Answer:
E) Binary fission
Explanation:
Bacteria can simply divide by binary fission, an asexual reprodution where single bacterial body separates into two bodies. During this process bacteria duplicates its DNA content so that when the body separates by cytokinesis, each has its own DNA material.
Hand to hand or hand over hand is recommended to maintain vehicle balance.
Answer:
The Central Nervous system is made up of the brain,the control units,and the spinal cord ,the network of nerves ,which feed the brain with sensory information for processing.The entire CNS is lined by a constantly circulating fluid called the Cerebrospinal Fluid.(CSF).
Together with the Peripheral Nervous system,the CNS ensure coordination of the body activities.
Generally both the brain and the spinal cord are protected by the skull and vertebral column respectively. Their activities are based on the million of neurons which are networked by synapses.
Functions are:
processing information that is received from the stimuli receptors
sending out information so that the body can react appropriately to stimuli
coordinating reflexes and reactions to stimuli.
These functions are performed through the fast reflex pathways, for efficient coordination of the systems of the body by the CNS with PNS
Explanation:
1. The domains of the evolutionary biology and the biotechnology are linked to each other. The work of a bio-technologist requires him to have the knowledge of evolutionary biology, as a bio-technologist improve the already existing organisms. The evolution has led to the selection of the most useful features in different organisms, such as the restriction enzymes, which are used by bio-technologists to cut the DNA at specific paces for their research. These enzymes were originally present in the bacteria as a defense mechanism against the viruses. The knowledge of this evolutionary feature in the bacteria was necessary for a bio-technologist so that he can use it for further research.
2. The most crucial ethical issue involved with the biotechnological research is the use of living organisms. The biotechnology research involves the modification of the living organisms at a genetic level, which is not always successful. The issues related to the research that the bio-technologists alter with the natural path of the living organisms is the major ethical concern.
Answer:
here!!
Explanation:
oxygen = exocytosis
water molecules = osmosis
charged amino acid = simple diffusion
calcium move from low concentration to high concentration = active transport
protein from the Golgi apparatus = carrier protein
