Answer:

Environmentalists are concerned about the introduction of genetically engineered trees because the transgenic cause effects such as gene transfer to wild relatives and weed propagation, changes in productivity and degradation of soils, with these trees there is greater demand for water and few opportunities for nutrients to be recycled

Genetically engineered trees have effects on Human Health, they can produce resistance to antibiotics and generation of allergies.

katrin2010 [14]

Answer:

Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.

If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.

8. Crossing over is an exchange of corresponding segments between nonsister

prisoha [69]

The main benefit of crossing over is that it increases genetic diversity.

<h2>Crossing over and Genetic Diversity</h2>

Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells.

The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.

Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment.

In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.

Answer:

The grasshopper doesn't have to use it circulatory system to carry gases to and from the grasshopper cells because the air that is passed through the trachea system is already close enough to get to the cells.

Explanation:

"In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process. There is not even an oxygen-carrying pigment in insect hemolymph." - www.biology-pages.info
