The correct answers are:
- Decrease in rainfall in the Mojave desert;
The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.
- Decrease in runoff that flows into Mojave Lake;
If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.
- Increase in blocked streams that flow into Mojave Lake;
Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
Answer:
Erythrocytes is the answer
The Precambrian eon is separated from the Phanerozoic eon in the fossil record because of the sudden appearance of organisms.
Explanation:
Precambrian eon is the initial existence on earth that can be predicted by the study of rocks and remaining of fossils. It has been seen as the existence of skeleton in this era, before this era no such things has been observed, even the development of sexual reproduction.
The Phanerozoic era comes after the Precambrian era, more advanced kinds of fossils of animals had been observed in this era. Phanerozoic era period of life on earth. Large organisms sudden appearance are seen in the Phanerozoic era i.e. First dinosaurs, mammals, fishes, angiosperms,first vertebrates etc.
First of all - ecological interactions in the ecosystem indicates how species interact with each other and species interactions in the system include:
- competition,
- predation,
- camouflage
- mimicry
<span>In ecological competitions:</span>
- intraspecific competitions are an interaction where individual members of the same species compete for the same resources
- interspecific competitions are about which individual members of a different species compete for the same resources.

The options provided for the question above are as follows:
A. Respiratory tract illnesses
B. Skin infection
C. Acute infectious diaherea

Respiratory tract illnesses account for the majority of sickness that occur in child care settings. Such infection include those that affect the lower and the upper respiratory tracts; examples include: otitis media, sinusitis, bronchiolitis, pneumonia, etc. Children who attend out of home child care has greater risk of contacting these diseases.
