What does lemon juice, snake venom and cyanide have in common?
Answer:
enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.

Geese fly in a v-like formation when migrating. Which statement is evidence that supports advantages of this group behavior? (4 points)
A) Birds can work together to find food and shelter.
B) Birds conserve energy and reduce wind resistance.
C) Birds need to move faster to avoid being seen by predators.
D) Birds can compete for mates when they fly together.
Answer:
B
Have a nice day :D
Birds conserve energy and reduce wind resistance when they fly in V-like formation.
Why Geese fly in a V-like formation?Flying in a v-like formation allows geese to conserve energy and reduce wind resistance as they migrate. The lead goose breaks the wind for the rest of the group, which allows the other geese to fly more efficiently and use less energy. This group behavior helps the geese to cover long distances during migration, as they are able to fly for longer periods of time without tiring.
The other options do not provide evidence of advantages of this group behavior. Option A) may be true, but it is not specific to flying in a v-like formation. Option C) is not necessarily related to group behavior, as geese may need to move faster for other reasons. Option D) is not relevant to the topic of migration.

The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

PLS HELP FAST!!!! You have a natural-gas (methane, CH4) stove. When you ignite a natural-gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. Write a balanced equation for this reaction, and be sure to show your work. (6 points)
Answer:
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Explanation:
The balanced equation for the reaction of methane with oxygen is CH₄ + 2O₂→CO₂ + 2H₂O.
What is methane?Methane is a gas and a chemical compound with formula CH₄. It is a colorless and odorless gas and very flammable. It is made up of carbon and hydrogen. Methane comes under greenhouse gas.
As it is highly reactive, it reacts with the gases present in the environment. Here, methane is reacting with oxygen. When one molecule of methane reacts with two molecules of oxygen, it produces carbon dioxide and two molecules of water.
The reaction happens in the presence of heat and high temperature. The balanced reaction is written when the same number of moles are present on both sides of the reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O.
Thus, the balanced equation for the reaction CH₄ + 2O₂→CO₂ + 2H₂O CH₄ + 2O₂ → CO₂ + 2H₂O.

Bats are common in Texas especially in rocky regions bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting this adaptive on is becoming more frequent in the population.What mechanism of evolution is this
Answer:
Natural selection
Explanation:
Natural selection is the mechanism of evolution in which organisms evolve in order to adapt the changes in the habitat for their survival. Living organisms are naturally variable and adjust themselves according to their surroundings.
In the given example, bats in Texas evolve themselves with longer hang claws to adapt the rocky nature of the surrounding. These longer hang claws provide them the ability to cling to the rock, which is an adaptive feature of bats that is influenced by the environment.
Hence, the correct option is "Natural selection".

Why are there fewer tuskless elephants born after the war (ages 10-20 years old)?
Elephant tusks are either present or absent due to genetics, specifically the existence of key genes that regulate tusk growth. Environmental elements, however, can also affect the proportion of tuskless elephants in a population.
Elephants are frequently hunted down during conflicts or wars for their ivory tusks, which are highly sought-after on the illicit market. Over time, the population of elephants with tusks may decline as a result of this selective hunting of those with them.
The age range of 10 to 20 years old is essential because it coincides with the period of time when elephants usually begin to grow their tusks. Around the age of 6 to 8 years, young elephants may start developing their tusks, and by the time they are 10 to 20 years old, their tusks should typically be more noticeable and developed.
It is possible that many young elephants with developing tusks will be killed if a conflict or a period of rampant poaching takes place during this crucial time, which will reduce the number of tusked elephants in the population. After such a conflict or a period of heavy poaching, there can be a larger percentage of tuskless elephants between the ages of 10 and 20.
This theory makes the assumption that there was greater poaching or selective hunting occurring during the conflict, which would have a disproportionately negative effect on elephants with tusks. In order to provide a more comprehensive knowledge of the issue, additional examination of local conditions and data would be required. The individual situations and variables affecting elephant populations can differ.

Answer:
Carbon sinks can be natural or man-made. They absorb more carbon than they release, whereas carbon source is anything that releases more carbon than they absorb. ... Together Earth's land and Ocean sinks absorb half of the carbon dioxide emissions.

Humans can be considered carbon sinks - yes, for a lifetime.
living organisms are better long-term sinks than humans - plants or trees.
Carbon sinkanything that absorbs more carbon from the atmosphere than it releasesit is the opposite of a carbon source as a carbon source is anything that releases more carbon than it absorbsHumans release carbon mainly by respiration, however, absorbs very less amount as foodPlants grab carbon dioxide from the atmosphere to use in photosynthesis and only some of this carbon is released to the soil when plants die and decomposeLearn more:

With statement best describes the anther in a flowering plant? A. It is the colored part of the flower that attracts pollinaters. B. It is the part of the stem that supports the weight of the plant. C. It is the part of the stamen that contains the pollen. C. It is the part of the flower that contains the eggs.
Answer: C. It is the part of the stamen that contains the pollen
Explanation:
Anthers are the pollen containing units in a flower that can be found in the stamens of such flowers. It should be noted that typically, anthers consist of two parts which are referred to as the thecae and each one of the theca is made up of two microsporangia.
Therefore, from the explanation above, we can infer that the another is the part of the stamen that contains the pollen.
