Answer:
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients.

how many calories are in an average trick-or-treaters halloween stash?
The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.
Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.
Considering this, in a Halloween stash the calories depend on two factors:
The types of candies or productsThe units of each oneLet's suppose there are 5 units of each of the following candies:
Chocolate barsTaffiesLollypopsCandy cornLet's now calculate the calories
Chocolate bars = 220 calories x 5 units = 1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 caloriesAdd all the previous results:
1,100 + 100 + 415 + 35 = 1,650 calories in total

Briefly explain the evolution of oxygen on earth.
Answer:
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. ... "What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago.
Explanation:
Which molecule supplies chlorophyll with electrons
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.
▪▪▪Cutest Ghost▪▪▪Water is the molecule that supplies chlorophyll with electrons.
What happens during photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.
During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.

CELL DIFFERENTIATION:
Cell differentiation is the process by which an unspecialized cell becomes specialized in function. Cell differentiation is undergone by stem cells, which are regarded as totipotent cells. The process of cell differentiation occurs as a result gene expression. Cells like heart cells, blood cells, liver cells, kidney cells etc. are examples of specialized cells.

Low precision and low accuracy best describe the archer's results. So the correct option is A.
Who is an archer?Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.
With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.
Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.
Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.
During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.
Therefore the correct option is A.

What are centrioles and centrosome?
Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm
Explanation:
Answer:
a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.
Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

nucleic acids are assembled in the _____ direction.
Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.
What are Nucleic acids?Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.
