Answer:

The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.

Explanation:

The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.

In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed  due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.

Answer:

In other words, physical or chemical parts of the environment that affect the organisms that are in that environment.

Explanation:

For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth. Light level is an important factor in aquatic ecosystems. hope this helps you :) god loves you :)

Light level is an important factor in aquatic ecosystems.

The physical or chemical parts of the environment that affect the organisms that are in that environment.

An aquatic ecosystem is a water-based environment. Abiotic factors are the non-living components that form the environment in which organisms subsist in a current.

The main abiotic factors in the marine environment are as; light, temperature, salinity, and hydrostatic pressure. dissolved oxygen, acidity (pH), salinity and depth.

Here Without pollution or acid rain, most lakes and streams would have a pH level of around 6.5.

Therefore Light level is an important factor in aquatic ecosystems.

Explanation:

Answer:

an alkali also can be defined as a base that dissolves in water. a solution of soluble base has a pH greater than 7.0. the adjective alkaline is commonly, an alkalescent less often, used in English as a synonym for basic, especially for bases soluble in water.

Explanation:

hi !!

here i think all areirrational expect root 36/1296,

1. root 2= root 2= 1.414213562

2. 2/root 6= root 6 /3 = 0.8164965809

3. root 36/1296=1/6=1.66666667

4. - root 6+6= -2 root 3 = -3.464101615

so, they are extended and dont have exact value so all are irrational expect no. 3 because it can be expressed in 1/6 fraction form but others will come on root form.

Hope it helps...

Explanation:

Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia,

Y = Y chromosome

Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:

Xx- X and x gametes

XY- X and Y gametes

Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.

XX (1) - unaffected normal female

Xx (1) - unaffected carrier female

XY (1) - unaffected normal male

xY (1) - affected male

Based on the questions;

- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2

- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

Explanation:

biodegradable waste can be found in municipal soild waste or sometimes called biodegradable municipal waste ,or as green waste ,food waste,paper waste and biodegradable plastic.other biodegradable waste include human waste ,manure,sewage,sewage sludge and slaughterhouse waste .

you can send it for recycling into compost.

you can treat biodegradable waste on an industrial scale by either composting or anaerobic digestion.

composting is more suitable for fibrous materials.

anaerobic digestion is more suitable for wastes and sludgest that degrade easily.

#produce; 

#grow;

#Respond to stimuli/ irritability;

The characteristics of living that a motor vehicle lacks include the ability to feed, respond to stimuli, grow, reproduce, and die.

Living organisms carry out nutrition, unlike motor vehicles.

Living organisms are able to respond to external stimuli but motor vehicles cannot.

Living organisms are able to grow/increase in size, motor vehicles have fixed sizes.

Living organisms have the capacity to reproduce for continuity, motor vehicles lack this ability.

After some time, living organisms die, motor vehicles do not die naturally.

Answer:Organisms decompose more quickly when they are in contact with oxygen. Most environments exposed to the open air are in contact with plenty of oxygen, so the soft tissues of dead organisms, whether plants or animals, decay quickly. ... For an organism to become a fossil, it must not decompose or be eaten.

Explanation:

Answer:

The author thought this because e-skin might hold promise for use in soft, wearable hearing aids. Unlike conventional aids, soft devices are more comfortable because they mold to human skin. When the ear receives sound vibrations, there are hair cells in the cochlea that vibrate and translate the sounds into electrical signals. These electrical signals are transmitted to the auditory nerve, which transmits the information to the brain.

Answer:

Sound is one of the five major senses. The nervous system carries sound signals from sensory receptors to the brain. E-skin has many sensory receptors that can carry signals toward the brain, enabling us to react to sounds. Because e-skin is soft, scientists can use it to make effective hearing aids that are quite comfortable to wear.

Answer:

6 months

Explanation:

First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.

Answer:

"NAD has more chemical energy than NADH" is the FALSE statement.

Explanation:

It is totally true that NAD can be recycled many times, it can actually receive electrons for use in chemiosmosis and is reduced by the action of enzymed. During both glycolysis and the Krebs cycle. All these statements are true. But when it comes to NAD and NADH, it is false that NAD has more chemical energy than NADH. There is actually more energy in one NADH, that can lose electrons to transfer energy.

The correct answer is -  Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

Explanation:

The Hawaiian Islands are the chain of eight major islands situated in U.S. of Hawaii. These are formed over a hot spot. About 75 million years ago such hotspot took place in the center of the Pacific Plate.

There are hot spot due to the volconic activity and in the moving over the tectonic plate of a subduction zone. Volcanic activity and overriding of plates that cause rising magma by melting the moving down plates whice leads to volcanic arcs formation. The magma that rose gradually cooled down and become solid over the time. It is an example of a large seamount and island chain created by hot-spot volcanism.

Thus, The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

Answer:

Negative feedback

Explanation:

Negative feedback is produced when a mechanism is amplified through an inverse loop, which tends to reduce the fluctuations in the system. In this case, the negative feedback mechanism represents a homeostatic response of the body where the release of a target hormone (hormone C) decreases in response to the increase of a protein (protein Q) upstream in the signaling pathway. Therefore, in this scenario, it is expected that negative feedback causes a decrease in hormone function.

It is true that Mendel always got close to a 9:3:3:1 ratio for phenotypes in the F2 generation of any dihybrid cross. This validates his law of independent assortment of genes.

The 9:3:3:1 is usually gotten from any dihybrid cross of F2 generation. The results given are always 9 offsprings containing dominant traits, 3 offsprings each which possess a dominant and recessive trait and 1 offspring with a recessive trait.
