Answer:

1. Chloroplast

2. Photosynthesis

3. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

4. Sunlight

5. Glucose

6. Oxygen

7. Carbon Dioxide

8. Water

9. Energy

10. Mitochondrion

11. Cellular Respiration

12. C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

Answer:

1. Chloroplast

2.photosynthesis

3. 6 CO₂ (carbon dioxide) +12 H₂O (water) + light -->C6H12O6 (glucose/sugar) +6 O₂ (carbon dioxide) + 6 H₂O (water)

4. Light

5 and 6) Glucose (C₆H₁₂O₆) and O₂

7 and 8) CO₂ and Water (H₂O)

9) energy (ATP)

10) Mitochondria

11) Cellular respiration

12) I think you need the equation as well:

Explanation: C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) --> 6CO₂ (Carbon Dioxide) + 6 H₂O (water) + ATP (energy)

1. Chloroplasts have thylokoids or stacked membranes like it has.

2. Photosynthesis is the process of converting light into usable energy.

3. That is the equation of photosynthesis. Their are different ways of writing this for example: 6 CO₂ + 6H₂O + light -->C₆H₁₂O₆ + 6 O₂ which is balancing the water. Check to see what your teacher used in the book/notes.

4. Light is required for photosynthesis and the sun is providing it.

5 and 6) The mitochondria uses both of these in its processes that were first made in photosynthesis.

7 and 8) Both are created by mitochondria and are used in chloroplasts.

9) Energy is produced in the mitochondria with help from the Chloroplast.

10) It is usually depicted with those lines in it.

11) That is the process's name.

12) This is the equation of cellular respiration.

Industrialization, commercialization, rural-urban migration, lifestyle changes, career opportunities, social advantages, etc. are the primary reasons of urbanization. The process of urbanization is when people move from rural to urban areas for a variety of reasons.

What results did urbanization produce?

Urban areas can expand due to a rise in the population or because people move there. Urbanization frequently causes habitat loss, deforestation, and freshwater extraction from the environment, which can reduce biodiversity and change species ranges and interactions.

which molecules are not able to permeate the cell membrane

Answers

Answer:

Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

The answer would be B!!

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.

Answers

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

define magnification and cisternae?​

Answers

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

The heartbeat rate of an athlete during resting is lower than a non-athlete.
Explain why. [ 2 marks ]

Answers

Answer:  The heart muscle of conditioned athletes enlarges and strengthens.

Increased cardiovascular fitness causes real physical changes in the structure of the heart. The muscles in the heart wall thicken, and the heart pumps more blood with each beat. That increased efficiency means an athlete's resting heart rate falls to a level that could indicate trouble in a nonathlete. Many athletes don't realize that high levels of conditioning also cause heart symptoms that doctors might mistake for serious problems.

Occasionally a new resistant strain of pathogen appears. The new strain may spread rapidly. Explain why

Answers

Answer:

Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.

Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

Answers

Answer:

Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.
