It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

List one organism and describe all of its adaptations.
Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.
What is adaptation?
In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.
Adaptation involves molecular, physiological, morphological, and behavioral changes.
For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.
A good and easy to unsderstand example of adaptation is the cactus.
Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.
To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.
They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.As their leaves are not developed, their stems photosynthetize to produce organic compounds.
Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.
To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

Explain why flask #2 (yeast with glucose) produced more CO2 than flask #5 (yeast with flour). AND how did you know it produced more CO2?
Answer: Glucose
Explanation:
The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.
6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.
Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.

A group of students wants to study the structures of animals in the desert. One question they should ask is-
How long do the animals live?
Can you buy the animals in pet stores?
How do the animals satisfy their need for water?
How many offspring do the animals have?
Answer:
Jdjdjdj
Explanation:
Animals survive in deserts by living underground or resting in burrows during the heat of the day. Some creatures get the moisture they need from their food, so they don't need to drink much water, if any. Others live along the edges of deserts, where there are more plants and shelter.
Even though deserts don't get much rain, the desert is a habitat for some plants and animals. Each species has adapted to be able to live in a range of temperatures and without much water. ... Animals that live in deserts include lizards, geckos, toads, jackrabbits, camels, snakes, spiders and meerkats.
How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.

How does a fire help grasslands?
Choose all that apply
Answer:
In most grassland ecosystems, fire is the primary mode of decomposition
Explanation:
Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.
A fire helps grasslands through the following:
Keeps trees from overtaking the grasses.Preserve biodiversity.What is Fire?This is the visible aspect of combustion of fuel and other materials to produce heat and flame.

Describe the functions and organization of tissue systems in a seed plant.
Answer:
tissues is the protect outer covering of plants
Explanation:
Plants consist of many different types of cells that are organized into aggregates called tissues. Tissues are derived from specialized groups of dividing cells called meristems. Meristems are the source of cells and tissues and therefore they are not strictly speaking tissues themselves
Plants are multicellular eukaryotes with organized tissue and specialized organs with specific tasks.
What are the functions and organization of the tissue system in a seed plant?Plants are multicellular eukaryotes, and their tissue systems are made up of many cell types that serve distinct purposes. Meristematic tissue and permanent (or non-meristematic) tissue are the two main forms of plant tissue systems. Meristems, which are areas of plants that experience continuous cell division and expansion, are where the meristematic tissue's cells may be located. Meristematic tissue cells continue to divide and support plant growth despite being either undifferentiated or incompletely differentiated. Permanent tissue is made up of dormant plant cells, which are no longer actively dividing.Secondary tissues can be simple (made up of similar cell types) or complex (composed of different cell types). Dermal tissue is a simple tissue that covers the plant's exterior and regulates gas exchange. One example of a complex tissue is vascular tissue, which is composed of the specialized conducting tissues xylem and phloem.To learn more about the functions and organization of the tissue system in a seed plant, refer to https://brainly.com/question/17774097
