The diagram above shows four steps in an attempt to investigate the release of gas during photosynthesis. Each setup was kept at
Lena [83]

Answer:

light

Explanation:

The above experiment is an investigation on the factors that affect photosynthesis which include carbon dioxide concentration,light intensity and quality,chlorophyll, water and temperature.Light was the independent variable. When the lant is moved to an area where light intensity is low, the rate of photosynthesis decreases.

After the experiment, oxygen gas is produced being a by-product of photosynthesis. Plants that are not adapted to an aquatic environment are not suitable for this experiment. The amount of carbon dioxide dissolved in water is low.

Trace the ductal pathway from the epididymis to the urethra. (Module 26.5C)
iragen [17]

Answer:

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra

Explanation:

Epididymis is a tube that connects the back side of the testicles to the vas deferens (ductus deferens). The vas deferens is the connecting link between epididymis and urinary tract/urethra and is responsible for transporting sperm to the urethra. Seminal vesicles are small glands that lie above the prostate gland and make up more than 50% of the total semen. Seminal vesicles are connected to the vas deferens through ejaculatory duct. This duct empties sperm and semen into the urethra

Hence, the correct order is

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra

In our bodies, enzymes in our saliva and pancreas hydrolyse polysaccarides like starch and dissacharides (sucrose) to produce gl
Stolb23 [73]

Explanation:

The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it

In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.

  • Prepare a starch solution and spread into tubes
  • Prepare an amylase solution and spread into tubes
  • Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
  • Adjust the temperature of the tubes reaction to 37 celsius degrees.

The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.

  • Pipette the starch solution in the tubes with enzymes.

By the final step the glucose will be produced by the enzymatic digestion of amylase.

It's attached the scheme of the hydrolyzation of a starch strain

In a garden with trees and shrubs, green and pink katydids were observed. Over time, birds started feeding on the katydids. Whic
densk [106]

The right options are;  

A.The population of pink katydids will decrease.

B.The population of green katydids will decrease.

What will eventually happen to the population of the katydids is that the population of both the pink and green katydids will decrease. The predators which are the birds that feeds on the katydids (prey) will negatively influence the size of the prey populations by reducing them.
