B. RED AND WHITE

C. BLACK AND WHITE

D. BLUE AND WHITE

Answer:

They can become any type of cell in the body.

Explanation:

They can transport molecules, metabolize nutrients, and reproduce within this one cell. ... Cell differentiation is the process by which cells become specialized in order to perform different functions. Specialized Cells in the Human Body. Multicellular organisms begin as just one single cell—a fertilized egg.

Answer:

Very large molecules such as proteins are too big to move through the cell membrane which is said to be impermeable to them. The type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. Glucose molecules travel through the proteins.

Answer:

Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

Hello!!

What tissues make up a leaf?

Leaves include two different types of photosynthetic parenchyma cells (palisade and spongy). Like all plant organs, they also contain vascular tissue (not shown). Monocots tend to have parallel veins of vascular tissue in leaves, while dicots tend to have branched or net-like veins of vascular tissue in the leaves.

can you please give me brainliest

Answer:

The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.

The genome, which is the second layer, regulates gene access, allowing each cell type to activate its own unique genes while shutting off the majority of the others.

The complete set of DNA instructions present in a cell is known as the genome. The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.

Everything a person needs to grow and operate is encoded in their genome. The DNA sequence in a cell's genome contains the instructions needed to create tens of thousands of different protein and RNA molecules.

Thus,  in multicellular organisms, distinct cell types develop because diverse sets of genes are expressed, even though a cell normally expresses just a portion of its genes.

Answer: a+c

ExplanationExplanation:

Answer:

The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.

For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.

Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.

Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.

However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.

Answer:

The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS)

I hope it helps btw please follow me & please mark me as the brainless

The nervous system as a whole is divided into two subdivisions: 

Central nervous system (CNS)

Peripheral nervous system (PNS).

Answer:

Yes. Unicellular organisms died because of a change in temperature, which is an environmental change. If the environment on Earth changes too much, it will affect living things. If the changes are too drastic, life may not be able to survive.

What two conditions are necessary for osmosis to take place

The conditions required for osmosis are:

Two solutions having different solute concentration.

A semi-permeable membrane. When two solutions having different concentration of solutes is separated by a semi-permeable membrane, the solvent moves from the region of high concentration of solvent

Answer:

b. The heart

Explanation:is correct

Answer:

b to a

Explanation:

since cells in membranes move from high to low concentration (diffusion). b has more molecules, so it will go into a.

Answer:

The large intestine

Explanation:

The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.

As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

Hopefully that was helpful! :)

The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.

The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).

The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.

The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.
