Why is it difficult to fossilize large animals?
There are not enough rocks to cover large animals.
Large animals are harder to cover due to many environmental factors.
Large animals are usually decomposed faster than smaller animals.
Fossilization requires very specific environmental conditions.
Answer:
The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.

B) Hemoglobin is an oxygen-carrying protein found in red blood cells. Describe the structure of hemoglobin.
C) Sickle-cell disease is a genetic disorder that causes red blood cells to become sickle shaped. Explain the cause of sickle-cell disease and the effects of the disorder on patients.
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).

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.

Explanation:
How does blood help maintain the homeostasis in the body?
Answer:
Blood absorbs and distributes heat throughout the body. It helps to maintain homeostasis through the release or conservation of warmth. Blood vessels expand and contract when they react to outside organisms, such as bacteria, and to internal hormone and chemical changes.

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
