Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.
b) How does the thermal energy of solid water change as it melts?
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

Explanation:
Name and describe the five types of active transport systems.
Answer:
Please Mark as Brainliest. Please!!!!!!!!!!
Explanation:
Definition
Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.
Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine triphosphate (ATP).
For example, one type of active transport channel in the cell membrane will bind to the molecule it is supposed to transport – such as a sodium ion – and hold onto it until a molecule of ATP comes along and binds to the protein. The energy stored in ATP then allows the channel to change shape, spitting the sodium ion out on the opposite side of the cell membrane. This type of active transport directly uses ATP and is called “primary” active transport.
Another type of active transport is “secondary” active transport. In this type of active transport, the protein pump does not use ATP itself, but the cell must utilize ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below.
Lastly, active transport can be accomplished through processes called endocytosis and exocytosis. In exocytosis, a cell moves something outside of itself in large quantities by wrapping it in a membrane called a vesicle and “spitting out” the vesicle. In endocytosis, a cell “eats” something by wrapping and re-forming its membrane around the substance or item.
Each type of active transport is explained in more detail below.
Types of Active Transport
Antiport Pumps
Antiport pumps as an example of active transport
Active transport by antiport pumps
Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks.
One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”
Symport Pumps
Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration.
In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient.
One example of a symport pump – that of the sodium-glucose transport protein – is discussed below under “Examples of Active Transport.”
Sympoter pump as an example of active transport
Active transport by symporter pumps
Endocytosis
In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis.

Which of the following is NOT a characteristic of all living things?
Ability to reproduce
Ability to move
O Growth and development
Homeostasis
Answer:
homeostatis
Explanation:
The answer should be homeostatis. Organisms can not do this.
Answer:
Ability to move
Explanation:
All organism species have the ability to reproduce, grow and develop, and maintain homeostasis (for example, sweating). Not all organisms can move, however. Cacti, for instance, are stiff and do not move on their own, yet are still alive.

What does lemon juice, snake venom and cyanide have in common?
Answer:
enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.

The warming of the atmosphere by the trapping of heat being radiated to space is called
a)condensation
b)evaporation
c)the greenhouse effect
d)radiation
Answer:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
how are proteins made in animals and humans
Answer:
Through protein synthesis of course...
Explanation:
DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.

Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
