Answer:

The correct answer is option 2. Common ancestry.

Explanation:

The homologous structure is the structure that has a similar anatomical structure or underlying skeleton and can perform a different function in different organisms.

Homologous structures are similar in different organisms because they diverge from a common ancestor. All organisms that have homologous structures are considered to have a common ancestry. for example, human arm, dogs forearm, bat's wing all have a similar skeleton structure

Thus, the correct answer is option 2. Common ancestry.

What is one way that creativity made up for limited technology for early biologists?

Vedmedyk [2.9K]

Creativity is an important tool for scientists because it can often make up for the limitations of the current technology that scientists in different fields, not only biologists, are facing. For that reason, early biologists could think of and apply innovative and creative ways how to measure a certain thing they were interested which then came around the limitations of the technology they were using :)

Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)

Grace [21]

Answer:

i believe the answer is 2)

Explanation:

because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**

good luck :)

hopefully, this helps

**please let me know if this was incorrect**

have a nice day !!

1. A future offspring has just been conceived. When does it have the highest level of potency?

Brums [2.3K]

Answer:

When a future offspring has just been conceived it has the highest level of potency in Totipotency.

Explanation:

Potency is the ability of cells to differentiate. AT different stages of development the level of potency changes. The highest level of potency is Totipotency and these cells have the ability to develop a whole organism. The common examples are spores and zygote. In embryonic stage the cells are Pluripotent and they can differentiate into different type of cells. Pluripotent cells after further development changes into Multipotent cells. Unipotent cells have the least potency and can develop only in one cell linage.

30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.

31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.

32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

33.amino acids

For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein

34.Peptide Bonds

Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).
