Katen [24]4 years ago

Answer;

-23 in males

In humans, 23 in males is the only homologous chromosome pair that isn't the same.

Explanation;

-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.

Leto [7]

The physical force exerted by a fluid on a structure is HYDROSTATIC PRESSURE . The main pressure is the BLOOD hydrostatic pressure, which pushes materials OUT OF the capillary. The other main force regulating filtration and reabsorption is OSMOTIC PRESSURE , which refers to the "pull" of water into an area by osmosis due to the HIGHER relative concentration of solutes.

Mashutka [201]

The cytoplasm within the cell body is called the<u> perikaryon</u> , although some anatomists use that term to describe the whole cell body.

The nucleus accommodates a prominent<u> nucleolus</u> , where ribosomes are formed.

Free and bound ribosomes are known as Nissl bodies or <u>chromatophilic subtance</u>

Short, small processes that branch off the cell body are <u>Dendrites </u>

The<u> Axon</u> is sometimes called a nerve fiber.

It is typically a longer process emanating from the cell body to make contact with other neurons, muscle cells, or gland cells.

The cytoplasm within an axon is called <u>axoplasm</u>, and the plasma membrane of an axon is called an <u>axolemma</u>.

Explanation:

  • The soma, perikaryon , neurocyton, or cell body is the bulbous, non-process portion of a neuron or other brain cell type, containing the cell nucleus.
  • Perikaryon produce compounds necessary for neuron. Transport compounds to axon and dendrites.
  • The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell
  • Chromatophilic substance is a  prominently staining substance found in the cytoplasm of motor neurons
  • An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma. Axons are in effect the primary transmission lines of the nervous system, and as bundles they help make up nerves.
  • Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function.
  • Axoplasm is the cytoplasm within the axon of a neuron (nerve cell).The axolemma is the cell membrane of an axon.

Sustancia que regula la temperatura del cuerpo, ayuda a llevar nutrientes y oxígeno a las células, convierte los alimentos en en
zavuch27 [327]

Answer:

Agua

Explanation:

El agua costituye aproximadamente 3/4 partes de la tierra, 70% del cuerpo humano esta constituido por agua, y aproximadamente el 90% de las células contiene agua. Esta sustancia es la mas importante para el funcionamiento de nuestro organismo y para alcanzar un equilibrio. Todos los seres vivos dependen del agua para sobrevivir, desempeñando un rol único y central en el funcionamiento de los sistemas vivos.

El agua cumple diversas funciones en el organismo, entre ellas, como las mencionadas en el problema, se encuentra:

  • Regula la temperatura del cuerpo. Dependiendo de la temperatura ambiental, las moleculas de agua permiten que el cuerpo mantenga la temperatura si el ambiente esta frio, y emane calor si la tempeartura ambiental es elevada.
  • Convierte los alimentos en energía. Cumple un rol principal en la descomposición bioquímica de alimentos.
  • Ayuda a llevar nutrientes y oxígeno a las células. Una vez extraidos los nutrientes, se convierte en el medio por el cuál estos últimos pueden transportarse hasta alcanzar las celulas de destino final.
  • Conforma el 83% de la sangre. Como se mencionó previamente consituye la mayor parte de la sangre. Solo el plasma sanguineo esta constituido por el 90% de agua.
