Explanation:
Solar radiation, or insolation, is the “fuel” of all solar energy systems. The performance of solar photovoltaic systems which generate electricity and solar thermal systems which produce hot water all depend on the availability and intensity of solar radiation.
In mature animals when do cells still need to differentiate?
Answer:
As an organism develops, cells differentiate to form different types of cells. Most types of animal cell differentiate at an early stage. Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement.
Explanation:
''.''
In mature animals cells differentiate during : Repair and replacement of animal cells
Cells differentiate in organisms and plants to create more cell types, as the organism and plants continue to mature. While cell differentiation in animals occur mostly before maturity, plants cells continue to differentiate until they die.
While in mature animals, cells differentiates at maturity only when the cells of the mature animal needs repair or replacement due to damage caused to the a cell or tissue.
Hence we can conclude that in mature animals cells differentiate during repair and replacement of cells.

NEED HELP WITH THESE 4 QUESTIONS WILL GIVE BRAINLIST!!!
1.What were some characteristics that the finches developed to give them an advantage in surviving?
2.How do you think that the one species of finch evolved into many different species, each with its own advantages?
3. In what ways do these advantages help the finches to survive and reproduce?
4. What might have happened if the finches didn't evolve into many different species?
Answer:
1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.
2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection
3. Medium ground finches with larger beaks could take advantage of alternate food
4. three species of Darwin's tree finches have been known to inhabit Floreana but no birds singing that song on Floreana have been heard in many years.

The diagram below compares the relative diameters of two planets in our solar system.
Which two planets have diameters that most closely resemble this comparison?
1.
Uranus and Neptune
2.
Jupiter and Saturn
3
Earth and Mars
4.
Mercury and Venus
Submit Answer
Answer:
1, uranus and neptune
Explanation:
i just did it
Based on the diagram above, the two planets having diameters that most closely resemble this comparison are: 1. Uranus and Neptune.
A solar system is an astronomical system which comprises both the inner and outer planets alongside celestial bodies such as a Moon, that are typically in orbit (traveling) around the Sun in slightly elliptical orbits..
Basically, the nine (9) planets that are found in the solar system orbiting around the sun include;
Mercury. Venus. Earth. Mars.Jupiter.Saturn.Uranus.Neptune.Pluto.Generally, the planets found in the solar system vary considerably in terms of shape and size as shown below:
1. Uranus and Neptune: the mean diameter of Uranus is 50,724 km (31,518.43 mi) while that of Neptune is 49,244 km (30598.8 mi).
2. Jupiter and Saturn: the mean diameter of Jupiter is 142,984 km (88,846 mi) while that of Saturn is 120,536 km (74897.6 mi).
3. Earth and Mars: the mean diameter of Earth is 12,756 km (7926 mi) while that of Mars is 6779 km (4212.275 mi).
4. Mercury and Venus: the mean diameter of Mercury is 4,879 km (3031.67 mi) while that of Venus is 12,104 km (7521 mi).
From the above data on diameter, we can deduce that both Uranus and Neptune are mostly related in terms of size as depicted in the diagram, by using two (2) circles of equal sizes.

What change to the following molecule's structure would result in a saturated fat?
Answer:
It needs to gain a Hydrogen atom to eliminate the double bond between the two carbons.
Explanation:
Unsaturated fat has one or more double bonds in its molecule. Saturated fat has a single bond. If you want an unsaturated fat to become saturated it needs to gain more more hydrogen atoms which will eliminate the double bonds between carbons of the unsaturated fat.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.
