Answer:
By extensively filtering the water in a lake or a bay they can clear it enough to increase light penetration thus affecting benthic macroalgal communities by facilitating growth. There are numerous examples of animals and plants that function as ecosystem engineers.
In ecosystems engineers by altering their receptive environment, invading species have the potential to play a dominant role as ecosystem engineers and can have an ecosystem-level impact by hindering or facilitating other species, whether invasive or native.
What are ecosystems engineers?Ecosystem engineers are organisms that alter the physical condition of biotic or abiotic materials to affect the availability of resources (other than their own) to other species. By doing this, they alter, preserve, or even create new environments.
They can clear the water in a lake or bay sufficiently to promote light penetration, which will influence benthic macroalgal ecosystems by promoting growth.
Therefore, there are many instances of plants and animals that act as ecosystem engineers.

What letters represent the four nitrogen bases in DNA?
Answer:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
Explanation:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
What is base-pairing rule?According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
The bases are Adenine, guanine, guanine, cytosine, thymine, adenine the string of their base pair would be Thymine, cytosine, cytosine, guanine, adenine, thymine.
DNA stands for Deoxyribonucleic acid. It is made up of two complementary strands. There are four nitrogenous base present in the DNA strand. These are-
Adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair with bases on the complemenatry strand just according to the Watson and Crick base pairing ( A=T, G ≡ C ). Uracil is another nitrogenous base. But it is present in RNA in place of Thymine.
Thus, bases found in the DNA are Adenine, thymine, guanine, cytosine.

If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answer:
A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.
The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.
Hence, the wide base shows higher population of younger age children and higher birth rate.

Scientific theories can change when new evidence is discovered and is supported and accepted widely. Which statement can possibly create a change in the cell theory?
a. A scientist discovers a new living organism with different cells.
b. A scientist discovers a new living organism with cells but no tissues.
c. A scientist discovers a new living organism that has no cells.
d. A scientist discovers a new living organism that has cells that work separately.
Answer:
c. A scientist discovers a new living organism that has no cells.
Explanation:
The cell theory is a widely accepted and globally recognized theory of living things. It was proposed in the 1830's by the collective effort of three scientists namely: Mathias Schleiden, Theodor Schwann and Rudolph Virchow. The cell theory is made up of three components as follows:
- All living things are made up of one or more cells.
- The cell is the basic and fundamental unit of life.
- All living cells comes from pre-existing cells.
According to this question, a new evidence that can possibly create a change in the cell theory is if a SCIENTIST DISCOVERS A NEW LIVING ORGANISM THAT HAS NO CELLS because all living organisms have been said to be made up of cells in the cell theory.

What molecule is removed during dehydration synthesis? *
a. Water

c. Sugar
d. Carbon
During dehydration synthesis, water molecule gets removed. The correct option is a.
What is dehydration?A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.
These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.
Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.

what caused a decrease of carbon dioxide in the biodomes air
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.
What are the factors responsible for decrease of carbon dioxide in the biodomes air?There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:
Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.
Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.
Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.
Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.
It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

DNA _____.
is a long, single chain of nucleotides
cannot determine behavior traits
contains coded information for the creation of proteins
is enclosed by a nuclear membrane in prokaryotes
Answer:
Answer:
The correct answer would be "contains coded information for the creation of proteins".
DNA or deoxyribonucleic acid is a polymer of nucleotides.
It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.
In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.
The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.
It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

Transpiration is the evaporation of water from the surface of a plant. Explain.
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.
