Answer:

The Answer is Y

Explanation:

Y is the arrow pointing towards the center of the circle and the centripetal force always goes toward the center of the circle.

The arrow that represents the centripetal force responsible for this motion is : Arrow Y

Arrow Y points towards the center of the circle which is the same direction as the centripetal force acting on body whcih follows a curved path. centripetal force moves to the center of the circle ( i.e circular path ) of the object.

Hence we can conclude that the arrow that represents the centrpetal force responsible for this motion is Y

Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions.

Explanation:

The statement indicating that water can enter the skin cells of a dead body placed in water, due to passive transport is TRUE.

Passive transport refers to the movement of substances in favor of a concentration gradient through a membrane, and osmosis is a type of passive transport by which water (H2O) molecules move through a membrane in favor of this gradient.

In conclusion, the statement indicating that water can enter the skin cells of a dead body placed in water, due to passive transport is TRUE.

Explanation:

GG.

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

It helps you understand how life forms and what it takes for life to develop as well as the changes through this life cycle

Explanation:

Knowing information about embryo development is important because it helps us to understand how an organism grows and develops from a single cell into a complex being.

An embryo is the stage of development that follows fertilization and begins when the zygote, a single cell formed by the union of a sperm and egg, begins to divide and differentiate into the various cell types that will make up the organism.

This knowledge can be used in various fields, such as reproductive medicine, to help improve fertility treatments and increase the chances of successful pregnancies. It can also be used in fields such as genetics and evolutionary biology to understand how traits are inherited and how species have evolved over time. Understanding embryo development can also provide insights into the causes of birth defects and developmental disorders, and help researchers develop treatments or interventions to improve the health and well-being of individuals.

Select statements true of fracture zones. Choose one or more:

A. Earthquakes can occur along fracture zones.

B. Fracture zones are situated perpendicular to mid-ocean ridge segments. C. New crust is formed via seafloor spreading along fracture zones.

D. Fracture zones can act as transform boundaries between two actively spreading ridge segments.

Fracture zones are situated perpendicular to mid-ocean ridge segments.

Fracture zones are a consequence of plate tectonics, they are an oceanic feature that is linear and sometimes travels thousands of kilometers due to the action of displaced mid-oceanic ridge axis segments. These zones are seismically inactive since the two fracture zones move in the same direction.

These fracture zones are important since by studying them it is possible to determine the direction and speed that their movements can have.

Therefore, we can confirm that fracture zones are situated perpendicular to mid-ocean ridge segments.

Answer:

Retinoblastoma is more common in people due to the mutation of RB gene in them.

Explanation:

Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.

When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.

Explanation:

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.
