Q

why do cell need to diffuse materials and how is area:volume ratios related to cell diffusing material and how does it affect it talk about size and growth and what does the equation equal

A

cells diffuse oxygen because they need them inside them and around the inside of them and when cells grow the volume increases faster then the area making big cell not get filled up with materials quick enough the equation=area divided by volume

Q

what is the equation of aerobic respiration and anaerobic respiration

A

Q

how is yeast used in baking

A

Yeast is used in baking to help rise the bread because when it respirates it creates carbon dioxide (air bubbles in bread)

Q

describe how a growth curve diagram would look like for yeast in baking (In detail)

A

at first the growth line will not be very steep but then gets steeper because the population is growing so more yeast reproduce then the steep line gets less steep because Glucose(sugar) starts to run out finally the line become level because the population stop growing

25
what kingdom are bacteria from and what are its cell parts
belongs in the Prokaryotes kingdom cell parts include: flagellum slime capsule chromosome cell membrane cell wall cytoplasm
26
what is the function of this bacteria cell part flagellum
tail for Movement
27
what is the function of this bacteria cell part chromosome
a circular shaped chromosome made of DNA witch controls the cell
28
what is the function of this bacteria cell part cell wall
gives the cell its shape and provides protection
29
what is the function of this bacteria cell part cell membrane
controls what enters and leaves the cell
30
what is the function of this bacteria cell part cytoplasm
jelly like substance bacteria cytoplasm witch is where chemical reaction happen
31
what is the function of this bacteria cell part slime capsule
a outer layer that stops cell from drying out
32
what are the steps in making a pie chart from data step by step
1) add together all the data 2) do 360 divided by the total of data witch would equal to the degree of one piece of data 3) times degree of one piece of data to the actual data round some number if needed 4) now with the degree figured out draw the pie chart
33
what is the function of this protoctists cell part cytoplasm
jelly like substance where chemical reaction happen
34
what is the function of this protoctists cell part vacuole
storage area for food
35
what is the function of this protoctists cell part cillia
Cilia hair like structure that helps protoctists move, feed, and sense their environment.
36
what is the function of this protoctists cell part pseudopods
Pseudopods are extensions of the cell used for movement and feeding
37
what is the equation used in photosynthesis
carbon dioxide+water=glucose+oxygen
38
what is the equation used in respiration
Glucose+Oxygen→Carbon Dioxide+Water+Energy
39
what is the equation used in combustion
Hydrocarbon+Oxygen→Carbon Dioxide+Water+Energy
40
describe how algae make their own food and the importance of it
algae make their own food by photosynthesis This process is important for the ecosystem as it decreases the concentration of carbon dioxide in the atmosphere
41
say the names of job in a food chain in order and what they do
Producers: usually plants or algae that uses photosynthesis. Primary Consumers: eat producers. Secondary Consumers: eat primary consumers. Tertiary Consumers: eat secondary consumers. Decomposers: Organisms like bacteria and fungi break down dead organic matter
42
give example of decomposer and why are they important
fungi or bacteria decomposers are important because they break down dead matter, recycle nutrients, and enrich soil,
43
describe the basic features found on the carbon cycle
1)Carbon stored in the atmosphere, oceans, soil, 2)respiration release CO₂. 3)Decomposers return carbon to the soil and atmosphere. 4)Burning fossil fuels releases CO₂. 5)Oceans absorb atmospheric CO₂. 6)Plants convert CO₂ into glucose.
44
what did doctors wear in the 17th century to protect themself from the plague
the "beak" is filled with herbs to keep "bad air" away the long cloak, boots, gloves and mask were to not let "bad air" to reach their body
45
what was some ideas for treatment and causes for the black death
Ideas for treatment: Bloodletting Herbal Remedies Quarantine Prayers Ideas for causes: Bad Air Divine Punishment Astrology Contagion
