Besides Darwin, the theory of evolution by means of natural selection was also independently proposed by:
Answer:
Thomas Malthus
Explanation:
An article on the Principle of Population, written by Thomas Malthus in 1798, inspired Darwin's views as he grappled to comprehend what mechanisms could be during work to create evolution. Malthus proposed that populations of animals and plants, including humans, enlarged geometrically in quantities while the nutrients available only grew arithmetically. Thomas was also a key benefaction to Darwin's perception about the theory of limits put on the geometric growth of populations by nature.
Answer:
Hi, There! The Correct Answer Is Below!
Thomas Malthus is your Answer
Explanation:
Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection.

what parts form the small intestine?
Explanation:
The small intestine includes the duodenum, jejunum, and ileum.
Rocks , soil trees water air and life .How do all the parts affect each other? Give some
examples
Explanation:
Answer:
For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.

9.During exercise, blood flow to skeletal muscles increases. The initial response that increases blood flow is automatic in independent of the nervous and endocrine systems. Which type of homeostatic regulation is this (extrinsic or intrinsic)
Answer:
Extrinsic Homeostatic Regulation
Explanation:
Extrinsic homeostatic regulation requires input from nervous system or endocrine system. The skeletal muscles are independent on the nervous and endocrine system, so therefore the homeostatic regulation is extrinsic.

name the main nitrogen-containing compound found both in plants and in animals
Answer:
Soil contains nitrifying bacteria that are crucial in converting nitrogenous wastes of dead and decaying matter of plants and animals to ammonia.
The most redox potential of soil nitrogen, ammonia, is transformed into its most oxidized form, nitrate, by nitrifying bacteria. By preventing soil nitrogen losses from leaching and nitrate denitrification, this is crucial for the function of the soil ecosystem.
What nitrogen compound found in plants and animals?The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals. The ammonia is subsequently changed into compounds that include ammonium. This is how the formation of ammonium compounds is aided by animals and plants.
Nitrification, which turns ammonia into nitrite and then nitrate, is a vital stage in the worldwide nitrogen cycle. Only prokaryotes perform aerobic nitrification, which makes up the majority of the process.
Therefore, The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals.

what is trait in psychology
Answer:
A trait is marked by the tendency to act, think, and feel in a certain way—over time and across situations. Terms such as disposition, construct, dimension, and personality variable have very similar meanings and psychologists often use them interchangeably.
A trait can be thought of as a relatively stable characteristic that causes individuals to behave in certain ways. The trait approach to personality is one of the major theoretical areas in the study of personality. The trait theory suggests that individual personalities are composed of these broad dispositions.

The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment:
**Written Response** What can they conclude from this experiment? Why?
Answer:
I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it
and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far
but in this condition the size can affect the ball distance it also depends on how much you give to it
