A population of a certain kind of fish is introduced into a new habitat. These fish have variations in color from light to dark. Because of the lighting conditions and predators in this new habitat, light colored fish survive better near the surface and dark-colored fish survive better near the bottom. What change would likely result after many generations of these fish living in this environment
Answer:
There would be two populations of fish:
Light-colored fishes near the surface
Dark-colored fishes near the bottom.
Explanation:
After many generations, there would be two populations of fish: Light-colored fishes near the surface and Dark-colored fishes near the bottom as light-colored fish survive better near the surface and dark-colored fish survive better near the bottom due to the lighting conditions and predators in the new habitat.

Answer:
The correct answer is:
planters (D)
Explanation:
The key statement in the question is that Andrew wants to apply pesticides and fertilizers to all his crops across his large land. The most effective way of doing this is by using a planter to apply both the fertilizer and the pesticide as the planting occurs. This will ensure that the fertilizers and pesticides are applied directly to the crops and not scattered on the vast land.

Identify the neurons described below.
are activated in the brain and spinal cord in order to send messages in response to the stimuli of touching the sharp object
cause you to pull your hand away from the sharp object
are activated first when you touch a sharp object
Answer:
The correct answer is:
1. interneurons, 2. motor neurons, and 3. sensory neurons.
Explanation:
There are three types of neurons that help in providing information of the external environment or stimuli to the brain and have an appropriate response according the stimuli. These three neurons are; sensory neurons, motor neurons, and interneurons.
Sensory neurons are the neurons that carry the signal or information of the stimulus which is activated first when you touch a sharp object, Interneurons are the neurons that are present in the brain and spinal cord when activated to send messages in response to the stimuli of touching the sharp object, motor neurons are the neurons is carry the response signals from the brain and spinal cord to the muscle as it cause you to pull your hand away from the sharp object
Answer:
1. Interneurons 2. motor neurons 3. sensory neurons
Explanation:
This is the correct order for this question on the edge assignment. Before you b*tch about it being wrong, please check and make sure you aren't on the question before this which has a the same answer choices in a different order.
What effect does the transfer of matter and energy have on organism and their
environment?
Answer:
In many environments, energy enters as daylight and is changed by makers into an organically usable type of issue through photosynthesis. That matter and energy at that point passes from one organic entity to another through food networks. Some energy is delivered from the framework as warmth.

explain why biodiversity in an ecosystem is important?
Answer:
It is important because we need many different types of animals. Food chains are made up of many different links, and if there are fewer links, this will lead to animals not being able to feed. Biodiversity boosts the ecosystem and leads to an ecosystem that is self sustaining and able to produce things for people.
Explanation:
The Richter scale ranges from 1 to 10 in increments of tenths and measures the amount of energy released by an earthquake, not the amount of damage or the effect on people.

Which of the following is involved in the opening of stomata for the gas exchange of the plant?
Answer: Osmotic Pressure, lb/in2
Explanation:
Osmotic pressure is involved in the opening of stomata for the gas exchange of the plant.
What are stomata?In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Transpiration and gas exchange is made possible by stomata. It is surrounded by two guard cells that regulate how the stomata open and close. Stomata open during the day for gaseous exchange and to release water vapour during transpiration. The stomata open and close in response to changes in the turgor pressure within the guard cell.
Hence, osmotic pressure is responsible for the opening and closing of stomata.

How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)
Answer:
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.

1. Give 2 similarities between each of the skulls that might lead to the conclusion that these are all related.
2. What is the biggest change in skull anatomy that occurred from the dawn horse to the modern horse
Complete question:
You will find the image of the skulls in the attached files.
Answer:
1) 2 similarities between each of the skulls might be the presence of the nasal spine, and the interdental space.
2) The size of the skull seems to be the most noticeable change in skull anatomy between the dawn horse and the modern horse.
Explanation:
Each of the nasal bones in horses ends in a protuberance named "the nasal spine". These spines converge in the distal portion of the bone. These spines and the incisive bone delimitates the space called the naso-incisor notch. In the attached figure you will see the nasal bone in red and the nasal spines. This structure is present in all the skulls in the same position. The interdental space is the space left between the front teeth and the back teeth. It is useful to recognize a male from a female in modern horses. This space can be found in all the skulls. You will see it in blue in the image.The biggest change in skulls between the dawn horse and the modern horse is the size. The skull keeps the original shape or very similar shape but varies in length and height.
The two (2) similarities between each of the skulls that shows that they are all related include:
They all have a similar ridge that typically protrudes from the top.Each of the skulls have a set of flattened teeth.What is an evolution?Evolution can be defined as a process of gradual change in the characteristics and genetic make-up of the species of a living organism over several generations.
In Genetics, a scientific technique which is commonly used to determine evolutionary relationships between organisms is the study of their fossils and biochemical similarity.
The similarities between each of the skulls.Thus, the similarities between each of the skulls that shows that they are all related include:
They all have a similar ridge that typically protrudes from the top.Each of the skulls have a set of flattened teeth.All the skulls have the same overall shape.Additionally, the biggest change in skull anatomy with respect to the dawn horse and modern horse is that the modern horse has a larger skull.

How does the carbon cycle support the Law of Conservation of Mass?
The carbon cycle supports the Law of Conservation of Mass, as the law states, the carbon also reuse and reabsorb in the carbon cycle.
What is the carbon cycle?
The carbon cycle is the movement of carbon from the atmosphere to plants and organisms. Carbon is coal when burned turn into gas.
The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things.
According to the Law of Conservation of Matter, matter can be created or destruct. Because the carbon cycle recycles the same carbon atoms, it serves as an illustration of the Law. Some carbon is stored for future growth, and some are used for energy.
Thus, because carbon is reused and reabsorbed in the carbon cycle, the Law of Conservation of Mass is supported by this law.

The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
