Answer:
That's how negative transcription factors work in plant and animal cells. Hope this helps as well. Negative transcription factors (repressors) prevent transcription of certain pieces of DNA. One example, is the suppression of the lac operon.
which of these describes what happens when the temperature of an object increases
Answer:
kinetic energy
Explanation: When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

A dark spot appearing from time to time on the sun's surface
Answer:
A brief eruption of intense high-energy radiation from the sun's surface
Explanation:
Sometimes the sun experiences a magnetic storm that appears as a bright spot on its surface. Through an explosion, there is a release of intense high-energy radiation. These explosions are called solar flares and often happen within magnetic fields, just like sunspots.

C. term used to differentiate different ecosystems and habitats from each other.
D. term scientists use to describe an ecosystem that has too many species to count.
Biodiversity can be defined as the variety of organisms on Earth in a particular habitat or ecosystem.
What is biodiversity?Biodiversity is coined from two words namely:
Bio meaning lifeDiversity meaning varietyThis means that biodiversity refers to the number and variety of species of plant and animal life within a region or habitat.
Different habitats or regions have varying biodiversity meaning that a region is more bio-diverse than others.
Therefore, biodiversity can be defined as the variety of organisms on Earth in a particular habitat or ecosystem.

What do we call the process of
water turning into an atmospheric gas?
A. freezing
B. evaporation
C. perspiration
Answer:
B
Explanation:
Evaporation
The water turned into gas which is called evaporation
Answer:
Evaporation :)
Explanation:
An example is water and a hot pot. When the water starts to boil, it slowly starts turning into a gas. As this continues, the water will continue to disappear. If you have a lid on the pot, you will find the water droplets on it. The way the water got there was by turning into a gas or evaporation :)

How the plate tectonics play a role in the creation of plutons?
Answer:
The majority of granitic magmas are formed by melting near the base of the continents. The magmas slowly rise through the crust like great balloons. They solidify near the surface to form gigantic bodies of igneous rock called plutons, which are exposed later when uplift and erosion remove the overlying rock.

An illustration of how a particular DNA mutation will most likely affect the polypeptide produced shown. What type of mutation is illustrated?
Answer:
Deletion i think
Explanation:
Several kinds of mutations including deletions, point mutation, insertion and translocation can happen.
What are DNA mutations?DNA mutations are irreversible alterations to a gene's DNA sequence. The degree of mutations varies. Some have an influence on how a cell or a whole organism works, whereas others have zero effect. The quantity of DNA changed by mutations varies as well. They can range from one nucleotide to huge chromosomal regions. DNA mutations can occur as follows:
Inherited mutations: Parents who have mutations can transmit them on to their children. Germline mutations: are found in every cell of a person. De novo (new) mutations: develop as a result of chance inside one or very few eggs or sperm, or shortly after fertilisation.Acquired mutations: Environmental substances known as mutagens can affect DNA.Mutation types:
Insertion/Duplication/Deletion: the insertion or removal of nucleotides from the DNA sequence. They can be as little as a single nucleotide or as vast as a chromosome with tens to hundreds and thousands of nucleotides.Point mutation: substitution of one nucleotide for the other. For instance, an "A" becomes a "T."Translocation: the transfer of a DNA fragment through one chromosome to the other.Inversion: a 180° flip of a Segment of DNA that causes it to be inverted in comparison to its original structure.Therefore, the mutations in DNA can be of several types.
