are corks prokaryotic or eukaryotic cells?​

Answers

Answer:

Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

Comparison of Eukaryotes vs. Prokaryotes. Play media. 3D animation of aprokaryotic cell that shows all the elements that compose it. A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organelle.

A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota

Explanation:

Corks are a type of plant part that is eukaryotic cell having well developed nucleus.

What are corks?

Cork cells are dead cells found in the bark of stems. They appear hexagonal or pentagonal under a microscope. In 1665, Robert Hook used a microscope for the first time to examine cork cells.

Plant cells that mature into mature cork cells form the protective water-resistant tissue in the outer covering of stems or trunks.

Cork cells are genetically programmed not to divide and, as a result, are considered dead cells.

Eukaryotes are organisms with nuclei and other membrane-bound organelles. Eukaryotic organisms include all animals, plants, fungi, and protists, as well as the majority of algae.

Thus, it can be concluded that the corks are eukaryotic cells.

From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere. Oxygen was a toxic compound to most life forms from that time period. Today, oxygen is required by all but some of the most primitive life forms. Which statement best explains how early life forms that were harmed by oxygen evolved into today's life forms that require it?

Answers

Answer:

C

Explanation:

Over time, many species gradually adapted to a more oxygen-rich environment, allowing them to survive in shallow water and on land.

From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere, but the early life forms were harmed by the gas, and later those who survived passed on their genes to the next generation through evolution.

What is the significance of oxygen in evolution?

Evolution is a process that explains life's ability to adapt and change over time in response to environmental conditions and the process of evolution is one of the central mechanisms driving life's diversity, but the presence of oxygen harmed early life. As life forms evolve, oxygen becomes one of their most important gases.

What will happen to this cell?
A) it will shrink
B) nothing
C) it will explode

Answers

The cell shown in the image is placed in a solution of  0.5 M whereas the internal concentration of the cell is 0.1 M, hence the solution is hypertonic and the cell will shrink.

The correct option is A.

What is a hypertonic solution?

A hypertonic solution is a solution with a higher concentration of solutes (e.g. salt, sugar, or other molecules) compared to another solution.

When a cell is placed in a hypertonic solution, water molecules will move out of the cell and into the surrounding solution, which can cause the cell to shrink or even collapse. This is because the concentration of solutes inside the cell is lower than that of the hypertonic solution, so water diffuses out of the cell in an attempt to balance the concentration on both sides of the cell membrane.

Imagine you accidently step on a sharp object with

Explain how the parts of the peripheral nervous
system work with the central nervous system to
produce a response to the stimulus

Answers

Answer: receptors in the skin stimulate sensory neurons

Sensory neurons send messages to the central nervous system

Interneurons send messages to the motor neurons in response to messages received from sensory neurons

Motor neurons cause muscles in the leg to contract and pull the foot away

Explanation:

To produce a response to the stimulus, receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment and from inside your body.

How peripheral nervous system works with the CNS?

To produce a response to the stimulus the central nervous system processes information, it is the information that is received from the peripheral nervous system.

After that, the central nervous system sends this processed information to the peripheral nervous system. The peripheral nervous system sends a signal to the body part that needs to respond so you can react appropriately to the stimulus.

Therefore, if you accidentally step on a sharp object with your bare foot the peripheral nervous system work with the central nervous system to produce a response to the stimulus through receptors.
