Answer 1

When completing Punnett Squares, you cross the letters that meet up. For example, their are two TTs and two Tts. Dominant will always show before a recessive so if it's TT or Tt it will be the dominant version. two tt's mean that it's recessive. In a Punnett Square, one box = 25%.

Part A: The genotypic ratio is 50% TT and 50% Tt. The phenotypic ratio is 100% tall.

Part B: The two Tt's could produce a short plant because there is a 25% that the parents will both give t's.

In an inducible operon, the inducer is often the __________ in the pathway being regulated; the inducer binds to the __________, thus rendering it __________.

Answers

substrate; repressor; inactive

In the absence of the inducible operon, the repressor operon will be bind to the gene and prevent its transcription. When the substrate present, which is inducible operon, it will bind to the repressor so the gene can be transcripted. This mechanism can be seen in lac operon of the lactose.

Final answer:

In an inducible operon, the inducer, often the substrate, binds to the repressor which renders it inactive. This allows the system to 'switch on' genes only when necessary.

Explanation:

In an inducible operon, the inducer is often the substrate in the pathway being regulated. The inducer binds to the repressor, hence rendering it inactive. An inducible operon is part of a gene regulation system, often found in prokaryotic cells, where the presence of a certain substance (the inducer) frees up the process of transcription by neutralizing the repressor protein that blocks it. This system allows the organism to conserve resources by 'switching on' genes only when the appropriate substrate is present and available for processing.

Which direction do a comet's dust and plasma tails point?

Answers

Dust and particulate trails point in the direction opposite of the star closest to it. The outgoing solar energy and radiation slowly shaves off matter of the object, and thus creates a tail behind the object. Simply put, the tail is on the dark side of the object.

Final answer:

Comet tails, both dust and plasma, point away from the Sun due to the Sun's radiation and solar wind. The dust tail is formed by light reflecting off evaporated particles, while the ion (gas) tail is formed by the Sun's solar wind interacting with ionized gases.

Explanation:

A comet's dust and plasma tails always point away from the Sun. This phenomenon is due to the interaction between the Sun's radiation and the comet materials. As the comet approaches the Sun, the heat causes gases and dust to evaporate from the body of the comet. This forms the comet's tail, which is an extension of its atmosphere.

The comet essentially has two tails: the dust tail and the ion tail. The dust tail is made up of tiny dust particles, pushed away from the Sun by light reflecting from them, creating a tail that curves a bit. On the other hand, ion tail is made of ionized gas and is affected more by the Sun's solar wind, which are streams of charged particles issuing from the Sun. This creates a tail that points more directly away from the Sun.

B) for later harvest

D) lack of room in the harvest basket

Answers

The correct option is c, to grow new plants.

People in the Cahuilla tribe depended mostly on desert plants for their food. Acorns were popular as the oak trees could not grow in desert areas. The common food for these tribes included the fruit of mesquite tree. During the spring season mesquite blossomed which was eaten by boiling. During summers the pods which were green was used as a drink by grinding. After the pods dried they were eaten from the tree directly or made mesquite cakes which could be stored for long time. In all the conditions and seasons, not all the beans were harvested but a portion was left in the plant so as to let them grow into new plants and trees.
