Clastic sedimentary rocks are formed by fragments of rock that are  squeezed and cemented together. Answer A
mart [117]3 years ago

Answer:

The correct answer would be A.  Fragments of rock are squeezed and cemented together.

Clastic sedimentary rocks refer to the group of rocks formed by clasts or pieces of pre-existing rocks.

Four basic steps are involved in the formation of clastic sedimentary rocks:

  • Weathering: it causes the loosening of the rocks.
  • Transportation: sediment is carried along the currents to the depression or basin.
  • Deposition: sediments are deposited and trapped in the basin.
  • Compaction: sediments are compacted and cemented together and form a rock.

Chiasma form during meiosis I but not during mitosis. <br> a. True <br> b. False
Goryan [66]

Answer:

True

Explanation:

Chiasma is the site of crossing over. It is an X-shaped site that appears in a tetrad (bivalent) chromosome during the diplotene stage of prophase I of meiosis I. Crossing over refers to the exchange of segments of chromatids and occurs between homologous chromosomes only. Crossing over is the event of prophase I of meiosis I and produce new gene combinations.

The homologous chromosomes are separated from each other but remain attached at chiasmata. The dissolution of chiasmata occurs by the end of prophase I and separates the homologous chromosomes completely from each other. Crossing over does not occur in mitosis. Since mitosis does not include crossing over, chiasmata are also not formed in mitosis.

Diffusion, Osmosis and Enzymes
Nana76 [90]

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions - Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream -Simple Diffusion

d)Involved with, but does not become a part of chemical reactions -Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process- Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.

maks197457 [2]
Well, there's producers and consumers. There is also one provider that is the main source of energy for all living things which is the sun. The sun provides sunlight for the producers to make their own food through photosynthesis then consumers come and eat the producers(plants) and that gives them energy. And then predators come and eat that animal and that provides their energy.
