Answer:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Yes because igneous rocks are made from lava that cools in or outside of a volcano and sedimentary rocks are simply made of sand rocks and other things that just stick together in layers and forms a rock. I don't know if I'm being clear though... Sorry I speak French but I hope I helped :)
Answer:
D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem
Explanation:
In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.
In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.
Answer:
It increases haemoglobin's affinity.
Explanation:
When CO binds to one heme molecule, the haemoglobin molecule becomes in a relaxed state and oxygen can bind so very easily.
The problem is not in the uptake of oxygen, it's with its delivery. The affinity for oxygen increases so much such that it becomes impossible to release and deliver the oxygen to tissues.
