Is diffusion the only way materials can enter the cell? Explain.

Answers

Answer 1
Answer: Of course not! There's lots of ways materials can enter. It also depends on the cell; whether it has cell wall and cell membrane or only cell membrane.

Besides diffusion, there's also osmosis and active transport.

If the cell has only cell membrane, it means it's partially permeable, which means osmosis can happen.

Cell Membrane and cell wall (I think) :) I don't think nucleus is though because one of the cells has 'genetic strand' not a nucleus/'brain' :)

cyanobacteria have been engineered to produce isobutanol directly. what advantage does this have over other alternative biofuels? a. it is an inherently renewable fuel source. b. multiple processing steps can be avoided. c. they produce chemical energy through photosynthesis. d. they make a biofuel alternative to gasoline.

Answers

The advantage does this have over other alternative biofuels is multiple processing steps can be avoided.

Cyanodiesel is derived from one of the oldest living elements in nature, cyanobacteria. They have unlimited development potential and are a microbial element of diverse biotechnological applications.

What benefits can cyanobacteria bring?

Cyanobacteria have benefits for nature and for humans, such as:

  • Transform solar energy into chemistry through photosynthesis;
  • Present economic value in the pharmaceutical and agricultural sectors;
  • Fix atmospheric nitrogen, contributing to soil fertility.

We are able to learn all of the following from fossils EXCEPThow living things change over time
bone structure of an organism
the type of hair animals had
the type of teeth an animal had

Answers

you can't learn the type of hair creatures had in fossils as hair is very hard to fossilize because what makes things fossilize is after it gets old enough a layer of hard rock will eventually turn into a fossilized object. anything can fossilize as long as it is physically strong enough to withstand 1,000 years of age.

What are the three main parts of the geosphere?.

Answers

Planet earth is generally thought of a composed of the atmosphere, the hydrosphere, the lithosphere and the biosphere. The geosphere is often used to mean the same thing as lithosphere - rocks and stones. If this is how you are using the word, then the geosphere consists of the crust, the mantle and the core.

Final answer:

The three main parts of the geosphere are the crust, mantle, and core.

Explanation:

The three main parts of the geosphere are the crust, mantle, and core. The crust is the outer layer of the Earth and consists of oceanic basalt and continental granite. The mantle is the largest part of the Earth's interior, lying between the crust and the core. It is more or less solid but can deform and flow slowly. The core is the central part of the planet and consists of higher density material.

All of the following are renewable sources of energy except _______ power. A. nuclear B. solar C. geothermal D. wind

Answers

Answer: The correct answer for the fill in the blank is- A) Nuclear power.

Renewable sources of energy are those resources that can be replenished or renewed naturally. They do not run off that is they are inexhaustible.

Example of renewable sources- Solar energy, wind energy, geothermal energy, hydro-power.

On the other hand, non renewable source of energy are exhaustible and can not be replenished naturally.

Nuclear power ( resulted due to heat produced in the fission of atoms) is non- renewable source of energy. This is because the fuel that is used in most of the nuclear fission reactions is uranium, which is found in fixed amount on earth.      


nuclear is not a renewable source because uranium is used for nuclear power and uranium is limited.

In the typical cell cycle, DNA synthesis occurs in the _________ phase.

Answers


Deoxyribonucleic acid (DNA) synthesis refers to the creation of a new DNA molecule, which occurs in the cell cycle’s synthesis phase (S phase). Duplication of the centrosome, which organizes microtubules to help insure proper chromosomal segregation during cellular division, as well as DNA replication occur during this phase and are necessary for the stimulation of cellular division. {Synthesis phase}
