Answer:

a) Yes

b) Yes

c) Yes

d) Yes

Explanation:

a. In the exons?

Yes mutant site will be expected. It will transcript-ed as well and it can be a polypeptide depending on the mutation type.

b. In the intron?

Yes mutant site will be expected. It will be transcript-ed as well and it cannot be a  polypeptide  

c. In the promoter?

Yes mutant site will be expected. It will not be transcript-ed and it cannot be a  polypeptide

d. In the intron-exon boundary?

Yes mutant site will be expected. It will be transcript-ed and it cannot be a  polypeptide

Which of the following statements about gluconeogenesis in animal cells is true?
MakcuM [25]

Answer:

C. THE CONVERSION OF FRUCTOSE 1,6-BISPHOSPHATE to fructose- 6- phosphate is not catalyzed by phosphofructokinase -1, the enzyme involved in glycolysis.

Explanation:

This statement is true as the enzyme involved in this step is FRUCTOSE-1,6-BISPHOSPHATASE.

Gluconeogenesis is the coversion of non-carbohydrate molecules (lactic acid, amino acids, glycerol) through the pyruvic acid into glucose in the cells.

This process takes place mainly in the liver and occurs during periods of fasting, starvation, low carbohydrate diets.

The pathway of gluconeogenesis involves eleven steps of enzymatic catalyzed reactions.

In the conversion of fructose 1,6- bisphosphate to fructose-6-phosphate is catalyzed by fructose 1,6-bisphosphatase and not by phosphofructokinase -1 which is involved in glycolysis. This step is a rate-limiting step of the pathway.

The conversion of glucose-6-phospahte to glucose is not catalyzes by hexokinase but glucose -6- phosphatase.

Homeostatic regulation usually involves a(n) ________ that detects a particular stimulus, and a(n) ________ that responds to the
geniusboy [140]

Answer:

c) receptor; control center; effector.

Explanation:

Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.

For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.

How can I set up a wildflower classification key?
s344n2d4d5 [400]

Answer:

There are 3 methods to set up a wildflower classification means discovering a new flower. Those methods are discussed below in the explanation section.

Explanation:

Method one (Identification tools using):

  1. Search the about of the flower in the flower dictionary or flower database.
  2. Use any app which can identify flower such as Flowerchecker, Naturegate, etc.
  3. Take photos of the plant and post it on Flicker to get more information.
  4. Try google photos for searching about the plant by its picture.

Method two( Measuring the physical character of the plant):

  1. Measure the overall height of the plant.
  2. Measuring the width of the plant.
  3. Look at the flower to check how the flower is arranged on the stem.
  4. Count the petal number of the flower.
  5. Identify the color of the petals.
  6. Check the shape and texture of the stem.
  7. Check the shape, size, and arrangement of the leaves in the plant.
  8. Use this collected information to identify the flower in a plant database or encyclopedia.

Method three (Identifying the Flower’s Location and Blooming Time):

  1. Use the climate and terrain to determine the type of the flower.
  2. Observation of the factors in the geographic location to identify the flower.
  3. Find out the time of year when the flower bloomed.
  4. Identify the flower in an online database or encyclopedia using the collected information.

By doing this, you can set up a wildflower classification key and can find out the kingdom, family etc of the flower.
