of OA, albinism is passed on in an autosomal recessive inheritance pattern. This means a child or something else has to get 2 copies of the gene that causes albinism
Which of the following individuals is true-breeding for all traits? A. RrYY B. RRYy C. RRYY D. RrYy ellus Corporation. All Rights Reserved.
The true breeding individual for all traits is RRYY.
What is True breeding ?A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring of many generations. This means that the parents are homozygous for every trait.
Since RRYY is homozygous for all traits, it will be a true breeding organism if crossed over with another RRYY organism. This is because all the off-springs produced from this cross will also be RRYY that is purebred.

For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. 4 1 5 0 2
Answer:
For each glucose that enters glycolysis, 2 acetyl CoA enter the citric acid cycle.
Explanation:
SYNTHESIS OF 2Acetyl CoA -:
The glucose is transformed into 2pyruvate (6 carbon molecules are converted into 2 -3 carbon molecules) during glycolysis. In both aerobic and anaerobic respiration, glycolysis occurs frequently. This process takes place in the cytoplasm (it does not require oxygen or mitochondria), but if both oxygen and mitochondria are present, two molecules of pyruvate join mitochondria and prepare for citric acid cycle.
Until entering this, the molecules go through a mechanism known as the linked (connects glycolysis with citric acid cycle) reaction, in which the pyruvate molecule is transformed into 2 acetyl CoA (meaning 3 carbon molecules are converted into 2 carbon molecules) and a carbon molecule is released in the form of [tex]2CO_2[/tex] (waste product).
2NAD+ and NADH are synthesized in the linked reaction, implying that reducing power is produced. It means that electrons from pyruvate are released in the form of hydrogen, which 2NAD+ accepts and reduces to form 2 NADH.
[tex]Glucose[/tex] → [tex]2pyruvate[/tex] → [tex]2Acetyl CoA[/tex]
Linked reaction is also known as oxidative -dicarboxylation.
Hence, 2 Acetyl CoA is required to enter citric acid cycle.
Why might a speaker choose NOT to use contractions in a formal speech?
A. Contractions are too short.
B. Contractions are rude.
C. Contractions are informal.
D. Contractions are improper.
Answer:
The answer is C
Explanation:
I just took the quiz :)
A speaker might choose not to use contractions in a formal speech because contractions are informal. Thus, the correct option is C.
What is a Formal speech?A formal speech may be defined as a form of speech that is utilized in authorized and official workplaces. It does not illustrate personal background.
Contraction involves the feelings of pressure, stress, or shrinkage of actions. Thus, all such properties come under an informal type of speech where the personal background is determined.
Therefore, a speaker might choose not to use contractions in a formal speech because contractions are informal. Thus, the correct option is C.

3. Which type(s) of cells have genetic material that is contained in a nucleus?
A. bacterial
B. plants only
C. animals only
D. both plant and animal cells
Answer:
D. Both plant and animal cells
Explanation:
The explanation is that animal and plant cells are eukaryotic cells which means they have a nucleus which contains and protects the genetic material. Bacteria is a prokaryotic cell which means it does have genetic material but doesn't have a nucleus.

Why are Wind Turbines being moved offshore?
Answer:
Wind turbines are being moved offshore because the wind comes at the right time: Offshore winds are usually higher throughout the day, allowing for more reliable and productive electricity output when market demand is highest. The majority of land-based wind resources are more efficient at night when demand for electricity is smaller.

1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?
Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

How could you use the treated wastewater to recharge the aquifer?
Answer:
QUESTION:
How could you use the treated wastewater to recharge the aquifer?
ANSWER:
Treated wastewater could be used to recharge the local aquifer by discharging the treated water into an area with permeable sediments that overlies the aquifer. The treated wastewater would flow through the permeable sediments and into the aquifer, from which it could be pumped again for use in homes and businesses.

Explanation:
Vacuoles are cellular organelles that are found in all plant and fungal cells. In plant cells, vacuoles tend to store large amounts of water, so they can push outward on cell walls and help keep plants upright. In fungal cells, vacuoles often store materials that are toxic to the cell.
According to the above information, how do vacuoles help fungal cells maintain homeostasis?
A.
by storing large quantities of water
B.
by allowing the cells to get rid of waste
C.
by producing more cellular organelles

Answer:
D. by helping the cells extract energy from food
Explanation:
Fungi are decomposers so they normally need some sort of food to grow. To get the energy to grow, they extract it from the food. Fungi will get their energy from dead animals, dead plants, etc.

Is DNA replication always a foolproof process? Explain your answer.
Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.
Explanation:
No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.
Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.
Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.
Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?
Answer:
The rate of transpiration would decrease
Explanation:
the petroleum jelly would block the stomata of the leaves resulting in decreased transpiration rates
Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.
What is transpiration?Transpiration exists the procedure of water movement via a plant and its evaporation from aerial parts, such as leaves, stems, and flowers. Water exists essential for plants but only a small amount of water brought up by the roots is utilized for growth and metabolism. The remaining 97–99.5% exists lost by transpiration. An example of transpiration exists when a plant absorbs water in its roots.
Hence, Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Answer:
Explanation:
Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.
