Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.

Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling

Explain how a change in the sequence of nucleotides in a strand of DNA might cause a protein to malfunction
Answer:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction.
Explanation:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction. If insulin does not work correctly, it may not be able to bind to the insulin receptor.

how does renewable energy affect non-human organisms? (plants, animals, bacteria, fungi,etc.)
Answer:
Non Renewable Energy Impact on Environment
All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

If there is moisture in the atmosphere as the front (pictured) comes through, what effect could it have on temperature and weather?
(ANSWER FAST!!)
Answer:
c)The temperature would decrease and there would be a chance of thunderstorms.
Explanation:
The temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.
What is Thunderstorm?A thunderstorm is defined as a storm with lightning and thunder produced by a cumulonimbus cloud, usually producing strong winds, heavy rain, and sometimes hail. Thunderstorms are so called because of the thunderous loud noise they make.
There are three basic elements that lead to the development of thunderstorms: moisture, an unstable atmosphere, and some way for the atmosphere to move where the moisture is necessary to produce thunderstorm clouds and precipitation.
Thus, the temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

What cellular process is occurring in the organelle labeled A?
(5 Points)
Students constructed a diagram to represent two related cellular processes.
F. Photosynthesis
G. Cellular respiration
H. DNA replication
J. Protein synthesis
Answer:
F. Photosynthesis
Explanation:
The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.
The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.
What is Photosynthesis?
Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.
The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.
Therefore, the correct option is F.

how does water potential affect molarity or how is molarity and water potential related
Answer:
If the solute concentration of a solution increases, the potential for the water in that solution to undergo osmosis decreases. Therefore, the more solute that is added to a solution, the more negative its osmotic (solute) potential gets.

what is a membrane potential and how is it generated?
Answer:
Differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Typical values of membrane potential are in the range –40 mV to –70 mV. ... These concentration gradients provide the potential energy to drive the formation of the membrane potential.

Why is blood a slightly higher temperature than typical body temperature?
O As bacteria and viruses are destroyed by leukocytes, they release bursts of heat

The excess mitochondria in red blood cells produce extra ATP

1. In passive transport, what direction do molecules move?
2. In active transport, what direction do molecules move?
Answer:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.
Explanation:
The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.
The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

What may happen if mitosis doesn't start around the open wound?
Mitosis is the type of cell division where the daughter cells are exact copies of the parent cell. Mitosis takes place around the open wound area for recovery but if mitosis does not start around the open wound recovery would not take place.
What is Mitosis?
Mitosis is the process of cell division where the parent cell undergoes division to form daughter cells which are exact copies of the parent cell. Mitosis is also known as Equational division. The chromosomal number in the parent cell is exactly same as the daughter cells.
Mitosis is divided into two phases: Interphase and M-phase. The actual cell division takes place in the M-phase. M-phase is divided into four phases which are Prophase, Metaphase, Anaphase, and Telophase. In mitosis, one parent cell gives rise to two daughter cells. Mitosis takes place in all the cells of an organism.
Mitosis is responsible for restoring the cell number back to normal in body.
