What is the most important property of water for protecting fish in a shallow pond on a hot summer day

Biology
1 answer:
noname [10]3 years ago
3 0
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 normal sequence of genes along a hypothetical chromosome is ABC*DEFGH, where letters represent genes and the asterisk (*) re
Hunter-Best [27]

Answer:

The correct option is e

Explanation:

An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.

From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.

NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.

What are the two recognized means of preventing injury during electrical equipment operation?
baherus [9]
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.

Debora [2.8K]

Answer:

1. Light

2. production of large component from smaller components

Explanation:

In the given question, the meaning of the word Photo is light and the synthesis refers to the production and combining these words form photosynthesis. The literal meaning of photosynthesis will be the production of some compounds in the presence of light.

The word photosynthesis is used by the biologists to refer to a process taking place in the green plants which involve the light for the synthesis of energy-providing molecule glucose.

Thus, 1. The light and production of the large components are correct.
