if something is burned a reaction has occurred
Answer:
true
Explanation:
When the reactants are heated, the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more 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

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.
does the sand at night have less kinetic energy than the sand on a sunny day?
Explain the difference between how light falls on the Earth near the Equator or the Poles
Answer:
Explanation:
The normal amount of solar radiation reduces from the Equator to the poles. This is because the low latitudes (near the Equator deliver relatively large amounts of radiation all year, and at high latitudes (near the poles), the more slanting angle of the Sun’s rays together with long periods of darkness in the winter, result in a low amount of received radiation.
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.

Flagellants atoning for sinsGovernments quarantining all those who fell illShutting down tradePrayingWhat is a plague?A plague is a highly infectious and often fatal disease caused by the bacterium Yersinia pestis. The most infamous outbreak of the plague occurred in the 14th century in Europe, killing an estimated 25 million people, or one-third of the population. The disease is typically spread through the bite of an infected flea, although it can also be transmitted through contact with infected animals or humans.
There are three forms of the plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and causes swollen lymph nodes, fever, chills, and fatigue. Septicemic plague affects the bloodstream and can cause fever, chills, abdominal pain, and vomiting. Pneumonic plague affects the lungs and can cause fever, cough, chest pain, and difficulty breathing.
Today, the plague is rare but still exists in some parts of the world, including Africa and Asia. Early diagnosis and treatment with antibiotics are essential for successful treatment of the disease.

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.

The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.
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)

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.

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?

Which of the following is supported by the data?
A
Female sea turtles develop at higher temperatures.
(Choice B)
B
The sex of sea turtle offspring depends on the incubation temperature.
(Choice C)
C
The largest number of male sea turtles will develop at 28
(Choice D)
D
Most of the sea turtle eggs hatched if incubated at 26
Answer:
Choice B i had this question a long time ago ;)
Explanation:
Answer:
The sex of sea turtle offspring depends on the incubation temperature.
Explanation:
1.) In low incubation temperatures (26°C) and high incubation temperatures (36°C), a large number of sea turtle embryos die.
2.) In temperatures 30°C and below, no males hatch, and in temperatures 34°C and above, no females hatch. This suggests that the sex of the hatchlings is affected by incubation temperature.
3.) The correct answer is: The sex of sea turtle offspring depends on the incubation temperature.
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.
