why is endosymbiotic theory not a law in science?
Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.
Explanation:
What happens when a cell gets too large?
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

D Vestigial organs show how many cells organisms of a species once had.
Answer:
Vestigial organs show traits that a species once needed to have to perform certain tasks
Explanation:
B. Vestigial organs provide evidence for the theory of evolution:
"Vestigial organs show traits that a species once needed to have to perform certain tasks."
What do you mean by vestigial organs?
"Vestigial organs are the organs that have no apparent function and are considered to be the residual parts from the past ancestors."
What is theory of evolution?
"Theory of evolution is a scientific theory of the origin of species of plants and animals."
What do you mean by species?
"A species is often defined as a group of organisms that can reproduce naturally with one another and create fertile offspring."
What is a trait?
"A trait, as related to genetics, is a specific characteristic of an individual."
How are vestigial organs related to theory of evolution?
"Vestigial organs are often homologous to organs that are functioning normally in other species. Therefore, vestigial organs can be considered evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time."

Summarize taste considerations.
The word taste, or gustation, to give its full name, refers to what is detected by the taste cells, located on the front and back of the tongue and on the sides, back and roof of the mouth. These receptor cells, or taste buds, bind with molecules from the food or drink being consumed and send signals to the brain.
How is a spark from touching a doorknob the same as a bolt of lightning
Explanation:
That little spark you get when you touch the doorknob is essentially a miniature lightning bolt. When rain clouds move through the air, they build up positive and negative electric charges (Figure 7). So clouds have static electricity too! And when enough charge builds up, electric charges jump between the cloud and the ground.

How could plants living in an industrial area be affected by smog?
Answer: The ground level ozone present in the smog also inhibits plant growth and causes immense damage to crops and forests. ... The smog results in mortifying impacts on the environment by killing innumerable animal species and green life as these take time to adapt to breathing and surviving in such toxic environments.
Explanation:
A type of air pollution in which the fog and smoke get mixed in the atmospheric air is called smog. It causes opacity and odour in the environment.
Smog is released from the factory that contains carbon dioxide, sulfur dioxide and smoke from the outlets.
Smog blocks the sunlight and the chemical released goes into the root system of plants interfering with the plant metabolic processes.
This causes damages to the leaves of plants and inhibits the plant process.
Therefore, smog from industries kills the plant.

Explain the effects of air pollution on several European countries. (Site 1)
Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?
Answer:
Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.
Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.
