Which of the following statements are true? Check all that apply. Atoms of the same element can have different numbers of protons. Atoms of the same element have similar chemical behavior. Atoms of the same element can have different numbers of electrons. Atoms of the same element can have different numbers of neutrons.
Answer: Atoms of the same element have similar chemical behavior
Atoms of the same element can have different numbers of neutrons.
Explanation:
Atoms of the same element have similar chemical behavior as it is decided by the number of electrons which remains same for same elements.
Mass number is defined as the sum of number of protons and neutrons that are present in an atom. Atomic number is defined as the number of protons or number of electrons that are present in an atom.
Isotopes are elements which have same atomic number but different mass number. That means they are same elements with same number of protons and electrons but different number of neutrons. Example: [tex]_1^1\textrm{H}[/tex] and [tex]_1^2\textrm{H}[/tex]

Which of the following is an extensive property? Boiling point Magnetism Melting point Volume
Answer:
Volume
Explanation:
The physical properties of matter are either classified as extensive or intensive. Extensive property of matter is a property that is dependent on the amount of matter contained in the substance. On the other hand, intensive properties are rather dependent on the type of substance and not the amount or size.
Based on this explanation, VOLUME is an extensive property because its measure is dependent on the amount of matter in the measured substance. Hence, a difference in the volume of two substances is as a result of the amount of matter contained in each of them.
On the other hand, boiling point, melting point and magnetism are all properties that depends on the type of matter.

What type of growth would you expect to see in a population that has migrated to a new habitat?
Answer:
Exponential growth
Explanation:
Exponential growth is a type of growth that increase in quantity over time.
When a population migrate to a new habitat it shows exponential growth because in the beginning, the growth rate is slow as population adapts the new environment and once they evolve according to the environment, they will grow exponentially.

. Which of the following is a chemical reaction? A. breaking a glass pane B. freezing water C. digestion of food D. cutting down a tree E. evaporation of rubbing alcohol
Answer:
C. When we digest food there are tons of chemical reactions occurring in the process, they would have to break down the food which is a chemical reaction.
Answer:
C. digestion of food
Explanation:
in a chemical reaction the substance changes composition and the reaction is mostly irreversible.
option C: digestion of food is a chemical reaction which changes the composition of the food we eat. Enzymes and other substances react with the food and turn it into soluble substances which the body can easily use.
option A: breaking glass does not change the composition of the glass plane. Its a physical reaction
option B: freezing water changes the state of water but the composition is still the same, its a physical reaction as well.
option D: cutting a tree does not change the composition of the wood. This, too, is a physical reaction.
option E: when a liquid evaporates it changes into a gas, which is a change in the state of matter (just like water into ice), this also does not change the composition of alcohol.
In a jungle habitat, there lives a species of snake, called Species A. The carrying capacity of the jungle allows 5000 of Species A. After their habitat was destroyed, a second species of snakes, Species B, arrives in the jungle. After a few years, the population of Species A has dropped to 0, and the population of Species B has become 5000. What can you determine from this data?
Answer:
See the answer below
Explanation:
From the data, it can be concluded that the habitat's carrying capacity for snakes is 5000 and this was not influenced by the alteration/destruction that happened to the habitat.
It can also be concluded that species B snake is a better fit - than species A snake - for the new environment resulting from the destruction of the initial environment.
The fitness of species B can be attributed to either their natural fitness to the new environment due to evolution or their ability to outcompete species A in the environment. The reduction in fitness of species A leads to their gradual fading off of the new environment while the fitness of species B leads to them reproducing and contributing more to the population of snakes in the environment.

Which serves as evidence for a scientific claim?
surveys of public opinion
company advertisements
controlled experiments
personal websites
The correct answer is C. Controlled experiments
Explanation:
A scientific claim is a statement that describes or explains a phenomenon of the world. These statements can be proven as valid or invalid only through scientific experiments, which involve testing in controlled conditions the phenomenon. This is the only way because the scientific method should be followed. For example, if the claim is that humidity affects the growth rate of cacti. The researcher will need to use multiple cacti and use different percentages of humidity to prove if humidity increases or decreases the growth rate. Also, in this case, other factors such as nutrients in the soil, exposition to sunlight, etc. should be controlled to guarantee these factors are equal for all plants. According to this, the one that serves as evidence for the scientific claim is controlled experiments.

