Write a micro-theme (a short 100-300 word essay) on the importance of the study of biology.
Hello! Need a little help kind of confused. Thanks in advance!
Answer:
Science Question: When the plant is exposed to light for longer periods of time, it's height increases more than those plants that weren't exposed to light for as long.
Control: I think the control would be a plant that was exposed to light for 24 hours (all day). Not completely sure, but that's what i would say. (If you aren't sure what a control is, it's just a sample that you don't change at all. It's used to compare other samples' results.)

The brain stem consists of the ________. Group of answer choices midbrain, medulla, and pons cerebrum, pons, midbrain, and medulla midbrain only pons, medulla, cerebellum, and midbrain
Hey there! I'm happy to help!
The cerebellum is in the back of the brain and it helps with balance and reflexes, but it isn't part of the actual brain stem, so that is not the right answer choice.
The cerebrum is the front part of the brain made up of the many different lobes. Its ultimate goal is to help with thought, movement, and language. This is not part of the brain stem.
The brain stem consists of the midbrain, medulla, and pons. The midbrain is the uppermost part with the pons below it and the medulla oblongata below the pons.
The midbrain is important for functions such as eye and body movement. The pons aids with body signaling and the medulla oblongata also aids with reflexes and involuntary actions (as it is close to the cerebellum). The brain stem as a whole helps with respiration, heart rate, and blood pressure.

How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
Which of the following is not a functional group that can bond with carbon?
а
carbonyl
b
hydroxyl
C
sodium
d
phosphate
Sodium is not a functional group that can bond with carbon (Option C)
A functional group is a combination of atoms in a molecule that is capable of conferring particular chemical and physical properties.The most common functional groups include the carboxylic acids groups (CO2H), carbonyl groups (C=O), alcohol groups (-OH), ester groups (CO2R), and amine groups (NH2).Functional groups are observed along the carbon backbone of the biomolecules.This carbon backbone is made up of chains/rings of carbon atoms with the occasional substitution of an element (e.g., N or O).Learn more in:

Compare the apparent brightness of our Sun from Earth to the apparent brightness of our Sun from Neptune. Explain.
I'll mark brainliest
Answer:
s i
Explanation:
ESPEO HBEARRTEAUDADOY
According to research, the brightness of the sun from earth is about 900 times brighter than that experienced on planet neptune.
Planet Neptune is one of the 9 planets which orbits the sun. Due it's size and distance from the sun, the apparent brightness of the sun on earth is more than the brightness experienced on planet Neptune. In terms of distance, planet Neptune is more than 30 times farther from the sun than planet Earth, hence, reducing the apparent brightness of the sun it experiences. Also, Neptune is a far bigger planet than the earth. It is the third biggest of the nine planets. This could also have an effect on the sun's brightness on the planet due to larger coverage area.Learn more : https://brainly.com/question/20968688

Global warming is largely due to this increase in atmospheric carbon dioxide.
Explain how increases in atmospheric carbon dioxide concentrations contribute to global warming.
Answer:
Humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly by burning fossil fuels, but also from cutting down carbon-absorbing forests.
Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have increased since the beginning of the industrial period which lead to the Global Warming and it also causes the depletion of Ozone layer
which orgnaisms transform nitrogen to a form that is useful to plants
Answer:
Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
Explanation:
Answer:
Nitrogen fixing bacteria
Explanation:
Atmospheric nitrogen is in the form of
N
2
. This molecule is exceptionally stable and unable to be used by plants. The Lewis dot structure of
N
2
is
: N :::N:
The triple bond between the two nitrogens is very strong. However nitrogen fixing bacteria can attach to the the unused paired electrons on the outside of the nitrogen molecule. The bacteria use the energy from the broken bond for life functions and produce Nitrates and Nitrites as by products. Nitrates (
N
O

) and nitrites (
N
