Answer:
I believe D. Light
Explanation:
Well, light is the main source of food for plants along with the addition of carbon dioxide.
Answer:
a) food
Explanation:
IT is because animals and plants dont need darkness cause it is of no use to them. locomotion is only there in animals so it wont benefit both. and for light animals dont need it while plants do. so the only option that benefits both is option a food.

qual é o resultado da meiose ?
Answer:
El proceso da como resultado cuatro células hijas que son haploides, lo que significa que contienen la mitad del número de cromosomas de la célula madre diploide. La meiosis tiene similitudes y diferencias con la mitosis, que es un proceso de división celular en el que una célula madre produce dos células hijas idénticas. Espanol
English: The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

[tex] \huge \mathfrak{{ \pmb{ \underline{ \red{Answer}}}}}[/tex]
The red blood cells and brain are two body tissues that derive most of their energy from glucose.
Glucose is the answer.
The red blood cells and brain are two body tissues that derive most of their energy from carbohydrates. The correct option is C.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
Under normal conditions, glucose serves as the brain's main energy source.
Using either glycolysis or oxidative phosphorylation—the latter of which is 15 times more efficient—glucose is used to create energy in the form of adenosine triphosphate (ATP).
In the absence of glucose, the brain has backup energy sources, such as ketones created by fatty acid metabolism, which predominantly takes place in the liver.
These include 3-hydroxybutyrate, acetone, and acetoacetate (3BHM).
Thus, the correct option is C.

What role do the macromolecules starch and simple sugars play in fruit storage and ripening?
The role that is played by macromolecules such as starch and simple sugars in fruit storage and ripening is that the unripe bananas store starch in their chlorophyll.
Macromolecules refer to very large molecules. The four main classes of macromolecules include lipids, proteins, nucleic acid, and carbohydrates.
It should be noted that starch is stored in the chlorophyll content of the peel of the unripe bananas. During ripening, there'll be an increase in the breakdown of the starch that can be found in the fruit and this will ensure there's an increase in the glucose too.

Newly synthesized proteins destined to be secreted from the cell are likely to be found in all of the following places EXCEPT:
The lumen of the ER
The lumen of the Golgi
The lumen of the lysosome
The lumen of the SER
Moving to the next question prevents changes to this answer.
Newly synthesized proteins destined to be secreted from the cell are likely to be found in all the options except the lysosome.
Both the endoplasmic reticulum and Golgi apparatus are involved in protein processing and transport.
However, the lysosome is an organelle responsible for digesting or degrading excreted biomolecules as well as dead organelles. The lysosome is spherical and most contain digestive enzymes capable of degrading biomolecules in its lumen. Thus, a protein destined to be secreted from the cell will most likely not be found in the lysosome, otherwise, the protease enzyme present in its lumen would degrade them.

Answer:
Covalent bond
Explanation:
The answer is covalent bond
A molecule of octane which is a component of gasoline contains covalent bonds.
Octane is a hydrocarbon compound, specifically an alkane, with the molecular formula C8H18. The structure you've provided illustrates the arrangement of carbon (C) and hydrogen (H) atoms in octane.
In octane, each carbon atom forms four single covalent bonds with other atoms (either carbon or hydrogen). Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration. In the case of octane, carbon atoms share electrons with other carbon and hydrogen atoms to fill their valence electron shells, resulting in a stable and energetically favorable arrangement.
The structure of octane is a straight-chain alkane, with carbon atoms forming a chain and hydrogen atoms attached to the carbon atoms. The single covalent bonds between the atoms are represented by lines in the structural formula.
The shape of the molecule is determined by the arrangement of atoms and the types of bonds between them. In the case of octane, the single covalent bonds allow the carbon atoms to form a linear chain.
In conclusion, octane molecules are held together by covalent bonds, specifically single covalent bonds between carbon and hydrogen atoms. This type of bonding contributes to the stability and structure of the octane molecule, making it a major component of gasoline and contributing to its combustible properties.

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
As to the digestive tract, the function of the lipases would take place in the small intestine.
Lipase is an enzyme that helps us to metabolize fat. It does this through hydrolysis. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.
Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.
Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.

https://brainly.com/question/2847647?referrer=searchResults
In the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.
Fat digestion occurs efficiently and almost completely in the small intestine by pancreatic secretion of lipases.
Pancreatic lipase acts on triacylglycerides to give free fatty acids and monoacylglycerides.
First, they are absorbed by the epithelial cells of the intestinal wall called enterocytes, creating complex particles called chylomicrons, loaded with triglycerides.
Fatty acids are re-esterified within the enterocyte and enter circulation through the lymphatic pathway as chylomicrons.
Chylomicrons bind to lymph, which carries them to the bloodstream, this indicates the great importance of lymph in the process of assimilation of dietary fats.
Therefore, we can conclude that in the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.
