Science Concepts
How do the science concepts connect to the evidence and reasoning to help answer the question? Identify the concept first, then describe/explain how it relates to your evidence and reasoning.
Concept: Cause and Effect - Events generally have a cause or action that triggers a response. Many times, you will observe the effect first, and then think about what may have caused this to happen.
Identify a Cause and Effect Relationship within the topic of Evolution.
One example of a cause and effect relationship within the topic of evolution is natural selection. The cause of natural selection is the variation that exists within a population.
The effect of natural selection is that the individuals with traits that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This results in changes in the frequency of traits within a population over time, ultimately leading to the evolution of new species.
Evidence for this cause and effect relationship can be seen in the fossil record, as well as in observations of organisms in modern-day environments. By observing the traits that are present in different populations and the environments in which they live, scientists can use reasoning to explain how natural selection has led to the evolution of different species.

1) if big molecules can't get absorbed in the small intestine, why aren't there other big molecules besides fiber, like complex carbohydrates, coming out in the poop of healthy people?
2) what's happening to the other big molecules like complex carbohydrates? how can we explain why the amount of complex carbohydrates could be decreasing as food travels through the digestive system?
yall plss help me pls ill give brainlist just pls help me
a.b. Complex carbohydrates can be broken down into smaller molecules during digestion, but they are not broken down to the extent that fiber is. Fiber is composed of indigestible plant material and is not broken down by enzymes in the stomach or small intestine.
Instead, it passes through the digestive system largely unchanged, providing bulk and helping to regulate bowel movements. The other big molecules in food, such as complex carbohydrates, are broken down into smaller molecules during digestion and absorbed into the bloodstream for use as energy or for the production of other substances.
However, some of these molecules may not be absorbed as efficiently as others, and some may be excreted in the feces. Factors such as the type and amount of food consumed, the presence of digestive disorders, and the efficiency of the digestive system can all influence the amount of complex carbohydrates that are absorbed and excreted.

Would samples that were digested with ecori have a different pattern than the same sample digested with smal?
Yes, samples that were digested with EcoRI would have a different pattern than the same sample digested with SmaI.
This is because each enzyme cuts at different sites. EcoRI binds to a specific sequence of 6 base pairs, 5’-GAATTC-3’, and cuts between the G and A, creating two DNA fragments with a 3’-overhang. In comparison, SmaI binds to the sequence 5’-CCCGGG-3’ and cuts between the C and G, creating two DNA fragments with a 5’-overhang.
Thus, the digestion patterns of the same sample with EcoRI and SmaI will be different. The differences in the digestion patterns can be observed through gel electrophoresis, where fragments of different sizes are separated in the gel and visualized with a UV transilluminator.
The fragments generated by EcoRI and SmaI will appear in different positions on the gel, allowing the differences between the two digestion patterns to be easily observed.

Plant hormones server as a chemical messenger between cells and tissues. Auxin is a plant hormone that causes the cell on the shady side of a plant shoot to elongate. The response enabled by auxins is known as
Answer:
The response enabled by auxins, specifically the elongation of cells on the shady side of a plant shoot, is known as phototropism.
Explanation:
Phototropism is a plant's response to light, in which the plant grows towards the source of light. Auxins are produced in the apical meristem of the plant, and they are transported downwards through the stem towards the roots. When light shines on a plant, auxins accumulate on the shaded side, causing the cells on that side to elongate more than the cells on the sunny side. This results in the plant bending towards the light source, allowing it to maximize its exposure to light for photosynthesis. Auxins also have other functions in plant growth and development, such as promoting root growth and differentiation and inhibiting lateral bud growth.
The field of evo-devo proposes that many major morphological changes result from changes in gene __________ of regulatory genes. the premise for this argument is that these changes _______.
The field of evo-devo proposes that many major morphological changes result from changes in gene expression of regulatory genes.
The premise for this argument is that these changes cause modifications in the expression of downstream target genes, which then lead to alterations in structure and patterning.
Regulatory genes are those that control other genes, and changes in their expression can drastically alter the way in which an organism develops. Such changes can happen through mutations, whereby the regulatory gene acquires a new sequence, or through alterations in the timing and location of the gene’s expression.
For example, a mutation in a regulatory gene could cause the gene to be expressed at a different stage of development, leading to changes in the patterning of the organism’s morphology.
Alternatively, mutations in regulatory genes could cause the gene to be expressed in a different tissue, resulting in modifications of tissue structure. Through these changes in gene expression, major morphological changes can occur, allowing new species to emerge over evolutionary time.

Why are G-protein-coupled receptors referred to as metabotropic receptors?
Answer: because they can trigger widespread metabolic effects. Can someone explain how this is the answer?
G-protein-coupled receptors (GPCRs) are referred to as metabotropic receptors because they activate intracellular signaling pathways that can lead to widespread metabolic effects.
Unlike ionotropic receptors, which directly open ion channels upon binding to a ligand, GPCRs work indirectly by activating G-proteins, which in turn modulate intracellular enzymes and ion channels.
This signaling cascade can trigger a variety of metabolic effects, including changes in gene expression, enzyme activity, and ion flux, all of which contribute to the cell's overall metabolic state.
The term "metabotropic" comes from the fact that these receptors are involved in regulating metabolism, which refers to the chemical reactions that occur within cells to maintain life.
Metabolism is a complex process that involves the breakdown of nutrients, the synthesis of new molecules, and the production of energy.
GPCRs play a key role in modulating many of these metabolic processes by regulating the release of hormones, neurotransmitters, and other signaling molecules.
By activating G-proteins, these receptors can trigger a wide range of metabolic effects, making them an important target for drug development in many disease states.
