1. An electron carrier transports electrons and their energy to another molecule.

2. The equation of photosynthesis is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

3. In the stroma NADPH and ATP combine with carbon dioxide to produce sugars.

4. In the thylakoid membrane, light energy from the sun splits water and generates ATP and NADPH.

5. Chloroplasts are not found in heterotrophic cells.

6. Autotrophs need light to carry out photosynthesis.

Why are the answers correct?

An electron carrier is an important molecule involved in cellular respiration as it transports electrons, along with their energy, to another molecule.

Photosynthesis is the process by which plants and organisms such as algae use energy from the sun to convert water, and carbon dioxide to produce oxygen and sugar.

The stroma uses ATP and NADPH in the next stage of photosynthesis to produce three-carbon sugars.

The thylakoid membrane contains chlorophyll and is located in the stroma where the light energy from the sun splits water and generates ATP and NADPH.

In summary, chloroplasts are organelles found in the cells of autotrophs and not heterotrophs.

Explanation:

Gray population rabbits would blend into either environment would most likely happen to the gray rabbits. So, the correct option is A.

A population is a collection of organisms belonging to the same species that co-exist in the same place and are able to reproduce. Members of a population interact with each other through mating, competition for resources, and other social behaviors. They also share a common gene pool.

The ratio of the birth rate of a population to its death rate as well as immigration and emigration determine the size of the population. When the birth rate exceeds the death rate, population growth results; When the death rate is high, the population declines. Emigration occurs when people leave a population to go elsewhere, whereas immigration occurs when people move into a population from outside.

So, the correct option is A.

Motor end plate  is the indented region of the sarcolemma that participates in the neuromuscular junction.

The extensive spectrum of illnesses that affect the peripheral nervous system, which is made up of all the motor and sensory nerves that connect the brain and spinal cord to the rest of the body, includes neuromuscular disorders. These illnesses are characterized mostly by progressive muscular weakening.

A gene mutation or an inherited condition can both result in neuromuscular disorders; immune system issues can also contribute to several of these conditions.

One of the most debilitating conditions that impact nerve system and muscle function is amyotrophic lateral sclerosis (ALS), which results in the gradual degradation of nerve cells in the spinal cord and brain. No senses are impacted with ALS (such as seeing or hearing). In most cases, it has little impact on mental capabilities. It's not spreadable. There isn't a treatment for this illness as of now.

Answer:

The correct answer is B. "Melanocytes and muscle cells express different genes."

Although all cells in an organism (such as a human) contain the same DNA, different cell types express different sets of genes. Gene expression is the process by which specific genes are activated to produce a needed protein. In this case, the gene responsible for melanin production is expressed in melanocytes, but not in muscle cells.

This does not mean that muscle cells have destroyed the gene for melanin (as stated in option C) or that melanocytes contain different genes from muscle cells (as stated in option D). All cells within an organism contain the same genes, but not all genes are expressed in every cell. The process of gene expression is regulated by the cell to ensure that each cell type functions properly.

Option A is also incorrect because all cells, including both muscle cells and melanocytes, rely on both DNA (for storing genetic information) and RNA (for transmitting that information and producing proteins). DNA is transcribed into RNA, which is then translated into proteins. This process occurs in all cells.

The statement explains the difference between skin melanocytes and muscle cells is - melanocytes and muscle cells express different genes. So option b  is correct.

Melanocytes are dark, dendritic-shaped, highly differentiated cells that secrete melanin, a pigment found in melanosomes, which is the primary function of melanocytes.

Melanocytes are a type of cell derived from the neural crest. They form a synapse with keratinocytes through their dendrites in the epidermis. Melanocytes play an important part in skin pigmentation and their role in the generation and distribution of melanin has been extensively studied.

Answer:

Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance. In this way, the concentration of hormones in blood is maintained within a narrow range.

Explanation:

The important way competitive inhibition differ from allosteric inhibition is competitive inhibition involves competition for the active site, while allosteric inhibition involves regulation by a molecule binding to a different site on the enzyme.

Competitive inhibition and allosteric inhibition are two types of enzyme inhibition that have important differences. Competitive inhibition occurs when a molecule that is similar in shape to the substrate competes with the substrate for the active site of the enzyme. This molecule, called the inhibitor, binds to the active site and prevents the substrate from binding, leading to a decrease in enzyme activity.

In contrast, allosteric inhibition occurs when a molecule binds to a site on the enzyme that is not the active site, causing a conformational change in the enzyme that reduces its activity. This type of inhibition is usually regulated by feedback mechanisms and can have a more significant impact on enzyme activity than competitive inhibition. In summary, competitive inhibition involves competition for the active site, while allosteric inhibition involves regulation by a molecule binding to a different site on the enzyme.

Answer:

Claim:

The increase in the population of the Burmese python in Everglades is affecting the ecosystem of said area. They are an invasive species.

Evidence:

From 1994 to 2007, the Burmese python population increased from a small number below 50 species to more than 250 by 2007. As the Burmese population increased, the mammals' population in Everglades decreased significantly and even had extincted some species. For example, from 1993 to 1999, there were 64 white-tailed deer and five red foxes, and grey foxes. Between 2003 and 2011, there were 24 white-tailed deers and 0 foxes. Overall, there is a decrease in all mammals.

Reasoning:

The increasing number of Burmese Pythons due to the release of them by pet owners and due to the destructions of a private reptile breeding facility left a high number of pythons in the wild. As a consequence, these pythons ate other animals producing an imbalance in the Everglades ecosystem. Owing to its large number and how they are harming the ecosystem, they are considered an invasive species.

Explanation:

After analyzing the information, the claim is that the increasing population of pythons harms the Everglades' ecosystem.

The evidence that supports the claim is present in the graphics, where we can see how the population of this reptile grew over the years, and the mammals' population decreased. There is specific information about the reduction in the number of mammals in the area, such as the raccoon, foxes, rabbits, etc.

After presenting the evidence, the reasoning that we can make is that the pythons are killing the other animals in Everglades. Also, we can see that they are not a native species from the area since they were released by pet owners and by a breeding facility by accident. The fact that they are harming the Everglades' ecosystem and that they are not native species makes them an invasive species.
