Though we now see large cities across Southern and Eastern Asia as living with unbearable pollution, we forget that we experienced similar levels of pollution in the United States. In LA in WWII, the brown-colored smog grew so dense, people thought that Japanese had attacked them with chemicals. Many people who grew up there reported that it "hurt to breathe" and would get teary eyes on bad days. It was hard to get air pollution legislation in California and the U. S. Because the car industry didn’t want to be blamed and people were scared that new catalytic converters that removed [pollutant] from emissions would make cars too expensive. (Plus people didn’t understand the connection because auto emissions were clear and the smog was brown. ) Haagen-Smit, a biologist studying the flavor of pineapples, found the connection. But, the oil and automobile industries funded the Stanford Research Institute to discredit Haagen-Smit. At one point, someone offered to disprove Haagen-Smit’s findings by voluntarily sitting in his plexiglass smog chamber. This person got bronchitis. Haagen-Smit continued his research so that by the 1950’s the connection was clear. Activists groups sprang up and clamored for pollution control legislation. From this and other pollution crises, the Clean Air Act was born
Clean Air Act is necessary for the reduction of pollution in cities.
What is Clean Air Act?The Clean Air Act provides necessary tools to the Environmental Protection Agency which takes initiatives in order to protect our families from harmful pollutants that can cause various disease so we can conclude that Clean Air Act is necessary for the reduction of pollution in cities.

The letter A indicates _____. lateral meristem secondary xylem apical meristem vascular cambium cork cambium
The secondary xylem is produced by the cambium. It is placed between the cambium and the medulla. Option B is correct. Secondary xylem.
What is the secondary xylem?The secondary xylem is the tissue that proceeds from the vascular cambium activity.
Its cells are orientated in different ways composing the vertical/axial system and the horizontal/transversal system.
The secondary xylem is essential to the tree growth in high because of its resistance and the capacity to transport water long distances.
Secondary xylem functions are to transport water and minerals through its vessels and tracheids, to provide support and resistance to the plant, and to store reserve substances.
In the cross-section of the adult tree trunk,
The outermost layer that interacts with the environment is called periderm (Brown Layer). The second layer that follows the periderm is the phloem (Layer C). The next layer is the cambium (lateral meristem), which produces phloem cells and xylem cells (Layer B). The secondary xylem follows the vascular cambium (Layer A), and The medulla is located in the centre of the trunk.Letter A indicates the secondary xylem.

The letter A in this context refers to the apical meristem, which plays a crucial role in plant growth and development.
Apical meristem is a type of meristem found at the tips of stems and roots. Meristems are regions of actively dividing cells that are responsible for growth in plants.
The apical meristem is responsible for primary growth, which is the growth in length of the plant. It allows the plant to increase its height and lengthen its roots. The cells in the apical meristem divide rapidly, producing new cells that differentiate into various types of tissues.
This type of meristem is important for the development of the plant body. It produces the cells that make up the primary tissues, including the epidermis, cortex, and vascular tissue. The apical meristem also gives rise to lateral meristems, which are responsible for secondary growth in woody plants.

A bird species requires abundant shoreline and a high population of insects within its habitat. You observe a population of these birds with a low density and adequate resources, but the population seems to be growing very slowly. What might be an explanation for the slow population growth?
Answer:
i am not sure of this answer because there are a lot of answers for this question but what i came up to is that there might be a large population of different predators that hunts down this bird species
Explanation that means that the more the predator feeds on this bird species ( and other species too , unless this species is the predator's main source of food) the more the population of predators increase and that means that the predators will keep feeding on this bird species until it completely wipes out this bird species or the bird species migrates to an area where there are less predators.
