Which of the following is TRUE about the movement of earth's plates?
A. They do not move because they sit on a layer of solid rock
B. They move along with the layer of slightly softened rock below them
C. They move by floating on a layer of completely melted rock below them
D. They do not move until the solid rock layer beneath them temporarily melts and moves

Answers

Answer:

c

Explanation:

the tectonic plates or the crust of the earth sit on molten rock moving across the planet with causes the plates to move causing things like earthquakes and volcanos

Movement of Earth's plate can be due to many reasons and can cause many disasters. They move along with the layer of slightly softened rock below them

What is the 3 causes of this movement?

Earth's plates move due to the intense heat in the Earth's core. This causes the movement of soften rock in the mantle layer.

It moves in a convection cell pattern that forms by rising of warm, cooling and then sinking down of material.

The Earth's plates move by floating on a layer of completely melted rock below them.

Thus, the correct option is B.

Containers of ice cream are sold by volume, not by weight. Some ice cream manufacturers pump air into the ice cream before packaging it. Why does this practice make the ice cream more expensive to the consumer?

Answers

Ok so say a pint of ice cream is 7 dollars. And we have two different brands. Same price, same flavor, same package. One pint is filled to the top and is very dense. The other is filled an inch away from the top and is light and easy to scoop through. In processing they both were filled to the top but the lighter ice cream had air pumped into it. This air settles at the top as the air is less dense than the ice cream and still gets trapped in the ice cream as well. This costs the company nearly nothing to do and nearly doubled the mass of the ice cream in production. Leading to them saving a lot of money while charging the same price. Technically this brand is more expensive because you are getting less than what you are paying for.

explain the absorption of mineral by root hair cell if all mithochondria remove from the cell .​

Answers

Answer:

The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Why do caves form in Sandy Glacier, but not in larger thicker glaciers?

Large, permanent caves like those on the Sandy only form when a glacier is thin and the weight of the ice no longer squeezes the caves shut, allowing warm air to flow into the glacier.

Los métodos hormonales son eficientes porque: * A: impiden la entrada de los espermatozoides C: Se inhibe (no se desarrolla) la ovulación B: El óvulo jamás se encuentra con el espermatozoide D: Los espermatozoides quedan atrapados y no llegan al óvulo

Answers

Answer: C: Se inhibe (no se desarrolla) la ovulación.

Explanation:

Los métodos anticonceptivos se utilizan prevenir el embarazo no deseado, evitando que el esperma fertilice a un óvulo. Hay distintos tipos, los cuales se clasifican en:

Anticonceptivos hormonales: Contienen hormonas, tales como estrógeno y progesterona, que previenen la ovulación (es decir, la liberación de óvulos de los ovarios). De esta manera, al no haber óvulo disponible, por mas que hayan espermatozoides, no va a ocurrir ninguna fecundación. El método mas conocido es la píldora o pastilla anticonceptiva. Anticonceptivos de barrera: Proveen una barrera física que impide la fecundación al impedir el encuentro entre el óvulo y el espermatozoide. Por ejemplo, el uso de preservativos o condones. En estos métodos, se impide la entrada de los espermatozoides, no se encuentran con el óvulo y la esperma queda atrapada dentro del condón. Anticonceptivos permanentes: Proveen un método permanente como  por ejemplo el Dispositivo Intrauterino que se coloca en el tracto uterino con una vida media de meses o años y posee un efecto espermicida que mata a los espermatozoides (por lo que no lograrán encontrar un óvulo). Otro ejemplo es la vasectomía, la cual es una cirugía que corta los conductos deferentes que transportan a los espermatozoides por lo que ya no pueden salir de los testículos para producir la fecundación (quedan atrapados dentro de los testículos, no entran al tracto uterino y no encuentran al óvulo)

Tanto los métodos de barrera como los permanentes, no inhiben la ovulación aunque si impiden que el óvulo se encuentre con el espermatozoide. Entonces, los métodos hormonales son los únicos que logran inhibir la ovulación. Las píldoras que poseen las hormonas previamente mencionadas pero fabricadas sintéticamente. Las mismas mimetizan el efecto de las hormonas naturales producidas por el cuerpo, alterando el ciclo menstrual regular y así evitan el embarazo ya que no habrá óvulo disponible para fecundar. Además, también pueden alterarla mucosidad en el cuello del útero para que los espermatozoides no pueden atravesarlo y llegar al óvulo. De todas maneras, el objetivo principal y mas importante de los métodos hormonales es bloquear la ovulación.

which the cell divides, and what is this phase called?
A. Yellow area: Interphase
B. Yellow area: M phase
C. Blue area: M phase
0 D. Blue area: Interphase

Answers

Answer:

The yellow ares is m-phase

Explanation:

This is where the cell divides into two nucleus.

The blue area in the diagram represents the phase during which the cell divides, and this phase is called the M phase or mitotic phase. Therefore, option C is the correct.

What is mitotic phase?

The mitotic phase, also known as the M phase, is the phase of the cell cycle during which a single cell divides into two identical daughter cells. This process of cell division is essential for growth, development, and repair of tissues in multicellular organisms.

The M phase consists of four stages: prophase, metaphase, anaphase, and telophase. During these stages, the replicated chromosomes condense and align at the metaphase plate, separate and move towards opposite poles of the cell during anaphase, and then decondense and form two separate nuclei during telophase.

The M phase is tightly regulated by a complex network of checkpoint pathways that ensure the accurate segregation of chromosomes and prevent the formation of abnormal cells, which can lead to diseases such as cancer.