Explanation:
Eye color is and example of
a. Translation control
b. Gene expression
c. Transcriptional control
d. Gene regulation
Answer:
b. Gene expression
Explanation:
The eye color trait is controlled by polygenetic heritability. A group of genes is responsible for the trait manifestation, and they must be associated to transmit the characteristic.
Eye color in a person is produced by pigments in the iris´ cells called melanocytes. At least two or more genes control melanin synthesis in the iris. Melanosomes are cellular structures produced by melanocytes, where melanin is produced and stored. Different genes control the eye color by its expression. We can name two of them as examples. There is a gene called OCA2 that codifies for the P protein synthesis. This protein plays an important role in the amount of melanin produced. The less P protein, the less melanin the cell will produce, which leads to blue eyes. Another gene called HERC2 contains a region known as intron 86 that controls the OCA2 gene, by allowing or inhibiting its expression.

Do any cells in the population express Glut4 on their surface? Is this expression dependent on the presence of insulin receptor? Is this expression dependent on the presence of insulin? Explain.
Answer:
Glut4 is only expressed in insulin-sensitive skeletal an heart muscles and fat tissues.
Explanation:
Glucose transporters represent a group of integral membrane proteins that allow the transport of glucose molecules across the plasma membrane by the mechanism of facilitated diffusion (i.e., without direct coupling to ATP hydrolysis). In humans, the Glucose Transporter type 4 (GLUT-4) is a glucose transporter encoded by the SLC2A4 gene. This protein plays a critical role in regulating glucose homeostasis by enabling to increase the transport of glucose in response to elevated blood insulin levels in adipocytes, skeletal and cardiac muscle tissues.
how do scientists decide when to change or modify their understanding of a particular topic?
Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).

Which of the choices below determines the direction of respiratory gas movement?
a. pulmonary ventilation
b. transport of respiratory gases
c. external respiration
d. pulmonary respiration
Answer:
a. pulmonary ventilation
Explanation:
Pulmonary ventilation: In biology, the term "pulmonary ventilation" is also referred as "breathing" and is described as a phenomenon of moving air out and into an individual's lungs. Generally, air enters the "respiratory system" via nasal cavity and mouth, and then it passes through the "pharynx" and then the "larynx" and lastly to the "trachea" that enters the "chest cavity" of an individual.
In the question above, the correct answer is option A.
In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Progeny of: Plant A Plant BDd Pp 122 2 Dd pp 6 82 dd Pp 4 82 dd pp 124 4 a.What are the genotypes of plant A and B
Answer:
The correct answer would be - Dd Pp.
Explanation:
As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP . similarly the recessive trait that is dwarf and pubescent plant would be ddpp
Thus, the cross between these would be -
DD PP x ddpp
And gametes would be - DP,DP, dp, and dp.
So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype .
Thus, the correct answer would be - Dd Pp.

a. Add to the formula in Interactive Question 3.5 to
show how increasing (CO2) dissolving in water leads
to a lower pH.
b. Use this formula to explain how a lower pH would
affect the [CO32-) in the ocean.
HCO3 SCO32- + H+
c. Assuming a fairly constant (Ca2+] in the ocean, how
would a change in (CO32-) affect the calcification
rate--the production of calcium carbonate
(CaCO3)-by the coral in a reef ecosystem?
Answers and Explanation:
a.)
Lower pH of a substance is indicative of increased acidity. By dissolving carbon dioxide to release [tex]CO_{3} ^{2-}[/tex] which easily reacts with water to form carbonic acid, thereby increasing water acidity.
b.)
The increased acidity of the ocean makes the water naturally corrosive and soft which implies reduced carbonate levels in the ocean.
c.)
Calcification occurs through formation of calcium carbonate by reaction of calcium with carbon dioxide, or even more easily Ca2+ and [tex]CO_{3} ^{2-}[/tex]. This implies that increased calcium levels in the ocean increases rate of calcification and reduced [tex]CO_{3} ^{2-}[/tex] ions.
