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:

Explanation:

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.

Climate and weather have a significant monopoly over whether or not a species will survive. Say if we put a plant that has to live in hot areas in a cold place. It will die because of the climate and weather in the area. Henceworth, the answer is B.

Answer:

CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.

0.040 g

Explanation:

Step 1: Write the balanced reaction for the methane anaerobic oxidation

CH₄ + SO₄²⁻ ⇒ S²⁻ + CO₂ + 2 H₂O

Step 2: Establish the theoretical mass ratio between the reactants

According to the balanced equation, the theoretical mass ratio of CH₄ to SO₄²⁻ is 16.04:96.06 = 0.1670:1

Step 3: Establish the experimental mass ratio between the reactants

50 mg (0.050 g) of CH₄ react with 60 mg (0.060 g) of SO₄²⁻. The experimental mass ratio of CH₄ to SO₄²⁻ is 0.050:0.060 = 0.83:1

Comparing both mass ratios, we can deduce that CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.

Step 4: Calculate the mass excess of CH₄

The mass of CH₄ that reacts with 0.060 g of SO₄²⁻ is:

0.060 g SO₄²⁻ 16.04 g CH₄/96.06 g SO₄²⁻ = 0.010 g CH₄

The mass excess of CH₄ is:

0.050 g - 0.010 g = 0.040 g

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).

Answer and Explanation:

Biodiversity composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.

Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.  

Ecosystem services

When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.

Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

Answer:

The correct answer is - Option B.

Explanation:

Before the Industrial Revolution, the light color moths were predominant so that they can blend in with the light-colored trees and lichens in their environment. After releasing coal smoke from factories, the trees became darkened, and the light-colored moths become an easy target for predator birds to spot.

Over time, the frequency of the dark moth increased due to they had a higher survival rate in habitats affected by the air pollution and it blends with darker coloration blended with the sooty trees. This is a shift in the population’s genetic variance toward the new, phenotype.

In graph B, light color moth frequency decreases, and after natural selection increases over time and after a decrease in evolution the dark color again decreases.

Explanation:

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.

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.

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.

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?

Explanation:

Due to technical problems, you will find the complete explanation in the attached files

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.
