The cell membrane is selectively permeable, allowing only certain substances to pass through. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion.
<span>Homologous structures refer to structures that have similar characteristics in terms of morphology, anatomy, genetics, and embryology yet still different when their functions are concerned. On the other hand, analogous structures are those organisms that have similar lifestyle because they live in the same habitat yet they belong in different groups.</span>
Answer:
10 m/s/s or m/s²
Explanation:
Acceleration can be calculated by using the formula;
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
In other terms, acceleration (a) can be represented as ∆V/t.
According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:
a = 30 - 10/2
a = 20/2
a = 10m/s².
DNA profile is a forensic technique in criminal investigations. It is used to identify the origin of a DNA sample at a crime scene (example: from blood or hair) to DNA samples taken from suspects.
