How are catastrophic events related to changes in geological timelines?
A. They aren't related to changes in the geological timeline because they don't change the
overall population dynamics.
B. They aren't related to changes in the geological timeline because the timeline is dictated
by temperature cycles.
C. They cause significant changes that disrupt the equilibrium of the earth and lead to
natural separation points.
D. They define geological periods because scientists use them as reference points for
tracking the history of the earth.
PLEASE ONLY ANSWER IF YOU KNOW-
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.

beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.
If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.
Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.
What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?
A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.
B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.
C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.
D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
Answer:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.
Explanation:
hope this helps you a little have a great day sir/mam
Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy. Thus option A is correct.
What is the function of catalase ?Catalase is a common enzyme present in all living organisms.
These are tetramer molecule consisting of four polypeptide chains, each of these chains are over 500 amino acids.
In mammal it is found in liver and contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide.
In mammalian cell, Catalase involve in decomposition of most toxic substance called hydrogen peroxide into less toxic products like water and oxygen.
It protect the cell from oxidative damage by reactive oxygen species.
The optimum pH and optimum temperature for the activity of this enzyme ranges from four and eleven depending on the species.
Thus option A is correct.

Energy Storage in Humans Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. What is the best conclusion based on this data? Blood is a primary location for energy storage. Fat molecules contain more energy-containing bonds than simple sugars. A gram of glycogen has twice as much energy as a gram of fat. The human body stores approximately 1,000 kcal of glucose.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)

what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).

How would the cycle be different if there were no water on earth?
Answer:
What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:
water.usgs.gov
water.usgs.gov
So what would happen if there were no condensation stage?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.
Without clouds, I foresee a few things happening:
From clouds come rain. With no clouds, there would be no rain.
Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.
Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.
And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Which statements describe incomplete dominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Incomplete dominance involves the interaction of two alleles. which ones are right?
Answer:
Traits are neither dominant nor recessive.
Offspring exhibit an intermediate form of alleles from the parents.
Incomplete dominance involves the interaction of two alleles.
Explanation:
In genetics, incomplete dominance (also known as partial dominance) is produced when the dominant allele doesn't mask the effects of the recessive allele, which is also expressed in the phenotype. In consequence, heterozygous organisms for a gene exhibiting incomplete dominance will be a mix (or blend) as a result of the expression of both characters. In humans, for example, Tay-Sachs disease is a genetic disorder characterized by a gene that exhibits incomplete dominance, where heterozygous individuals are still able to produce a key enzyme (hexosaminidase A) due to expression of the wild-type allele, while homo-zygous individuals for Tay Sachs recessive mutation usually die by the age of 4.

During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus if a portion of the original strand is tcga actca, then the new strand will be
Answer:
agcttgagt
Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".
Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.
