How can you tell from a food web which organisms will have the greatest biomass?

Answers

Answer:

You can tell by which animals are at the top of the food chain.

Explanation:

You can tell this because if you count all the biomass below the animals at the top of the food web (which eat all the biomass below it), there is much more biomass below these animals (the ones at the top of the food chain), than any other animal below it. For example, if the rat ate a grasshopper it will receive its biomass, but if the python then eats the rat, then the python will be getting the biomass of the rat and the grasshopper, compared to the rat just getting the biomass of the grasshopper. So since there is much more biomass below the animals at the top of the food web, this means that the animals at the top of the food web receive the most biomass (when they eat the animals below them) out of the whole food web individuals.

Strong contrasts in texture have what effect on a monochromatic design?

Answers

Answer:

It prevents monotony

Explanation:

Strong contrasts in texture have a primary effect on monochromatic design by ensuring it’s more eye catching and not too plain.

Contrasts is a term used to describe the display of an objects dissimilar sides. A monochromatic light is known to have just one color and the strong contrasting texture however makes it possible for it to have different color differences thereby preventing monotony.

What are the parts of an operon?

Answers

Answer:

An operon consists of an operator, promoter, regulator, and structural genes. The regulator gene codes for a repressor protein that binds to the operator, obstructing the promoter  of the structural genes. The regulator does not have to be adjacent to other genes in the operon.

Mark me brainliestt :))

Answer:

An operon consists of an operator, promoter, regulator, and structural genes.

Explanation:

Promoter – a nucleotide sequence that enables a gene to be transcribed. The promoter is recognized by RNA polymerase, which then initiates transcription. Operator – a segment of DNA to which a repressor binds.

what function does DNA performs in eukaryotes​

Answers

Answer:

DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

Explanation:

Function of DNA is that it stores all the coded information for the function of the cell and the cells role in the development of a multi cellular organisms.

Where is DNA in eukaryotes?

In nucleus the eukaryotes, the cell's genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

How much DNA is present in eukaryotes?

Eukaryotes typically have much more DNA than prokaryotes, the human genome is roughly 3 billion base pairs while the E. coli genome is roughly 4 million.

Bony Fish (bass etc.) and marine mammals (like dolphins) evolved some similar adaptations for survival in aquatic environments. However, they evolved separately and are not closely related evolutionarily. What type of evolution does this represent?

Answers

Answer:

Convergent evolution

Explanation:

Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.

1. Catalytic converters reduce which of the following pairs of pollutants in car exhaust? a.)Carbon dioxide and ozone
b.)Carbon monoxide and hydrocarbons
c.)Carbon dioxide and particulates
d.) Lead and mercury
e.)Methane and particulates​

Answers

Answer: B

Explanation: By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) from the engine into less harmful carbon dioxide (CO2), nitrogen and water vapour.

The catalytic converter used in the exhaust of the cars reduces carbon mono oxide and hydrocarbons.

What is a catalytic converter?

The catalytic converters are the devices used in the exhaust of the vehicles run on petrol and diesel.

They convert the harmful toxic gases into the less harmful pollutants by a redox reaction.

By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC).

Biochemistry involves the production and degradation of biological molecules such as nucleic acids, proteins, lipids, carbohydrates, and vitamins. Changes in the production or degradation of these important molecules can cause disorders and diseases in humans. For each of the human disorders and diseases listed below, indicate whether it is caused by a change in: (A) nucleic acids (for example: DNA or RNA); (B) amino acids/proteins; (C) lipids (for example: cholesterol or triglycerides); (D) carbohydrates/sugars; or (E) vitamins. Provide only one (1) answer for each disease.

Answers

Answer:

Disorders are present below.

Explanation:

Degradation of nucleic acids causes Lesch-Nyhan syndrome and mitochondrial depletion syndromes in human body, degradation of proteins causes phenylketonuria and tyrosinemia diseases in humans, degradation of lipids causes Gaucher disease and Tay-Sachs disease. Due to these diseases of lipids, we have not enough enzymes to break down lipids, degradation of carbohydrates leads to diabetic ketoacidosis, hyperosmolar coma and hypoglycemia, and degradation of vitamins causes anemia and scurvy diseases in the body.

Which of the following is believed to be common among all mass extinction events?(1 point)

a significant change in the global climate

the type of species that went extinct

the type of event that causes the extinction

the number of species that went extinct

Answers

Answer:

D the type of event that causes the extinction

The correct answer is a significant change in the global climate, as due to this is believed to be common among all mass extinction events.

Climate extrude interacts with threats which include habitat loss and overharvesting to similarly exacerbate species declines. The decline of species and ecosystems can then boost up weather extrude, growing a remarks loop that similarly exacerbates the situation.

What is global mass extinction?

The mass extinction is an end result of human activity, pushed through populace boom and overconsumption of the earth's herbal resources. The 2019 international biodiversity evaluation through IPBES asserts that out of an expected eight million species, 1 million plant and animal species are presently threatened with extinction.

Therefore it is clear that a significant change in the global climate is believed to be common among all mass extinction events.

while looking at a graph, you notice a period of time where the line is perfectly horizontal what is most likely taking place during this time period

Answers

Answer:

The correct answer would be - the y-axis variable is constant.

Explanation:

In a normal line graph, there are generally two variables on two different axis one is at the x-axis and the other is on the y-axis that represents the correlation between these two variables. If there is a change in the variable present on the x-axis the change on the variable on the y-axis establishes the relationship among these variables.

If there is a period on the graph where the line is completely horizontal it means the variable present on Y-axis has no change during this period or is constant. Suppose a graph is plotted between speed or velocity on the Y-axis. A perfectly horizontal line on this graph means that speed is not changing over time and remain at te same speed.

1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?

Answers

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
