Answers

The term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.

What is an Ecosystem?

An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, space, and shelter.

Saguaro cactus provides nesting sites (space), food, and water to other animals of the Sonoran Desert and allows them to survive and reproduce in a much better way. This refers to the biotic factor of an ecosystem.

Therefore, the term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.

Answer:

A change in one base of the gene sequence is known as point mutation.

Explanation:

Question 2 is incomplete.

3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.

In Point mutations there is substitution of one base for another.

Example:                TAT TGG CTA            

                              TAC TGG CTA

The  TAT changes to TAC which shows point mutation.

4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.

When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.

Tim scraped his knee during a fall and it needs to be repaired. The closest skin cells begin sending out growth factors through paracrine signaling to tell all nearby skin cells to start replicating to repair the damaged area.

What are the next steps once the message is sent?
A) The growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing.
B) The growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells near and far. The cells start mitosis.
C) The growth factors are packaged into a vesicle and secreted from a cell that acts upon only a target nearby cell. The cell starts swelling up.
D) The growth factors are packaged into a vesicle and embedded into the plasma membrane where it is detected by other cells. The cells produce more proteins.

Answers

Answer:

It is B all the other answers are for other types of injuries, knee scrapes don’t swell, it might divide, and it would produce more protein

Explanation:

Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells all nearby cells. The cells start dividing, which is present in Option A.

What happens during cell repair?

When the cell breaks, then the nearby cells release the paracrine signaling that goes to the cells and stimulates the cells to make the mitosis process and divide, which includes DNA replication, protein synthesis, and RNA synthesis, and then from the original cells, the daughter cells are formed and fill the gap that is formed in the injury and the far cells don't get the signal as the paracrine factors acts nearby.

Hence, Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing, which is present in Option A.

Answers

Humans exhibit twenty-two (22) pairs of autosomes or autosomic chromosomes which are distinct from sex chromosomes X and Y.

What is an autosome?

An autosome can be defined as any chromosome in a somatic/germinal cell that is not a sexual chromosome (i.e., autosomes are not x chromosomes and Y chromosomes).

Autosomes contain essential genes required both in women and men in order to synthesize structural and enzymatic proteins present in their cells.

What was the most likely reason these finches evolved into different species?

A. They interbred with other bird species.


B. They adapted to different food sources.


C. The beaks provided a variation for survival in extreme climates.


D. The beaks prevented them from being seen by predators

Answers

Answer:

The breaks provided a variation for survival in extreme climates.

Explanation:

The most likely reason these finches evolved into different species is the beaks provided a variation for survival in extreme climates.

What do you mean by Species?

Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.

The finches evolved to have different beak shapes because they adapted to different food sources. But when these variations are passed on to the next 10 to 12 generations, reproduction isolation has been observed. From here it can be said that a new species have been evolved.

Therefore, the most likely reason these finches evolved into different species is the beaks provided a variation for survival in extreme climates.

Write a short report discussing these pollutants.Answer: Point source pollutant: My school is situated near a river. A wastewater treatment plant is a few miles away. The plant uses certain chemicals to treat wastewater, but releases effluents into the river. Although the plant regulates the released effluents, the treatment system gets overloaded during heavy rainfall. As a result, untreated chemicals and wastes enter the river. The plant thus becomes a point source pollutant for the river. The wastes and chemicals entering the river adversely affect growth of plants and fishes in the water body. Non -point source pollutant: I live in a residential area that has a groundwater reservoir. Last month, the authorities in my area complained that the water in the reservoir was getting polluted. On investigating, they found that rainwater picks up debris and pollutants from roads and sidewalks as it flows on its path. The polluted water enters waterways that are connected to the groundwater reservoir. The debris and pollutants are many in number, and it was difficult to trace exactly where the rainwater picked them up. However, these pollutants affect large areas because the water from the groundwater reservoir reaches many homes.
