Hey, there!!
The teacher is surely describing about kingdom Plantae. Plants and animals posses some similar characteristics such as eukaryotic, multicellular, in the above descriptions. BUT;
The reason for above answer is,
Plants only produce food by themselves in presence of sunlight and chlorophyll. So, they are termed as autotrophic in nature.Similarly, plants cell only posses cellwall made up of cellulose.Hope it helps....
has experienced shortness of breath during the last 3 months. A magnetic resonance scan found a small endocrine-secreting mass centrally located in her chest. This mass most likely represents a mass of which gland?
Answer: Thymus gland
Explanation:
The thymus gland is an endocrine gland that is located in the upper part of the human chest. It is responsible for producing white blood cells. This gland is located near the airway. The enlargement of the thymus gland can suppress the nearby structures. This may result in shortness of breath, and cough along with sputum. The thymus gland produces several endocrine hormones like thymopoietin and thymulin.
The given condition is indicative of the mass of the thymus gland.
Which best describes the role of a primary consumer in a food web? Carnivore that feeds on producers Herbivore that feeds on producers Herbivore that feeds on primary consumers Carnivore that feeds on primary consumer
Answer: the answer is b I’m taking the test and I got it right
Explanation:
The statement that best describes the role of a primary consumer in a food web is as follows:
Herbivore that feeds on producers.Thus, the correct option is B.
What is the Food web?The Food web may be defined as the arrangement of the number of food chains inter-connected with each other forming a web-like pattern. In a food web, one organism can hold more than one position. Instead of a straight line, it comprises branching lines.
Plants are generally referred to as producers. Those organisms derive energy by direct consumption of producers (plants) and are known as primary consumers.
Primary consumers are also known as herbivores. Secondary consumers eats and derive energy through the consumption of primary producers. Then, it comes to tertiary consumers.
Except for primary consumers, all other consumers are called carnivores.
Therefore, the correct option for this question is B.

Is a robot an open, closed, or isolated system?
EXPLAIN WHY.
Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.

Explanation:
If you're reading the 01.02A Chemistry of Life (Honors) course, go to the section called "Carbohydrates" Then go to the very last part of the section there you will find a sentence that says " They are all polymers made up of hundreds to thousands of glucose molecules bonded together, but the difference in their structures gives them different properties and functions." That's the sentence that I used to respond to this question.
Which of the following terms can refer to all life activities on a chemical level?
a reproduction
b metabolism
C development
d homeostasis
Answer:
b metabolism
Explanation:
Metabolism is a concept that encompasses the totality of the chemical reactions that take place within biological systems, which are required to sustain life. Especially, the term metabolism makes reference to the chemical reactions used by organisms to convert food into energy. Moreover, reproduction and development are metabolic processes that allow organisms to perpetuate their existence, while homeostasis is the potential that organisms have in order to maintain a stable, relatively constant internal state.

what is the color of the sky?
Answer:
the color of the sky is actually violet
Explanation:
The human eye doesn't see individual wavelengths. Instead, the retinas of our eyes have three types of color sensitive cells known as cones. One type is most sensitive to red wavelengths, while the other two are most sensitive to green and blue wavelengths. When we look at something and the light strikes our retina, the strength of signal from each type of cone allows our brains to determine the colors we see. These colors roughly correspond to the actual wavelengths we see, but there are subtle differences. While each type of cone has its peak sensitivity at red, green, or blue, they also detect light of other colors. Light with "blue" wavelengths stimulate blue cones the most, but they also stimulate red and green just a little bit. If it really was blue light that was scattered most, then we'd see the sky as a slightly greenish blue.

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration (which is responsible for acidity) ten times greater than a pH of 4. How many times greater is the hydrogen ion concentration of a pH 2 solution than a pH 6 solution?
Answer:
The correct answer is: a pH 2 solution has a 10000 times greater hydrogen ion concentration than a pH 6 solution.
Explanation:
The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.
A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.

When you go to make yourself a sandwich, you notice that the bread has mold on it. Yuck. You decide to find out which brand of bread lasts the longest without molding. You buy 8 brands of bread and leave them on the counter. You record how long it takes for mold to form.
What is the INDEPENDENT variable in this experiment? *
Your answer
What is the DEPENDENT variable in this experiment? *
Your answer
What are the CONSTANTS in this experiment? *
This is for a Grade :,
Answer: Independent variable - brands of bread; dependent variable - how long it takes for mold to form; constant - bread that's not on the counter but in the fridge (or wherever it's supposed to be) instead
Explanation:
The dependent variable is the one that DEPENDS on what will happen. How long it will take for mold to form DEPENDS on the brand of bread.
The thing that is being "depended on" is the independent variable so that would be the brands of the breads.
The constant is the part of the experiment that always stays the same. Here, we aren't really given a constant so we can assume it would be the bread that's in its original position (in the fridge), untouched, so you can compare it with the other experiments (breads on the counter).
Hope this helps!
Part C If you were the head of an ocean conservation program, what concerns would you have about implementing this method of coral regeneration?
Answer:
It causes no pollution.
Explanation:
The first concern about implementing the method used for coral regeneration is that it causes no water pollution in order to protect the other aquatic animals from the harmful effect of the method used for restoration. If the harmful effect of coral regeneration is higher and disturbing so it must be avoided in order to save other organisms but if there is no harmful effect of the method used for coral regeneration so it must be used.
Answer:
One concern I have is the metal frames. I wonder if they could damage the natural coral in the region or if fish and other sea animals could become trapped in them.
