Answer:
The photosynthesis and cellular respiration cycle is used to produce usable energy for plants and other organisms. These processes occur on a molecular level inside the cells of organisms. On this scale, energy-containing molecules are put through metabolic processes that yield energy that can be used right away.
Answer:
Sea otters affected biodiversity because they control the populations of sea urchins, which endanger kelp forests. Kelp forests are important because they convert sunlight to living material, and they also provide food and habitat to sea creatures. Kelp is important in sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable for the large size of abalones in California.
Answer:
1. During DNA replication, an open section of DNA, in which a DNA polymerase can replicate DNA, is called a replication fork.
2. After replication is complete, the new DNAs, called daughter DNAs, are identical to each other.
3. The enzyme that can replicate DNA is called DNA polymerase.
4. Okazaki fragmentsare the short sections of DNA that are synthesized on the lagging strand of the replicating DNA.
5. The new DNA strand that grows continuously in the 5' to 3' direction is called the leading strand.
Explanation:
DNA replication is a process that occurs during the interphase (S phase) of the cell cycle and in which DNA is replicated. DNA replication is semiconservative which means that each strand in the double helix (leading strand and lagging strand) acts as a template for synthesis of a new, complementary strand that will become daughter DNA.
DNA polymerase is the main enzyme of the DNA synthesis: it requires primer (short sequence of DNA) for the initiation and it performs its function only in one direction 5'-3'. Other enzymes involved in DNA replication are DNA primase, DNA helicase, DNA ligase, and topoisomerase.
Answer:
The model is inaccurate because the base pairs are incorrect.
Explanation:
The model of DNA that the student made was:
G-G
A-A
T-T
C-C
G-G
A-A
T-T
C-C
The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.
The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.
<span>Mangrove forests cannot
withstand freezing temperature that is why they can only grow at tropical and
subtropical latitudes whereas salt marshes grow in middle to high latitudes. Mangrove
forests can be recognized by their tangle of roots that allow them to stand
still on stilts above water. The roots of the mangrove trees slow the movement
of tidal waters causing the sediments to settle out of water and build up the muddy
bottom. For salt marshes, they are coastal wetlands that are flooded and
drained by salt water brought by tidal waves. The difference between the two is
that mangrove forests are woodlands and salt marshes are coastal wetlands. </span>
