A student designs an experiment to determine the effect of sunlight on plant growth. He or she places three identical plants on three different window sills, which permit different amounts of sunlight exposure. Each plant receives the same amount of water each day. What is the responding variable in this experiment? A.plant growth B.amount of sunlight
C.amount of water
D.type of plant

Answers

The responding variable in this experiment of the students experiment where she places three identical plants on three different window sills which were expose to different amounts of sunlight exposure and same amount of water each day is the amount of sunlight because even the plant receives the same amount of water but each of them didn't expose the same amount of sunlight than the growth of the plant will not be the same.

Answer;

Swollen veins


Swollen veins might be a symptom of a person whose vein valves are not functioning properly and are causing fluid it flow away from the heart.


Explanation;

Valves are structures that are found in the circulatory system both in the heart and the veins.

They function to prevent the back flow of blood.

They do so by ensuring the continuous flow of blood in one direction.

If the valves are not functioning properly it may lead to various effects such as swollen veins due to the back flow of blood which may lead to the pooling of blood in the extremities.

The answer is C. swollen veins.

Good luck :)

What is the major reason why fungus-like protists are not fungi?

Answers

Fungal-like protists includes parasitic and predatory molds, water molds (Class Oomycota), and terrestrial slime molds (Myxomycota). 
These both move and lack the chitin that helps define true fungi. 
These fungal/amoeboid Myxomycota have a motile life stage fungi do not. However they do produce fruiting bodies to reproduce as do some fungi. Slime molds have an amoeboid phagotrophic (feeding) phase of their life cycle and use their pseudopodia to move and eat. In their mobile life stage they lack cell walls. 
Oomycota are aquatic fungi-like protists. They are water molds & plant parasites known as white rusts, and downy mildews. They have cell walls composed of cellulose, not chitin like true fungi. 
The sexual reproduction has heterogamous sex cells and asexual reproduction has motile spores (zoospores swim not sperm). The zoospores, with two flagella, are their asexual means of dispersal in water and damp soil.
Fungi have both sexual reproduction and asexual budding in yeast (that is not binary fission like bacteria). 
They are not capable of independent movement like an animal; they are sessile like a plant. 
Fungi are heterotrophic and use external enzymatic digestion of food stomach they digest their food outside their bodies and absorb the digested nutrients, this makes them osmotrophs instead of phagotrophs, which engulf their food.
Hope This helped! :D
The major, simple reason is that they can move while mushrooms cannot.
