What elements are needed to carry out photosynthesis? Select all that apply.
water
solar energy
oxygen
carbon dioxide
glucose
carbohydrates
Answer:
Water, Solar energy, and Carbon Dioxide.
Explanation:
The overalll reaction of photosynthesis is 6CO2 + 6 H2O -> C6H12O6 (Glucose) + 6O2. This reaction is driven by energy in the form of electromagnetic radiation (light).
As we can see we need CO2, H2O, and light as reactants. And oxygen + glucose (carbohydrates) are our products.

The mechanism of stabilizing the gfr based on the tendency of smooth muscle to contract when stretched is known as __________.
Answer: Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR. Hydrostatic pressure in the Bowman's capsule will work to decrease GFR

You determine that a victim is unresponsive but breathing. While waiting with the victim for EMS personnel, you would position the victim:_______.
Answer:
You would put the victim in the recovery position
Explanation:
The recovery position is a position in which the victim is laying on their side.
You determine that a victim is unresponsive but breathing. While waiting with the victim for EMS personnel, you would position the victim in the recovery position.
They benefit from having their head in this posture with their airway open. Their tongue will slip forward, allowing blood and vomit to pour out. It is referred to as the "recovery position" at times.
The recovery posture will keep someone's airway open and clean. It also makes sure that they won't choke on any liquids or vomit.

True or false? the driving force for the unloading of oxygen from hemoglobin into tissues is the difference in pco2 levels between the blood and body tissues.
Answer:
False. The driving for is the partial pressure gradient of O2 (PO2 difference), not the PCO2 gradient.
However, keep in mind that an increase in PCO2 can facilitate the unbinding of oxygen from hemoglobin. This is due to a decrease in pH associated with PCO2 increase. The H+ ions bind to hemoglobin and decrease it's affinity for oxygen, this is called the bohr effect. But the PCO2 is not the main driving force of oxygen unbinding.
What changes must humans make to protect the environment
Answer:
According to climate experts, it is urgent to fight the growth of the greenhouse effect, which, by contributing to the excessive warming of the planet, threatens its ecological balance. From the reduction of fossil fuel consumption to the geological storage of CO2, many solutions are envisaged to preserve a balance threatened by increasing industrialization and the development of transport.
Reducing CO2 emissions requires simultaneous action on several fronts: controlling energy demand, improving energy efficiency during production and conversion of fossil fuels, replacing fossil fuels with energy containing less or carbon and the establishment of a market for tradable CO2 emissions permits.
A new way to fight greenhouse gases is the capture of these gases from its source of production and its storage in the underground, appears as a promising solution to face the risk of climate change. Major scientific breakthroughs are expected in this area.

In eukaryotic cells, if you compared the DNA sequence of a gene with the sequence of the processedmRNA that was transcribed from the gene you would find
The DNA sequence of a gene differs from the sequence of the processed mRNA that was transcribed from the gene as it is longer and contains thymine instead of uracil.
What are processed mRNA?Processed mRNA refers to RNA they has been transcribed from a the DNA sequence of a gene.
A processed mRNA has the following differences from the DNA sequence of a gene:
It is relatively shorter It replaces thymidylate with uridylateTherefore, when comparing the DNA sequence of a gene with the sequence of the processed mRNA that was transcribed from the gene, it is longer and contains thymine in place of uracil.

Why is it that mutations to
body cells do not affect offspring?
Answer:
Since all cells in our body contain DNA
Explanation:
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations occur in non-reproductive cells and won’t be passed onto offspring. Its seeds will not carry the mutation. Somatic cells give rise to all non-germline tissues. Mutations in somatic cells are called somatic mutations. Because they do not occur in cells that give rise to gametes, the mutation is not passed along to the next generation by s means.

What is different about the way molecules move in gases?
Answer: Below
Explanation:
The states of matter are related to the speed of molecules. Slow molecules become solid because there are less energy/heat in them, therefore less speed. Since they have less energy in them, the molecules are more bunched up. The term absolute zero is when molecules are at a complete stop. Solids are slow, therefore condensed. Liquids are medium, and can flow, while gases are fast and disperse fairly easily.
