<h3><u>Answer;</u></h3>

It occurs over many generations.

It happens at the genetic level.

<h3><u>Explanation</u>;</h3>
  • <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
  • <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
  • <em><u>Therefore, evolution will only occur when there is change in gene frequency within a population over a given period of time. Genetic differences that are heritable are passed to the next generation.</u></em>

A researcher has developed two stains for use with seed plants. One stains sporophyte tissue blue; the other stains gametophyte
sukhopar [10]

Answer:

A) The pollen grains will be pure red.

Explanation:

Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).  

In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte).  When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.

Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.

What are brodmann areas and how do they relate to the neurological deficits that occur as the result of stroke?.
Viefleur [7K]

The Brodmann areas are a method of mapping the cortex and its distinct functions that was developed by Korbinian Brodmann, after whom the areas are named.

Korbinian Brodmann (November 17, 1868 – August 22, 1918) was a German neurologist best known for classifying the cerebral cortex into 52 distinct regions based on cytoarchitectonic (histological) characteristics. These areas are now commonly known as Brodmann areas.

The Brodmann classification divides the cortex into approximately 52 sequentially numbered areas, though some regions have since been subdivided and others are only found in non-human primates.

It is in charge of motor movements such as contralateral finger/hand/wrist or orofacial movements, learned motor sequences, breathing control, and voluntary blinking. The primary visual cortex (Brodmann area 17) is located on the medial surface of the occipital lobe, in and on either side of the calcarine sulcus.
