What feature about water gives it such unique properties?
Its polarity and bond angle
Water being made up of oxygen and hydrogen
Water being able to dissolve substances
Water being in all cells
Its polarity and bond angle makes water unique properties.
The structure of water molecules is twisted and polar, with partial positive charges on the hydrogens and partial negative charges on the oxygen. This is because oxygen attracts electrons more effectively than hydrogen since it is more electronegative. A great solvent is a water.
Cohesion in water is caused by its polarity. The forces that induce or permit similar molecules to stick together are referred to as cohesion. Water has cohesiveness because its molecules naturally desire to adhere to one another.
When water is not boiling into a gas or freezing into a solid, it is in a liquid condition. When it is liquid, water has the lowest density.

Lion Phylogeny: Finding connections Based only on eht DNA which populations do you think live closer in proximity to each other
The depiction of the evolutionary history and connections between groupings of species is known as phylogeny. The findings are shown in a phylogenetic tree, which shows connections based on common or divergent morphological and genetic features.
The word "phylogeny" comes from Haeckel's 1866 introduction of the German Phylogenie, and the Darwinian approach to categorization got recognized as the "phyletic" approach.
By observing the given DNA samples of the different lion species, we can say that Cameroon, Tsavo, Fannie Roberta, Umfolozi, Zimbabwe, Zambia, and Kalahari lions are linked together and divided from Sabi sands, Botswana, and Etosha lions due to differences in their cytochrome b gene. The complete division will be as follows.
This phylogenetic tree explains that all the given species have originated from a common ancestor who had T (thymine) nucleotide in the DNA at some sites. The thymine changed to C (cytosine) to develop new species. This change was done by a point mutation.

Explain what happens to the lithosphere with each of the following plate boundaries
1. Divergent Boundary
2. Continental-Continental Convergent Boundary
3. Continental-Oceanic Convergent Boundary
4. Oceanic-Oceanic Convergent Boundary
5. Transform Fault Boundary
1) Plates separate and new seabed is created. 2) Plates collide, obduction occurs, and inland mountain chains are created. 3) Plates collide, subduction occurs, and mountain volcanic chains are created. 4) Plates collide, subduction occurs, and volcanic arcs are created. 5) Plates slide, no material is created, and displacements occur.
What are the three types of boundaries?
I. Divergent
New crust is created by the rising molten materials coming from the mantle.
Two plates separate, and the stream of hot material creates a new seabed between them. It occurs in an expansion of the sea bottom.
As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge.
An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.
II. Convergent.
When two plates move forward to each other, they end up colliding and causing the deformation of one or both plates.
Three possible collisions might occur,
Two oceanic plates might collide ⇒ subduction
The thickest plate subduces and causes a deformation on the other plate edge, creating an oceanic trench.
Hot magma rises to the surface by these trenches and creates volcanoes on the superior plate. These volcanoes can be underwater or can emerge from the ocean surface, forming island arcs or an insular volcanic arc.
Japanese islands and the Philippines are examples.
Two continental plates might collide ⇒ obductionBoth plates are too light to subduce (equally dense), so neither of them sinks under the other one.
Occurs a vertical deformation on both plates' edges, which remain attached by a suture area. The result is an inland mountain chain formation.
The highest mountains on the Earth were created by this process. Examples of these are Alpes, Urales, and Himalayan mountains.
Oceanic plate and continental plates collide ⇒ SubductionThe oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The result is the formation of mountain chains or volvanic chains due to the deformation caused on the continental plate edge.
The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur on the continental plate.
No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
The San Andrés fault is an example of these plate ridges.
1. Divergent Boundary
Plates separate and new seabed is created.
2. Continental-Continental Convergent Boundary
Plates collide, obduction occurs, and inland mountain chains are created.
3. Continental-Oceanic Convergent Boundary
Plates collide, subduction occurs, and mountain volcanic chains are created.

The theory of island biogeography suggests that island colonization is affected by which of the following factors?
Allopatric speciation
Ecological tolerance
Adaptative evolution
Migration rates
The theory of island biogeography explains that two factors affect island colonization. These are migration and extinction, associated with the distance from the mainland and the island size. Option D. Migration rates.
What is the theory of island biogeography?
The ecologists MacArthur and Wilson took the term island biogeography to refer to the predictions about the number of species inhabiting an island.
According to MacArthur-Wilson (1967)
The number of species on an island represents a dynamic equilibrium between the opposite forces of immigration and extinction rates. At equilibrium, the species richness keeps constant. But the species composition changes.Each island can have a certain number of species, but these species are not always the same, meaning that species might renew. Interspecific competition has a significant role.Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance from the mainland and the size of the island.
At the same time, these factors affect immigration and extinction rates.
According to the theory,
Effect of distance ⇒ islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. Effect of size ⇒ relation between island size and species diversity. On smaller islands, the probability of extinction is higher than on bigger islands. Bigger islands can have more species than smaller ones.The assumptions of the equilibrium theory:
The immigration rate depends on the distance of the island to the mainland.The extinction rate depends on the island size.All the species have the same chances of getting to the island.Predictions:
At equilibrium, the number of species is constant in time.Dynamic equilibrium means continuous species renewal.If the island gets bigger, species richness increases.If the island is closer to the mainland, species richness increases.The correct option is Migration rates. Option D.
