Answer: lava flows, earthquakes
Explanation:
The primary succession begins in an area, where no life sustains initially. Such regions have no soil thus incapable of sustaining life. The land is considered primitive or underdeveloped.
The lava flow, retreating glaciers, sand dunes, earthquakes are the factors which are responsible for primary succession.
The lava will flow over a surface and will solidify into rocks. The rocks undergo withering. The earthquakes are responsible for disturbing the land.
earthquake, lava flows, severe landslides
Primary succession begins on a bare area, such as rock, without vegetation or soil.

Which statement accurately describes tectonic plate movement? Tectonic plate movement can be prevented with planning. Tectonic plate movement does not cause environmental change. Tectonic plate movement does not affect organisms. Tectonic plate movement is a long-term environmental change.
Answer:
Tectonic plate movement is a long-term environmental change.
Explanation:
Tectonic plate movement is a type of movement in which plates of the earth moves on another. Due to this movement, earthquakes occurs which adversely effected the environment of the earth surface. Due to these tectonic plate movement, eruption of volcano occurs which helps in the formation of new mountains and we know that mountains change the climate. These movements causes long-term environmental change because it changes the environment slowly and takes more time to change it.
Answer:
The correct answer is Tectonic plate movement is a long-term environmental change.

Why do plants often reduce the surface area of their leaves to help them prevent water loss?
Answer:
Explanation:
A typical leaf has three main layers. ... Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water los
Which describes vestigial structures and how they relate to evolution?
Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Humans and dogs have similar bone structures in their forelimbs, indicating a common ancestor
Dolphins and birds have structures that are adapted for swimming, but the structures did not evolve the same way.
The DNA of mice and chickens shows similar patterns, suggesting that the two species are related
Answer:
The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Explanation:
Minimal structures are the structures in a life form which are not, at this point being used. In past these minimal structures played out some significant capacities in those life forms however bit by bit because of development now they have become non utilitarian in their body.
Reptiles and snakes both are reptiles yet reptiles have a practical rear appendage which causes them in slithering, snakes have been developed from reptiles however so as to move they creep instead of creeping so their rear appendage doesn't serve any capacity in development. Rear appendages are available in their body as a minimal organ.
Thus, The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Answer: Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.

The source of energy shown in the image is ____. (renewable, nonrenewable, polluting) A drawback of building a dam is that _____. (It will destroy ecosystems, it requires fossil fuels, it won’t be useful for irrigation)
Answer:
The source of energy shown in the image is RENEWABLE. A drawback of building a dam is that it will DESTROY ECOSYSTEMS.
Explanation:
A drawback of building a dam is that it will destroy ecosystems (option A), and the water is also a renewable source as building a dam involves altering the flow of a river.
What is a dam?Building a dam can have a variety of impacts on the natural environment, some of which can be negative. One of the most significant impacts is that the construction of a dam can destroy ecosystems. Rivers and their associated ecosystems are dynamic systems that are adapted to the natural flow of water, sediment, and nutrients. When a dam is built, it changes the flow regime of the river, which can lead to the loss of wetlands, the alteration of the river's course, and the degradation of downstream habitats.
Hence, the drawback of building a dam is that it will destroy ecosystems (option A), and the water is also a -renewable source as building a dam involves altering the flow of a river.

State one effect the reintroduction of the wolf may have on the coyote population within the Adirondacks
effect. Explain why it would have this
Answer:
Decrease in the population of coyote occurs after the reintroduction of the wolf within the Adirondacks effect.
Explanation:
Wolves are the top predator in the ecosystem. They hate coyote and kill them and sometime eat them too. So the reintroduction of the wolf decreases the population of coyote by killing them directly and by consuming the prey and the coyote die due to hunger. Coyote feed on rabbit, snakes, deer, fruits and grasses so decrease in coyote population increases the availability of grasses and other animals for different animals.

Mendelian inheritance does not apply to the inheritance of alleles that result in incomplete dominance and codominance.
Why? How are the alleles in these two situations different from the alleles that Mendel studied?
Answer:
Explanation:
Phenotypes that Mendel studied was controlled by one gene that had two possible alleles, dominant and recessive allele. This made it possible to see just one or the other phenotype (total of 2 phenotypes).
Well now we know that a characteristic may be controlled by one gene with two alleles, but the two alleles may not have a traditional relationship of dominant and recessive. Which is why we see the patterns like codominance and incomplete dominance.
Codominance is when both alleles are expressed equally in the phenotype of the heterozygote. For example, you have a black flower and red flower, a codominant flower would have both black petals and red petals. Do you see how the traditional relationship of one being dominant and other being recessive no longer holds because you express both alleles.
Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents. SO a black and red flower would make an offspring with purple petals where neither of the alleles reigns supreme over other rather we get a mixture of both alleles.
The passing of the alleles from the parent to the offspring in a particular manner was given by Mendel, he defined the passing of the recessive and the dominant allele in a specific way from generations.
Mendelian inheritance does not apply to incomplete and co-dominance.
The exception of the Mendelian inheritance can be explained as:The condition in which the allele is not completely expressed in the progeny is called incomplete dominance while the expression of both the recessive and the dominant allele in the progeny together is called co-dominance.In the co-dominance case of hetero-zygotic phenotype, the allele is depicted equally. The law of recessive and dominance does not apply here and both the alleles are expressed in the progeny in equal ratio.In the incomplete dominance condition, the phenotypic character of the progeny is in the middle and a mixture of both the dominant and the recessive allele.Therefore, the Mendelian inheritance law does not apply to incomplete dominance and co-dominance.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
Answer:
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration
Explanation: Anaerobic cellular respiration occurs and due to the lack of oxygen she takes deeper breaths. That way, there's oxygen in the muscles while respiration occurs.
Answer:
Frida is lacking air, or oxygen, because of her exercising. She starts panting quickly to take in air faster and make up for the oxygen loss. The heart beats hard during exercise, and needs oxygen to return to a normal pace
