Answer:
The variety of different genes in a population of organisms
Explanation:
Genetic Diversity is in fact the overall range of individual and varying characteristics in a population. Genetic diversity is what makes different organisms and species unique, and even usher in traits that become favorable for survival. Without genetic diversity, many species would die out before evolving (because it would be near impossible to evolve with their surroundings without genetic diversity).

during photosynthesis where is water split and oxygen released
Answer:
Stroma
Explanation:
Stroma Function. Most of the enzymes essential in the process of photosynthesis are normally embedded in the stroma and in the thylakoid membranes. The stroma is the fluid-filled space that is surrounding the grana, and is also involved in the synthesis of organic molecules from water and carbon dioxide.

why does cell division occur in sexually reproducing organisms?
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.

What would be the speed of a wave with low tension, a distance of 8.5 cm and a time of 3.25 seconds?
The speed of the wave will be 0.026 m/s
The speed of a wave is the distance traveled by a given point on the wave (such as a crest or trough) in a given interval of time.
Speed is given by the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
From the question,
Distance = 8.5 cm
First, convert this to meter
Recall:
100cm = 1m
∴ [tex]8.5 cm = \frac{8.5}{100}[/tex] m
8.5 cm = 0.085m
and
Time = 3.25 seconds
Now, putting the above parameters into the equation
[tex]Speed = \frac{Distance}{Time}[/tex]
∴ [tex]Speed = \frac{0.085}{3.25}[/tex]
Speed = 0.026 m/s
Hence, the speed of the wave will be 0.026 m/s

What are the three kinds of muscle tissues? Where is each located?
Answer:
Cardiac, smooth, and skeletal muscle tissues.
Explanation:
Muscle tissue is classified into three types: cardiac, smooth, and skeletal. Cardiac muscle cells are found in the heart's walls, are striped (striated), and are under involuntary control. Except for the heart, smooth muscle fibers are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are similarly under involuntary control. Skeletal muscle fibers are found in muscles that are connected to the bones. They have a striated look and are controlled voluntarily.
Answer:
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control
Explanation:
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): glucosa 90, trigliceridos 120, hemoglobina,14 y acido urico 6.¿ cual de ellos corresponde a un lipido?
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): El que corresponde a lípidos son los triglicéridos.
Los resultados del estudio de sangre al que fue sometido Carlos son:
glucosa = 90 mg / ml triglicéridos = 120 mg / ml hemoglobina = 14 mg / ml ácido úrico = 6 mg / mlA partir del resultado dado, la opción que corresponde a los lípidos son los triglicéridos.
Los triglicéridos son lípidos (grasas cerosas) que proporcionan energía al cuerpo. Los triglicéridos son producidos por nuestro cuerpo y se obtienen de las comidas que ingerimos. Un triglicérido es un tipo de lípido compuesto por glicerol y tres moléculas de ácidos grasos.
La glucosa tiene la fórmula molecular C6H12O6 y es un azúcar simple. La glucosa es el monosacárido más ubicuo que es un tipo de carbohidrato. La glucosa es producida principalmente por plantas y algas cuando realizan actividad fotosintética a partir del agua y el dióxido de carbono con la ayuda de la luz solar, donde se utiliza para crear celulosa en las paredes celulares.
La hemoglobina es una proteína que se encuentra en los glóbulos rojos (RBC) que transporta oxígeno a los órganos y tejidos y transporta el dióxido de carbono (CO2) de los órganos y tejidos de regreso a los pulmones.
El ácido úrico es un producto de desecho que puede detectarse en la sangre. Se forma cada vez que el cuerpo descompone las purinas. La mayor parte del ácido úrico se disuelve en la sangre, viaja a través de los riñones y se excreta en la orina.
Por tanto, de la explicación anterior, podemos concluir que el resultado que corresponde al lípido son los triglicéridos.
