Jobisdone [24]3 years ago

Cell Hypothesis is one of the fundamental standards of science. Credit for the plan of this hypothesis is given to German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.

Cells need nutrition in order to get the required elements. Which specific foods provide specific elements, and what do those elements do in the cell?

...

The major macromolecules are:

carbohydrates and lipids - made of carbon, hydrogen, and water.

proteins - provide nitrogen and sulfur.

nucleic acids - provide phosphate.

In science, cell hypothesis is the notable logical hypothesis, presently generally acknowledged, that living life forms are comprised of cells, that they are the fundamental basic/hierarchical unit everything being equal, and that all cells originate from prior cells.

Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.

A woman, S.R., had a maternal grandfather with hemophilia A (OMIM 306700), an X-linked recessive condition that reduces blood cl
Sidana [21]

Answer:

Hemophilia is a x-linked recessive inherited bleeding  disorder. in this disease blood does not clot properly due to the decreased level of blood clotting factor VIII (8) or factor IX (9).

In x-linked recessive condition, the disease is transmitted from father (affected male) to his daughter and mother (affected female) to her son and skip of generation getting affected is also occurs.

  • there will be 50% chance of her (S.R.) each son to be affected with hemophilia.

Explanation:

Hemophilia is caused due to mutation of one gene which is responsible for the making of proteins of  blood coagulation factor viii or ix. the affected person bleeds continuously from any injury and that can cause serious issues.

here,

grandfather of s.r is affected (xₐy) and grandmother is normal (xx) will produce

                                                   ↓

 s.r's mother who is a carrier (xₐx) [as xₐy and xx will produce 100% carrier xₐx daughter]

                                                    ↓

s.r's mother is a carrier (xₐx) but her father is normal (xy) will produce,

                                                   ↓

s.r who has 50% chance of being carrier (xₐx) and 50% chance of being normal (xx) [as she is the only child] and she has a normal (xy) partner, they will give,

                                                     ↓

  1. if s.r is a carrier (xₐx) then one of her son will be affected (xₐy)   [as xₐx and xy =xₐy]
  2. if s.r is normal (xx) then her son will be normal (xy) [as xx and xy will give xy]

here,<u> 50% chance of her son to be affected with hemophilia</u> [as S.R of being affected is more considerable].
