OA. limiting the number of fish that can be caught in the river.
OB. requiring the company to release its wastewater into a local pond.
a
OC. requiring the factory to pump its water to a treatment plant.
OD. requiring people to avoid boating and fishing on the river.
Answer:
OC
Explanation:
In OA, by limiting the number of fish caught does not have any connection with the waste released. Its totally different idea.
In OB, pond is still a part of environment. Pond too have its own habitat and no mater if the company release less waste or too much waste, it still affect the environment.
In OD, by avoiding boating we dont have much to do. Still there is no correlation with redcing the waste released.

How does the binding affinity of a transcription factor to DNA affect the efficiency of Protein Synthesis?
Answer:
The addition of transcription factor-binding sites could affect relative DNA replication efficiency in a number of ways. Each added site could produce an additive increase in replication efficiency, or one of the added sites could be responsible for all of the observed increase in RRE.
describe photosynthesis
Answer: photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds
Explanation:
Photosynthesis is the process through which plants make their own food using Sunlight, Groundwater and Carbon Dioxide.
Explanation:In the Chloroplast of plant cell, there is a green pigment known as chlorophyll. The chlorophyll captures the sunlight and with the help of soil water and Carbon Dioxide present in environment, it creates Carbohydrate which is Glucose (a form of sugar).
The above mechanism can be compressed in a single reaction given below.

Cedar waxwings are one species of bird that is adapted to
withstand our cold winters. Bird watchers in Barrie provide
cedar waxwings with seeds at birdfeeders during winter
months. wum
(a) Would the seeds alter the carrying capacity of the
ecosystem? Explain.
(b) Provide a hypothesis that explains why bird watchers have
noted an increase in the falcon population in recent years.
The process of adding or removing the food supply (seeds) in an ecosystem would alter its carrying capacity.
What do you mean by Carrying capacity?Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat to live. Every habitat has a fixed carrying capacity.
When the winter period comes, it decreases the number of seeds of cedar waxwings. At this time seeds undergo to dormant stage due to the freezing temperature of the winter, hence they can not be reproduced at this point.
In spite of this, offering seeds to the bird feeders during winter can be adequate for the reduction in the food supply of these birds.
It can assist them with sufficient food resources which allows them to get through the winter season. Hence, increasing the carrying capacity for the cedar waxwings in the ecosystem.
Therefore, it is well described above.

if the original cell is dead, does it stay their or does it disappear after mitosis?
Answer:
It disappears. The cell disappears because it can no longer divide if it dies.
if the original cell is dead, the cell is almost dead too. It has no ability to divide itself too.
What are the types of cell division ?There are two types of division one is mitosis and the other one is meiosis.
Once mitosis completes, the cell has 2 groups of 46 chromosomes, each enclosed by their own nuclear membrane. The cell later splits in 2 by process called cytokinesis and creates two clones of the original cell each with 46 mono valent chromosomes.
Mitosis is a nuclear division in which duplicated chromosomes segregates and distributed into daughter nuclei. The cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

Identify the sedimentary rock composed of halite and explain how this rock is usually formed.
The sedimentary rock composed of halite is known as rock salt, and it is usually formed by the process of evaporation, and rock salt is formed in environments where there is a high concentration of salt in water.
What is rock salt?Rock salt is formed in environments where there is a high concentration of salt in water, such as salt lakes, shallow seas, or salt pans, and when the water in these environments evaporates due to high temperatures and low precipitation, the dissolved salt in the water is left behind and forms deposits. These deposits can be buried by sediment over time and eventually become compacted and cemented to form rock salt. Rock salt is made up almost entirely of the mineral halite, which is composed of sodium and chlorine ions.
Hence, The sedimentary rock composed of halite is known as rock salt. It is usually formed by the process of evaporation.

Determine the stability of each ecosystem. 1. an ecosystem with populations that mate with unrelated species. 2. an ecosystem that has very few species at every trophic level. 3. an ecosystem with populations that mate with only related species. 4. an ecosystem that has many species at every trophic level. Less Stable More Stable
The number of species and the mating patterns of species in an ecosystem will make it either more or less stable.
What is the stability of an ecosystem?The stability of an ecosystem refers to the ability of that ecosystem to remain relatively unchanged in the composition of both biotic and abiotic factors over a long period of time.
The stability of an ecosystem depends on the changes that occurs in the ecosystem.
Considering the above situations;
an ecosystem with populations that mate with unrelated species will be less stable.an ecosystem that has very few species at every trophic level will be less stable.an ecosystem with populations that mate with only related species will be more stablean ecosystem that has many species at every trophic level will be more stableTherefore, the number of species and the mating patterns of species in an ecosystem affects the stability of the ecosystem.
