What are some of the functions of vascular tissue in seedless plants? (Choose all that apply)
provides structural support that allows some lycophytes to grow taller
transports water and minerals
transports food
produces food through photosynthesis
Answer:
Explanation:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.
What is vascular tissue?Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.
Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways
Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.
Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.
Therefore, the correct options are A, B and C.

Succession Interactive!
What is the difference between primary succession and
secondary succession?
Primary succession occurs in an area that is disrupted by a
fire or other natural disaster but secondary succession does
not.
Primary succession occurs after secondary succession.
Primary succession involves only plants but secondary
succession involves animals too.
Primary succession occurs in an area with no life and no soil
but secondary succession happens in an area where an
existing community was disrupted.
Answer:
Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.
Explanation:
Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.
- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.
- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.

Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe
Answer:
Infections are generated by pathogens, pathogens that generate a rare invasion triggering an extremely risky condition for the host, opportunistic infections are usually caused by highly pathogenic microorganisms with high resistance mechanisms and are really serious signs and symptoms.
Primary pathogen is one that colonizes in a primary way by forming a biofilm or a microbiological ecosystem.
The great difference between infection and infectious disease is that the infection is the presence of microorganisms that cooperate and live with the host without generating pathology, whereas infectious disease is when these microorganisms generate a pathology or condition in the host.
Explanation:
The pathogenesis are different stages that make up the ability of a microorganism to get sick, an example is prevotella parvula or treponema denticola that during pathogenesis they quickly invade the tissues due to their movements, in addition to the tissues such as the mucosa they generate an immune distraction that release toxins in different areas to the invasion.
These are pathogenicity mechanisms, that is, how the microorganism does to be able to invade the tissues in the most oppressive way.
Explain in a few sentences how the carbon, nitrogen, and phosphorus overlap. How do these cycles cross paths through earths spheres?
Answer:
Explanation:Energy flow and nutrient circulation are the major functions of the ecosystem.
Energy is lost as heat forever in terms of the usefulness of the system. On the other hand, nutrients of food matter never get used up. They can be recycled again and again indefinitely.
Carbon, hydrogen, oxygen, nitrogen and phosphorus as elements and compounds makeup 97% of the mass of our bodies and are more than 95% of the mass of all living organisms.
In addition to these, about 15 to 25 other elements are needed in some form for the survival and good health of plants and animals.
These elements or mineral nutrients are always in circulation moving from non-living to living and then back to the non-living components of the ecosystem in a more or less circular fashion.
This circular fashion is known as biogeochemical cycling (bio for living; geo for atmosphere).
Among the most important nutrient cycles are the carbon nutrient cycle and the nitrogen nutrient cycle.
There are many other nutrient cycles that are important in ecology, including a large number of trace mineral nutrient cycles.
Which process plays an important role in the cycling of both carbon and nitrogen? photosynthesis transpiration decomposition respiration
Answer: C
Explanation:
Decomposition plays a major process to cycle the carbon and nitrogen due to dead matter, hence option c is correct.
What is the cycling of carbon and nitrogen?The biogeochemical cycles of carbon and nitrogen are all in plants and animals when dies bacteria decompose it and release nitrogen and carbon into the soil.
They depict how the elements travel through the Earth's life and nonliving constituents. The elements of life—carbon, and nitrogen pass through living things and nonliving things alike without ever being consumed.
Nitrification is the process by which bacteria convert ammonium into nitrates. Then, the plants may take up nitrates. It is through assimilation that plants obtain nitrogen, roots take up nitrates from the soil.
Therefore decomposition is the main process for cycling of both carbon and nitrogen, hence option c is correct.

d. Protein is synthesized exclusively in the cytoplasm.
1) What two problems does the transfer of information from DNA to protein need to overcome?
a.
b.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
How to bring the information from the nuclear DNA to the place of protein synthesis? How to convert this DNA information into amino acids and then into proteins?Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
How to bring the information from the nuclear DNA to the place of protein synthesis?The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
How to convert this DNA information into amino acids and then into proteins?Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which a plant has started to grow. A non-germinating seed is usually dry and a new plant has not yet emerged. The data that she gathered are displayed in the graph. After Callie obtained her original results, she wanted to dig deeper. She determined that the germinating corn seed had utilized 100 molecules of glucose in the first few seconds that she performed the experiment. If these data are accurate, how many carbon dioxide molecules would Callie expect to have been released as a waste during this same amount of time? Explain how you arrived at your answer. The formula for cellular respiration is shown below. C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
This a written question and please keep it at 7th grade level
Answer:
I might be wrong but im guessing 600
Explanation:
Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

State the term used to describe an enzyme that functions within a cell.
Answer:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism
Explanation:
An intracellular enzymes can be referred to as endocyto enzymes. These are intracellular proteins that accomplish their function within the same cell that synthesized them. They can be either free in the cytosol or associated with an organelle -inside the organelle or fixated to it-.
--------------------------------------------
Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions. They have specific binding sites to substrate molecules and turn them into product molecules.
Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they share many properties with all polypeptides. One of these is that they have a limited temperature level at which they denaturalize.
According to the place where they accomplish their function, enzymes can be called
Plasm-specific enzymes ⇒ Their action field is the plasma ⇒ These are exportation proteins.Secreted or Exocyto enzymes ⇒ Their action field are tissues placed far away from where they were produced and released (for instance, the pancreas secretes and releases enzymes that accomplish their function in the duodene) ⇒ These are exportation proteins.Intracellular or Endocyto enzymes ⇒ All enzymes that accomplish their function within the same cell that synthesizes them ⇒ These are intracellular proteins.Within the cell, enzymes can be free in the cytosol, or fixated to an organelle.
Uniloculated enzymes ⇒ 100% cytosolic enzymes.Biloculated enzymes ⇒ They spend part of the time in the cytosol and part in organelles.--------------------------------------------------------
