An additional layer of defense and maintains shape
Answer:
Prokaryotes have a cytoplasm, plasma membrane, DNA, and ribosomes, but no nucleus. They have a cell wall that offers an additional layer of protection, prevents dehydration and maintains the shape of the cell. The cell wall is made of peptidoglycan.

Hello may u pls help me with this I'm hella counfused
Explanation:
(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line
(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards
(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move
(4) I think it's both Newton's second law and third law motion.
I hope these helps
Answer:
(1) Is referring to Newton's first law -it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
(2) is referring to Newton's third- law for every action (force) in nature there is an equal and opposite reaction
(3) I think it's also the first law -it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
(4) Newton's second law and third law motion-for every action (force) in nature there is an equal and opposite reaction the acceleration of an object is directly related to the net force and inversely related to its mass

Which best explains why the rate of a reaction decreases at significantly higher temperatures?
A. The activation energy increases.
B. The shape of the enzyme changes.
C. The enzyme-substrate complex forms.
D. The bonds between substrates are broken.
Answer:
B
Explanation:
At significantly higher temperatures, the rate of an enzyme-catalyzed reaction decreases because the shape of the enzyme changes at high temperatures. Enzymes are proteinous in nature, and as such, are generally sensitive to high temperatures.
They simply become denatured by high temperatures. In other words, they lose their original shape and their catalyzing abilities as the temperature gets progressively high during the course of reactions, thus, decreasing the rate of a reaction.
The correct option is, therefore, B.

Answer:
B) hemoglobin comprises for subunits each having one polypeptide chain in one heme group. all hemoglobins carry the same prosthetic heme group iron protoporphyrin IX associated with a polypeptide chain of 141(alpha) and 146 (beta) amino acid residues.
C)sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout the body (hemoglobin).

genetically modified
completely tame
dependent on humans
O exist on an unnatural diet
Obred by humans
found in their natural habitat
Answer:
not adapted to survive in the wild
reared for a purpose
completely tame
dependent on humans
Explanation:
A domesticated animals are not adapted to survive in the wild because they can't survive in that environmental conditions. They are reared by humans for a specific purpose, some animals are reared for meat whereas others are reared for making useful products. These animals are not dangerous or frightened of people and can be domesticated. These animals dependent on humans because they are reared by humans through providing of food to them.

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
Answer:
osmosis
Explanation:
plants use osmosis whic is moving water though a semipermial membrane to draw up water. It moves from places of high conetartions of water (dirt) has to is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.
Plants use osmosis which is moving water though a semipermial membrane to draw up water.
What do you mean by osmosis?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.

Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.
