Biology
2 answers:
ivann1987 [24]3 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.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the labor
PSYCHO15rus [73]

A mutation is an alteration in the original DNA sequence.  Option 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material.

Mutations alter DNI sequences and introduce new variants. Many of these variants are eliminated, but some of them might succeed and be incorporated in each individual, affecting the entire species.

They can be damaging or beneficial. These last mutations are the ones that have been selected by natural selection.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level. They can change the bases sequences and bases pairing.

Mutations depend on each group's environment and its ecological pressures, and they accumulate in time. They are inherited to the followings generation and get to spread.

According to this framework, the correct option is 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

If the analyzed chemical is a mutagen, then it will cause an alteration in the DNA sequence and this change -mutation- will pass to the following generations spreading in the population.

  1. The cells die within hours of being exposed to the chemical.
  2. The cells grow more quickly than those that were not exposed to the chemical.
  3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
