• Write the biofuel and biogas chemical formulas. Explain why biofuel and biogas are still considered energy-dense molecules. Compare the chemical makeup of each component to carbon dioxide, which is produced when glucose is completely oxidised.
Answer:
diesel fuel is C12H23 whereas Methane is CH4.
Explanation:
The chemical formula for common diesel fuel is C12H23 while o the other hand, the formal of biogas such as Methane which is CH4. Both are organic compounds due to the presence of hydrogen and carbon. Biofuel and biogas are still considered energy-dense molecules because they have more mass and produced large amount of energy from it. The main difference between Carbondioxide gas and biofuel is that there is no hydrogen present in the formula of carbondioxide gas.

What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group
Complete question:
Question 49 (1 point) The following questions refer to the description below. You have read that soapberry bugs, Jadera haematoloma, adapt to available food sources. For example, in southern Florida, soapberry bugs feed on seeds of a native plant, the balloon vine. In central Florida, the balloon vine is rare and soapberry bugs have switched to eating seeds of an introduced species, the golden rain tree. The seeds of the golden rain tree fruits are much closer to the fruit surface than the seeds of the native balloon vine fruit. As a result, natural selection results in beaks that are shorter in soapberry bugs that utilize golden rain tree fruits than those that feed on balloon vine fruit seeds.
What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group?

Answer: Transcription bubbles
Explanation:
A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day.
Does this ecosystem follow Lindeman's Law for ecological efficiency?
a. Yes, the average efficiency is 20%
b. Yes, the average efficiency is 10%
c. No, the average efficiency is 20%
d. No, the average efficiency is 10%
Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
Yes, the energy available to all trophic levels is in the average of 10% which
follows Lindeman's Law for ecological efficiency.
Lindeman's Law for ecological efficiency states that the energy transfer from
one trophic level to the other should have a 10 percent efficiency. The
trophic level starts with the primary producers having more energy and the
tertiary consumers having the least amount of energy.
The example given shows that the different trophic levels in the ecosystem
have about 10 percent efficiency during energy transfer and availability.

g DNA sequences that are deduced by comparing many related DNA sequences are called _____________. [ Choose ] Unlike DNA synthesis, RNA synthesis requires ______________. [ Choose ] ______________ direct RNA polymerase to the initiation site.
Answer:
consensus sequences; no primer; promoters
Explanation:
In bioinformatics, consensus sequences refer to sequences (i.e. DNA, RNA, or amino acids) that represent aligned related sequences (usually evolutionarily conserved sequences). In DNA, consensus sequences may evidence putative DNA binding sites. Transcription refers to the process of RNA synthesis by using as a template a DNA sequence. The start of DNA synthesis requires a primer (i.e. a short oligonucleotide sequence with an available hydroxyl group on the pentose sugar), whereas RNA synthesis requires no primer. Finally, promoters are DNA sequences that determine the site in which transcription of a gene by the RNA Polymerase begins. Promoter sequences are located near the transcription start site (TSS) at the 5'-end of a gene sequence, and range in size from 100 to 1000 base pairs (bp).
Which of the following is the most susceptible to damage by pollution in the air and
precipitation
A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers
Answer:
B) Trees at high elevations
Explanation:
The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.
The tree leaves, which are the main key to the tree's photosynthesis, absorb the oxygen and Co2 from the air, which are converted into nutrients. Without proper nutrients, the trees may die out.
Which statement is true of human cultures? O A. All human societies share the same cultural traits and practices. O B. Every human has a unique set of cultural traits and practices. O C. Culture includes a society's knowledge, customs, and achievements. O D. Cultures are groups of people united by blood relationships. SUBMIT
Answer:
B. Every human has a unique set of cultural traits and practices.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.
This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.
The button-like structure that holds homologous chromosomes together at their middles during cell division is called the
Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.

Observe: Hold your cursor over one of the insects. The two rod-like structures under Genotype on the right side of the Gizmo represent chromosomes. The three letters next to each chromosome represent alleles. Which alleles does the insect have
Complete question:
Question: Where does variation in a population come from?
1. Observe: Hold your cursor over one of the insects. The two rod-like structures under the Genotype on the right side of the Gizmo represents chromosomes. The three letters next to each chromosome represent alleles.
Which alleles does the insect have? ____________________________________________
The alleles carried on an organism’s chromosomes make up the organism’s genotype
Answer:
Allele = WGenotype = WWW WWWExplanation:
First, you need to set red = 100, gree = 255, and blue = 50.You will see that the average fitness of individuals changed to 53%. Natural selection should be selected. Now, you need to click on any of the insects, and it will appear the chromosome on the right. You will see the word Genotype, and under it, you will see the chromatids.You will see that each chromatid has three alleles. Next to each allele, you will see which version of the gene is (W). In this particular example, all the alleles are the same, so all of them express white. Both chromatids carry only W alleles.
Think about alleles as an alternative form of the gene. So on this chromosome, we have only three genes but eight possible alternatives, which will be coding for white, red, blue, green, cyan, magenta, yellow, or black. The color expression will depend on the individual´s genotype.
In this case, the selected insect carries only the W allele, and its phenotype is white. The genotype of this insect is WWW WWW.
Note: If you click on any other insect, you will find the same genotype for all of them.
However, consider that depending on the environmental conditions and the selective pressures, these alleles might change. Individuals might carry other alleles that code for another color instead of having only W alleles.

How are igneous and sedimentary rocks similar?
Answer:
Igneous rocks form as magma cools below ground or lava cools on the surface. Sedimentary rocks are made from the eroded particles of other rocks or from mineral deposits left when water evaporates. Metamorphic rocks form when any existing rock undergoes intense and prolonged exposure to heat and pressure.
Explanation:
how scientists are able to determine climate information by just looking at tree rings? (how does it work?)
Explanation:
Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry.
Answer:
Explanation:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.
This apparatus can be used to show osmosis.
(a) Explain what happens to the level of sucrose solution in the glass tube. [3]
(b) Describe how this apparatus could be modified to measure the rate of osmosis at different temperatures. [3]
Answer:
A. The level of sucrose solution will rise in the glass tube because water molecules will pass through the semipermeable membrane into the tube as water potential is higher outside than inside the tube.
B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :
1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.
2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.
3. Using a stopwatch to record time taken for unit increase in the height of waterat different temperatures.
Explanation:
A. Osmosis is the movement of water molecules from a region of low solute concentration or high water potential to a region of high solute concentration or low water potential through a semipermeable membrane until equilibrium concentration is attained.
The movement of water molecules is based on a concentration gradient, from a region where there are more water molecules to a region where there are fewer water molecules.
The sucrose solution has a higher solute concentation but lower water potential due to fewer water molecules compared to water in the beaker, therefore, water molecules will pass through the semipermeable membrane into the glass tube resulting in an increase in the level of sucrose solution in the glass tube.
B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :
1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.
2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.
3. Using a stopwatch to record time taken for unit increase in the height of waterat different temperatures.
