Answer:
True
Explanation:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

which of the sediments shown below were most likely deposited by a glacier
Please HELP
Answer:
D
Explanation:
Hopefully this helps
Directly deposited sediments by water are often sorted and show layers, of the sediments left behind by glaciers, hence option D is correct.
What sediments are deposited by a glacier?Additionally, it appears that the glacier debris is unsorted a diamictite, a sedimentary rock made up of unsorted grains, is produced when this mass of sediment is cemented into a rock.
Till is the name for the loose silt in its unlithified state, they are distinguished by a lack of stratification and a diverse variety of sediment sizes, ranging from boulders to clay.
Therefore, a tillite is a more precise term for an unsorted sedimentary rock that contains grains that were deposited by ice, hence option D is correct.

What is the total number of protons, neutrons, and electrons in cadmium, Cd, atom that has a mass number of 112?
Answer:
number of protons = 48
number of neutrons = 64
number of electrons = 48
Explanation:
The mass number of an atom is the sum of the number of protons and neutrons in the nucleus of the atom. Hence, for Cadmium;
mass number = proton number + neutron number = 112
Cadmium has an atomic number of 48. The atomic number is the number of protons found in the nucleus of the atoms of an element. Hence, the number of protons in an atom of Cadmium is 48.
proton number + neutron number = 112
proton number = 48, hence
48 + neutron number = 112
neutron number = 112 - 48 = 64
Also, for a neutral atom of an element, the number of protons and electrons must balance. This means that for a neutral atom of Cadmium with a proton number of 48, the number of electrons will also be 48.
In summary, for cadmium:
number of protons = 48
number of neutrons = 64
number of electrons = 48
The mass number of an atom can be seen as the sum of the number of protons and neutrons in the nucleus of the atom. And the number of protons is always the same as the number of electrons
The number of protons = 48
The number of neutrons = 64
The number of electrons = 48
Since the mass number = proton number + neutron number = 112.
And cadmium has an atomic number of 48.
The atomic number is the also regarded as the number of protons found in the nucleus of the atoms of an element.
Then the number of protons in an atom of Cadmium is 48.
Since proton number + neutron number = 112
48 + x = 112
x = 112 - 48 = 64
Therefore the number of neutron is 64.

Kingdom Protista contains mostly unicellular eukaryotes. However, a few are multicellular.
Some protists reproduce sexually using gametes, while others reproduce asexually by binary fission.
Some protists are autotrophic, while others are heterotrophic.
Protists are eukaryotic, as their cells have a nucleus and other membrane-bound organelles.

What are the characteristics of the kingdom Protista?Kingdom Protista is one of the kingdoms that has been constituted of the organisms that have single-celled and multicellular bodies and are classified under the eukaryotes.
They can show both the modes of reproduction as it includes alternation of generations, conjugation, and binary fission as seen in amoebas and Euglena.
They are autotrophic as they can produce food using chemosynthesis and photosynthesis as seen in Spirogyra. They also are heterotrophic and include sporozoans, paramecia, molds, etc.

Describe at least two other experiments that could be done to verify that chromosomal gene editing occurred in the bacteria.
The two ways by which we can detect that gene editing have occurred in the bacteria are;
A) WESTERN BLOT; Here,the gene that is edited will not be able to synthesize the protein.With this,if we do western against the already edited protein,no band will eventually appear in the western blot,and this indicates/confers that the gene have been edited.
B) PCR FOLLOWED BY SEQUENCING; IN PCR,there is amplification of the region with the use of flanking end primers that is edited.
However,mean primers will actually be used in a way that one primer is upstream to site of editing and the other primer to the downstream.
From this stage,the PCR product that is amplified will be sent for sequencing,and this sequency result will further confirm if the gene has been edited or not edited.
Restriction enzyme can also be used if the place where the gene has been edited is known.
If actually the gene has been edited,the nucleotide sequence will get changed.Having to choose such enzyme that cut only one's wide type wild type DNA but not actually gene that is edited,the result will further be compared inorder to confirm whether the gene has been edited or not.
The two experiments that can be done to detect gene editing including
Western blot and PCR(polymerase chain reaction)
DNA contain all the genetic properties of a cell and comprises of nucleotides with unique protein(amino) sequences. Western blot helps to detect specific protein through the sequences from a protein sample and helps to detect if editing took place.
Polymerase chain reaction(PCR) helps in the amplification of DNA which
helps to verify where editing took place if any.

When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer, DNA polymerase, and _____.
a. Forward and reverse primers
b. Forward or reverse primers
c. Forward and reverse probes
d. Forward or reverse probes
Answer:
b. Forward or reverse primers
Explanation:
Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.
When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer, DNA polymerase, and forward or reverse primers.
Sanger sequencing refers to a laboratory procedure that's used in the determination of DNA sequence by using dideoxynucleotides. Sanger sequencing is also known as dideoxy sequencing.
For Sanger sequencing to work, one needs two pieces of information that will be used to apply the strategy of sentence game to the sequencing of DNA. It should be noted that forward or reverse primers are required for the reaction.
