The large discrepancies between temperatures due to global warming promote the appearance of hurcanaes, that is, the greenhouse effect and pollution encourage the appearance of excessive thermal amplitude and this helps the appearance of hurricanes.
_______ is the involuntary movement of the muscles that move food through the digestive system.
Answers
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.

What happened when you used a colored filter and a colored lightbulb?
Answers
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.

Answers
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.

The saber-toothed tiger will be clone?
Answers
Answer:First off, they are not tigers. Smilodon and related species are from a group called the Machairodonts, which is a sister group to modern felines.
But yes, Smilodon fatalis is one of about twenty species that geneticists think that they will be able to clone in the not-too-distant future, together with woolly mammoths, dodo birds, moa, and giant ground sloths.
I’m not sure if that’s possible right now, as in July 23 2020, but it is certainly within the realm of possibility, unlike the cloning of Mesozoic dinosaurs.
I would imagine that a mountain lion would be the surrogate mother, as modern pantherines, though closer in size to sabertooths, are far too rare and valuable to experiment on in this way.

Answers
Answer:
c is the correct ans.
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.

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?
Answers
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.

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.
Answers
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.

Trinucleotide repeat is a genetic mutation where a crack of three nucleotides is repeated, next to each other, so many times that it leaves the DNA molecule unstable.
This mutation is capable of causing errors in the reading of DNA, which results in disorders and syndromes in the affected organism.
The three strands of DNA shown above show this mutation.
Support the claim that all living things are made of cells
Answers
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.
The first characteristic of a living thing is that they are made up of cells. A cell is the basic building block of all organisms. It is the smallest unit of organization in a living thing. They contain the organism’s hereditary information (DNA) and can make copies of themselves in a process called mitosis.
Cells are made up of a nucleus and a cytoplasm, enclosed by a thin wall called a membrane, which separates it from its surroundings. Plant cells have a nucleus, cytoplasm, and a cell membrane too. The main difference between a plant and an animal cell is that plant cells have a vacuole, chloroplast, and a cell wall.
