Which of the following is a value of biodiversity?

How does the longest stage of cell division stated above play a role for growth of plant

wariber [46]

Answer:

During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase. In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met.

Electrophysiological studies of rats learning T-mazes have found _________.a. different patterns of activation in the basal gang

Solnce55 [7]

Electrophysiological studies of rats learning T-mazes have found a. different patterns of activation in the basal ganglia during early learning and later stable performance

Explanation:

Forced alternation and left-right discrimination tasks using the T-maze have been widely used to assess working and reference memory, respectively, in rodents.
Basal ganglia are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas. The basal ganglia are associated with a variety of functions, including control of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.
The direct pathway, sometimes known as the direct pathway of movement, is a neural pathway within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement.
Damage to the basal ganglia cells may cause problems controlling speech, movement, and posture. This combination of symptoms is called parkinsonism. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement.

A nerve is a bundled unit of nerve fibers located ________ the brain and spinal cord, connecting various parts of the body.

Nadusha1986 [10]

A nerve is a bundled unit of nerve fibers located in the ide peripheral nervous system of the brain and spinal cord, connecting various parts of the body. These are the axons and are cable-like bundles which provide a way for all the electrochemical signals. They are of 3 types: afferent, efferent and mixed nerves.

Most organisms can be divided into two categories - prokaryotes and eukaryotes. What is the main difference between these two ca

Klio2033 [76]

Answer:

The main difference between Prokaryotic and Eukaryotic cell is that, eukaryotes contain membrane bound organelles like nucleus where as prokaryotes do not. The genetic material is present at the center and is called nucleoid in prokaryotes.

Explanation:

Example of prokaryotes include bacteria and archea bacteria. Examples of eukaryotes include plants and animals. Prokaryotes lack organelles such as mitochondria, endoplasmic resticulum and lysosomes which are present in eukaryotes. Both the groups contain ribosomes but its 70s ribosome in prokaryotes and 80s ribosomes in eukaryotes.
