Answer:
second)some of the energy disperses as heat
Explanation:
This second law of thermodynamics states that in the course of conversion of energy from one form to another in an organisms,this can not be 100% efficient ( there is constant increase in entropy of the systems in the organism)as some of the energy is dissipated as heat in the course of conversion.
Thus in a food chain as energy is been converted from one trophic level( primary consumer) to another( secondary consumer) these organism makes use of the energy to do biologic work.Therefore as this is passed to other organism in the tropic levels not all the initial energy will be available ,as some has been lost during biology work,respiration , excretion ,movements and locomotion. in the subsequent organisms.
Thus the entropy of the organisms involved increases as energy is been transmitted from one trophic level to another which leads to heat dispassion.

A hypothesis is a ___.
Answer:
A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.
Explanation:
In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.
So, we can conclude that The hypothesis is a simple statement that defines what you think the outcome of your experiment will be.

A neuromuscular junction is a junction between a_________ and a ___________. A neuromuscular junction is a junction between a_________ and a ___________. dendrite of an axon; skeletal muscle fiber bulbous end of axon; skeletal muscle fiber sarcoplasm; T-tubule dendrite of an axon; myofibril bulbous end of axon; cell body of axon
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.

What happened when you used a colored filter and a colored lightbulb?
Answer:
A filter is a transparent material that absorbs some colors and allows others to pass through. ... A yellow color filter will let through only yellow and absorb all other colors. So when blue light is allowed through a blue filter onto a blue object, the object will still reflect blue and therefore appear blue.
Answer:
The person in the simulation could see the colored light only if it passed through a filter of the same color. This filtering of color occurred because the filter absorbs the other colors. The filter lets light that’s the same color as the filter pass through, allowing the person to see that color.

it transmits information between different parts of nervous system.
Answer:
C. It transmits information between different parts of the nervous system.
Explanation:
The nervous system has two parts, the central nervous system and the peripheral nervous system.
The central nervous system includes the brain, and the peripheral nervous system includes the spinal cord.
The spinal cord is a long, thin, tubular structure that consists of nervous tissue. The spinal cord extends between medulla oblongata in the brain to the lumbar region. It is protected by the spinal column made up of bones, called vertebrae.
One function of the spinal cord is to receive and transmit signals to the entire body and back to the brain.
The spinal cord recieves nerve impulses from the body and transmits it to the brain. It also receives orders in form of nerve impulses which are transported to receptors for response.

Explanation:
Kala added a spoon of yeast and hot boiling water to knead bread dough, whereas Rupa added warm water to knead the dough with yeast in it. Both of them made bread. Whose bread will be soft? Why?
Answer:
I think Rupa's bread will come out softer than Kala's.
Explanation:
Using hot boiling water to activate yeast can kill it. Instead of being absorbed by the protein, the hot water is absorbed into the starch molecules.
It is better to use warm water to get a more fluffy bread.
Soft bread is soft because CO2 produced by yeast and water that gets turned to steam by the baking process gets trapped into pockets by a mesh of gluten, causing the dough to expand. The dough then solidifies, keeping its shape. If your bread is not soft then it hasn't expanded enough for one or more reasons.

_______ is the involuntary movement of the muscles that move food through the digestive system.
Answer:peristalsis
Explanation:
a wave like motion that occurs in the stomach to move food down
Peristalsis is the involuntary movement of the muscles that move food through the digestive system. The correct answer is peristalsis.
What is Peristalsis?
It is a coordinated, involuntary muscular movement that occurs in the walls of the digestive tract, specifically the esophagus, stomach, small intestine, and large intestine. It plays a crucial role in propelling food and liquids through the digestive system, allowing for the efficient processing and absorption of nutrients.The process of peristalsis begins when food is swallowed and enters the esophagus. The walls of the esophagus contain smooth muscle tissue that contracts and relaxes in a wave-like pattern. This contraction is initiated by the swallowing reflex, which is triggered by the act of swallowing.Peristaltic contractions in the small intestine help to propel the chyme along its length, allowing the absorption of nutrients from the intestinal walls.The rhythmic contractions help to move the waste material, also known as feces, toward the rectum.
Therefore, the answer is peristalsis.

