A testable hypothesis is one that can be tested through empirical research, meaning that it is possible to gather evidence to support or refute it.

A hypothesis is a possible explanation that is proposed for a phenomenon that occurs in nature. In the scientific method, hypotheses are tested by collecting and analyzing data to either support or reject them.

A testable hypothesis could be formed from a question by using the following steps:

Identify the phenomenon that you want to study: Start by identifying the phenomenon that you want to study. This could be a relationship between two variables or a question about how something works. Develop a research question: Based on the phenomenon you want to study, develop a research question that can be answered through empirical research. This question should be specific and should be able to be tested using scientific methods. Formulate a hypothesis: Using your research question, formulate a hypothesis that can be tested through empirical research. This hypothesis should be a statement that proposes a possible explanation for the phenomenon you are studying. It should be clear, concise, and testable.

Test the hypothesis: Once you have developed a testable hypothesis, you can design and conduct experiments to gather data that will either support or refute the hypothesis. If the hypothesis is supported by the data, you can consider it to be a valid explanation for the phenomenon you are studying. If the data refute the hypothesis, you may need to revise it or develop a new hypothesis.

The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.

Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:

Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.

Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.

Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.

Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.

Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.

By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.

The trend that is evident is: Initially, there seems to be support for Mel's hypothesis, but the gold data is not consistent with the predicted trend.

Option C is correct.

The data for zinc, nickel, copper, and silver shows that as the density increases, the melting point tends to increase.

From the data we can see , the data for gold does not follow this trend, as its density is lower than silver but its melting point is higher.

Therefore, while there is some initial support for Mel's hypothesis, the inconsistency with gold indicates  that the relationship between density and melting point is not solely determined by density.

Blood vessels act as transporters for the distribution of nutrients and oxygen to the various parts of the body.

In the lungs, oxygen is bound to hemoglobin present in RBCs which through the blood flow reaches every tissue of the body. The RBCs present in the larger blood vessels move to the smaller blood vessels and then to reach the tissues enter the capillaries, from where the gas exchange occurs. That is oxygen is given to the tissue and carbon dioxide is collected from the tissue.

 The sum of the mass of product  and reactants must always be the same.  

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Answer:

Inhibitory proteins

Explanation:

Allosteric site = a binding site on the protein other than the active site

Allosteric effector molecules don't resemble the structure of the substrate. So, they cannot bind to the active site. Instead, they bind to an allosteric site and alter the conformation of the protein such that the activity of the protein is affected.

Allosteric effectors can be activators or inhibitors, i.e. the conformational change in the structure can activate or repress the protein function.

Allosteric proteins can also be regulatory proteins (Activators or inhibitors) or enzymes.
