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."

Two populations live in the same habitat and compete for food. The first group is larger and multiplies through asexual reproduction; the second reproduces sexually. What could happen to cause the second group to outnumber the first?
Answer:
an environmental change that causes the larger but unadaptable species to die off
Explanation:
Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.
What happen when the process of meiosis does not takes place?If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.
The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has formed which gives rise to the organism having diploid cells.
Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.
The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.
The reaction of photosynthesis is given below:
[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]

Energy Released from the cellular respiration of glucose is
A.First stores within ATP
B.Stored in the liver as fat
C.Turned into fat
D.used directly for body activity
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule. To this extent, the Answer is (A)
Explanation:
Brainliest Please
Energy that is released from the cellular respiration is called as the ATP that is adenosine triphosphate. It is the energy currency of the cell.
What is the number of phosphate in ATP ?The number of phosphates in the molecule of ATP is 3 phosphates.
Glucose and the other food's molecules get broken down by the controlled stepwise oxidation in order to just provide the chemical energy in form of ATP and the NADH. Energy that is released during breakdown of the glucose and the other organic fuel molecules that are from the carbohydrates with fats and the proteins in the glycolysis is just captured and then stored in the ATP.
During the cellular respiration the glucose is just broken down in presence of the oxygen in order to just produce the carbon dioxide with water. Energy that is just released during reaction is just captured by energy-carrying molecule that is ATP (adenosine triphosphate).

Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability

One result of climate change is that ocean temperatures are increasing. If the temperatures continue to rise, what effect will that have on the oceans’ ability to retain CO2? How might this change affect the atmosphere? THIS IS SCIENCE WOULDNT LET ME SELECT IT
Answer:
See explanation
Explanation:
There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.
Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.

Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

The possible allele combinations from the gametes of an organism with the genotype of AaBb is AB, Ab, aB, and ab. The correct option is D.
What are alleles?Alleles are variations of the gene. The offspring contain genes or traits from both parents. The same trait is given by both parents, one become dominant and one become recessive.
A gamete is a haploid cell that fuses with another cell to produce offspring, This occurs during fertilization. The female gamete is called ova or egg, or male cells are sperms.
When the genotype that will be produced by the fusion of AaBb is AB, Ab, aB, and ab. The small letters denote the recessive gene and the capital letter denotes the dominant genes.
Thus, the correct option is D. AB, Ab, aB, and ab.
