Answer:
Accordingly, when our Sun comes up short on hydrogen fuel, it will grow to end up a red monster, puff off its external layers, and after that settle down as a minimal white small star, at that point gradually chilling off for trillions of years. All incredible, in the long run — in around 5 billion years — our sun will, as well. When its supply of hydrogen is depleted, the last, sensational phases of its life will unfurl, as our host star extends to wind up a red Goliath and afterward shreds its body to consolidate into a white smaller person Explanation:

suggest a reason why termites have no eyes
Answer:
the pests have antennae covered with moisture-sensing receptors
Explanation:
Answer:
Many species of termites need to find areas of vegetation with plenty of moisture to survive. To get around their lack of vision, the pests have antennae covered with moisture-sensing receptors.They also have eyes but their wings do not develop further. These develop into the neotenics (see below), which are one of the reproductive types and have the ability to produce eggs in the colony in certain situations

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on dividing cells
The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

The work of such researchers as Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was somewhat similar to the predictions made by ________.
The work of Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was similar to predictions made by phrenologists. Phrenology is a pseudoscience.
Phrenology is a pseudoscience aimed at measuring bumps on the skull to predict personality traits.
Eduard Hitzig and Gustav Fritsch demonstrated that electrical stimulation of specific areas of the cerebral cortex could trigger movement.
Broca's area is an area located in the frontal part of the left brain hemisphere discovered by Paul Broca, who observed how this area has a fundamental function for the generation of speech in humans.
Finally, David Ferrier was a neurologist who discovered a series of motor fields within the cerebral cortex of monkeys.

Seawater has many different gases dissolved in it, specially nitrogen, carbon dioxide and oxygen. It exchanges these gases with the atmosphere to keep a balance between the ocean and the atmosphere.
What is atmosphere?An atmosphere is defined as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.
Dissolved oxygen and carbon dioxide are important for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis.
Cold water holds more gas than warm water and seawater with low salinity holds more gas than high salinity water. Deep water, that has a high pressure, holds more gas than shallow water.

Answer:
Elements are pure substances with only one type of atom
Explanation:
Elements are pure substances with only one type of atom
Answer:
There are more substances on Earth than are listed on the periodic table of elements because substances are combinations of the elements. Elements are pure substances with only one type of atom. When two or more elements are combined, compounds are formed. This allows more substances to be created on Earth.

Answer:

Answer:
Option 3.
totipotent stem cells → pluripotent stem cells → multipotent stem cells → neuron
Explanation:
The development of the various stages of stem cells in the embryonic stage is described here:Totipotent stem cells: Right after the mitosis of the zygote which results in the formation of two identical daughter cells, which are totipotent stem cells. Totipotent stem cells possess the ability to give rise to 220 different types of cells in the embryo including the placenta.Pluriopotent stem cells: These types of cells possess the ability to change into any type of cell in the body like blood, muscle, etc. It is formed at the embryonic stem cell stage.Multipotent stem cells: These stem cells have the ability to change into specialized cell such as forming different organs in the body. It occurs as the pluriopotent cell develops in the embryo.Neuron: As the multipotent cell has the ability to form a specialised cell it gives rise to the heart, lungs, liver, etc. including neurons.for more information:

Given the number of blood vessels in the retina, why do you suppose that you are not able to see them normally
Answer:
You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.
