The answer is A because that’s the only thing plants “breath”
Answer:
Internal receptor: Internal receptors present on the cytoplasm, and also known as cytoplasmic or intracellular receptor. These Internal receptors respond to hydrophobic ligand molecules which can travel across the plasma membrane. These receptors can influence (directly) the gene expression means how much a specific protein is produced from a gene without having to pass the signal on the other receptor.
Cell-surface receptor: cell-surface receptor is present on the cell membrane is known as trans-membrane receptors. This trans-membrane receptor binds to external ligand molecules which cannot travel across the cell membrane. They are also called cell-specific proteins because they are specific to individual cell type. The cell-surface receptor has 3 main components:
1) External ligand-binding domain.
2) Hydrophobic membrane-spanning region.
3) Intracellular domain.
Answer:
C
Explanation:
The production of ATP is greatest at 50o C as indicates by the production of CO2 in the Krebs Cycle
Answer:
<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>
<u></u>
Explanation:
Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.
Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:
- photoreceptors
- mechanoreceptors
- chemoreceptors
- thermoreceptors
Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
Answer:
a. Odds ratio = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning
Explanation:
For case study
Let 'a' represent the total population of people with melanomia = 696
Let 'b' represent the total number of people with melanomia exposed to indoor tanning = 1107 – 696 = 411 people
For control study
Let 'c' represent the total population = 1500
Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)
= 1500 - 723
Total number of people not exposed to indoor tanning = 777 people
a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)
= 1.69 / 1.07 = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
