Why is it relatively rare to observe a solar eclipse

Biology
1 answer:
Jlenok [28]3 years ago
3 0
A solar eclipse happens when the moon moves between the sun and earth casting a shadow on the earth.  Since the moon is small in comparison to the earth, the shadow cast only covers part of the surface area of the earth.  You have to be in the right place to see the eclipse because of the narrow path of the shadow.

Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

Explanation:

Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.

Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.  

Therefore bacteria do not undergo meiosis or mitosis.

Describe hydrogen bonding
snow_tiger [21]

A hydrogen bond is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. This is not a sharing of electrons, as in a covalent bond. Instead, this is an attraction between the positive and negative poles of charged atoms.

Can someone pls… im so close to being done
likoan [24]

Answer:

Because liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it is in.

Leokris [45]

Answer: Difficulty with communication

Explanation: The cerebral cortex is the thin layer of the brain that covers the outer portion (1.6mm to 5mm) of the cerebrum. It is covered by the meninges and often referred to as gray thing . The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex also covers the cerebellum.

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and <em><u>speech</u></em>, resulting in smooth and balanced muscular activity

How might a carbon atom from a orange peel in a trash can for a week, end up in an animal's lungs? (Think of how during cellular
defon

Answer:

An orange peel in a trash will start to decompose.

  • The carbon atoms will be released into the air as a result of decomposition.

  • These carbon atoms will be converted into carbon dioxide in the atmosphere.

  • Plants will take in this carbon dioxide for making food by the process of photosynthesis.

  • When animals will consume the pants, the carbon products will be accumulated int he body of the animals. Some of the carbon will be converted into carbon dioxide in the animals and will pass out of the animal's body through respiration.
