Answer:
The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.
Explanation:
The speed of the stream's current is 3.6 m/s.
The given parameters:
- distance between the two flags, d = 100 m
- time when it passed the first flag, t₁ = 2:15
- time when it passed the second flag, t₂ = 2:43
<h3>What is speed?</h3>
- The speed of an object describes the rate of change of an object's distance.
The change in the time of motion of the barrel is calculated as follows;
Δt = t₂ - t₁
Δt = 2:43 - 2:15
Δt = 2 min 43 s - 2 min 15 s
Δt = 43 s - 15 s
Δt = 28 s
The speed of the stream's current is calculated as follows;

Thus, the speed of the stream's current is 3.6 m/s.

The answer to the question is A
Answer:
These mutualistic relationships are typically characterized by benefits to both the fungi and the plant that host them, with both benefitting at the same time.
Explanation:
Mutualism relationships are often characterized by a beneficial relationship between organisms. If one party benefits and the other doesn't benefit or the other doesn't really need the relationship, then that is not a mutualistic one.
Fungi partner plants for mutual benefits where the plant benefits and also reward the fungi. Two ways are explained below:
1. Fungi that live within plant tissues, produce toxins that affect animals that feed on the plant so limiting grazing, this activity tends to make the plant not overgrazed and protects the plant tissues. In turn for this favor, the plant rewards the fungi with nutrients to aid their continuous survival.
2. Mycorrhiza is a type of fungi found in plant roots and they are fed with most especially carbohydrates. So as they grow in population and thrive well they also reward the plant with the capacity to take up more essential nutrients from the soil which is very important for plants productivity.
