How does energy flow in an ecosystem
Answers
Answer:
Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.Hope this helps you !!

Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms
Answers
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.
Explanation:
Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.
What are analogous structures?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.
While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).
Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

DNA ___________ is important because it ensures that when a cell divides, the two resulting cells have the same genetic code. Pleaseee help
Answers
Answer: Replication
Explanation: When the cell is preparing to divide it will replicate its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)

what experiments led to the discovery of dna as the hereditary material?
Answers
Answer:
In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

function of nucleus, mitochondria ,endoplasmic reticulum, vacuoles
Answers
Answer:
nucleus...controls all the activities of the cell and carrries the genes
mitochondria..site for respiration that yields energy for the cell
endoplasmic reticulum... protein synthesis and lipids metabolism
vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also
Explanation:
is this helpful?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

Answers
Uracil is a nitrogenous base found in all RNA but not present in DNA. There are multiple unusual modified bases found in tRNAs not found in DNA as well: Dihydrouridine, Pseudouridine, 1-methyl adenosine, N2,N2-dimethylguanosine, inosine, and 1-methyl-inosine. There are other nitrogenous bases that are metabolic intermediates that are not found in nucleic acids such as inosine (also in tarna), hypoxanthine, xanthine, dihydroorotate, orotate, and the purine break down product uric acid.

Why is air temperature above land warmer than the air temperature above water in the same location during the summer?
Answers
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

exchange of gases in the human breathing system takes place in the?
Answers
alveoli
ExplanationDuring gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The exchange of gases takes place in the alveoli.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Additional information :- Alveoli are microscopic air sacs. They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(86°F) with sunny skies?
A. 34°C (94°F) with cloudy skies
B. 30°C (86°F) with cloudy skies
C. 22°C (86°F) with sunny skies
D. 32°C (90°F) with sunny skies
Answers
Answer:
B
Explanation:
jus CS its right
The relative humidity of the air affects how much water vapor it can hold. 30°C (86°F) with cloudy skies would air hold less water vapor than it holds at 30°C (86°F) with sunny skies. So, the correct option is B.
What is Relative humidity?Relative humidity (RH) measures the amount of moisture in the air compared to the maximum amount of moisture in the air at a given temperature and pressure. It is a standard figure for describing the moisture content of the air and is expressed as a percentage.
At a given temperature and pressure, air is considered to have 100% relative humidity when it contains all the moisture it can hold. The temperature at which the moisture in the air begins to condense into droplets is known as the dew point.
Therefore, the correct option is B.

How does your body respond to a decrease in blood glucose

Answer:
When blood sugar drops too low, the level of insulin declines and and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal
