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 ...

In skeletal muscle Catt is essential for the contraction process. For skeletal

zaharov [31]

Answer:

The source of Calcium (Ca⁺⁺) for the skeletal muscle cells is the sarcoplasmic reticulum, the main store of intracellular Ca⁺⁺.

Explanation:

Calcium (Ca⁺⁺) is an ion that plays an important role in muscle contraction, a process that requires high cytoplasmic concentrations of this ion to promote myofibrillary activity.

The sarcoplasmic reticulum (SR) -equivalent to the endoplasmic smooth reticulum- is an organelle that regulates the contractile activity of skeletal muscle. The two terminal cisterns of the SR attach to the T-tube, forming a triad, which surrounds the myofibrilla.

Once the muscle cell receives the signal to contract, the Ca⁺⁺ channels are opened and allow Ca⁺⁺ to enter the cell, promoting the exit of this cation from the SR and increased its cytoplasmic levels. This stimulates muscle contraction.

Describe what hormones are and what they do

Wittaler [7]

Hey hope this helps. So starting off with a few things that cause hormones.

The Endocrine System , So The best way to answer the question "what are hormones?"  is to take a look at some of the major hormonal systems in the body. Hormones are created by glands, which are part of the endocrine system. The main hormone-producing glands I've listed below

Hypothalamus: The hypothalamus is responsible for body temperature, hunger, moods and the release of hormones from other glands; and also controls thirst, sleep and sex drive.

Parathyroid: This gland controls the amount of calcium in the body.

Thymus: This gland plays a role in the function of the adaptive immune system and the maturity of the thymus, and produces T-cells.

Pancreas: This gland produces the insulin that helps control blood sugar levels.

Thyroid: The thyroid produces hormones associated with calorie burning and heart rate.

Adrenal: Adrenal glands produce the hormones that control sex drive and cortisol, the stress hormone.

Pituitary: Considered the "master control gland," the pituitary gland controls other glands and makes the hormones that trigger growth.

Pineal: Also called the thalamus, this gland produces serotonin derivatives of melatonin, which affects sleep.

Ovaries: Only in women, the ovaries secrete estrogen, testosterone and progesterone, the female sex hormones.

Oh and by the way the person below me copied and pasted her answer here's proof. I posted a screenshot of her answer.

Just saying.

klasskru [66]

Answer:

John accidentally put his hand on a burning stove and immediately drew it back, yet still he is experiencing pain.

In this sentence, stimulus will be a hand touching fire of the stove. External response will be moving of the hand from the stove immediately.

A stimulus can be described as any physical or chemical change which elicits a response form a living organism. The stimulus is detected as a signal and response is generated in accordance to the signal.
