Explain what causes spring and neap tides, and identify

Biology
2 answers:
ivann1987 [24]2 years ago

Answer:

Spring tides occur when the moon is full or new. The moon's gravity and the Sun's gravity pull Earth's crust and ocean water. This causes tides to be higher than normal. At neap tide, the moon and the Sun are at right angles to each other

Answer:

Spring tides occur when the sun, moon and earth are lined up, and it causes high and low tides to be much higher (moon is full/new). Neap tides occur when the sun, moon, and earth form a right angle this causes regular high and low tides to be much lower (first quarter and last quarter moon). The moons gravity and suns gravity pull the earths crust and ocean water.

When energy is added which bond is formed?
Sauron [17]
In all types of chemical reactions, bonds are broken and reassembled to form new products. However, in exothermic, endothermic, and all chemical reactions, it takes energy to break the existing chemical bonds and energy is released when the new bonds form.

Provide a summary of what happens during DNA replication using the following words: Helicase, DNA
scZoUnD [109]

Answer:

Please find the summary of what happens during DNA replication below

Explanation:

DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:

- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.

- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.

- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.

- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.

After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

Minerals _____
Effectus [21]
B. Must be inorganic, minerals are obviously not the same thing as rocks, and are only a part of rocks. They cannot be gases, as minerals typically exist as solids. The logical choice is B!
