Answer:
Like the lac operon, the trp operon is a negative control mechanism. The lac operon responds to an inducer that causes the repressor to dissociate from the operator, derepressing the operon. The trp operon responds to a repressor protein that binds to two molecules of tryptophan.
What is the carbon cycle
Answer:
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.

Which is a common practice for farmers to yield higher crop production?
A) Overplowing mixes the nutrients in the soil
B) consistently plant the same crop every year
C) allow later-successional growth to replace nutrients
D) keep the area planted with early-successional species
NOT C
Answer: D) keep the area planted with early-successional species.
Explanation: Early successional species grow fast and spread their seeds rapidly and widely. This could help to bring in a potentially high crop yield.
It likely is not A because overplowing leaves the soil susceptible to erosion and damages the physical infrastructure.
B should not be the answer because consistently planting the same crop year-round can deplete the nutrient resource said crop relies on. It’s why crop-rotating is a thing now.

If a rose plant has a genotype of Ffgg, what are the possible genetic combinations of offsprings that could be
present from this plant?
Answer:
Suppose you have a parent plant with purple flowers and a parent plant with white flowers. Because the b allele is recessive, you know that the white-flowered parent must have the genotype bb. The purple-flowered parent, on the other hand, could have either the BB or the Bb genotype. The Punnett square in Figure below shows this cross.

How do the three types of RNA work together to create proteins
using the genetic information contained within DNA?
Answer:
The three roles of RNA in protein synthesis. Messenger RNA (mRNA) is translated into protein by the joint action of transfer RNA (tRNA) and the ribosome, which is composed of numerous proteins and two major ribosomal RNA (rRNA) molecules. ... Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes.2. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Explanation:
The first one is for How do the three types of RNA work together to create proteins

The structure of a human skin cell differs from that of a human muscle cell. The two cells most likely have different __________. Choose the correct answer.
Answer:
The correct answer would be - functions.
Explanation:
The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.
In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
Ralph and Cory are friends on their way to a big party. Cory is familiar with the party's hosts and seems to always know what to say to be the life of the party. Ralph, who has never engaged with this group, is unsure of how to act or participate. What can be said of Ralph and Cory?
Answer:
Ralph is more stressed by the situation because Cory has a better set of social skills than Ralph.
Explanation:
Social skills are attributes that make interactions with others easy and comfortable for people. The scenario shows that Cory is more lively and sociable, thus, his social skills are better than Ralph's. Ralph on the other hand is apprehensive because he is not very sociable and finds it difficult to manage his interactions with people.
Ralph's situation is worsened by the fact that he is unfamiliar with the people in the party.

Just took it xd <3
The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.
What is photon?
The energy stored in bundles or the packets has been known as the photon. Chemosynthesis has been referred to the process by which some organism obtain food from inorganic chemicals rather than from light. There are many chemosynthetic bacteria that obtain food by the metabolism of methane, hydrogen sulfide or carbon dioxide.
Light photons are not required for chemosynthesis. It is only necessary during photosynthesis. Chemosythesis has been involves the inorganic chemicals therefore, light photons are not required during chemosynthesis.
The organism which provides evidence that matter and energy can be cycled through an ecosystem without sunlight is a lanternfish on the Atlantic Ocean floor and the technique which will prove most effective to eliminate the greatest number of organisms is to remove methane and hydrogen sulfide.
Therefore, The compound can provide the energy for chemosynthesis is light photon and carbon dioxide. Thus, option C is correct.

Heredity is the passing on of traits from parent to offspring. Heritable information is important for life to continue. What is the role of meiosis in heredity?
Write your answer in the space below.
Answer:
Meiosis helps create more diversity and individuality in the genes of organisms.
Explanation:
Hope this is helpful, this is what I learned last year.
Answer:Sexual reproduction allows for the passing of traits from parent to offspring. In sexual reproduction, meiosis produces gametes that have chromosomes from the parents. The chromosomes carry genetic information. When the gametes fuse during fertilization, an individual with a unique combination of chromosomes or a unique genetic make up is formed.
Explanation:this is the sample response on edge
is teeth and curly hair a recessive trait or dominate trait plz explain
Answer:
Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there's a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.

What causes clouds of dust and gas to form a protostar?
Answer:
Mainly the gravitational instability in the clouds of dust (molecular clouds)
Explanation: Stars are born within molecular clouds, which are mostly made of hydrogen and lesser amounts of helium and other heavier elements. The formation of a protostar begins when gravitational instability is present in the molecular cloud, caused by regions of higher density. Eventually, the clouds of dust start to collapse to due gravity, the protostar forms. The protostar, is still an underdeveloped star, meaning it does not perform nuclear fusion in its core, but it still produces its own heat from the extreme pressure.
