A penny is at rest is experiencing inertia because it is not moving.

<h3>What is inertia?</h3>

According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.

Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.

Thus, a penny is at rest is experiencing inertia because it is not moving.

He reflexes from sense organs in the head are co-ordinated by the brain.

oee [108]

Answer:

sense of touch

Explanation:

There are five sense organs that involved vision, hearing, taste, smelling, and touch.

Sense of touch is involved in a reflex coordinated by the spinal cord as when we touch something, sensory nerves sends the information to the brain and spinal cord. the motor nerves process the signals in the brain and send it back to the muscles, that leads to contraction reflexively.

Hence, the correct answer is "sense of touch".

El guepardo puede alcanzar velocidades hasta de 110 km/h, para obtener esta información la biología se apoyó en la…

brilliants [131]

Answer:

la tecnología del Sistema de Posicionamiento Global (GPS)

Explanation:

Los guepardos son animales capaces de acelerar rápidamente, llegando a alcanzar una velocidad de 29 metros por segundo (aproximadamente 110 km/h). Los biólogos de vida silvestre determinaron la velocidad de los guepardos mediante la utilización de collares con GPS. Para la colocación de estos collares, los guepardos tuvieron que ser parcialmente sedados mediante la utilización de dardos tranquilizantes. La tecnología del GPS permitió la localización y de este modo la determinación de la extraordinaria aceleración que alcanzan los guepardos; sin embargo, esto es sólo un aspecto de su estrategia para cazar, ya que a partir de esta tecnología fue también observado que estos animales son capaces de girar y detenerse repentinamente al atrapar una presa.

Why did the U.S. become involved in Afghanistan?

Liono4ka [1.6K]

The narrative and goals for what has become America’s longest war have shifted in the past 16 years, and they may take a new turn Monday night, as President Donald Trump is expected to announce his policy approach for Afghanistan.The war started in October 2001 in the wake of the September 11th attacks, under then-President George W. Bush, and after Obama, Trump is now the second president to inherit -- and have to make a decision on how to handle -- the ongoing conflict.

When Bush first announced the military action on Oct. 7, 2001, he described “strikes against al Qaeda terrorist training camps and military installations of the Taliban regime in Afghanistan.”

Na+ pumps function is to:

nalin [4]

Answer: Option B

Explanation:

The sodium pump is used to control the osmolarity of the cell by pumping the sodium ions out of the cells that have diffused inside the cells due to their high electrochemical gradient.

This pump plays an important role in the neurons and helps in initiating the action potentials.

This pump helps in the signals transduction from brain to various parts of the body.

Hence the correct answer is that this" Pump Na+ out of the cell".

Why is it important to have MET at the beginning of mRNA?

astra-53 [7]

The Beginning of mRNA Is Not Translated
Interestingly, not all regions of an mRNA molecule correspond to particular amino acids. In particular, there is an area near the 5' end of the molecule that is known as the untranslated region (UTR) or leader sequence. This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein (Figure 3).

So, what is the purpose of the UTR? It turns out that the leader sequence is important because it contains a ribosome-binding site. In bacteria, this site is known as the Shine-Dalgarno box (AGGAGG), after scientists John Shine and Lynn Dalgarno, who first characterized it. A similar site in vertebrates was characterized by Marilyn Kozak and is thus known as the Kozak box. In bacterial mRNA, the 5' UTR is normally short; in human mRNA, the median length of the 5' UTR is about 170 nucleotides. If the leader is long, it may contain regulatory sequences, including binding sites for proteins, that can affect the stability of the mRNA or the efficiency of its translation.
