If the mother is a carrier and the father is normal, the outcomes for potential children would be:
XH Xh
XH XHXH XHXh
Y XHY XhY
So let’s break these down
XHXH = will be a daughter (XX) with normal blood (HH)
XHXh = will be a daughter (XX) who is a carrier for hemophilia (Hh)
XHY = will be a son (XY) with normal blood (H)
XhY = will be a son (XY) with hemophilia (h)
Because this disease is inherited on the X chromosome, male offspring tend to either have it or not. They can’t be carriers because they only have one X chromosome. So the chances of having a son with hemophilia will be 50% cause the boys have a 50% chance of inheriting hemophilia.
On the other hand, daughters will either have normal blood or be carriers in this situation. So to answer the question, the chance a daughter of this couple would have of inheriting hemophilia is 0%. This only changes if their father has hemophilia. Then they will either be a carrier or will have hemophilia.
When you are preparing or handling food, there are certain precautions to be followed to keep the eatables hygienic.
While handling food, one should remove before prepping food. He/she cannot wear rings, except the plain band. Bracelets and watches don’t matter as they are physically contaminated.
Eating, Drinking, Smoking, and Chewing Gum or Tobacco is strongly prohibited in the cooking area. Small droplets of saliva can contain thousands of pathogens, therefore, avoid spitting while prepping or serving food. Items of jewelry like rings, bracelets, and watches could collect soil and it could obstruct routine cleanup. As a result, the jewelry could act as a reservoir of unhealthful organisms which may transfer to the food.<span>

Answer:
D) Light and Water
Explanation:
Using energy from light, plants chemically combine carbon dioxide and water to create glucose and oxygen. This process is called photosynthesis. Plants also absorb oxygen gas from the air. Like animals, plants need oxygen to respire.

Answer:
Amphibians lay eggs.
Explanation:
Amphibians include frogs, toads, and salamanders. They are vertebrates, so they have a bony skeleton. Most amphibians live part of their lives underwater and part on land. Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do. As the tadpoles grow, they develop legs and lungs that allow them to live on land (aka metamorphosis). Even after they change, amphibians still have soft moist skin, and nearly all of them have to live in damp places, so they don't dry out.
