Answer: Plants

Cotton is a a soft, staple fiber that is obtained from the seeds of cotton plant, which belong to the genus Gossypium. The fiber is spun into yarn or thread that is used to make cloths. It is a highly valuable fiber for textile industry.

Cotton is a plant, hence 'cotton plantations.'

In a population of birds some individuals are born with thicker, stronger beaks than others. This is a trait that is inherited.

C)The two species cannot have viable offspring together.

An ecological niche can be defined as the functional role played by the organism or species in order to survive in it's habitat. Like the type of food consumed by the organism, type of mating mating season and others.

In the given situation, the thick beak birds likely to develop in a new species because of this typically adaptation. The two species may exhibit reproductive isolation as they may not be capable of inbreeding among themselves and cannot produce viable offspring together.

What would be the best negative control to use when testing for any organic compounds

ra1l [238]

Explanation:

A similar question was asked online, here is the answer it gave:

'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'

My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.

Ann took 4 glasses of water with different colors, then placed cabbage in it. She observed the setting before and after 8 hrs. W

maw [93]

Plants absorb water from the ground. In the experiment, we can see that cabbage leaves take water from the glasses through the process of transpiration. Together with water the leaves absorb the pigments.

<h3 />

Experiment

1) Four glasses of water, each with a different color ⇒ red, blue, yellow, orange

2) One or two cabbage leaves are placed in each glass and left there for eight hours.

3) After 8 hours, the leafs turn into the color of the colored-water in which they are placed.

<h3>Explanation</h3>

When placing cabbage leaves in the glasses, they start to absorb water from the stems.

As they absorb water to drive it to other parts of the leaf, they also absorb the pigments that are giving color to the water.

As time passes by, the leaves acquire the same color as the water.

<h3>Water absorption: Transpiration</h3>

Plants absorb water from the ground. This process is known as transpiration.

Roots are the first organ that gets in touch with water.

The xylem in roots and stems is in charge of this process.

The xylem composes the vascular system that transports water and minerals through its vessels and tracheids from the roots to the aerial parts of the plants.

Water can move from the ground to the aerial parts of the plant thanks to osmosis and hydric gradient potential.
