Answer:
D
Explanation:
All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.
What are nonnative species?Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.
Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.
They are employed in restocking efforts, to replace native species, and for commercial purposes.
Thus, the correct option is D.

a student observed a food sample that’s left a greasy spot on paper and also gave a positive test for starch. which two organic compounds are present in the food sample ?
Answer:
The correct answer is - fats and carbohydrates are two organic compounds that are present in the sample.
Explanation:
The greasy spot present on paper shows that there are fats present in the food sample that can be butter, ghee, or oil. Fats are the organic compound that provides energy to the organism that eats fat, however, more than a limit fat is harmful to any person.
The starch test suggests that food samples have starch present in the sample, starch is nothing but a polymeric carbohydrate. Carbohydrate is a basic organic compound that provides energy to the body or different organism.
Thus, the correct answer is - fats and carbohydrates.
Explain the relationship between photoshnthesis and cellular respriation. Be sure to include the main purpose of both and where they occur inside the cell
Answer:
photosynthesis occurs in the chloroplast of plant cells. cellular respiration starts in the cytoplasm then reacts in the mitochondria. if you look at the chemical equation of both photosynthesis and cellular respiration they are reverse of each other. in cellular respiration sugar goes in with oxygen, what comes out is ATP(energy), water, and carbon dioxide gas. in photosynthesis energy, water, and CO2 goes in and what is made is sugar and oxygen. The main purpose of cellular respiration and photosynthesis is to make energy and to store energy for later use.

A family went on vacation for a week and was unable to water their houseplants. When the family returned their houseplants had wilted, droopy leaves What the best explanation for this observation?
Answer:
They should have hired someone to water their plants.
Explanation:
As the family goes on vacation for a week, there is not one who can water the houseplants. As the result, the plants undergoes wilting and will finally die.
What is wilting of plant?The wilting of plants is the loss of rigidity of non-woody parts of plants. This occurs due to the turgor pressure in non-lignified plant cells which falls towards zero, as a result of diminished water in the cells. Wilting serves to reduce the water loss, as in this process the leaf reduces in size which makes the leaves expose less surface area and hence reduced water loss.
Plants wilt when the roots are unable to supply sufficient moisture to the stems and leaves of the plant. Wilting for a short period of time does not harm plants, however continuous can lead to death of a plant. Sometimes a plant wilts on a hot day as the moisture is evaporating from the leaves faster than the roots can take it up from the soil.

Compare and contrast characteristics and use his own diodes and triodes
Answer:
Comparison of characteristics and use of diodes and triodes is given below:
Diode and triodes both are electrical components but diode allows the flow of current in only one direction while triode has three electrodes.Diode consists of two terminal (anode and cathode) while Triodes have three terminals (cathode, anode, and grid). A diode is an electrical component used to control voltage while triode is a current controlled device. Diodes used in modern electronics such as LED while triodes are used in RF heating systems.Answer:
1. Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
2. Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.

Which student, if either, is most correct in their claim regarding the ATP/ADP cycle?
A. Brianna's claim is correct - the removal of a phosphate group (or the breaking of
a chemical bond) supplies a great deal of energy from the cell and the ATP/ADP process is not continuous.
B. Neither student is completely correct. Oscar is correct in that this process is a
cycle and Brianna is correct in that the removal of the phosphate group supplies the most energy
C. Oscar's claim is correct - the addition of a phosphate group (or the making of a
chemical bond) supplies a great deal of energy from the cell and the ATP/ADP
cycle is continuous.
D. Both students are correct - Oscar's claim is correct for the process of
photosynthesis and Brianna's claim is correct for the process of cellular
respiration.

I NEED HELP , WILL GIVE BRAINLIST:
1.Write a brief essay comparing the process of resiration with the process of photosynthesis.
Photosynthesis is carried out by plants, alga, and blue green bacteria. It takes the energy from the sun and puts it into the bonds of sugar molecules. Photosynthesis only stores energy in food (glucose), we use respiration to get the energy out of food.
Respiration: Process that takes energy from sugar molecules and places it in molecules of ATP
Aerobic Respiration requires oxygen, and yeilds more ATP for a molecule of sugar than anaerobic (no oxygen) respiration.
Photosynthesis and Aeorbic Respiration are opposite reactions. They are also important in cycling oxygen, carbon, hydrogem and water through the environment.

The average size of a grocery store chicken has more than doubled in the past century. What is the most likey reason for this change?
A. Natural selection resulted in a larger species of chicken.
B. Artificial selection created a larger breed of chicken.
C. Mutations occur less frequently in chickens than they did a century ago.
D. Grocery stores used to sell younger chickens.
Answer:
B, artificial selection resulted in a larger species of chicken.
Explanation:
People breed the largest animals (in this case chickens) or plants to improve agriculture.
Hope this helps! ;)
The average size of grocery store chicken has more than doubled in the past century because artificial selection created a larger breed of chicken. The right option would be B.
Artificial selection refers to deliberate actions by humans to selectively breed organisms based on desired traits.
Because big size chickens are desirable for their meats, breeders and genetic engineers would select this trait and favors it over other alternate traits using appropriate scientific procedures (such as controlled mating). Thus, chicken with undesirable traits gradually fades off the population while those with desirable traits are made to thrive.

Papaya plantations in Hawaii have recorded cases of a virus that decreases the health of the papaya plants. To combat the virus, genetic engineers have developed a papaya plant that has the DNA of the virus, making the plant immune to the effects of the virus. Which is a likely concern for farmers about the genetically modified papaya plants?
Answer: Concerns were the health risk associated with those who will eat Genetically modified papaya.
Explanation:
Scientists tried to make a genetically modified papaya in Hawaii because papaya industry was dropping drastically due to PRS virus infection and thousands of farmers had lost their jobs. Then the scientist genetically modified papaya plants by inserting virus resistant genes. This helped a lot in producing disease free crops.
The main ethical concern of farmers was to understand the health risk associated with the crops which are genetically modified with viral genome could cause health complications to consumers.
