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.
Answer:b

Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.

What are the two parts that describe the measure of force? (your own answer)
Answer:
Force can be measured by the amount of mass in the object and how fast that object is accelerating.
It can also be measured by the change in momentum and the time taken.
When is gravity the strongest? (Select all that apply)
Group of answer choices
When the mass of the object is larger
When closer to the object
When the mass of the object is smaller
When farther away from the obje
Answer:When closer to the object
Explanation:
Answer:
When closer to the object
Explanation:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

What is the relationship between the light-dependent and light-independent reactions of photosynthesis?
Answer:
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

How does the carnivorous plant catch its victums?
Pitfall traps (pitcher plants) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria. Flypaper traps use a sticky mucilage. Snap traps utilise rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum.
Answer:
They use special traps that are connected to them.
Explanation:
For example, the Venus Flytrap uses it's "mouth" to close on the fly. A sundew plant uses sticky spines to stuck to the bugs and slowly curls up and digests the bug.
plz plz plz help The driving force behind the movement of the tectonic plates is..
Group of answer choices
seismic events
drifting due to different densities
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 of these structure types is composed of alternating layers of lava and cinders?
cinder cone
stratovolcano
shield volcano
none of these
The VEI of a volcano’s eruption is based on
the amount of tephra produced.
the height of the eruption cloud.
a descriptive estimate of the explosion.
all of these.
Answer:
1. Cinder cones
2. All of these
Explanation:
1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).
2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.

What does the Greek Root "pro" mean?
Answer:
The prefix pro- primarily means “forward” but can also mean “for.” Some words that the prefix pro- gave rise to are promise, pro, and promote. When you, for instance, make progress, you are stepping “forward,” whereas if you give the pros in an argument, you are speaking “for” something by stating its advantages.

The body temperatures of ectotherms, like lizards and turtles, can fluctuate with the environment. How do ectotherms maintain homeostasis?
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.
