A volcano that is fairly symmetrical and has both layers of lava and pyroclastic deposits is a _____.cinder cone volcano


pyroclastic volcano


composite cone volcano


shield volcano

Answers

Answer 1
Answer:

Answer:

Composite cone volcano

Explanation:

Composite Cone Volcanoes are large volcanic buildings with long, generally conical shape, usually with a small crater on the summit and steep flanks, constructed by the interleaving of lava flows and pyroclastic products emitted by one or more conduits, which can be punctuated. over time by episodes of partial cone collapse, reconstruction and changes in conduit location.

Compound volcanoes are found in all regions of volcanism, but it is in plate convergence zones, where a tectonic plate subdows (plunges) toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are most abundant. The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.

What are the two types of behavioral adaptation

Answers

Answer:

The 2 types of behavioral adaptation are migration, and hibernation.

Explanation:

Adaptation of animal is the fitness towards its environment. If an animal can't adapt, it will perish with time. Adaptation may be genetic or acquired. But basically, adaptation is 2 types - physical adaptation, and behavioral adaptation.  

Physical adaptation includes the coloring of the body, camouflage activity of an organism. The behavioral adaptation is the respond of the organisms to their habitat. This includes hibernation, estivation, migration, etc.

Some animals are affected by the temperature difference of the environment. Therefore, they adopt some methods to survive in extreme temperatures.

The cold-blooded like amphibians hibernate during winter.  They undergo a long sleep during cold weather and become active in summer.  Similarly some animals like desert lizard active in the morning. When the temperature increase they burrow themselves under the ground. This is called estivation.

Birds migrate during the adverse season i.e. in winter. They temporarily go to a different place to spend the cold month and return during the advent of summer. This is one type of behavioral adaptation. They also migrate for better breeding ground and food.  

Some fishes also migrate for breeding and food.

All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.
Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.
Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.
The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

The reason why it is 50% is because the offspring gets 50/50 from both parents

Some people can curl their tongues. What evidence would support the hypothesis that tongue curling is an inherited trait?

Answers

its not an inherited trait. everyone is able to do this because they practice over and over again. 
but to make this hypothesis supported, you could go to people that have history with their parents being able to curl their tongues and them being able to curl their tongues too. 
tongue curling is an inherited trait bc if one of your family members have that trait you will to bc you are blood related

What is a organelle

Answers

An organelle is a functional subunit enclosed by a membrane within a eukaryotic cell. The name "organelle" means little organ and the name comes from the analogy with organs: what an organ is to a body, an organelle is to a cell. So, the organelle is the organ of the cell. There are different types of organelles in cells, such as nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, chloroplasts, vacuoles, and they all have a different function. For example, the nucleus is the organelle which main function is control of cell activities. Mitochondria are organelles which main function is energy production.
