Murljashka [212]3 years ago
5 0

Answer: False

Explanation:

Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.

It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.

It depends on the state of activity. It transports more oxygen to the tissue that require it the most.

Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .

Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.

When an organism breaks down organic molecules, some of the energy that had been stored as chemical energy is lost as heat. this
Andrews [41]
<span>The right answer is: *some of the energy that had been stored as chemical energy is lost as heat.

Breaking down an organic molecule into smaller ones is part metabolism of all the living organisms. It is called catabolism.

Catabolism is the set of reactions of molecular degradation of the organism considered. It is the opposite of anabolism, all synthesis reactions. Catabolism and anabolism are the two components of metabolism.Catabolism reactions are oxidations (or dehydrogenations) and they are thermodynamically favorable, that is they are exergonic (yielding chemical energy, producing energy). A part of this energy is used for biological activities, like moving, building or binding molecules together. The other part is released as heat. (You can take an example in the real life like running, the energy lets you moving and produces by the way heat)</span>

Devise an experiment to test the hypothesis that bright orange coloration in butterflies acts as a "warning" to potential
Murrr4er [49]

Answer and Explanation:

As I don't have access to live butterflies, the control group would be clay models that do not exhibit warning coloration, e.g. beige / white / brown. In contrast, the experimental group would be the clay models that exhibir a strong warning coloration such as color orange / red.

After preparing the clay 'prey', I would locate them in specific places outside where birds are able to detect them. Moreover, I would use a webcam to monitor the recurrence of birds in the area.

1st experiment: Test whether birds approach the prey that exhibits both warning coloration (experimental group) and dull coloration (control group). Then, record the minutes they spent wandering near the prey.

2nd experiment: Test wheter birds feed on the prey that exhibits both warning coloration (experimental group) and dull coloration (control group). Record time.

Carry out statistical analyses.

Present results and discuss.
