Answer: A and B
Explanation:
Monosynaptic reflex arc consists of only two neurons, one motor neuron and one sensory neuron. Monosynaptic means the presence of a single synapse of chemicals. Monosynaptic reflex Arc simple reflection that involves transferring input from the sensory neuron to the correct motor neuron through a single synapse in the spinal cord.
For example: the action of knee-je.rk reflex.
As the A refers to sensory neuron and B refers to motor neuron, sysnapse between A and B is a part of Monosynaptic reflex arc .
D) All of these
Reason: All of these could be used as an alternative energy resource to help minimize air
pollution in this community.
Solar energy can be captured with solar panels and used to produce electrical energy or
to heat systems directly. Wind energy can be captured using wind turbines, which turn
generators to produce electricity. Hydroelectric energy can be produced by using the
energy of running water to turn generators.
Although all types of alternative energy resources have various advantages and
disadvantages, these three all share the advantage of not producing air pollution
Hope this helped. :)
<u>Answer:</u>
<em>Dark rich organic material formed as a top layer in soil from the decayed remains of plants and animals is called humus. </em>
<u>Explanation:</u>
When dead parts of plants and animals are deposited in soil the <em>decomposing bacteria present in the soil act on these remains and break them down. </em>
Plant and animal bodies contain organic compounds which are broken down into inorganic nutrients by the decomposers. These nutrients are taken up by producers and the nutrients restart their journey in the food chain.
<em>Humus is identified by its rich dark color. The amount of humus decides how fertile the soil is. More the humus content fertile is the soil. </em>
During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell. Mitosis has the following phases: prophase, metaphase, anaphase and telophase.
The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.
Answer: Producers
Explanation:
The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.
They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).
Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).
Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.
