What do the data suggest about the effects of cane toads on the predatory behavior of black snakes in areas where the toads have

been present for 40–60 years?
a. Black snakes in areas where cane toads have been present for 40–60 years are just as likely to prey on cane toads as on native frogs.
b. Black snakes will prey on cane toads in areas where cane toads have been present for 40–60 years, but not when offered a native frog instead.
c. Black snakes will not prey on cane toads in areas where cane toads have been present for 40–60 years.

Answer: C. Black snakes will not prey on cane toads in areas where cane toads have been present for 40–60 years.

Explanation:

Cane toad secret a toxin called bufotoxin which is a defense mechanism against predators. These defense mechanism is capable of killing black snakes if they eat cane toads. Within a period of 40 to 60 years, the black snakes in these area will be aware of the presence of a toxin capable of killing them in cane toads and will not prey on them. This phenomenon is termed learned behavioral adaptation.

shusha [124]

Answer:

<em>A. Both are eukaryotic</em>

Explanation:

Despite the fact that termites are insects that eat wood, termites are not equipped for processing wood all alone. Endosymbionts like trichonympha that live inside the digestive tracts of the termite help with converting over the wood into nutrients that the termite can process.

Trichonympha have the enzymes that can convert cellulose in wood into starches and sugars that the termite can use for their nutrition. In return, these living beings profit by the nonstop supply of energy rich cellulose and an appropriate domain in which to live. Both trichonympha and termites show mutualism.

How is the process of photosynthesis taking place thru Calvin Cycle?
Juli2301 [7.4K]

This is the ideal question! Thanks for asking!

Before we start, let's go through a mini-review.

Photosynthesis:

The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.

Calvin Cycle:

A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.

So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?

In plants, carbon dioxide (CO2CO2CO2​C, O, start subscript, 2, end subscript)  enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."

Carbon atoms from CO2 CO2 CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

That's about it! If you'd like, check out the attachment for a visual!

Thank you,
