Explain the differences between osmosis, diffusion, active transport and bulk transport

Biology
1 answer:
Feliz [49]3 years ago
3 0
Osmosis is the process by which molecules of a solvent pass through a semi-permeable membrane from a less concentration to a higher concentration.

Diffusion is the passive movement of molecules from a higher concentration regions to a region of lower concentration.

Active transport is the movement of molecules against a concentration gradient.

Bulk transport is the movement of macromolecules into or out of the cell

List a second food chain
FromTheMoon [43]

Answer:

see in the picture below

Explanation:

A food chain is a flow of energy from a green plant (producer) to an animal (consumer) and to another animal (another consumer) and so on. In this lesson we are going to talk all about food chains and food webs in the environment.

If a cell is in a hypertonic solution, which statement is true about water movement and the cell?
Solnce55 [7]
More water leaves the cell than enters the cell. Since it is a hypertonic solution, the surrounding medium has lesser concentration of water than the cell

Using the following biomass data, determine which groups is most likely to represent the producers in an area.
zlopas [31]

Number of producer depends on ecosystem we are talking about. I am taking this question as terrestrial ecosystem so for the terrestrial ecosystem the answer will be group D.

In terrestrial ecosystem number of producer is higher than the second trophic level that is primary consumer. To study this we use pyramid of number. In most cases the pyramid of number is upright with members of successive higher trophic level being fewer than the previous one. The maximum number  of individuals occurs at the producer level.

In peas, the allele for yellow seeds (Y) is dominant to the allele for green seeds (y). What would be the genotype and phenotype
grin007 [14]
<h2>The correct answer is explained below:</h2>

Explanation:

  • The allele for yellow seeds is Y.
  • The allele for green seeds is y.
  • The yellow colour phenotype is dominant over the green color phenotype.
  • The genotype of the parent who is heterozygous is : Yy.
  • The gametes produced by the parent who is heterozygous are: Y and y.
  • The genotype of the parent who is homozygous recessive is: yy.
  • The gamete produced by the parent who is homozygous recessive is: y.
  • Crossing the above parents we get the following offspring,

                                           Y                    y

                               y         Yy                  yy

               Phenotype      Yellow          Green

  • The genotype and the phenotype of the possible offspring is represent in the Punnett square above.
  • The ratio of the genotype is Yy : yy = 1 : 1.
  • The ratio of the phenotype is Yellow : Green = 1 : 1.

Which of the following best describes how the photosynthesis in grass cells is related to the cellular respiration in a cow's ce
Firlakuza [10]

Answer:

The correct answer would be option B .

Photosynthesis and cellular respiration are complementary in nature as they produce substrates for each other.

Photosynthesis is the process by which plants or photoautotrophs like green plants, grass et cetera make their food or glucose from simple compounds like carbon dioxide and water in presence of sunlight and chlorophyll.

The oxygen is released as the byproduct.

6 CO₂ + 6 H₂O + solar energy → C₆H₁₂O₆ + 6 O₂

In contrast, the animals or consumers such as cow use these products (glucose and oxygen) to produce energy in the form of ATP through the process of cellular respiration.  

Carbon dioxide and water are released as the waste product of the process.

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy (ATP)
