The lac operon is regulated by both the availability of lactose and glucose. How does E. coli regulate transcription of the lac operon?
Answer:
E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).
Explanation:
The lac operon is regulated by both the availability of lactose and glucose. E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).
This cAMP acts a signaling agent which is made by E. coli anytime glucose levels are low In the cells which helps regulate the transcription process as glucose is needed for it .

I NEED THIS ANSWER Transcribe and Translate this DNA sequence:
TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC
Answer:
Given the sequence of DNA bases sequence:
DNA TAC GAG TTG CCG TAT ATT GCG CTC GAC TGCTranscription into mRNA and translation would be:
mRNA AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Amino acids Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-ThrExplanation:
Genetic information is found in DNA, and this information depends on a sequence of bases —adenine, thymine, cytosine and guanine— in the DNA molecule.
Transcription consists of creating a strand of mRNA, from the sequence of bases in a DNA strand, which it assumes:
The sequence of RNA is complementary to the DNA sequence that forms it, following the complementarity of bases. In RNA there is no base thymine, which is replaced by uracil.The sequence of mRNA is organized into triplets or codons, each of which encodes for the synthesis of an amino acid (translation), indicating both the start of a polypeptide chain and the stop of protein synthesis. Knowing this information, it can be stated that, following a sequence of DNA bases, the resulting transcription and translation would be:
DNA TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC Transcription AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Translation Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-ThrResulting amino acids and indications in protein synthesis Methionine (inicio), Leucine, Asparagine, Glycine, Isoleucine —Stop— Arginine, Glutamine, Leucine and Tyrosine.

When a mitochondrial chaperone helps a mitochondrial matrix protein into the matrix by biased diffusion, the chaperone is said to be acting as ______.
a. Brownian motion
b. biased diffuser
c. Brownian ratchet
d. misratchet
e. unbiased diffuser
Answer:
c. Brownian ratchet
Explanation:
Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.
The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.
The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.

why are colonial organisms not truly multicellular?
Answer:
Colonial Organisms
The difference between a multicellular organism and a colonial organism is that the individual organisms that form a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot. This enables the colony to swim towards the light.
Explanation:
All based on research.
Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?
What happens in each stage?
GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)
KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)
ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)
How many ATP molecules made during each stage?
GLYCOLYSIS: 2 ATP
KREB'S CYCLE: 2 ATP
ELECTRON TRANSPORT: 34 ATP
Khan academy is the best for breaking down processes in chemistry! I used khan all the time when I had trouble understanding chemistry last year.

8 facts about the Geosphere
Facts:
The Geosphere is basically the insides of the earth so breaking it up into eight parts will be based on each section of it.
1. The crust is the top layer of the Earth, it consists of the water and land we see. It is a shell that lays atop or covers the Upper mantle piece.
2. The mantle is a layer between the crust and core, Earth's mantle is a rocky shell that is roughly 2,900km thick and is 84% of Earth's volume.
3. The Geosphere is the solid part of the Earth that consists of rock, soils and sediments on the surface of the Earth.
4. The core is the innermost layer of the Earth and is up to 6371km from the surface of the Earth, it consists of Nickel and Iron and are seen as main components of it.
5. The outside of the core is known as the molten core due to it mainly being liquid metal from the heat and the inner portion of the core known as the solid core.
6. Another name or term given to the Geosphere is called the lithosphere, depending on the definition they both mean the same thing but are still argued by scientists.
7. The Geosphere is in constant motion due to the tectonic plates. These plates are what causes earthquakes ,volcanoes to erupt and even tsunamis.
8.There are eight major tectonic plates making up the earth's geosphere. They are constantly moving, but usually only a few centimeters each year, this is known as continental drift.

When crude oil is distilled, it is separated into categories. What are those categories characterized by?
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
Crude oil is made up of different fractions of hydrocarbons. As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. Components with short carbon lengths rises out from the column first and are cooled and extracted. The categories are thereby, classified based on differences in their boiling points.What is the technology and practice of growing and maintaining cells in a laboratory known as?

Describe the osmotic regulation strategies of marine fish
Answer:Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water. A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills.

An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the offspring
Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.
In general, the land changes temperature much more rapidly than the
ocean. How does this fact explain the existence of land breezes and sea breezes?
Answer:
Answer
Explanation:
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean.
