Answer:

d. dendrites; axon

Explanation:

The structure of a neuron contains the stem-like structure at one end, the cell body contains the nucleus and the long tube-like structure covered with a myelin sheath called axons.

The axons carry the signal away from the cell body in sensory neurons and the dendrites carry the information towards the cell body.

The signals are transmitted in the form of electrical signals which gets converted into the chemical signal at the synaptic junction through the neurotransmitters released by the synaptic knobs.

Thus, Option-D is the correct answer.

Did the detergents containing enzymes work better at removing stains than those containing no enzyme? Why or why not?
Mandarinka [93]

Answer:

Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.

Interstitial cells produce?
Elanso [62]

Answer:

The correct answer is option E (testosterone).

Explanation:

The interstitial cells or Leydig cells are the individual or group of cells present in loose connective tissues surrounding the seminiferous tubules.

They are usually active in the production of dominant sex hormones in males that is testosterone responsible for male secondary sexual characteristics.They produce hormones in the presence of luteinizing hormone (LH) and growth hormone released by the pituitary gland.

The high cholesterol content and crystals of Reinke make the leydig cells appear pale in color.

Thus, option E- testosterone is the correct answer.

The producers-Sea weed-Perform photosynthesis.

The filter feeders- sponges, chiton-eat floating planktons.

Grazers -Snails,mussels feed on- floating planktons.

Carnivores such as sea stars feeds on snails

Explanation:

  • The producers are placed at the bottom level in energy pyramid and are prime factor in the aquatic eco system which provides energy and perform photosynthesis with the help of water,sunlight and chlorophyll.
  • The filter feeders are those that feeds upon small particles that are present in the water.
  • Grazers are those organisms that feeds on producers like phytoplanktons.
  • Carnivores are those organisms that feeds on herbivores.

The carbon that plants need for photosynthesis comes from...?
ArbitrLikvidat [17]
Plants take in that carbon dioxide<span> from the air, and take in water (H2O) as well. Photosynthesis produces a chemical reaction that creates glucose, or C6H12O6, out of CO2 and H2O. 

Hope this helps!
