Monarch butterflies are toxic to birds because monarch caterpillars eat milkweed.viceroy butterflies closely resemble the monarchs but are not toxic sinse the viceroy caterpillars do not eat milkweed. This similarity in appearance developed because viceroy butterflies that closely resemble monarchs are-
A) less likely to produce offsprings
B) less likely to be eaten by birds
C) more likely to make with monarchs
D) more likely to eat milkweed
Answer:
B Trust me
Explanation:
Less likely to be eaten by birds
The similarity in appearance between monarch butterflies and viceroy butterflies developed because viceroy butterflies that closely resemble monarchs are less likely to be eaten by birds. Thus, option B is correct.
What are viceroy butterflies?Limenitis archippus is scientific name of viceroy butterflies which is a North American butterfly. Since the viceroy is distasteful to predators, it is considered a Müllerian mimic.
The viceroy found in most of the contiguous United States as well as parts of Canada as well as Mexico. The caterpillar of viceroy butterflies feeds on trees in the willow family Salicaceae which includes willows, poplars, cottonwoods. The caterpillars isolate salicylic acid in their bodies, and therefore tastes bitter, and upsets predators' stomachs.
In natural phenomenon called Müllerian mimicry two or more well-defended species, which are foul-tasting and sharing common predators, mimic each other's honest warning signals.
Therefore, Monarch butterflies and viceroy butterflies are less likely to be eaten by birds so option B is correct.

Two students went for a walk in a small pond ecosystem where they observed several interactions. Read their observation below to find out what they saw. Small fish were found feeding on the green algae. Fish, frogs and snails were harder to find after a family of raccoons came to the pond. Fish and frogs were observed catching insects. As the amount of green algae increased, more insects and snails came to feed on it. A sample of the pond water contained bacteria.
Answer:
a food web
Explanation:
What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.
In this example, we observe there are seven organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.
The green algae are Producers (because it produces its own food, not dependant on others)
The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)
The other organisms are Consumers. (because they are dependant on others for their nutrition).

As per the experimental values, When the temperature decreases the time taken for the starch to be digested increases. This means that when the temperature is decreased, the metabolic rate also decreases resulting in the decrease in the rate of digestion. As we decrease the temperature everytime by the value of [tex]10^0[/tex]C, the rate of reaction decreases by the factor of 2.
_____________________________________A2)The slowest experiment was at Temperature [tex]20^o[/tex]C by the rate of 0.066 and The fastest experiment was at Temperature [tex]40^o[/tex]C by the rate of 0.32.
REASON:The reactants must contain sufficient kinetic energy to overcome a barrier called Activation Energy. Activation energy is the minimum amount of energy required to change the reactants into products. The Fastest reaction is at high temperature because when the temperature increases the molecules collide with one another more frequently, when the kinetic energy increases, more molecules make the effective collisions due to, so more molecules make up to the threshold energy. So increase in temperature increases the rate of the reaction.
_____________________________________A3)The optimum temperature for enzyme amylaze is 40 degree C because it has the fastest rate of reaction at that temperature. At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate., thus optimum temperature is 40 degrees, that is the reason why human body has temperature of 40.
_____________________________________A4)At high temperature the shape of the enzyme is altered so that it is no longer complementary to its specific substrate. Water boils at [tex]100^o[/tex] C and at 100 degree C the enzyme gets denatured.

A ball is dropped from height of 45 m. A second ball is thrown downwards from the same
with an initial vity both the balls reach the ground at the same time, culate the value of u
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s
41. Which of the following does not expend (use) energy?
a. diffusion
b. active transport
C. endocytosis
d.
a sodium-potassium pump
Answer: diffusion
Explanation: Diffusion expends no energy. Rather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low.
Among the options given, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.
What is Diffusion?Diffusion may be characterized as a type of movement of individual molecules of a substance from an area of higher concentration to an area of lower concentration through a semipermeable barrier. This biological movement cannot utilize any metabolic energy.
According to the context of this question, active transport is a type of transport of individual substance against a concentration gradient that actively require the use of metabolic energy. Apart from this, endocytosis and sodium-potassium pump also required energy for successful function within the body of living organisms.
Therefore, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.

how air enters from our mouth to toe?
When you breath in air through your mouth (or through your nose, but this question is asking about your mouth) it goes into your lungs. This oxygen then goes to various places round your body, one of these places being your blood stream. When the oxygen enters your blood stream, the blood could travel to your toe. This is how air would enter your mouth and get to your toe.
Answer:
When we breath air, it enters our trachea, which is the main passageway to our lungs. The lungs have something called bronchioles, which put that oxygen into tiny sacs and that air is delivered all across your body through arteries and veins! Vains reach to your toes, hands, and head, so they distribute oxygen everywhere.
In terms of the image below, the box on the top right is the example of the sacs of air in the bronchioles. The larger part of the image to the left is the overall respiratory system, and the arteries on the sacs of air are what deliver the air throughout the body.
