How is a volvox different from the other protists?
Answer:
Volvox are protists that live in colonies, or groups of organisms living together. They are both autotrophs and heterotrophs. They use their eyespot to detect light when they undergo photosynthesis. They also have tails, or flagella, they use to move the colony.

What is formed by a group of cells and tissues that work together to carry oul a specific function? O cell O tissue O organ O organ system
Answer:
The answer is C: Organ
Explanation:
A single organ is made of tissue, which carries out a specific function, multiple organs carrying out multiple functions make them an organ system.
Organs are what is formed by a group of cells and tissues that work together to carry out a specific function.
LEVEL OF ORGANIZATION:
The level of organization of life describes the hierarchical pattern of life. Cell is the basic and fundamental unit of life, hence, the simplest. Cells form tissues, tissues form organs, organs form organ systems and systems form organisms.According to this question, a group of cells and tissues that work together to carry out a specific function is called organ.Learn more at: https://brainly.com/question/905358?referrer=searchResults
If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine?
Answer:
Explanation:
the base pair of adenine is thymine they are equal in amount in RNA so if 30% of the nucleotide in RNA is adenine so the percentage of thymine would also be equal to adenine that is 30%
If the DNA strand has 30% Adenine in its composition, it means that the same DNA strand has 30% thymine in its composition.
This is because:
DNA is composed of the nitrogenous bases Adenine, Thymine, Cytosine and Guanine.These nitrogenous bases were paired with each other.Adenine pairs with Thymina. While Cytosine pairs with Guanine.Therefore, the amount of Adenine and Thymine in a DNA must be equal. While the amount of Guanine and Cytosine must be equal.In this case, we can conclude that if the DNA has 30% of Adenine, it is mandatory that this same DNA has 30% of Thymine.

Choose 1 answer:
(Choice A)
A
Animals
(Choice B)
B
Bacteria
(Choice C)
C
Plants
(Choice D)
D
Fungi
Answer:
choice B
Explanation:
Bacteria are super small single-celled organisms that thrive in many environments.
Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.
What are Prokaryotes?A prokaryote is defined as a single-celled organism that lacks a nucleus and other membrane-bound organelles. Prokaryotes were classified within the kingdom Prokaryota.
Prokaryotic cells are described as single-celled microorganisms that are the earliest known on Earth which include bacteria and archaea. Photosynthetic prokaryotes include cyanobacteria that photosynthesize that have a single cell membrane and, therefore, all reactions occur within the cytoplasm.
Bacteria are examples of the prokaryotic cell type, some example is E. coli.
Thus, Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.
Answer:
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.
Within the protist kingdom, organisms have developed very similar structures that are used to move around the environment.
The protist kingdom is primarily comprised of very small, single-celled organisms. Among the vast number of organisms that make up this kingdom are algae and amoebas. Over the course of history, these organisms have evolved very similar means of mobility.
Within the protist kingdom, most of the organisms move with one of the structures:
CiliaPseudopodiaFlagellaThese three structures used by protist to move are very similar in that are all structural extensions on the exterior limit of a cell. Though clear differences exist in the number or other uses of these extensions, it is clear that all of the members of this kingdom have evolved similar means of mobility.

How is variation introduced into populations of asexual organisms such as bacteria and amoebas?
Answer:
In asexual reproduction an exact genetic copy of the parent organism is produced. Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.

The structure of jupiter and sun mostly made up of hydrogen and helium.
What are the characteristics of hydrogen and helium?Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.
It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.
The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.
