An available niche after extinction can lead to speciation because it allows the emergence of genetic variation in other competing species.

Speciation is a slow process associated with the emergence of reproductive isolation barriers in a population.

These barriers lead to the absence of gene flow and eventually to the emergence of new species.

In conclusion, an available niche can lead to speciation in other competing species.

Answer: OC. Isotopes

Explanation: Isotopes of element are those who have same numbr of protons but different number of neutrons. Here number of neutrons are different so these atoms are isotopes.

If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The correct option is A.

In order for the outcomes of scientific experiments to be reliable, constant variables should be kept constant.

In the illustrated experiments, the breed and age of the experimental dogs have to be the same. It is one of the variables that have to be kept constant throughout the experiment.

If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The same thing is applicable to different ages.

Thus, evaluating this variable and doing right by it will ensure reliability.

Answer: Summer

Explanation: When the southern hemisphere is closest to the sun, and it receives the most sunlight it is summer time, while in the northern hemisphere it's winter.

The main factor that determines seasons is the way sun rays enter Earth, and not as much proximity, since there is only a 2% variation in the distance overall

Eubacteria and archaebacteria are organisms from the Archaea domain, whereas protists and Fungi belong to the Eukarya domain.

Prokaryotic organisms such as eubacteria (E coli) and archaebacteria (methanogens) are unicellular microorganisms whose cells do not have a cell nucleus.

Conversely, eukaryotic cells such as protists (giardia lamblia) and fungi (Yeast) have the genetic material inside the cell nuclei and membrane-bound organelles.

In conclusion, eubacteria and archaebacteria belong to Archaea, whereas protists and Fungi belong to Eukarya.

Reactions, where an electron (or hydrogen) passes from one atom or molecule to another, are called oxidation-reductions

A chemical reaction known as an oxidation-reduction (redox) reaction includes the exchange of electrons between two substances. Any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by acquiring or losing an electron is referred to as an oxidation-reduction reaction.

Oxidation reaction: An oxidation reaction is a chemical reaction in which oxygen is acquired or hydrogen is destroyed. such as the 2Cu+O2heating 2CuO Reduction response. Reduction reactions occur when either hydrogen or oxygen is acquired or lost. such as CuO+H2heating Cu+H2O

When a reactant loses electrons in a reaction, oxidation takes place. When a reactant obtains electrons during a reaction, reduction takes place. This frequently happens when acid and metals react.

The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.

Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.

With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.

Greenhouse gases are gases that are trapped in the Earth's atmosphere and absorb energy. These gases, which include carbon dioxide, methane, and nitrous oxide, are all released when fossil fuels are burned.

A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.

The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.

The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.

The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

Peru is the country that often experiences the first and worst effects of El Nino, including severe flooding.

El Nino is a climatic pattern which describes the unusual warming of surface waters and it is part of a larger phenomenon called 'El Nino - southern oscillation (ENSO)'.

ENSO includes the El Nino and La Nino, the warm phase and cool phase respectively. El Nino occurs irregularly at two - seventy years intervals.

El Nino events are indicated by the increase in sea surface temperature by 0.9 Fahrenheit for at least five successive three months intervals.

El Nino has devastating impacts on the Peruvian and Ecuadorian economies. They cause an increase in precipitation which results in a drastically increased rainfall contributing to coastal flooding and erosion. It also destroys buildings, crops and limits transportation.

The predicated frequency of homozygous dominant rats at are: 0.11 (Option A). See the explanation below.

A homozygous organism has two copies of the same allele for a gene.

If an organism has two copies of the same dominant allele, it is homozygous dominant; if it has two copies of the same recessive gene, it is homozygous recessive.

Note that the total population of rats is: 200

Number of rats with brown fur = 112

The frequency of brown fur rats thus,

112/200

= 0.56

Note that it is also stated that the brown fur rats are dominant in relation to the gray fur rats. Thus, in accordance to Hardy Weinberg's equation, the frequency of the dominant rats is depicted as: p²

Thus:

p²  + 2pq = 0.56

Hence, the frequency of the the Homozygous recessive gray rats is given as:

p² + q² + 2pq = 1

q²  = 1 - 0.56

q² = 0.44

q = 0.663

P = 1-q

= 1 - 0.663

= 0.337

Thus the frequency of the homozygous dominant rats is:
p²

= 0.337²

= 0.1135

≈ 0.11

The formation of multicellular organisms commences with a single-celled zygote, which divides rapidly to form the blastula. Cleavage refers to the rapid, multiple shots of cell division.

Following conception, the baby enters the embryonic stage, a period of radical shift.

This stage lasts from the fifth to the tenth week of pregnancy. During a certain stage, the baby is referred to as an embryo. Several changes take place even during embryonic stage.

The primary distinction between an egg and an embryo is that an embryo is formed after the gametes are fertilized, whereas an egg is extracted from the ovary and stored in a freezer prior to fertilization.

Thus, multicellular organisms begin with a single-celled zygote that divides speedily to form the blastula. Cleavage is a term that refers to rapid, multiple strikes of cell division.
