Answer:
Population bottleneck
Explanation:
Population bottleneck can be defined as a sharp decrease in a population size which can be attributed to various environmental influences including fires, hurricane, famines etc.
This leads to loss of alleles and a small population. With a smaller population size, celebrities mutations can occur, producing several inherited disorders.

An individual who is heterozygous for two linked genes (with alleles A, a and B, b) is crossed with an AB/ab individual, and among the progeny are: 14 AB/ab 36 Ab/ab 34 aB/ab 16 ab/ab What is the frequency of recombination
Answer:
The correct answer is - 0.30
Explanation:
In case of the same alleles, there will be only one type of gametes as there is no repulsion takes place while in heterozygous 4 types of gametes will form due to repulsion.
Always less number shows recombinant. A higher number shows parental. Since the linkage is possible just when removing between the gens is under 50 So, the number of recombinants are:
16+14 = 30
then:
Recombination recurrence = number of recombinants/Total offspring
Recombination Frequency = 30/100 = 0.30
Thus, the correct answer is - 0.30

Biodiversity serves many ecological functions that are important to the
biosphere. Which of these is an example of such a function?
A. Removing atmospheric oxygen
B. Decreasing biological productivity
C. Increasing erosion
D. Recycling nutrients
Answer:
The answer should be D, recycling nutrients
Explanation:
One important aspect of Biodiversity is nutrient storage and cycling, performed throughout the ecosystem. Through atmostpheric elements in addition to those in the soil, this function maintains stability and life on the planet. A and D are wrong because they harm the environment, and B is incorrect because biological diversity is actually essential. Thus, D is correct.
Answer:D
Explanation:Recycling helps preserve biodiversity by limiting the amount of resources needed to make new products.
7. List all the possible different gametes that could be produced from the following parents:
a. Tt
b. GG
с. ff
Answer:
a. Tt - Gametes T and t
b. GG - Gametes G only
с. ff - Gametes f only
Explanation:
Gamete formation or meiosis is a cellular division of the reproductive cells in sexually reproducing organisms. Meiosis produces daughter cells (gametes) with a reduced number of chromosomes (by half) as the parent cell.
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene get separated into gametes in such a way that only one allele can be found in the gamete. The separation is random and equal.
Based on this, a heterozygous parent Tt will produce gametes with alleles T and t in an equal proportion. Since parents GG and ff contains the same alleles in their genotype, they will produce gametes with only one type of allele each i.e. Gametes with alleles G and f respectively.

Consider aerobic cellular metabolism from the beginning to end. What is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and ATP?
Explanation:
This starts with substrate level phosphorylation(glycolysis) in the cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of 4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.
The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.
The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.
Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2 are produced.These takes place in the mitochondria.
Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.
The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across the walls of mitochondria into the intramembrane space.
The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.
Answer:
The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are 32ATPs per molecule of glucose splits in Glycolysis.

"My mistress"

"damask'd"
Read Shakespeare's "Sonnet 130."
My mistress' eyes are nothing like the sun;
Coral is far more red, than her lips red:
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses seel in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound:
I grant I never saw a goddess go,
My mistress, when she walks, treads on the ground:
And yet by heaven, I think my love as rare,
As any she belied with false compare.

which words in the sonnet indicate that the tone is satirical ?
Answer:
"black wires"
"reeks".
Explanation:
William Shakespeare's "Sonnet 130" is a satire or mocking critique of the conventional sonnets that writers write. In this sonnet, he talks of a young lady who is short of conventional beauty ideals.
In the given lines from the sonnet, the poet/ speaker talks of his mistress whose "eyes are nothing like the sun" and he keeps on describing her features as opposed to one praising his lover. Rather, the speaker in this sonnet uses the negative descriptions in describing his mistress, like calling her hair "black wires" and her breath "reeks", far from the delightful perfumes that a lady is supposed to exude.
Thus, the two words that have a satirical tone in the sonnet are "black wires" and "reeks".
Answer: “black wires” and “reeks”

Functions of: [A] nucleolus [B] plasma membrane.
Answer:
The nucleolus is considered as the brain of the nucleus. It occupies around 25% of the volume of the nucleus. It is mainly involved in the production of subunits which then together form ribosomes. Therefore, nucleolus plays an important role in protein synthesis and the production of ribosomes in eukaryotic cells.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

RNA polymerase
DNA strand
Answer:
its transcription
Explanation:
The process shown in the diagram is called transcription.
Transcription represents the first stage of protein synthesis. During this process, genetic information on DNA templates are transcribed to genetic codes in the form of messenger RNA.
The transcription process starts with the binding of the RNA polymerase enzyme to the promoter region of a gene. This causes the unwinding of the double helix structure of DNA in the binding region. Thereafter, the RNA polymerase starts synthesizing the complementary bases of the DNA template.

Explanation:
Cell division is preceded by two growth phases. Besides growth, both G1 and G2
Answer:
A
Explanation:
a. contain checkpoints that determine if the cycle will continue.
b. help move chromosomes to the new daughter cells.
c. produce more chromosomes before the cell divides.
d. grow and produce enough cytoplasm to fill two cells.
The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.
The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.
At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.
At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.
At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.
The correct option is therefore, A.
