Plz help with my work I really stuck on this
jek_recluse [69]
Question 1:
Basically, producers are things like plants the are the first source of food. Primary consumers are the first to eat the producers (like small fish, insects, etc) Secondary consumers (foxes, larger fish, etc) consume the primary consumers, and tertiary consumers (sharks, humans, whales, etc.) consume the secondary consumers. Decomposers (fungi, bacteria, etc) like the name suggests decompose rests of food and organisms and send the nutrients back into the earth.

Questions 2&3:
An autotroph is an organism that produces its own food (like plants do through photosynthesis) and a heterotroph is an organism that cannot produce its own food and has to seek out other sources of food.

Question 4:
Grass, Dragonfly, Trout, human

Question 5:
Bean plant, rabbit, fox, bacteria

Questions 6&7:
They are a little harder to explain in text form but hopefully my explanations can help you figure out the answer yourself.

Hope this helped!

How many grams of solute are needed to make 250 mL of a 2.055 M NaCl solution?
Veronika [31]

Answer:

30grams

Explanation:

To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;

M = n÷ V

Where; M= Molarity or Molar concentration = 2.055M

n= number of moles= ?

V= Volume = 250mL

Volume in L is 250/1000 = 0.250L

n= M × V

n= 2.055 × 0.250

n= 0.51375moles

The mass is calculated using :

Mole (n) = mass (m) / molar mass (MM)

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

Mass = molar mass × mole

Mass = 58.5 × 0.51375

Mass = 30.0543

Therefore, the mass is 30grams

In what way does healing of cartilage occur in adults (a person who has stopped growing)
Elden [556K]

In the adults, the growth rate slows with age. The healing mechanism of the different cells if damaged is different than that of the younger ones. If a cartilage is damage in the adults, the chondrocytes which are still surviving secrete more extracellular matrix in order to heal the damaged cartilage. The chondrocytes cells are present in the cartilage, and they function to maintain the cellular matrix of the cartilage.
