Explain why autotrophs are on the bottom of the energy pyramid.
Answers
Answer:
Because Primary producers like plants are capable of making their own energy from the sun.
Explanation:
Producers make up the bottom of a pyramid. There are many organisms that feed on these producers and use their energy in their own biological processes. These organisms are higher in the pyramid.
Autotrophs are on the bottom of the energy pyramid; Because Primary producers like plants are capable of making their own energy from the sun.
Why do autotrophs always occupy the lowest level?The sun's energy is converted into biomass by autotrophs, the producers in a food web.
Each of the trophic level results in a drop in biomass. The Lower trophic levels always have more biomass than higher trophic levels.
Autotrophs are able to produce their food through photosynthesis; which means they provide food for all other creatures.
The Producers make up the bottom of a pyramid. There are lots of organisms that feed on these producers; use their energy in their own biological processes. These organisms are higher in the pyramid.

What happens to salivary amylase when it arrives with the bolus in the stomach? Because of this, what happens to carbohydrate digestion? (Hint: Look up the optimum pH for amylase and what is the pH of the gastric juices)
Answers
Answer:
Salivary amylase becomes inactive in stomach. Carbohydrate digestion halts until the bolus enters small intestine.
Explanation:
Salivary amylase is present in saliva and breaks down starch in food thus it helps in carbohydrate digestion. The optimum pH for its working is 6.8. As the bolus enters the stomach, pH drops drastically. Gastric juice has pH around 3. Salivary amylase is not able to function in such a low pH and becomes inactive in stomach. As a result, carbohydrate digestion halts in stomach. Gastric juice has its own amylase but it does not digest the starch much.
As the bolus enters the small intestine, the acidic pH is restored to neutral value. Carbohydrate digestion restarts with the help of pancreatic amylase.

What is this lesion?
A)Melanoma
B)Dysplastic nevus
C)Supernumerary nipple

Answers
Final answer:
The skin lesion described is probably not melanoma due to its regular borders and uniform pigmentation. It is more likely to be a dermatofibroma due to its benign characteristics. The correct answer is: D) Dermatofibroma
Explanation:
The lesion described in the question is a medium brown circular lesion with regular borders, evenly pigmented, and approximately 7 mm in diameter. According to the ABCDs of skin cancer, concerning characteristics include asymmetry, irregular borders, varied colors, and a diameter greater than 6 mm. Additionally, evolving shape and elevation are signs to watch for. The lesion here does not fit these criteria well, thereby making melanoma (option A) less likely. A dermatofibroma often presents as a firm, benign skin lesion with a smooth or slightly irregular border, varying in color from brown to pinkish, and they can sometimes be mistaken for moles. Dermatofibroma is a more appropriate diagnosis given the described characteristics.

Describe the trends in the wildebeest population over time when compared to the population affected by rinderpest disease
Answers
Answer:Eradication of the virus allowed the wildebeest population to rebound from around 200,000 animals in 1958 to around 1,200,000 in the late 1970s. Following this steep increase, the population stabilized.
Explanation:
The trends in the wildebeest population over time when compared to the population affected by rinderpest disease is maybe reproduction of the wildebeest after rinderpest vaccination worked on them.
What is the rinderpest?Cattle, wildebeest, and other animals with feet are susceptible to the viral disease known as rinderpest. For many years, the Serengeti region's cattle and wildlife had been afflicted by the disease.
My initial hypotheses for why the trends in the wildebeest and buffalo populations resemble each other are that both animals rose over time as a result of rinderpest vaccination or treatment, which boosted the trends for both animals.
Therefore, after the virus was eradicated, the wildebeest population recovered, increasing from 200,000 animals in 1958 to 1,200,000 in the late 1970s. The population stabilized after this abrupt rise.

Describe how increasing salinity affects the amount of fluid ejected each time a contractile vacuole contracts. Calculate the water potential ( Ψ ) of an animal cell without contractile vacuoles if water enters the cell and creates a solute potential ( ΨS ) of −2 . Assume that the pressure potential ( ΨP ) in the cell is 0.
Answers
Answer:
Water potential [tex]= -2[/tex]
Explanation:
As we know,
Water potential is equal to the sum of pressure potential and solute potential
Ψ [tex]=[/tex] ΨS [tex]+[/tex] ΨP
Where Ψ is the water potential
ΨS is the solute potential
ΨP is the pressure potential
Given -
Solute potential ( ΨS ) [tex]= -2[/tex]
Pressure potential ( ΨP ) [tex]= 0[/tex]
Substituting the given values, we get -
Ψ [tex]=[/tex] [tex]- 2 + 0[/tex]
Ψ [tex]=[/tex] [tex]- 2[/tex]
(a) Increased salinity will affect the amount of fluid ejected each time a contractile vacuole contracts because the surrounding water becomes more hypertonic as salinity increases.
As hypertonicity of the surrounding medium increases, water potential decreases, and more water will be ejected from the contractile vacuole to the surrounding medium as a result of osmosis.
(b) From the formula:
water potential ( Ψ ) = solute potential ( ΨS ) + pressure potential ( ΨP )
In this case, ΨS= -2 and ΨP = 0
Therefore:
Ψ = -2 + 0
= -2
Thus, the water potential of the animal cell without contractile vacuoles if water enters the cell and creates a solute potential ( ΨS ) of −2 would be -2.

