Answer:
1/4 suffer from hemophilia
1/4 are heterozygous
Explanation:
So since they are normal but their son isn't it is assumed that the mom is the carrier since the dad has to be X^HY
X^HY x X^HX^h
Set up a pedigree
X^HX^H X^HX^h
X^HY X^hY
1/4 suffer from hemophilia (X^h)
1/4 are heterozygous (X^HX^h)
Answer:
Photosynthesis and respiration are similar in that they both produce ATP via an electron transport chain, biochemists and ATP synthase. In photosynthesis, ATP is produced in the light reactions by photo-phosphorylation through an electron transport chain, biochemists and ATP synthase in chloroplasts.
Explanation:
C. Diffusion.
The particles move WITH the concentration gradient
The autonomic nervous system is the one that pertains to sympathetic vs parasympathetic. The autonomic nervous system has three divisions: the enteric nervous system, the sympathetic nervous system, and the parasympathetic nervous system.
Sympathetic is the nervous system responsible for your “fight or flight” responses in times of emergencies. It controls the body’s responses to stress, injuries, or perceived threats.
Parasympathetic is the nervous system responsible for your “rest and digest” responses in times of non-emergencies. It controls the body’s responses at rest and helps your body regulate its normal daily organ functions.
One way to remember how to distinguish between the two is to associate the beginning letters of the words with their corresponding attributes.
The sympathetic nervous system kicks in during times of stress, and the parasympathetic nervous system kicks in during times of peace.
Of course, there is much more to both nervous systems than that so let’s look a little bit closer at both.

The first person to discover and accurately describe microbes was the amateur microscopist Antony van Leeuwenhoek (1632 - 1723) of Delft, Holland. He earned his living as a draper and haberdasher but spent much of his spare time constructing simple microscopes composed of double convex glass lenses held between two silver plates. </span>His microscopes could magnify 50 to 300 times and he may have illuminated his liquid specimens by placing them between two pieces of glass and shining light on them at a 45 degree angle to the specimen plane.
From<span> 1673, He sent detailed letters describing his discoveries to the Royal Society of London and it is clear from his descriptions that he saw both protozoa and bacteria.</span>
