Scientists detect their effect on the matter nearby, say if a normal star passes near a black hole, the black hole will pull it towards itself tearing it apart, as the attracted matter accelerates it emits x-rays that radiate in space till it reaches the Earth.

We can infer the presence of black holes and study them by detecting their effect on matter nearby.

Describe how you could use a globe and your hand to model the path of a global convection current in the atmosphere.
mash [69]

Answer and Explanation:

The process of transmission of heat due to the movement of molecules in the fluid is called convection. Convection also takes place on a global scale. At the equator, warm and less dense air tends to flow and rise towards the poles. Then denser, cooler air sinks and flow back towards the poles. Due to the rotation of earth rising warm air from the poles does not make it all the mode towards the pole. The combination of the earth’s rotation and global convection makes a series of wind patterns known as convection cells. The earth's rotation also alters the airflow pathway, which causes the wind’s path to be curved as it travels between the equator and poles. In the southern hemisphere, winds turn to the left and move anticlockwise around a high-pressure centre, while in the northern hemisphere, winds turn to the right and move clockwise around a high-pressure centre. The twisting of air currents, due to the rotation of the earth is termed as Coriolis effect. Due to this effect, winds turn to the left in the southern hemisphere. In the northern hemisphere, winds turn to the right.

A change in the nucleotide sequence of a gene can lead to a change in _______, which can lead to a change in in the amino acid s
Julli [10]

Answer:

Codon transcription

Explanation:

The DNA, present in the nucleus, is the stored form of the genetic material i.e. a segment of it is called a gene. DNA is one of the two types of Nucleic acids made up of nucleotide sequences. A nucleotide is a combination of a five-carbon sugar (Deoxyribose in DNA), nitrogenous base and a phosphate group. These nucleotides are arranged in sequence to form the nucleic acid (DNA or RNA).

The information stored in this gene has to be expressed, and this is done via transcription and translation processes.

Transcription is the transfer of genetic instructions in DNA to mRNA. In transcription, a strand of mRNA that is complementary to a strand of DNA is formed. Transcription occurs in three steps viz: Initiation, elongation and termination where RNA polymerase uses sequence of bases in DNA to make a complementary strand of mRNA. The mRNA undergoes additional processing including spicing, editing and polyadenylation before it leaves the nucleus to the ribosome for protein synthesis.

Each three successive nucleotide base stretch of mRNA is known as CODON and each coding contains information for a specific amino acid. These codons direct protein synthesis with assistance of tRNA in a process called translation.

In translation, the mRNA sequence is used as a template to assemble, in order, the chain of amino acids that form a protein.

If there is a change in the nucleotide sequence in the gene (segment of DNA), it will lead to a change in the sequence of the three-base mRNA (codon) formed, which may ultimately cause a change in sequence of amino acids (proteins)
