Answer:

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

Explanation:

Answer:

As the quantity of liquid is bigger it will take longer to freeze because more energy will have to be used. There is a state of matter that water has which is called super cooling this is where the water is at a freezing tempture but ice crystals haven't be formed correctly. Different liquids freeze at different temperatures. Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Thicker liquids will freeze more slowly and some will not freeze at all.

Explanation:

The phylogenetic tree shown shows tree finches and cactus finches have a common ancestor. So, the correct option is D.

A branching diagram that depicts the evolutionary relationships between a set of creatures, species, or genes is called a phylogenetic tree, sometimes referred to as an evolutionary tree. On the basis of the similarities and contrasts in their physical or genetic traits, it depicts the evolutionary history of these groups.

We can draw the conclusion that cactus and tree finches are more closely connected to one another than they are to any other finch species on the tree. The diagram does not indicate if tree finches and warbler finches are more or less closely related to one another, or whether cactus finches and warbler finches are.

Therefore, the correct option is D.

Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.

The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.

Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

Explanation:

Answer:J

Explanation:Substitution

Mutation in genes can result in different types of abnormalities. In gene related to hemoglobin makes RBCs sticky, irregular shaped, this is because of substitution.

Mutation is a type of replication error during formation of new DNA.

In substitution mutation, incorrect nucleotide is placed at incorrect position during DNA replication, a point mutation occur in which a single nucleotide is substituted.

It actually does not add or remove any nucleotide from the sequence, just it substitute it.

In gene related to hemoglobin, the amino acid glutamic acid gets replaced with the valine amino acid at position 6 in beta-globin, which results in sticky, irregularly shaped red blood cells.

Thus the correct option is J.

Answer:

The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

Explanation:

Answer:

13 protons

Explanation:

Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.

However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.

Answer:

D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.

Explanation:

Carbondioxide gas is the main reactant for the process of photosynthesis which decides the production of food in the leaves. If plants has high amount of carbondioxide gas and water so in the presence of sunlight it produces more food in the leaves in the form of glucose so we can conclude that the  lowest rate of photosynthesis occurs due to presence of least concentration of carbondioxide gas in the cup 4.

Answer:

Playa lakes.

Explanation:

A habitat can be defined as the natural living location or place of both living and non-living organisms. Some of the main components that makes up a habitat required for an organism to survive includes space, shelter, water and food.

Migratory birds refers to a group of bird leaving there natural living location or place in search of resources such as food and water in order to survive.

The High Plains have over 20,000 playa lakes, that are important stopover habitat for migratory birds like ducks and geese in search of scarce feeding resources which includes water and food. Playa lakes comprises of living organisms such as invertebrates, seeds and plants, that provides the optimum level of energy required by the migratory birds that are flying from one location to another.
