The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?

The addition of a new food source into the river that limits competition for
resources

Tourism that helps fund the educational programs related to river ecosystem
conservation

Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river

Increasing water consumption that decreases the flow of clean water from the
springs that feed the river

Answers

Answer 1

Answer: Increasing water consumption that decreases the flow of clean water from the

springs that feed the river

Explanation: Because the salamanders have less clean water, pollution becomes more of a problem, also all of the other options would help the salamanders.

Answer 2

The human activity that would most likely decrease the ability of the salamanders to survive is increasing water consumption, which decreases the flow of clean water from the springs that feed the river, which is the last option.

What are the human activities that lead to habitat loss?

The salamander is only found in a limited area of the San Marcos River, which relies on clean water from the springs, so decreasing the flow of clean water would negatively impact the salamander's survival, as it depends on specific water conditions for survival. As water is withdrawn from the springs to meet human needs, such as agriculture, industry, or household use, less water is available, which can have a detrimental effect on the habitat that the salamander requires because of human needs.

Hence, increasing water consumption decreases the flow of clean water from the springs that feed the river, so the last option is the correct option.

What is the role of light and chlorophyll in photosynthesis?

Answers

Explanation:

During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

In photosynthesis, role of light is to convert water and carbon dioxide to organic products and chlorophyll helps in absorbing light energy from the sun.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

How did Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach?

Answers

Absorption of the nutrients will not happen in her small intestine.

Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach because the intestine is responsible for the absorption of most of the nutrients produced from eating and drinking of food substances.

If the absorption of the nutrients will not happen by the intestine, the whole homeostasis or equilibrium of the body disturbs and no growth of the cell  occurs so we can conclude that absorption of the nutrients will not happen in her small intestine.
