Which best describes the relationship between two species and a niche?
If two species have the same niche, one species will always become extinct.
Two species are able to occupy the same niche in the same habitat.
Two species cannot occupy the same niche in the same habitat.
If two species have the same niche, one species will always move.
Answer:
If two species have the same niche, one species will always move.
Explanation:
In biology, ecological NICHE refers to how the species of an organism performs in its ecosystem i.e. its role. Niche includes the reproduction, feeding pattern, prey, etc. However, if there are two species occupying the same niche, one species will always move.
One of the species, usually the weak one, will always move because occupying the same niche by two species will inevitably lead to competition, which causes one of the species to go elsewhere when these resources are limited.
Answer:
C.) Two species cannot occupy the same niche in the same habitat.

Explanation:
The given diagram shows the process known as Photosynthesis and the primary source of energy for this process is the Sun. Thus, the correct option is D.
What is Photosynthesis?
Photosynthesis is a process by which plants make their food. Plants and other organisms convert light energy into chemical energy by this process that later can be used to fuel the organism's activities.
In this process, plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Plants transform carbon dioxide into oxygen with the help of sunlight and animals need oxygen to survive. Plants also fix carbon dioxide by checks the air quality.
In plants, photosynthesis takes place in chloroplasts, which contain a pigment called the chlorophyll. Chloroplasts are surrounded by double membrane and contain a third inner membrane, called the thylakoid, which forms long folds within the organelle.
Therefore, correct option is D.

Often, complex molecules are described in terms of their atomic masses. But what is more relevant in biology is how they take up space. (For proteins, their shapes are particularly important.) Let's see if we can get an approximate idea of the physical size of a protein molecule by doing various estimations.
An important molecule in the internal mechanisms of cells is Actin. This is measured as having a mass of about 42 kDa (= 42,000 Daltons, where 12 Daltons is defined as the mass of a carbon atom). Let's see if we can estimate how big it is using very crude estimates. Of course eventually we will want to know how big it actually is and what its shape is, but getting a scale would help us determine what measurement tools might be appropriate.
In order to estimate the size of Actin, we'll first make an estimate of how many atoms it has, then, using the average size of an atom, we'll consider different models of how it might be arranged to get an idea of its size.
A. We could look up the chemical composition of Actin to get exactly how many atoms it contains. But let's see how "the estimation game" does instead. Actin is a biological molecule, so it's probably made up of mostly carbon, oxygen, nitrogen, and hydrogen, with a few other stray atoms tossed in. Use an "average sized biological atom" to estimate the number of atoms in Actin.
B. Given the radius of an average atom let's consider a simple model of Actin. Suppose Actin is tightly packed into a sphere or cube. For estimation purposes we could model each atom as a cube. If you built up a cube of the total number of atoms you found in A, what would be the dimensions of the cube?
C. Look up Actin and find its actual size. How did the really simple model do? Can you draw any conclusions about the structure of Actin from these results?
Answer:
b
Explanation:
The correct answer is option (B) Given the radius of an average atom let's consider a simple model of Actin. Suppose Actin is tightly packed into a sphere or cube. For estimation purposes we could model each atom as a cube. If you built up a cube of the total number of atoms you found in A, what would be the dimensions of the cube.

Explanation:
Independent variable, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a response. In this case the independent variable is the CANDY given to the children.
Dependent variable is the variable that the experimenter measures or the variable that responds to changes made to the independent variable. In this case, the dependent variable is the CHILDREN'S BEHAVIOR in response to candy.
Experimental group is the group that receives the experimental treatment in an experiment. In this case, the CHILDREN THAT RECEIVES THE CANDY are the experimental group.
Alyssa investigates properties of matter. The answer to which question would best
determine whether a substance is an element or a compound?
Answer:
This question is incomplete as it lacks options, the options are:
A) What is the radius of each particle of the substance?
B) Does the substance contain more than one type of atom?
C) Was a chemical reaction necessary to create the substance?
D) What is the electrical charge of the particles of the substance?
The answer is B
Explanation:
In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.
According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?
- If the answer is yes, the substance is a COMPOUND
- If the answer is no, the substance is an ELEMENT.
The question that would most adequately determine if a substance is an element or compound would be:
- Does the substance contain more than one type of atom?
Properties of matter
An element is defined as a chemical substance that comprises of atoms having similar proton numbers. While a compound is made of joining a minimum of two or more elements.Thus, the substance having one type of atom would be called an element while having different types of elements would be called a compound.Learn more about "Compound" here:

Why is the process for developing a vaccine usually lengthy? A. Obtaining the necessary supplies for testing is complicated. B. Recruiting scientists to work on a vaccine project can be difficult. C. Ensuring that a vaccine is safe requires multiple rounds of human testing. D. all of the above
Answer:
C. Ensuring that a vaccine is safe requires multiple rounds of human testing
Explanation:
Vaccination is the process whereby a substance called a VACCINE is administered in order to prevent a particular disease. The vaccine is actually a substance given to help the body's defense system combat a particular infection or disease. A vaccine, which is usually a harmless strain of a pathogen, prepares the antibodies of an organism to fight against the actual pathogenic organism.
As rightly said in the question, developing a vaccine can be a very long process. This is because the vaccine has to go through series of testing on healthy humans before releasing to the public in order to ascertain that there are no risks or dangers attached to the usage. The process of ensuring that a vaccine is safe requires multiple rounds of human testing, which is time-consuming.

When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate into individual sodium ions (Na+) and chloride ions (Cl-). In contrast, the atoms of covalently bonded molecules (e.g., glucose, sucrose, glycerol) do not generally dissociate when placed in aqueous solution. Which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions)?
A) 1 L of 0.5 M NaClB) 1 L of 0.5 M glucoseC) 1 L of 1.0 M NaClD) 1 L of 1.0 M glucoseE) C and D will contain equal numbers of particles.
Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
