The practice of removing natural vegetation and replacing it with concrete and structures is known as urbanization. This is the correct answer to fill in the blank.

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.

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.

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.

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.

Answer:

Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds.  The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.

Answer:

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Answer: try B

Explanation:

As a cell's size increases, the amount of DNA stays the same. The information used to build the molecules needed for cell growth is in the DNA. If a cell grows too large, an "information crisis" would occur.

Answer:

The answers is B

Explanation:

I just took a test that had this question on it.

B. contact with an infected person

Transmission occurs when an infected person interacts or exchanges bodily fluids with another person.  This can happen before the infected individual even realizes they are sick.

After a weekend field trip to the aquarium with their classmates, five pupils catch a cold. Because they may have come into contact with an infectious person, students became ill. Students became sick as a result of B. contact with an infected person

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.

Answer:not applicable in all situations.

Explanation:I checked it

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.

We can see that the separated sister chromatids are being pulled by the cell's centrosomes (microtubules) from both poles of the cell.

Answer:

Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.

Answer:

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes . Meiosis also produces genetic variation by way of the process of recombination .

Explanation: Meiosis is important for three main reasons : it allows sexual reproduction of diploid organisms , it enables genetic diversity , and it aids the repair of genetic defects .

Answer:

Describe the three ways meiosis produces genetic variability. We have seen that meiosis creates variation three ways: crossing over, mutations caused during crossing over, and independent assortment.

Answer:

1. Chloroplast

2. Photosynthesis

3. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

4. Sunlight

5. Glucose

6. Oxygen

7. Carbon Dioxide

8. Water

9. Energy

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)

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.

Answer:

Isotonic: there would be no net flow of water, the cell will stay stable

Hypotonic: the cell will fill up with water and burst

Hypertonic: The cell will shrink because it loses water

Explanation:

Answer:

Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.

Answer:

Water is needed for your digestive track as it digests foods. As water is also needed for each cell to properly function in your body.
