Explanation:
Assume there are 500 units of energy in the producer level of the energy pyramid. How many units of energy are available at the first level consumer store? How many units will be at the 2nd level consumers store?
Only about 10% of the energy from each trophic level is transferred to the following level in an energy pyramid. This implies that only 10%, or 50 units, of the energy accessible at the first level consumer level, if there are 500 units of energy at the producer level.
Similar to this, only 10%, or 5 units, of the 50 units of energy at the first level consumer level would be accessible at the second level consumer level.
Therefore, the amount of energy at each trophic level would be:
Producer level: 500 units of energyFirst level consumer: 50 units of energySecond level consumer: 5 units of energyLearn more about trophic level, here:

What characteristic was used in this mission to determine a banana's relationship to other the plants?
The characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics.
What is morphology?
Morphology is the study of the form and structure of living organisms, including their physical and anatomical features. In biology, morphology is used to describe the appearance, shape, and size of different parts of an organism, such as its organs, tissues, cells, and even its molecules. This includes the study of external and internal structures, as well as their function, development, and evolution. Morphological characteristics are often used in the classification and identification of different species, as they can provide important clues about an organism's evolutionary history, ecological niche, and relationship to other organisms.
We assume you are referring to the scientific classification of bananas in the plant kingdom. In this case, the characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics. Bananas belong to the genus Musa, which is part of the family Musaceae.
The characteristics used to classify plants into different taxonomic groups include their structural features, such as their leaves, stems, flowers, and fruit, as well as their genetic and evolutionary relationships. These characteristics are used to group plants into increasingly broader taxonomic categories, from species to genus, family, order, class, phylum, and kingdom.

While working in a genetics lab over the summer, you isolated a true-breeding strain of wingless Drosophila. After sharing your results with your mentor, you learn that six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in your lab. Your mentor asks you to determine if the mutants belong to the same complementation group. What is true about flies that belong to the same complementation group?
a. They all have the same mutation in the same wing- development gene. All flies in a complementation group have identical DNA sequences for this gene.
b. They all have some mutation in the same wing-development gene. Each strain may have a different mutation, but the same gene is mutated in all trains in a complementation group.
c. They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Answer:
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.

In humans, mid-finger hair is dominant to no mid-finger hair. A woman who has no finger hair wants to marry and have children with a man who does have mid-finger hair. they do not know his genotype though. determine the likelihood that they have a child with no finger hair like their mom. Include all possible options.
The likelihood that they will have a child with no finger hair like their mother depends on the man's genotype. If the man is heterozygous (Hh), there is a 50% chance that they will have a child with no finger hair. If the man is homozygous dominant (HH) or homozygous recessive (hh), all the offspring will have mid-finger hair.
Dominant Mid-Finger HairIf the woman does not have any mid-finger hair, it means she is homozygous recessive (hh) for this trait. The man, on the other hand, may be homozygous dominant (HH), heterozygous (Hh), or homozygous recessive (hh) for the trait, but we do not know his genotype.
Let's consider all possible options for the man's genotype and the resulting probabilities for their offspring:
Option 1: The man is homozygous dominant (HH) for mid-finger hair.In this case, all the offspring will be heterozygous (Hh) and have mid-finger hair. None of the offspring will have no finger hair like their mother.
Option 2: The man is heterozygous (Hh) for mid-finger hair.In this case, half of the offspring will be heterozygous (Hh) and have mid-finger hair, and the other half will be homozygous recessive (hh) and have no finger hair like their mother.

Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

For both the plots with the beetles added and the control plots, state the mean tree leaf area per plot that the scientists recorded after running the experiment for 18 months
For both the plots with the beetles added and the control plots. The mean tree leaf area per plot that the scientists recorded after running the experiment for 18 months with the beetles added is 1.7 m², and for the control plots is 2.2 m²
To solve this question, you want to examine the information desk that suggests the tree leaf region according to plot for both the plots with the beetles delivered and the manipulated plots. The implication is the commonality of the statistics values, which can be found by adding up all of the values and dividing by the range of values.

If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain
Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.
Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.
Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.
For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.