A mutation occurs in an original DNA template that changes the DNA, changes the RNA, but does not change the protein sequence. What kind of mutation is this. and what would be the consequence of this original change?
Answers
Answer:
The changes that do not affect the function of a protein are called silent mutations.Explanation:
As given here as a mutation occurs in an original DNA template that changes the DNA, by transcription this mutation passes into RNA and changes the RNA, but it does not change the protein sequence, it means that this mutation could be silent mutation.
Silent mutation is the mutation which cause the change of a base in that, after the mutation the codon codes for the same amino acid, or the amino acid which do no cause any change in the protein, hence these changes do not affect the function of a protein.
A silent mutation is a type of mutation that does not change the protein sequence. It has no significant impact on the function or phenotype of the organism.
Explanation:
The mutation described in the question is a silent mutation. This type of mutation occurs when a change in the DNA sequence does not result in a change to the amino acid sequence of a protein. It typically involves a substitution of one nucleotide for another, which still codes for the same amino acid. As a result, the protein sequence remains unchanged.
The consequence of this original change is that there would be no significant impact on the function or phenotype of the organism. Silent mutations are often considered neutral mutations because they do not affect the protein's structure or function. They can accumulate in a population over time without causing any noticeable changes.

There are 10 ways to select 2 pieces of jewelry that are not bracelets.
How many ways can Lauren select 4 pieces of jewelry, of which exactly 2 are bracelets?
150

Explanation:
The question relates to the mathematical field of combinatory, particularly combinations. To find the total ways Lauren can choose her jewelry, we use the formula '(n choose 2) * (m choose 2)', where n is the number of bracelets and m is the number of other jewelry items.
Explanation:The subject of this question appears to be related to combinatorics, specifically, combination. If we suppose that there are 'n' bracelets and 'm' pieces of jewelry that aren't bracelets, Lauren has 'n choose 2' ways to select the bracelets and 'm choose 2' ways to select the other pieces of jewelry. Therefore, the total number of ways in which Lauren can choose her jewelry is the product of the two, i.e., '(n choose 2) × (m choose 2)'.
For example, if Lauren has 3 bracelets and 4 other types of jewelry to choose from, she can select the bracelets in '3 choose 2' = 3 ways, and the other pieces of jewelry in '4 choose 2' = 6 ways. Thus, she has a total of 3×6 = 18 possible ways to choose 2 bracelets and 2 other pieces of jewelry.

When a potassium ion (K+) moves from the soil into the vacuole of a cell on the surface of a root, itmust pass through several cellular structures. Which of the following correctly describes the order inwhich these structures will be encountered by the ion?
A) plasma membrane → primary cell wall → cytoplasm → vacuole
B) secondary cell wall → plasma membrane → primary cell wall → cytoplasm → vacuole
C) primary cell wall → plasma membrane → cytoplasm → vacuole
D) primary cell wall → plasma membrane → lysosome → cytoplasm → vacuole
E) primary cell wall → plasma membrane → cytoplasm → secondary cell wall → vacuole
Answers
Answer:
C) primary cell wall → plasma membrane → cytoplasm → vacuole
Explanation:
Structurally from the soil into the roots, the structure of the root cells is such a way that k+ enters with water through the primary cell wall → plasma membrane → cytoplasm → vacuole of the root hairs, and move through apoplastic and sympathic pathways from the root hairs .
From the root hairs they moved in mass flow in the xylem vessels. They reentered apoplastic and sympathic pathways again to reach different parts of the plants.
Due to the facts that K+ in the roots cells are of lower water potential,soil water K+ can also move by active transport and facilitated diffusion from the soil into the (primary cell wall → plasma membrane → cytoplasm → vacuole roots,) and later switch to apoplastic and sympathic pathways to reach plant parts.
A potassium ion moving from the soil into a plant cell first encounters the primary cell wall, then the plasma membrane, followed by the cytoplasm, and finally it reaches the vacuole. Hence, the correct sequence is primary cell wall → plasma membrane → cytoplasm → vacuole. Hence the correct option is (C).
Explanation:When a potassium ion (K+) moves from the soil into a plant root cell, the order in which it encounters the cellular structures is important. The correct sequence is as follows: the potassium ion first interacts with the primary cell wall, which is the outermost layer.
Following this, it passes through the plasma membrane, which regulates the movement of substances into and out of the cell. After crossing the plasma membrane, it moves through the cytoplasm of the cell, which is the substance inside a cell where most of the cell's metabolic reactions occur.
Finally, the potassium ion reaches the vacuole, a cellular organelle that stores nutrients and aids in waste disposal. Therefore, option C) primary cell wall → plasma membrane → cytoplasm → vacuole describes the correct order of structures encountered by the ion.

Answers
Answer:
21 chromosomes
Explanation:
Meiosis is a type of cell division that produces 4 haploid daughter cells (i.e., gametes) from a single diploid cell. This parental cell undergo one (1) cycle of DNA replication and two (2) cell divisions, thereby, in the case of the Norway rats that have 42 chromosomes, the final number will be 21 (21 x 2= 42)
Answer:
21 chromosomes and 21 molecules of DNA at the end of meiosis II
Explanation:
The end of meiosis II that occurs on each cell will give rise to four mature cells, or gametes, and each cell will have 21 chromosomes because the number of each cell has to be half of the initial diploid cell to allow the correct number after the formation of the zygote. Each cell will also contain 21 molecules of DNA because the mature cell after the meiosis has to be haploid.
