Answer:
C
Explanation:
The nucleus contains most of the dna and the mitochondria contains a small amount
Mitochondria and nucleus are organelles that are surrounded by two membranes and contain DNA. Therefore, option (C) is correct.
What are cell organelles ?
Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.
Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.
Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

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.

Amino acids form peptide bonds through dehydration. Explain the role of water in this process by describing the chemical reaction.
Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Explanation:
Peptide bonds are- Any reaction that combines two monomers in a reaction that generates H2O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.
Answer:
water is a molecule which will be made

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).

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

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.

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.
