Answer 2

A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.

What are parts of a flower?

The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.

Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.

Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.

Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.

Thus the given parts are petal, stigma and stamen.

A boat is traveling to the right at 300 N, the current is going to the left at 600N. What is the net force and direction?

Answers

it would be 800n to the right
i’m pretty sure it’s 300 N but it could also be 800 N . the only reason i thought it was 300 N was because since they go the other direction they should cancel each other out by doing 600 - 300 which is 300 N. but yeah

Why is it necessary to see a similar pattern of change in fossils from several places in order to conclude that an extinction happened?

Answers

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

One can learn a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.

What are fossils ?

Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.

Scientists use the fossil record to seek for patterns that may be used to infer which creatures are related to one another, how groups of organisms evolved through time, and how the Earth's climate affected the kinds of plants and animals that could survive for a very long time.

Thus,  a lot about the history of life on Earth thanks to fossils. They can help us understand the origins of life and humanity.

What patterns in the rock layer fossils helped you identify an extinction?

Answers

Answer:

Hope this helps!! :D

Explanation:

Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

You can often tell by disturbances in the fossils bones. Maybe like dust or particles symbolize harm or mass extinction in a prehistoric animal or maybe even new fossils like some animals that went extinct recently like 200 years.

How does melanin provide protection against skin cancer? use absorb
energy
light in your sentece

Answers

Energy for the light can cause skin cancer and damage genetic materials (melanocytes) however melanin absorbs the light meaning the genetic material in their skin cells are protected from any damage so in conclusion the more melanin in the cells the more their cells are protected

The melanin provides protection against skin cancer by absorbing harmful UV light from the electromagnetic spectrum.

What is electromagnetic spectrum?

The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Graphite is most likely to break apart with cleavage due to the fact that the carbon atoms in graphite,from sheets, could split easily in layers. Graphite had cleavage as the weak bonds in the layers can easily break. It’s unlikely to fracture as fractures usually break in jagged pieces. Atoms in graphite are arranged in layers.
