Which action would most likely increase the amount of carbon in the environment? A. Choosing to burn coal to generate electricity B. Using energy-efficient appliances in place of older, traditional appliances C. Reusing shopping bags instead of using disposable plastic bags D. Recycling paper and plastic instead of throwing it in the trash
Answer:
Choosing to burn coal to generate electicity
Explanation:
Burning coals to generate electricity is most likely to increase the amount of carbon in the environment because it emits carbon dioxide, hence option A is correct.
Why does burning coals increase the amount of carbon?When coal burns its carbon is combined with oxygen to produce more amount of carbon dioxide, for generating electricity coal burns is producing a large amount of carbon.
If fuel burns its oxygen reacts with carbon in the air forming carbon dioxide or reacts with hydrogen to form water vapor.
Using energy-efficient appliances in place of older, traditional appliances, has less chance to produce excess amounts of carbon in the environment. Recycling things also reduces the amount of carbon in the environment.
Therefore, choosing to burn coal to generate electricity is the correct option.

Silk is used in various products such as clothing, tires, parachute and surgical suture etc. When the silk is sold at good price, it automatically better the economic conditions of both the individuals who done rearing of silk and the country also earn money by export to other countries.
Do you have reason to suspect that they should become isolated on the same dilution plate
Answer:
Please see below
Explanation:
Since the bacteria Serratia marcescens kept on growing even with higher dilution levels, it can safely be concluded that no, E. coli and S. marcescens would not become isolated on the same plate. The inoculum used should roughly contain 300 cells in order for it to not grow in clumps, rather make separate colonies.

All living things respond to stimuli.
All living things maintain homeostasis.
All living things adapt to changes in their environment.
All living things contain genetic material and reproduce.
The correct answer would be that all living things adapt to changes in their environment.
Generally, all living organisms try to adapt to changing environments. Those that are able to successfully adapt survive in the environment and are able to produce offspring that are also able to survive in the same environment. Organisms that are not able to adapt to a changing environment end up dying from the population. This is an example of evolution by natural selection - the survival of the fittest.

Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer: In contrast to human stance control, robot stance control is at an early stage of evolution. The need for some form of stance control system has been recognized during the recent rapid development of humanoid robots (see Mahboobin et al., 2008). However, the design of most robot balance systems has not taken advantage of existing knowledge of human stance control systems. A possible reason for this is that engineers focused on the obviously important interaction that occurs at the interface between the robot’s feet and the ground

what is eco system?write with an examples.
Answer:
a biological community of interacting organisms and their physical environment.
Explanation:
Hey, there!!
We generally define eco-system as the ecological unit which consists of both biotic and abiotic components. It is area where various type of plants, animals and non- living structures are found. Various organisms and environmental factor collectively forms an eco-system.
Example: sun gives light and plants prepare their food which later on animals consume to get engry. In this way they interact with eachother.

Explanation:
Most endocrine tissues use a negative feedback mechanism for homeostasis. Which of the following involves a positive feedback mechanism? Group of answer choices cortisol insulin oxytocin thyroid
Answer:
The correct answer is: Oxytocin.
Explanation:
Feedback mechanisms are key elements in the regulation of hormone release and, in the human body, most endocrine systems work by making use of negative feedback, which means that the response generated by the release of the peripheral hormone (for example, insulin), will lead to an inhibition of the stimulus that made the release of said hormone possible - this is very important to control homeostasis.
Positive feedback, on the other hand, is the opposite. This type of feedback mechanism, which is not as common as negative feedback, happens when the peripheral hormone is released and this stimulates the tissue that released the hormone that stimulated the release of the peripheral hormone - this is done so the hormone effect is amplified more and more.
To better illustrate these mechanisms, here are some examples of each:
Insulin. After having a meal, the blood sugar levels rise, which triggers the release of insulin, a hormone that decreases blood sugar levels (glycemia). When this decrease in glycemia is produced, the release of insulin is stopped. This is negative feedback. Cortisol and thyroid hormones are also examples of negative feedback.Oxytocin. This hormone is released from the posterior pituitary gland during labor to produce the contractions of the uterus, which will push the baby through the birth canal. The presence of oxytocin will lead to the release of more oxytocin, so the muscle contractions can increase. This is an example of positive feedback.which shows a correct order of steps in the scientific method?

A Mars-sized planetesimal collides with Earth. Molten material is ejected from EarthMaterial accretes to form the MoonThe Moon begins rotating and revolving around EarthIt begins with a collision. Once the material is ejected away from the earth, it will come together to form what we call as the moon. After formation, it id held within the gravitational field of the earth and it begins to revolve around it because of that.
What is you were an astronaut and interplanetary explorer and you discovered “something” on another planet,like Mars that reproduced by itself, grew in size, took in food, responded to you or other stimuli, but did not seem to be made of cells or possess DNA or RNA. would you consider it to be living or nonliving?
Answer:
I would consider it to be nonliving
Explanation:
The characteristics of life demarcates a living thing from a nonliving thing. These characteristics include the ability to move, ability to respire, ability to reproduce, ability to undergo nutrition (take in food), ability to respond to external stimuli, ability to grow by increasing in size and more importantly must be made up of at least a single cell. Cell is the fundamental and basic unit of all living things.
This object found in Mars may be able to perform every other characteristics of a living thing e.g reproduction, irritability, growth, nutrition etc but to be considered as a living thing, it must consist of at least one CELL, which in turn must contain either a DNA or RNA molecule that carries information about its genetic content.
Hence, according to the universal CELL THEORY that states that "All living things contains one or more cells", this something found on Mars is not considered living.

Science
Directions: Read the given scenarios below. Identify each required component for
each scenario.
Scenario 1:
A student is studying how far room temperature water would squirt out of a plastic
milk carton when 4 mm holes are punched at different heights from the bottom of
the container
Describe which are the independent and dependent variables as well as indicates
the constants involved within the experiment and why those are the constants.
Independent Variable:
Dependent Variable:
Constants:
Answer:
Independent variable: height of holes
Dependent variable: distance of squirting water
Constant: size of holes punched into the milk carton
Explanation:
The independent variable is one whose value is often manipulated during the course of experiments and the effects produced by the manipulation is measured on the dependent variable.
The dependent variable is the actual variable that is being measured in the course of experiments. The value of the dependent variable is affected by changing the values of the independent variable.
Constants are variables whose values remain unchanged throughout the course of experiments.
Hence, in the illustration:
Independent variable: the height of holes on the milk carton
Dependent variable: distance of squirting water
Constant: the size of holes punched into the milk carton
how are extrusive and intrusive rocks alike
Answer:
Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form.
Explanation:
intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and periodontist. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals.
