Answer:
Introducing evasive species to a food web can damage the ecosystem as the existing life depends on each other. Having a new organism come in and take extra food harms the organisms that eat that food, and in turn if there is nothing left from (lets say the carnivores), the producers will have very little nutrients to absorb from the soil. Once the producers die, the herbivores will die because they have no food. Then the chain of death will continue till there's nothing left.
Explanation:
The question is incomplete as it does not have the options which are:
A) eight legs.
B) two pairs of antennae.
C) a sessile lifestyle.
D) an open circulatory system.
E) parapodia.
Answer:
D) an open circulatory system.
Explanation:
In the given question, the characteristics of an organism are given which are:
1. Exoskeleton- outer covering composed of cuticle
2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses
3. modified segmentation- segmented bodies
All these characteristics show that the organism belongs to the Arthropods group of animals.
The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.
Thus, Option-D is the correct answer.
Answer:
Candida invades tissues by producing the exoenzymes <u>protease</u> and <u>phospholipase</u>.
Explanation:
Candida is a genus of yeast and a member of the fungi kingdom. It is the most common cause of fungal infections like oral thrush, candidiasis, and vaginal yeast infections.
<u>Candida produces the exoenzymes </u><u>protease </u><u>and </u><u>phospholipase</u><u>, which help in invading and spreading the infection in the host cells.</u>
Answer:
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
Explanation:
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
The speed of a wave c, its wavelength λ and frequency f are all related according to c=λf. So if c is the same for all EM waves, then if you (say) double the frequency of a wave, its wavelength will halve.
