Explanation:
The independent variable would be us humans polutling the ocean with oil and other plastics destroying the coral reefs. The dependant variable is an abbrasive species of fish becoming overpopulated and killing all the fish that help the coral grow causing the coral to die. (independant variable basically means humans tampering with it causing the problem. dependent is naturally occuring humans cant control whether a fish overpopluates or not thats natural)

look at the picture below. what word describes what is happening to the nutrients and water in the biome?
Given what we know about the water cycle we can confirm that the process that happening in the biome is the process of condensation
Although the water cycle can be divided and subdivided into various processes, we can simplify it into four simple steps:
EvaporationCondensationPrecipitation CollectionThe one saw in the biome and one of the most essential parts of the cycle is condensation. It is the collection of water molecules into a single group that, when dense enough, fall back onto the earth as rainfall. In nature these take the form of clouds, meanwhile, in the biome, they appear as water on the sides of the container.

A student is conducting an experiment with biochemical reactions and notices that at high temperatures, the reaction rate decreases significantly.
Which statement best explains the decrease in reaction rate?
The bonds of the substrate were breaking.
The enzyme bonded with the substrate.
The enzyme denatured and changed shape.
The activation energy was increasing.
Answer:
The enzyme denatured and changed shape
Explanation:
Enzymes are proteins, which can only function properly within a certain range of temperatures- when things get too hot, proteins undergo a structural change and are considered to be 'denatured'. This means that enzymes will not be able to function properly under those high temperatures, because the substrate bonding site would no longer be the right shape for said substrate.
The statement best explains the decrease in reaction rate is the enzyme denatured and changed shape. Thus option 3 is correct.
What are enzymes?Enzymes are defined as a material that functions as a catalyst in living things, controlling the pace at which chemical processes take place without changing the substance itself.
There are six types of enzymes.

In human bodies, enzymes facilitate metabolic reactions. From breathing to digestion, they support.Health issues might result from having a too amount or too little of a certain enzyme. To help their bodies function as they should, certain persons with chronic diseases may need to take enzyme supplements.Thus, the statement best explains the decrease in reaction rate is the enzyme denatured and changed shape.

Define negative feedback in biology
Answer:
A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis
Explanation:
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances

How many seconds would it take DNA polymerase to replicate one set of human chromosomes (6,000,000,000 bytes long)
The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.
What is chromosome ?A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

what is true of a fossil that is classified as a transitional form?
Given our understanding of the situation, we can confirm that a fossil classified as a transitional form, will show characteristics both of its ancestors and of the descendants that derived from it.
Transitional fossils are just that, fossilized remains of a transitional phase of evolution. What this means is that as species evolve, there will always be a point in time where a species is at a halfway point in between the species from which it comes, and the species that it will become.
These fossils, due to being a halfway point, will have characteristics that belong to their ancestors, but also characteristics that belong to their descendants, which is only logical considering that evolution is a process that spans many generations, not something instant.

What are MAD (mitotic arrest deficient) proteins and when are they important in the cell cycle?
Answer:
The mitotic arrest deficient protein MAD2B (MAD2L2) is a member of a MAD family of proteins and shows 48% similarity to MAD2 (MAD2L1) [1], [2]. Both MAD2 and MAD2B can bind to the anaphase promoting complex or cyclosome (APC/C), which is a downstream target of the mitotic spindle checkpoint.MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
At the end of stage G1 and before S.Before anaphase in mitosis.DNA damage checkpoints in G1, S or G2.The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous chemical substances, other environmental effects, and age.
What are the factors that affect gene expression?The level of transcription is where the majority of control over gene expression is exerted, and this is mostly due to the fact that proteins bind to certain locations on DNA.
It is possible for environmental elements such as nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens to have an effect on which of an animal's genes are expressed, which in turn has an effect on the animal's phenotype.
