Lakes, rivers, or springs can form when
Answer:
A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. In most landscapes the land is not perfectly flat—it slopes downhill in some direction.
Lakes can be formed when glaciers melt, craters from meteorites or rivers.
springs when rainwater or groundwater is heated by magma underneath Earth's surface.

Cohesion and adhesion are responsible for which of the following concepts?
Answer:
hydrogen bonding. In cohesion the water's hydrogen bonds make water self-sticky, it beads up. In adhesion water has the ability to climb up the wall of any container it is in.
Explanation:
The force of Gravity pulls the water towards the ground ,then why does it move against this gravitational force in a plant?????
I don't understand what do you mean exactly... But that what I've got...
1. If your question why water comes up in the plant it will be because it goes to leaves of the plant to feed the flower. It moves up by using the stem...
2. But if you mean why gravity force pull water down to the flour and it will come up inside the plant so the answer will be because there are a lot of parts of the plant that needs water.... And actually food that leaves are making for the plant will come to the roots again to make them stronger.
Earth's atmosphere is made up of mostly nitrogen (78%) and oxygen (21%); however, there are other gases in smaller amounts, like argon, carbon dioxide, neon, helium, hydrogen, and more. If there was an increase of carbon dioxide in the atmosphere, how would this affect temperature? A) The temperature would increase globally. B) The temperature would decrease globally. C) Temperature doesn't relate to the composition of the atmosphere; it has to do with the sun's rays. D) The temperature would not be affected since carbon dioxide is only one component in the atmosphere. HELP plssssss
Answer:
A
Explanation:
If there is an increase in the carbon dioxide concentration in the atmosphere, this will affect the temperature of the atmosphere. This will increase the temperature globally. Thus, the correct option is A.
What is Global warming?Global warming is a phenomenon in which the earth's average temperature has risen due to increased amounts of greenhouse gases. Greenhouse gases include carbon dioxide, methane and ozone which trap the incoming radiation from the sun.
Global warming has led to an increase in the global temperature. This has resulted in an increase in the melting of glaciers, which have led to an increase in the global sea level. This could have devastating effects on the coastal regions and species living in different environmental conditions.
Therefore, the correct option is A.

The presence of which of the following cell structures would tell him that
the cell is eukaryotic?
A. Nucleus
B. DNA
C. Cytoplasm
D. Ribosomes
The presence of nucleus would tell him that the cell is eukaryotic.
Eukaryotic cells are all those cells in whose cytoplasms a well-defined cell nucleus can be found, which contains most of its genetic material (DNA).
In this they differ from prokaryotic cells, which are much more primitive and whose genetic material is dispersed in the cytoplasm.
Eukaryotic cell is characterized by having within it the hereditary genetic material (DNA) of the organism and by having a complex structure composed of organelles that fulfill different essential functions in the cell.
Cell nucleus being the cell structure that contains the genetic material of the living being (DNA), and it is where the various functions of the cell are controlled and regulated and is covered by a nuclear envelope.
Therefore, we can conclude that the eukaryotic cell is one that has a defined nucleus, the cell nucleus is the cellular structure that distinguishes it from prokaryotic cells, where cellular activities are governed.

What phase of mitosis is shown in the diagram below?
☆
A. Anaphase
B. Telophase
C. Metaphase
D. Prophase
The given diagram shown here is representing prophase of Mitosis. The correct option is D.
What is Prophase?Prophase is the first step of cell division in both mitosis and meiosis. When the cell enters prophase, DNA replication has already started after interphase. The key occurrences in prophase are the condensation of the chromatin reticulum and the removal of the nucleolus.
Anaphase: Sister chromatids are pulled apart towards opposite poles of the cell by spindle fibers.
Telophase: Two daughter nuclei start to form as the chromatids reach the poles, and the nuclear envelope begins to reassemble.
Metaphase: Chromosomes align at the equator of the cell, with spindle fibers attached to their centromeres.
Prophase: Chromosomes condense, the nuclear envelope breaks down, and spindle fibers start to form.
Therefore, the correct option is D.

1. DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.
and this is for biomed science pltw and also he said that to use your our words too.
Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesnt mean that they were actually there of guilty. For example, a hair of Person A cound be carried over to another scene on Persons B's clothing.
DNA evidence analysis is an imperfect science because DNA is a very unstable and degradable molecule in the environment, furthermore, an DNA evidence analysis may present DNA molecules that are unrelated to the purpose of the analysis.
A DNA evidence analysis aims to:
Find biological traces in one location.Determine those responsible for activities carried out in that location.Determine the genetic makeup of a living being.This type of analysis is usually done in a place where there was a crime and it is necessary to do a DNA analysis to identify the culprits and victims.
The problem with this analysis is that DNA is a molecule that degrades quickly when outside the body. In addition, a location may have a very large variety of DNAs, which may belong to living beings unrelated to the crime, or to the purpose of the analysis.

What contributes to water's unique properties as a universal solvent, temperature moderator, and cohesive behavior? Hydrogen is a special element that does not have neutrons. The oxygen atoms of water molecules attract electrons more than hydrogen atoms. The properties are related to the crystalline structure of liquid water. The properties are related to the high electronegativity of hydrogen atoms. i think is B
Answer:
The oxygen atoms of water molecules attract electrons more than hydrogen atoms.
Explanation:
The uniqueness of water as a chemical substance is attriuted to its unique properties. These properties include being a universal solvent, having a high specific heat (temperature moderator), cohesive and adhesive nature etc.
This wonderful properties of water is due to its POLAR nature, which is when a substance has both positively and negatively charged parts to it. This is possible because the oxygen atoms (O) of water molecules attract electrons more than hydrogen atoms (H).
This POLARITY of water molecule is responsible for the HYDROGEN BONDING between water molecules and hence, contributes to the properties of water mentioned in the question (universal solvent, temperature moderator, and cohesive behavior)
