What is an adaptive advantage of recombination between linked genes?
Georgia [21]

Answer:

New allele combinations are acted upon by natural selection.

Explanation:

Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.  

The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.

Thus, the correct answer is new allele combinations are acted upon by natural selection.

based on the fluid mosaic model of the cell membrane, which type of molecule can move passively across the membrane, without the
Monica [59]

Answer:

My guess would be H₂O/ water, since osmosis is a form of passive transport and I can't see the model the question references. Gases like O₂/ oxygen, CO₂/ carbon dioxide, and simple sugars like glucose can also pass through a cell membrane with passive transport though.

Suppose you discover a new form of a nucleic acid, XNA. Like DNA, it is double-stranded. You are interested in its mode of repli
victus00 [196]

Answer:

A: Unlike DNA, XNA replicates conservatively

Explanation:

<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>

In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.

Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.

Why do plants at the bottom of a pond grow better than plants at the bottom of a lake
STALIN [3.7K]

Since ponds are typically shallower than lakes, this allows more sunlight to reach pond plants than lake plants. By getting my sunlight, these pond plants can photosynthesize more efficiently.
