Answer:
Propagación vegetativa
Explanation:
La propagación vegetativa es un tipo de reproducción asexual vegetal a partir de células, tejidos u órganos (por ejemplo, hojas, tallos y raíces) capaces de dar origen a organismos genéticamente idénticos mediante mitosis. Este mecanismo ha sido explotado en mejoramiento genético y en agronomía a fin de reproducir plantas con características fenotípicas deseadas a partir de un número reducido de células somáticas. Las regiones de la planta capaces de dar origen a un nuevo organismos se conocen como propágulos, los cuales pueden ser rizomas (a partir de raíces), tubérculos (tallos), estolones (brote laterales), etc. Diferentes tipos de suculentas tales como, por ejemplo, Sedum morganianum, Sedum rubrotinctum, Kalanchoe daigremontiana y Graptosedum o “California Sunset” se reproducen vegetativamente mediante propágulos foliares.

How might a farmer use artificial selection to increase crop yields over time?
Answer:
artificial selection has a long been used in agriculture to produce animalsand crops with desirable traits. the meatssold today are the results of the selective breeding of chickens, cattle, sheep and pigs. many fruits and vegetables have been improved or even created through artificial selection.
A car turns left while maintaining a speed of 20 m/s. Does the car’s velocity change? Explain your reasoning!
Answer:
Yes
Explanation:
Speed is a scalar quantity (only has a magnitude). It signifies the rate of change of an object's movement.
Velocity is a vector quantity that signifies the rate of change of movement but also the direction of an object's movement.
Since the car turns, its direction changes, so the velocity changes.

What statements are true about the biological macromolecules
-All biomolecules could be called carbon-based molecules.
-The monomers of DNA are nucleotides.
-Ready cellular energy comes in the form of lipids.
-Carbohydrates contain nitrogen and therefore differ from the other macromolecules
-Cell membranes are made, in part, from phospholipids.
-The monomers of starch are monosaccharides.
Answer:
- all biomolecules could be called carbon - based molecules
- The monomers of DNA are nucleotides
- Cell membranes are made, in part, from phospholipids
- The monomers of starch are monosaccharides
Explanation:
Just got that question!
The statements that are true about the biological macromolecule include:
All biomolecules could be called carbon-based molecules. This statement is true concerning biomolecules because all living organisms are made up of the carbon-based molecules which includes:carbohydrates, lipids, proteins, and nucleic acids.The monomers of DNA are nucleotides. This statement is TRUE because Deoxyribonucleic acid (DNA) are polymers which are made up of nucleotide bases.The monomers of starch are monosaccharides. This statement is TRUE because starch is a complex carbohydrate that is made up of long polymers of monosaccharides.Cell membranes are made, in part, from phospholipids. This statement is TRUE because a typical structure a cell membrane contains phospholipids which forms the lipid bilayers that makes it a selective permeable membrane.The biological macromolecules that contains false statements include
Ready cellular energy comes in the form of lipids. This statement is false because cellular energy readily comes from glucoseCarbohydrates contain nitrogen and therefore differ from the other macromolecules. This statement is false because carbohydrates and lipids are made of only carbon, hydrogen, and oxygen but not nitrogen.Learn more here:

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma The part of the neuron that contains the nucleus of the cell and that keeps the cell alive., which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

BRAINLIEST!! Write an essay describing the agricultural/farming practices that contributed to the Dust bowl in in the the 1930s and how it could have been avoided.
The Dust Bowl was a natural disaster that devastated the Midwest in the 1930s. It was the worst drought in North America in 1,000 years.1 Unsustainable farming practices worsened the drought’s effect, killing the crops that kept the soil in place. When winds blew, they raised enormous clouds of dust. It deposited mounds of dirt on everything, even covering houses. Dust suffocated livestock and caused pneumonia in children.
