A measuring cylinder contains 40 cm3 of water. When a stone of mass 69 g is dropped into the water, the stone sinks and the water level rises to the 70 cm mark. (a) Calculate the volume of the stone. (b) Calculate the density of the stone.​ ( ignore the subject. the subject is science.)

Answers

Answer 1

Answer: 2.3 g cm^3

Explanation: In this case the rise in level of water is same as the volume occupied by the stone.

a) Volume occupied by the stone = 70 cm^3 – 40 cm^3= 30 cm^3

b) Density = mass/volume

                  = 69g/30 cm^3 = 2.3 g cm^3

Explain the 4 parts of Darwin's Theory Parts.
1. Variation
2. Overpopulation
3. Adaptation
4. Descent with Modification
Your answer:

Answers

Answer:

The key points for the Darwin theory are

Explanation:

Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection.

Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.

What is evolution?

The basic idea of biological evolution is that populations and species of organisms change over time. Today, when we think of evolution, we are likely to link this idea with one specific person: the British naturalist Charles Darwin.

In the 1850s, Darwin wrote an influential and controversial book called On the Origin of Species. In it, he proposed that species evolve (or, as he put it, undergo "descent with modification"), and that all living things can trace their descent to a common ancestor. What exactly is a species?

Darwin also suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time. What does "heritable" mean?

In this article, we'll take a closer look at Darwin's ideas. We'll trace how they emerged from his worldwide travels on the ship HMS Beagle, and we'll also walk through an example of how evolution by natural selection can work.

Early ideas about evolutionInfluences on Darwin

Darwin and the voyage of the Beagle

Darwin's seminal book, On the Origin of Species, set forth his ideas about evolution and natural selection. These ideas were largely based on direct observations from Darwin's travels around the globe. From 1831 to 1836, he was part of a survey expedition carried out by the ship HMS Beagle, which included stops in South America, Australia, and the southern tip of Africa. At each of the expedition's stops, Darwin had the opportunity to study and catalog the local plants and animals.

Over the course of his travels, Darwin began to see intriguing patterns in the distribution and features of organisms. We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador.

Answer:

individuals of a species are not identical; traits are passed from generation to generation; more offspring are born than can survive; and only the survivors of the competition for resources will reproduce.

Variation :

Within a population, some traits can be expressed in various ways and make individuals look and behave differently. It can be hair color, body size, eyes color, reaction while facing a danger, ...

Inheritance:

Heritable traits are transmitted to the next generation.

High rate of population growth:

At each generation, the population produces more offspring than what the local environment can support. It leads to substantial mortality.

Differential survival and reproduction:

Individuals with the best combination of traits to survive in the actual environment will produce more offsprings for the next generation

The presence of igneous rocks and granite rock features would support the theory of previous volcanic activity.

If an analysis of rock types in the area of the Acadia National Park shows the presence of igneous rocks and granite rock features, it would support the theory that the rocks in the area were formed from previous volcanic activity.

Igneous rocks are formed from the solidification of magma or lava, which are products of volcanic activity.

Granite is a type of igneous rock that forms from the slow cooling and solidification of magma beneath the Earth's surface.

The presence of sedimentary, metamorphic, or carbonate rock types would not support the theory of previous volcanic activity because these types of rocks are formed through different processes, such as sedimentation, heat and pressure, and chemical reactions.

Answers

Answer:

Pollination.

Explanation:

Removing a flower’s stigma would initially affect pollination.

Removing a flower’s stigma would initially affect pollination.

The stigma is found in the pollen-bearing part of the flower, which is called the “gynoecium”. The stigma’s primary purpose is to pull pollen grains out of the air using its sticky tip in order to reproduce.

If a flower does not have an anther or stigma, then the flower may be cross-pollinated. Cross-pollination occurs when pollen from one flower fertilizes the pollen of another flower. In other words, pollen from one plant fertilizes pollen from another plant.

When the stigma is taken off before pollination occurs, then the pollen grains do not collect in the receptive area of the flower.

What is the name of the Angle Jacob wrestled with in the bible plagerism COMPARISON OF PRIMARY AND SECONDARY RESEARCHPrimary research is the first research that is involved in collecting data. The primary researcher assembles first-hand information to form the basis of systematic analysis, rather than utilizing available data. Generally speaking, research is largely based upon specific needs, which often necessitates a large number of highly qualified individuals. Because of this, this type of research gives the researcher full control of the data, making it extremely useful in fast-paced environments. This is why many companies outsource market research to third parties. Unlike secondary research, primary research grants the investigator 100% control over the study data, which makes it extremely valuable." In secondary research, the secondary researcher does not have to gather first-hand information. In addition, research helps avoid knowledge repetition by mapping out previous research efforts, allowing the original researcher to concentrate on new areas of inquiry. On the other hand, research builds upon already gathered data to develop a systematized investigation. This implies that data is not actively collected by the researcher. In secondary research, the researcher does not acquire secondary data, so he or she cannot confirm the accuracy of the research materials. Secondary research can be accomplished relatively quickly and with few resources because the study data already exists unlike primary research, which is time-consuming and expensive.
