The nucleotide sequence of a strand of DNA TAC -CGG-AGTWhat the amino acid sequence of the resulting protein ?
The amino acid sequence would be "Met-Ala-Ser."
What is a nucleotide sequence?A nucleotide sequence is a linear arrangement of nucleotides, the building blocks of nucleic acids such as DNA and RNA. Nucleotides are composed of a nitrogenous base, a sugar molecule, and a phosphate group. There are four different nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U).
The specific order of these nitrogenous bases in a DNA or RNA molecule encodes genetic information, which is used by cells to carry out various functions such as protein synthesis. The nucleotide sequence determines the structure and function of a nucleic acid molecule and plays a crucial role in the processes of heredity and evolution. The study of nucleotide sequences and their function is a central part of the field of molecular biology and genomics.

List 2 organelles found in an animal cell and explain how those 2 organelles benefit the cell.
Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.
What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
Thus, these were explanation of two cell organelles along with their explanation.

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles
Answer:
The correct answer is - increase: constriction of the arterioles.
Explanation:
When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.
It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

If the difficulty arises from a defect in one particular area of the nervous system, which area is most likely to be involved
Answer:
Basal Ganglia
Explanation:
The Basal ganglia function is to regulate the voluntary movements or autonomic movement. This is done by receiving and transmission of impulses. Impulses are received for upcoming movement from the cerebral cortex and then process and adjust from where it is convey to the thalamus which then relays this information back to the cortex. The well defined movement instruction is finally sent to the skeletal muscles through the tracts of the pyramidal motor system. It also function in planning and modulation of movement, memory and eye movement.
There are five types of basal ganglia corpus striatum, claustrum, amygdala, substantia nigra and subthalamic sails which all function together.
