Answer:

1. mushroom

2. nucleus

3. eukarya

4. animalia

5. button mushroom

Explanation:

1. Mushroom because everything else in the list is an animal, while a mushroom is a fungi.

2. Nucleus because eukaryotic and prokaryotic are types of formations of a cell, while a nucleus is part of a cell and not a cell formation.

3. Eukarya because the Eukarya include all animals, plants, fungi, and protists. These organisms are eukaryotes, meaning they have membrane-enclosed nuclei within their cells. The Bacteria and Archaea are both considered prokaryotes, because their cells lack true nuclei, meaning a membrane does not enclose their genetic material.

4. Animalia because fungi and plantae are stationary organisms, while animalia are mobile. (ex. fungi and plantae= roots and animalia= feet/ not attached to one place)

5. Button mushroom because sunflowers and oak trees are producers, while a button mushroom is a decomposer.

Which situation is a good example of the transfer of energy through radiation?


A. Energy passes from one person’s hand to another person when they shake hands.
B. A snake’s body temperature increases when the snake lies in the Sun.
C. Warm air that is less dense rises to the ceiling of a room.
D. A fan cools the CPU in a computer.

Answers

B. a snake’s body temperature increases when the snake lies in the sun

Radiation has been the mode of thermal energy transfer from a source. "A snake’s body temperature increases when the snake lies in the Sun" is an example of radiation. Thus, option B is correct.

What is radiation?

Radiation has been the type by which the thermal heat energy passes from the source to the other site. It has been independent of contact and involves traveling in space with the equivalent speed of light. Unlike conduction and convection, radiation does not need matter.

The particles tend to move in space like the sun's rays heating the earth. When a snake lies in the sun its body temperature rises due to tradition as the solar energy from the sun (high temperature) moved in space to the lower temperature (snake's body).

Therefore, option B. heating the snake's body under the sun is an example of radiation.

Suggest why a cell within the trunk of a tree cannot carry out photosynthesis.​

Answers

Answer:

The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.

Explanation:

The trunk of a tree consists of dead tissues and serves only to support the weight of the tree crown. This portion of the tree does not contain chloroplast, hence photosynthesis is not carried.

What is Photosynthesis?

Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

The part of the trunk region of the tree does not have chloroplast, chlorophyll pigments, and other required machinery which is significantly utilized by the leaves of the tree in order to perform photosynthesis. Due to this, the trunk part of the trees is not capable to carry out the same process.

Therefore, the most prominent reason why a cell within the trunk of a tree cannot carry out photosynthesis is well described above.

Why does herding help a horse survive better?

Answers

Answer:

In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.

Horses live in herds so they can protect themselves from danger, they would have a less chance of getting hurt if there is more of them. Another reason is because they are better able to fill there needs by being in a herd, they don’t like being alone and they are social animals. Horses are happier when they are in a herd.

Because the bodies of animals contain carbon molecules, the animal kingdom stores huge amounts of carbon. Which of the following processes returns carbon from this vast reservoir to the active carbon cycle?

Answers

Answer:

burning fossil fuels and decomposition of dead organisms

Explanation:

A significant amount of the carbon in the biosphere is returned to the carbon cycle through decomposition by fungi and bacteria. Much of what is not decomposed becomes fossil fuels. When humans burn fossil fuels for energy, carbon is returned to the atmosphere.

The process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A, as when an animal dies, its body is broken down by decomposers, such as bacteria and fungi.

What is decomposition?

The decomposition process is essential for the cycling of carbon in the environment. When an animal dies, the organic molecules that make up its body become available to decomposers. These decomposers use enzymes to break down the complex organic molecules into simpler compounds, such as sugars, amino acids, and fatty acids.

Hence, the process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A.

Compare and contrast bodily reactions driven by two parts of the ANS: the sympathetic nervous system and the parasympathetic nervous system. Provide examples where each system would be highly active.

Answers

Difference

The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.

Examples of parasympathetic responses

An easy acronym to remember how and where the PSNS works is SLUDD. This stands for:

Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.

Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.

Urination: The PSNS contracts the bladder, which squeezes it so urine can come out.

Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.

Defecation: The PSNS constricts the sphincters in the intestine and moves digested food material down the digestive tract so a person can have a bowel movement.

Examples of the Sympathetic Nervous System Response

The classic case of SNS response is a physical danger, especially with a potential predator, and the preparation of the body for either fight-or-flight. The overall system is designed to enhance voluntary muscle activity while shutting down all non-essential functions.

Arterioles and veins in most vascular beds constrict, reducing blood flow to the skin and digestive organs. Sphincters in the digestive organs also constrict, to control the flow of food from one organ to the next. However, coronary blood vessels, pulmonary circulation and parts of the respiratory tree respond with dilation, to enhance cardiac output. The heart beats with greater contractile force and at a higher frequency as well. Vasoconstriction in many parts of the body also increases blood pressure.

Similarity

Both are the part of ANS. Both originate from the spinal cord. Both have huge influence on physiological process of the body such as respiration, circulation, digestion, urination and reproduction.

The SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.

The autonomic nervous system (ANS) comprises the sympathetic system and parasympathetic system.

The sympathetic nervous stimulates 'fight or flight' responses, whereas the parasympathetic system activates 'rest and digest' responses.

The sympathetic nervous system is involved in body reactions such as the acceleration of the heart, constriction of the blood vessels, etc.

The sympathetic nervous system is involved in body reactions such as lowering the heart rate, lowering the flow of blood to skeletal muscles, etc.

Some examples that activate the parasympathetic system include:

Get a massageMeditationSlow breathing

Some examples that activate the sympathetic system include:

StressOverstimulation

In conclusion, the SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.
