The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
Developmental dysfunctionGender imbalancesToxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

this is for my plant systems class
Answer:
Use natural rather than synthetic methods to control pests.
Explanation:
Integrated Pest Management (IPM) encompasses a variety of techniques used to maintain an acceptable level of pests in a given environment. that limits use of pesticides and maintains soil nutrients for future crops. Its four components are prevention, avoidance, monitoring, and suppression.These practices rely on natural efforts first

One of the roles of ecological succession is to encourage biodiversity in a habitat. Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat A)is destroyed B)remains the same C)undergoes change D)is relocated
Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat undergoes change. Thus C is the correct option.
What is ecological succession?Ecological succession is defined as the process through which the mix of species and habitat in an area changes over time. Gradually these communities replace one another until a climax community like a mature forest is reached, or until a disturbance, like a fire, occurs.
There are two major types of ecological succession namely primary succession and secondary succession. Primary succession occurs when a new patch of land is formed or exposed for the first time.
Secondary succession occurs when a climax community or intermediate community is impacted by a disturbance.

Choose the stage that best matches the description given.
In warm, humid climates, only dry bones would exist at this stage.
Day 1
Day 2
After day 50
Days 3-17
Days 26-43
Days 18-25
In order for an organism to decompose to the point that only dry bones will remain, it is estimated that in warm and humid environments the process will take roughly three weeks, In which case the options of Days 26-43 as well as after day 50 are correct.
Decomposition is what happens to any dead organic material. Decomposition is when the organic material is broken down into smaller compounds, organic or not. This process is affected by a variety of conditions including:
TemperatureHumidityPresence and species of insectsElements to which the material is exposedand so on. Each of these factors can greatly impact how fast something will decompose.
The question at hand gives us the conditions for the fastest decomposition, given that this process is accelerated in warm and humid conditions. When in these conditions, it is estimated that an organism can take a minimum of three weeks to reach the stage in which all that is left is the skeleton (dry bones).
Three weeks consists of 21 days, however, option 6 that states "Days 18-25" is not being included given that during days 18-21, elements other than bones may still be present. For this reason, the correct answer is any day after day 21, that is, days 22-50+. Therefore, options 5 and 3 can both be considered correct as in those days only dry bones will remain.

Which type of isolation is being described: Yellow butterflies breed during the summer season while red butterflies breed during the winter season, because of this, they cannot interbreed
temporal isolation
geographic isolation
behavioral isolation
By stating that "Yellow butterflies breed during the summer season while red butterflies breed during the winter season" we are referencing a form of temporal isolation.
Temporal isolation is one of the limiting factors for sexual reproduction between closely related species. Temporal isolation refers to the situation in which two closely related species cannot interact sexually with one another due to the timing of their respective mating events.
The question states that the yellow butterflies will breed during the summer season, whilst the red butterflies breed during the winter. Normally, species like this are closely related enough to allow interspecies breeding to take place and create a new species or simply diversify the existing ones. However, due to the distinct timing of the breeding cycles for each butterfly, they will not be able to breed with one another, which is a prime example of temporal isolation.

Black fur (B) is dominant to white fur. Soft fur (S) is dominant to rough fur. What is probability that the
offspring will have white color and rough fur?
Answer:
A) 1/16
Explanation:
Because both white fur and rough fur are recessive traits, you need all genes shown to also be recessive. If a single trait is dominant, then it will be expressed instead of a recessive gene. Because there is only one square out of sixteen that is all lowercase, the chance of having both recessive traits (White fur and Rough fur) is 1/16.
This is the equation for the thermite reaction:
Fe2O3 + 2Al = Al2O3 + 2Fe
You know the charge on the Al and O ions because you know how many electrons each atoms "wants" to give or take by looking at their position on the periodic table (and because it was listed on the cards). Fe is element 26, iron, in the middle of the periodic table. Since it forms Fe2

O3
3
, what charge does the Fe ion have?
The charge of Fe in Fe₂O₃ is +3.
Let's consider the equation for the thermite reaction:
Fe₂O₃ + 2 Al ⇒ Al₂O₃ + 2 Fe
One of the reactants is ferric oxide, we can calculate the charge of Fe in Fe₂O₃ considering that:
The sum of the charges of the atoms is equal to the charge of the compound.The charge of a neutral compound is 0.The charge of O in oxides is -2.The charge of Fe in Fe₂O₃ is:

When muscle cells run out of____________, they resort to lactic acid fermentation for a supply of energy. A. Carbon Dioxide B. Oxygen
Answer:
B oxygen
Explanation:
When your body runs out of oxygen, or your other systems can't deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
Lactic acid fermentation is the energy source used by muscle cells when their supply of oxygen runs low.
What is muscle cell?A muscle cell is sometimes known as a myocyte because smooth muscle cells and cardiac muscle cells are both very small cells. The long, threadlike cells of skeletal muscle with many nuclei are known as muscle fibers. Muscle cells are derived from myoblasts, which are embryonic progenitor cells.The cytoplasm and cell membrane of a muscle cell are known respectively as sarcoplasm and sarcolemma. The sarcoplasm contains myoglobin, which is a site for storing oxygen, and glycogen in the form of granules in the cytosol, which is an energy source.When your body runs out of oxygen or when your other systems are unable to transfer oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead of oxygen.To learn more about muscle cell refer to:

how are active faults and inactive faults similar
Answer:
Active faults are structure along which we expect displacement to occur. By definition, since a shallow earthquake is a process that produces displacement across a fault, all shallow earthquakes occur on active faults. Inactive faults are structures that we can identify, but which do no have earthquakes.

Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found on the cards. You can use the cards to figure out the formula by making as many copies of the cards as necessary to get them to line up exactly equally.
Example:
Na__Cl___
The chemical formula is NaCl, so you would place a 1 in the box for both Na and Cl.
A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.
