Need help with this!! I’m not good at writing these.
Answer:
The difference between ethical, and finally scientific questions, are based upon their root word. Such as an ethical question may involve race and heritage, while a legal question may involve anything that involves the law such as court questions and can be resolved by the judge not the jury. Finally scientific questions can involve a question thats mainly based around science such as items that you can test or measure.

Explanation:
What cell parts are common to all of these cells?
Use complete sentences.
Chlamydomonas
Spirogyra
Elodea
Squamous Epithelium
Answer: All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4). The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores. The filamentous masses come to the surface and become visible as slimy green mats. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts. This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. brainliest?
Explanation:
what is the function of cell
Answer:
Cell provide structure and support to the body of an organisms
Answer: They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. brainliest?

Oxygen molecules are sixteen times as massive as hydrogen molecules.
At the same temperature, which type of molecule would you expect to move faster?
Answer: hydrogen molecules.
Explanation: in same temperature molecules have same average kinetic energy.
You can estimate it solving E = 3/2 kT = 1/2 mv². Constant k is Boltzmann constant.
Lighter molecule has greater speed
A major cause of genetic variation within a species is the result of -
The table below shows the average distances of four planets from the sun.
Considering Kepler's Laws, which planet has the fastest average orbital speed?
A. Venus
B. Neptune
C. Saturn
D. Jupiter
Answer:
Venus
Explanation:
The closer a planet is to the Sun the faster it moves because the Sun can exert more gravitational force on it. Venus is the second closest planet to the Sun therefore the fastest out of the options.
Its Venus.
It is closer to the sun than the other planets on here.
describe sporangium fungi and club
Answer:
A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) 'spore' + ἀγγεῖον (angeion) 'vessel') is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. All plants, fungi, and many other lineages form sporangia at some point in their life cycle.
Explanation:
What happens if the mass of the elements is greater compared to smaller ?
Hello. More information is needed to answer your question accurately. However, I will try to help you in the best possible way
If you are referring to what happens if the mass of an atom is greater compared to an atomic number, we can say that there is nothing too much, since it is normal for the atoms to have a mass slightly greater than the atomic number. The mass of an atom can never be less than the number of protons added to the number of neutrons. An atom with greater mass has a greater number of electrons and neutrons in relation to an atom of less mass and it is likely that the atom of less mass will donate or share electron with the atom of greater mass so that both reach the electric balance.
