When blood sugar rises, signals are sent to the liver to increase bile production is NOT an example of negative feedback as a tool in homeostasis.
What are three examples of negative feedback?Negative feedback systems work to maintain relatively constant levels of output. For example, the body maintains its temperature, calorie consumption, blood pressure, pulse, and respiratory rate based on negative feedback loops.
Is sweating negative feedback?Another example of negative feedback occurs when your body's temperature begins to rise and a negative feedback response works to counteract and stop the rise in temperature. Sweating is a good example of negative feedback.

A student described his new pet dog to his friends. Which part of his description identifies an acquired trait of his new
dog?
Answer:
You did not enter the description of the dog, which does not allow me to tell you specifically which characteristic of the dog is acquired, but I can help you. This is because the characteristics acquired are those that are not hereditary, that is, a stain on the dog's ear or a bruise on its paw, for example, are a type of acquired characteristics.
Explanation:
As you may already know, hereditary characteristics are those that are passed from parents to children, through genetic factors. However, not all characteristics that living beings have are inherited. This is because there are the acquired characteristics, which are created by the environment over time and which are not passed on to descendants.
If your dog went to the pet shop and received a pink paint on his coat there, this is an acquired characteristic. The same is true if your dog has a bruised foot, or if there is a spot on its ear that is not related to the dog's genes.

Explanation:
If species are not changing, is it true to say that natural selection is not happening? Explain your reasoning
Answer:
true
Explanation:
ki
Answer:
Species are changing, natural selection is happening
Explanation:
There are many small, unnoticeable changes occuring in animals everday. Depending on whether these changes are helpful or unhelpful, the animal and its special features, will either be eliminated (through the process of natural selection) or embraced by others. If the traits are helpful, and therefore more dominant/attractive, it will ultimately lead to a split off, more dominant group of animals that all have the same adaptation, which allows the animals to out perform others.
**The reason you can't always see natural selection is because it's often a slow process. Also, if an animal's mental or physical traits change for the worse, the animal doesn't always live a full life, and doesn't reproduce. If the animal with the new traits doesn't reproduce (because the traits are not helpful and therefore unwanted), then that animal's traits are not allowed in the environment.**
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.

The diagram shows one step in the process of protein
synthesis.
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.

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”

If a man has red-green color blindness, a sex-linked dominant trait, what is a possible genotype of his father? I. XR Y II. Xr Y III. XR XR IV XR Xr A. Only III B. I and III C. I and II D. I, III, and IV
Answer:
C
Explanation:
The possible genotype of his father is [tex]X^RY[/tex] and [tex]X^rY[/tex].
For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.
The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.
Hence, in this case, the father can either be affected for the same trait ([tex]X^RY[/tex]) or be free from it ([tex]X^rY[/tex]).
The correct option is C.

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.

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.

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.

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.

What is earthquake and its causes?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates.
