Why can a macroscopic amount of liquid that is contained change with the shape of the solid container holding it?

Biology
1 answer:
GaryK [48]3 years ago
4 0

Answer:

C. Liquid molecules and atoms are able to slip around each other and fill in gaps between them.

Explanation:

The liquid is a state of matter that has no definite shape. In fact, it can adapt to the shape of its container. This is because of the reason that molecules in the liquid phase have high kinetic energy and weak binding forces. The high energy keeps them moving freely and thus can take the shape of it its container. On the other hand, in solids, the binding forces are stronger and molecules have very little energy to move freely.

Example: If we melt a solid, the molecules initially have less energy. However, when we heat them, they gain energy and start moving. Upon further heating, they will have enough energy to break the bondings and move around. This is why the solid structure will change to the liquid.

In animals, carbon dioxide waste is exchanged for
LUCKY_DIMON [66]

Answer:

oxygen

Explanation:

  • Through the process of respiration , in lung the carbon dioxide from the blood is exchanged with oxygen.
  • The smallest dunctional unit if the lung is the alveoli
  • At this level the gases are exchange through the capillaries present close to the alveoli.
  • The concentration gradient ,meaning the greater amount of oxygen present in the lungs and greater amount of carbon dioxide in the blood creates a gradient that allow the movment of oxygen into the blood and carbon dioxide in the alveoli through the membrane .
  • Partial pressure created allows the easy movement .The carbon dioxide get into the trachea and expelled through nose and mouth.

At a basic level mitosis and meiosis are similar processes. However, they have very different outcomes. Which of the following s
Dafna1 [17]

Answer: C. Homologous chromosomes are separated in meiosis but not in mitosis.

Explanation: There are two main types of division that take place in eukaryotic cells, mitosis, and meiosis. Mitosis is the type of division that is used for growth, repair, and replacement of tissues. Therefore it is not necessary that the cells have  different chromosome numbers or are varied genetically in the daughter cells in the case of mitosis.

Meiosis is the division that takes place to form the gametes for sexual reproduction. It is important in the first stages of meiosis I, to introduce variation and to halve the chromosome number.

Chromosomes numbers are halved (from 46 to 23) during meiosis I because the gametes (sperm and egg) come together and fuse during fertilization to form a zygote. When this fusion occurs (23 from the zygote and 23 from the egg), the chromosome number needs to be returned to that of the parent cell (46).

<h2>Genetic variation is introduced during synapsis which only occurs in meiosis, not mitosis. Homologs exchange genetic information during crossing over of synapsis. Entire chromosomes also separate during meiosis I. </h2>

At the end of meiosis, four genetically unique cells are  produced with half the number of chromosomes as the parent cell (23 cromosomes) . After the process of mitosis is completed, two cells genetically identical to each pther are produced and have the same number of chromosomes as the parent cell (46 cromosomes).

Genetic variation is actually important because of changing environmental conditions.
