Give advantages of endothermic animals

Answers

Answer:

The advantages of endothermy are well known: the ability to occupy thermal niches that exclude many ectothermic vertebrates, a high degree of thermal independence from environmental temperature, high muscular power output and sustained levels of activity, to name but a few.

The major advantage of endothermy over ectothermy is decreased vulnerability to fluctuations in external temperature. Regardless of location (and hence external temperature), endothermy maintains a constant core temperature for optimum enzyme activity.

Question 6
What would an ecologist use latitude to describe?
O A) the average weather conditions of a specific location
OB) the distance of a point from Earth's prime meridian
O C) the distance of a point from the Earth's equator
D) the distance of a point from the Earth's north pole
Next Question
what would and ecologist use latitude to describe?

Answers

Answer:

c the point of distance from the earths equator

Explanation:

Latitude measures equator distance. Latitude lines travel east-west parallel to the equator from 0 degrees latitude.Therefore, option (C) is correct.

What is a latitude?

Latitude is a type of coordinate that indicates the position of a place on the surface of the Earth or another celestial body in relation to the north and south poles. When expressed as an angle, latitude can run anywhere from –90 degrees at the south pole to 90 degrees at the north pole, with 0 degrees denoting the equator.

The equator, located at 0 degrees, the Tropic of Capricorn, located at 23.5 degrees south, the Tropic of Cancer, located at 23.5 degrees north, the Antarctic Circle, located at 66.5 degrees south, the Arctic Circle, located at 66.5 degrees north, the South Pole, located at 90 degrees south, and the North Pole, located at 90 degrees north are the seven significant lines of latitude.

Where must an mRNA attach before protein production can begin?

Answers

Answer:

to a Ribosome

Explanation:

mRNA is produced inside the nucleus of a cell according to the genetic information present in the DNA of the cell. this process is known as Transcription.

Then it's sent to ribosomal subunits in the cytosol through nucleopores. then it attaches to the ribosome. the ribosome reads the nitrogenous base sequence and pairs the tRNAs with complementary nitrogenous bases. (your answer is here, but if you want to know more, continue reading it.)

Each tRNA contains a tri-nucleotide that is collectively known as an anticodon which has the complementary bases of the relevant codon on the mRNA.

Each tRNA has captured a protein. the type of protein is determined by the sequence of the anticodon.

It means two tRNAs with two different anticodons cannot bring the same protein to the ribosome.

the Ribosome separates the proteins attached to tRNAs and links them as a chain.

the final result is a polypeptide chain. I explained to you the basic protein synthetic process.

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax

Answers

The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in,  the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

The blood protein hemoglobin that helps carry oxygen throughout the body and carbon dioxide to your lungs. High hemoglobin levels can cause dizziness, fatigue, easy bruising, and other symptoms.

What are the three kinds of muscle tissues? Where is each located? ​

Answers

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.

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?

Answers

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 / ml

A 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.
