Explanation:
which of these is a source for particulate matter in the air?
Answer:
Particulate Matter (PM) Sources Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.
Explanation:
Automobiles, dust, and fires are source for particulate matter in the air. Therefore option D is correct.
Particulate matter (PM) refers to tiny particles suspended in the air that can have harmful effects on human health and the environment. Sources of particulate matter in the air include automobiles, dust, and fires.
Automobiles emit exhaust emissions that contain particulate matter, especially from diesel engines. Dust particles can be generated from various sources such as construction sites, unpaved roads, and agricultural activities.
Fires, including both wildfires and controlled burns, release smoke and ash particles into the air. These particles can vary in size and composition.
All of these sources contribute to the presence of particulate matter in the atmosphere, and their emissions can have detrimental effects on air quality and public health if not properly managed or controlled.
Therefore option D all of the above is correct.

There is no way to produce tall offspring since both parents are homo-zygous recessive.
Explanation:
parent plants are short because neither of them has at least one dominant "S" gene. As both of them have recessive "s" genes, they are scientifically known as homo-zygous recessive organisms. So produced offspring will never be tall as they don't have the dominant "S" gene transmitted from their parents. this is genotypically expressed as below.

A process common to all living organisms, whether aerobic or anaerobic, is glycolysis as part of the metabolism of all living organisms.
Glycolysis is the universally distributed metabolic pathway in all organisms and cells, by means of which a glucose molecule is degraded to two pyruvate molecules, in addition to producing energy in the form of ATP and NADH.
Specifically, ATP is the only high-energy phosphate that is formed primarily from the energy gain of the cell through oxidative processes (aerobic) or glycolysis (aerobic or anaerobic).
Glycolytic enzymes are located in the cytoplasm, near the contractile filaments, therefore, the ATP produced by the glycolytic pathway is formed near the place where it is used.
Phases:
Preparatory: Four reactions: two are phosphorylation and consume 2 ATP per glucose molecule. The breakdown of hexose produces 2 trioses, which end in 2 molecules of glyceraldehyde-3-P. .Oxidation of glyceraldehyde-3-phosphate (x 2) to pyruvate (x 2) and coupled formation of ATP in 2 of the reactions, in total 4 ATP and 2 NADH are formed.In aerobics glycolysis consists of extracting energy from organic molecules from the oxidation of carbon by oxygen.
In anaerobic glycolysis the element used to achieve oxidation is not oxygen but sulfate or nitrate.
Therefore, we can conclude that a process common to all living organisms, whether aerobic or anaerobic, is glycolysis as part of the metabolism of all living organisms.

Explanation:
Amino acids form peptide bonds through dehydration. Explain the role of water in this process by describing the chemical reaction.
Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Explanation:
Peptide bonds are- Any reaction that combines two monomers in a reaction that generates H2O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.

Answer:
B is the answer. Glucose and oxygen are given off during Photosynthesis
The cells in this leaf are making their own energy by the process of photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP.
Photosynthesis is critical for the existence of the vast majority of life on Earth. It is the way in which virtually all energy in the biosphere becomes available to living things.

1. A baby’s mass was measured when the baby was born and then every month for 6 months. At 3 months of age, the baby was sick, so the baby’s mass was not measured. Create a graph by using the data table above. Use the graph to find the likely mass of the baby at 3 months.
2. Does your graph show a linear or a nonlinear relationship? Explain your answer.
Answer:
1. 5.51 kg
2. A linear relationship, because the mass-time graph have the shape of a line

Known as the 'Pine Tree State; Maine's state tree is the Eastern white pine. Consider the model. Cärbon dioxide, water, and sunlight
are reactants of photosynthesis and are used to produce glucose and release water as a byproduct. What advantage does the pine tree
have in performing photosynthesis compared to deciduous trees such as oak or maple?
34)
A) Pine trees need less water to do photosynthesis.
B) Pine trees produce twice as much glucose as deciduous trees.
C) Pine trees do not lose their leaves and can photosynthesize all year.
D) Pine trees get more sunlight than oak trees due to their darker color.
Answer:
C) Pine trees do not lose their leaves and can photosynthesize all year.
Explanation:
In cold-temperate and Arctic regions, however, evergreens are typically cone-bearing shrubs or trees (conifers), such as pines and firs. Many tropical species of broad-leaved blooming plants are evergreen. Thus, option C is correct.
What are features of pine trees?Pine trees may photosynthesize in the winter because they retain their needles all year long! Compared to trees that lose their leaves, this is a significant advantage.
Their leaves therefore stay green and stay attached for a longer period of time than their deciduous counterparts because they can preserve more water.
However, because of their tiny surface area, needles are not as effective at absorbing the sun's energy.
Therefore, Pine trees do not lose their leaves and can photosynthesize all year.
