The mechanism by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as Photosynthesis.

Green plants and various other organisms convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change waters, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

The significance of photosynthesis Solar or radiant energy is converted into chemical energy during photosynthesis. The production of agricultural crops is directly impacted by the rate of photosynthesis. All living things require oxygen, which it provides for the atmosphere. It keeps the ecosystem's carbon dioxide and oxygen levels in check.

Answer Options:

a. glycogen + fructose = maltose

b. galactose + glucose = lactose

c. glucose + sucrose = fructose

d. maltose + lactose = cellulose

Answer:

b. galactose + glucose = lactose

Explanation:

Monosaccharides are single units. Disaccharides are molecules of two monosaccharides joined together.

Examples of monosaccharides include glucose, fructose, and galactose.

Examples of disaccharides include lactose, maltose, and sucrose.

The only example that shows this is b.

Answer: Although humans cannot prevent all cancers, a healthy diet and weight followed by adequate exercise, sleep, and stress reduction all play a part in cancer reduction.

Cancer occurs when cells multiply uncontrollably and are not "cleaned up" by the body. We are dependent on our bodies recognizing and destroying old cells and foreign substances like toxins. When our body's fail to do this, either through stress, poor diet or being sedentary, cancer could result.

Answer:

The King Cobra and the Black Mamba

EXPLANATION:

The black mamba is a species of highly venomous snake belonging to the family Elapidae. It is native to parts of sub-Saharan Africa. First formally described by Albert Günther in 1864, it is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 m and commonly grow to 3 m

The king cobra, also known as the hamadryad, is a venomous snake species in the family Elapidae, endemic to forests from India through Southeast Asia. It is threatened by habitat destruction and has been listed as Vulnerable on the IUCN Red List since 2010. It is the world's longest venomous snake.

Answer:

The two types of venomous snakes are Elapine snakes, and Viperine snakes. Elapine snakes have shorter fangs and venom that paralyzes the respiratory system. Cobras and coral snakes are Elapine snakes. Viperine snakes have longer hollow fangs and venom that attacks red blood cells. Rattlesnakes are viperine snakes.

Independent variable: different amounts of second-hand smoke

Explanation:

The independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.

In this question, a test is being carried out to determine the health effects of different amounts of second-hand smoke on one-year-old hamsters. Based on this, the independent/manipulated variable is the DIFFERENT AMOUNTS OF SECOND-HAND SMOKE because it is the variable being changed.

Answer:c salt ions move out of the cell

Explanation:

Salt is less than 1

Red blood cells have a salt content of 0.9%. When a microbiologist places red blood cells in pure water, osmosis occurs. This results into water molecules . Thus, the correct option is C.

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential or lower solute concentration to a region of low water potential or higher solute concentration, in the direction which tends to equalize the solute concentrations on the two sides of the membrane.

It is of two types, on the basis of movement of solvent particles, when the solvent moves inside the cell it is called endosmosis which results into turgid cells and the movement of solvent molecules outside the cell which is called exosmosis that results into flaccid cells.

Therefore, the correct option is C.

Answer:

B. Trace Evidence

Explanation:

Trace evidence is like fiber or hair or gunshot residue to it would be B. Trace evidence

The physical evidence and trace evidence are both reviewed under microscopy. Therefore, option A and option B are correct statements.

Microscopy is a technique to review the smaller size object at high magnification. Forensic science uses the physical or trace evidence found at the crime scene to review under microscopy.

Physical evidence refers to the tangible objects found at the crime scene, such as murder weapons or tool marks. On the other hand, trace evidence refers to the small or even microscopic pieces of evidence left at the crime scene, such as hair, or DNA.

Using the microscopy technique, the forensic team can determine the source of the murder weapon used at the crime scene or even link the suspect to the death of the victim. However, other types of evidence that do not come under microscopy, such as testimonial evidence or circumstantial evidence are also used to build a strong case against the suspect.

Therefore, the physical evidence and the trace evidence both are reviewed under microscopy.

Answer:

Independent variable: MUSIC

Dependent variable: PULSE

Control group: The 5 volunteers that did not listen to music.

Experimental group: The 5 volunteers that listened to seven different music selections for 30 seconds each

Explanation:

- Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment, the independent variable is DIFFERENT TYPES OF MUSIC THAT WAS PLAYED BY CARIE.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable being measured in an experiment. The PULSE, which was measured in this experiment, is the DEPENDENT VARIABLE.

- Control group is the group of an experiment that does not receive the experimental treatment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT DID NOT LISTEN TO ANY MUSIC is the CONTROL GROUP.

- Experimental group is the group that is subjected to the experimental treatment in an experiment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT LISTENED TO SEVEN DIFFERENT TYPES OF MUSIC IS THE EXPERIMENTAL GROUP.

Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.

Explanation:  

The whole digestive tube is approximately eleven meters long, from the mouth to the anus.

The small or thin intestine is the longest organ of the digestive tube. It can reach up to 7 meters long, up to 3 centimeters in diameter, and it characterizes by being folded. These folds are called villi, they project into the intestine light, and they are more concentrated in the first portion of the intestine, the duodene, decreasing to the final region of the organ.

Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.

The small intestine receives food from the stomach, and through peristaltic movements, it mixes and carries the material to different regions in the organ. The complex polymeric molecules are digested and transformed into simpler substances. The duodene receives secretions from intestinal glands such as bile and pancreatic juices and mixes them with digestive juices of its production. All of these secretions carry huge amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids. The intestine walls are covered by villi that increase the absorption surface area. Nutrients are absorbed by primary cells and transported to the bloodstream. Calciform cells secrete mucus to protect the epithelium during digestion. Villi also transport water from the blood to the intestinal tract, which helps in food decomposition. Enteroendocrine cells secrete hormones to the blood vessels and capillaries that enter each villus. When nutrients are small enough they go to enter the bloodstream.

Peyer's patches are nodules or cumulus of lymphatic tissue and other accessory cells, located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine, in the jejunum region. These patches represent the mucosa´s immunity system. In the jejunum, these follicles are isolated from each other in the intestine and low concentrated. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.
