frequency of allele “a” is .77

Explanation:

hardy weinberg equation

p^2 + 2pq + q^2 = 1 or (A+a)^2

p^2 =  (AA)

2pq =  (Aa)

q^2 = (aa)

AA -> 15/100 = .15

Aa -> 25/100 = .25

aa -> 60/100 = .60

if p^2 = AA = .15 then A = √.15 = 0.38729833462 = .39

if q^2 = aa = .60 then a = √.60 = 0.77459666924 = .77

Explanation:

Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:

     \(2C_2H_6+7O_2 ---> 4CO_2+6H_2O\)

From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas.

Pest species include armyworm, usually located in America, Africa, Asia, and Europe. They affect mostly cereal crops. Some control involves introduction of predators because it is a biological form of control.

One major pest problem around the world is the armyworm, which affects various crops such as corn, wheat, and rice. The armyworm, which is the larval stage of the fall armyworm moth, is native to the Americas but has spread to other regions, including Africa, Asia, and Europe.

The armyworm causes significant damage to crops by feeding on the leaves, stems, and ears of plants. In severe infestations, the pest can completely defoliate a field, leading to reduced yields and even complete crop failure.

To control the armyworm, agriculturalists have employed a variety of strategies. One effective solution is the introduction of a predator species, specifically the parasitic wasp, Cotesia flavipes. These wasps lay their eggs inside the armyworm larvae, and the wasp larvae consume the armyworm from the inside out, effectively controlling the pest population. This approach is considered a form of biological control, as it utilizes natural predators to keep the pest population in check.

Another solution is the use of chemical pesticides, such as neonicotinoids, which are applied to crops to kill the armyworms. However, this method can have negative impacts on the environment, and can lead to the development of pesticide-resistant armyworm populations.

In Africa, the pest is a major problem and the solution is the integration of the use of pesticides with the introduction of the predator wasp, Cotesia flavipes. This combination of solutions has been effective in reducing the armyworm population, resulting in improved crop yields.

Overall, the armyworm is a significant pest problem that affects crops around the world, leading to reduced yields and crop failure. Introducing a predator species, such as the parasitic wasp, Cotesia flavipes, is an effective solution that controls the pest population without causing negative impacts on the environment. However, in some regions, integration with the use of pesticides is also needed for optimal control of the pest.

If scientists found a fossil in the middle layer that was 2 million years old, they would conclude that Earth is more than 2 million years old based on the presence of older rock layers and fossils in lower layers.

Fossils provide valuable evidence for dating the age of the Earth and its geological history.

The principle of superposition, a fundamental concept in geology, states that in undisturbed rock layers, the oldest rocks are found at the bottom, while the youngest rocks are found at the top.

By finding a 2 million-year-old fossil in the middle layer, scientists can infer that the lower layers, which were formed before the middle layer, are older than 2 million years. Additionally, the presence of upper layers, formed after the middle layer, would suggest that Earth's age exceeds 2 million years.

Scientists use various dating methods, including radiometric dating, to determine the age of rocks and fossils.

These techniques analyze the isotopic decay of certain elements present in the rocks or fossils to estimate their age.

Through these methods, scientists can establish a more accurate timeline of Earth's history, revealing an age far greater than the age of the specific fossil found in the middle layer.

Answer:

Explanation:

Four organic molecules make up all of the life on Earth. Organic molecules contain carbon and hydrogen chemically linked to one another in long chains, with carbon as the backbone and hydrogen atoms attached to the carbon atoms. These atoms' ability to attach to one another allows for the creation of innumerable compounds conducive to life. All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.

Nucleic Acids

The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively. They make the proteins that are present in almost every structure and perform almost every function in your body. DNA has a twisted ladder-like form, while RNA has many different shapes, depending on its function. DNA typically remains within the center, or nucleus, of a cell; RNA can travel throughout the cell to where it is needed. The backbones of both substances consist of alternating molecules of phosphate and sugar. Nucleotide bases make up the "rungs" attached to the backbone. Of the two types of nucleic acids, DNA is more stable, making it less likely to be broken down than RNA. Your genes are made up of DNA, and each gene provides the code for making a specific protein. RNA helps DNA to make these proteins.

Proteins

Proteins are probably the most versatile of all the organic molecules, making up many structures and executing various functions within organisms. Building blocks called amino acids make up proteins. About 20 different amino acids combine to form all of the various types of proteins on Earth. These amino acids all have almost the exact same composition; the only difference is the R group, which differs in each of the amino acids and gives them their uniqueness. When a protein is made, the protein comes together one amino acid at a time within the ribosome -- a structure that houses protein synthesis. Proteins have four levels of structure: The primary structure is the bonding of amino acids to one another; the secondary structure refers to the folds in certain areas within the protein; the tertiary structure is the ultimate three-dimensional look of the protein; and the quaternary structure consists of smaller protein subunits chemically bonded together to form a larger protein.

Carbohydrates

Carbohydrates comprise the largest number of organic molecules in organisms. Basically, carbohydrates are sugars; their origin can be traced to photosynthesis, the process by which organisms such as plants use sunlight to transform carbon dioxide and water into food. The simplest sugar is glucose, a molecule used to provide fuel for many types of organisms, including humans. The sugars found in foods include: fructose in fruits, galactose in milk, maltose in vegetables and sucrose in table sugar. The starch found in whole grains and vegetables is a complex carbohydrate made of chains of simpler glucose molecules. Your body contains an enzyme called amylase, which breaks down carbohydrates in the food you eat into glucose, which your cells can use as energy.

Lipids

Lipids, perhaps better known as fats, come in different forms in your body and contain the most energy of all the organic compounds. When your body burns lipids for fuel, you get more energy than if you burned the other organic molecules. In your body, fats perform many functions, taking the form of phospholipids and cholesterol, both important components of cell membranes; waxes that provide plants and animals with a protective layer; hormones that signal different functions in your body; vitamins that aid in different cell functions; and steroids, which are important in a number of physiological processes. Fats from animals tend to be more viscous than fats from plants.

1. A stereotype is a belief or an idea about a group of people that may not be true for everyone in that group. For example, someone might think that all girls like to play with dolls, but not all girls like dolls. Stereotypes can be hurtful because they can make people feel like they're being judged unfairly.

2. Racism is when someone treats someone else unfairly because of their race or skin color. It's wrong to judge people based on things like their skin color or where they come from because everyone deserves to be treated with kindness and respect.

3. Discrimination is when someone treats someone else unfairly because of things like race, gender, religion, or disability. Discrimination can take many forms, such as not hiring someone because of their race, or not letting someone play a game because of their disability. It's important to treat everyone with fairness and kindness, no matter who they are.

4. Conformity is when someone changes their behavior or beliefs to fit in with a group. For example, if everyone in a class is wearing a certain type of clothing, someone might feel like they need to wear the same thing in order to fit in. It's important to remember that everyone is unique and it's okay to be different. Being true to yourself is more important than fitting in with a group.

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.
