How do adjacent cells that are not directly attached communicate? please explain in detail and explain as much you can please!
Answer:
Cells usually communicate by using chemical signals, these chemical signals which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space.
hopefully this helped sorry if i didn't get to explain more thoroughly.
Help!!! Please Critical Thinking Question:
Why are enzymes specific, and why can't each one speed up many different reactions? Why
this beneficial?
Answer:
The specificity of an enzyme is due to the precise interaction of the substrate with the enzyme. This precision is a result of the intricate three-dimensional structure of the enzyme protein.
Explanation:
Water is a polar molecule because
Answer:
Water is a polar molecule because of its unequal sharing of electrons.
Answer:
The reason why Water is considered a polar molecule is because of Unequal sharing of electrons.
Explanation:
This makes the oxygen end of the molecule slightly negative. Since the electrons are not near the hydrogen end as much, that end is slightly positive. When a covalent bonded molecule has more electrons in one area than another, it is called a polar molecule.

Components in the blood that affect viscosity are formed
elements, plasma proteins, WBCs, RBCs,platelets.What's viscosity provides an explanation for?Viscosity is the resistance of a fluid (liquid or gas) to trade in shape, or motion of neighboring portions relative to each other. Viscosity denotes competition to waft. The reciprocal of the viscosity is called the fluidity, a degree of the benefit of waft. Molasses, for instance, has an extra viscosity than water.
What's an IT unit?Viscosity is a measure of a fluid's resistance to glide. The SI unit of viscosity is poiseiulle (PI). Its different gadgets are newton-2nd per square meter (N s m-2) or pascal-2nd (Pa s.).

what types of organisms would you expect to perform fermentation?
Answer:
Many bacteria and yeasts
Explanation:
Many bacteria and yeasts carry out fermentation. People use these organisms to make yogurt, bread, wine, and biofuels. Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration.

the __________ girdle attaches the upper limb to the axial skeleton.
Answer:
pectoral
Explanation:
Each upper limb is connected to the axial skeleton by the pectoral girdle, which is made up of the clavicle and the scapula.
What is axial skeleton?The clavicles and scapulae make up the pectoral or shoulder girdle. The upper limb bones are joined to the axial skeleton by the shoulder girdle. Additionally, the muscles that move the shoulders and upper limbs join to these bones.
Your upper limbs are attached to the bones along your body's axis by a pectoral girdle, also known as the shoulder girdle. Your body contains two pectoral girdles.
Therefore, the clavicle and collarbone, which together make up your shoulder, make up the pectoral girdle.

what contributes to antigenic shift in influenza viruses?
Answer:
The particular structure of the influenza virus genome and function of its viral proteins enable antigenic drift and antigenic shift.
Answer:
Between worldwide outbreaks, known as pandemics, influenza viruses undergo constant, rapid evolution (a process called antigenic drift ), which is driven by mutations in the genes encoding antigen proteins.
Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains. The term is often applied specifically to influenza, as that is the best-known example, but the process is also known to occur with other viruses, such as visna virus in sheep. Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change.

A student wants to develop an explanation of the role cellular respiration and photosynthesis play in the cycling of matter.
Answering which of the following questions would MOST help the student develop an explanation?
a
Which type of energy is used during photosynthesis and released during cellular respiration?
b
Which products of cellular respiration are also used as inputs during photosynthesis?
c
Which inputs or outputs of photosynthesis and cellular respiration are a source of heat?
d
Which cell organelles carry out the processes of photosynthesis and cellular respiration?
Answer:
D. Which cell organelles carry out the process of photosyinthesis and cellular respiration?
Cellular respiration is the process which occurs in the mitochondria of organisms (plants and animal) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process generate carbon dioxide and water as waste products.
Photosynthesis is defined to as process by which green plants and certain other organisms transform light energy into chemical energy occurs in organelle chloroplast. Thus, the correct option is D which is which cell organelles carry out the processes of photosynthesis and cellular respiration?
What is ATP?
Adenosine 5′-triphosphate, (ATP) is an important “energy molecule” found in all life forms. Mainly, it is a coenzyme which works with enzyme namely ATP triphosphatase to transfer energy to cells by releasing its phosphate groups.
Mitochondria is known as the power house of cell and chloroplast is organelle produce green colour pigment called chloroplast which help in photosynthesis.

explain the effect enzymes have on chemical reactions
Answer:
Enzymes decrease the activation energy, Enzymes increase the rate of the reaction, Enzymes provide a site where reactants can be brought together.
Enzymes are like catalysts which enhance the rate of reaction by lowering the activation energy.
All the biochemical reactions are slow because of transition state barriers. These transition state barriers are an intermediate state before the formation of products. Transition state is a high energy state and it requires a lot of energy to cross this state but we can not produce this much energy in our body. That is why an enzyme is must to catalyze any bio-chemical reaction because enzyme provides an alternate pathway which requires very low energy to proceed.
Enzymes have certain active sites wherein substrates fit in and interact with each other with the help of their functional groups and interaction of these substrates subsequently leads to product formation.
