Explanation:
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets.
Answer: Low oxygen content.
Explanation:
There are many dangers to the survival of fish in shallow water that depend on the properties of water.
1. The oxygen content drops during the winter and also in hot weather. Fish cannot survive without enough oxygen in the water.
2. High evaporation rates can drain the pond.
3. Fortunately, water has a high thermal mass, so overheating the water to the boiling point is not an issue.
Of the three reasons given, lack of oxygen is the most critical.

The correct answer is social support.
Social support refers to the actuality and perception that one is cared for, has support accessible from other individuals, and most importantly, that one is a part of a supportive social network.
The four kinds of social support are:
1. Emotional: Expressions of love, empathy, caring, and trust.
2. Informational: Suggestions, advice, and information.
3. Instrumental: Tangle assistance and service.
4. Appraisal: Information, which is beneficial for self-assessment.
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
