Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

How many neutrons does hydrogen-1 have? How many neutrons does hydrogen-2 have?
Answer:
One Neutron
Explanation:
All three forms have one proton (pink) and one electron (dark green) but differ in the number of neutrons (gray) in the nucleus. Protium, or ordinary hydrogen (top), has no neutrons. Deuterium, or hydrogen-2 (bottom left) has one neutron. Tritium, or hydrogen-3 (bottom right) has two neutrons.
distinguish between coral reefs and kelp forests
Coral reefs and kelp forests are both underwater ecosystems, but they are quite different from each other. Coral reefs are made up of tiny animals called coral polyps that secrete calcium carbonate skeletons, which build up over time to form the reef structure. Coral reefs are found in warm, clear, shallow waters in tropical and subtropical regions.
Kelp forests, on the other hand, are underwater forests made up of large, brown seaweeds called kelp. Kelp forests are found in cold, nutrient-rich waters in temperate regions. Kelp forests provide habitat for a wide variety of marine life, including sea otters, fish, and invertebrates.
Overall, coral reefs are characterized by their hard, rock-like structure and the diversity of colorful marine life they support, while kelp forests are characterized by their tall, swaying seaweed and the abundance of fish and other animals they attract.

Which measurements could create more than one triangle?
A. Sides measuring 3 cm, 8 cm, and 15 cm
B. Sides measuring 10 cm and 20 cm and an included angle
measuring 50°
C. Angles measuring 100°, 10°, and 70°
D. Angles measuring 110°, 40°, and 40°
SUBMIT
The measurements that could create more than one triangle are options C and option D.
Explanation: For a triangle to exist, the sum of any two sides of a triangle must be greater than the length of the third side.
In option C, the angles measuring 100°, 10°, and 70° do not satisfy this condition, as the sum of the angles 10° and 70° is less than 100°, making it impossible to form a triangle. However, by rearranging the angles, such as 10°, 70°, and 100°, we can create a valid triangle.
In option D, the angles measuring 110°, 40°, and 40° also violate the condition for a triangle, as the sum of the angles 40° and 40° is less than 110°. However, by rearranging the angles, such as 40°, 40°, and 110°, we can create a valid triangle.

Select the correct statement Question 65 options: 1) GPP is the energy spent staying alive 2) GPP is the energy used in cellular respiration 3) GPP is part of NPP 4) NPP is the energy used in growth and reproduction
Answer:
1) GPP is the energy spent staying alive
Explanation:
Gross primary productivity is the energy that is spent by the organism to staying alive because energy is required by the organism for doing activities that is necessary for the survival. Gross primary productivity refers as the rate at which solar energy is captured in sugar molecules during the process of photosynthesis. Producers such as plants use some of this energy for metabolism and cellular respiration as well as some for growth and building tissues.

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. The expected percentages of progeny phenotypes are tall oval = 41%, short round = 41%, tall round = 9%, and short oval = 9%.To determine the proportion of progeny expected to be tall and produce round fruit, we need to consider the alleles for each trait. Allele D produces tall plants (dominant) and allele d produces short plants (recessive). Allele R produces round fruit (dominant) and allele r produces oval fruit (recessive).From the given percentages, we can deduce that tall ovals and short ovals combined make up 9%. Since tall oval is 41% and short oval is 9%, the proportion of progeny expected to be tall and produce round fruit is 41% - 9% = 32%.Therefore, the proportion of progeny expected to be tall and produce round fruit is 32%.For more questions on diploid plant

Which carbon reservoir has the longest residence time? (1 point)
plant biomass
Oceans
soil
fossil deposits
The carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.
What is a carbon reservoir?A carbon reservoir may be defined as being stored form of carbon in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
The movements of carbon take place through the four major reservoirs of the earth. It includes the biosphere, lithosphere, hydrosphere, and atmosphere. Plant biomass holds carbon for a very less period of time followed by soil. But the deposits of fossils hold the concentration of carbon for a maximum period of time.
Therefore, the carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.

Answer:
5 body system
Explanation:
The aroma from the cookies get in into the nostril with oxygen through respiration system.This diffuses through the nostril to the olfactory lobe.
Endocrine system stimulates the production saliva from the salivary glands into the mouth.This is salivation.
Running to the kitchen and picking one involved the activity of skeletal and muscular systems systems through contraction of muscles and supports by the bones
The olfactory lobe is in the olfactory system of the nervous system,This is transfer to the brain -to the olfactory cortex for analysis.
When the food is eaten,the taste sensation is sent to the orbital cortex for the blend of taste and aroma of the cookies to give a pleasant flavour.
Likewise the digestion of cookies begin in the mouth,while that of the milk starts in the stomach.This is digestive system

ecosystems
symbiosis
competition
The remora fish, which adheres to a shark and feeds on the leftovers of the Parasitism, mutualism, and commensalism are all types of symbiosis. The correct option is C.
Thus, a biological relationship between two or more distinct species is called symbiosis. Three different kinds of symbiotic interactions include parasitism, mutualism, and commensalism. One species gains from parasitism while the other suffers. The parasite can harm or even kill its host while feeding on it. In a mutualistic connection, both species gain from the interaction.
For instance, bees pollinate flowers while the blooms feed the bees nectar. One species gains by commensalism, whereas the other is neither aided nor hurt, which is a type of symbiosis.
Thus, the ideal selection is option C.
