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
Answers
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.

Under ideal laboratory conditions the rate of growth of bacteria is proportional to the size of the population at time tt. Suppose that 21002100 bacteria are present initially and that 42004200 are present 1 hour later. How many bacteria are there at the end of 55 hours?
Answers
Answer:
The amount of bacteria that are there at the end of 55 hours is 2310231000
Explanation:
From the description in the question, the bacteria's population size doubles per hour;
Within 1 hour = 21002100 × 2 = 42004200
Thus
After 1 hr ⇒ 42004200
55 hrs ⇒ ?
? = 55 × 42004200 = 2310231000
The amount of bacteria that are there at the end of 55 hours is 2310231000

Consider the food chain grasshopper mouse snakes hawks. If snakes go extinct what will happen to the food chain
Answers
Answer:
This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.
Answer:
Lack of mice
Explanation:
If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.
A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.
What is the independent variable in this experiment?
Answers
Answer:
The amount of light they receive.
Explanation:
In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.
The independent variable in this experiment is the amount of light received by each plant.
What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.learn more about independent variable here:

In a typical mammalian cell, what is the average percentage of total cell weight for protein and dna?
Answers
Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).
Explanation:
A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.
According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.
The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Suppose a cell culture of 1,000 cells is grown, in which the cells cycle every 24 hours. For a single cell, it takes about two hours from the formation of the dissolution of the nuclear envelope to the separation of two daughter cells.
Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?
A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B) There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C) There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D) There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
Answers
Answer:
The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.

much faster than they passed through the artificial membrane in this study
Which of the following statements best explains this finding?"
a) Actual cell membranes have a much thicker phospholipid bilayer than the artificial
membrane does
b) Actual cell membranes have a variety of proteins embedded in the membrane that are
absent in the artificial membrane
c) Hydrophobic substances spend more time between the two layers of phospholipid in
