Answer:
Option A.
Increases density as it solidifies
Explanation:
Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.
Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?
A) the different amounts of water
B) the heights of the pea plant
C) the pea plants
D) the natural ways of receiving water
Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!

Why wouldn't we wear formal attire or use forks when eating soup?
a) The motive doesn't fit the drive or the incentive.
b) Our incentives regulate the drive for proper clothing and utensils.
c) Our higher brain tells us it is inappropriate and incorrect symbolism.
d) Our lower brain alerts the hypothalamus to tell us it is wrong.
Answer: c. Our higher brain tells us it is inappropriate and incorrect symbolism
Explanation:
We wouldn't we wear formal attire or use forks when eating soup because our higher brain tells us it is inappropriate and incorrect symbolism.
The higher brain helps us to interpret vision, emotions, touch, speech, reasoning etc. Since eating soup with forks isn't appropriate, this will be detected by the higher brain. The higher brain simply performs intellectual functions.
Therefore, the answer is C.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

If a DNA strand has 23 % guanine before semi conservative replication occurs, what percent Thymine will each new strand have after replication?
Answer:
27%
Explanation:
DNA is a linear molecule composed of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Chargaff's rules state that adenine (A) always pairs with thymine (T), while guanine (G) always pairs with cytosine(C). In consequence, the amount of G should be equal to the content of C, while the amount of T should be equal to the content of A. In this case, the content of G is 23% and the content of C is also 23%, so the remaining content (A + T) is equal to 54% [100 - (23 + 23) = 54%], thereby content of A is equal to 27% and the content of T is also 27% (27 + 27 = 54%).

How does cellular respiration demonstrate
the conservation of mass?
Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:
C6H1206 + 6O2 ---- 6CO2 + 6H2O
Th number of atoms of reactants equals the number of atoms of products:
six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms
No atoms are created or destroyed in this process, they're just rearranged into different molecules.
We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
Cells use cellular respiration to convert glucose into energy for cellular function. A chemical process that, when balanced, complies with the Law of Conservation of Matter might serve as a metaphor for it:
6CO2 + 6H2O = C6H1206 + 6O2
What is cellular respiration?
Cellular respiration converts glucose into ATP, which powers various physiological functions. Cellular respiration involves glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glucose fuels cellular respiration. A balanced chemical reaction represents it:
6CO2 + 6H2O = C6H1206 + 6O2
Reactants and products have equivalent atom counts.
This technique rearranges atoms into molecules without creating or destroying them. Living creatures "burn" glucose for energy. Burning conserves matter. Because CO2 and water are gaseous, colourless, and invisible, it may seem that the burnt material is totally consumed. Antoine Lavoisier was the first to demonstrate mass conservation in chemical reactions by conducting combustion processes in a closed system and catching the gaseous products.

Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.

Answer:
mitosis, cytokinesis
Explanation:
Cell division occurs in two stages: the division of the nucleus, called karyokinesis, and the division of the cytoplasm, called cytokinesis, and both of these include cell division and form two cells from one.
What is the significance of karyokinesis?There are many steps in cell division, two of which are important, the first is the division of the nucleus, known as karyokinesis, which is the process of nuclear division that includes replication of the genetic material and separation of the duplicated chromosomes and is important for the production of genetically identical daughter cells for growth and repair in multicellular organisms. The single cell is divided into two cells after cytokinesis, which occurs at the end of cell division.
Hence, cell division occurs in two stages: the division of the nucleus, called karyokinesis, and the division of the cytoplasm, called cytokinesis, and both of these include cell division and form two cells from one.
