Explanation:
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.

Which elements are essential for living organisms to survive? Check all that apply.
carbon
polonium
sulfur
zinc
hydrogen
oxygen
nitrogen
Answer:
it's carbon, sulfur, hydrogen, oxygen, and nitrogen (A, C, E, F, G)
Explanation:
The most essential elements for the survival of living organisms are carbon, hydrogen, oxygen, and nitrogen.
Why oxygen is an important element?Oxygen is important for respiration and the energy-producing process that drives most living things' metabolisms. This is considered an element that is important for the life.
All life forms on Earth require carbon. Carbon intake and outflow are a feature of every plant and animal life, whether they take in carbon to help build food or release carbon through respiration.
Therefore, Oxygen, carbon, hydrogen, and nitrogen are important elements as 96% of the human body will be made with them.

Observe the dandelions shown here. What plant parts or structures can you identify? What differences can you observe between a dandelion leaf and flower?
Answer: External plant structures such as leaves, stems, roots, flowers, fruits, and seeds are known as plant organs. Each organ is an organized group of tissues that works together to perform a specific function. These structures can be divided into two groups: sexual reproductive and vegetative.
Many look-alike plants have similar leaves, but dandelion leaves are hairless. They generally have toothed edges that gave the plant its French name, “dent de lion.” Leaves and hollow flower stems grow directly from the rootstock. There is only one flower per stem, verses other branching look-alike plants.
The differences which one can observe between a dandelion leaf and flower are:
Dandelion leaves are hairless, flowers are notThe dandelion leaf has one flower in each stem, flowers do notThe plant parts and structures which are similar between a dandelion and flowers are:
LeavesStemsRoots, etcAccording to the given question, we can see that there is a need to show the similarities and differences between dandelion leafs and flower from the given image in the complete text.
As a result of this, it is important to note that dandelion leaves, although similar to the flower in the image, have hairless leaves and the edges have tooth like structures, which are not found in the flower.

In January, Earth is closest to the Sun in its orbit. Yet the Northern Hemisphere experiences winter. Which statement explains this phenomenon?
A.
Earth completes one precession cycle in January every year.
B.
The Northern Hemisphere is located at high latitudes.
C.
The Northern Hemisphere is tilted away from the Sun.
D.
The eccentricity of Earth’s orbit is high in January.
E.
The obliquity or tilt of Earth is greater than 23.5° in January.
Answer:
C. The Northern Hemisphere is tilted away from the sun
In January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun; this is option C.
What is Earth's axis tilt?The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun. This tilt is the primary reason for the seasons on Earth. As the Earth orbits around the Sun, the orientation of its axis relative to the Sun changes, resulting in different parts of the planet receiving varying amounts of sunlight throughout the year. When the Northern Hemisphere is tilted away from the Sun, as it is in January, the Sun's rays hit the Earth at a lower angle, resulting in less direct and less intense heat and light. This means that the Northern Hemisphere receives less sunlight and experiences colder temperatures, resulting in winter.
Hence, in January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun, which is option C.

B. the ability to make their own food
C. the need for a source of energy
D. the need for oxygen for respiration
Answer:
I am not sure but I believe it's c.the need for a source of energy
The characteristic is shared by all prokaryotic and eukaryotic organisms are that they need for a source of energy as to maintain the cell processes.
What is the difference between the prokaryotic and eukaryotic organisms?
The number one difference among those sorts of organisms is that eukaryotic cells have a membrane-certain nucleus and prokaryotic cells do not. The nucleus is wherein eukaryotes save their genetic information.
Mitochondria, for example, are organelles that offer eukaryotes with maximum in their power through generating power-wealthy molecules known as ATP. Prokaryotes lack mitochondria and as an alternative produce their ATP on their mobile floor membrane.Both eukaryotic and prokaryotic organisms get the power they want to develop and keep everyday cell characteristic thru cell respiratory. Cellular respiratory has 3 foremost stages: glycolysis, the citric acid cycle, and electron transport.

What happened to the oil released offshore? What effect could this have on resource availability for organisms that live near or around the shore?
Answer:
Damaged the marine organisms.
Explanation:
The oil released offshore causes damaged to the organisms lives at that region of water because oil is a non-polar solvent which spreads on the sea flood can adversely affected the fish and other aquatic organisms. The resources which are available to the organisms are decreases which leads to lowers the growth of aquatic animals as well as adversely affected the marine ecosystem near or around the sea shore.
Answer:
When oil is released offshore it causes damage to the organisms that live at that area in the water. Oil can spread on the sea floor and can negatively and toxically affect all of the organisms in the water. The resources that these organisms have to survive are decreasing. This leads to a lower survival rate and growth of the organisms. The organisms aren't the only things that are affected because the nearby marine ecosystem they live in is also in danger. If oil spills continue like this, our survival rate is also at risk.

An allele arises in a population that helps individuals digest cellulose. While the allele starts in only one organism, it increases in allele frequency because it allows organisms that carry it to reproduce more. What is this an example of
ANSWER: A NATURAL SELECTION.
EXPLANATION:
When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .
However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.
True or False: Samples that represent as much of the whole population as possible provide stronger evidence.

During experiment yeast fermentation ，how is the anerobic condition maintained to ensure that the fermentation process is completed？
Answer:
By covering the solution.
Explanation:
The anaerobic condition is maintained to ensure that the fermentation process is completed by covering the solution so that no oxygen enters the solution. Anaerobic conditions are necessary for the fermentation process because the anaerobic conditions allow the production of lactic acid, ethanol and carbondioxide gas from pyruvate. Without anaerobic condition, the fermentation process does not occur so that's why we can say that anaerobic conditions should be maintained for the fermentation process.
