Answer:

<u>D) melting and soliditation​</u>

Explanation:

Granite is a type of grainy (medium-coarse) igneous rock. These are formed from quartz, alkali feldspar and trace minerals along with plagioclase. Rocks like quartz, form a crystal from magma or as a precipitate near hydrothermal vents.

A type of intrusive igneous rock, granite is formed from its constituents when it molten rock cooled. Larger mineral crystals are associated with slower cooling over time.

beks73 [17]

Answer:

The correct answer will be-gas absent in primordial atmosphere (oxygen).

Explanation:

The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.

Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.

Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.

Within a gymnosperm megasporangium, which of the following developmental sequences is correct, assuming fertilization occurs? Gr
yan [13]

Within a gymnosperm megasporangium, the following developmental sequences that are correct, assuming fertilization occurs is: megaspore, female gametophyte, egg cell, sporophyte embryo. The last Option (Option D) is correct.

In gymnosperm megasporangium, the meiotic division produces four haploid megaspores from a single cell, three of which generally degenerate. The female gametophyte is formed by mitosis from the surviving megaspore.

Prior to fertilization, the male mature gametophyte needs to be transferred to the female gametophyte for fertilization to take place.

When the nuclei of the sperm encounter the nucleus of the egg cell in gymnosperms, it fuses with the egg nucleus to produce a diploid zygote.

Mitosis occurs in the fertilized egg to initiate the growth of a new sporophyte generation (the multicellular embryo of the seed.)

Therefore, we can conclude that we've understood the mechanism of developmental sequence in the gymnosperm megasporangium.

Select the best description of amino acid metabolism: Group of answer choices Amino acid metabolism does not occur. Aerobic meta
Stolb23 [73]

Answer:

Aerobic metabolism of amino acid requires deamination

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, digestion, metabolism, etc.

Metabolism can be defined as a set of chemical processes carried out by a living organism such as humans, plants and animals, in order to sustain life.

Aerobic (oxygen-using) metabolism can be defined as a biological process that typically involves the extraction of energy from any carbohydrate source such as amino acids, fatty acids, etc.

Basically, an aerobic metabolism of amino acid is a process that requires deamination.

Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.

Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.

Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.
