Explanation:
In eukaryotic cells, pre-mRNA has to undergo 3 stages of RNA processing before being transported into the cytosol. Specifically during RNA Splicing, small nuclear RNAs (snRNAs), small nuclear ribonucleoproteins (snRNPs) and other proteins form a spliceosome which excises introns and splice together exons. Introns are considered junk material and does not stay with the mRNA.
The answer is Introns. (D)
Answer:
d. introns

What happens when a dentist and a candymaker meet? Together,
William Morrison, a dentist, and John C. Wharton, a handymaker,

the young and old. The two sold their cotton candy at the Paris
Exposition in 1900 and the St. Louis World's Fair in 1904 for 25¢ a box,
and the rest is history. The fascinating story of how cotton candy
found its place in American culture is as sweet as the treat itself.

Clear-winged dragonflies live longer and can reproduce
many more times than yellow-winged dragonflies.
How is this population of dragonflies most likely to change as a result of this
difference?
Answer:
Yellow-winged dragonflies will most likely decrease and eventually die out on account of being easily spotted by predators.
Answer: Clear-winged dragonflies will become more common over time.
Which organisms perform photosynthesis in the ocean?
Answer:
Bioplaykton
Explanation:
how is the hydrosphere connected to the lithosphere
Answer:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.

Which scientific area has the most influence in shaping modern classification methods?
Answer: The answer is " evolution". Evolution is a major force in shaping modern classification methods. Evolution is the adjustment in the qualities of an animal categories more than a few ages and depends on the procedure of common determination.
The scientific field which has had the greatest influence on shaping modern classification methods is Evolution.
What is Evolution?Evolution is concerned with the sequence of changes which occur in organisms as they transform from their ancient forms to their modern forms.
It is the change in the genetic characteristics of a biological population over successive generations. These characteristics are manifestations of genes passed from parents to offspring during reproduction.
The three main types of Evolution are:
1. Divergent Evolution
2. Convergent Evolution
3. Parallel Evolution
Thus, the scientific field which has had the greatest influence on shaping modern classification methods is Evolution.

. Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in
bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them
defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.

What events in sexual reproduction contribute to genetic variation in a population that contributed to evolution
of the species on our planet? Explain.
Answer:
Meiosis is the first step in sexual reproduction during which crossing over and recombination develops new combinations of genes on chromosomes. When gametes are produced they under go random fertilization and offsprings with great genetic variations are produced.
This leads to evolution of species on the planet.

Which body sense (choose only 1) do you think is most important? Explain why and provide at least 2 examples. (Your essay must be 1-2 paragraphs).
Answer:
I believe sight is the most important body sense. Our eyes are able to protect us from danger and allows us to complete many day to day functions. Without our sight, we could be much more easily placed into harms way. Our eyes take over to ensure we are prepared for anything we may encounter.

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.
Answer:
F1) 100% bbRr, red flowered plants.
Explanation:
Available data:
flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).
According to the first cross, we might establish the following genotypes:
1st Cross: blue-flowered plant x red-flowered plant
Parentals) BBrr x bbRR
Gametes) Br, Br, Br, Br bR, bR, bR, bR
F1) 100% BbRr, yellow plants
Parentals) BbRr x BbRr
Gametes) BR, Br, bR, br
BR, Br, bR, br
Punnett square) BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
F2) 9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR
3/16 blue ------> 1/16 BBrr + 2/16 Bbrr
3/16 red---------> 1/16 bbRR + 2/16 bbRr
1/16 mauve ----> 1/16 bbrr
So,
Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrrAccording to these genotypes, the second cross would be like following,
2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.
Parentals) bbRR x bbrr
Phenotype) Red Mauve
Gametes) bR, bR, bR, bR br, br, br, br
Punnett square) bR bR bR bR
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
F1) 100% bbRr, red flowered plants.
Do cell membranes contain proteins, but phospholipids and cholesterol
Answer:
In addition to lipids, membranes are loaded with proteins. In fact, proteins account for roughly half the mass of most cellular membranes. Many of these proteins are embedded into the membrane and stick out on both sides; these are called transmembrane proteins.The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable.In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. ... Because the interior of the phospholipid bilayer is occupied byExplanation:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
