is a simple representation of a more complex system.
Answer:
A model scientific is a simple representation of a more complex system.
Explanation:
The scientific model is a simplified representation of scientific systems that are more complex or impossible to see by the human eye, such as an atom or a solar system. Although this representation is simplified, it has the responsibility to produce all the essence, content and behavior of the original systems, thus allowing the models to be used in scientific studies and research and to promote concrete results that provide accurate information about the original systems.
What do you feel really got the biotech industry started and how was it different from what came before it? g
Answer:
When the human being realized that he could use living beings or their derivatives to produce products of human interest on a large scale, the biotech industry started. This sector was different from what existed before it, because it used tiny elements such as proteins, bacteria and DNA, to manufacture the products.
Explanation:
As you may already know, biotechnology is the science that allows the use of living beings and their derivatives for the manufacture of biological products much needed in human daily life. Biotechnology has been used since the beginning by mankind. This can be seen in the manufacture of bread and wine, for example. However, this science only became something industrial, when the human being realized that it was advantageous to use organisms for the production of products on a large scale.
This was an industrial innovation, since until then, the industry did not use organisms and elements so small for the production of its products.
You have formulated a hypothesis: "Mangos contain more vitamin C than oranges." To test your hypothesis you measure vitamin C levels in 20 oranges and 20 mangos from trees that were grown in the same orchard under the same environmental conditions (temperature, rain, sunlight). What is the independent variable in this experiment?
Question options:
A) The amount of rain and sunlight the trees received
B) Vitamin C levels
C) The type of fruit
D) The type of soil the trees grew in
Answer:
B) the type of fruit
Explanation:
The independent variable is the value that the experimenter changes/controls. The Vitamin C levels depend on the type of fruit, so the fruit is the independent variable. Hope this helps!
The value that the experiment modifies or controls is known as the independent variable. Fruit is the independent variable because fruit types vary in their quantities of vitamin C. Thus, option B is correct.
What is the independent variable?“X” is frequently used to indicate an independent variable. It is a variable that is independent of other variables.
The elements or circumstances that you can change in an experiment are referred to as independent variables. A dependent variable's value may be directly impacted by this variable.
The definition of an independent variable is exactly what it says. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable.
Anticipated to have an impact on the dependent variable. The experiment has no effect on this. It is a variable that can be altered by researchers to examine the independent variable.
Therefore, fruit is the independent variable, to vary in their quantities of vitamin C.

Answer:
D.ability or inability to do photosynthesis
Explanation:
Because feeding is one of the features of living things and green plants feed by photosynthesis which is the process where by they convert light energy to chemical energy in the presence of chlorophyll
Answer:
D
Explanation:
Classification in living things can be done using different factors, the system of classifying living thing scientifically is called taxonomy.
The ability of an organism to photosynthesize is one of the main characteristics of classifying.
All green plants, some bacteria and Algae that has chlorophyll content photosynthesize to produce their own food, this makes them less dependent but a primary producer.
This ability to is used to differentiate between photosynthetic organisms and non photosynthetic organisms and also help classify living organism

Explanation:
A transverse section of the thorax has been attached as an image herein.
The thorax is essentially the chest area of the organism's body. Inside the thoracic cavity, the serous membranes (known as pleurae) are responsible for separating the lungs from the boundary of the thorax. Visceral pleura is present on the external side of the lungs. The parietal pleura is present on the inner side of the thoracic cavity and the diaphragm. In between the 2 pleurae, there is a lining of serous fluid present.
Which of the following accurately describes the thermocline profile along the equator?
A. Due to constant temperatures, there's no thermocline in the tropical region. .
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
C. Due to constant temperatures, there's no thermocline in the polar regions.
D. The thermocline stays relatively stable throughout the year.
Answer:
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
Explanation:
Storms occurs on that locations where there is high temperature and high temperature is only present at the equator due to direct sunlight. So we can say that maximum storms comes at and near the regions of equator. The oceans present near the equator have a warm layer known as thermocline from where water is evaporated and the intensity of storms are also increases.

What adaptations would a plant species need to encounter the effects of an herbivorous insect and what adaptations would the insect need to counter those defenses?
Answer:
The plant defense system incorporates waxy cuticles or bark that are impenetrable in order to protect from insects. They can create complex polymers that lower the plant absorbability to creatures; and poisons that can kill herbivores and insects. Furthermore, plants produce hard shells, and spines (changed leaves), and thorns to shield themselves from herbivores.
Herbivores then again have built up a various scope of physical structures to encourage the utilization of plant material. They have created teeth structures to penetrate or break plant tissues and that mirror their taking care of inclinations. They can create proteins, for example, oxidases (MFOs) and protease that counter and diminish the adequacy of various harmful auxiliary metabolites delivered by plants. They can maintain a strategic distance from plant protections by eating plants specifically in reality.
