8 0

Answer:

<h2>Facilitated diffusion .</h2>

Explanation:

1. Diffusion: it  is the net passive movement of particles from  higher concentration to lower concentration. Diffusion continues until the concentration of substances is equal through out.

 

2. Facilitated diffusion: is the  process of passive transport of molecules or ions across a biological membrane and requires (via) a specific carrier protein.

3. Facilitated diffusion is passive type and require specific protein and it  requires no energy from the cell.  

4. It requires specific proteins through which molecules move from one side to another.

Describe what messages are sent by the nervous system when you go outside wearing a sweater on a very hot day.​
mr_godi [17]

Answer and Explanation:

In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:

  • The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
  • Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
  • The metabolic rate falls so that the body generates less heat. You also become less active
  • Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.

What is the sequence and polarity of the dna strand complementary to the strand 5' aaatgtccatgc 3'?
Natalka [10]

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA

DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule

5' AAATGTCCATGC 3'

3' -TTACAGGTACG -5'   is the sequence and polarity of the dna strand complementary to the strand 5' aaatgtccatgc 3'.

Of the following choices, what is the approximate LD50 of the least toxic substance? 20 mg/kg, 70 mg/kg, or 130 mg/kg
pychu [463]

The approximate LD50 of the least toxic substance will be 130 mg/Kg.

  • The dose necessary to cause the death of 50% of a population under test after a predetermined test period is known as the LD50 value for a drug.
  • Commonly used as a broad indicator of a substance's acute toxicity are LD50 values.
  • Greater toxicity is indicated by a lower LD50. A low LD50 of 500 mg/kg or less implies severe toxicity.
  • Moderate toxicity is indicated by an LD50 of 500 to 1,000 mg/kg. A modest toxicity level of 1,000 to 2,000 mg/kg is indicated.
  • The species is especially vulnerable to the poison if the LD50 is low. The lethal dose (LD50) of a specific poison might change significantly between several animal species.
  • Thus out of all the options, LD50 130 mg/kg will have the lowest toxicity and 20 mg/kg will be the highest.
