Answer:
both photosynthesis and cellular respiration helps produce oxygen and energy.
Explanation:
photosynthesis is the process of producing food by the leaves of the plants with the help of sunlight.
cellular respiration is the process gaining energy though burning nutrients in the cell.
Thanks! hope it helps : )
Answer:
tres puentes de hidrógeno
Explanation:
El acido desoxirribonucleico (ADN) es una molécula compuesta por dos hélices antiparalelas las cuales interaccionan entre sí a través de puentes de hidrógeno entre bases nitrogenadas. Existen dos clases de bases nitrogenadas: 1-purinas (Guaninas y Adeninas) y 2-pirimidinas (Timina y Citosina). En la doble hélice, la Adenina (A) siempre aparea con Timina (T) a través de dos puentes de hidrógeno, mientras que la Citosina (C) siempre interactúa con Guanina (G) a través de tres puentes de hidrógeno, es decir un enlace de hidrógeno más por cada par de bases. Es por esta razón que una molécula de ADN con alto contenido GC es más estable y por lo tanto tiene una temperatura de desnaturalización mayor.
Monomer
-Carbs : monosaccharide
-Lipids: glycerol & fatty acids
-Protiens: amino acids
-Nucleic Acid: nucleotide
Polymer
-Carbs: polysaccharide
-Lipids: same as monomer
-Proteins: protein/polypeptide chain
-Nucleic Acid: nucleic acid (DNA)
CHONP
-Carbs: CHO
-Lipids: CHO
-Protiens: CHON
-Nucleic Acid: CHONP
Function/Purpose
- Carbs: body's primary source of energy
-Lipids: energy source (long term), cell membranes, hormones
-Protiens: needed for growth and restoration
-Nucleic Acid: Genetic information storage and protein synthesis
Examples
- Carbs: starches, cellulose

- Protein: muscle, hair, nails, enzymes
- Nucleic Acids: DNA, RNA
Low-density lipoprotein is brought into the cell by receptor-mediated endocytosis is referred to as true statement.
<h3>What is Low-density lipoprotein?</h3>
This is also referred to as bad cholesterol because it transports cholesterol in the blood thereby leading to the clogging of the blood vessels and may cause different types of diseases such as high blood pressure etc.
This type of lipoprotein transports all fat molecules around the body in extracellular water and are brought into the cell by receptor-mediated endocytosis which imports the macromolecules from the extracellular fluid thereby making it the correct choice in this context.

Less tilling thanks to genetically modified herbicide-tolerant crops also means that farmers spend less time on their tractors, using less fuel and reducing carbon emissions. Conservation tillage enabled by genetically modified crops has reduced greenhouse gas emissions on farms globally and can help farmers adapt to and mitigate climate change. In fact, in 2014 5.2 billion pounds of atmospheric carbon dioxide emissions were reduced by conservation tillage and decreased fuel use made possible by genetically modified crops. That’s equal to removing nearly 10 million cars from roads for one year.
According to the USDA, adopting conservation tillage can save at least 3.5 gallons of fuel per acre for farmers who would spend less time on their tractors, reducing emissions. If all of the corn planted in the U.S. (non-genetically modified and genetically modified combined) in 2015 was grown with conservation tillage methods, nearly 308 million gallons of fuel would be saved, equivalent to preventing 6.9 billion pounds of carbon emissions.
