Answer:

Tubercle: allows tendons to attach to bone

Foramen: Allows blood vessels and nerves to travel through bone.

Fossa: Allows to bones to form a joint.

Explanation:

Tubercle is a small round prominence on the bone which helps in the attachment of tendons to the bones.

Foramen means aperture or hole, through which blood vessels and nerves can pass through.  For example: Vertebral foramen. Vertebral foramen of all the vertebral bones together form the vertebral canal. Blood vessels pass through the vertebral foramen. Another example is foramen magnum in the occipital bone.

Fossa is small depression on the surface of bone where articulation can occur. Example: radial fossa- is a depression which articulated with head of radius when the forearm is raised. Olecranon fossa receives olecranon of ulna when forearm is extended.

Explanation:

Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.

And, when the chemical reaction takes place between the given elements and compounds then they change into products.

For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.

But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.

In a chemical reaction, the term used for the elements and compounds present before the reaction takes place is 'reactants'. These undergo a chemical reaction to form the 'products'.

In a chemical reaction, the substances that are present before the reaction takes place are referred to as the reactants. These could be individual elements or compounds that chemically interact with each other. For instance, in the formation of salt (NaCl), sodium (Na) and chloride (Cl) are the reactants. After the reaction has taken place, the substances that are produced are referred to as products.

Furthering the explanation with another example, let's consider water's formation. The reactants in this chemical reaction are hydrogen and oxygen, which are the elements. They react to form water, which is the product and a compound. The chemical equation would be: 2H + O -> H₂O. The arrow indicates the direction of the reaction, from reactants to products. Thus the term used for elements and compounds before a chemical reaction is 'reactants'.

D. because of their ancestors being able to survie the plague it will be easier for their decendants to be more resistant to similar diseases.

Final answer:

The hypothesis that the survivors of the plague passed on protective genes to their descendants, leading to some resistance to HIV infection, is supported by a blend of biological, environmental, and social factors influencing immune competence.

Explanation:

The most likely hypothesis that explains why about 10% of the modern descendants of those who survived the plague in Europe between 1347 and 1350 have a resistance to infection by HIV is that the individuals who survived the plague passed on genes to their modern descendants who allowed them to be resistant to HIV. There is scientific consensus that exposure to the plague pathogen during medieval times did not generate a long-lasting immunological memory. However, those who had stronger immune systems due to certain genetic traits were more likely to survive and pass these favorable genes onto their offspring. Over generations, this resulted in a population with a higher prevalence of these protective genetic traits, which appears to convey some resistance to HIV. This observation underscores the significance of the interaction between biological, environmental, and social factors in shaping immune competence (IC), which can vary greatly among individuals and populations.

Motion energy, or the more common term, mechanical energy is the energy stored in objects.  

The more an object moves faster, the more energy is stored.  Some examples of motion energy include wind, a flowing river, a moving car, or a person running.

Final answer:

Mechanical energy is the energy associated with moving objects or storing energy, such as in kinetic or potential forms. Other forms like chemical, sound, and electrical energy can be transformed into mechanical energy. A car's movement exemplifies kinetic energy, while a compressed spring showcases potential energy.

Explanation:

The question refers to energy that comes from moving objects or stored energy sources. This type of energy is commonly known as mechanical energy, which is the sum of kinetic and potential energy in an object. Kinetic energy is the energy of motion, while potential energy is stored energy that is ready to be converted into other forms. For instance, a moving car has kinetic energy, and a compressed spring has potential energy.

Other forms of energy mentioned include sound energy, which involves the vibrations of matter; chemical energy, associated with the arrangement of atoms in molecules such as in food or fuel; and electrical energy, coming from the movement of electrons. Each of these forms of energy can be converted from one to another, like chemical energy converting to mechanical to power a car, or electrical energy converting to light in a bulb.

Understanding these forms of energy and their conversion is essential. For example, when you use a battery, it releases chemical energy which is then converted into electrical energy to power devices. Similarly, when you speak, your vocal cords vibrate to produce sound energy.

I think it is abiotic if it is not i am sorry

Answer:

The correct answer is abiotic factors.

Explanation:

A non-living constituent in the environment is known as an abiotic factor. This can be either a physical presence or chemical. The abiotic factors come in three fundamental categories. These are edaphic, climatic, and social. The edaphic factors comprise conditions of the soil, the climatic factor comprises sunlight, humidity, and other factors taking part in the climate. The social factors comprises the water resources in the region, and how the land is used. The five general abiotic factors are chemical elements, atmosphere, temperature/sunlight, water, and wind.  

Answer:

C

Explanation:

This layer is called the mantle and is formed of semi-plastic rocks (liquid enough to churn but the rocks are not really melted because of the enormous pressure of the overlying crust above). The layer is heated from below by the core that is hotter, The hotter mantle rises as it gets less dense while the cooler mantle at the upper layers sinks because it is denser. These convections drag with them the continental plates of the crust.  

Convection currents in the Earth's mantle are responsible for the movement of tectonic plates. These currents result from the heating, rising, cooling, and sinking of mantle material. The movements of these plates result in phenomena such as earthquakes and volcanoes.

The convection currents responsible for the movement of tectonic plates occur in the mantle region of the Earth. This is the layer between the crust and the outer core that accounts for about 84% of Earth's volume.

In this region, heat from the Earth's interior causes the material in the mantle to heat up and become less dense, causing it to rise. Once it reaches the top of the mantle and comes close to the Earth's crust, it cools, becomes denser, and sinks back down. This cycle is repeated over and over to create convection currents which provide the force that ultimately causes the movement of the tectonic plates.

These moving plates are responsible for geologic phenomena such as earthquakes, volcanoes, and mountain building. This complexity of plate tectonics is a fundamental concept in geology, highlighting the dynamic nature of our planet.

Explanation:

21. The structure of cell shape is not maintained by the cell membrane, Rather it is the product of the cytoskeleton which is the filaments and microtubules in the cell. They change the shape of the cell by contracting and relaxing. They also control the internal organization of organelles inside the cell.

22. Psychrophile bacteria thrive in low temperatures which they are adapted to. They can be expected in the polar regions and deep seas. Their metabolism can function in these low temperatures because their cells have antifreeze protein that protects the cells from ice-induced desiccation and damage.

23. Thermophiles are extremophiles that thrive in high temperatures. They can be expected in hydrothermal vents. They have heat-stable proteins and enzymes and DNA (that has high G-C content) that is not easily denatured at high temperatures.

24. This phase is called  the stationary phase. The  reproduction rate is equal to the death rate. This is because the population has reached its carrying capacity. This is why there is no growth in population.
