Answer:
eukaryotic plant cell
hope this helps
Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.
Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.
Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.
The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.
So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.

how the function of the basal cells depends on the relationship among its parts?(respiratory system )
Answer:
Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.
Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.
The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.

One of the roles of ecological succession is to encourage biodiversity in a habitat. Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat A)is destroyed B)remains the same C)undergoes change D)is relocated
Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat undergoes change. Thus C is the correct option.
What is ecological succession?Ecological succession is defined as the process through which the mix of species and habitat in an area changes over time. Gradually these communities replace one another until a climax community like a mature forest is reached, or until a disturbance, like a fire, occurs.
There are two major types of ecological succession namely primary succession and secondary succession. Primary succession occurs when a new patch of land is formed or exposed for the first time.
Secondary succession occurs when a climax community or intermediate community is impacted by a disturbance.

1. A rock sample has a mass of 16 grams:
and a volume of 8 cubic centimeters.
When the rock is cut in half, what is
the volume and density of each piece?
(1) 8 cm3 and 0.5 g/cm3
(2) 8 cm² and 1.0 g/cm3
(3) 4 cm' and 2.0 g/cm3
(4) 4 cm3 and 4.0 g/cm3
1
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³

2. Which specific cytoskeletal element is most susceptible to mitotic inhibitors?
Answer:
microtubules
Explanation:
Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.
What is Microtubules?The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.
They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.
Microtubules, which typically consist of 13 linear protofilaments arranged around a hollow core, are created when tubulin dimers polymerize to generate them. The head-to-tail arrays of tubulin dimers that make up the protofilaments are organized in parallel.
Therefore, Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.
