What happened to the cheetahs?

Answers

Answer:

Explanation:

The chief threats to the cheetah's existence are loss of habitat, poaching and hunting (their hide and trophies can command top dollar), and getting shot by livestock farmers. Decline of gazelles, wildebeests, impalas and other preferred prey species (also due to hunting and habitat loss) is a factor, too.

There are various subspecies of cheetah. So the cheetah's disappearance would have differing effects in each case. In general terms, however, the cheetah is a predator and hunter at the top of the food chain, so its disappearance would impact its prey and so on down the line.

The Great Plains are made up of the Canadian provinces of Alberta, Manitoba, and Saskatchewan as well as the American states of North Dakota, South Dakota, Montana, Nebraska, Kansas, Oklahoma, Texas, Wyoming, Colorado, and New Mexico.

Sheep are currently the animal raised on prairie terrain. Millions of prairie dogs and thousands of bighorn sheep were nourished by vast, uninterrupted horizons of continuous grasslands.

Additionally plentiful were the birds, which included more than 3 billion passenger pigeons, various grouse species, and greater prairie chickens.

Thus, the correct option is A.

Which statement best describes the cell membrane of a living cell?
A) It is composed of proteins and carbohydrates
B) It has the same permeability to all substances found inside or outside the cell.
C) It is a double protein layer that doesn't allow things to pass through it.
D) It selectively regulates passage of materials into and out of the cell..

Answers


Answer: The cell membrane of a living plant cell ( selectively regulates the passage of substances into and out of the cell (option D). Explanation: The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.

D) It selectively regulates passage of materials into and out of the cell.

Calculate the rate of photosynthesis(mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 5 min and, when measuring cellular respiration it took 20 minutes for the water level to move down 1mm.
63mm/hr
57mm/hr
67mm/hr
61mm/hr
52mm/hr

Answers

Answer:

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).
