What is amino acid?

Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.

On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.

A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation

Answers

As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you

Answers

Answer:

In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.

The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

Answers

I am pretty sure it is A

Answer:

Heterotrophy, Autotrophy

Reasoning: Heterotrophy organisms are organisms who can't retrieve food themselves and use energy and sunlight in order to get their food, which is exactly what plant cells do. Autotrophy is the ability to produce things such as carbon dioxide and oxygen, which plants do as well. Hence, Heterotrophy and Autotrophy are the most reasonable answers.
