Answer:

<em>The correct options are B and C</em>

Explanation:

Option A is false because bacteria fix nitrogen by converting it into ammonia. The ammonia is used by the plants for different functions like development etc.

Option B is correct because plants can take up both ammonium ions and nitrate ions from the soil. They use these ions to make amino acids which are required by the plant for different activities.

Option C is correct because nitrifying bacteria are the bacteria which convert ammonia into nitrites and then nitrates in a process which is termed as nitrification.

Option D is false because herbivores eat plants to make amino acids and proteins.

If your lac operon looked like the image below, which of the following can you infer?
Marysya12 [62]

Answer:

You have not consumed lactose from dairy recently

Explanation:

According to the diagram, there is a represssor element in the regulatory region of the operon. This repressor is blocking the RNA polymerase, that is bound to its promoter region upstream of the genes, from transcription. The repressor is mostly the lac repressor that switches of the operon in the absence of lactose.

Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change?
ankoles [38]

Answer:

Heyya!

Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life.  When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.

1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.

it contains the genetic/hereditary materials that the cell is made up of.

The Nucleus plays a great role in the control of growth and development of the cell.

The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.

2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.

3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.

The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.

4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.

5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.

6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.

The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.

7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.

The cell membrane as well controls the movement of cellular materials in and out of the cell.

8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,

9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.

The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.

Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.

10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.

The cell wall houses the organelles of the plant cell.

The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.
