Answer:
For natural selection to occur, it is true that there must be genetic variation in the population.
Explanation:
According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.
For natural selection to occur, three fundamental conditions must exist:
A trait that can be inherited from one generation to another.
The trait is subject to variability between subjects of the same species.
Genetic variability can determine the possibility of reproductive success and survival.
Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.
For natural selection to occur :-
There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.What is Evolution?It is the change in the characteristics of a species over several generation.It relies on the process of natural selection.

How have golden eagles adapted their behavior for living in temperate grasslands?
Golden eagles have adapted their behavior for living in temperate
grasslands by building their nests on the ground.
Temperate grassland is characterized by mainly grasses and very few
trees. Animals like the Golden eagle who build their nests on tall trees are
able to adapt to the absence of these types of trees in the grasslands by
building their nests in the ground.
They live in in pairs in the temperate grasslands to efficiently guard the
nest and hunt animals for their survival.

What are the two theories that are combined in the synthetic theory of evolution?
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island
Answer:
Organisms on the island would migrate to a larger island.
Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.
What is an invasive species?An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

Describe the weather after the passage of a cold front.
Answer:
As the cold front passes, winds become gusty. ... Atmospheric pressure changes from falling to rising at the front. After a cold front moves through your area, you may notice that the temperature is cooler, the rain has stopped, and the cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies.

The diagram shows an ocean food web. Which organism is a primary consumer? krill elephant seal Killer whale Elephant seal O squid O penguin Penguin Leopard seal Squid Cod Krill Zooplankton Phytoplankton
Answer:
Krill
Explanation:
If you look at the diagram for this assignment, you can see the main organism that produces its own food is the phytoplankton. The animal that eats that organism is called a primary consumer. So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D
Answer:
A. krill
Explanation:
None of the other organisms are primary consumers.

Using the __________ system, kingdoms are grouped based on cell structure and type, while the __________ system groups major taxonomic groups into three major domains.
Given what we know, we can confirm that using the using the Whitaker system, kingdoms are grouped based on cell structure and type, while the whoese-fox system groups major taxonomic groups into three major domains.
What is the Whitaker system?The Whitaker system is a classification system to order and organize the diverse biological life found on Earth. This is the most commonly-known system which orders organisms into the 5 kingdoms. What is the Whoese-fox system?This is a much less popular system of classification for biological life. It is considered to be much less specific, containing only 3 groupings.Therefore, we can confirm that based on the statement, the spaces missing correspond to the scientists for who the systems are named after, which are Whitaker and Whoese-fox.
