The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle. As subduction occurs, crust closer to a mid-ocean ridge moves away from the ridge and toward a deep-ocean trench.
Perfect flowers have both male and female parts. The male part is called the _____ and the female part is called the _____.
What is the term that scientists use when comparing the properties of solids, liquids and gases?
Solids,liquids and gases are all made of atoms and have structural molecules.
The term that scientists use when comparing the properties of solids,liquids and gases are' States Of Matter.'
Which is it can be said Matter in our surroundings.
Hi bro, remember me I just changed my profile pic. Anyway here is the answer. A Representation of the Solid, Liquid, and Gas States. A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance
Hope this helps!
Please give brainliest bro!

In your own words, explain the role of scientific investigation in the development of the Theory of Adaptation.
The scientific theories can be framed on the basis of scientific evidence as well as their proofs.
To frame any scientific theory one has to follow the scientific procedure to reach the conclusion one of which is an investigation to provide the best evidence to support the theory.
The theory of evolution was proposed by Charles Darwin which stated that organism evolves from ancestors or descent with modifications. In favor of his theory, he presented the remnants of the past organism as well as the collected specimens form his voyage.
The scientific investigation is the systematic approach of the scientists to answer the questions about the world. It is applied almost all of the theories including the Theory of Natural Selection. Darwin's theory of evolution is a result of scientific investigation. In this theory, they investigate by observing the distribution of species.
Robert Hook's discovery helped scientists learn more about _____. microscopes
robert hooks discovery help scientists learn more about cells.
Molecules that are not able to independently diffuse across a membrane may still move down their concentration gradient by
Plants which produce their gametes in flowers are called: I know it's not gymnosperms. So which one is it? angiosperms
Plants which produce their gametes in flowers are called angiosperms.( first choice)
1. The snow is making driving conditions very dangerous. But I must still go out and vote even though my candidate has no chance of winning. 2. Smallpox is no longer a threat to anyone in the United States. And the vaccination against it is unpleasant and, in rare cases, lifethreatening. We were wise when we ceased the routine vaccination of our children.
A statement can contain one argument, more than one argument or no argument.
Argument are intended to determine the degree of truth hence enabling a conclusion to be made. It contains one or more premises and only one conclusion.
A premise is the statement in the argument that provides reasons to support a conclusion.
In the first statement, there is no argument. This is because there is neither a premise nor a conclusion
The second statement has a conclusion(the last sentence) and two premises(first two sentences) therefore it is an argument.
What was Marshall Nirenberg and Heinrich Matthaei’s contribution to our current understanding of the genetic code? discovery of codons
discovery and extraction of DNA
creation of a model of DNA
creation of Photo 51
The correct answer would be discovery of codons.
Marshall Nirenberg and Heinrich Matthaei experimentally decoded the triplet codons with the help of synthetic homopolymer of nucleic acid.
They used synthetic RNA which is made up of uracil units only that is, polyuridycil acid (poly-U) and a cellular component which could translate protein.
The poly-U RNA results in the formation of polypeptide chain entirely consisted of phenylalanine. Thus, UUU codes for phenylalanine.
Similarly, other codons were also deciphered.
