Explanation:
Nucleic acids are made up of chains of many repeating units called nucleotides (see bottom left of Figure 1 below). The DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral.) Nucleic acid molecules are incredibly complex, containing the code that guarantees the accurate ordering of the 20 amino acids in all proteins made by living cells. Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist.
This figure is a diagram of a short stretch of a DNA molecule which is unwound and flattened for clarity. The boxed area at the lower left encloses one nucleotide. Each nucleotide is itself make of three subunits:
A five carbon sugar called deoxyribose (Labeled S)
A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P)
And one of four nitrogen-containing molecules called nucleotides . (Labeled A, T, C, or G)
Alternating sugar and phosphate units form the two sides of a ladder-shaped arrangement with the rungs or steps each formed by a pair of nucleotide bases. Figure 2 below shows the structural formula of DNA in greater detail. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings. Only certain bases can pair together to form base pairs. In DNA, Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions. The side of the chain on the left begins with a free phosphate group at the top and ends with a sugar molecule at the bottom. In contrast, the complementary chain on the right begins at the top with a sugar molecule and ends at the bottom with a phosphate group.
Happily, it is not necessary to hold the details of DNA structure in your mind at all times! As the sugar and phosphate sides of the molecule are constant they are frequently represented by parallel lines. Even better, each of the nitrogen bases is conveniently represented by the first letter of its name. These conventions allow the simplified representation of the molecule shown in the figure below
Or, even easier, a section of a DNA molecule is often abbreviated to show the bases of just one strand:
A T G G C T A C
Knowing the base pairing convention of A always pairing with T and G always pairing with C makes the complementary strand of the molecule understood. It is this feature of complementary base pairing that insures an exact duplicate of each DNA molecule will be passed to its daughter cells when a cell divides.
If a telescope could zoom even further in, and look beyond the hdf , what do you think they would see?
Which space telescope is used to see distant objects?
The Hubble Space Telescope, often known as HST or Hubble, is an observatory that was put into low-Earth orbit in 1990 and is still in use today.Although it wasn't the first space telescope, it is one of the biggest and most useful ones. It is famous for being both an essential scientific tool and a public relations success for astronomy.The only telescope made with astronaut maintenance in mind is Hubble. Five Space Shuttle trips have been used to replace, improve, and repair the telescope's systems.Since Hubble is orbiting outside of Earth's distorted atmosphere, it can take extraordinarily high-resolution pictures with a lot less background light than ground-based telescopes can.The Hubble telescope and other space telescopes can be used to zoom at distant objects.

why photosynthesis is important
Answer:
It is important because plants would not be able to produce food for themselves, so the plant would die. Animals that feed on plants would not be able to survive, and animals that feed on other animals would die too because they would not have any food.

When biologists talk about a population of organisms, they are referring to
A) all the organisms in a particular area
B) all the organisms all over the world
C) all the organisms of one species in a particular area
D) all the organisms of one species all over the world
Answer:
C because it couldn't be D
When biologists talk about a population of organisms, they are referring to all the organisms of one species in a particular area. Therefore, option (C) is correct.
A population is a group of individuals of the same species living in a particular geographical area and capable of interbreeding. This means that they share a gene pool and can produce fertile offspring. The size and characteristics of a population can be influenced by various factors, such as environmental conditions, competition for resources, predation, and disease.
Studying populations is essential for understanding how ecosystems function and how they may respond to changes in the environment or human activities, such as habitat destruction or climate change.

Explanation:
What elements are needed to carry out photosynthesis? Select all that apply.
Answer:
You need carbon dioxide, sunlight, and water.
Explanation:
Answer:
1.
1.Light or photochemical reactions.
They require the presence of sunlight, which is transformed into chemical energy usable by organisms in the form of ATP, these reactions occur in thylakoids, and for their more detailed study, photochemical reactions are classified as cyclic photophosphorylation and non-cyclic photophosphorylation.
2.Carbon fixation reactions or reactions in the dark.
They require or not the presence of sunlight, and they are reactions that will occur in the stomata.
3.Chemosynthesis.
They take inorganic compounds and O2 from the environment and combine them inside their cells and as a result of these reactions energy is released (exergonic reactions) applying it in the synthesis of ATP (endergonic reactions), forming inorganic by-products.
Biological importance of photosynthesis:
Photosynthesis is surely the most important biochemical process in the biosphere for several reasons:
1. Every year some 200,000 million tons of carbon is used in the photosynthetic process.
2. The synthesis of organic matter from inorganic is carried out mainly through photosynthesis; that will go from some living beings to others through the food chains.
3. Produces the transformation of light energy into chemical energy, necessary and used by living beings.
4. Oxygen is released, which will be used in aerobic respiration as an oxidant.
5. It is the cause of the change produced in the primitive atmosphere, which was Anaerobic and reductive.
6. The energy stored in fossil fuels such as Coal, Oil, and Natural Gas also depends on it.
7. It is responsible for maintaining the necessary balance between Autotrophic and Heterotrophic beings.
8. During the process, dioxygen is released into the atmosphere, which implies:
Convection currents transfer thermal energy ____.
a. as a result of buoyancy
b. from warmer regions to cooler regions
c. between continents
d. from cooler regions to warmer regions

The energy is not being created or destroyed: only transformed.
Total energy does not stay the same as some is always lost as heat.
Ο Ο
Energy stays the same because the energy has no where to go but in a system.
Answer:
The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. ... Once the potential energy locked in carbohydrates is converted into kinetic energy (energy in use or motion), the organism will get no more until energy is input again.
