Describe the role of enzyme in metabolism

If the enzyme salivary amylase were present at 70℃, it will be denatured and won't be able to act on its substrate which will lead to low sugar inside the bloodstream and the person may experience nausea and death in serious cases.

This is referred to as a biological catalyst which is responsible for speeding up the rate of chemical reaction in the body and examples include amylase etc.

Amylase is an enzyme which digests starch and converts it into sugar which provides the required energy for the body system. In a scenario where amylase is absent the individual may become very weak and get diarrhea from undigested carbohydrates.

Creating a butterfly garden can have several important benefits, particularly in the context of declining butterfly populations and the impact on biodiversity.

1. Declining Butterfly Numbers: Over the years, butterfly populations have been declining due to various factors. Habitat loss and fragmentation, pesticide use, climate change, and pollution are some of the significant contributors to this decline. These factors have resulted in the loss of host plants for butterflies and a reduction in suitable habitats for their survival and reproduction.

2. Impact on Biodiversity: Butterflies play a crucial role in ecosystems as pollinators. They visit flowers for nectar, thereby facilitating the transfer of pollen and contributing to plant reproduction. Many plant species rely on butterflies and other pollinators for their pollination, which is essential for the production of fruits, seeds, and overall plant diversity. Declining butterfly populations can disrupt this pollination process and have cascading effects on other organisms that depend on these plants.

3. Biodiversity: Biodiversity refers to the variety of life forms, including plants, animals, microorganisms, and their interactions within an ecosystem. It encompasses the genetic, species, and ecosystem diversity present in a particular area. Biodiversity is crucial for the stability, resilience, and functioning of ecosystems, providing essential ecosystem services such as pollination, nutrient cycling, and pest control.

4. Significance of Biodiversity Loss: The loss of biodiversity, including declining butterfly populations, is significant for several reasons. Firstly, it can disrupt ecological balance and lead to the loss of critical ecosystem functions. For example, the decline of butterfly pollinators can reduce the reproduction and diversity of plant species, affecting food webs and the availability of resources for other organisms. Secondly, biodiversity loss can reduce the overall resilience of ecosystems, making them more vulnerable to environmental changes and less able to recover from disturbances. Finally, biodiversity loss can have economic and cultural impacts as well since it affects agricultural productivity, tourism, and human well-being linked to natural environments.

By creating butterfly gardens, we can provide suitable habitats and food sources for butterflies, promoting their population recovery and enhancing biodiversity. These gardens can serve as important stepping stones and corridors for butterflies to move between fragmented habitats. Additionally, butterfly gardens offer an opportunity for education, appreciation of nature, and conservation awareness, helping to inspire individuals to take action in preserving biodiversity.

Explanation:

The three human activities that have a negative impact on the biodiversity within Amazon rainforests are captive breeding of organisms, introduction of invasive species and restoration of degraded land.

The unique biodiversity of the Amazon rain forest has been threatened by deforestation caused by clear-cutting forests for hardwood timber, and to provide pastureland for cattle and crop farms.

Biodiversity loss from habitat destruction is often driven by land grabbing and industrialized agricultural expansion, mining, logging, and large-scale infrastructure development, usually through deforestation.

harles Darwin is renowned in many countries across the globe as the man who developed the Theory of Evolution. His theory sets about explaining the progressive changes that occur within species down the generations, as well as the formation of new species, when environmental pressures have differential effects on the reproductive success of all individuals.

Darwin's first observation illustrates this as evolution describes changes in inherited traits of populations through successive generations. To fully understand the science of ecology, one must first be able to grasp evolutionary concepts. Members of a population often vary in their inherited traits.

The three types of waste removal are:

1. Urea

2. Metabolic gases

3. Non-digested food

Urea is the waste formed in our body as a result of protein break down which is excreted as a major component of urine

Metabolic wastes like CO2 are formed as a result of cell restoration that is released through the lung's expiration.

Non-digested food in the intestine is removed from the body as faeces

Answer:

Urine, sweat, and carbon dioxide

Explanation:

A type of waste is urine because uric acid is removed from the kidneys in the form of urine. Another waste product is when excess water is removed from the skin in the form of sweat. The 3rd waste that is removed is carbon dioxide which is removed from the lungs be exhaling. Waste removal is important to living things because it controls homeostasis and it removes toxic waste, and removes things that are no longer needed in the organism.

The abiotic water pH factor in coastal aquatic habitats is what most inhibits a fishery's productivity.

The majority of aquatic species do not have to contend with extremes in wetness or temperature. Instead, the amount of sunlight available to them and the water's concentration of dissolved oxygen and nutrients are their primary limiting variables.

Ecosystem-specific differences in net primary production exist. They include the amount of solar energy intake, the temperature and humidity, the amount of carbon dioxide, the availability of nutrients, and community interactions.

Characteristics found in germ lines are generally passed down to the next generation of offspring through sexual reproduction, whereas traits found in somatic cells are not.

Traits, also known as characteristics, are generally passed on to the next generation as they are present on germ line cells, such that in the case of the male, they produce sperm so, the active genes on the sperm will express in the offspring, and in the case of the female, the active gene on the ovum will express in child.

Hence, characteristics found in germ lines are generally passed down to the next generation of offspring through sexual reproduction, whereas traits found in somatic cells are not.

Answer:

Accumulation of lactic acid

The anaerobic cellular process is a type of respiration that occurs in the scarcity of oxygen. Lactic acid gets accumulated in anaerobic respiration during vigorous exercise. Thus, option A is correct.

Anaerobic respiration is a cellular process where the organic and the biological fuel are broken and oxidized through the electron transport chain in the cytoplasm of the cell.

The anaerobic cellular process lacks the use of oxygen so to produce energy like ATP and lactic acid accumulation due to the high energy demand during vigorous exercise.

In the anaerobic cellular process, carbon dioxide and water are formed as a byproduct along with lactic acid and ATP. Lactic acid is formed from the breakdown of glucose and glycogen.

Therefore, in option A. in the anaerobic cellular process, accumulation of lactic acid occurs.

Concept Map: 1. Electrical Stimulation: The electrical stimulation generated by the sinoatrial node (SA node) or an artificial pacemaker causes ion channels in the cardiac pacemaker cell to open, allowing for the flow of ions into and out of the cell.

Electrical stimulation (ES) is a form of treatment that utilizes a low-level electrical current to stimulate nerve endings in order to decrease pain, increase muscle strength and improve circulation. Electrical stimulation works by delivering a low-level electrical current to the target area of the body.  

2. Action Potential: The action potential is generated when positively charged ions, such as sodium and calcium, enter the cell and cause the membrane potential to become depolarised.

3. Repolarisation: Potassium ions then leave the cell and cause the membrane potential to become repolarised.

4. Conduction Pathway: The action potential then travels along the conduction pathway, which includes the atrioventricular node (AV node), bundle of His, and Purkinje fibers.

5. Contraction: When the action potential reaches the contractile cells, calcium ions enter the cells, causing the cells to contract.
