Answer:
the directionality problem
Explanation:
In directionality problems, there are two variables and when these two variables are co-related then it becomes impossible to decide which variable is the cause of the particular problem and which variable is the effect of the problem.
So here there are two variables depression and insomnia but scientists can not determine that out of insomnia and depression which is the cause of the problem and which is the effect of the problem so it is unclear that whether the depression causes insomnia or the lack of sleep causes depression. Therefore this is an example of directionality problem
.
Answer:
Offspring of two different true-breeding varieties are called hybrids.
Explanation:
Pure-breeding plants are plants that self pollinate for many generations and all its offspring had the same features as the parents, generation after generation.
When Mendel cross pollinate this pure-breeding plants with contrasting traits, the offspring is called hybrids because they resulted from a cross between two pure-breeding plants with contrasting traits.
<span>FLACC SCALE
</span><span>he FLACC Scale (face, legs,
activity, cry, and consolability) is used to measure pain for children
between the ages of 2 months and 7 years. The Braden scale is used to
predict pressure sore risk. The FACES Scale is used to assess pain in
older children using a series of faces, ranging from a happy face to a
crying face. APGAR score is done at birth to assess how well the baby
tolerated the birthing process</span>
Rock Mineral
Explanation:
Rock minerals are naturally occurring inorganic solids with a definite chemical composition and an orderly arrangement of atoms.
Minerals forms as a result of combination of different elements.
The minerals makes up rocks. A rock is an aggregate of minerals.
- They are naturally occurring: minerals are not formed in the laboratory through a synthetic process.
- The are inorganic: not formed by living organisms.
- Solids: minerals are in the solid phase of matter
- definite chemical composition: they are compounds and not mixtures.
- Orderly arrangement of atoms: they are crystalline
