5. A man heterozygous for a mutation in a gene that causes sickle cell disease (an autosomal recessive disease, i.e. not sex linked) who is color blind (a recessive X- linked condition) is expecting a child with a woman who is also heterozygous for the sickle cell disease gene. The woman has normal vision, but her father was colorblind. What is the probability that their child (of either sex) will have sickle cell disease AND be colorblind?

Answers

Answer 1

The probability that their child will have sickle cell disease and be colorblind would be 1/8.

Both diseases are independent of each other.

So, considering the sickle cell alone: Let A be normal cell and S for sickle cell. A heterozygous man and woman would both be AS.

                                     

                                    AS     x     AS

                                 AA   AS   AS   SS

Probability of their child having sickle cell = 1/4

Considering the color blindness alone, let a represents color blindness allele and A for normal eyes allele. A colorblind man would have [tex]X^aY[/tex] genotype while a woman with normal vision but with a colorblind father would be heterozygous with [tex]X^AX^a[/tex] genotype.

           [tex]X^aY[/tex]     x     [tex]X^AX^a[/tex]

          [tex]X^AX^a[/tex]   [tex]X^aX^a[/tex]  [tex]X^AY[/tex]  [tex]X^aY[/tex]

Probability of their child being colorblind = 1/2

The probability of their child having sickle cell and being colorblind = probability of having sickle cell x Probability of colorblind

                     = 1/4 x 1/2

                           = 1/8

por que es roja la sangre

Answers

La sangre es roja porque los glóbulos rojos contienen hemoglobina. Esta proteína (hemoglobina) es clave para transportar oxígeno a los tejidos.

Los glóbulos rojos, también conocidos como eritrocitos, son las células del torrente sanguíneo encargadas de transportar oxígeno y nutrientes a todas las células del cuerpo.

Los góbulos rojos contienen una proteína llamada hemoglobina que es la encargada de unirse al oxígeno obtenido durante al respiración y así transportarlo a los tejidos.

El color rojo se debe a la oxidación del grupo hemo de la hemoglobina, así de este modo la sangre adopta un color rojo más intenso cuando este grupo está más oxidado.

El grupo hemo es un grupo prostético el cual contiente un ion ferroso (Fe2+). Este grupo se encuentra en diferentes proteínas, especialmente la hemoglobina.

Photosynthesis is the process in which cells use oxygen to break down food and release stored energy. true or false

Answers

Answer:

false

because photosynthesis is the process of making food by green plants...

Answer:

False

Explanation:

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Answers

Answer:

hopefully this helps

Explanation:

Plants have similar cells to animals but two cells that plants have that animals don't is chloroplasts and plastids. The chloroplasts allow the plant to capture the energy of the sun. The plastids make or store important chemicals that are used by a plant. Both of these help the plant in different ways like plastids they often store photosynthesis which a plant needs to live and grow. Chloroplasts are also very important because it allows the plant to have a rigid structure which allows plant cells to change in size.

Answers

Answer:The geosphere consists of the core, mantle and crust of the Earth.

The atmosphere contains all of the Earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.

The hydrosphere contains all of the solid, liquid and gaseous water on Earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found. Ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.

The biosphere is the collection of all Earth’s life forms, distributed in major life zones known as biomes: tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.

[1] Although the four systems have their unique identities, there is substantial interaction between them. Environmental scientists study the effects of events in one sphere on the other spheres. For example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows:

Example 1 (Volcano) On May 18, 1980, Mount Saint Helens, in the state of Washington, erupted. This event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere. Such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. The following are but a few of the myriad of interactions resulting from a volcanic eruption.

Volcano >> geosphere >> atmosphere >> hydrosphere >> biosphere

Volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. These particles serve as nuclei for the formation of water droplets (hydrosphere). Rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere). Particulate matter in the air (atmosphere) falls out, initially smothering plants (biosphere), but ultimately enriching the soil (geosphere) and thereby stimulating plant growth (biosphere).

Volcano >> geosphere >> hydrosphere >> biosphere

Volcanoes (events in the geosphere) may release a substantial amount of hot lava (geosphere), which causes mountain glaciers (hydrosphere) to melt. Mudflows (geosphere) and flooding may occur downstream from volcanoes and may inundate streamside communities (biosphere).

Volcano >> geosphere >> atmosphere >> biosphere >> geosphere

Volcanoes (events of the geosphere) release a large amount of carbon dioxide (atmosphere), the raw material for sugar production in plants (biosphere). This may increase photosynthetic production and eventually increase the amount of biomass, which, after a very long time, forms coal and oil deposits (geosphere).

Volcano >> complex interactions

Volcanoes (geosphere) may emit large quantities of sulfur dioxide (atmosphere). When atmospheric sulfur dioxide combines with water (hydrosphere), sulfuric and sulfurous acid form. Rain (hydrosphere) may bring these acids to the Earth, acidifying soils (geosphere), lakes and rivers (hydrosphere). Acidic water leaches nutrients from the soil (geosphere) into the water table (hydrosphere), making the soil less fertile for plants (biosphere), and the subterranean water supply (hydrosphere) less potable for humans (biosphere). Acid rain falling on lakes and streams reduces the pH of the water (hydrosphere), which may result in a decrease in phytoplankton and zooplankton growth (biosphere). If photosynthesis is reduced, atmospheric concentrations of carbon dioxide can build up and stimulate global warming (atmosphere) which may contribute to increased melting of glaciers (hydrosphere)

Explanation:

Both the mining and burning of fossil fuels are interactions between geosphere and biosphere which damages the atmosphere. Thus, correct option is B.

What is atmosphere?

The atmosphere contains air which is a blanket of gases that surrounds the planet- Earth and the gases that we breathe. The atmosphere is held in the position near the Earth surface by gravitational attraction. A barometer is an instrument used to measure the air pressure. Argon, oxygen and nitrogen are some of the main gases which constitutes the atmosphere.

The geosphere of Earth consists of core, mantle and crust of the planet. The atmosphere consists of all Earth's air, gases and it is divided into different zones on the basis of height i.e., troposphere, stratosphere, mesosphere, thermosphere and ionosphere.

The atmosphere provides geosphere, all the heat and energy required for the breakdown of rock and erosion. The biosphere of Earth receives all the gases, heat, energy, and sunlight from the atmosphere.

Therefore, correct option is B.
