Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.

Explanation:
If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.

the earliest form of spongy bone in a developing long bone is termed
Answer:
Osteoid
Explanation:
The earliest form of spongy bone in a developing long bone is termed as Osteoid.
Osteoid is defined as the the unmineralized, matrix material that is made up of a fibrous protein, collagen, and mucopolysaccharide and forms prior to the maturation of bone tissue.
Osteoblasts, the process of formation of bones takes place when inorganic salts starts depositing over osteoid to form the hardened material.
Hence, the correct answer is "Osteoid".
Explain whether a mutation in any cell of an organism can be passed on to offspring of the organism. Under what conditions is a
mutation passed on to the next generation?

Type your answer below
Answer:
Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova. The other kind of cells, somatic cells, are the rest of the cells in the body, and mutations that occur in these cells do not get passed on to offspring.

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the tenth place and do not include units.)
Answer:
See Explanation
Explanation:
The question is incomplete as the diameters of the Willapa Bay urchins were not given.
However, I'll give a general way to solve this problem.
Average is calculated using:
[tex]Average = \frac{\sum x}{n}[/tex]
i.e. Sum of all diameters divided by the number of bay urchins.
The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.
10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm
Using the above data, the average is:
[tex]Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}[/tex]
[tex]Average= \frac{86}{10}[/tex]
[tex]Average= 8.6[/tex]

What causes the appearance of the Moon to change over time?
A
The orbit of the Earth around the Moon and its distance from the Sun.
B
The Moon's position relative to the Sun and Earth as it revolves around
Sun.
с
The rotation of the Moon on its axis.
The distance of the Moon to the Sun.
D
Answer:
B
Explanation:
The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .
Answer:
As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.
Explanation:
Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.
