The Earth's crust is divided into tectonic plates. These plates are located beneath the Earth's crust and are in continuous motion. The plates' movement is caused by the convection currents in the Earth's mantle. The movement of these plates contributes significantly to the formation of landforms on Earth's surface.Mountain ranges like the Himalayans were formed when the continental plates collided.

Tremendous heat and pressure within the Earth cause the hot magma to flow in convection currents beneath the crust. These currents cause the tectonic plates to move, either towards each other or away from each other.In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.

In such regions, magma rises up through the gaps between the plates and cools, forming new crust on the ocean floor. The movement of the tectonic plates contributes significantly to the formation of mid-ocean ridges, volcanic islands, and oceanic trenches.

The three tunics of a blood vessel wall are the tunica intima, tunica media, and tunica externa.

Blood is delivered to human tissues by blood arteries, which act as conduits or channels. Two tube-like closed systems comprised of the vessels start and stop at the heart.

Blood is transported from the right ventricle to the lungs and back to the left atrium by one system, the pulmonary arteries.

The systemic vessels are the other system that transports blood from the left ventricle to the tissues throughout the entire body before returning it to the right atrium. Blood vessels are classified as either arteries, capillaries, or veins depending on their form and function.

Therefore, The three tunics of a blood vessel wall are the tunica intima, tunica media, and tunica externa.

Answer:

When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited. For example:

Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new (de novo) mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

Immediately after karyogamy occurs, the resulting cells are diploid. Karyogamy is the fusion of two haploid nuclei during sexual reproduction, resulting in a diploid nucleus.

Therefore, after karyogamy, the cells will have a diploid nucleus with two sets of chromosomes, one from each parent.

The term "heterokaryotic" refers to a stage in the sexual life cycle of fungi where the cells have two genetically distinct nuclei in the same cytoplasm. "Plasmogamy" is the fusion of two haploid cells' cytoplasm without fusion of their nuclei. Asexual reproduction involves the production of offspring without the involvement of gametes or fertilization, resulting in genetically identical offspring.

In the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.

Auxins are a class of plant hormones that are involved in many aspects of plant growth and development, including phototropism, which is the ability of a plant to bend and grow toward a light source. When a plant is exposed to light from one direction, auxins migrate from the light side of the stem to the shaded side, causing the cells on the shaded side to elongate more rapidly than the cells on the light side. This differential growth results in the bending of the stem toward the light. The concentration of auxins is highest on the shaded side of the stem, where they accumulate due to their movement away from the light. Therefore, in the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.

Beta receptor stimulation on heart muscle decreases force and frequency of contraction through cAMP signaling, increased acetylcholine sensitivity. All responses are correct.

Beta receptor stimulation on heart muscle has a variety of consequences, including a decrease in the force and frequency of cardiac contraction. This is mostly caused by the signaling pathway for cyclic adenosine monophosphate (cAMP) being activated. Increased cAMP levels cause potassium channels to open, which causes hyperpolarization and less calcium influx and, eventually, a decrease in contractile force and a slowing of the heart rate. The cardiac muscle's sensitivity to acetylcholine is also increased when beta receptors are activated, which adds to the overall inhibitory effect. As a result, each of the responses provided accurately describes how beta receptor stimulation affects the heart muscle.

The nervous system can be broadly divided into two major divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

The brain and spinal cord make up the central nervous system (CNS), which is in charge of receiving and processing information from the body and producing reactions. The skull-based brain is where activities like consciousness, feeling, perception, emotion, thinking, memory, and voluntary movement are controlled.

The CNS communicates with the rest of the body through the peripheral nervous system (PNS), which is made up of all the nerves and ganglia outside of the CNS. The somatic nervous system (SNS) and the autonomic nervous system are two more subdivisions of the PNS (ANS).

Two alleles—dominant T for tasting and recessive T for non-tasting—control the trait of phenylthiocarbamide (PTC) taste. PTC taste sensitivity is inherited as a straightforward dominant characteristic. TT, Tt, and tt are tasters, but the others are not.

Alleles and dominant characteristics. Dominant refers to the transmission of characteristics that are often carried vertically from parent to kid and in which the feature or condition caused by that gene affects both the parent and the child.

The most prevalent variety is autosomal dominant, in which the afflicted person carries two alleles of the linked gene, one of which is pathogenic and the other benign, on one of the 22 non-sex chromosomes. In this type of inheritance, the presence of just one harmful allele is enough to confer the characteristic.

The 50% risk of passing on the characteristic to one's progeny is caused by an afflicted person possessing just one of two copies of the pathogenic gene.

Answer: Esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

Explanation:

La fotosíntesis es un proceso utilizado por las plantas y otros organismos fotoautótrofos para convertir la energía de la luz en energía química que, a través de la respiración celular, puede utilizarse para llevar a cabo distintas actividades metabólicas. Esta energía química se almacena en moléculas de carbohidratos, como los azúcares, que se sintetizan a partir de dióxido de carbono y agua. También se libera oxígeno como producto de desecho.

La energía de la luz es absorbida por unas proteínas llamadas centros de reacción que contienen pigmentos verdes de clorofila. En las plantas, estas proteínas se encuentran en el interior de unos orgánulos denominados cloroplastos, que son los más abundantes en las células de las hojas, mientras que en las bacterias están incrustadas en la membrana plasmática. En estas reacciones dependientes de la luz, se utiliza una parte de la energía para despojar de electrones a sustancias adecuadas, como el agua, produciendo gas oxígeno. El hidrógeno liberado por la ruptura del agua se utiliza en la creación de otros dos compuestos que sirven como almacenamiento de energía a corto plazo, permitiendo su transferencia para impulsar otras reacciones: estos compuestos son el nicotinamida adenina dinucleótido fosfato reducido (NADPH) y el adenosín trifosfato (ATP), la "moneda energética" de las células.

El almacenamiento de energía a largo plazo en forma de azúcares se produce mediante una secuencia posterior de reacciones independientes de la luz denominada ciclo de Calvin. En el ciclo de Calvin, el dióxido de carbono atmosférico se incorpora a compuestos de carbono orgánico ya existentes, como la ribulosa bifosfato (RuBP). Utilizando el ATP y el NADPH producidos por las reacciones dependientes de la luz, los compuestos resultantes se reducen y se eliminan para formar más carbohidratos, como la glucosa.  

Entonces, si el carbono en la molécula de dióxido de carbono (CO2) se encuentra marcada radiactivamente, esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

C. Particle size is less important than particle shape for calculating transport speed

Explanation:

brainliest plz

The particles which are smaller in size can diffuse through the cell membrane faster than the particles which are larger in size. Thus, the correct option is A.

Diffusion is the net movement of particles from a region of their high concentration to a region of their lower concentration. This movement takes place through the membrane.

The rate of diffusion depends upon different factors such as nature of particles, size of particles, shape of particles, and the nature of membrane through which diffusion takes place.

Particles which are smaller in size can move faster and diffuse at a high rate than the particles which are bigger in size. The larger size particles cannot diffuse easily hence need proteins such as channel proteins, and carrier proteins for diffusion across the membrane.

Therefore, the correct option is A.
