In the above diagram of a plant cell, what is the function of structure 3?

kramer

Explanation:

B. serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

In mice, a male and female are mated, both with long ears. All female have long ears but half the males bave short ears and half

rjkz [21]

If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).

To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.

Thepotemich [5.8K]

Answer:

Avirulent.

Explanation:

VIRULENCE is the ability of a pathogenic organism to infects the host, leading to damages or death of the host. The extent of these virulent effect depends on certain chemical substances ( called Virulence factors) produced during the pathogenic processes.

The virulence effects is achieved due to the ability of the virulent factor to disrupt the entire physiological mechanisms of the organisms; e,g crop plants; though suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.

In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because

none of the d crop pant is completely diseased.

the nascent intenodes and leaves are growing to usual size.

Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.
