The answer is a half-filled circle. 

In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.

How is a virus different from a bacterum?​
I am Lyosha [343]

(it would be helpful if you marked me as brainliest)  :)

Answer:

Viruses are tinier than bacteria. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.

What is a major difference between facilitated diffusion and active transport?
Novay_Z [31]

Answer:

Major difference between active transport and facilitated difusion is:

Active transport moves substances against the concentration gradient.

Facilitated diffusion moves molecules through the plasma membrane.

Explanation:

  • Active transport involves the transport of molecules against the concentration gradient.
  • Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
  • Facilitated diffusion do not require energy  but need some other molecule or carrier protein to transport the molecules across the membranes.
  • In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
