How can the arrangement of atoms help explain how the white phosphorus and red phosphorus can both be pure phosphorus substances?
Answer:Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate.
Explanation:
Chemical element phosphorus has the atomic number 15 and the letter P in its symbol. Phosphorus, a multivalent nonmetal belonging to the nitrogen group, is generally always found in the form of inorganic phosphate, which is phosphorus in its maximally oxidized state.
What is phosphorus?The mineral phosphorus, which is also available as a supplement, is naturally present in many foods. It serves the body in a multitude of capacities. It is a crucial component of cell membranes, bone, and teeth. It maintains a healthy range of blood pH and aids in the activation of enzymes.
All tissues and cells must have phosphorus for growth, maintenance, and repair as well as for the creation of DNA and RNA, the genetic building blocks. The balance and usage of other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc, depend on phosphorus as well.
Thus, Chemical element phosphorus has the atomic number 15.

Roundworms
Type of skeleton (ENdoskeleton, EXoskeleton, or None)
Type of appendages (Jointed, Not Jointed, or Absent)
Segmentation (Present or Absent)
Type of symmetry (Radial, Bilateral, or None)
Answer:
Think about it. Worms move with MUSCLES. So the first answer is None.
The appendage of a roundworm is not present.
How do you think worms turn and move? They are segmented. The symmetry of a worm is Bilateral.

1. What is the most important mutation that led to human life?
Answer:The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.
Explanation:
How does increasing plant biomass (amount of plants) affect atmospheric CO
Answer:
Since there are more plants more carbon dioxide is being removed because plants are carbon reservoirs.

FIND THE INDEPENDENT & DEPENDENT VARIABLE!
- the amount of iron in blood depends on the amount of red meat a person eats.
Answer:
The answer is:
Independent: red meat eaten by a person
Dependent: iron in the blood
Explanation:
A dependent variable has to depend on something else, so in order for a dependent variable to exist or happen, there has to be the independent variable. The independent variable is something that does not need anything else to happen for it to take place. It s independent. Such as, a mother cannot have a child without sperm. The mother have a child is dependent, where the sperm is independent.

An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same animal. How should the animal be categorized
Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.

All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.
Answer: The products are spermatozoa that each have a head, midpiece and tail.
Explanation:
The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.

Explanation:
Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains
why plant cells require sunlight to make organic compounds, according to Gibbs's theory of free energy?
O The photosynthetic reaction releases free energy to the surroundings.
O The photosynthetic reaction's free energy is in equilibrium.
The reactants of photosynthesis have less free energy than the products,
The change in free energy (AG) of the photosynthetic system is less than zero.
Answer:
I'm not sure if this is correct but I think it's C
Answer:
C ( I think)
Explanation:
If a chemical reaction requires an energy input rather than releasing energy, then the ∆G for that reaction will be a positive value. In this case, the products have more free energy than the reactants. Thus, we can think of the reactions’ products as energy-storing molecules. We call these chemical reactions endergonic reactions, and they are non-spontaneous. An endergonic reaction will not take place on its own without adding free energy.
Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis.
Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with
the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the
incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher
labeled the COt2 supply to the algae with 14C, and the H20 with 180.
Which of the following results is expected?
O More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red
light.
O More 180 is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red
light
O More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green
light.
O More 180 is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green
light

Shenya Jones, a 34-year-old female, arrives at the office with a swelling and a red pustule on her face. She states the problem started two days ago as a small pimple near her nose. It became irritated then became extremely swollen and painful overnight. This morning there was yellow drainage noted at the site and the swelling has increased. The area of drainage is approximately 1 cm in diameter. The upper lip, side of the face, and nose are all swollen. She rates the pain in her face as a 7 out of 10. The physician thinks the condition may be impetigo or methicillin-resistant Staphylococcus aureus (MRSA), a type of skin infection that is resistant to the common antibiotics used to treat it. A wound culture is obtained.
1. Considering the structures of the skin, what most likely was the cause of the original pimple on this patient's skin?
2. How could Shenya have prevented this skin infection?

true or false:
Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
