1. **In the procedure shown below, a calcium chloride solution is mixed with a sodium sulfate solution to create the products shown. Which of the following is illustrated by this activity?
a. The law of conservation of mass
b. The theory of thermal equilibrium
C. The law of conservation of energy
d. Newton's 2nd Law
Answers
The reaction follows the law of conservation of mass since the mass remains same before and after the reaction. Therefore, option (A) is correct.
What is the law of conservation of mass?According to the principle known as the rule of conservation of mass, during a chemical reaction, mass can neither be created nor destroyed. When coal is burned, for instance, the atom of carbon that it contains transforms into carbon dioxide. The mass of the carbon atom remains constant even as it transforms from a solid structure to a gaseous state.
The study of chemical reactions, as well as their generation, places a significant emphasis on the principle of mass conservation. Scientists are able to make accurate forecasts regarding the amounts of products that will be produced from a certain reaction if they are aware of both the amounts of reactants and their identities.
Thus, in the above reaction the mass is conserved and option (A) is correct.

A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.
Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).
The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
What is DNA replication?It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.
Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.
The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.
In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.
Thus, the correct statement is the second one, that is, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

Answers
Answer:
B. 0 m
Explanation:
From the position - time graph, the object would have traveled a distance of 0m after 6s.
The graph shows a decrease in distance traveled with increasing time.
the y - axis is the position of the body the x - axis is the the time takenIf we trace up the time taken to the curve, the position will be 0m.
Therefore, the position of the body after 6s is at 0m.

If the desert experiences a prolonged drought where many of the plants die, which BEST predicts the effect on the carrying capacity of the ecosystem?
A
The carrying capacity of the ecosystem will increase because there will be more space available for organisms.
B
The carrying capacity of the ecosystem will increase because there will be fewer organisms that require resources.
C
The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.
D
The carrying capacity of the ecosystem will decrease because there will be fewer organisms competing for resources.
Answers
Answer:
c
Explanation:
there will be way less vegetation to attract pet and many organisms will die because of the lack of resources due to the drought
If the desert experiences a prolonged drought where many of the plants die, the carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.
What is ecosystem?"An ecosystem consists of all the organisms and the physical environment with which they interact."What do you man by carrying capacity?"The carrying capacity is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available."Due to draught, resources decreases (resources becomes limited) and many organisms would die because of starvation. This would also effect in the food chain of other organisms. The organism would now compete for the lesser amount of resource.
Hence, the correct option is C. The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.

A. All look the same
b. All have the same structure
c. are often quite different from each other
d. are the same size in every part of the organism
Answers
Answer:
c. are often quite different from each other
Explanation:
Multicellular organisms - composed of several different cells: Cells in these organisms differ in relation to the function to be performed.
The cells in these organisms are growing, developing, and reproducing.
The cells differ in shape, size, and role they have in the organism.
In the group of multicellular organisms are animals (Animalia), plants (Plantae), and fungi (Fungi).
Cells in many-celled organisms are often quite different from each other. Therefore option C is correct.
In many-celled organisms, such as animals and plants, cells can be specialized for specific functions, leading to their differentiation and diversification.
Different types of cells have distinct structures and perform specific tasks within the organism.
For example, nerve cells (neurons) are specialized for transmitting electrical signals, muscle cells for contraction, and blood cells for carrying oxygen and nutrients.
This specialization allows for efficient division of labor, where each cell type contributes to the overall functioning of the organism.
The diversity of cell types and their functions is a fundamental aspect of the complex organization and functioning of multicellular organisms, contributing to their overall biological complexity and adaptability.
Therefore option C are often quite different from each other is correct.
