The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.

Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.

Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.

Hence, after many generations, puffins of species B and C will increase.

1) The cell body of the motor neuron is located in the ventral or anterior horn of the grey matter. From there, it extends to the motor unit. 2) Contraction refers to negative feedback in which the body reacts when facing a stimulus.

The spinal cord is mainly composed of grey matter and white matter. The second one covers the first one.

The grey matter transversal section is composed of posterior, lateral, and anterior horns, also known as dorsal, lateral, and ventral horns, respectively.

Each type of horn contains a type of neuron.

The motor neuron from the exposed example is located in the anterior or ventral gray horn.

This example refers to negative feedback because the neurotransmitter release causes a cascade effect that ends in muscle contraction, tending to suppress or counter the original stimuli.

Any change that might occur in the internal functioning will be countered by negative feedback to maintain homeostasis.

Negative feedback needs receptors, central control, and effectors.

The Establishment of biological research institutes is so important in Ethiopia because realizing its immense potential to exploit biotechnology and the life sciences requires the opening of many new R&D parks.

The establishment of numerous additional R&D parks is necessary in order for biotechnology and the life sciences to reach their full potential. Only by establishing several more R&D institutions can Ethiopia utilize its potential biological and genetic diversity as well as local knowledge of biological diversity.

Ethiopia is hampered in its efforts to establish biotechnology as a tool for the development of the country's economy since it has just five research centers, despite the capacity of the universities and colleges.

Answer:

NCDs share four major risk factors: tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets.

Explanation:

Dural sinues: This forms at the base of the three folds

Subdural space : This contains the serous fluid.

Subarachnoid space: This contains blood vessels and cerebrospinal fluid.

The Subarachnoid space is defined as the space that separates the brain from the skull. It is known to be fluid filled with the cerebrospinal fluid. This helps to provide cushion effects in case of injury or trauma to the head.

Dural sinues: These sinuses are located at the dura mater between the endosteal and meningeal layers of the dura mater. They contain venous blood that originates for the most part from the brain or cranial cavity.

Subdural space : This is a potential space that can be visible when the arachnoid mater is separated from the dura mater. It is filled with serious fluid that aids in lubrication.

The main phases of mitosis in order from start to finish are as follows:

Mitosis may be defined as a type of cell division through which a parental cell is successfully divided into two daughter cells. These daughter cells are genetically identical to the parental cells and generally diploid in nature.

Prophase is the longest phase of karyokinesis. In this phase, the nuclear membrane and nucleolus disappear. In metaphase, the chromosomes are usually lined up in one plane by attaching to the spindle through the centromere.

Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and chromosomes move to opposite poles. In telophase, the two sets of daughter chromosomes reached opposite poles and are converted into chromatin thread.

Therefore, the main phases of mitosis order from start to finish are well described above.

All cnidarians have two tissue layers. The outer layer is called the epidermis, whereas the inner layer is called the gastrodermis and lines the digestive cavity. Between these two layers is a non-living, jelly-like mesoglea

Cnidarias have an internal sac for digestion which is called the gastrovascular cavity. The gastrovascular cavity has only one opening, a mouth, through which the animal takes in food and releases waste. Tentacles radiate outward from the rim of the mouth.

The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis. The epidermis contains a collection of different types of cells. These include epitheliomuscular cells which contract and enable movement, interstitial cells that give rise to many other cell types such as egg and sperm, cnidocytes which are specialized cells unique to cnidarians which in some cnidarians contain stinging structures, mucus-secreting cells which glandular cells that secrete mucus, and receptor and nerve cells which collect and transmit sensory information.

The inner layer, the endoderm , has cells that produce digestive enzymes and break up food particles. The jellylike material between the two layers is called the mesoglea. All of these body layers surround a central cavity called the gastrovascular cavity, which extends into the hollow tentacles.

Stem cells are the cells that have an ability to become various types of cells. They are present both during embryonic development (embryonic stem cells) and in the adult body (adult stem cells). Human ES cells differentiating into neuronsStem cells are simple, unspecialised cells found in animals and plants that have the ability to divide to form cells of the same type. They can also differentiate into a variety of specialised cells. Stem cells can be harvested from embryonic umbilical cord or adult bone marrow..A cell capable of differentiating into any type of cell is known as "totipotent". For mammals, totipotent includes the zygote and products of the first few cell divisions. There are also certain types of cells that can differentiate into many types of cells.

In each ecosystem, there are many feeding relationships. A food chain represents a flow of energy through an ecosystem, and always begins with an organism called a producer, which is able to trap light energy and convert it to chemical energy. An organism of this type is eaten by a herbivore, which is a kind of consumer that feeds only on plant material. This type of organism is, in turn, eaten by a carnivore (an organism that consumes other animals).

To answer the question, crust and mantle come under Compositional layers. The mesosphere and asthenosphere come under the Physical layers of Earth.

The Compositional layers of the Earth include the Crust, Mantle, and Core. The crust is the outermost layer of the Earth, where we currently live in. The mantle is the layer below the crust, and, by volume, the largest chemical layer as well. The Core is the innermost layer of the Earth, discovered by scientists in 1906.

The Physical layers of Earth include Lithosphere, Asthenosphere, Mesosphere, Outer core, and Inner core. The lithosphere defines as the outermost physical layer of Earth, which is broken into segments called plates. The asthenosphere is the layer residing below the lithosphere, has multiple plates, and is considered unbroken, unlike the lithosphere. The outer core is the only layer of Earth consisting of only liquid entirely, whereas the Inner core exists within the liquid outer core.
