Who first suggested the theory of evolution by natural selection?
O A. Charles Darwin
B. Wilhelm Weinberg
C. Gregor Mendel
D. Thomas Malthus

Answers

Answer 1
Charles Darwin!
Darwin and a scientist contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection.
Answer 2

Charles Darwin first suggested the theory of evolution by natural selection.  Therefore, option (A) is correct.

Who was Charles Darwin?

Darwin was a British naturalist who conducted extensive research and observation during his travels around the world, and his work culminated in the publication of "On the Origin of Species" in 1859. In this seminal work, Darwin proposed that species evolve over time through a process he called natural selection, which involves the differential survival and reproduction of individuals with advantageous traits.

This theory challenged the prevailing view of species as unchanging, fixed entities and revolutionized the field of biology. While Darwin was not the first to propose the idea of evolution, his theory of natural selection provided a mechanism to explain how it occurs and remains one of the most important and influential ideas in the history of science.

Answers

Explanation:

male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains.

Insect pollinators include bees, (honey bees, solitary species, bumblebees); pollen wasps (Masarinae); ants; flies including bee flies, hoverflies and mosquitoes; lepidopterans, both butterflies and moths; and flower beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination.

A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process.

Express a
mass of 0.014 mg in grams

Answers

Answer:

14 mg

Explanation:

1 g = 10³ mg = 1000 mg

0.014 g * 1000 mg/1g = 14 mg

0.014mg in grams would be equal to 1.4 × 10^-5 gram.

What are unit conversions?

There are a few items that we track in our daily activities, including the following:

Speed \sTemperature \sArea \sVolume \sMass

Units of measure are needed in order to measure these values. Sometimes the units of measurement employed may not correspond to the standards required for a particular process or application, as well as the measuring choice and convenience.

It's crucial to convert these units in a way that makes sense and can be used effectively. Let's use the example of someone who is only familiar with the metric system to better grasp the statement.

The person finds it difficult to determine the height of a 25-foot tree. The individual will comprehend the height of the tree better if they convert 25 feet to meters.

Therefore, the conversation of 0.014 mg in grams would be by 0.014/1000 = 1.4 × 10^-5 gram.

2. In the example of the white and brown mice, vultures will prey on both colors of mice. However, in
the desert environment, the brown mice are better able to hide from their predators and have an
advantageous trait. What will happen to the color of mice over time?

Answers

Answer:

The brown color of mice would become more common in the population of the mice in the desert overtime

Explanation:

In the mice population, since the environment favors the individuals with brown fur color over individuals with white fur color, as it makes them better able to escape from predatory vultures, white mice gets eaten more often. With time, the population of white mice reduces while that of brown mice increases.

Overtime, brown mice leaves more offspring with its trait compared to white mice. As a result of this, the color mice that would be more common in the desert environment would be mainly brown colored mice, while white mice would be few.

How can that influence the oxygen and carbon cycles?


Are there other cycles involved that have not been mentioned in this question?


What does this discussion suggest about the nature of the Earth as one large system?

Answers

Answer:

1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.

The second question im not sure sorry- the positive and negative one ;(

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.

5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.

6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

Answers

Answer:part c transportation

Explanation:

The process directly responsible for root growth in plants is cell division. So, the correct option is D.

What is Cell division?

The process by which a cell divides into two or more daughter cells is called cell division. In relation to the above question, cell division is the mechanism due to which plant roots grow.

The meristematic region, which is in charge of cell division, is designated as part D in a cross-section illustration of the root tip of a plant. The meristem of the root is a unique region where cells continuously divide and differentiate into different tissues, helping the root to expand and mature.

Many tissues of the root, including the epidermis, cortex, and vascular tissue, are composed of distinct types of cells that differentiate when they divide into specialized cell types.

So, the correct option is D.

Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.

A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.

Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.
