Given parameters:

Number of lizards  = 150 lizards

Area of the study = 25km²

Unknown:

Population density = ?

Solution:

Population density refers to the number of organisms per area in a particular location.

Mathematically;

     Population density  = [tex]\frac{Total Population}{Area}[/tex]  

    Population density  = [tex]\frac{150}{25}[/tex]   = 6lizards/km²

The population density of the study area is  6lizards/km²

Answer:

The correct option is A. Bacteria are prokaryotes and protists are eukaryotes

Explanation:

The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.

The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.

Therefore the answer that best explains the difference between both protists and bacteria

Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.

Answer:

In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.

Hope this helps!

:)

The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:

Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.

This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.

In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.

Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.

For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.

Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.

In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,

Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.

Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.

Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.

Answer:

Gravity, Electrostatic force, Magnetic force

Explanation:

A non-contact force is a force that is applied to an object by another object without contact. Gravity, electrostatic force, and magnetic force all don't need two objects to be touching in order for them to work.

On the other hand, an example of a contact force is friction, because it can only occur if two objects are touching. If you want to tell the difference between a contact and non-contact force, just ask yourself if it can occur if the two objects are not touching. If it can occur while two objects aren't touching, it is non-contact, and if it can't, it is contact.

All the options given describe a force that involves contact except for the force exerted by magnets. Thus, the correct option is C.

Magnetic force is the force exerted by magnets. It can be described as the effect exerted on a charged particle due to the magnetic field of the other particle.

It is a consequence of the electromagnetic force, which is caused due to the movement of electrically charged particles.

Two objects that are oppositely charged will have a magnetic force of attraction, whereas two objects that have the same charge will have a magnetic force of repulsion.

Answer:

1. An organism is a individual animal, plant, or single-celled life form.

2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.

3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.

4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.

5. Pollution(water&air), deforestation, UV Radiation, invasive species.

Cotton plant

Southeastern North America

The plant lives in soil in an agricultural field.

The cotton plant requires bees for pollination.

The plant may be threatened by diseases such as cotton leaf curl disease, pests such as aphids, and drought.

If cotton became extinct, my pants would have to be made of some other material, such as linen or wool, which would feel quite different. This would be a big adjustment for me because I am used to wearing cotton pants almost every day.

Answer:

D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.

If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.

The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.

Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.

If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.

Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

Green plants absorb energy from the sun when "A photon strikes electrons in special molecules in a cell"

Green plants are unique organisms being that they possess the ability to capture and utilize energy from the sun. This is possible because they possess special pigments in their CHLOROPLAST called CHLOROPHYLL. The general process whereby green plants capture and utilize sun's energy is called PHOTOSYNTHESIS.

During photosynthesis, a photon of light strikes electrons in the thylakoid lumen of the chloroplast. This facilitates the synthesis of ATP (energy) in further reactions that takes place in the chloroplast.

Therefore, green plants are able to obtain energy from the sun when photons (beam of light) strikes electrons in their CHLOROPLAST.
