Answer:
A gland that secretes hormones
Explanation:
Exocrine glands are the tissue which can secrete organic compounds in the human body and secrete them through the process of exocytosis. The exocrine glands secrete the secretion through the ducts into the body cavity. They do not secrete the blood into the bloodstream but in the body cavities.
In the given question, the characteristic which is not performed by the exocrine gland is the secretion of hormones as they are produced by the endocrine glands which strictly pour them into the bloodstream.
Thus, the selected option is the correct answer.
Answer:
1 and 4
Explanation:
Streptobacilli are linked together in chains, the bacterium is gram positive and the generally rod-shape. The genus could be aerobic ( required oxygen for their growth), falcultative anaerobe (in the absence of oxygen, they can switch to fermentation).
Answer:
Light was a limiting factor for photosynthesis under the given conditions. Light is required for photosynthesis.
Explanation:
According to Blackman's principle of limiting factors, the rate of photosynthesis is regulated by the factor which is present below the minimal value. Photosynthesis is regulated by many factors such as CO2 concentration, temperature, light intensity, etc. However, under particular conditions, the factor present below the minimum levels regulate its rate.
In the experiment, when the light intensity was present below its minimum levels, an increase in the light intensity increased the rate of photosynthesis. Here, light intensity was the limiting factor and no other factors such as CO2 or temperature would affect the rate of photosynthesis.
Once the light intensity reaches its optimal levels, other factors become limiting and there is no further increase in the rate of photosynthesis by increasing the light intensity.
