Explain Hertzspeung-Russell diagram relationship to stars life cycles

Answers

Answer 1
The sun provides a handy benchmark for describing other stars. The mass of this solar system's sun gives us a unit for measuring other stars' masses. Similarly, the sun's luminosity and surface temperature define the center of the Hertzsprung-Russell Diagram (H-R Diagram). Plotting a star on this chart reliably predicts other qualities of the star, such as mass and age. The main sequence phase of a star's life cycle is that time during which hydrogen fusion takes place in its core. But in terms of the H-R Diagram, "main sequence" also refers to a roughly diagonal, slightly S-curved line stretching between the upper-left and lower-right corners on which main sequence stars chart. They maintain a predictable relationship between luminosity and temperature: the brighter, the hotter. Both of these traits increase with a star's mass; a star indicated closer to the upper-left corner will be "heavier" than our sun, while lower-right main sequence stars will be "lighter."

Red Giants

Should astronomers plot a newly discovered star in the upper-right corner of the H-R Diagram, being both bright yet cool, they'll immediately know what phase of its life cycle the star is enduring. A red giant's core, hot enough to fuse helium and even heavier elements, has pushed its shell layers so far out that they can cool into the red spectrum. They owe their great luminosity not to their temperature, but to their size: bigger stars radiate more light energy.

During cytokinesis plant cells form a cell plate instead of pinching apart like an animal cell, propose a reason why there is this difference.

Answers

Options are not given in the question. So, the complete question is as follows:

During cytokinesis plant cells form a cell plate instead of pinching apart like an animal cell, propose a reason why there is this difference.

A. The plant cells do not contain centrioles do they cannot pinch apart

B. Plant cells have rigid cell walls so they form a cell plate instead of pinching apart.

C. Plant cells do not divide as rapidly as animal cells

D. In plant cells the large central vacuole prevents the cell from pinching apart.

Answer:

B. Plant cells have rigid cell walls so they form a cell plate instead of pinching apart.

Explanation:

Plant cells and animals cell are somehow different from each other in their structure as well as in functions such as plant cells form a cell plate while animals cells, pinching apart the cells during cytokinesis.

This difference is because plant cells have rigid cell walls that form a cell plate unlike complex cells like animals that being pinch into halves.

Hence, the correct option is "B".

Answer:

Plant cells have rigid cell walls so they form a cell plate instead of pinching apart.

Answers

Answer:

a domain

Explanation:

The domains are the basic units of the proteins, they are polypeptide segments (about 30 -200 amino acids) that have a defined tertiary structure and play specific biological functions including, for example, enzymatic and structural activities. Protein domains are evolutionary conserved, it means that these polypeptide segments can be found in phylogenetically related species and share sequence homology. Examples of protein domains include the zinc finger and the helix-turn-helix domains which are involved in protein-DNA interactions of transcription factors.

Answer:

Explanation:

...then the bird beak changes because the bird beaks are the most vital physical feature that allows birds to catch and devous its prey.

Answer:

then... the frequency of different types of bird beaks will change, because... birds with beaks that are more suited to the available food are more adapted and will be more successful over time.

Explanation:

This is linked with natural selection.

If the type of the food available changes, then the frequency of different types of bird beaks will change, because birds with beaks that are more suited to the available food are more adapted and will be more successful over time.

Evolution of beak types will be a result of the birds adapting and changing their food habits. Natural selection is the process where organisms adapt and change.

Asthma is a respiratory disorder that can cause the airways to temporarily constrict, or get narrower. Which function of the respiratory system is most affected by the narrowing of the airways? A. water balance B. air filtration C. heat balance D. gas exchange

Answers

Answer:

Answer is D.

Explanation:

Asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.

What is asthma?

It is a chronic disease of the lungs that inflames and narrows the airways.

Since this disease causes the airways to become inflamed and swollen, it reduces the amount of air that can move in and out of the lungs (gas exchange).

Therefore, we can conclude that asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.

A student draws this model to show how humans evolved from ancestral primates. What are the pros and cons of
this model in regard to the theory of evolution? Explain how you'd make it more accurate. To create a scientifically
credible answer, use a credible website to research human evolution.​

Answers

Answer and explanation:

The model designed by the student is useful to explain in a simple way the question of the evolution of the homo gender (our gender), mainly in basic education, but it may seem inconsistent at higher educational levels.

Humans and chimpanzees, according to the theory of evolution, descend from a relatively recent (about 7 million years) common ancestor.

These same species, as well as lemurs, baboons and all other primate species, share an ancestor who lived longer.  Likewise, there is an even older ancestor that originated primates, bats, whales and all other groups of mammals .

The fact that chimpanzees have a DNA very similar to ours (about 98.5% similarity between code sequences) is because the successive evolutions from this common ancestor were not very drastic, besides the fact that they are in a branch more close to ours from the moment of separation of evolutionary lineages.

How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.

Answers

Answer:

Population of some organisms increases and some decreases with the increase in temperature.

Explanation:

The population of certain species such as Nassuar grouper, Spotlight parrotfish and Queen angelfish increases with the increase in temperature while some species such as yellow tail snapper, sponges and algae decreased in population with the increases in temperature. This is because some species needs high temperature so increase in temperature increases the population while some species needs low temperature so high temperature kill them and population is decreased.

Answer:

The population of some creatures increases while the population of others falls as the temperature rises. Certain species, such as Nassuar grouper, Spotlight parrotfish, and Queen angelfish, see an increase in population as the temperature rises, whereas others, such as yellow tail snapper, sponges, and algae, see a fall in population as the temperature rises. This is because some species require high temperatures, so a rise in temperature increases their number, but others require low temperatures, so an increase in temperature kills them and decreases their population.

Answers

Answer:

The correct answer is proteins.

Explanation:

The exotoxins are proteinaceous in nature, they are the toxins, which are discharged from a living bacterium and are also discharged at the time of bacterial lysis. The exotoxins harm humans, however, not all exotoxins generated harm human beings.  

Some are even created to perform an essential function in bacteria physiology like regulating functions of the cell, resisting bacteriophages, or quorum sensing. The three prime kinds of exotoxins are type I exotoxins or superantigens, type II toxins or exotoxins that damage host cell membranes, and type III toxins or A-B toxins that interfere with the function of the host cell.

Which substance's cycle can be disrupted by the addition of fertilizer and can result in eutrophication?

nitrogen
water
oxygen
carbon

Answers

Answer:

Oxygen

Explanation:

When excessive minerals(N.P.K) and nutrient are released into the body of water from leaching and other sources,(detergents,fertilizers application,sewage etc )which leads to  corresponding increase in the population of algae(algae boom)the condition is called Eutrophication.

This disrupts the oxygen cycle because,the increased algae population(algae boom) makes use of available oxygen in the habitat for respiration.With continue supply of the  nutrients,the population continue to rise.The competition for oxygen with other fauna leads to shortage of available oxygen,and therefore death of these fauna,and later of the algae.

The decomposing bacteria,also used the fragment pf oxygen to decompose the algae and other dead fauna,further reducing the oxygen levels of the water,with increase in water pollution.

Answer:
