Answer:

No oxygen and no carbondioxide gas.

Explanation:

The cabbage parts have access to water and sunlight but no oxygen and carbondioxide gas because plastic bag has no open part from which he takes oxygen gas that is needed for respiration as well as carbondioxide gas that is required by the plants in the process of photosynthesis. So we can say that in the plastic bag no respiration and photosynthesis occur.

Brine shrimp live in salt water, but the level of salt in the water where they reside can differ dramatically from day to day or
Naily [24]

Answer:

The correct answer is "excretes; hypotonic; absorbs, hypertonic".

Explanation:

Cell's homeostasis is only conserved in an isotonic solution, since cells that are in an hypertonic solution (high salt concentration) tend to loss water, and in hypotonic solution (low salt concentration) tend to absorb water. Brine shrimp lives in waters that are both, hypertonic and hypotonic and has adapted to overcome this issue by excreting and absorbing salt across its gills. In very high salt concentrations, a brine shrimp "excretes" salt across its gills and maintains an internal salt concentration that is "hypotonic" relative to the water where it lives. In lower salt concentrations, a brine shrimp "absorbs" salt water across its gills and maintains an internal salt concentration that is "hypertonic" relative to the water where it lives.

wolverine [178]

Answer:

Natural selection causes change in allele frequencies within a population.          

So option A is correct one.

Explanation:

Natural selection generally  work  on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
