Answer:
The NBTs focus on academic readiness for university study. Each test requires you to apply prior learning - what you know and are able to do - to materials that reflect expectations for first year students in university programme
Answer:
(D) mutant
Explanation:
Translation occurs at the ribosome, which consists of rRNA and proteins. ... Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein. A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Motor neurons are cells that carry information from the central nervous system to the muscles and glands, while sensory neurons send signals from body parts to the central nervous system. Sensory neurons are found over the body, such as in the skin, ears, eyes, nose and tongue. Interneurons in the central nervous system allow information to flow between motor and sensory neurons.
he cell body of a neuron holds a nucleus and organelles that carry out basic cell functions, such as protein synthesis, transporting materials and producing energy. A neuron also has special parts that allow information to move. Dendrites are branch-like structures that receive signals. The axon, which often resembles a long tail, takes messages away from the cell. The axon ends in a terminal containing a chemical called a neurotransmitter, which allows the signal to move across the space between the cell that sends information and the cell that receives it. When axons and dendrites of different cells are bunched together, they create nerves. Ganglia are groupings of many neurons' cell bodies.
The processes conducted by nerve cells happen incredibly fast, in thousandths of a second. That is why the human body reacts so quickly to stimuli in the environment. A hand touching a hot stove is removed almost immediately so that serious injury does not occur.

Answer:
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
