Answer:A
Explanation:
Genetic recombination is the rearrangement of DNA sequences by rejoining the chromosome segment. It increases the rate of evolution as it involves the production of germinal cells with increased variability.
What is methods involved in genetic recombination?Genetic recombination can occur in both eukaryotes and prokaryotes. The process of genetic recombination includes the following steps:
Transformation.Transduction.Conjugation.Homologous recombination.Due to recombination in meiosis, different sets of DNA is distributed in each gametes. This produce new combination of genes in zygote.
It also increases the rate of evolution because it involves the production of germinal cells with increased variability.

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.

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.

_______ 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 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.
