Answer: B) ferns
Algae, liverworts and moss are examples of plants with no
real stems, leaves or roots and are also known as nonvascular plants. Plants
with true roots are known as vascular plants. Vascular plants have real roots, stems and leaves and contain vascular tissues.
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
Answer:
The answer is 306 m/s^2
Explanation:
F = m*a
We can rearrange this formula to get a = F / m.
The SI unit for mass is kilograms (kg).
The SI unit for acceleration is m/s^2.
There are 1000 grams in a kilogram.
7.20 g = 0.00720 kg
Force (2.20 N) / 0.00720 kg = 305.56 m/s^2
Accounting for Sig Figs, the answer is 306 m/s^2.
Gee, that's one fast bullet.
