Answer:

The generated mRNA sequence will be AAACGAUAUGAUAUCAUG...

Explanation:

DNA consists of nucleotides, which are composed of nitrogenous bases that are called Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). These nitrogenous bases must pair with each other for the DNA molecule to be formed. In DNA, Adenine only pairs with Timine, while Guanine only pairs with Cytosine. In this case, we can say that the nitrogenous bases pair with other bases that are complementary to them.

The mRNA is formed from the DNA and the enzyme that produces the mRNA, uses the sequence of nitrogenous base pairs of DNA to produce the mRNA, however, the mRNA does not have the Thymine base, but the Uracil (U) base that pairs with Adenina. In this case, when the DNA contains the Adenine base, the mRNA produced will present the Uracil base. When the DNA has the Guanine base, the mRNA will have the cytosine base.

Thus, a DNA with the base sequence TTTgctatactatagtac will present an mRNA with the base sequence AAACGAUAUGAUAUCAUG ...

Im not really sure about the water, other than the trees wouldn't be absorbing it so there would be extra? But a huge amount of trees like that produce a lot of oxygen, so there would not be less oxygen in the environment. Hope this helps!

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex
OLEGan [10]

Answer: From the question,the correct order of how hearing works is listed below:

--> sound wave is generated from hitting a key on a piano,

--> Incus moves,

--> Stapes moves,

--> Sound wave enters inner ear,

--> Fluid in the cochlea moves,

--> Fluid wave moves across Organ of corti based on frequency,

--> Ions enter hair cells,

--> hair cells bend,

--> auditory nerve transmits the signal to the auditory cortex,

--> auditory cortex recognizes the sounds.

Explanation:

In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:

--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)

--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).

--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).

To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.

As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.

In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.

The color of beef is largely determined by myoglobin.
LuckyWell [14K]
The color of beef is determined by myoglobin because these cells are actually responsible for transporting oxygen-rich molecules to the the tissues of the animal. This characteristic gives it the color that it has and is very abundant in large organisms like cattles.
