The controlled process by which hydrocarbons are broken down or re-arranged into smaller, more useful molecules is called Cracking. The process allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Cracking may be done using heat energy (thermal cracking) or using a catalyst (catalytic cracking). Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst, thus breaking chemical bonds in the molecules and forms smaller hydrocarbon molecules.

Who was responsible for "cracking the code" of DNA by establishing what amino acids are coded for by which codons, and when was
Akimi4 [234]

Answer:

The correct answer is- Nirenberg and Heinrich, 1961.

Explanation:

Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.

Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are  UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.

Which statement regarding Bax and Bak, two members of the Bcl-2 family, is true?
vampirchik [111]

Answer:

Option D When activated, Bax and Bak form oligomers in the outer membrane of mitochondria, leading to the release of cytochrome c.

Explanation:

The proapoptotic genes are involved in the process of apoptosis. The antiapoptotic gene prevents apoptosis that is cell death. The proapoptotic genes are bax, bak, bad and bid. The bcl family genes are antiapoptotic genes. The process involved activation of apoptosis inside the cell is called intrinsic pathway of apoptosis.

The activation proapoptotic genes, Bax and Bak form oligomers in the mitochondria outer membrane. These pores in the mitochondrial membrane allows the release of cytochrome-c that further attaches with Apaf-1. This leads to activation of caspase 9 that further activates caspase 3, thus inducing apoptosis.

Which neural pathway carries crude information about a threatening stimulus and activates a rapid instinctual alarm response?
Olin [163]

The correct answer is

B. the thalamus→amygdala pathway

The neural pathway carries crude information about a threatening stimulus and activates a rapid instinctual alarm response is the thalamus→amygdala pathway

The thalamus→amygdala pathway is also known as the the path of fear. The thalamus transfers signal to other parts of the brain that causes the release of adrenaline and stress hormones.
