Down-cut

Explanation:

Lowering a streams base level will cause the stream to down-cut and erode to that level.

  • The base level of a stream is the lowest level to which a stream can erode its channel.
  • The base level of most streams is usually a function of their ability to down-cut their bed rock.
  • Most streams have their base level equal to that of the sea level.
  • When a stream downcuts to its base level, it becomes rejuvenated and gains more energy.

Use the drop-down menus to put the events of the light-dependent reaction of photosynthesis in the correct order.
mash [69]

Events of the light-dependent reaction of photosynthesis starts with the absorption of sunlight and ends with ATP production.

<h3>Events of  light-dependent reaction</h3>
  • In the first step energy is absorbed from the sun and then water is broken down.
  • Hydrogen ions of the water molecules are transported across the thylakoid membrane.
  • NADPH is produced from NADP+.
  • Hydrogen ions diffuse through the protein channel.
  • ADP turns into ATP.

Drupady [299]

Answer:

The correct answer would be - mycobacterium, and streptomyces.

Explanation:

Actinobacteria is a phylum that consists of a group of gram-positive bacteria with cytosine and guanine content in their DNA. These bacteria can be aquatic or land bacteria. Actinobacteria do not have cell wall however they make a non-sptate and mycelium.

Mycobacterium is one of the genera of the actinobacterium phylum. This genus includes pathogenic species in it that cause deadly diseases in humans and other mammals such as leprosy and tuberculosis Whereas streptomyces is another genus of the actinobacteria that is yielded the very first drug to fight with the ancient scourge.

Thus, the correct answer is - mycobacterium and streptomyces.

julsineya [31]
The answer is D. This is an exmaple of incomplete dominance. Red and blue make purple. Because there is no purple alleles, C is false. Because there you can only have 2 alleles total B is false. A is false because having two red alleles makes a red flower.

Ligases are enzymes that link two dna fragments together. Suppose a bacterium develops a mutation in the ligase gene needed for
Goryan [66]

Answer:

Cell will not replicate because of incomplete DNA replication.

Explanation:

DNA replication is crucial for reproduction/replication of any organism as it involves the duplication of genetic material. So if an organism is unable to perform proper DNA replication it would not be able to reproduce.

DNA polymerase is the enzyme that synthesize the new DNA strand in DNA replication. DNA polymerase can synthesize a strand only in 5'→3' direction. Both of the strands of DNA molecules are opposite in direction. So one strand is synthesized continuously called as leading strand while the other strand is synthesized in form of okazaki fragments called as lagging strand.

The okazaki fragments are joined together by the enzyme ligase. So if Ligase enzyme is absent in bacteria it would not be able to synthesize the lagging strand of DNA and thus could not be able to produce a replica of DNA. And if there is No replication of DNA then No replication of cell would occur.
