5 0

This question is incomplete, the complete part of the question containing the students definition and teacher's comment is:

Ruby's definiton: A 3-dimensional shape whose boundary consists of all points equidistant from a fixed point (the center).

Shriya's definition: The set of all points in a 2D plane such that for every point in the set there is exactly one other point in the set that is d (call it diameter) units away.

Abhishek's definition: The set of all points in a plane that are the same distance (radius) away from some given point (center).

Teacher's comments:

Are you thinking of a sphere?

You are correct. Nicely done!

This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle.​

THE ANSWERS ARE:

Ruby's definiton: Are you thinking of a sphere?

Shriya's definition: This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle.​

Abhishek's definition: You are correct. Nicely done!

Explanation:

A circle is a two-dimensional round plane shape (2D shape) whose boundary line called the circumference has several points that are of the same distance (radius) from the centre point of the shape.

Based on this definition of a circle, the answers given by each students will now be reviewed.

1). Ruby's definiton: This definition is wrong because a circle is not a 3D shape. The definition is describing more of a SPHERE, which is a 3D round shape in a space. Hence, the teachers comment will appropriately be; Are you thinking of a sphere?

2.) Shriya's definition: This definition is wrong because it is not describing a circle, rather it is describing a part of a circle (diameter). Hence, the teachers comment appropriate for this answer is: This is incorrect. For example, your definition also allows for the following shape, which is just part of a circle

3). Abhishek's definition: This definition correctly describes a circle, hence, the teacher's comment will be: You are correct. Nicely done!

Setler [38]

Answer:

b. cladophora

Explanation:

The cladophora algae is a type of green algae that grows attached to rocks or wood that are underwater. It forms short, rigid green filaments that branch, it's smell is similar to mushrooms. The cladophora is introduced in aquariums via contaminated plants or equipment, therefore to prevent it's formation it is necessary to clean everything before intoruducing it to the aquearium. This algae is so resistant once installed that usually the tank has to be re-started.

What are TWO functions of citric acid in the feta cheese? What are the TWO functions of agar in the feta cheese?
Vinvika [58]

Answer:

The following are the two functions of citric acid in the feta cheese:  

1. Coagulation, that is, the chemical reaction of citric acid with proteins in milk leads to separation of curd and whey.  

2. The citric acid functions as a chelating agent, which is required for syneresis, that is, for controlling the moisture content.  

The following are the two functions of agar in the feta cheese:

1. Feta means to slice, and agar offers sliceable texture to the feta cheese as it produces a solid gel-like composition.  

2. It is a vegetarian alternative for gelatin and exhibits higher gelling properties.

What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP
Nady [450]

The given question is incomplete, the complete question is:

During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions. Condition Rate of carbon dioxide produced (mL/min) Germinating peas, 10ºC 0.01 Germinating peas, 20ºC 0.02 What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production. Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production. Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC. The rate of cellular respiration cannot be measured without knowing the rate of ATP production.

Answer:

The correct statement is that at 20 degree C, the germinating peas exhibits a higher rate of cellular respiration in comparison to the germinating peas at 10 degree C.

Explanation:

The process of respiration results in the production of carbon dioxide, respiration refers to a chemical reaction that generates water, carbon dioxide, and energy by undergoing oxidation of the glucose molecules. This phenomenon plays an essential role in the life of the organisms for obtaining energy from the food they consume to perform daily activities.  

From the question, it is evident that the peas, which were germinating at 20 degrees C exhibit a higher rate of cellular respiration as they are generating 0.02 milliliters of carbon dioxide in a minute, while on the other hand, the germinating peas at 10 degrees C are giving rise to 0.01 milliliters of carbon dioxide in a minute.
