Fiddler crabs are invertebrates. That means they do not have a backbone (that's made out of vertebrae). Does this mean they don't have a skeleton?
Answer:
they do have skeleton which is called exoskeleton, main component is chitin
Fiddler crabs don't have a skeleton. Instead, they occupy a carapace, a rectangular shell. As they expand, the carapace is absorbed, and a new, larger one is produced.
What are invertebrates?
The paraphyletic group of animals known as invertebrates lacks the notochord-derived vertebral column and does not even develop one. Except for the chordate subphylum, all animals fall within this classification.
To assist remove food from sand, they frequently dine in a watery puddle. Because both of a female's claws are little, she has an advantage over a male in terms of finding and consuming food. Feeding is more challenging for older males due of their main claw.
Therefore, fiddler crabs don't have a skeleton.

Explanation:
Pasteur disproved spontaneous generation by demonstrating that microorganisms did not grow in broth that was heated in swan-neck flasks and then allowed to sit undisturbed for several days. It was important that he placed the broth in control and experimental flasks before heating rather than transferring the broth to new flasks after heating. Why?
Answer:
See the answer below
Explanation:
It was important for Pasteur to place the broth in the flasks before heating rather than transferring it to new flasks after heating because the new flasks might be a source of contaminants in the form of microorganisms, hence, leading to a biased outcome.
In order to prevent cross-contamination and preserve the integrity of the outcome of the experiment, the broth needed to be placed in the flasks before heating instead of transferring it after heating.

2) Feathers allow for flight.
3) Feathers control what a bird looks like by supplying the bird with colors.

Feathers insulate birds from water and cold temperatures. They may also be plucked to line the nest and provide insulation to the eggs and young. The individual feathers in the wings and tail play important roles in controlling flight. Some species have a crest of feathers on their heads.
Feathers perform some of the functions for a fowl: 1) They offer insulation, the frame temperature of maximum birds is maintained at around 40 C; 2) Feathers allow for flight; 3) Feathers manage what a chook looks as if by way of imparting the chicken with hues.

Which of the following is NOT a true statement regarding macromolecules
The correct option associated with the question is given as follows:
a.All macromolecules are monomers.
b.All macromolecules are polymers made up of smaller units.
c.All macromolecules are created by dehydration reactions.
d.All macromolecules contain carbon.
Answer:
The correct answer is: a. All macromolecules are monomers.
Explanation:
Macromolecules are huge biological molecules made out of thousands of covalently associated atoms. Carbohydrates, lipids, proteins, and nucleic acids are altogether macromolecules. Macromolecules are framed by numerous monomers connecting together, shaping a polymer.
In doing such, monomers discharge water atoms as side products. This kind of reaction is called dehydration reaction, which signifies "to assemble while losing water."
lipids are worked from an alternate arrangement of monomers that look like each other in creation and size. Lipids are not polymers, since they are not made up of monomers.
An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, and banana were placed in separate containers at different areas around the school. The containers allowed the fruit flies to enter, but the fruit flies were unable to escape. After one day, observations were made by the students. Which best describes an error the students made in the experiment? A) too many types of fruit were used B) fruit flies were unable to escape C) different areas around the school were used D) one day is not long enough for the experiment
Answer:
C
Explanation:
The error that the student made was to place the containers for the different fruits in different areas around the school.
In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.
The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.
The correct option is C.

How does reducing gene flow cause speciation?
Reducing gene flow causes speciation because the species are not allowed to exchange genetic material.
How does reducing gene flow cause speciation?When gene flow is blocked from exchanging between populations, this results in speciation that prevents the populations of the same species to exchange genetic material.
