If you were to look at the age structure of a population of an endangered species and determine that there are mostly older individuals you could say that the population is declining and could be in danger of extinction.
<h3>What are
endangered species?</h3>
An organism that faces extinction is referred to as an endangered species. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Because it prevents our native fish, plants, and other animals from going extinct, the Endangered Species Act is crucial. There is no turning back once they are gone they are lost forever.
Endangered species are those that are at risk of going extinct and must therefore be safeguarded and conserved. Extinct species are those that no longer exist on the planet.
It's Important to Save Endangered Species because:
- From antibiotics to anti-cancer medications, they are the sources of those substances.
- They are the earliest indication of significant environmental problems.
- They support the well-being of crops (and, indirectly, people).
- They help the economy grow.

The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.
Answer:
E
Explanation:
Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others
the principle is defined by the equation
p² + 2pq + q² = 1
where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq
substitute the value into the expression
p² + 0.04 + q² = 1; The information is not enough to calculate either p or q going by the equation generated.

Decrease the amount of light using the iris diaphragm lever.
Plants do not grow near the old copper mine because of the excess copper deposited in them impairs cellular processes and inhibits plant growth.
What are micronutrients?
These are required by plants in much smaller quantities less than 1% of the dry weight but are necessary for growth and development. There are 7 essential plant nutrients like boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and, chlorine (Cl).
Copper activates some enzymes in plants that are involved in lignin synthesis and are required in the process of photosynthesis.
Excess copper causes reduced seed germination, low shoot vigour, and lower iron availability. A deficiency of copper can lead to increased to susceptibility to diseases like ergot, which can cause significant loss in the yield.
Plants growing in the old copper mine have the excess deposition of copper in one place which affects the germination of seeds hence it is found difficult to grow in the old copper mine.
Plants can grow easily in a place that is further away from the old copper mine. Because there is a high concentration of copper dissolved in water in the soil, this helps the plant to grow by exhibiting the photosynthesis process.
