which type of mutation is being shown.
Original sequence
deletion insertion substitution
deletion insertion substitution
deletion insertion substitution
Answer:
A. ✔️Substitution
B. ✔️Insertion
C. ✔️Deletion
Explanation:
In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.
Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.
Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.
In genetics, there are: Substitution, Insertion and Deletion mutations.
Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.
Answer:
A. Substitution
B. Insertion
C. Deletion
Explanation:
A. There is a replacement in C G there is A T.
B. There is one more base.
C. There are 8 base there should be 9.

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light
Record the mass of the object based on the reading from the triple-beam balance. The mass of the object is ____ grams.
Hello!
[tex]\large\boxed{167g}[/tex]
Looking at the balance, we see that:
The middle beam reads 100g.
The top beam reads 60g.
The bottom beam reads 7g.
Add all of the numbers together to get the total mass:
100 + 60 + 7 = 167g.
The mass of the object is 167 grams.
Explanation:
A triple beam balance is a mass measuring instrument used in labs to measure the mass of a substance. It unit in which it measures is grams. It consists of three beams which are: The middle beam has Increments of 100 grams The front beam has Increments from 0 grams to 10 grams The farther beam has Increments of 10 gramsGiven :
Readings of all the scales of three beams of the triple beam balance of an object.
To find :
The mass of object whose reading on triple beam balance is given.
Solution:
Middle beam reader at 100 grams
Front beam reader at 7 grams
Farther beam reader at 60 grams
The mass of object:
[tex]100 grams + 7 garms + 60 grams = 167 grams[/tex]
The mass of the object is 167 grams.

Which of the following is an indication of a physical change?
O A. The formation of a new substance
O B. Giving off a smell
O C. A change in the shape of a substance
O D. The production of gas and heat
Answer:
A change in the shape of a substance
Explanation:
Because when ths shape of a sunstance changes , its physical appearance changes .A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
Which screw would create a strong hold?
A: The screw with 9 wraps.
B: The screw with 2 wraps.
C: The screw with 10 wraps.
D: The screw with 6 wraps.
Answer:
The screw with 10 wraps is the correct answer
Explanation:
The screw with 6 wraps would create a strong hold.
What do you mean by screw?The strongest member of the family of wood screws is a lag screw. It is a reliable and sturdy fastener that frequently has a square head or an externally powered hex drive.
In general, lag screws are significantly stronger and heavier than standard wood screws. They have a tapered point and coarse threads.
Thus, The screw with 6 wraps would create a strong hold.

______elements that have a longer half-life are more _______ than those that have a shorter half-life.
Answer:
Radioactive elements
Stable
Explanation:
Radioactive elements that have a longer half-life are more stable than those that a shorter half-life.
Half-life is the time taken for half of a radioactive element to decay by half of its original composition.
Now, if a substance have a long half-life, it is more stable and takes time to break down. For atoms with a short life, they are highly unstable and breaks down readily and easily.

if the atomic mass is 14 and the atomic number is 7,how many neutrons do you have?
Answer: 7 neutrons
Explanation: Atomic number refers to the number of protons in the nucleus of the atom. Also you can treat atomic mass as how many particles (protons and neutrons) are in the nucleus of the atom. So for this problem:
14 particles - 7 protons = 7 neutrons (and we know all that's left over is neutrons because we subtracted all the protons)
2. How can glass be a liquid if it's so hard?
Explanation:
Glass is not a liquid in the strictest sense of the word. But it is also not a standard solid. The chemistry of glass is complex and research is ongoing, but the current consensus is that glass is a phase of matter all its own, known as an "amorphous solid". Scientists refer to any amorphous solid as a "glass". Glass transitions are highly complex and cannot be treated in the same way as traditional phase transitions.
Answer:
It's a liquid state before its cooled.

Why are ocean currents important to coastal regions?
Answer:
Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.
Explanation:
Ocean currents are important to coastal regions for a number of reasons.
What are the importance?Distribute heat. Ocean currents distribute heat around the globe, which helps to moderate the climate in coastal regions. For example, the Gulf Stream brings warm water from the Gulf of Mexico to the coasts of Europe, which helps to keep Europe's climate warmer than it would be otherwise.
Transport nutrients. Ocean currents transport nutrients from the ocean's depths to the surface, which supports marine life. For example, the California Current brings nutrients from the deep ocean to the surface, which supports a rich marine ecosystem off the coast of California.
Diversify marine life. Ocean currents help to diversify marine life by transporting different species to different parts of the ocean. For example, the Kuroshio Current brings warm water from the western Pacific Ocean to the eastern Pacific Ocean, which has helped to diversify the marine life in this region.

10. The molar mass of CS2 is 76.14 g/mol. How many grams of CS2 are present in 10.00 mol?
Answer: C
Explanation:
There are 761.4 grams of CS2 in 10.00 mol.
To calculate the amount of grams present in a given amount of moles, the molar mass of the substance must be used, as follows:
[tex]m = MM \times mol[/tex]
In this way, just perform the following operation:
[tex]m = 76.14 \times 10[/tex]
[tex]m = 761.4 grams[/tex]
Thus, there are 761.4 grams of CS2 in 10 mol of the substance.
