Answer:
Osmosis
Explanation:
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
This direction is from high concentration to low concentration, this will create equilibrium.

A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?
Answer:
Cellular respiration
Explanation:
Herbivores are organisms that feed on plant materials solely. They are usually animals like sheep, cattle, goats with four stomach compartments. They are part of the global carbon cycle which shows how carbon is circulated in nature.
Plant matter is broken down by herbivores through a series of metabolic steps. The final product is a glucose laden material which is the raw material needed for cellular respiration. When oxygen combines with the glucose, energy is liberated, and carbon dioxide, a waste product is released into the atmosphere. This way, carbon is cycled in the ecosystem.Answer:
Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.

The moon's mass is about 1.2% of the mass of the earth.Answer:
The moon is about one-fourth the size of Earth.Explanation:
Being the moon of the earth, it is only natural that the moon is 1/4 of the size.
What do all forms of active transport have in common?
Answer:
-Using ATP
Explanation:
Cells use various mechanisms to move substances across their plasma membranes. Plasma membranes are selectively-permeable and capable of controlling all movement of substances through:
passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.Active transport involves the movement of substances out of cells against their gradients. For instance, glucose is transported across the membrane with specialized carrier proteins embedded within the membrane, and active transport; the cell's interior is highly concentrated- glucose is a high energy storage molecule required by many metabolic processes and required in high amounts.
The forms of active transport that should be in common is by using the ATP.
Forms of active transport:The plasma membrane should be selected also capable for controlling the movement of the substance via the passive transport where it does not use the energy and the active transport means when it needs the chemical energy in the form of ATP.
The interior of the cells should be highly concentrated glucose that shows an high energy storage molecule.

Explanation:
The energy that is released during cellular respiration is stored in molecules of what :
a. NADPH
b. ATP
c. Nucleus
d. None of the above
Answer:
b. ATP
Explanation:
Cellular respiration begins in the cells' cytoplasm, where glucose is broken down for energy processing. The process continues in the mitochondria, where energy is produced by aerobic respiration in the presence of oxygen.
Cells break down energy-rich bonds in sugars in the form of glucose to produce carbon dioxide and (water) during aerobic respiration in mitochondria to receive energy in the form of ATP or adenosine triphosphate.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
(33) Energy released when organic compounds break down is measured in what unit?
(A) mg/sec (B) ug (c) Calories (0) °Clg
Answer:
Calories
Explanation:
It is called calories because calories is the unit of measuring energy gotten from the consumption of food or drink when it is breakdown.
During digestion, when the bonds binding food are broken down, energy is released . This energy is used for metabolic activities of the body and the energy released is measured in units called kilocalories or calories

Which idea did Lamarck propose that was rejected by his fellow scientists?
can i have brainest? please? anways hope i helped
Answer:
The correct answer will be acquired traits can be passed to offspring.
Explanation:
Lamarck is known for his idea of "inheritance of acquired traits" by studying neck size of giraffes and stated that:
1. New organs or traits can be produced by long use during lifetime as response to external environment,
2. characteristic is inherited to the next or succeeding generations.
3. Organ can disappear if not used.
Scientists were not able to find and explain evidence for the theory for example :
1. The blacksmith’s arm- enlarges when used continuously against external resistance like weight of the hammer but it is not necessary that the smith’s children at birth would have large arms or later in his life.
2. Skilled Hands of a musician- skillful hands of a musician causes no increase in the size of the fingers and this trait might be passed to musician’s children and they also play instrument skillfully with no practice.
Thus, acquired traits can be passed to offspring is the correct answer.
What can be said about the DNA analysis of closely related organisms.
Answer:
Now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
Cellular respiration continues in the mitochondria of the cell with the _____________ cycle and the electron transport chain
Answer:
Cellular respiration continues in the mitochondria of the cell with the Krebs cycle and the electron transport chain.
Explanation:
The Krebs cycle is an important part of the cellular respiration process where —from energetic substrate such as carbohydrates, lipids and eventually proteins— Acetyl-CoA is obtained, whose oxidation produces energy in the form of ATP.
Both cellular respiration and Krebs cycle reactions occur in the mitochondria of the cells of aerobic organisms and, in conjunction with the electron transport chain, have a yield of 24 molecules of ATP for every molecule of glucose entering the system.

Most fish can see very well and some fish even have a special eye structure called the Tapetum lucidum that allows them to see very small amounts of light. How does this structure work?(look under sharks for answer)
Answer & Explanation:
Vision is simply the sense or ability of sight; the ability to see or the perception of light. Tapetum lucidum present in most fishes especially the nocturnal ones and sharks, is located behind the retina. It is a special eye structure whose function of which is to return rays of light that have escaped from the retina back to the retina to improve vision. This has enabled them to survive in an environment where light readily disappears due to depth.

Question 1: What motor protein is associated with actin?
Question 2: What is the microtubule organizing center of most eukaryotic cells?
Question 3: Which diseases cause an effect on the cytoskeleton of cells? Do you think a cell can function without a cytoskeleton?
1.This type of enzyme, which converts chemical energy into mechanical energy, is called a mechanochemical enzyme or, colloquially, a motor protein. Myosin is the motor, actin filaments are the tracks along which myosin moves, and ATP is the fuel that powers movement.
2.The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
3.Cytoskeletal protein aberrations are the underlying reason for many pathological phenotypes. It is no surprise that modifications in such a crucial cellular structure lead to pathological conditions. Indeed, many diseases have now been associated with abnormalities in cytoskeletal and nucleoskeletal proteins, including several cardiovascular disease syndromes, neurodegeneration, cancer (invasion), liver cirrhosis, pulmonary fibrosis, and blistering skin diseases. The mechanisms by which many micro‐organisms infect specific cells have been shown to depend on host cytoskeletal elements. Attempts to modulate the cytoskeleton by peptides or other specific drugs have already yielded interesting results and this will lead to new therapeutic agents in the foreseeable future. The impact on cancer treatment is a convincing example: anti‐cytoskeletal (microtubule targeted) drugs are already used to inhibit cell division.
