While biodiversity includes the number of species in a given area, it also includes:- overall number of trophic levels in a food web.
- unique phylogenetic lineages.
- abiotic factors that define the community.
- amount of primary productivity.

Answers

Answer 1
Answer:

''Unique phylogenetic lineages.'' is the correct answer.

What is biodiversity?

Biodiversity is the total number of species that are present in a place.

Biodiversity helps in the measuring of variation at the species, genetic, and ecosystem level. Phylogenetic lineage shows the relationship between different biological species so we can conclude that ''Unique phylogenetic lineages.'' is the right statement.

Answer 2
Answer:

Answer:

Unique phylogenetic lineages. (Ans. B)

Explanation:

Biodiversity: It is defined as the total species or variety of species present in a place on earth. This variety common measurement is known as species richness, it is defined as the count of species present in an area.

It is helping in to measure variation at the species, genetic, and ecosystem level. Phylogenetic lineage showing the relationship (evolutionary) between different biological species. Their phylogeny is determined by the differences and similarities in their genetic characters.

Why are Dichotomous keys so hard to do.

Answers

A dichotomous key is a sequence of methods which allows the identification of a living thing.  This key will consist of a series of options or choices that lead the user to the right name of a given item. This is so hard to do because it involves the six taxa. You also need to gather all the significant details and characteristics of the specimen. What makes it harder is the fact that living things are always variable so you need not to rely on a single observation.

Final answer:

Dichotomous keys might seem difficult because they require accurate observations and understanding of specific biological vocabulary. However, with practice, usage of dichotomous keys can become easier. It's similar to learning a new language.

Explanation:

Dichotomous keys might seem challenging because they require a high level of attention to detail and understanding of specific biological terminology. However, with practice, they become easier to use. A dichotomous key is a tool used in biology to identify an unknown organism by going through a series of choices that lead the user to the correct name of a given item.

To correctly use a dichotomous key, you must carefully observe the organism in question and make accurate observations. Then, you follow the key, making decisions based on your observations. This often involves detailed, specific biological vocabulary and precise measurements which some students may initially find overwhelming.

However, remember that with practice and usage, becoming proficient with dichotomous keys is completely achievable. It's essentially like learning a new language! Once you get the hang of it, it can be a valuable tool in your biological studies.

DNA replication analogy? Needs to include the roles of helicase, DNA polymerase, exonuclease, and ligase

Answers

Answer:The leading strand is smoothly repeated, while every five feet the lagging strand is like driving down a street with a stop sign. In small single strands, the lagging strand must be repeated, while the stand is combined by DNA ligase. The DNA helicase is an essential multi-subunit protein in the replication process because it combines ATP's exergonic hydrolysis with the unwinding of the double helix of the DNA. In the initiation complex (the collection o collection o), additional proteins must be recruited.DNA polymerase is responsible for the DNA replication process, during which a molecule of double-stranded DNA is copied into two identical molecules of DNA. The power of DNA polymerase molecules to copy DNA molecules into test tubes through polymerase chain reaction, also known as PCR, has been used by scientists.DNA polymerase is responsible for the mechanism of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules. Scientists have exploited the power of DNA polymerase molecules to copy DNA molecules into test tubes by polymerase chain reaction, also known as PCR.

When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it was because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? A) Ask his mother to make the plant better. B) Wait and see what happens to the plant. C) Remove the plant from direct sunlight after a week. D) Ask his science teacher at school what she thinks could be the reason.

Answers

The way that Jeremy can best support the idea that his plant needs more sunlight is wait and see what happens to the plant (option B).

Why do plants need sunlight?

Every living organism requires energy (ATP) from one source or the other. Plants are immobile organisms that get their own energy source from the sunlight.

The energy from the sun (light energy) helps them to perform photosynthesis and synthesize their own food (nutrition).

According to this question, Jeremy was told by his mother that his plant didn't grow because of inadequate sunlight. The only way to know if this is really the case is to wait and see.

Straps fastened around a horse's legs to restrain their movements are called A. twitches.
B. hobbles.
C. leashes.
D. halters.

Answers

The correct answer is option B

The straps or spancel is a device which is used to limit the walk of the animals like horses, donkeys, et cetera.

This device tethering one or more legs together to limit their movement so that they cannot go far away. It is mostly used in horses.

Sometimes hobbles are used on other animals when they are trained to stay still in a particular position.
B. hobbles. Think of the definition of "to hobble." It's means to have difficulty walking. Hopefully that will help you remember.
