What is biodiversity? Please explain. I’ll give literally anyone branliest...I NEED HELP ASAP!
Answer: Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem levels. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Explanation:
Answer:
The variety of life in the world or in a particular habitat or ecosystem. (It is a noun).
Explanation:
Jose is growing pea plants in his garden. He notices that some plants have green pods, while others have yellow pods. He researches the species he planted and finds that green pods are dominant to yellow pods.
According to Mendel's law (principle) of dominance, which of the following statements can be said with certainty?
Answer:
The yellow pods will be destroyed.
Explanation:
His law states that one of the species will be completely destroyed if one is dominant. His guinea pig example illustrated this. The guinea pig was the framework of his principle, and relates almost exactly to this situation, except for the pods and pigs difference.
Answer:
- The plants with yellow pods do not have an allele for green pods.
- The plants with green pods might be homozygous or heterozygous for pod color.
Explanation:
Gregor Mendel's law (principle) of dominance states that some alleles are dominant, whereas others are recessive. An organism with a dominant allele for a particular trait will always have that trait expressed, or seen, in the organism. An organism with a recessive allele for a particular trait will only have that trait expressed when the dominant allele is not present.
The question states that Jose's pea plants can have two forms of the pod color allele—a dominant green allele and a recessive yellow allele.
His plants with yellow pods must be homozygous for the recessive yellow allele. Therefore, the plants with yellow pods cannot have an allele for green pods.
His plants with green pods could have two alleles for green pods or one allele for green pods and one for yellow pods. Mendel's law of dominance states that an organism needs only one copy of the dominant allele for its trait to be expressed. So, the plants with green pods might be homozygous or heterozygous for pod color.
Incomplete dominance is a condition in which one allele is not completely dominant over another, resulting in a phenotype (outward appearance) somewhere between the two homozygous forms. Since it is known that green pods are dominant to yellow pods and no other pod colors were produced in Jose's garden, it can be concluded that the plants are not displaying incomplete dominance.

While eating a piece of fruit, a group of scientists noticed that some had fruit that was spoiled while others didn't. One scientist said they left their fruit on the counter, another left theirs in the fridge, and one left theirs in the freezer. They decided to conduct an experiment to determine where fruit should be stored so it stays fresh longer. The fruit of choice was granny smith apples that were bought at the same time and were the same size. One apple was left on the counter, another in the fridge, one in the freezer, one was left outside on a porch, and a final apple was left in the microwave. All remained in their locations for one week and they tested which apple was freshest. In this experiment, what is the independent variable? A. Type of apple B. Where the apples were left C. Amount of time apples were left out D. Freshness of apple
Answer:
"where the apples were left"
Explanation:
In the scenario being described the independent variable would be "where the apples were left". This is because where the apple was left does not depend on any other factor for the results to be affected. The freshness of the apple would be the dependent variable because it depends on where the apple was left and for how long, while the amount of time is the controlled variable in this scenario because it remains constant for all groups and was chosen by the scientists.
What is the energy Molecule used by all cells? How does it cycle?
Eukaryotic cells use three major processes to transform the energy held in the chemical bonds of food molecules into more readily usable forms — often energy-rich carrier molecules. Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells.

A population of kangaroos have a gene with two alleles that affects birth weight. AA individuals are much heavier at birth. Aa individuals are medium size at birth and aa individuals are very small at birth. Large babies sometimes die during the birth process and very small babies often die from illness. Show the selection that you think is taking place on the population
Based on the process of natural selection, individuals with genotype Aa are naturally selected for survival.
What is natural selection?Natural selection is the process by which individuals who possess features or structures best suited for survival in their environment are selected for survival.
In the population of kangaroos having a gene with two alleles affecting birth weight, it is observed that individuals with Aa geneotype for medium birth weight survive.
Therefore, individuals with genotype Aa are naturally selected for survival.

In domestic swine there is a dominant allele which produces a white belt around the body. The recessive allele produces uniform body color. One farmer wants to produce only belted hogs, and another wants only uniformly colored animals. Which farmer would have an easier time producing a true-breeding herd? Explain why. Tell how each farmer would proceed. (Hint: how could you tell if a herd was true-breeding?)
Answer:
The first farmer
Explanation:
The belted allele is dominant and would therefore have a higher chance of showing up in the hog.

1. releases bile to break down fat lungs 2. helps break down protein small intestine 3. remove carbon dioxide from the body liver 4. breaks down starch into sugar large intestine 5. absorbs nutrients into the blood pancreas 6. absorbs extra water from undigested food saliva
Answer:
1. Liver
2. Pancreas
3. Lungs
4. Saliva
5. Small intestine
6. Large intestine
Explanation:
1. Liver is a large, infact the largest, organ found in the digestive system. It has variety of functions ranging from detoxification to digestion. The liver functions in digestion by secreting a substance called BILE which helps in the breakdown of fat in the small intestine.
2. Pancreas is another accessory digestive organ which serves as a endocrine organ which secretes enzymes that aid in the digestion of protein and carbohydrate molecules.
3. Lungs are respiratory organs whose function is key to the respiratory system. They are the organs that serve as a medium of the entry of oxygen and removal of carbon dioxide, a process called GAS EXCHANGE.
4. Saliva is a liquid substance secreted by the salivary gland in the mouth. Saliva contains certain enzymes; most notably is the AMYLASE that breaks down starch into sugar.
5. Small intestine is another organ in the digestive system composed of the ileum, jejenum and duodenum. The small intestine is the organ where the absorption of nutrients into the blood from the digested food takes place.
6. Large intestine is the extension of the small intestine whose function is to absorb extra water from undigested food and pass out the remaining as feaces.

Hypothesis: Increasing water temperature had no effect on the fermentation rate of yeast. Experiment: Compared yeast in room-temperature (22°C) water to yeast in lukewarm (45°C) water. Measured CO2 production. What statement is the most appropriate conclusion for David to write?
Answer: If the temperature of the water bath rises then the rate of carbon dioxide production will also rise.
Explanation:
Yeast is a eukaryotic cell and it belongs to the kingdom fungi. It conducts the chemical reactions involved in alcoholic fermentation. At the higher temperature, the chemical bonds of the enzyme involved in the alcoholic fermentation may break. Thus, with the increase in temperature of water the enzyme will not carry alcoholic fermentation and the rate of fermentation of yeast will decrease.
