Answer:
Motor neurons are activated and the muscles of your arm contract, moving your hand away from the sharp object. This occurs in a fraction of a second — before the signal has been relayed on to the brain — so you will have pulled your arm away before even becoming conscious of the pain.
This is called a motor reflex.

Which of the following is an example of an ecosystem service that would provide protection from a hurricane storm surge?
A lock and dam system
An intact coastal wetland
An energy-producing tidal barrage system
An offshore, deep-water fish farm
Answer: An intact coastal wetland
Explanation:
Hurricane storm surges results when the water level rises above normal as a result of a storm and therefore goes inland from the coast far deeper than it normally does.
Normally this can destroy things next to the coast by washing them away but some ecosystem services can provide protection against this such as an intact coastal wetland. Being intact, there are less chances of being washed away and as it is a wetland it is used to high levels of water and can even absorb some of the surge.

why is blood pressure an example of negative feedback?
Answer:
Regulation of blood pressure is an example of negative feedback. ... If blood pressure is too high, the heart rate decreases as the blood vessels increase in diameter ( vasodilation ), while the kidneys retain less water. These changes would cause the blood pressure to return to its normal range.

Two amino acids unite by forming a(n) bond between them and releasing a molecule of . The union of many amino acids forms a macromolecule called a .
Answer:
Protein/nucleic acid/Carbohydrates/lipid
The correct and most appropriate words to fill in the blanks are: peptide, water and protein.
An amino acid can be defined as a simple organic chemical compound that is made up of an acidic carboxyl group (COOH), a basic amino group ([tex]NH_2[/tex]), and a variable (unique) side chain group.
Generally, an amino acid is typically named after two (2) of its functional groups and these are:
An acidic carboxyl group (COOH): it acts like an acid.A basic amino group ([tex]NH_2[/tex]): it acts like a base.
Basically, a peptide bond is formed between two amino acids when they unite. Also, this chemical reaction lead to the release of a molecule of water.
Finally, the union of many amino acids forms a macromolecule called a protein.
In conclusion, protein is a macromolecule which is formed as a result of the union of many amino acids.

Which statement explains the role of genes in the process of inheriting a specific trait? Question 8 options: Genes are changed by the environment of a living thing and these changes effect the genes of the offspring. Genes in living things come together to make chromosomes which take information from offspring to parent. Genes absorb chemicals from the blood stream and carry them throughout the body of parents and offspring. Genes which are past from both parents carry the genetic material that determines inherited traits.
Answer:
Genes which are past from both parents carry the genetic material that determines inherited traits.

In 1851, Gregor Mendel, a young monk in Europe, formed the foundation of genetics by using pea plants. In one of his experiments, Mendel crossed yellow pea seeds with green pea seeds. Much to Mendel’s surprise, all of the offspring were yellow peas.
Which of the following statements explains Mendel’s results?
A.When the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color.
B.When the two peas were crossed, the offspring received genes from both parent plants; the phenotype for yellow peas was dominant over green pea color, which caused all the offspring to have yellow seed color.
C.When the two peas were crossed, the offspring only received the genes from the parent plant which had the genotype for yellow seed color.
B.When the two peas were crossed, the offspring only received genes from the parent plant with the phenotype for yellow seed color, which caused all the offspring to be yellow.
Answer:
It's A
Explanation: They both have gene for both of the color but the yellow pea seed gene or whatever is dominant.
The statement that best explains Mendel’s results is when the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color. The correct option is A.
What is Mendel's law?Gregor Mendel was a scientist and botanist, and he experiments on pea plants and discovered three laws that are very helpful in genetics.
Mendel's law of segregation, "during gamete formation, every gene segregates from each other so that each gamete conveys only one allele for each gene." The second law of inheritance is the law of segregation.
Mendel's 2nd law of inheritance is also known as the law of independent assortment of genes.
It states that each character behaves as a separate unit and is inherited independently of any other character.
Therefore, the correct option is A.

Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species (species A) grows faster than the other garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates
Answer:
This question lacks options, the options are:
A) Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.
B) Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A.
C) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions.
D) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The answer is D
Explanation:
According to this question, Ruby wants to investigate whether a plant species A in her garden grows faster than other plant species (B, C and D) due to the varying height she observed in them. To do this, Ruby will need to conduct a scientific investigation by measuring the height of all the plant species she is trying to compare (A, B, C, D).
However, she must do the measurements under the same conditions i.e. controlled in order not to influence the result. In order to make a scientific explanation concerning the plant growth rates, Ruby should find journal articles that describe the growth rates of each species and make comparison with her experimental/measured height values.

Predict the two possible outcomes if temperature or pH were changed within the molecular control system of cell division.
I'm pretty sure it's that the cells would divide more or divide less, right? Because the temp or pH change would cause some enzymes to denature, and then, depending on which ones denature, the regulation of cell division would be messed up and they would either divide too much or not enough?
Answer:
Yes, pH and temperature affects the cell division.
Explanation:
If the temperature falls between the range of 3 °C to 25 °C, the mitosis process increases but when the temperature lowers from 3 °C and exceeds from 25 °C so it decreases the rate of mitosis process because the enzymes which is responsible for the process of mitosis denatures and does not work properly. same is the case with pH, the rate of the process will increase when the pH is neutral but decreases when the pH goes lower or higher.
Fish give off ammonia, a base, as a waste. How does this
