Explain the 4 parts of Darwin's Theory Parts.
1. Variation
2. Overpopulation
3. Adaptation
4. Descent with Modification
Your answer:
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.
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASEAnswer:
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

Answer:
Macro-capsule: thickness of 0.2µm or more, visible under light microscope
Microcapsule: thickness less than 0.2µm, visible under Electron microscope
Explanation:
It has several functions: promote bacterial adhesion to surface or interaction with other organisms; act as a permeability barrier, as a defense mechanism against Phagocytosis and/or as a nutrient reserve. Among pathogens, capsule formation often correlates with pathogenicity
correct me if I'm wrong
Answer:
Capsule (also known as K antigen) is a major virulence factor of bacteria, e.g. all of the principal pathogens which cause pneumonia and meningitis, including Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Klebsiella pneumoniae, Escherichia coli, and group B streptococci have polysaccharide capsules on their surface. Nonencapsulated mutants of these organisms are avirulent.

A) the presence of igneous rocks
B) the presence of sedimentary rock
C) the presence of metamorphic rock
D) the presence of carbonate rock types
E) the presence of granite rock features
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.

Several species of finch live on the Galapagos Islands. They are very similar in appearance, but have adapted beaks of different sizes and shapes based on their major food source. Finches with large beaks eat mainly large seeds and cacti. Finches with small beaks eat mainly small seeds and insects. Which of the following best explains the variety of beaks found in finches on the Galapagos Islands? A. Evolution through natural selection always causes a decrease in the species diversity of an ecosystem. B. Biological evolution does not have any effect on the species diversity of an ecosystem. C. Biological evolution only affects the species diversity of plants in an ecosystem. D. Evolution through natural selection can increase the species diversity of an ecosystem
Answer:
D is the correct answer
Explanation:
Evolution by natural selection can only act on traits initially present. In the common ancestor, there would have been one beak, but in the offspring, there would have been variation in beak size and shape. As natural selection acts on that variation, different species end up with traits adapted to different conditions, thus increasing the species diversity.

content of the upper 400 mm depth is 15% and that of the
lower 600 mm is 20%. The bulk density in the upper layer is
1300 kg m- and in the lower layer is 1500 kg m-?. Assume Pw

metres) per 1.5 hectares of land?
ri
The equivalent depth of water in the soil is 270 mm and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.
How can equivalent depth of water in a soil be calculate?The equivalent depth of water in a soil is calculated using the formula below:
equivalent depth of water = water content × depth of soilThe depth of soil profile 1 = 1 m = 1000 mm
The depth of soil profile 2 = 600 mm
Equivalent depth of water in the soil = 15% × 1000 mm + 20% × 600 mm
Equivalent depth of water in the soil = 150 mm + 120 mm
Equivalent depth of water in the soil = 270 mm of water
The volumetric water content of the soil is calculated using the formula below:
Volumetric water content = water content × bulk density of soil/density of water × height of soilHeight of soil profile 1 = 1 m
Height of soil profile 2 = 0.6 m
Volumetric water content of soil profile 1 = 15% × 1300/1000 × 1 m = 0.195 cubic meter/square metre of soil
Volumetric water content of soil profile 1 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil
Total Volumetric water content of soil = 0.18 + 0.195 = 0.375 cubic meter/square metre of soil
Converting to cubic meter/hectare of soil:
0.375 cubic meter/square metre of soil
1.5 hectares = 15000 square metre
Volumetric water content of soil = 0.375 × 15000 cubic meter/ 1.5 hectare of soil
Volumetric water content of soil = 5625 cubic meter/ 1.5 hectare of soil
Therefore, the equivalent depth of water in the soil is 270 mm of water and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.

What process will you use to recover salt which has dissolved in water?
Explanation:
You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.
