What information cannot be studied effectively using human torso models? I. the approximate sizes of organs II. the textures of organs III. the interrelationships of organ functions IV. the positions of organs within the body
Answer:
II. the textures of organs
Explanation:
A human torso model is designed to be as accurate as possible so that students/researchers can understand the inner workings of the body. Therefore, the organs have been designed to be the same size of an actual human being of that stature, while also being in the correct position within the body to better understand the interrelationships between the organs. The only thing that is not accurate in these models is the texture of the organs as most are smooth plastic unlike the actual organs.

Secondary succession can happen after primary succession or independently of primary succession.
Please select the best answer from the choices provided
ОТ
OF
Answer:
it is true
Explanation:
i took the quiz
False. Secondary succession does not happen after primary succession or independently of primary succession.
What is secondary succession?Secondary succession is the process of ecological succession that occurs after a disturbance has disrupted an existing ecosystem, but left some soil and seed sources intact. Unlike primary succession, which starts with bare rock or soil with no living organisms, secondary succession begins in areas where there was already an established community of plants and animals.
Examples of disturbances that can lead to secondary succession include forest fires, landslides, and farming practices that disturb the soil. The process of secondary succession involves the gradual recolonization of the area by plants and animals, with different species replacing one another as the ecosystem gradually returns to a stable state.

To test the effectiveness of a new nutrient supplement, one group of identical mice is given the supplement, and the other group is not given anything. Which is the most complete list of the parts of an experiment presented in this scenario? independent variable, dependent variable control group, experimental group, dependent variable independent variable, control group, experimental group control group, experimental group
Answer:
The answer is the second option: Dependent variable, experimental group and control group
Explanation:
Let's list out all possible variables/groups in the option
Independent variable: This is a variable that is intentionally (directly or indirectly) altered by the one doing the experiment but is not affected by any variable/group during the course of the experiment. No Independent variable was mentioned.
Dependent variable: This is a variable that is affected by another variable and is usually the variable been tested during the course of an experiment. The dependent variable here is the effectiveness of a new nutrient supplement.
Experimental group: This is the group that is being treated during the course of an experiment. The experimental group here is the group of identical mice given the supplement.
Control group: This is a reference group that is not given any treatment during the course of an experiment. The control group here is the group of identical mice not given anything.
From the above description, it can be deduced that the parts of the experiment described in the scenario in the question is dependent variable, experimental group and control group.

 what are the similarities and differences between Atoms and molecules?
Answer:
Physical matter is made up of atoms and molecules. An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.
Hope this helps :)
Explanation:
Difference
atom is the smallest unit of an element that can or cannot exist freely whilst on the other hand, a molecule is a set of atoms that are held together with the help of a bond and is the smallest unit of a compound.
Similarities
both atoms and molecules react with each other and other molecules and atoms.

Explain- the 8 characteristics that are required for life
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.
Explanation:
Sensitivity or Response to Stimuli
Organisms can respond to diverse stimuli. For example, plants can grow toward a source of light, climb on fences and walls, or respond to touch. Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light (phototaxis). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is considered a negative response.
Reproduction
Single-celled organisms reproduce by first duplicating their DNA. They then divide it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germline cells that will form new individuals. When reproduction occurs, genes containing DNA are passed along to an organism’s offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, such as size and shape.
Growth and Development
All organisms grow and develop following specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young will grow up to exhibit many of the same characteristics as its parents.
Regulation
Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses. Two examples of internal functions regulated in an organism are nutrient transport and blood flow. Organs (groups of tissues working together) perform specific functions, such as carrying oxygen throughout the body, removing wastes, delivering nutrients to every cell, and cooling the body.
Homeostasis
In order to function properly, cells need to have appropriate conditions such as proper temperature, pH, and appropriate concentration of diverse chemicals. These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through homeostasis (literally, “steady state”)—the ability of an organism to maintain constant internal conditions. For example, an organism needs to regulate body temperature through a process known as thermoregulation. Organisms that live in cold climates, such as the polar bear, have body structures that help them withstand low temperatures and conserve body heat. Structures that aid in this type of insulation include fur, feathers, blubber, and fat. In hot climates, organisms have methods (such as perspiration in humans or panting in dogs) that help them to shed excess body heat.
Energy Processing
All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food; others use chemical energy in molecules they take in as food.
Evolution
As a population of organisms interacts with the environment, individuals with traits that contribute to reproduction and survival in that particular environment will leave more offspring. Over time those advantageous traits (called adaptations ) will become more common in the population. This process, change over time, is called evolution, and it is one of the processes that explain the diverse species seen in biology. Adaptations help organisms survive in their ecological niches, and adaptive traits may be structural, behavioral, or physiological; as such, adaptations frequently involve other properties of organisms such as homeostasis, reproduction, and growth and development.
