Answer:

Option (A).

Explanation:

Facilitated diffusion may be defined as the process of  movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.

Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.

Thus, the mismatched pair is option (A).

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end o
Ilia_Sergeevich [38]

Answer:

20 chromosomes

Explanation:

Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.

In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.

Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

How is the simulation different from the real world? Explain in 3 or more sentences.
Aleks [24]
Simulations generally involve a simple design. In contrast, the world is a very complex system. Many events, such as how we farm, can disrupt the world's delicate balance. Simulations do not take into account the varied interactions that affect events in the real world.

All living things contain carbon.which of the following statements is true about carbon atoms?
vfiekz [6]

I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.

Answer:

All the given choices

Explanation:

Carbon is a very interesting element which is the backbone of most organic compounds.

Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;

  • An atom of carbon has 4 valence electrons and can bond with 4 other carbon.
  • Carbon can form single, double and triple covalent bonds.
  • They can join together to form rings or chains.

How are fungal cells different from plant and animal cells?​
ycow [4]

Answer:

Fungus, A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, those being Plantae, Animalia, Protozoa, and Chromista.

Explanation:

Fungi and animals are very different from each other and classified as completely separate kingdoms. At the cellular level, both animals and fungi are composed of eukaryotic cells. Fungal cells differ from plant cells in that they do not have chloroplasts and cannot carry out photosynthesis to make their own food.
