What characteristics do you think could be used to classify different kinds of single-celled organisms? Write your ideas here
Answer: flagellum, a plasma membrane and organelles.
Explanation: In that sense, it can be difficult to find traits that they all share. Still, Project Oceanography at the University of San Francisco indicates that single-celled organisms have a number of common characteristics, including the presence of flagellum, a plasma membrane and organelles.
Flagellum, a plasma membrane and organelles classify different kinds of single celled organism and prokaryotic organism.
What are the different features of prokaryotic cell ?Prokaryotic cell are single celled organism, do not have membrane bound organelles and its size varies from 0.2 μm – 2.0 μm.
Here the Cell wall is present but True Nucleus is absent, the cell wall is mainly involve in photosynthesis and provide protection to cell, the ribosomes are Smaller in size having 70s type and spherical in shape.
Circular DNA is present as genetic material in prokaryotes, Mitochondria is absent in prokaryotes, the reproduction usually occur by binary fission and some times it occurs through conjugation.

A student created a table to compare animal adaptations. Based on the table, which
animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.
Answer:
B
Explanation:
Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.
Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.
What is behavioral adaptation?The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.
Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

15. The elements in group_
are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
When resistant bacteria multiply, what do they pass on to the next generation?
Answer:
Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.
The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?
A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.
Answer:
I think the option C is correct
The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
What are the characteristics of Archaebacteria?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.
