Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.

movement of the asthenosphere
the Earth's rotation and centrifugal forces
Answer:
Movement of the Asthenosphere
Explanation:
The Asthenosphere is the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur. This convention causes warmer magma in the earth's core to rise and cooler to fall and be heated again. The circular motion caused by this convection is what is thought to cause the Earth's crust to move.

Which level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food?
A. Cell.
B. Tissue.
C. Organ.
D. Organ system.
The level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food in the organ system. The correct option is D.
What is the organ system?An organ system is a collection of organs that cooperate to carry out a certain task in the body of an organism. Organs, which are self-contained collections of tissues like the heart that cooperate to carry out a single function, are present in the majority of animals and plants.
The human body is composed of 11 primary organ systems. These include the reproductive, integumentary, skeletal, muscular, nervous, endocrine, circulatory, lymphatic, respiratory, digestive, and urinary systems.
Organ systems are collections of organs that cooperate to carry out a task for the body they are a part of. They can aid in gas exchange, waste removal, nutrient acquisition and transportation, illness sensing, and disease protection for the body.
Therefore, the correct option is the D. Organ system.

El medio ambiente sufre un constante deterioro por el mal uso que hacemos los seres humanos de los recursos naturales, ¿de qué manera podría intervenir en este tema la BIOTECNOLOGÍA para optimizar esos recursos especialmente desde prácticas empresariales?
Answer:
Nuevas industrias que cuentan con procesos limpios y eficientes.
Explicación:
La biotecnología interviene en la optimización de los recursos naturales mediante la instalación de nuevas industrias que tienen procesos de fabricación más limpios y se utilizan métodos más eficientes al reducir la contaminación química tóxica y las emisiones de gases de efecto invernadero. Debido a estas industrias, se producen pocos daños a nuestro medio ambiente y los productos también se producen para satisfacer nuestras necesidades y requisitos. La biotecnología también reduce las emisiones de CO2 del proceso agrícola y la concentración de pesticidas que se utiliza para producir alimentos.
At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides? A. The number of organelles doubles. B. Chromosomes must be copied. C. Four nuclei must be formed. D. The membrane thickens.
Answer: The correct option is B.
B. Chromosomes must be copied
Explanation:
This is because, before mitosis occurs the cells must first duplicate or replicate it's DNA during interphase and this is because mitosis is a type of cell division where a parent cell divide into two daughter cells which are genetically identical to the parent cell and carry the exact number of chromosomes of the parent cell.

A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.
Answer:
B
Explanation:
Cause I say so
The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.
What is Population?A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.
According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.
Therefore, the correct option for this question is A.
