Answer: The threats of environmental changes to the fitness, survival and reproductive success of individuals, and ultimately to the survival of species and ecosystems come from many directions: habitat destruction, disruption of food chains, changes in disease and parasitic loads, increased pollution and direct and indirect
Explanation:
I think the correct answer from the choices listed above is option A. Autotrophic protists are different from the heterotrophic protists in a sense that t<span>he autotrophic protists can photosynthesize, while the heterotrophic protists cannot. Hope this answers the question.</span>
Answer:
A) 48
B) 96
C) 48
D) 48
Explanation:
Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.
For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.
Answer:
See Below.
Explanation:
The main function of the plants leaves is to create it's own food source via photosynthesis which produces glucose as one of it's products. Transpiration also occurs in the plant leaves where water evaporates out of the leaf increasing the concentration gradient, allowing more water to move up via the xylem via a column of water.
The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.
Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-
1. Merkel corpuscles- detect pressure and roughness on skin.
2. Ruffini corpuscles- detect deep tension in skin, skin stretch.
3. Meissner corpuscles- perception of light touch and slip on skin.
4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.
When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.
