Identify the phases in the life cycle of small and big stars.
Answer:
The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.
Explanation:
You want to determine if gene X is a direct primary target of sigma S, or an indirect secondary target. To do so, you perform experiments with transcription and translation inhibitors and look for gene X RNA synthesis. Which experiment and result unambiguously points to gene X being a direct, primary target of sigma S
The question is incomplete,below is the complete question;
Regulons are collections of coordinately regulated genes and operons that can be controlled by alternating sigma factors such as sigma S,some of the genes and operons expressed in response to sigma S are primary targets that are directly bounded by sigma S,others are indirect, secondary targets of sigma S and are activated by a primary targets protein.
You want to determine if gene X is a direct primary target of sigma S, or an indirect secondary target. To do so, you perform experiments with transcription and translation inhibitors and look for gene X RNA synthesis. Which experiment and result unambiguously points to gene X being a direct, primary target of sigma S.
A) Experiment: transcription inhibitor Result: No gene X RNA production.
B) Experiment: translation inhibitor
Result: No gene X RNA production.
C) Experiment: transcription inhibitor
Result: gene X RNA production.
D) Experiment: translation inhibitor
Result: gene X RNA production.
The correct answer to the question is option A.
EXPERIMENT: TRANSCRIPTION INHIBITOR
RESULT: NO GENE X RNA PRODUCTION.
The protein that gives the specificity to RNA polymerase is known as a sigma factor. The specificity it gives is for RNA polymerase to bind at specific gene promoter sequence.
Here,we are looking at gene X RNA synthesis here by using transcription and translation as inhibitors.
Using inhibitor as transcription,there will not be transcription as well as translation occurance because translation occurs after the occurance of transcript (mRNA) synthesis through transcription.
However,if we decide to use inhibitor as translation,there will always be a chance for the synthesis of transcription that is gene X RNA production.
Both hexokinase IV and hexokinase I phosphorylate glucose at carbon-6. What properties of hexokinase IV make it important for maintaining stable blood sugar levels
I am going to explain the properties of hexokinase IV and it's properties that make it important for the maintainance of stable blood sugar level.
Hexokinase as well as Hexokinase IV all phosphorylate the glucose at C-6, Because Hexokinase IV has a low affinity with glucose and it is expressed in the liver,so it does have a way of maintaining blood sugar level.
When the blood glucose is low generally,it isn't saturated or working,but when the blood glucose gets high,it becomes transactivated and the activity of glucose 6 phosphatase results in low blood glucose.
Therefore,the most important activity of
Hexokinase IV is the regulation of blood glucose levels.

The sentence that describes the heterogeneous mixture is beach sand, a substance that can contain rocks, shells, metals and other substances distributed unevenly throughout. Thus, option C is correct.
What is rock?Rock has defined as when mineral grains are combined in the solid form and later grow or take shape of cemented form has been known as rocks.The rocks are made up of the more than one mineral and the size of some rocks are the small or big it depends upon their constituents. Rocks has been divided on the basis of their formation by Geologists.There are mainly three kinds of rock and these are metamorphic, igneous, and sedimentary. The most durable substance has been the stone.
Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.
Therefore, The sentence that describes the heterogeneous mixture is beach sand, a substance that can contain rocks, shells, metals and other substances distributed unevenly throughout. Thus, option C is correct.

WHAT'S THE DIFFERENCE BETWEEN INCOMPLETE DOMWANCE AND CO-ODOMINANCE ? GIVE EXAMPLES OF THE BOTH INCOMPLETE AND
CO-ODOMINACE. USE THE PUNNET SQUARE TO SUPPORT YOUR ANSWER
Answer/Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other, resulting in an intermediate phenotype. Example could be in flower colour. F is the allele for red flowers, f is the allele for white flowers. Let's cross a red flower (FF) with a white flower (ff):
F F
f Ff Ff
f Ff Ff
100% of the offspring are Ff. F is in completely dominant to f, so all the offspring have an intermediate phenotype - all the flowers are pink.
Co-dominance is when neither allele is dominant and both alleles are expressed equally. An example is in human blood types. A and B alleles are both dominant to the O allele, but co-dominant to each other. Therefore, if an individual who is AO has children with an individual who is BO:
A O
B AB BO
O AO OO
The individual would either be blood type O (OO), blood type A (AO), blood type B (BO) or blood type AB (AB)
Explain why your results of the optimal temperature of the lactase enzyme make sense for the human enzyme
Answer:
Because the human body is below 40degrees Celsius which is the optimal temperature of the lactace enzyme.
At the optimal or average body temperature of the body the human body, the nature of the lactase protein is not denatured.
Explanation: Lactase enzyme is produced in the cells of the small intestine of humans and most mammals,the main function of the Lactase enzyme is to ensure the digestion of sugars that are present in the milk and other dairy products consumed by both humans and other mammals.
The optimal temperature of the lactase enzyme is 40degrees Celsius which means it can successfully fulfill and perform its functions within the human body whose temperature is generally below 40degrees Celsius.

4. Affinity chromatography can often be used to purify one specific antibody from animal blood serum in a single step, even though serum typically contains around 10 billion different antibodies and also includes many other types of proteins. Explain why this is true. If necessary, do some online research about antibodies first. g
Answer:
Affinity chromatography is a technique based on specific binding interactions
Explanation:
Affinity chromatography is a technique used to separate and identify macromolecules by their specific binding biological interactions. This technique enables the identification of macromolecules that establish specific types of binding interactions including, among others, antigens and antibodies, receptors and ligands, etc. Affinity chromatography is the most widely used technique for antibody purification because this method has high selectivity and enables to concentrate the target molecule in a single step. Antibody fragments such as single-chain variable fragments (scFV) can be purified by affinity chromatography when they are covalently immobilized to a solid support (for example, agarose beads).

describe the chromosomal difference between sex cells and a zygote (fertilized egg)/ body cells
Answer:
The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.
Explanation:
Ploidy is based on the number of chromosomes found in a cell:
If the cell contains the full charge of chromosomes it is called a diploid (2n). This occurs in body cells and in the zygote. When a cell contains half the charge of chromosomes, it is called haploid (n), and it only occurs in gametes or sex cells.The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.
