In 3 minutes, a damselfly's wings beat 2700 times and a butterfly's beat 2100 times. The damselfly's wings beat approximately 600 times more in one minute than the butterfly's.

In order to find the difference in the number of wing beats between the damselfly and the butterfly in one minute, we need to subtract the number of wing beats of the butterfly from that of the damselfly.

The damselfly beats its wings 2700 times in 3 minutes, which means it beats its wings approximately 900 times per minute (2700 divided by 3). On the other hand, the butterfly beats its wings 2100 times in 3 minutes, which means it beats its wings approximately 700 times per minute (2100 divided by 3).

By subtracting the butterfly's wing beats per minute from the damselfly's wing beats per minute, we get the difference: 900 minus 700 equals 200. Therefore, the damselfly's wings beat approximately 600 more times in one minute than the butterfly's.

Answer:

Explanation:

Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. ... Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

When a reaction releases more energy it is known as ; ( B ) exothermic reaction

Exothermic reaction is a chemical reaction whereby energy required to carry out a reaction is less than the energy expended into the environment during the reaction. Exothermic reactions give out energy in the form of heat into the environment .  While

Endothermic reactions absorb energy in the form of heat from the environment during a chemical reaction. ( i.e. energy required to carry out the reaction is greater than the energy expended by the reaction ).

Hence we can conclude that when a reaction releases more energy than it uses it is an exothermic reaction.

If an atomic mass of element is 3 units and an atom of element b has a mass of 7 units, what would be the ratio of element a to element b in a compound that has a mass of 26 units is 3A for every 1B

Let X's atomic mass be w and Y's atomic mass be 2w (as they are in the ratio 1:2).

Given: Compound X weighs 50%

Compound Y thus equals (100-50)% or 50%.

Because X:atomic Y's mass ratio is 1:2, we may write:

X = \s1 \s50 \s​ \s =50

Y = \s2 \s50 \s​ \s =25

Additionally, simplifying the 50:25 ratios results in 2:1.

Therefore, the empirical formula is X 2 Y.

Answer:

When the soot vanished, the light-flecked moths started to repopulate. Their numbers increased as the dark peppered moths began to decline.

Explanation:

Once the soot disappeared, the light-colored moths reappeared and their numbers increased. The dark-colored moth population is declining.

Industrial melanism is a type of natural selection. In natural selection, nature selects the fittest individual that can live and reproduce.

Light-coloured moths were originally camouflaged with the light colored bark. Hence, predators couldn't differentiate between the bark and the light moth. Predators feed upon dark moths, as they are clearly visible.

After industrialization, the soot covered the bark, and as a result, the bark turned black. White moths were easily differentiated from the dark bark and fed by predators. The population of light moths declined, and the population of dark moths increased as they gained an advantage due to industrialization.

After the soot vanished, the bark turned light again, giving the light-colored moth an advantage. They could hide from the predator. Dark-colored moth populations again declined as they fed upon predators.

Hence, after the soot disappears, the dark moth population declines and the light moth population increases.

Answer:

Blood vessel dilation in the dermis is allowing increased blood flow from the deeper tissues to the skin.

Explanation:

Our skin feels hot when you have a fever because of the process known as vasodilation in which the widening of blood vessels occurs that increases the blood flow. Due to this process, blood flow to the skin increases that causes the temperature to rise and as as result sweating as well as dehydration occurs in order to remove heat from the body. So we can say that vasodilation is responsible for the increase in temperature of our body.

The primary structure of proteins is disrupted through the hydrolysis of peptide bonds. The peptide bonds are formed between the amino acid residues during the process of protein synthesis. The level of protein structure that is disrupted by the hydrolysis of peptide bonds is the primary structure of proteins. The primary structure of proteins is the sequence of amino acids held together by peptide bonds, also known as polypeptide chains.

Hydrolysis is the process of breaking the peptide bond in proteins. During hydrolysis, the peptide bond is broken by the addition of water. A molecule of water is split into hydroxide ion (OH-) and a proton (H+) in the process. The OH- attacks the peptide bond, causing it to break, and resulting in two amino acids. The hydrolysis of peptide bonds is an important process in the digestion of proteins.

The primary structure is disrupted when hydrolysis occurs. Consequently, it impacts the higher levels of protein structure such as the secondary, tertiary and quaternary structures which are stabilized by interactions such as hydrogen bonds, disulfide bonds, and van der Waals interactions.

1) The rate of a reaction depends on the temperature, the activation energy, and the concentrations of the reactants.

2) Enzyme-catalyzed reactions can exhibit zero order kinetics when the enzyme is saturated with the substrate, meaning that the reaction rate is independent of the substrate concentration.

There are a number of variables that can affect a reaction's pace, but temperature and reactant concentrations have the biggest impact. The rate of a reaction is often higher when both the activation energy and reactant concentrations are high.

On the other hand, the pace of the reaction slows down when the activation energy is relatively high or the reactant concentrations are low. When an enzyme becomes saturated with a substrate in an enzyme-catalyzed reaction, the reaction rate can display zero order kinetics and be limited regardless of the substrate concentration.

This is because the enzyme's full catalytic capability has been reached and no more  rate of reaction can be achieved by adding more substrate.

Explanation:

At the end of the manipulation, there are 1 × 10^3 cells in tube 3

The initial tube contains a cell concentration of 1 × 10^6 cells/ml. Therefore, the number of cells in the initial tube is 1 × 10^6 cells/ml.

To calculate the number of cells left in the initial tube, we can determine the number of cells that were removed when 100 µl was taken out. This can be calculated as follows:

Number of cells removed = 1 × 10^6 cells/ml × 100 µl = 1 × 10^6 cells/ml × 1 × 10^-4 L/µl × 100 µl = 100,000 cells.

Regarding the number of cells in tube 3 after the manipulation, we know that the volume of cells in tube 2 is 100 µl, corresponding to 1 × 10^5 cells. When tube 2 is mixed with 900 µl of medium in tube 3, the total volume in tube 3 becomes 1 ml (100 µl + 900 µl).

Hence, the number of cells in tube 3 is calculated as follows:

Number of cells in tube 3 = 1 × 10^5 cells/100 µl × 1 ml/1,000 µl = 1 × 10^3 cells.

Therefore, at the end of the manipulation, there are 1 × 10^3 cells in tube 3.

The correct option is first, as the jackrabbit's circulatory system increases blood flow to the ears during hot days and blood flow to the ears decreases during cool or cold nights.

Homeostasis is vital to preserving an ideal environment for cell structures to work effectively. The direction of a cell or an animal's inner environment in reaction to changes within the outside environment is called homeostasis.  

In this case, the jackrabbit's circulatory framework is reacting to fluctuating temperatures.

On hot days, the body is at a chance of warming up over ideal temperature which might obstruct body capacities. In this manner, the bloodstream to the ears is expanded to encourage heat loss.

In cold temperatures, the bloodstream to the ears is diminished to moderate warm for crucial body organs. The bloodstream is coordinated to the center of the body to secure the heart, lungs, liver, and brain.
