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.

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.

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.
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.
In a group of water molecules, hydrogen bonds form between ?
A) two hydrogen atoms in different water molecules
B) the oxygen atoms in different water molecules
C) the oxygen atom in one molecule and the hydrogen atom in another water molecule
D) the hydrogen molecules in a single water molecule
F) Option 3
Pls help will give 14 points for this and brainlist
The correct answer is option c): the oxygen atom in one molecule and the hydrogen atom in another water molecule.
Intermolecular forces or bonds are those interactions that hold molecules together. These are electrostatic forces.
Van der Waals forces are weak attractions that hold electrically neutral molecules together. At some point these molecules present an induced dipole, that is, the molecule acquires a partially positive and a partially negative charge momentarily, causing them to attract each other.
There are Van de Waals forces: Dipole - Dipole Forces, London Forces, Ion - Dipole Forces.
The dipole-dipole forces are forces of attraction between polar molecules. These molecules attract when the positive end of one of them is close to the negative of the other.
Hydrogen bonds are a type of dipole-dipole force. In this interaction, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N).
In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.
Each water molecule has three atoms, two hydrogen and one oxygen.
In this case, between the different water molecules, the hydrogen bond is formed as follows: Oxygen is very electronegative, that is, it attracts the electrons of the bond with much more force than hydrogen.
As a consequence of this, oxygen is negatively charged and hydrogen positively, and a dipole moment is created. In this way, the water molecules clump together with each other.
In summary, the hydrogen in one water molecule is attracted to the oxygen atom in another water molecule.
So, the correct answer is option c): the oxygen atom in one molecule and the hydrogen atom in another water molecule.

https://brainly.com/question/17098636?referrer=searchResultshttps://brainly.com/question/17777036?referrer=searchResultsA 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.

*Please Help* Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation?
A. Invertebrates are more abundant than mammals in an ecosystem.
B. Mammals maintain their body temperature; invertebrates don't.
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
D. Invertebrates have smaller bodies than mammals.
Answer:
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
Explanation:
Net production efficiency (NPE) refers to how efficient an organism at one trophic level utilizes and transfers energy to the next trophic level. Ceetain organisms called CONSUMERS obtain energy by feeding on other organisms. They use this energy for their metabolic activities and transfer the rest when eaten or fed on.
As the trophic level increases, the net production efficiency decreases. This is because organisms at the lower level use energy less than those at higher trophic levels. In this question, invertebrates are mostly PRIMARY CONSUMERS (lower trophic level) while mammals are mostly SECONDARY CONSUMERS (higher trophic level). Therefore, invertebrates use energy more efficiently (less) than mammals, making them have a HIGHER net production efficiency than mammals.

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
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.
