An animal leaves its footprint in wet mud, and later, when the mud dries, the footprint can be filled with plaster. When the plaster hardens, it has
same shape as the foot of the animal. The plaster cast could then be used to make new footprints in soft mud identical to those made by the animal. The
process of using the plaster cast to make new footprints most accurately models
translation of mRNA codons to form a protein.
transcription of mRNA from the original DNA code.
insertion of nucleotides into the mRNA codons
deletion of nucleotides from the tRNA anticodons.
Answer:
The process of using the plaster cast to make new footprints most accurately models transcription of mRNA from the original DNA code
Explanation:
Transcription is a process in protein synthesis that takes place in the nucleus. During transcription, the DNA of a gene is used as a template to make an RNA molecule. In the process, nucleotide bases which are complementary to those found in the DNA molecule pairs with the DNA bases in a process called complementary base-pairing. However, Uracil is the nucleotide base that binds to adenine in the mRNA instead of thymine. An enzyme called RNA polymerase II catalyzes the formation of a mRNA molecule. Three steps are involved in transcription:
Initiation- is the beginning of the transcription process when RNA polymerase binds to DNA.
Elongation- addition of nucleotides to the RNA strand.
Termination- is the end of the process whereby RNA strand detaches from DNA template. The resulting mRNA is a single-stranded copy of the gene.
It models the transcription of mRNA from the original DNA code.
The process of using the plaster cast to make new footprints most accurately models the transcription of mRNA from the original DNA code because both have exactly the same type of materials.
Transcription is the process in which the information present in a strand of DNA is copied into a new molecule of messenger RNA which serve as a blueprints for protein synthesis during the process of translation. The mRNA has all the information that is present in the original DNA so we can conclude that it models the transcription of mRNA from the original DNA code.

While studying the pollination patterns of bees, Marsha noticed that there were flowers that the bees in her area seemed to visit more frequently than others. The following table shows the flowers that 100 bees visited during a specific time period.
Flower Flower Color Number of Bees
sunflower yellow 32
daisy white 50
petunia purple 18
Marsha claims that the bees frequented the daisies the most because they are attracted to the color of the flower.
What is a reasonable alternate conclusion that can be drawn from Marsha's data?
a. Bees frequented the daisies the most because bees are unable see the color white.
b. Bees frequented the daisies the most because daisy pollen has an odor that is attractive to bees.
c. Bees frequented the daisies the most because they are most attracted to the color yellow.
d. All of these
Answer:
B
Explanation:
The only reasonable alternate conclusion that can be drawn from Masha's data is that the bees frequented the daisies the most because daisy pollen has an odor that is attractive to bees.
The conclusion is the only one that suggested an alternate reason that is compatible with the trend observed in the data.
Concluding that the bees frequented the daisies because they are unable to see the color white is erroneous because the bees could not have visited the daisies without the ability to see color white. If the bees were also most attracted to the color yellow, they should have visited the sunflower the most.
The correct option is B.
Answer:
B. Bees frequented the daisies the most because daisy pollen has an odor that is attractive to bees.
Explanation:
Scientists have differing opinions and interpretations when it comes to producing results for experiments. This creates the variety in science that springs up new investigations and experiments.
Marsha claimed that bees frequented the daisies because they are attracted to the color of the flower. An alternate explanation for why bees frequented daisies could be because daisy pollen has an odor that is attractive to bees.
Since daisies are white, it does not make sense to say that bees cannot see the color white. The explanation that bees frequented the daisies the most because they prefer the color yellow also is not reasonable because they would likely have visited the sunflowers the most if this were the case.

Planting trees reduces destruction to homes and crops by serving as ___ during typhoons and storms.
a. Shelter
b. Income
c. Feltilizers
d. Windbreakers
Answer:
Windbreakers
Explanation:
Income and fertilizers have nothing to do with it, so those are not it. Then there are shelter and windbreakers. It kind of acts as a shelter, but mainly it protects crops and homes by acting as a windbreaker. If it was shelter, that would mean that the crops would mainly be planted under the trees to reduce damage from storms and typhoons. Therefore, it is D) Windbreakers.

Answer:
1182
Explanation:
From the information given:
Number of present genes = 4380
the total no. of protein-encoding = 4290
Total no. of base pairs = 5175720
The percentage fraction of genes encoding the protein is;
total no of protein-encoding gene/total no of present genes
[tex]\mathbf{\dfrac{4290}{4380} = 0.9795}[/tex]
= 97.95%
The average number of base pairs per protein-coding gene is;

2. Honey Bees may be headed for extinction.
Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)
Answer:
Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.
Answer:
honey bees Extinction types are parasites ,habitat loss ,and cell phones. but there two main types of parasites that are harming the honeybees are Vero mites and tracheal

In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. The complete cell cycle requires 24 hours. Match the average duration to the appropriate cell cycle stage in these cells. M phase prophase metaphase telophase 4.8 hours 14.4 minutes 2.4 hours 36 minutes
Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

This scientist looked at cork and used the term "cells" to describe what he saw *
Answer:
Robert Hooke.
Explanation:
Robert Hooke is a British scientist and he was the scientist that looked at cork and used the term "cells" to describe what he saw in 1665.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include cell membrane, nucleus, golgi apparatus, cytoplasm, ribosome, lysosome, chromosome, etc.
Answer:
Hooke the first was correct
