The diagram below represents the time a cell spends in the two main phases
of the cell cycle. Which section of the diagram represents the phase during
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
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.

wich best describes how mRNA is used by a cell
Explanation:
where are options??????????????
?Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein ...
Answer: Pretty sure its option D that is the correct answer. Transcription of DNA results in the formation of mRNA. A polypeptide chain is formed when codon sequences of DNA reach the ribosome, delivering DNA sequences to the ribosome.

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
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.

explain the absorption of mineral by root hair cell if all mithochondria remove from the cell .
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.
When you have diabetes what is the main body system that is being affected? How does it affect other systems?
Answer:
the main body system is circulatory system?
Answer:
The Circulatory System (Read explanation)
Explanation:
Diabetes affects many of the body's major organs, such as the kidneys, eyes, blood vessels, and heart. Kidney Damage The kidneys filter out your body's waste products. In diabetics, high levels of blood sugar force the kidneys to try to filter large quantities of blood.
It affects other systems because kidneys are technically part of the urinary system and if you have diabetes, it will indeed affect the urinary system. It is all linked together and the domino effect will collapse.

Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?
Answer:
A
Explanation:
All mating must be totally random
Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.
What are the requirements of the law ?In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.
Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.
Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

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
Answer:

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.
