Why do fewer kinds of organism live in desert than in forest biome

1 answer:

Hi there!

Great question!

Fewer kinds of organisms live in deserts than forests because they have special adaptions to their own home... and there are a few, loooong examples below for you to read.

ENJOY!

Camels have a water storage in their humps on their back, so they can go a long time without drinking any water. They have tan fur color to blend in with the sand for predators. They have a short-haired coat on most of their body because of the hot sun, but because deserts can get very cold at night (almost dropping temps below 0), they have thicker fur on their humps and neck. If they were moved to the forest biome, they would take a long time to adapt to their new home.

Next example can be a wolf. A wolf can live in the forest because it has adapted over time to make a wolf, well, a wolf. It has thick fur for keeping it warm at night and in wintertime. A wolf has such a particular diet, that if it lived in a desert, it wouldn't find much food. In the desert, there are snakes and scorpions and bugs, whereas the forest has the deer and caribou to eat.

See, so its pretty simple. Basically, animals live where they live for a reason. If you just moved them to somewhere else in the world, and this could be anywhere, they would take a loooong time to adapt to their new homes.

* A great example of animal adaptation over time is the spirit bear. A spirit bear is a black bear, with white fur, and they aren't albinos. Its a hair color that is very rare, and according to scientific studies, the ratio to spirit bears and black bears in the forest is 1:10. They have developed white fur overtime because the black bears are much darker than the spirit bears, and fish underwater, their source of food, can see them right above the water before the bear dives for a meal. The Spirit bear, however, has a better time catching the fish underwater because it has white fur, not allowing the fish to see her above. Then she dives in for the catch and is successful! *

Design a modified priority encoder that receives an 8-bit input, A7:0and produces a 3-bit output, Y2:0. Y indicates the most sig

cupoosta [38]

Answer:

Explanation:

The first image that I attached to this solution is the diagram of a truth table for an 8 to 3 bit encoder.

The second image gives a sketch of the schematic.

The Boolean expression for the priority encoder including its zero inputs is defined in the third image attached.

Below is a snippet of the code for an 8 to 3 bit Priority encoder:

library IEEE;

use IEEE.STD_LOGIC_1164.all;

entity encoder8_3 is

port(

din : in STD_LOGIC_VECTOR(7 downto 0);

dout : out STD_LOGIC_VECTOR(2 downto 0)

);

end encoder8_3;

architecture encoder8_3_arc of encoder8_3 is

begin

dout <= "000" when (din="10000000") else

"001" when (din="01000000") else

"010" when (din="00100000") else

"011" when (din="00010000") else

"100" when (din="00001000") else

"101" when (din="00000100") else

"110" when (din="00000010") else

"111";

end encoder8_3_arc;

A bullet with a mass ????b=13.5mb=13.5 g is fired into a block of wood at velocity ????b=253vb=253 m/s. The block is attached to

Lorico [155]

Answer:

450 grams

Explanation:

Given:

mass of the bullet, m = 13.5 g = 0.0135 kg

velocity of the bullet, v = 253 m/s

spring constant of the spring, k = 205 N/m

Compression of the spring, x = 35.0 cm = 0.35 m

Now, the kinetic energy of the moving system (bullet + board) will tend to move the spring

thus,

let velocity of the system, V

now, applying the concept of conservation of momentum, we have

mv = (M + m)V

where,

M is the mass of the block

thus,

V = mv/(M + m)

now,

the kinetic energy of the system = (1/2)(M + m)V²

the kinetic energy of the system = (1/2)(M + m)(mv/(m + M))²

Energy gained by the spring = (1/2)kx²

now,

equating both the energies, we get

(1/2)(M + m)(mv/(m + M))² = (1/2)kx²

(mv)²/(m + M) = kx²

on substituting the values, we get

(0.0135 × 253)²/(0.0135 + M) = 205 × (0.35)²

11.66/(0.0135 + M) = 25.1125

M = 0.450 kg = 450 grams
