Describe the nervous response pathway when you taste something bad and spit it out. Using these keywords: stimulus, chemical receptor, sensory neurone, relay neurone, motor neurone, muscles, response, electrical impulse, chemicals
Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.
Explanation:
The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain. The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.
A major movement in the forest industry is _____.
A. Paper reduction
B. Slash and burn
C. Recycling
D. Reforestation
Answer:
D. Reforestation
Explanation:
Reforestation is a natural or intentional way of restoring existing forests and woodlands by restocking it after they have been depleted through deforestation. Forest industry makes use of forest product for production this includes log, paper and pulp production. Ability to restock after felling of this tree for product making helps continuation.
Reforestation helps to rectify the effects of deforestation and this helps to improve our health in turn by absorbing pollution and dust from the air.

Explanation:
Identical, or monozygotic, twins develop from a single egg fertilized by a single sperm. Monozygotic twins are genetically identical because they originate from a single zygote that split into two. Caroline Lost and her colleagues examined nine measures of social, behavioral, and cognitive ability in 1000 pairs of both male and female identical twins. Their study found that pairs of male twins tended to be more alike in their prosocial behavior, peer problems, and verbal ability scores than pairs of female twins. Which statement explains this observation?
Answer:
Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes
Explanation:
In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.

Coin tosses can demonstrate the effects of genetic drift. Imagine that heads and tails are two alleles in a population. Consider each coin toss to represent a member of the population. Write down the statements that describes the effect.
Answer:
Smaller populations have a greater chance of having one allele expressed disproportionately.
Explanation:
Genetic drift is defined as the a change in how frequently a gene allele occurs in a given population as a result of random sampling.
This random sampling is similar to having a coin toss that gives heads or tails.
Genetic drift has the tendency of making smaller populations have a greater chance of having one allele expressed disproportionately.
This is because when individuals in a small population mate there is a greater probability that an evolution will have more far reaching effects.
In a large population the effect will be less pronounced.

Unstained cells have very little contrast. What single adjustment could you make to your microscope that would make cells easier to see at the same time while reducing the evaporation of your sample?
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.
Which statement best describes the role of the nucleus in a cell?

O
Answer:
The boss at a factory gives out orders and directions.
Explanation:
The nucleus is an organelle that is enclosed by nuclear membrane and carry genetic material in eukaryotic cells.
The role of nucleus is to monitor and control the functioning of different activities such as growth and metabolism of the cell and also transfers the hereditary information. Likewise boss of a factory gives out orders and directions to regulate the factory properly.
Hence, the correct option is "The boss at a factory gives out orders and directions."

Explanation:
Describe how you could use a globe and your hand to model the path of a global convection current in the atmosphere.
Answer and Explanation:
The process of transmission of heat due to the movement of molecules in the fluid is called convection. Convection also takes place on a global scale. At the equator, warm and less dense air tends to flow and rise towards the poles. Then denser, cooler air sinks and flow back towards the poles. Due to the rotation of earth rising warm air from the poles does not make it all the mode towards the pole. The combination of the earth’s rotation and global convection makes a series of wind patterns known as convection cells. The earth's rotation also alters the airflow pathway, which causes the wind’s path to be curved as it travels between the equator and poles. In the southern hemisphere, winds turn to the left and move anticlockwise around a high-pressure centre, while in the northern hemisphere, winds turn to the right and move clockwise around a high-pressure centre. The twisting of air currents, due to the rotation of the earth is termed as Coriolis effect. Due to this effect, winds turn to the left in the southern hemisphere. In the northern hemisphere, winds turn to the right.
Identify the relationship described below:
Killer whales, also known as orcas, hunt and eat numerous other organisms — more than 140 species. However, orcas themselves are not hunted by any other organism. In other words, they are at the top of the food chain.
Group of answer choices
Mutualism
Parasitism
Commensalism
Competition
Predator-Prey
hi :)
The relationship described is predator-prey.
The orca is hunting and eating other organisms, which is known as a predator-prey relationship.
In case you need help with any more of these-
Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.
Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.
Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.
Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.

the cell cycle in the proper
order:
a. Anaphase
b. Cytokinesis
C. G2
d. Telophase
e. G1
f. Prophase
8. S
h. Metaphase
The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
What is the cell cycle?Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).
In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.
Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.
Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.
