Answer:

50% or 1/2

Explanation:

The probability of their 6th child being a girl would be 50% or 1/2.

During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.

                             XX    x    XY

       XX (female)   XY (male)   XX (female)   XY (male)

XX - 1/2 or 50%

XY - 1/2 or 50%

Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.

Answer:

[tex]\dfrac{dy}{dx}=\dfrac{4}{25}[/tex]

Explanation:

The given expression is :

[tex]y=\dfrac{(x-1)}{(x+3)}[/tex]

We need to find dy/dx at x = 2

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]

Put x = 2 in above expression

[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]

Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

Answer:

the ability to reproduce with one another and have fertile offspring.

Explanation:

An essential characteristic of the members of a given species is the ability to reproduce with one another and have fertile offspring. Thus, the correct option is C.

A species is a group of organisms which are living in an area with similar characteristics which are capable of exchanging genes and chromosomes and produce new organism similar to itself. The species are important as it maintains the equilibrium in the ecosystem.

A species can be defined as the largest group of organisms with the two individuals of the appropriate sexes can produce a fertile offspring, typically through sexual reproduction. The species can also be defined on the basis of their karyotype, DNA sequence, morphology, behavior or ecological niche.

Therefore, the correct option is C.

Answer:

False

Explanation:

A cell normally contains 23 pairs of chromosomes.

Answer:

The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

Carbon, oxygen, & hydrogen may all be elements found in ethanol, but when separated, they have completely different chemical compounds. They are pure elements where as ethanol is a mixture.

Answer:

Part A:

— Chlorophyll absorbs different wavelengths than chlorophyll does. 

— Chlorophyll does not absorb wavelengths that are green and yellow, which is indicated by a very low degree of the light absorption.

Part B: 

Photosynthetic Organisms are organisms capable of photosynthesis. Photosynthesis is greenery and other organisms using the energy from sunlight to synthesize foods from carbon dioxide and water. Leaving allophycocyanin to be the protein these plants and other organisms receive from the light. So for the process, in order for the plants to live they must be able to go through photosynthesis giving the plants the energy and proteins they need to produce food and to release oxygen into the environment.

Answer:

The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose wavelength is between about 400 nm and 700 nm.

Visible light from the sun appears white, but it’s actually made up of multiple wavelengths (colors) of light. You can see these different colors when white light passes through a prism: because the different wavelengths of light are bent at different angles as they pass through the prism, they spread out and form what we see as a rainbow. Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.

Photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others.

The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.

Although both chlorophyll a and chlorophyll b absorb light, chlorophyll a plays a unique and crucial role in converting light energy to chemical energy (as you can explore in the light-dependent reactions article).

All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria Because of the central role of chlorophyll a in photosynthesis, all pigments used in addition to chlorophyll a are known as accessory pigments—including other chlorophylls, as well as other classes of pigments like the carotenoids. The use of accessory pigments allows a broader range of wavelengths to be absorbed, and thus, more energy to be captured from sunlight.

Answer:

metaphase I

Explanation:

The cell cycle encompasses the series of processes that divides a cell into daughter cells. The cell cycle is made of mitosis and meiosis, which are the types of cell divisions. Meiosis occurs in two division steps namely: meiosis I and meiosis II.

The stages in these meiotic process are prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. Note that, meiosis I involves homologous chromosomes while meiosis II involves sister chromatids. According to this question, Chromosomes pair up in the PROPHASE I stage and remains paired in the metaphase I stage until the separate in the Anaphase stage. Hence, chromosomes will be paired up in the METAPHASE I stage.
