Dichotomous keys can only be used if the name of the species is known.
Answers
The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.
What is a Dichotomous key?A dichotomous key might be considered a significantly useful tool to classify organisms.
The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Each time you choose an option, it leads you to the following description, which gets more specific each time.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies.
You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

One person pulls on a rope with a force of 400 N to the right. Another
person pulls on the opposite end with a force of 600 N to the left. What is
the net force?
Answers
Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.
What is Net force?Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.
If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.
Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.
As a result of these forces, the net force applied on the rope can be calculated by:
Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction
Net force = 600N (force applied to the left) - 400N (force applied to the right)
Net force = 200 N and the direction will be left as the magnitude is more in left direction than right
Therefore, the correct option is A.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Simply when layers of eroded material pile to create new landforms. For example, coastal deposition is how beaches are formed.
The geological process of deposition involves the addition of sediments, soil, and rocks to a landform or landmass. when eroded debris is piled up in layers to produce new landforms.
What is deposition?A deposition is testimony made under oath and taken down in writing by an authorized officer of the court, typically in an out-of-court setting and before trial.
Depositions are usually taken from key witnesses, but can also involve the plaintiff or defendant, to give the involved parties a fair preview of all the evidence.
The individual making the deposition is known as the deponent and false statements can carry civil and criminal penalties.

1) Why does the addition of dideoxynucleotides to the DNA sequencing reaction cause DNA synthesis to stop after the modified nucleotide is added?
A)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'OH group to attach the next nucleotide being added.
B)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'PO4-group to attach the next nucleotide being added.
C)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added.
D)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'PO4-group to attach the next nucleotide being added.
Answers
In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.
Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.
The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.
In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.

Answer:
0.9420m/s north

Which term can avoid traveling through a solid, a liquid, or a gas?
Answers
The term that can avoid traveling through a solid, a liquid, or a gas is "electromagnetic radiation" or "light."
Electromagnetic radiation: Electromagnetic radiation refers to the propagation of energy in the form of waves or particles through space. It includes various types of radiation, such as visible light, radio waves, microwaves, X-rays, and gamma rays.Traveling through solids: Solids have a tightly packed arrangement of atoms or molecules, which makes it difficult for electromagnetic radiation to pass through them. The particles in solids interact with the radiation and absorb or scatter it, preventing its transmission.Traveling through liquids: Liquids have a less rigid arrangement of particles compared to solids. While some electromagnetic radiation can pass through liquids, it may be partially absorbed or scattered due to interactions with the liquid molecules.Traveling through gases: Gases have widely spaced particles, allowing electromagnetic radiation to travel more freely compared to solids and liquids. However, certain gases can still interact with specific types of radiation, such as absorbing certain wavelengths or causing scattering.Overall, electromagnetic radiation, or light, has the unique property of being able to propagate through a vacuum, which means it can travel through space where there is no matter present, as well as through various mediums, including gases, liquids, and solids.

What is the Big bang?The big bang may be defined as the cosmic explosion that significantly marked the initiation of the universe according to the big bang theory. The origin of the universe is explained by the Big Bang theory.
At initial, the whole universe appeared like a black hole where no life is present. It was all the dark around each and every corner. The universe was an infinite stretch of ultrahot, dense material and everything consisted of empty space.
Before the big bang, the universe was almost infinitely small, dark, and a size less than a trillionth of a second. It was a period of inflation which is followed by a more catastrophic event which was violent, and known as the period of expansion.
