name three ways that you can explore specific genes to see if they would make good barcodes for species identification.

Answers

The barcode gene sequences should show less intraspecific gene variation than interspecific variation, contain conserved flanking regions and have a short length.

The three most important constraints to explore the suitability of a nucleotide sequence in order to be used as a DNA barcode for taxonomic identifications are:

Barcode gene sequences show less genetic variation within species (intraspecific variation) than between species (interspecific variation).

Barcode sequences also show conserved flanking regions in order to be amplified in all species to be identified/categorized.

Barcode sequences have short lengths due to technical constraints (amplification by PCR is ideal no more than 1000 base pairs).

For example, in animals, an excellent barcode gene sequence used for taxonomic identification is the Cytochrome Oxidase I (COI) gene because this sequence can be used across the evolutionary spectrum.

When do plants make the most sugar?

Answers

Answer: All green plants make sugar through photosynthesis, the process plants use to transform the sun’s energy into food.

Explanation:

Answer:

Both photosynthesis and respiration occur within plant cells. During the day, photosynthesis is the dominant process in plants. This means that the plant produces more glucose than it uses during respiration. At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process.

A student made a model of an onion skin cell she viewed
using a microscope. The scale is 500:1. The student's cell
model has a length of 15 cm.
How many centimeters is the real cell's length?
A. 7500 cm
B. 0.002 cm
C. 33 cm
D. 0.03 cm

Answers

If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.

The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.

Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.

              15 x 1/500

                             = 0.03 cm
