3.a
Explanation:
The graph labeling aggregate emissions (option a) shows that pollution control methods are having a positive effect in the United States. The proof is trending downward (option a) in this graph, with the percentage drop over this period reaching -63 percent, which is option A.
What is pollution control?Pollution control refers to the measures taken to reduce or prevent the release of pollutants into the environment or to mitigate their effects once they have been released. Pollution control measures can take many forms, including technological solutions, regulatory approaches, and behavioral changes. Examples of pollution control measures include the use of air and water filters to remove pollutants, the implementation of emissions standards for factories and vehicles, the promotion of recycling and waste reduction, and the development of alternative energy sources to reduce reliance on fossil fuels.
Hence, labeling aggregate emissions on the graph (option a) shows that pollution control methods are having a positive effect in the United States. The proof is trending downward (option a) in this graph, with the percentage drop over this period reaching -63 percent, which is option A.

Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.

If a population grows by 3 percent each year, the growth of the population is
A. exponential
B. linear
c. cubic
D. logarithmic
Answers
Answer:
A. (exponential) population
If a population grows by 3 percent each year, the growth of the population is exponential. Hence, option A is correct.
What is exponential growth?A function called exponential growth depicts an expansion within a population that happens at the same pace across time. If a population doubles or triples in size, you can assume that the data grows exponentially. Exponential decay is the inverse of exponential growth, in which data contracts rather than expands.
Bacteria are one of the best illustrations of exponential growth. Prokaryotic fission is a method of bacterial reproduction that takes around an hour. The population size of 100 bacteria would increase exponentially if we measured it every hour in a certain environment.
The population growth is exponential. Hence, option A is correct.

Which habitat is near the equator?
A. Tropical rain forest
B. Tundra
C. Deciduous forest
D. Desert
Answers
Explanation:
Tropical rainforest, also spelled tropical rain forest, luxuriant forest found in wet tropical uplands and lowlands around the Equator.
Tropical rain forest habitat is near the equator. So, the correct option is A.
Where is Tropical rain forest?The majority of tropical rainforests are found in the tropics, between latitudes 23.5°N (Tropic of Cancer) and 23.5°S (Tropic of Capricorn). Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia are all home to tropical rainforests.
With an average annual temperature of above 22 degrees Centigrade and yearly rainfall of over 200 cm, tropical rain forests can be found there. Because of their density, the earth is not illuminated by the sun. These forests contain a wide variety of tree species, each of which sheds its leaves at a different time of the year.
Therefore, the correct option is A.

Usable chemical energy on Earth begins as light energy, usually solar energy. Plants and other autotrophs convert solar energy to
Chemical energy via the process of photosynthesis. Carbon dioxide and water, in the presence of light, are transformed into glucose.
The chemical energy is stored in the chemical bonds of glucose and is released during the process of cellular respiration. Cellular
respiration releases the chemical energy stored in food molecules to produce high-energy ATP molecules. Macromolecules such as
carbohydrates and fats can be used as fuels for the production of ATP. All foods contain chemical energy, but the amount of chemical
energy is dependent of the type of food. The larger the compound, the more chemical bonds present and the greater amount of
available chemical energy. We can rank molecule size, from smallest to largest, as sugar, starch, fat. We refer to the stored chemical
energy in foods as calories. A calorie is the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius.
When we refer to the calories in food, we are really talking about kilocalories or 1000 calories. Biology students "burned" 2 grams of
food to heat water in a calorimeter in order to determine which food items contain the most usable chemical energy.
Almonds may be small, but they pack a great number of nutrients, including protein, vitamin E, and vitamin B2. Almonds also contain

an organisms haploid number if its diploid number is 32?
Answers
Answer:
The haploid (n) number would be 23 chromosomes found in the gametes, reproductive cells of sperm and ova. For the organism in this example the diploid (2n) number is 12 making the haploid (n) number would be half of that or 6 chromosomes
Answer:

Explanation:
This is because the diploid number of an organism is double the haploid number, therefore 32/2=16

The law of segregation explains that * alleles of a gene separate from each other during meiosis. different alleles of a gene can never be found in the same organism. each gene of an organism ends up in the same gamete. all of the above
Answers
Answer:
alleles of a gene separate from each other during meiosis.
Explanation:
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only rounded seeds appeared), while the other variant (wrinkle) disappeared. Mendel named "dominant" the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (R and r) and that the pair separates (segregates) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).
Horticulture 20 points!!!!!A landscape Blank provides organization and labor to install the plants and hardscape elements of a landscape, and may also provide the original design.
Answers
Answer:
Explanation:
En su texto, “General Elements and Principles of Landscape Design”, de Melvin Wong, miembro del Departamento de plantas tropicales y ciencias del suelo de la Universidad de Hawai en Manoa, dice que el diseño de paisaje “difiere de otras formas de arte tridimensionales” porque se basa, principalmente, en el uso de formas vivas de color verde que cambian a lo largo del tiempo según su “adaptación, estado nutricional y problemas de plagas”. (1)
Sin embargo, la manera de crear un diseño de paisaje correcto sí combina una serie de elementos de diseño tradicionales como masa, forma, línea, textura, color y otros. En el paisaje, estos elementos se utilizan para transformar el espacio y crear una experiencia única. Si bien el color y la textura agregan interés y riqueza a un diseño, la masa, la forma y la línea son fundamentales para organizar el espacio y proporcionar estructura.
