Which structure is highlighted?
a. anterior cavity
b. pupil
c. posterior cavity
d. iris lens
Answers
Option (c) Posterior cavity is the highlighted structure.
The area behind the lens that extends to the retina's location on the back side of the internal eyeball is known as the posterior cavity. The vitreous humor, a more viscous fluid, fills the posterior cavity.
The posterior chamber is a crucial component in the creation and movement of aqueous humor.
The posterior chamber receives the aqueous humor secreted by the ciliary body's epithelium, which then flows through the pupil and into the anterior chamber.
The anterior hyaloid membrane and all of the optical components behind it, including the vitreous humor, retina, choroid, and optic nerve, are located in the posterior segment, also known as the posterior cavity, which makes up the back two-thirds of the eye.
Hence, Posterior cavity is the highlighted structure.

Which of the following answers is NOT correct with regard to convection currents?
A. Convection currents in magma drive plate tectonics.
B.Convection currents in magma are a result of density differences.
C. Convection currents play a role in the movement of Earth’s inner core.
D. Convection currents in magma are caused by temperature differences.
Answers
Answer: C....Convection currents play a role in the movement of Earth’s inner core
The statement which is not correct with regard to convection currents is as follows:
Convection currents play a role in the movement of Earth’s inner core.Thus, the correct option for this question is C.
What is Convection current?Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.
The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.
Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.
Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.
Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.
Therefore, the correct option for this question is C.

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?
Answers
Answer:
epigenetics chamges take place.
Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.
Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.
Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.
What is the epigenetic pattern?Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.
Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.
Answers
Answer:
isotonic; the same rate
Explanation:
Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.
For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.
Which small-scale mutation would be most likely to have the least negative effect on the function of a protein?
A substitution of one base for another within the sequence
A base deletion near the start of a gene
A base deletion near the end of the coding sequence, but not in the terminator codon
A deletion of three bases near the start of the coding sequence, but not in the initiator codon
Answers
Answer:
substitution
Explanation:
has a chance to cause silent mutation, which doesnt do anything to a protein.
The small-scale mutation that would most likely have the least negative effect on the function of a protein is ; ( A ) A substitution of one base for another within the sequence.
A substitution of one base for another within the sequence of a protein will cause an insignificant/silent mutation within the protein sequence and this mutation will not be evident in the protein.
When a base is deleted either near the start of a gene or near the end of the coding sequence, it will have a significant effect because this will change the sequence of the DNA ( due to the deletion of at least one nucleotide ).
Hence we can conclude that the small-scale mutation that would most likely have the least negative effect on the function of a protein is ; A substitution of one base for another within the sequence.

Durning an experiment you need to keep everything the same but only change the certain things based on your theory.
