Contact [7]3 years ago

Answer and Explanation:

Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.

Their wings skeleton have the shape of finger/hands like a human.

Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.

Answer:

Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

Prompt 3: Why do you think it is so
kicyunya [14]

Answer:

there will have to be something to produce all the food so that other animals can eat

also when u eat u decompose so they are inportant as they decompose

as when they decompose they lay fertilisers for the soil in the floor so that other plants can grow amd flourish so the cycle can continue

Explain how osmosis will affect animal cells when the cells are placed into and environment with a low water potential compared
matrenka [14]

Answer:

Explanation:

The cytoplasm in animal cells is surrounded by a membrane, which delimits the cell and its surroundings. As opposite from the plant cells, animal cells do not have a cell wall.

<em>Osmosis</em><em> is the process in which a solvent diffuses across a semipermeable membrane</em> (like the cell membrane) <em>from the zone with the lower concentration of solutes to the zone with the higher concentration. </em>That means that water, in this case, will diffuse spontaneously across the cell membrane from the place with more water molecules (usually, the exterior of the cell) to the place which has less water molecules, or is more concentrated (in this case, the cytoplasm). This diffusion will continue until an equilibrium is reached.

If we place an animal cell, which does not have a cell wall, into an environment with a low water potential, <u>the water will flow from the exterior to the interior</u>. If the water potential is very low compared to the one of the cytoplasm, the cell can receive too much water and explode. This process is called cytolysis.

g If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time
Elenna [48]

Answer:

a. 8.1 milligrams

b. 40.07 hours

c. 8.859 milligrams

Explanation:

If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by

A_{t}=10e^{-0.0173t}

Where A(t) = amount of Valium remaining in the blood after t hours

t = time or duration after the drug is taken

a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours

A_{12}=10e^{-0.0173\times12}

A_{12}=10e^{-0.2076}

                = 10×0.81253

                = 8.1 milligrams

b. In this part we have to calculate the time when A(t) = 5 milligrams

5=10e^{-0.0173\timest}

\frac{5}{10}=e^{-0.0173t}

0.5 = e^{-0.0173t}

Now we take natural log on both the sides of the equation.

ln(0.5) = ln(e^{-0.0173t})

-0.69314 = -0.0173t

t = \frac{0.69314}{0.0173}

t = 40.0658

 ≈ 40.07 hours

c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.

A_{7}=10e^{-0.0173\times7}

A_{7}=10e^{-0.1211}

              = 10×0.8859

              = 8.859 milligrams

_____ helps prevent mutations from occurring over and over again. Binary fission; Multiple fission; Mitosis; Meiosis
Kipish [7]
<span>Meiosis helps prevent mutations from occuring over and over again. In Meiosis process, the number of chromosomes during reproduction was caused in half. During this process, the chromosomes that could potentiall caused mutation could be tossed out and therefore reduce its chance from happening</span>
