When O2 binds to heme in hemoglobin, the ion is drawn into the plane of the porphyrin causing a conformational change that is transmitted to adjacent subunits enhancing the for additional O2 binding. Group of answer choices Fe2 ; affinity Mg2 ; folding Mg2 ; planarity Fe3 ; affinity

Answers

Answer 1

Answer: Fe2 ; affinity

Explanation:

Hemoglobin is the specialised protein which are present in red blood cells which gives it the ability to carry oxygen to the tissues and return carbondioxide from the tissues to the lungs.

The hemoglobin is made up of

--> a heme group: this consists of a ferrous iron ( Fe2) and a surrounding porphyrin ring.

--> globin.

As the haemoglobin molecule loads and unloads oxygen (O2) the individual globin chains in the hemoglobin molecule move on each other. When oxygen is unloaded the beta chains are pulled apart, permitting entry of the metabolite 2,3-diphosphoglycerate resulting in a lower affinity of the molecule for oxygen and higher affinity for carbondioxide.

Also, when the partial pressure of oxygen (PO2) in the blood is high, the beta chains move close together, O2 binds to heme in hemoglobin, the ion Fe2 is drawn into the plane of the porphyrin causing a conformational change that is transmitted to adjacent subunits enhancing the AFFINITY for additional O2 binding.

Sickle cell disease is a recessive trait which causes a deformation in red blood cells due to a mutation in the gene that codes for hemoglobin. Consider a father and a mother BOTH with the genotype Hh, where H is the normal hemoglobin gene, and h is the gene that codes for the defective hemoglobin. What percent of their children will have the genotype hh, which means they will have the full-blown disease?

Answers

Answer: Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.

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%

Answers

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.

The differences in the curves of the graphed data indicate that there were differences in the number of electrons produced in the three samples during the experiment. Discuss how electrons are generated in photosynthesis and why the three samples gave different transmittance results.

Answers

Solution:

Photosynthesis is a process by which green plants and vegetables prepare their food using carbon dioxide from the atmosphere, water from the soil and in the presence of sun light with the help of chlorophyll.

-- During photosynthesis process, electrons are originated from the chlorophyll and it absorbs the photons of light from the atmosphere.

-- the energies are passed inward from the pigments to pigments until they reaches the reaction center.

-- then the energy is transferred to the P680, thus boosting the electron to the high energy level.

-- this high energy electron then passes to the acceptor molecule and is replaced with the electron from the water.

-- this splitting the water releases oxygen in the atmosphere that we breathe.

-- the electron generation is proportional to the DPIP reduction light transmittance.

-- the decrease in the light availability decreases the electron quantity of the electrons which will be generated.

-- the boiling disrupts the functional structures.

       

In a college biology experiment, 50 mg of methane and 60 mg of sulfate are mixed in a closed container. What is the limiting reagent, and how much excess reagent remains when that species has been exhausted

Answers

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

¿De qué manera pueden complementarse la

Puntuados?

Answers

La teoría sintética

El redescubrimiento en 1900 de la teoría de la herencia de Mendel por el botánico y genetista holandés Hugo de Vries y otros llevó a un énfasis en el papel de la herencia en la evolución. De Vries propuso una nueva teoría de la evolución conocida como mutacionismo, que esencialmente eliminó la selección natural como un proceso evolutivo importante. Según de Vries (a quien se unieron otros genetistas como William Bateson en Inglaterra), en los organismos tienen lugar dos tipos de variación. Una es la variabilidad "ordinaria" observada entre los individuos de una especie, que no tiene consecuencias duraderas en la evolución porque, según de Vries, no podría "conducir a una transgresión de la frontera de la especie [es decir, al establecimiento de nuevas especies] incluso en las condiciones de la selección más rigurosa y continua ". El otro consiste en los cambios provocados por mutaciones, alteraciones espontáneas de genes que dan lugar a grandes modificaciones del organismo y dan lugar a nuevas especies: “La nueva especie se origina así de repente; es producido por el existente sin ninguna preparación visible y sin transición ”.

Muchos naturalistas se opusieron al mutacionismo y, en particular, los llamados biometristas, liderados por el estadístico inglés Karl Pearson, quien defendió la selección natural darwiniana como la principal causa de la evolución a través de los efectos acumulativos de variaciones individuales pequeñas y continuas (que los biometristas se supone que pasa de una generación a la siguiente sin estar limitado por las leyes de herencia de Mendel).

Revolution, pollution increased. At this time, scientists observed that the number of
light-colored moths decreased, while the number of dark-colore moths increased and
became more abundant in the population than the light-colored variety.
Which graph represents how natural selection acted on moth coloration during
the Industrial Revolution? The dotted line represents the original population and the
solid line represents the population after selection.

Answers

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.

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. What are benefits provided by biodiversity?

Answers

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:

Provision or supply:

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.

Regulation:

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.

Cultural:

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.

Answers

Answer:

GlnA will be overexpressed and the cells will have more glutamine than glutamate

Explanation:

Glutamine synthetase (glnA) is an enzyme involved in nitrogen metabolism that catalyzes the amidation of glutamate to glutamine. Moreover, the phosphorylated form of the NtrC response regulator protein (NtrC~P) acts as a transcriptional activator of genes associated with nitrogen metabolism, including glnA. NtrC~P exhibits 1-an enhanced DNA binding activity (increased oligomerization on the target DNA template) and 2-ATPase activity (oligomerization of the NtrC phosphoprotein), which are fundamental features for transcriptional activation. In consequence, it is expected that a higher level of NtrC~P (due to a defective form of the phosphatase that dephosphorylates NtrC~P) leads to the overexpression of glnA, thereby increasing glutamine levels and simultaneously decreasing glutamate concentration.
