Explanation:
a hormone that can lower blood levels of calcium ion is
Answer: Calcitonin
Explanation:
When calcium levels in the blood is low, Parathyroid hormone is released to increase it. On the other hand, when calcium levels are high and need to be decreased, Calcitonin is secreted.
Calcitonin acts in opposition to PTH by inhibiting osteoclasts (a cell from which bone develops), stimulating osteoblasts, and increasing the excretion of calcium into the urine by the kidneys. [lumencandela]

A family wants to adopt a dog that has very thick fur and cannot be exposed to temperatures above 90 degrees Fahrenheit. This family should only adopt this dog if they live in an area that has which climate properties?
A High average temperatures
B High average rainfall
C Low average rainfall
D Low average temperatures
Answer:
low average temperatures
Explanation:
low average temperatures so the dog doesn't overheat
Answer:
The answer should be D.
Explanation:
A doesn't work - because the dog cannot be exposed to high temps.
B doesn't work - regardless of rain or not, there's always humidity.
C doesn't work either (see B's explanation)
D seems to be the only correct answer.

During fertilization in Choose... two fertilization events take place. One fertilization produces the choose... . Another fertilization event produces the Choose... that nourishes the seedling as it grows.
Answer:
angiosperms
Zygote
Endosperm
Explanation:
During fertilization in angiosperm, two fertilization events take place. One fertilization produces the zygote another fertilization event produces the endosperm that nourishes the seedling as it grows.
What is the fertilization process in angiosperms?Angiosperms are characterized by a double fertilization event in which one fertilization produces the zygote and the other produces tissue, called endosperm, within the seed.
After double fertilization, a post-fertilization event occurs, that specify triple fusion, the PEN (primary endosperm nucleus) then grows into the endosperm.
Therefore, in this event, one sperm fuses with the egg to form the 2n zygote, and the other sperm fertilizes with two polar nuclei to create the 3n endosperm is known as double fertilization.

the most significant difference between biofuels and fossil fuels is that biofuels are:
The most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass, that is, they are processed energy resources that come from organic compounds extracted from wild or cultivated plants.
Fossil fuels (such as oil, coal, and natural gas) are those that come from the natural decomposition of organic matter.
They are called non-renewable energies because they are limited natural resources since they require an extensive period of time and specific conditions to form.
On the other hand, a biofuel is a term that is used to refer to all those fuels produced from biomass, that is, through the chemical or physical treatment of organic or plant waste.
That is, unlike fossil fuels that come from energy stored for long periods in fossil remains, biofuels come from biomass, or organic matter that constitutes all living beings on the planet.
Biomass is a renewable energy source, as its production is much faster than the formation of fossil fuels.The use of biofuels as a renewable energy source can help reduce the consumption of fossil fuels, responsible for the generation of greenhouse gas emissions.During its production, part of the carbon dioxide that could be released into the atmosphere is extracted from the biomass.
For this reason, biofuels do not contribute to the emission of greenhouse gases.
Therefore, we can conclude that the most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass.

A. ( answer)
Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
Explanation:
DNA replication involves several different enzymes. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of the DNA molecule. Then an enzyme called DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. Lastly, the DNA polymerase "proofreads" each new strand to make sure that each DNA molecule is perfect, or a nearly perfect copy of the original molecule.

why does your body release a little bit of energy with each step rather than all at once?
In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.
How glucose used in cellular respiration?During the process of aerobic cellular respiration, glucose reacts with the oxygen which leads to form ATP ( Adenosine triphosphate) that has to be used by the cell. Carbon dioxide and water has been created as the byproducts. The overall equation for the process of aerobic cellular respiration is that during cellular respiration, glucose and oxygen react in order to form ATP ( Adenosine triphosphate).
Adenosine triphosphate has known as an organic compound which provide energy to living organisms to drive many operations in living cells such as contraction of molecule, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
The energy consumed by the animals in the form of glucose has been conserved because it is transformed into the chemical energy as the carbon dioxide has been produced during the respiration.
Therefore, In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.
