Answer:
Central nervous system includes brain and spinal cord. Peripheral nervous system includes autonomic nervous system and somatic nervous system.
Explanation:
Nervous system consists of electrically excitable cell called neurons and collection of nerves that transmit information in the body.
Nervous system is mainly divided into two parts - PNS (peripheral nervous system) and Central nervous system (CNS) . The CNS of the body consists of spinal cord and brain that regulates and coordinates all the functions of the body.
PNS consist of cranial and spinal nerves. This system is divided into Autonomic nervous system ( controls involuntary actions of body) and somatic nervous system ( control the voluntary actions of the body).
Answer:
Eukaryotes
Explanation:
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
Answer:
Budding cells formed by the Saccharomyces are through "Cytokinensis"
Explanation:
Cytokinensis helps the budding cells of the Saccharomyces to get splitted over two new cells. These buds raise, throughout its cell cycle and afterwards leaves its mother cell while mitosis been completed. Budding of the yeast makes up an perfect model for the creature to study the meiosis. Diploid yeast can be prepared by making it undergo through meiosis in absence of nitrogen which will lead to the generation of an ascus along with 4 haploid cells. Due to this the property of the meiotic products can also be studied.
D. The repressor is freed from the operator when lactose is present.
Think of a bacteria that comes into contact with some lactose sugar in milk. Normally it's not in milk, so the gene is repressed (prevented) from making the lac enzyme (which digests lactose). Now when it comes across some milk, it wants to make as much lac as possible to eat up all the lactose.
FYI: trp for tryptophan works the exact opposite with repressor blocking when trp IS PRESENT.
