Answer:

Concentration gradients:

Phospholipid bilayer

Membrane proteins

Explanation:

Diffusion: Refers to the pass of some small polar hydrophilic molecules through the lipidic bilayer. There are momentary membrane openings that allow small molecules to freely move from one side to the other in favor of the electrochemical gradient. These openings are the result of the lipids movements. The membrane permeability depends on the size of the molecule. The bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process, and to be efficient requires short distances and pronounced concentration gradients.  

Facilitated diffusion: Occurs when big hydrophilic molecules cannot move freely across the membrane. In these situations, channel proteins are in charge of passive transport. Facilitated diffusion also occurs in favor of electrochemical gradients, meaning that molecules move from the more concentrated side to the less concentrated side.

Simple diffusion and facilitated diffusion are passive transport processes because the cell does not need any energy to make it happen.

Active transport is against the electrochemical gradient, so it does need energy to happen. Molecules move from a lower concentration side to a higher concentration side. This process is always in charge of carrier proteins. In primary active transport, the energy needed comes from the ATP molecule. In secondary active transport, the energy comes from the membrane electric potential.

Transmembrane proteins act in active and passive transport, connecting cells, and participating in signal transduction.    

Channel proteins act by passive transport (these proteins do not need energy to carry in or out substances. They do it according to an electrochemical gradient) and carrier proteins act during active transport (these proteins do need the energy to transport substances because they do it against an electrochemical gradient). These transmembrane proteins carry in those substances needed by the cells to properly perform their activities, and they can also carry out waste substances.

Explanation:

Answer: As these currents flow along the edges of continents, they affect the temperature of the coastal regions. Along the east coast of the U.S., the Gulf Stream carries warm water from the equatorial region to the North Atlantic Ocean, keeping the southeast coast relatively warm.

Explanation:

ATP(adenosine tri-phosphate) stores energy between it's 2nd and 3rd phosphate groups. When the 3rd phosphate group is released ADP(adenosine mono-phosphate) is created and energy is being released. This molecule is important because it stores the energy from cellular respiration and most cellular processes require the energy released by ATP.

Answer:

Reverse carbon dioxide and glucose, and you should be good! In other words:

I hope this helps!

light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

Plants absorb water and carbon dioxide  from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.

Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.

Therefore, light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

Answer:

Strongest is nuclear force while weakest is the gravitational force.

Explanation:

The strongest force is the force of nuclear force while the weakest force is the gravitational force. nuclear force is considered as the strongest force because it binds the fundamental particles i. e. electron, proton and neutron of matter with each other to form larger particles while on the other hand, gravitational force is considered as the weakest force because gravitational force is 1040 times weaker than the electromagnetic force.

Answer:

Strong force and Gravitational force

Answer:

The answer is A nucleus

Explanation:

The process of making mRNA from DNA is called transcription. It occurs in the nucleus. The mRNA moves the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is moved out of the nucleus and into the cytoplasm where it attaches to the ribosomes.

Answer:

increase protection and communal conservancies

Explanation:

increase protection this one is a fairly basic solution, there are many different ways of implementing it. Some park protection agencies in Africa use drones to keep watch at night, while others have sought out military tactics in order to stop black market poachers. Communal conservancies despite global trends, Namibia has done something extraordinary. Between the years of 2002 and 2013, the elephant population has grown from 9,600 to 16,000. The government of Namibia has policies in action where local communities can establish wildlife tourism, and where communities can keep vast amounts of the revenue made.

Answer: FALSE

Explanation:

The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.

Parts of the nervous system includes:

--> Central Nervous System ( consists of the brain and spinal cord)

--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).

The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

[tex]\huge\textbf{Cell Theory}[/tex]

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

It was corrected by the German pathologist  Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

[tex]\huge\textbf{Question:}[/tex]

These observations support the  point that cells could arise only by a division of pre-existing alive cells because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

All these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms, and this explains the cell theory through all these experiments.

Cell theory is a fundamental concept in biology that describes the basic unit of life and its properties, and here in flask 1, if the meat is properly sealed and handled in a sterile environment, it is possible that no microorganisms could enter through it and explain that no growth is seen as no microbes are present. In flask 2, as the meat is open and exposed, it is more likely that microorganisms could be present and potentially grow. Microorganisms are ubiquitous in the environment and can be found in soil, water, air, and on surfaces such as countertops, utensils, and cutting boards. The use of an S tube could potentially reduce the amount of microorganisms that reach the meat due to the curvy path that is present in flask 3.

Hence, all these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms.

Answer:

The environment is not favorable for malarial parasite.

Explanation:

The malaria does not survive well in G6PD deficient cells because the malarial parasite named plasmodium needs blood cells for its survival but in G6PD deficient cells, red blood cells does not perform their function normally which make environment unfavorable for the malarial parasite so that's why we can say that malaria does not survive well in G6PD deficient cells.
