Oduvanchick [21]1 year ago

The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.

  • The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
  • With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
  • All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
  • While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____.
Nonamiya [84]

Answer:

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called  ____

The answer is "dorsal root ganglia"

Explanation:

Explanations of some terms

Sensory neurons:

Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as  spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.

Spinal cord:

The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.

Dorsal root ganglia:

Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?
Degger [83]

Answer:

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?

Acceleration= velocity/time

velocity=5mm= 0.005m

time= 1 hour= 60 seconds

A= 0.005/60

Acceleration= 0.000083m/s square

Which two structures are found ONLY in plant cells?
Naya [18.7K]


The best answer is  C.

Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.

The cell wall is  a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant  cell wall.

Chloroplasts are plant  cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
