3 0

Answer: False

Explanation:

Active transport is the movement of molecules from a region of lower concentration to a region of higher concentration across the cell in a concentration gradient. It requires the use of energy .

Passive transport is the movement of molecules in and out of the cell from higher concentration to lower concentration without the use of energy.

How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present
Greeley [361]

Answer:

This could result in a mutation.

Explanation:

A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.

OlgaM077 [116]

A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is <u>genetically identical</u> to the parent.

Answer: Option C

<u>Explanation:</u>

Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.

whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.
