They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.

Answers

Answer:

They are both made of one or more cells.

Explanation:

A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

One theory of early life on Earth states that the first life forms did not use oxygen for respiration and were unable to make their own food. Based on this theory, which types of organisms were most likely present? *
A. aerobic, autotrophic bacteria
B. anaerobic, autotrophic bacteria
C. aerobic, heterotrophic bacteria
D. anaerobic, heterotrophic bacteria

Answers

The theory of primitive life on Earth is fascinating, there are countless scientists who try to explain how life began on Earth, but to be able to answer how the first living beings were we need to know that.....

Oparin and Haldane hypothesis

The most widely accepted hypothesis about the origin of life today is the Oparin and Haldane hypothesis. According to this idea, the primitive Earth would be constituted by

AmmoniaHydrogenMethane and Water vapor,

which are constantly expelled by volcanic activities. The condensation of this water vapor gave rise to a cycle of rains, as these, upon reaching the still hot surface of the Earth, evaporate again, thus initiating a new cycle.

Through the action of the sun's ultraviolet radiation and constant electrical discharges, the elements present in the atmosphere began to react, giving rise to the first organic compounds, called amino acids. The rains carried these compounds to the primitive oceans, which formed when the Earth's surface cooled, allowing water to accumulate on the surface.

In primitive oceans, these amino acids joined together, forming protein-like compounds (proteinoids), and then, after further reactions, these gave rise to coacervates. These became more stable and complex, controlling their own chemical reactions and being able to self-duplicate, thus giving rise to the first living beings.

Heterotrophic and autotrophic hypotheses

Some authors believe that the first organisms would be heterotrophs. This was due to the fact that the first organisms were simple, lacking the structure to carry out a more complex biochemical process to obtain food, for example, photosynthesis. Thus, these organisms fed on simple organic matter, presenting as the end product of this process carbon dioxide (CO2) and alcohol (C2H5OH), that is, the first living organisms would be fermentors.

With this information, we can say that the first living being on the planet was anaerobic, heterotrophic bacteria.

D. anaerobic, heterotrophic bacteria

There have always been many theories about the origin of life on the planet, but this is the most acceptable among scientists, but it is necessary to know that they are not yet fully proven, so they continue as a theory.

a. True

Explanation:

Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.

The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.

Little brown bats are a species of bat in the genus Myotis. Little brown bats are extremely common in North America, where they roost in houses, buildings, or trees.

Given these terms related to bats, match the term to the level of biological organization.all little brown bats

Answers

Answer: population: The bat species of North America

community : a little brown bat

organism: bat

Explanation:

Here, the population of the bat resides in the North America in the houses, trees and buildings they hide in the caves in winters for hibernation. Inside the cave they form a bat community here the organism is bat. These bats are threatened in numbers due to white nose syndrome. The white nose syndrome is the fungal growth on the wings and muzzles of the bats. The fungus affects the bats during hibernation, when the bats trying to save their energy by reducing their metabolic rate. It is transferrable from one bat to another thus can infect the entire population of bat. It is a dangerous disease.

Charles Darwin not only proposed that species could change over time, but he also described a process by which these changes could occur. What was that process?

Answers

Answer:

Charles Darwin had a theory that states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

The theory of natural selection was proposed by Charles Darwin. Darwin postulated that species could change over time.

What is the theory of natural selection?

The adaption by organism according to the surrounding environment is natural selection. It drives evolution.

Individuals in a population vary naturally. It means they are all different in some ways.

This variation means that some individuals have traits that suit better to the environment as compared than others.

This causes the species to change over time.

Thus, the process by which these changes take place is natural selection.

In your own words, describe the gulags were after you watch the film.The Soviet Union pre-WWIIJoseph Stalin was born in Georgia, a country just south of Russia. He joined the Russian Bolshevik revolutionaries who were a group of people that followed communist ideals. Stalin led riots and strikes and raised money by robbing banks and committing other crimes. Soon Stalin became close to Vladimir Lenin (Soviet Russian Communist leader). In 1917, the Russian Revolution took place when the government led by the Tsars (royal family) was overthrown and the Bolsheviks came into power. Russia was now called the Soviet Union and Joseph Stalin was a major leader in government. After Lenin's death, Stalin took over as the dictator of the Soviet Union. Stalin decided that the country should move away from agriculture and become industrialized. He had factories built through the country. The Soviet government controlled the economy and took over all farms, limiting the amount of food. Stalin would not supply food in some areas of the country to starve those that he no longer wanted to live. Stalin was responsible for the deaths of over 20 million of his own people! Stalin had secret police who spied on people. He had anyone that did not agree with him killed. Stalin put anyone who could be seen as an enemy in the gulags (prison camps) without a trial, where they faced hard labor and terrible conditions.Stalin attempted to rewrite history books about himself, renamed cities in his name, put up numerous statues of himself, and had songs and art dedicated to him. Throughout his rule he ordered millions of people he thought were against him to be killed or put into slave labor camps. At the start of World War II, Stalin formed an alliance with Adolf Hitler and Germany. However, the Germans made a surprise attack on the Soviet Union in 1941. In order to fight off the Germans, Stalin joined the Allied countries. After World War II, Stalin set up governments in the Eastern European countries that the Soviet Union had "freed" from Germany. These governments were under control by the Soviet Union.
