In what ways does carbon enter the hydrosphere?
Answer: When oxygen is present, aerobic respiration occurs, which releases carbon dioxide into the surrounding air or water. Otherwise, anaerobic respiration occurs and releases methane into the surrounding environment, which eventually makes its way into the atmosphere or hydrosphere.

Match the biochemical action with the appropriate hormone: 1) increase in glucose uptake A) glucagon 2) increase in gluconeogenesis B) insulin 3) increase in cAMP levels (muscle) C) epinephrine 4) decrease in lipolysis 5) decrease in glycolysis 6) increase in ketogenesis
Answer:
1) B) insulin
2) A) glucagon
3) C) epinephrine
4) B) insulin
5) A) glucagon
6) A) glucagon
Explanation:
High levels of glucose in the blood promote the release of insulin hormone which functions to stimulate uptake and utilization of glucose by cells. Insulin may also act to inhibit lipolysis in adipocytes and stimulates triglyceride storage. Glucagon hormone controls blood sugar (glucose) by stimulating glycogenolysis (conversion of glycogen to glucose), promoting gluconeogenesis (glucose synthesis), and inhibiting glycolysis (glucose breakdown). Moreover, glucagon also can increase ketogenesis (i.e., the production of ketone bodies by breakdown of fatty acids and ketogenic amino acids) when insulin is inhibited. Finally, epinephrine hormone binds to receptors localized on the surface of muscle cells, which stimulate the production of cyclic-AMP (cAMP), a second messenger (i.e., a signaling molecule).

According to the Law of Conservation of Matter, if the reactants of photosynthesis have 18 oxygen atoms, how many oxygen atoms will be in the products that are produced?
Answer:
18
Explanation:
all the law is saying is that matter cant be created nor destroyed, so if 18 oxygen atoms are used, there will be 18 oxygen atoms in the end, no matter what, doesn't matter what they use it for or what

3. Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?
Answer:
See below
Explanation:
Active transport is the movement of materials across a membrane that requires an input of energy from a cell. This is because ions move into and out of cells and because cells contain proteins that do not move across the membrane and are mostly negatively charged, there is also an electrical gradient, a difference of charge, across the plasma membrane. the interior of living cells is electrically negative with respect to the extracellular fluid in which they are bathed.
At the same time, cells have higher concentrations of potassium (K+) and lower concentrations of sodium (Na+) than does the extracellular fluid. In a living cell, the concentration gradient of Na+ tends to drive it into the cell, and the electrical gradient of Na+ (a positive ion) also tends to drive it inward to the negatively-charged interior. The situation is more complex, however, for other elements such as potassium.
To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from adenosine triphosphate (ATP) generated through the cell’s metabolism. Active transport mechanisms, collectively called pumps, work against electrochemical gradients. Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.

NATURAL SELECTION is defined as, individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits.
a. True
b. False
The correct answer is true.
It is true that natural selection is defined as individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits.
Based on the concepts developed by scientists Charles Darwin, natural selection is the way species and all living organisms on planet earth transform and adapt to the environmental conditions where they live.
Charles Darwin did deep research in South America and some islands in the region and researched fossils, animals, and vegetation.
In 1869, he published his interesting results in a book called "On the Origin of Species."
Answer:
True
Explanation:
I took a test with the same question and i put true and i got it right.

Which organisms have many cells that are grouped together into tissues?
A Prokaryotic
B Unicellular
C Bacterial
D Multicellular
Answer: A
Explanation:These organisms are made of prokaryotic cells — the smallest, simplest and most ancient cells. Organisms in the Eukarya domain are made of the more complex eukaryotic cells. These organisms, called eukaryotes, can be unicellular or multicellular and include animals, plants, fungi and protists

Which phrase best describes the process of crossing over?
A: Pairs of homologous chromosomes exchange segments.
B: Pairs of sister chromatids exchange segments.
C: Pairs of homologous chromosomes become linked.
D: Pairs of sister chromatids become linked.
Answer:
A
Explanation:
Pairs of homologous chromosomes exchange segments is the phrase that best describes the process of crossing over.
The process of crossing over is the exchange of genetic material specifically of a DNA segment that happens between two pairing chromosomes, that is, they exchange sections of their DNA.
Homologous chromosomes unite in pairs and exchange their genetic information during the germ line.It is very important since it is a phenomenon that contributes to genetic variation, natural selection and adaptation to environmental changes.Therefore, we can conclude that pairs of homologous chromosomes exchange segments of their DNA is the phrase that best describes the process of crossing over.
