Answer:
See the answer below
Explanation:
(a) One of the inorganic sources of new plant mass for the light-grown plants is the atmosphere. The carbon in the form of carbon dioxide in the atmosphere is sequestrated into the body of the light-grown plants through a process known as photosynthesis. During this process, the inorganic carbon dioxide becomes fixed into the body of the plant through a series of steps that include both light-dependent and light-independent. The overall equation of the process is as below:
[tex]6CO_2 + 6H_2O + Light --> C_6H_1_2O_6 + 6O_2[/tex]
As more plant mass is being gained by photosynthesis, some of the gained mass is also being lost to energy generation through a process known as respiration. Respiration is like the complete opposite of photosynthesis but a gain in mass is still possible because the rate of photosynthesis is more than the rate of respiration in the light-grown plants.
(b) The chemical reaction that can be held responsible for the decrease in mass of the dark-grown plants is respiration. Some of the mass is lost to energy generation and this mass cannot be recouped by adequate photosynthesis due to light limitation. The energy is needed to metabolic processes that would keep the plants alive. The equation of respiration is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + Energy[/tex]
Answer:
A) Inorganic source of cellular mass is CO2. Plants take up CO2 from the atmosphere. By the process of photosynthesis, plants prepare sugars . Sugar gets converted in to starch, cellulose and other carbohydrates which are stored in the cells of the plants. This increases the plant mass . Plant requires water,CO2, light chlorophyll.
Chlorophyll absorbs sun light and converts it in to chemical energy. Chemical energy is used by the plant to synthesize sugars. Because of the synthesis of the sugars ,starch etc , the mass of the plant increased. Plants need light for making sugars.
B. Decrease in the mass is due to cellular respiration. This group of plants are in dark. So they do not photosynthesis.
But they have to undergo respiration to get energy for the activities of the plant. So no photosynthesis is occurring, hence no sugar formation. But sugar present in the plant is consumed to release energy. That is why mass of the plants kept in dark is reducing.
Cellular respiration has 3 steps. 1. Glycolysis 2. Kreb's cycle. 3. Electron Transport Chain.
The cellar respiration provides energy to all living organisms.
[tex]C6H12O6 + 6 O2 ---------> 6CO2 + 6H2O + energy (ATP)[/tex]
CO2 released is given out of the plant body. So this is reducing the plant mass.

Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.

What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive
Answer: Polygenic recessive
Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.
This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).
What is Polygenic inheritance?Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.
Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.
Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E.e. eschscholtzii?
Answer:
E.e. oregonesis
E.e. platensis
E.e. xanthoptica
E.e. croceater
E.e. eschscholtzii
E.e. klaubori
Explanation:
The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.
Answer: none of the statements are true
Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.

What would happen if a cell couldn't make catalase?
Answer:
If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells
If hydrogen peroxide is not broken down by catalase, it can be converted into reactive oxygen species, which can damage DNA, proteins, and cell membranes.
What is catalase?Catalase is an important enzyme that uses hydrogen peroxide, a non-radical ROS, as a substrate.This enzyme breaks down and neutralizes hydrogen peroxide to maintain optimal molecular levels within cells.It is also essential for cell signaling processes. The catalase enzyme breaks down hydrogen peroxide (H2O2) into water and molecular oxygen, protecting cells from oxidative damage by reactive oxygen species.Commercially available catalase is produced from Aspergillus niger by a solid-state fermentation process.Peroxidase or catalase is an enzyme of the oxidoreductase class. The peroxidase enzyme catalyzes the breakdown of hydrogen peroxide into water and molecular oxygen as shown.Catalase is a tetrameric heme protein that detoxifies H2O2 into oxygen and water.It is a metalloprotein oxidoreductase and when present in high concentrations he efficiently removes H2O2.To learn more about catalase, refer
