Is it a scientific theory or a scientific law that the characteristics of living things change over time?
Answer:
Scientific Theory
Explanation:
The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.
In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.
Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

What are possible products of glycolytic, or anaerobic, catabolism?
Answer:
The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.
Explanation:
Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.
Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.
Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.
This hormone has the opposite effect to glucagon.

The correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.
Based on the given information, neither hypothesis A nor hypothesis D is supported by the data. Hypothesis A suggests that manatees, an abiotic factor (which is incorrect, as manatees are living organisms), experienced a decline in their population due to propeller boats, a biotic factor.
Hypothesis D suggests the opposite, that manatees (an abiotic factor) experienced an increase in their population due to propeller boats (a biotic factor).
Hypothesis B, on the other hand, is supported by the data. It states that manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.
This hypothesis aligns with the information provided, as the graph for manatee population shows a decrease over the same 20-year period in which the number of propeller boats increased.
Therefore, the correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

(2018). halide-directed synthesis of square prismatic ag nanocrystals by the polyol method. chemistry of materials. (doi
A critical challenge in the fabrication of bottom-up plasmonic materials is achieving shape control of high-quality metal nanocrystals.
Using a modified polyol method, we create a unique anisotropic Ag nanocrystal shape. The controlled addition of Br- anions during the nucleation and growth process results in single-crystalline Ag square prism nanocrystals with two square facets and four rectangular facets, uniform size distributions, and a high yield (96%).
Br- acts as a reshaping agent in the formation of single-crystalline seed nanoparticles, which then direct anisotropic growth in the 100 direction. Optical absorption spectroscopy, which reveals the localized surface plasmon resonances of the square prisms, is used to monitor nanocrystal growth and shape development.
Electrodynamic simulations show that the high aspect ratio shape causes strong near-field enhancement, implying that these nanocrystals could be used as optical nanoantenna in plasmonic platforms such as surface-enhanced Raman spectroscopy sensors and optoelectronic junctions.

Where do I find spinal tracks going to the brain? (Posterior or Anterior)?
Answer:
Posterior
Explanation:
Posterior refers to the back or rear part of something, while anterior refers to the front part of something.
In the context of the human body, the posterior part is the back side of the body, while the anterior part is the front side of the body. For example, the back of the head is the posterior part of the head, while the front of the head is the anterior part of the head.
Similarly, in the context of the spinal cord, the posterior part is the back part of the cord, while the anterior part is the front part of the cord. The posterior part of the spinal cord contains the spinal tracks that carry sensory information from the body to the brain, while the anterior part of the spinal cord contains motor neurons that control the movement of muscles.
Overall, the terms posterior and anterior are used to describe the relative positions of different parts of the body, with posterior referring to the back part and anterior referring to the front part.
Spinal tracks that go to the brain are located in the posterior part of the spinal cord. The spinal cord is a long, narrow structure that extends from the base of the brain down to the lower back. It is made up of a bundle of nerve fibers that carry signals between the brain and the rest of the body.
The spinal tracks that go to the brain are located in the posterior part of the spinal cord, which is the back part of the cord. These tracks are used to carry sensory information from the body to the brain, as well as motor signals from the brain to the body. The spinal tracks in the posterior part of the spinal cord are organized into different levels, each of which carries signals to and from specific parts of the body.
In contrast, the anterior part of the spinal cord is located at the front of the cord and contains motor neurons that control the movement of muscles. The anterior part of the spinal cord is not directly involved in carrying sensory information to the brain.
Overall, the spinal tracks that go to the brain are located in the posterior part of the spinal cord, not the anterior part.
At any given time, a 4-acre field contains an average of 200 kg dry weight of mallow plants. For these calculations, assume that the food chain shown below is isolated and that there are no other predators or sources of food involved. mallow plant- painted lady butterfly - phoebe- fox Assume that the dry weight of each animal is on average as indicated below Painted lady butterfly 0.1g Phoebe 48 Fox 1 kg (1000 g) a. Assuming that 10% of the biomass, as measured in dry weight, is transferred from one trophic level to the next higher level, calculate how many foxes the field could support at any given time. Show your work and include in your calculations how many phoebes and painted lady butterflies the field could support b. Construct a biomass pyramid diagram depicting the food chain described above. Include only the organisms of the food chain that the 4-acre field will support, and label the trophic level occupied by each organism. The units in your pyramid should be grams per square meter (g/m?) (Note: 1 acre = 4046.86 m).
a. The 4-acre field will support a total of 200 g foxes at any given time.
b. The pyramid is attached.
How to calculate support for food chain?a. To calculate the number of foxes that the field could support at any given time, we need to work our way up the food chain, starting with the mallow plants:
200 kg of mallow plants x 10% = 20 kg available to painted lady butterflies
20 kg of painted lady butterflies x 10% = 2 kg available to phoebes
2 kg of phoebes x 10% = 0.2 kg available to foxes
Now to convert kg to g to make the calculations easier:
200 kg = 200,000 g of mallow plants
0.1 g per painted lady butterfly x 20 kg of painted lady butterflies = 2000 g = 2 kg
48 g per phoebe x 2 kg of phoebes = 96,000 g = 96 kg
1000 g per fox x 0.2 kg of foxes = 200 g
Therefore, the 4-acre field could support approximately 200 g of foxes at any given time.
b. The biomass pyramid diagram is attached below.
To convert from kg per acre to g per square meter, multiply by a factor of 24.711 (since there are approximately 4046.86 square meters in an acre).