A wolf kills a deer that is infected with ________ of Echinococcus granulosis in its liver and eats it. After consuming the deer, the wolf's intestine becomes filled with a number of ________ produced from scoleces. These eventually release eggs into the wolf's intestines, which are released in its feces.
Answer:
The deer is infected with the parasite taenia Echinococcus granulosis, which is in the development stage of the fertile hydatid cyst. The wolf's intestine becomes filled with adult parasites, that eventually release eggs from their proglottids.Explanation: Echinococcus granulosis biological cycle.
The adult form of the parasite Echinococcus granulosis inhabits the intestines of canids, such as the dog or in the wolves, as in the exposed example. They might be 2 to 7 millimeters long, and in their anterior extreme, there is a segment known as scolex or head. The invertebrate attaches to the intestine wall by using its scolex. In the posterior extreme, there are the fertile segments of the animal, formed by three or four proglottids. The proglottides, carry the eggs and release them in the canid´s intestine. These eggs can get out of the animal´s body when it defecates. The parasite´s eggs are now in the feces of the canid.
Once on the ground or in the water, these eggs might be ingested by an intermediate host. In general, these hosts are animals such as sheep, goats, horses, pigs, and even humans. In the exposed example, the intermediate host is the deer.
The eclosion of the parasite´s eggs occurs in the thin intestine of their host, during digestion. The invertebrate penetrates the intestinal wall, from where it migrates to other organs, especially the liver and the lungs. At this point, the organism known as the oncosphere, turn into hydatid cysts. In its interior, it starts the protoscolex formation, making the size of the cyst to get bigger. When the protoscolex is completely formed, the fertile cyst is now infectious to the final host.
The final host (wolves) becomes infected when it feeds on the intermediate host. After ingestion, protoscolex gets released in the interior of the duodene. Their free state is known as scolex. At a certain point, scolex gets attached to the intestine wall where they stay until they become adults. And the cycle starts again.

A mother has blood type A and her son has blood type 0. Which blood types are possible for the father?
o AB
оо
ОА
о в
Answer:
Blood types O, A, and B are possible for the father.
Explanation:
Since the mother has type A blood, there are two possible genotypes that she can have: AA or AO. Since her son has type O blood, he only has one genotype: OO.
For blood types,
Type A - AA or AO
Type AB - AB
Type B - BB or BO
Type O - OO
* A and B are dominant over O.
Now we have to do crosses between the mother and the father:
AA mother with AB father: child with type AA or type AB blood
AO mother with AB father: child with type AA, AO, AB, or BO blood
AA mother with OO father: child with AO blood
AO mother with OO father: child with AO or OO blood
AA mother with AA father: child with type AA blood
AA mother with AO father: child with type AA or AO blood
AO mother with AA father: child with type AA or AO blood
AO mother with AO father: child with type AA, AO, or OO blood
AA mother with BB father: child with type AB blood
AA mother with BO father: child with AB or AO blood
AO mother with BB father: child with AB or BO blood
AO mother with BO father: child with AB, AO, BO, or OO blood
The father can have blood types O, A, or B.

Which of the following describes the structure of an amino acid? A. Small molecules consisting of a phosphate group, a sugar, and a nucleotide base B. A long chain of carbon atoms connected to oxygen and hydrogen atoms C. A long chain of protein molecules D. Small molecules consisting of an amino group, a carboxyl group, and a side chain
Answer:
i think option d is the answer.
The small molecules consisting of an amino group, a carboxyl group, and a side chain describes the structure of an amino acid.
What are the functions of amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, from which proteins are composed.
Amino acids function as the building blocks of proteins. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues.
Amino acids connect to form peptide bonds through a reaction between the amino group and the carboxyl group. The amino functional group is therefore critical to building all the proteins that makeup life on earth.
