Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)
Answer:
Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.
Answer:
honey bees Extinction types are parasites ,habitat loss ,and cell phones. but there two main types of parasites that are harming the honeybees are Vero mites and tracheal
b. gene; DNA strand; chromosome; genome
c. DNA strand; gene; genome; chromosome
d. gene; chromosome; DNA strand; genome
e. DNA strand; chromosome; gene; genome
Answer:
b. gene; DNA strand; chromosome; genome
Explanation:
The smallest unit in genetic structure will be gene which is a segment of DNA. After that comes DNA strand which may contain one or more genes. A chromosome is a larger structure as compared to a DNA strand because a chromosome contains two DNA strands which are joined at centromere. All the chromosomes in an individual collectively form genome so genome is an even larger term when it comes to genetic information.
Genetic information can be organized from smallest to largest as follows: DNA strand, gene, chromosome, and genome. The correct answer from your list is 'b'.
The levels of genetic information, organized from smallest to largest, are as follows: DNA strand, gene, chromosome, and genome. Let's break it down step by step:
Therefore, the correct answer from your list would be option 'b': gene, DNA strand, chromosome, genome.

Answer:
An Inherited behavior is a behavior received from the parents through genetics such as long legs for speed while a learned behavior is a behavior in wich an animal has to learn by itself by looking at past experiences such as baby ducks learning how there mother duck avoids danger.
Explanation:
Answer:
A learned behavior is more a behavior that is learned from experience of an organism. An example is imprinting, in which a young animal comes to recognize (another animal, person, or thing) as a parent or other object of habitual trust.
An inherited behavior is one that is innate, something that is bestowed upon an organism at birth. An example is animals starting to instinctually prepare for winter as the weather turns cold during the fall.
Bill needs to solve a system of linear equations based on the nutritional content of each food item in order to find out how many cups of rice, tofu, and peanuts he should consume to meet his specific nutritional goals. Keep in mind the caloric density of foods and the importance of a balanced diet.
To determine the number of cups he should eat, we would first need to set up a system of linear equations based on the nutritional content of each food item.
Let's denote R as the number of cups of rice, T as the number of cups of tofu, and P as the number of cups of peanuts. From the information given, we can create these equations:
42R + 4T + 34P = 350 (for carbohydrates)
0R + 11T + 75P = 311 (for fats)
1R + 23T + 35P = 168 (for proteins)
He needs to solve this system of equations to get the values of R, T, and P. Keep in mind, nutritional goals are important but it's also vital to consume foods high in micronutrients, fiber and have a balanced diet. Remember that fatty foods are calorie-dense compared to carbohydrates and proteins, meaning they have more calories per unit mass. This can be a healthy and sustainable meal plan for Bill if he also incorporates sufficient fruits, vegetables, and exercises regularly.

Answer:
Plants and animals assimilate carbon-14 from carbon dioxide throughout their life. When they die, they stop exchanging carbon with the biosphere and their carbon-14 content begins to decrease at a rate determined by the law of radioactive decay.
Radiocarbon dating is basically a method designed to measure residual radioactivity.
Explanation:
Carbon-14 is a weakly radioactive carbon isotope; It is also known as radiocarbon, and is an isotopic stopwatch.
Radiocarbon dating is only applicable to organic materials and some inorganic materials (not applicable to metals).
Proportional gas counting, liquid scintillation counting, and accelerator mass spectrometry are the three main methods of radiocarbon dating.
The radiocarbon, or carbon-14, is an isotope of the carbon element that is unstable and weakly radioactive. The stable isotopes are carbon-12 and carbon-13.
Carbon 14 is continuously formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen-14 atoms, rapidly oxidizing in the air to form carbon dioxide and entering the global carbon cycle.
Accelerator mass spectrometry (AMS) is a modern method of radiocarbon dating that is considered the most efficient way to measure the radiocarbon content of a sample. In this method, the content of carbon-14 is measured directly in relation to carbon-12 and carbon-13 present. The method does not take into account beta particles, but the number of carbon atoms present in the sample and the proportion of the isotopes.
