The mammalian tail and
cluponka [151]

The mammalian tail and the human coccyx, the leaves of pitcher plants and cacti, are homologous organs while, the flippers of penguins and dolphins, as well as the shells of turtles and crabs are analogous structures.

<h3>What are homologous organs?</h3>

Homologous organs are those that are similar in structure but operate differently. They resulted from divergent evolution.

Divergent evolution occurs when species are closely connected to the same ancestors but develop similar structures that perform different tasks in different environments.

Analogous Organs are organs from various creatures that, despite their appearance, perform the same function.

In the given case, the mammalian tail and coccyx, as well as the leaves of pitcher plants and cacti, are homologous organs, whereas penguin and dolphin flippers, as well as turtle and crab shells, are analogous structures.

Thus, these are the different instances of homologous and analogous organs.

Are cells living or non living
ludmilkaskok [199]

Answer:

CELLS! Living things use energy, move, consume water and food, etc. Any individual form of life that is capable of growing and reproducing is considered an organism. All organisms get water and other materials from the environment.

The degree to which the findings of a study may be applied to a larger population represents how ___________ a sample is. A. Ina
g100num [7]

Answer:

B. Generalizable

Explanation:

Generalizable means something's ability to be applied to a general or wide group. So, if something is generalizable that means that it is applicable to a wide group of things outside of the initial study. Thus, B is the correct answer because it is the only vocab word that properly describes how widely applicable the study is.

One of the best ways to generalize a study is to use random or probability sampling. This helps ensure that the findings of the study can be used by others in different situations.

proteins need to be denatured using an anionic detergent such as sds before gel electrophoresis because: select all that apply.
grandymaker [24]

The majority of proteins contain a uniform positive charge, and a uniform neutral charge, and most proteins have intricate three-dimensional structures that might affect how well they travel through the gel electrophoresis. For these reasons, proteins need to be denatured. Here, the right answers are A, B, and D.

Protein separation is accomplished using a molecular technique called sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which operates in the proximity of an electric charge. Proteins are separated using SDS-PAGE according to their electrophoretic mobility. Protein charge, shape, and structure all affect electrophoretic mobility.

To proceed in the direction of the positive terminal, the protein molecules need to have a constant negative charge (anode). The overall charge of a protein is determined by the amino acid content of the protein as well as the charge of the individual amino acids.

Thus, depending on the total makeup of amino acids, the charge may change. Depending on the ratio of different amino acids, the total charge of the proteins can be positive, negative, or neutral. The SDS treatment gives the proteins a consistent, negative charge. Then, according to size, the negatively charged amino acids flow toward the positive terminal.

Complete question:

Proteins need to be denatured using an anionic detergent such as SDS before gel electrophoresis because: Select all that apply.

A - most proteins have a uniform positive charge

B - most proteins have complex three-dimensional structures that can impact their movement through the gel

C - the overall charge of a protein depends on the amino acid composition of the protein and can vary greatly

D - most proteins have a uniform neutral charge
