Aphids get resistant to pesticides often.

<h3><u>Explanation</u>:</h3>

Aphids are the small bugs that are found in plants and are generally green to red in colour. Aphids are often found to be resistant to the common organophosphates or anticholinesterase pesticides that are commonly used. They do this by means of one of the three processes.

The normal genotype which has no resistance mechanism did respond to the insecticide by up-regulating 183 genes. These genes were mostly related to energy metabolism, detoxifying enzymes, proteins of extra cellular transport, peptidases and cuticular proteins.

The second mechanism of the is seen in second genotype which is resistant through a kdr sodium channel mutation. They up-regulated 17 genes which are coding for detoxifying enzymes, peptidase and cuticular proteins.

The third mechanism is seen in those groups which are multiply resistant genotype that carrying kdr and a modified acetylcholinesterase. They are found to up-regulated only 7 genes and appeard not to require induced insecticide detoxification. Instead they down-regulated many genes.

Which allele for human blood type is recessive?

sergij07 [2.7K]

Blood type doesn't fall into the category of dominant/recessive genes exactly; rather it combines this with the properties of incomplete dominance. Ignoring the Rh factor, there are 3 alleles for blood type, I^a,I^b, and i. You will be type A if you have I^a I^a or I^a i and type B if you have I^b I^b or I^b i. You can also get type AB by having the combination I^a I^b or be type O if you have i i. If you need to use dominant/recessive, you can say the A and B allele are dominant over the O allele and codominant with one another.

Which two features indicate that a cell is a plant cell and not an animal cell? A. cell membrane, flagella B. lysosome, vacuole

Triss [41]

c. cell wall, vacuole

Among the choices above, the two features that indicate that a cell is a plant cell is the cell wall and vacuole. The cell wall can only be found in plant cells. It is the rigid cell that surrounds the cell membrane. The vacuole of a plant cell and animal cell are way too different. The vacuole of an animal cell is usually more than one and small, even smaller that that of the plant cell. On the other hand, the vacuole of the plant cell is only one in fact a large one that takes up almost 90 percent of the volume of the cell

The intrinsic rate of the atrioventricular av bundle is beats min quizlet

Misha Larkins [42]

The intrinsic rate of the atrioventricular av bundle is 40 to 60 beats per minute (bpm).

<h3>What is the Atrioventricular (AV) and the intrinsic rate?</h3>

Atrioventricular (AV) can be regarded as the block that usually altered the interruption of impulse transmission between the atria to the ventricles.

And this have the 40 to 60 beats per minute (bpm) as the intrinsic rate.
