Answer:
1. Receptor (nociceptor).
2. Afferent neurons.
3. Spinal cord.
4. Motor neurons.
5. Efferent neuron (effector).
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).
5. According to a biomass pyramid, 50 mice will need 200 square meters of grass, if one mouse needs to eat four square meters of
grass to stay healthy.
O false
true
I will give out brainliest
Answer:
The statement is true.
Explanation:
As every single living organism, the mice also have their own unique requirements as to how much food they need to produce enough energy in order to stay healthy. Because the mice are small, warm-blooded, highly active, and have very fast metabolisms, they need a lot of food for their size.
If one mouse needs four square meters of grass to stay healthy, so if we want to find out how much grass is needed for more mice we just need to multiply the number of mice by the amount of grass needed for one mice. In this case, we have 50 mice:
4 x 50 = 200
We got 200 square meters of grass, meaning that that would be the amount/area of grass that will be enough to support the population of 50 mice.

Which of the following statements is true regarding individual III-5? Select all that apply. Select all that apply. Individual III-5 is male. Individual III-5 is female. Individual III-5 is affected by the genetic condition. Individual III-5 is not affected by the genetic condition. Individual III-5 is the proband.
Answer:
III-5 is male.
Individual III-5 is affected by the genetic condition.
Individual III-5 is the proband.
Explanation:
In human pedigrees, males are represented by squares while females are represented by circles. Individuals affected by the focus trait in human pedigrees are usually shaded, those that are carriers are half-shaded, while those that are not affected at all are not shaded in any form.
Thus, from the pedigree (see the attached image), III-5 individual is a male and affected by the genetic condition in focus.
Also, III-5 individual is a proband, because a proband is an individual that is first affected by a genetic trait in a family.

During which part of meiosis (meiosis I or meiosis II) do the two alleles of a gene separate? During which phase does the separation occur? (Assume no recombination.)
Answer:
meiosis 1, anaphase
Explanation:
Meiosis is a type of cell division that consists of two rounds of cell division known as Meiosis I and Meiosis II, and one round of DNA replication, thereby the resulting cells (gametes) contain half of the genetic material found in somatic (body) cells. Both Meiosis I and Meiosis II can be divided into the following phases: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. Alleles of a gene separate during the anaphase of Meiosis I (i.e., Anaphase I), because homologous chromosome pairs separate during this phase of the cell cycle.
Answer:
During the ANAPHASE of MEIOSIS I, IF there is no recombination, the two alleles of a gene separate
Explanation:
Meiosis is a process by which, from a diploid germ cell (2n), four daughter cells with a haploid chromosome number (n) are produced. Each daughter cell has half of the chromosomes of the original one. There are two phases in meiosis: the first one in which occurs a chromosome´s reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.
If there is no recombination or crossing-over between a locus and the centromere, during anaphase of meiosis I, occurs the separation of the alleles. One of the alleles migrate to one pole and the other migrates to the other pole .But if it occurs crossing-over, the allele separation occurs in the anaphase of meiosis II, when chromatids separate.What kinds of characters can you use to create a data matrix for estimating phylogenetic trees?

4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods
Explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually. Animalia Kingdom: Includes different phyla closely relates. The embryonary development of bilateral coelom animals makes a place for the division of two groups: protostomes and deuterostomes. Among protostomes might be mentioned the flatworms, annelids, mollusks, and arthropods. Protostomes show spiral initial segmentation, and the mouth develops as a first opening near the blastopore. Ecdysozoan Superphylum: Their bodies are covered by a cuticle that provides protection. They have a complete digestive system. They might reproduce sexually and asexually.Phylum Arthropoda: Invertebrates characterized for having an exoskeleton, a segmented body, and articulated appendixes. A very diverse group with many different characteristics.How many molecules of water are created when making a lipid?

Which of the following is NOT a
common source of air pollutants?
A. agriculture
B. burning yard waste in your back yard
C. driving a car
D. applying fertilizer granules to your yard
Application of fertilizer granules to the yard is not a common source of air pollutants.
What are air pollutants?The natural and artificial airborne components, which are released into the air resulting in air pollution are known as air pollutants. These are detrimental to health of human beings as well as the entire planet.
Agriculture is an essential sector, which contributes to air quality and environmental effects. The air pollutants from agriculture like hydrogen sulfide, ammonia, toxic organic components, particulate matter, and pesticides are contributing to human health issues.
Burning yard waste release harmful gases like carbon monoxide to the atmosphere contributing to health issues. While driving car, combustion of fuels takes place, which release air pollutants to the atmosphere.
The application of fertilizer granules to the yard is the common source of water pollutant as washing off of fertilizers into the water bodies results in water pollution, which is harmful to the aquatic species and affects the food chain associated with it.
Thus, the correct answer is option D.

In 3–5 sentences, compare and contrast the flow of matter and energy in each
trophic level for land-based ecosystems and marine ecosystems. How and why
are they similar, and how and why are they different? (4 points)
Answer:There is a fundamental difference in the way energy and matter flows through an ecosystem.Matter flows through the ecosystem in the form of the non-living nutrients essential to living organisms. When a living organism dies, nutrients are released back into the soil. These nutrients then are absorbed by plants, which are eaten by the herbivores. Matter, once again, is passed on. The herbivore is eaten by a carnivore (and matter is yet again transferred therein). Ultimately, when the carnivore dies, matter is returned back to the soil by the decomposers and the cycle repeats. So you see, matter is recycled in the ecosystem.Unlike matter, energy is not recycled through the system. A part of the energy is lost at each stage.

Using the Gizmo, create four energy paths to explain how the toaster could get its energy.
Answer and Explanation:
Energy is well-defined as the capacity to do work. Heat is the kind of energy. It is transmitted from the high-temperature object to the low-temperature object. When electricity runs over a wire, energy is transferred from one end of the wire towards another end. Electricity flow in the wire by electrons. When electricity flows, the electrons collide with one another and give off heat due to collision. Less collision of electrons produce less heat, and more collision of electrons produce more heat. When the toaster wire plugged into the electricity supply, electric energy began to flow through the wire—the electric current run over a series of filaments. The filaments are thin and connected. When electric energy flows through the filaments, they glow red hot and transfer the bread. The filaments are present on both sides of the toaster. So the bread cook from both sides at a similar time.
