An ecosystem that retains structure & continues normal functions even when environmental conditions change is?
Resilient
Resistant
Reductive
Reconciled
Answer:
Resistant
Explanation:
A good aspect of the ecosystem can either be resistant or resilient when there is a disturbance or a form of deviation from the regular occurrence in the ecosystem structure, function, or both.
For an ecosystem to be resistant means it maintains structures and goes on with normal functions despite the disturbance or alteration in environmental circumstances.
Hence, in this case, an ecosystem that retains the structure and continues normal functions even when environmental conditions change is RESISTANT.

Such type of organisms typically synthesizes their own food with the help of the photosynthesis process. These organisms derive energy by consuming inorganic nutrients and matter.
Heterotrophs are those organisms that consume readymade food synthesized by autotrophs in different modes.

Answer:
Angiosperms have small pollen grains that spread genetic information from flower to flower. These grains are much smaller than the gametophytes, or reproductive cells, used by non-flowering plants. This small size allows the process of fertilization to occur quicker in the flowers of angiosperms and makes them more efficient at reproducing

Trisomy X, also known as triple X syndrome and 47,XXX, is characterized by the presence of an extra X chromosome in each cell of a female. Those affected are often taller than average.
Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby.

Some populations of Atlantic tomcod fish have an allele that makes the fish resistant to toxic pollutants called PCBs. Tomcod populations in several rivers were analyzed for the presence of this allele. Each river had varying levels of PCB pollution. Which of the following results would best support the conclusion that natural selection is influencing the presence of this allele in the tomcod populations?
A. All of the tomcod in each of the rivers have this allele.
B. The percentage of tomcod with this allele remains the same from year to year in each river.
C. The rivers with high PCB levels have larger percentages of tomcod with this allele than the rivers without PCBs.
D. Eggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.
Answer:
D
Explanation:
Hope it helps#CARRYONLEARNINGEggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.
What is Tomcod populations?A benthopelagic piscivore, the Atlantic Tomcod is also known as frostfish or tommy cod. Although large ones are allegedly caught less frequently than they once were in estuary rivers, it is still abundant around the seacoast.
Although anadromous, Atlantic tomcod do not migrate very far between fresh and salt water. In shallow brackish or fresh water, sand and gravelly bottoms are where eggs are laid. Masses of eggs sink to the bottom.
Within 24 hours of hatching, newly hatched larvae swim to the surface to breathe surface air before their pneumatic duct closes. Young-of-the-year may spend their first spring and summer in fresh or barely brackish water, but they eventually move into estuaries and nearshore waters.
Therefore, Eggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.

X + H20 → Y + O2(what would be y in this equation ?)
Answer:
y. 2. • CxHy + O2 → x CO2 + y/2 H2O. Combustion Problem. Erythrose is an important mono-saccharide that is used in chemical synthesis. It contains Carbon.
Explanation:
In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction, here Y is the glucose, and this X is carbon dioxide, and this is a reaction of the photosynthesis.
What is photosynthesis?During photosynthesis, the energy from light is used to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere as a waste product, while the hydrogen ions are used to create a chemical gradient across the thylakoid membrane within the chloroplast. This gradient is then used to power the creation of ATP, the energy currency of cells, as well as to reduce carbon dioxide to form organic molecules, such as glucose. The overall equation for photosynthesis is:
6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
Hence, In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction; here, Y is the glucose.
