Mt. Mayon examples is NOT classified as composite volcano.

What is Composite volcano?

Cone-shaped composite volcanoes, also known as stratovolcanoes, are formed from numerous layers of lava, pumice, ash, and tephra. Composite volcanoes typically generate tall peaks rather than rounded cones because they are composed of layers of viscous material rather than fluid lava.

Calderas are occasionally created when the peak crater collapses. The most destructive volcanic eruptions in recorded history have been caused by composite volcanoes.

Apart from Earth, Mars is the only known location in the solar system with stratovolcanoes.

Therefore, Mt. Mayon examples is NOT classified as composite volcano.

A ________ is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.

Answers

Answer:

A fungi  is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.

Explanation:

FUNGI -: Fungi can be single-celled organisms or multicellular organisms with a great deal of complexity. They can be found in almost any habitat, but the majority of them reside on land, primarily in soil or plant material, rather than in the sea or fresh water. Decomposers are organisms that live in the soil or on dead plant materials and play a vital part in carbon and other element cycling. Some are plant parasites that cause illnesses such mildews, rusts, scabs, and canker. Fungal diseases in crops can cause a farmer to lose a lot of money. Animals are afflicted by a small number of fungus. Athletes' foot, ringworm, and thrush are examples of human skin diseases.

Fungi play an important part in the breakdown of organic materials and in the cycling and exchange of nutrients in the environment. They've long been utilized as a direct source of human food in the form of mushrooms and truffles, as a bread leavening agent, and in the fermentation of a variety of foods like wine, beer, and soy sauce.

Hence , the answer is fungi.

What is an adaptation? Give an example of one.

Answers

Answer:

Adaptations are special skills that help animals survive in their environments. For example, in order for pelicans to catch their prey, they use their pouch-like beaks to scoop up fish. This is an example of physical adaptation; the animal is using its body parts to help it survive.

Explanation:

My answer is self-explanatory; this is not plagiarized.

It is the action of adapting to something. For example, if a wild fire wides out 40 acres of forest then all the animals that lived there would have to find somewhere else to live and adapt to their new environment.

In the year 100, Ptolemy introduced the geocentric model of the solar system. By the year 1542,
Copernicus introduced a new model of the solar system called the heliocentric model. With this
example in mind, which of the statements below best summarizes what we learned from these models?

Answers

Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

What is Nervous system?

Signals are sent from the brain to the rest of the body, including the internal organs, via the nervous system. Thus, the nervous system's activity regulates a variety of functions, including the capacity to move, breathe, see, and think.

The nerve cell, or neuron, is the building block of the neurological system. There are around 100 billion neurons in the human brain. A neuron has a cell body, which contains the cell nucleus, as well as distinct extensions known as axons and dendrites.

Different neuronal types control or carry out various functions. For instance, motor neurons help the brain send signals to the muscles that cause movement.

Answers

Answer:25 , 0

Explanation:

XX©(mother being the carrier as her father was hemophilia- females can only be carrier of hemophilia ) when crossed with normal father produces offspring XX©, XY, XY©, XY. Therefore chances of boy being hemophilia=(1/4)*100=25.

[4 marks]

Answers

Answer:

a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population

Explanation:

A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.
