According to the kinetic theory of matter, how many particles that make up a substance are constantly in motion?
Answer:
D
Explanation:
According to the kinetic theory of matter, option D. all the particles that make up a substance are constantly in motion.
The Kinetic Theory of Matter states that all matter is made of particles that are atoms and molecules that are constantly in motion in the substance, therefore, particles of all matter have kinetic energy.
Some particles have more kinetic energy than other particles due to fact that all particles of matter do not move at the same speed even though particles of matter are constantly moving.The temperature of matter or object is the average kinetic energy of the particles in an object.Thus, the correct answer is - option D. all the particles.

Neurons are constantly firing on a regular basis in order to keep your body functioning. In your words, describe how a neuron utilizes a stimulus to create an action potential. (Be detailed)
Answer:
Neurons are in charge of receiving stimuli from the environment, transforming them into nervous excitations and transmitting them to the nerve centers, where they organize themselves to give a response.The cycle of depolarization and hyperpolarization of the membrane and return to the resting membrane potential is called the action potential, an all-or-nothing reaction that can occur at rates of up to 1,000 pulses / second. Membrane depolarization that occurs as voltage gate Na + channels open at one point on an axon passively spreads a short distance and triggers the opening of adjacent channels, resulting in the generation of another action potential. In this way the depolarization wave, or nerve impulse, is conducted along the axon.
Explanation:
Neurons are highly specialized cells whose central function consists in the generation and transmission of signals, in order to communicate with the other neurons of the nervous system and with the outside of the organism. They are made up of three parts: the cell body, the dendrites, and the axon. Dendrites are extensions of the cell body with short, tubular branches, through which each neuron receives signals from other neurons. These signals are added or averaged, and in the event that the total intensity of the received stimulus is greater than a certain threshold, the neuron will generate and emit an electrical response signal. This signal will be sent through the axon, which will transmit the information to other neurons through chemical exchange. The axon divides near the end into thin branches that contact other neurons. The point of contact is called the synapse. At the synapse, there is a gap between the two cells called the synaptic cleft. The synapse is produced by the release of chemicals from the presynaptic neuron that excites the postsynaptic, transmitting the informational code. The arrival of an impulse at the end of a nerve fiber causes a chemical compound, a transmitter substance, to be released, which excites the neighboring neuron. The same neuron may have inhibitory and excitatory connections with different neurons, for which it will need to produce different chemicals that act as transmitters. A neuron receives and integrates multiple stimulations through the synapses, those received by the dendrites are added to those received in the soma so that the electrical potential of the cell membrane ends up exceeding the threshold and originates a nerve impulse in the area of the axonal cone. Nerve impulses are electrical signals generated by the spike trigger sites (axon cones) of a neuron as a result of membrane depolarization, which are conducted along the axon to its termination. The transmission of impulses from the endings of a neuron to another neuron, a muscle cell or a gland occurs at the level of the synapses.
What is the end result of DNA replication?
O An mRNA strand that will be used to create a protein.
O two strands of DNA that are identical to cach other
O An MRNA strand that will not be used to create a proteir
O Two strands of DNA that are different from one another.
Answer:
two strands of DNA that are identical to each other
Explanation:
Replication is defined as the process in which two identical copies of DNA is formed from parent DNA strand. The end result of DNA replication is two strands of DNA that are identical to each other which are called chromatids. The process of DNA replication is known as semi-conservative as the end result is consist of one new and one old chain of nucleotides.
Hence, the correct answer is "two strands of DNA that are identical to each other".

What factor prevents us from finding fossils from the Precambrian era?
A. Life-forms in this era had no skeletons.
B. This was before life existed on Earth.
C. Life was destroyed by a series of mass extinctions.
D. There are no rocks left from that era.
Answer:
rhe answer is that the rocks of that time are buried deeply under the soil.
The factor that prevents us from finding fossils from the Precambrian era is that life-forms in this era had no skeletons. Therefore, option (A) is correct.
What was Precambrian era?The Precambrian era spans from the formation of Earth about 4.6 billion years ago to the start of the Cambrian period about 541 million years ago. During this time, life on Earth consisted mainly of simple, single-celled organisms such as bacteria and algae.
These organisms lacked the hard shells, bones, and other structures that are typically preserved as fossils. Therefore, the fossil record from the Precambrian era is relatively sparse, consisting mainly of impressions and other traces left by these early organisms in sedimentary rocks.

choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

Give two examples of phospholipid soluble molecules? How can these molecules move across the cell membrane? What affects the direction of their movement
Answer:
1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
Explanation:
Hope this helps. ^_^
Answer:
Examples include steroids and Vitamins
Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.
Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .
These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.
The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.
