Almost all the energy and associated biomass in Earth's ecosystems comes from the
Sun. Which of the following is NOT true regarding energy transfer through an
ecosystem?
A
Decomposers recycle the matter contained by the dead biomass and waste and
make it available for use by producers and other consumers.
Ninety percent (90%) of the available energy is transferred from one trophic level
to the next. About 10 percent (10%) is lost to the atmosphere as heat.
с
Ecosystems sustain themselves by continuously cycling matter through the
trophic levels and capturing energy from the Sun or Earth and transferring it up
the food chain.
D
Energy flows from the Sun or from rocks through the primary producers and the
successive levels of consumers.
Answer:
D . Energy flows from the Sun or from rocks through the primary producers and the successive levels of consumers.
Explanation:
Energy flows only through the sun not the rock because sun is the ultimate source of energy which can be used by the plants for making their own food in the form of glucose during the process of photosynthesis. This plant is then eaten by primary consumer known as herbivore. These primary consumer is eaten by secondary consumer is called carnivores. The tertiary consumer feeds on the secondary consumer and so on. In the end, decomposers feed on the dead bodies of animals and releases nutrients which can be used again by the plants for making food.

how do the kidneys and the bladder work together??
Answer:
From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.
Explanation:
Although longitudinal waves can travel through all media types, what is the disadvantage of this type of wave transmission? Particles become too close together as they bump into each other making it more likely to hit other particles down the line. The waves travel in all directions which does not ensure that it will come into contact with particles down the line. The efficiency of the wave transmission is greatly diminished as the media becomes less dense. The oscillation of one set of particles has a huge impact on neighboring particles.
Answer:
The efficiency of the wave transmission is greatly diminished as the media becomes less dense.

C. Sublimation
STATION
D. Evaporation
3.
Answer:
1. D
2. B
3. A
Explanation:
The dashed circle indicates the process of infiltration because the water of precipitation goes inside the soil. Infiltration is the process in which water enters the soil through small opening present on the earth surface. When the clouds are formed, precipitation occurs in the form of rainfall and snowfall. Condensation is a process in which water vapors change into liquid when the environment has low temperature or cool so condensation occurs on the windows of Erica.
Describe an experiment to show that
Shoots are positively phototrophic.
Answer:
A well-watered potted plant is placed inside the box. If the window is kept closed for about 24 hours the plant shows normal growth. If the window is kept open, it is found after two days that the shoot tip bends and grows towards light proving that it is positively phototropic.

Pulmonary arteries transport ________.
A) oxygenated blood to the lungs
B) blood rich in carbon dioxide to the lungs
C) oxygenated blood to the heart
D) oxygenated blood directly to the aorta
No links or I'll report
Answer:
B
Explanation:
I would say this because the pulmonary circulation only transports deoxygenated blood. And this blood gets transported to the lungs so the lungs can absorb oxygen and release carbon dioxide. I am not sure about this one though. This is what I think.
Pulmonary arteries transport blood rich in carbon dioxide to the lungs also known as deoxygenated blood.
Blood Transportation:Arteries carry oxygenated blood in the body, and the pulmonary arteries carry deoxygenated blood to the lungs.The main pulmonary artery, or the pulmonary trunk, transports deoxygenated blood from the heart to the lungs.The main pulmonary artery branches into both a right and left vessel. The right pulmonary artery carries blood to the right lung. The left pulmonary artery carries it to the left lung.Thus, we can conclude that Pulmonary arteries transport deoxygenated blood from the heart to the lungs.

What would be the mRNA sequence?
What would be the amino acid sequence?
What would occur to the amino acid sequence if the following mutation (G --> C in bold below) were to take place?
DNA sequence 3' TAC GGG ACT CTT TCC ACT 5'
What type of mutation is this?
Explanation:
TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Can't see the bold :/
Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Insertion mutation.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

Scientists have observed that new crust, such as mid-ocean ridges, is formed where two plates are moving away from each other. Based on this observation and the data on the maps, where do you suspect that old crust is destroyed and recycled? Provide three specific locations on the map where you think this process is occurring
Answer:
Old crust is destroyed at boundaries where two plates are moving toward each other, or converging. Specific examples include the Australian and Pacific plates, the Caribbean and Cocos plates, and the southwest corner of the North American plate and the Pacific plate.
Explanation:
Having studied tectonics in school, Roberto grew interested in tectonic plates and how they move. Plates move in different ways along plate boundaries.

Explanation:
The kind of boundary and the directions in which the plates are moving determines how the plates interact at their boundaries. Therefore, option (D) is correct.
What is plate tectonic?There are two main categories of tectonic plate interactions: Divergent boundaries are places where plates separate from one another, creating rift valleys or mid-oceanic ridges. Additionally called as constructive borders, they are. Areas where plates move toward one another and clash are known as convergent borders.
The movement of plates, known as plate tectonics, has a significant influence on our globe even though they move extremely slowly. Mountains, continents, and seas are created by plate tectonics.
