Explanation:
the energy required to lift an object is supplied by ATP, which is made by breaking down molecules of
a. carbon dioxide
b. oxygen
c. glycolysis
d. glucose
The energy provided by ATP is driven by the breakdown of glucose molecules. Thus, option D is correct.
ATP or Adenosine triphosphate is the energy molecule that is able to provide energy to the body. Varying pathways and cycles in the cell produce ATP.
Which molecules produce ATP?ATP production is carried out in the degradation of the complex molecules by the cell. The cycle is operated primarily in the cell for the production of ATP in glycolysis.
The ATP is produced in the glycolysis cycle with the breakdown of glucose molecules. Thus, option D is correct.

A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.
What issue might be present in the soil if the ration to Nitrogen (N), Phosphate (P)
and Potassium (K) are sufficient, but the leaves of a
plant are showing phosphate and potassium deficiency?
Answer:
Low level of nitrogen in the soil.
Adding organic materials poor in mineral nitrogen to the soil, which encourages the subsistence of soil microorganisms on mineral nitrogen to break down these materials, and this causes a temporary reduction in the proportion of mineral nitrogen in the soil.
Soil drought.
Problems with root growth due to soil compression or disease.

Explanation:
name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule
Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.
Transcription is the process that occurs in the nucleus.
What is the process that synthesizes the mRNA?mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.Therefore, transcription results in the formation of the mRNA.

Which two characteristics describe organisms in the kingdom Animalia?
A. They are heterotrophic
B.They are unicellular
C. They are multicellular
D.They have prokaryotic cells
This is a multi (two) answer
Answer:A and C
Explanation:
Answer:
A and C
Explanation:
All members of Animalia are multicellular, and all are heterotrophs (that is, they rely directly or indirectly on other organisms for their nourishment). Most ingest food and digest it in an internal cavity. Animal cells lack the rigid cell walls that characterize plant cells.
I also did the test and got it right.
how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.

Answer:
The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.
Explanation:
Mutation Classes
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - CFTR is made in smaller than normal quantities
What characteristic have helped humans survive major changes in the environment? the ability to adapt to new conditions the ability to outsmart predators the ability to run the ability to write and speak language
Answer:
Characteristics that have helped humans survive major changes in the environment are their brains and body. Human's social cooperation with tool making always increases.
Survival of the fittest explains the mechanism of natural selection. The ability to adapt to new changes has helped humans survive major changes in the environment.
What is adaptation?Adaptation is the ecological process that is the process of the adjustment of the structures, behaviors, and physiology of the organism to suit the altered environment.
It is the variation that increases the fitness of the organism so that it can survive and reproduce in a specific environment. It is a dynamic evolutionary method, that is essential for the sustainability of the organisms.
