Explanation:
Cytosine, guanine, thymine and adenine are NOT referred to as phosphates (they are nitrogen bases), whereas DNA is in the shape of a double helix'.
A nucleotide is made up of sugar, phosphate and a nitrogen base.The replication is performed after cell division.Adenine always pairs with thymine, whereas cytosine pairs with guanine.Complementary base pairing matches up nitrogen bases.The letters that make up the DNA molecule code for genes.Replication results in two strands of DNA, each of which has half of the original strand.Hydrogen bonds hold nitrogen bases together, forming the rings of the DNA ladder.In conclusion, Cytosine, guanine, thymine and adenine are NOT referred to as phosphates (they are nitrogen bases), whereas DNA is in the shape of a double helix.

In the diagram of the DNA molecule below, match the correct term with the image (ignore the blank arrow).
Answer:
hope this help
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.

The growth of plants stop if its apical part is cut,why？
Answer:
On some kinds of plants, the meristem is arranged so that when the tip of a branch or stem - which contains the apical meristem, from which new growth is initiated - is cut off, new stems or branches are signaled to start growing from the side, an area called the cambium or lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new branches.
Explanation:
good luck
Answer:
The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down the stem towards the axillary bud... When the apical is removed bud I'd removed, the lowered IAA concentration allow the lateral buds to grow and produce new shoots, which compete to become the lead growth
Two species benefit from interaction with each other
Example: A hummingbird gets food from the nectar of a flower and then spreads the nectar’s pollen, helping the flower reproduce.
: One species benefits from the interaction, and the other species is harmed but not necessarily killed
Example: Ticks feed on other animals’ blood, which can hurt the other animals.
: One species benefits from the interaction, and the other species is neither helped nor harmed
Example: Egrets rely on cows to stir up dirt and bring food to the surface, but cows do not benefit.

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?
In decimal form this is 0.5 and it converts to 50%
===================================================
Explanation:
Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%
This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.

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.

Answer:
Yes.
Explanation:
Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.
Which of the following would likely move through the phospholipids of the
cell membrane most easily? *
CO2
Glucose
K+
Starch
Answer:
CO2
Explanation:
Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.
It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.
What is the structure of cell membrane ?According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.
