D.) It releases energy by breaking down glucose
Explanation:
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose...in cellular respiration, oxygen is used to break down glucose releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store the chemical energy for future use. For the most part, the planets living systems are powered by this process. Photosynthesis happens in regions of a cell called chloroplast.

6. What is the relationship between an organism's DNA and protein specificity?
A. DNA becomes a specific part of the protein structure
B. DNA determines the ribosomal RNA sequence that becomes part of the protein structure
C. DNA determines which RNA molecules are incorporated into protein molecules.
D. DNA determines the amino acid sequence of each protein.
Answer:
The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).
Explanation:
Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.
The steps in which this occurs can be summarized as follows:
The sequence of nitrogenous bases of a DNA strand is transcribed into the mRNA, which will go into the cytoplasm. The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid. During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.According to this, the DNA determines the amino acids sequence that will be in a specific protein molecule.

Which factors contributed to the additions of the modern cell theory
Answer:
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are msotly the same, both structurally and chemically; and finally, that energy flow occurs within.
Explain the energy transformation that occurs when a person exercises.
Answer:
Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.
The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.
Thermal energy is defined as the energy present within an object because of the motion of its particles.
So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.
Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.
Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Which BEST describes how metabolism is regulated eukaryotes? A. Starting and stopping metabolic processes are voluntary actions. B. Metabolism increases when the surrounding environment is temperature regulated. Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition. Metabolic processes are the most highly regulated in bacteria.
Answer:
Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition.
Explanation:
Eukaryotic metabolic regulation refers to the mechanisms by which metabolic anabolic and catabolic pathways are modulated in eukaryotic organisms. Anabolic enzymes are involved in the biosynthesis of molecules, while catabolic enzymes are involved in degradative pathways. Thus, enzymes regulate metabolic pathways by catalyzing chemical reactions at their corresponding rates of reaction. Moreover, feedback inhibition refers to those mechanisms occurring when one enzyme is inhibited by the end product of the metabolic pathway, enabling cells to regulate these products.

differences in long distance signaling in plant and animal cells.
Answer:
difference is animals have evolve nervous systems to transmit information signal from one part of the body to another. Plants do not have nervous systems, they use electrical signals to transmit information.
Explanation:
looked it up on the internet
The difference in long-distance signaling in plant and animal cells is plants do not have a nervous system, whereas mammals have developed them to carry information signals from one region of the body to another.
What is long-distance signaling?Long-distance endocrine signaling involves the production of signals by specialized cells and the release of those signals into the bloodstream, where they are transported to target cells in far-flung regions of the body. Hormones are signals that are created in one area of the body and move through the bloodstream to distant locations.
Therefore, plants lack a nervous system, whereas mammals have one built to transmit information signals from one part of the body to another, which makes long-distance signaling different between plant and animal cells.

ants that become immune to ant insecticides and are therefore able to multiply are an example of: please choose the correct answer from the following choices, and then select the submit answer button. answer choices natural selection. interaction. mutations. epigenetics.
Natural selection is one of the evolutive forces. It can select beneficial alleles, which are the product of mutations, and fixate them in the population. Option A. Natural selection.
What is natural selection?
Natural selection is one of the evolutive forces. It acts by selecting beneficial alleles and increasing their frequency in the population.
It results from the interaction between phenotype and environment, which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude can be defined as the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Aptitude must be significant to the natural selection act in its favor.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.
Individuals exposed to new selective pressures need to adapt to survive. Under these environmental conditions, individuals suffer mutations that lead them to avoid them. Since these mutations are beneficial, they are selected by Natural Selection, fixated in the genotype, and transmitted to the following generations.
Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
In the proposed situation,
1) ants were exposed to insecticides.
2) probably many of them dies, but some of them mutated and managed to survive
3) since this mutation was benefitial, it was selected by natural selection.
4) ants carrying this mutation got to reproduce and the mutation spread in the population.
Selective agent: insecticide.Ants response: mutation that lead to survivalThe correct option is then A. Natural selection.

Explanation:
antidiuretic hormone is important in maintaining homeostasis in mammals. adh is released from the hypothalamus in response to high tissue osmolarity. in response to adh, the collecting duct and distal tubule in the kidney become more permeable
Plasma osmolarity, or the concentration of solutes in blood, is the primary factor influencing antidiuretic hormone release.
Osmoreceptor neurons, which sense osmolarity in the hypothalamus, then trigger the release of antidiuretic hormone from the neurons that sense osmolarity. Osmoreceptors do not activate and antidiuretic hormone secretion is reduced when plasma osmolarity falls below a certain threshold. Ever-vigilant osmoreceptors perceive an increase in osmolarity over the threshold as a stimulus to activate the neurons that release antidiuretic hormone. The concentrations of antidiuretic hormone climb sharply and linearly with rising plasma osmolarity, as seen in the figure below.
Antidiuretic hormone release and thirst have an intriguing similarity. Although most likely not the identical ones, both occurrences seem to be triggered by hypothalamic osmoreceptors.
