Answer:
Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.

The graph below shows the relationship between pH and three different digestive enzymes. Which of the following conclusions can be drawn from this graph? A. Digestive enzymes are most active in an environment with a pH of 7. B. Enzymes operate most efficiently within a certain range of temperatures. C. Enzymes are only able to operate in acidic environments. D. Each enzyme operates best within a certain pH range.
Answer:
A
Explanation:
Each enzyme operates best within a certain pH range.
Digestive enzymes are most active in an environment with a pH of 7 is the conclusions can be drawn from this graph.
What is enzymes?Enzymes are referred to as proteins which act as biological catalysts. Catalysts enhance the chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Each enzyme works within quite a small pH range. There is a pH at which its activity is greatest (the optimal 7 pH) because changes in pH can make and break intra and intermolecular bonds, changing the shape of the enzyme and, therefore, its effectiveness.

Although these organisms belong to the same phylum, they are classified as different -
A families
B species
C kingdoms
D orders
Answer:
A
Explanation:
Makes the most sense
Although these organisms belong to the same phylum, they are classified as different families. Thus, option A is correct.
What is family?The family structure that is being described in the description above is step family structure. The step family is being formed by which one family ends with divorce and the individual is likely to get remarried, creating a blended or step family that is associated with two families that are separated.
Family of choice refers to the concept of family is intended to capture the commitment of chosen, not fixed, care and support. A family of choice is also known as chosen family and found family. It is a family that is made up of intentionally by chosing the members for love and support rather than blood. Basically, family of choice is that one in which people chose their member intentionally.
Therefore, Although these organisms belong to the same phylum, they are classified as different families. Thus, option A is correct.

Select ALL the correct descriptions that help to define luminosity.
A. How much energy is emitted per second
B. How much surface area the object has
C. The amount of brightness of an object
D. The color emitted by the start
The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

Katie and her sister have entirely different features and traits. Katie has blonde hair and brown eyes, but her sister has red hair and blue eyes. What causes these variations in traits such as hair color,eye color,and height? A. Competition b. Offspring c.Alleles d. Fitness
Answer:
c.Alleles
Explanation:
Genes are the hereditable units that transmit the information needed to specify traits (such as hair or eyes color), from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.
Each chromosome carries specific genes that code for specific proteins that have specific functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But not all chromosomes carry the same gene sequences. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but in different alternatives.
Alleles are the different alternatives in which a gene might appear. By the process of natural mutation, a gene might change into two or more alternative forms that are called alleles. These alternative forms codify for the same trait expressing different phenotypes.
In the exposed example, alleles are responsible for the different phenotypes expressed by the girls. The alternative forms of the genes -the alleles- that codify or hair color and for eyes color, express either red or blonde hair, and either blue or brown eyes.
The final genotype and phenotype depend on the gametes that merge to form the zygote, and hence the new organism.

Which theory directly
contradicts the concept of
absolute zero?
A. Gravitational Theory
B. Kinetic Theory
C. Matter Theory
A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.
What theory directly contradicts concept of absolute zero?All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).
Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.
Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

Which choice gives the order of a chain of events that show cause and effect relationships that results from human activity?
A. increased carbon dioxide in the atmosphere; increased water vapor in the atmosphere; increase in severe storms; increase flooding
B. increased water vapor in the atmosphere; increase in severe storms; increased carbon dioxide in the atmosphere; increase flooding
C. increased water vapor in the atmosphere; increased carbon dioxide in the atmosphere; increase in severe storms; increase flooding
D. increased carbon dioxide in the atmosphere; increase flooding; increased water vapor in the atmosphere; increase in severe storms
Answer:
D
Explanation
carbon dioxide is enhanced by human activity as it icrease it leads to many consequences so B and C are canceled
increasing carbon dioxide does not increase the water vapor immediatly
so A is canceled
so the left answer will be D
The choice that provides the ordering of the chain of events should be option D where the carbon dioxide should be increased.
What is carbon dioxide?It should be treated as colorless and nonflammable gas at the normal temperature and the pressure. Also it comprise of one carbon atom and 2 oxygen atoms. Here it should be enhanced by the human activity due to which the flooding should be increased, water vapor is also increased also the storms too.
