When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? Permease allows lactose to enter the cell when lactose enters the cell. The repressor binds to the operator in the absence of lactose. The repressor cannot bind to the operator in the presence of lactose. RNA polymerase transcribes the lac operon to make a single RNA molecule. CAP binds to cAMP and then to the promoter only in the presence of low glucose.

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase

b. Adaptation
c. Biodiversity
d. Homeostasis​

Answers

Answer:

B adaption

Explanation:

The scenario in which the Pandas evolve longer wrists to better eat bamboo over a long period will increase the possibility of artificial selection. The correct option is A.

What is artificial selection?

Artificial selection, also renowned as "selective breeding," is the practice of selecting for positive traits in agricultural products or animals rather than allowing the species to change and evolve naturally, as in natural selection.

The process by which organisms can choose individual lifeforms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve.

Adaptation entails dealing with both the physiological abiotic environment such as light, dark, temperature, etc. but in addition to the intricate biotic environment.

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase their possibility of survival. This is an example of artificial selection.

Thus, the correct option is A.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube

Answers

Answer:

Diffusion and active transport.

Explanation:

Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

Are Parakeets good starter pets? why or why not

Answers

Answer:

NO! They require a ton of attention, a large cage, and experience with birds. Parakeets are often marked as starter pets, but no, they are not.

First, they need a 3 feet long cage with 5+ toys that need to be changed each month. And they need natural perches, not the cheap wooden dowels, they will get feet problems. Most people don't do this, having a bored pet.

Second, parakeets will chew anything given/available to them, and a lot of things can be toxic to them, which can lead to the death of your pet.

Third, parakeets are messy and noisy. They poop a LOT and love to toss seeds around their cage. They also need millet and a calcium chew, which are also messy.

They also will want a friend, they are flock animals in the wild so 3-4 birds is a good number, but getting more birds means getting a large cage. The pet store will tell you it's fine, but it is not. ALWAYS SEEK HELP FROM A BIRD BREEDER.

Lastly, they need a bird proofed room to fly around in. No matter how large your cage is, they still need some out-of cage time.

Try a dove or pigeon instead, they are listen the #1 easiest and cheapest to care for pet bird.

when is the best time to harvest crops?why?​

Answers

[tex] \huge \bold \blue{★Question★}[/tex]

When is the best time to harvest crops? why?

[tex] \huge \bold \blue{★Answer★}[/tex]

Correct timing of harvest is crucial to crop loss prevention. Grain losses may occur caused by rats, birds, lodging, insects, and shattering. Timely harvesting ensures good grain quality and high market value.

Harvesting too early will result in a higher percentage of unfilled or immature grains, which will lower the yield and cause higher grain breakage during milling. Harvesting too late will lead to excessive losses and increased breakage in rice. Harvest time also affects the germination potential of rice seed.

[tex] \huge \mathsf \orange{MORE \: ABOUT :)}[/tex]

There are different ways to determine the correct harvest time:

Moisture content

Grain moisture content ideally is between 20−25% (wet basis). Grains should be firm but not brittle when squeezed between the teeth.

Ripe grains per panicle

The crop should be cut when 80−85% of the grains are straw (i.e., yellow-colored).

Number of days after sowing

Generally, the ideal harvest time lies between 130 and 136 days after sowing for late, 113 and 125 for medium, and 110 days for early-maturing varieties.

Number of days after heading

For dry season harvesting, an optimum time is 28 to 35 days after heading. In wet season harvest, optimum time is 32 to 38 days after heading.

Other considerations

Harvesting also needs to be timed so that threshing can be done as soon as possible after cutting to avoid rewetting and to reduce grain breakage.

If the crop has a lot of surface moisture, (e.g. from previous rainfall or early in the morning), it is advisable to wait until the surface moisture dries off.

Why is a sea otter a “keystone”??

Answers

Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp.

This is because eliminating them would cause a trophies cascade. The sea otter’s prey would increase, and the prey of that prey would decrease. Thus, otters are a “keystone” species.

The human body needs minerals to survive. Without
minerals, the body could not function properly. The minerals
that make up rocks are the same minerals that someone
might eat in a bowl of cereal! The body needs about 80
different types of minerals to function properly. Iron enriches
the blood, salt maintains fluid balance, calcium fortifies the
bones, and fluorine strengthens the teeth. Most vital
minerals can be absorbed into the body from eating plants
and lean meats. However, many food manufacturers add
minerals to their products to make them more desirable to
consumers. Eating a balanced diet can ensure that the
proper amount of these essential minerals is ingested.

Question:

The passage tells us that "many food manufacturers add minerals to their products to make them more desirable to consumers." Do you think that this is a good idea? What are the pros and cons?

Answers

Answer:

You have to put down what you think and not what other people thing

Explanation:

You can simply answer this question yourself by doing research or just thinking if its a good idea

Eating vegetables and lean meats can help the body absorb the majority of essential nutrients. However, many food producers add minerals to their products to increase customer appeal.

What are nutrients?

Chemical elements known as nutrients are present in all living things on Earth. They are essential to the survival of all living things, including humans, animals, and plants.

The breakdown of food by nutrients provides energy for living things. They are utilised in every bodily function of an organism.

The majority of vital nutrients can be more easily absorbed by the body when veggies and lean meats are consumed.

To boost consumer appeal, several food companies do, however, add minerals to their products.

Although processing has many advantages, it can also be harmful and reduce the nutritional value of food.

For instance, blanching causes vitamin and mineral leaching losses. Additionally, during processing, milling and extrusion might result in the physical removal of minerals.

Thus, these are some pros and cons of the given scenario.
