Answer:
How does RNA polymerase know where to start transcribing a gene?
To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. ... A promoter contains DNA sequences that let RNA polymerase or its helper proteins attach to the DNA.
TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
What is transcription?Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form.
The TATA box is able to define the direction of transcription and also indicates the DNA strand to be read. Proteins called transcription factors can bind to the TATA box and recruit an enzyme called RNA polymerase, which synthesizes RNA from DNA.. The TATA box marks a point just before the point at which transcription begins, so that RNA polymerease transcribe the correct region of DNA molecule.

rainfall.
Deer do not adapt well in cooler environments.
There was significantly more hunting in 2011.

What's a representation of all the producer and consumer relationships within a community or ecosystem?
A. food pyramid
B. food chain
C. food web
D. food log
Hello!
Let's look at some definitions!
A food pyramid is levels of predators, in an pyramid shape to show the successive.
That does not match the definition your question provided, so we can move on.
A food chain is a series of animals who depend on each other for food/buisness.
Again, it does not match, this is a series, not an entire ecosystem.
A food web is a connection of food chains, which show the entire relationships of an ecosystem.
This definition is fairly close to the listed definition, lets keep this in mind.
A food log is a chart of what you eat each day.
Trick answer! This has nothing to do with the subject.
Given these choices, the correct answer is:
Food Web

Describe how a protein would be changed if a base sequence mutates
from GGA to TGA.
Answer:
The protein would contain threonine instead of proline
Explanation:
The shape of the protein may be changed when a base sequence mutates from GGA to TGA.
What do you mean by Mutation?A Mutation may be defined as a sudden, stable, and inheritable change that occurs in the genetic material of an organism.
The amino acid sequence would be different, as GGA codes for Glycine, while UGA or TGA codes for stop codon which terminates the process of protein synthesis.
The protein which may be synthesized may not work correctly. In other words, the protein would be functional less.
Therefore, the shape of the protein may be changed when a base sequence mutates from GGA to TGA.

What is the main difference between primary succession and secondary succession?
Answer:
Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.
Explanation:
Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.
Hope this helped!
Answer:
Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)
On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition
Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

Parasitism is a refered to as a symbiotic relationship that exists between organisms such one organism, which is known as the parasite, either lives on the other organism which is called the host or lives inside it and causes the host harm.
In this case, the parasite benefits at the expense of the host. Examples of parasites include tick, fleas and tapeworms.
With regards to the question, the tapeworm causes people harm and benefits at the expense of its host.

Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule synthesized by plants using that product
Answer:
(A) nitrates—proteins
Note: The question is not complete. The complete question is given below:
Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule
synthesized by plants using that product?
(A) nitrates—proteins
(B) ammonia—carbohydrates
(C) nitrogenous wastes—nitrites
(D) atmospheric nitrogen—nitrates
(E) atmospheric nitrogen—ammonia
Explanation:
The nitrogen cycle refers to the cycle through which nitrogen is transferred for use through both living and non-living things, involving the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is especially important for living things because nitrogen is essential for the formation of amino acids which form proteins.
The nitrogen cycle occurs in five stages:
1. Nitrogen fixation - Nitrogen gas from the air is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds.
2. Nitrification - Ammonia is converted to nitrates by nitrifying bacteria in the soil.
3. Assimilation - Plants absorb nitrates from the soil and use them to make proteins. The plant is then eaten by an animal and are used to produce animal protein.
4. Ammonification- Decomposers break down the bodies of dead organisms, urine and faeces converting them to ammonia in the soil, which is then converted to nitrates by nitrifying bacteria.
5. Denitrification - Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air.
From the above stages and the options provided, the correct option is A - nitrates from the nitrogen cycle is converted to protein by plants.
