Which of the following is a possible consequence of solid pollutants in a lake or river?
O Build-up of garbage in freshwater
O Quick drop in dissolved oxygen
O Decrease in algae colonies
O Sudden hypoxic waters



HELP PLZ

Answers

Answer:

I believe it would be B.) Quick drop in dissolved oxygen

Quick drop in dissolved oxygen is a possible consequence of solid pollutants in a lake or river.

What is Biological Oxygen Demand?

Biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions.

Solid pollutants in freshwater bodies like river and lake generally corresponds to organic wastes such as leaves, flowers and clothes which lead to increase in number of microorganisms in these water  that further results in increase of BOD.

Drastic increase in microorganisms lead to drop in amount of dissolved oxygen in water, thus the possible consequence of solid pollutants in a lake or river is quick drop in dissolved oxygen.

Answer these questions about making a yogurt.

1) why is the milk pasteurized at the start of the process?

2) Why is the mixture of milk and bacteria incubated at 45 °C?

3) what causes the milk to thicken?

4) why does fermentation eventually stop?

5) Explain how making yogurt is a way of preserving the nutrients from milk.

Answers

It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.

The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.

The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.

Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.

All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows bigger and makes copies of the parts inside it. Then, the cell and its parts separate into two new cells. Each new cell contains the same types of cell parts as the original cell. Later, each of these cells may divide again to form more cells. When a multicellular organism's cells divide, the organism can grow. Each resulting cell is part of that organism. When a unicellular organism divides, each resulting cell is a separate unicellular organism. The micrographs below show cells from two different organisms: Giardia, a unicellular protist, and banana, a multicellular plant. Giardia cells in a banana Which of the following statements are true?

a. A rose bush cell can divide to form two rose bushes
b. If the bacterium divides, it will become a multicellular organism
c. When a rose bush cell divides, it copies its parts then divides into two cells
d. The bacterium was formed when another bacterium divided

Answers

Answer:

c. When a rose bush cell divides, it copies its parts then divides into two cells and

d. The bacterium was formed when another bacterium divided

Explanation:

C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).

D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of  many cells.

Which group was not present in Linnaeus' system but is present in modern classification systems? A) Species B) Kingdom C) Domain D) Phylum HELP ME

Answers

Answer:

D) Phylum

Explanation:

The group that was not present in the Linnaeus' system but is present in modern classification systems is Domain. The correct option is C.

What is Linnaeus classification system?

The Linnaean classification system is based on a hierarchy of groupings known as taxa. Taxa vary from kingdoms to species.

The kingdom is the most extensive and inclusive grouping. It is made up of organisms that have only a few basic resemblances.

The Linnaean system is significant because it paved the way for the use of binomial nomenclature to distinguish between species.

Scientists could communicate instead of using misleading common names once the system was implemented.

Domain is a group that was not present in Linnaeus' system but is present in modern classification systems.

Thus, the correct option is C.

To test a new drug that has the potential of curing people of the common
cold a company asked human volunteers who were coughing and sneezing
to participate in a clinical study. The objective of the experiment was to test
whether the new drug could cure the volunteers in the experimental group of
the common cold. But instead of two groups, these volunteers were randomly
divided into three groups and treated as follows:
Group
Experimental
Group
Yes
Control
Group 1
NO
Control
Group 2
No
New ONS
Orange
Bedre
Yes
No
Yes
Yes
Which of the following is the best explanation of why a second control group
was included in this experiment?
O A To prove that the common cold cannot be cured
B. To provide the volunteers in the study with something to drink
O C. To help researchers conclude that results are related to the new
drug and not to the orange juice
O D. To confuse anyone who is trying to steal their new drug and sell it
as their own invention

Answers

Answer: C

Explanation: A good experiment does everything it can to eliminate confounding, or the influence of external sources on the data being measured. Orange juice could be a factor that plays a role in curing the symptoms, so provide a group with and without orange juice gives you the ability to show that the influence of orange juices didn’t have an effect on the cold, or did, but it gives you a baseline to show the effects of the medicine with and without orange juices.

what is Krebs cycle?
Is Krebs cycle also known as cellular respiration?

Answers

Explanation:

The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.

No Krebs cycle is not known as cellular respiration

why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?

A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.​

Answers

Answer:

i think the answer should be b.

the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!

btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!
