6 0

The statement that is true is active transport moves against the concentration gradient.

<h3>WHAT IS ACTIVE TRANSPORT</h3>

Active transport is one of the two types of cellular transport that involves the movement of molecules against a concentration gradient.

This moves that movement occurs from a region of lower concentration to a region of higher concentration. Since movement is against a concentration gradient, it involves input of energy (ATP).

Therefore, the statement that is true is active transport moves against the concentration gradient.

Which pair of terms most accurately describes life history traits for a stable population of wolves? A. semelparous; r -selected
Lera25 [3.4K]

The correct option is (D) iteroparous; K -selected

Iteroparous organisms are the organisms that reproduce multiple times.

<h3>What is Semelparity and Iteroparity?</h3>
  • Semelparity and iteroparity are the two different reproductive strategies available to living beings.
  • Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
  • Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
  • There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

What is the main difference between renewable and nonrenewable resources
Julli [10]
<span>The main difference of renewable and non-renewable resources lies in the capacity of the environment to replenish itself. Renewable resources are resources that can be easily replenished by the environment over a short period of time, while non-renewable resources take more time. <span>

Examples of renewable resources are solar energy, harnessing the sun's power that shines day to day. Wind energy that exists naturally is also a renewable source. Geothermal energy, heat coming from the center of the Earth, and Biofuels, fuels made from living organisms, are all renewable energy. 

<span>Non-renewable energy resources are the fuels we use in our cars, minerals from the soil, coal, among others are supplies that also come from Earth. These are all materials that might take a long time (probably millions of years) to be fully restored. </span>

explain how a change in the sequence of nucleotide in a strand of DNA might cause a protein to malfunction
Diano4ka-milaya [45]

Answer: Proteins are made using DNA as a template. The DNA is turned into RNA, and the RNA is then turned into DNA. 

A change in these nucleotides could end up making some part of the protein different. A single nucleotide change could be silent (no change in the protein) or could change a single amino acid (amino acids are the building blocks of proteins). If that was an important amino acid, the protein might not function at all! A silent change can occur because the same set of nucleotides sometimes makes the same final amino acid (for example, reading "gcc" "gca" "gcg" or "gct" nucleotides all mean "alanine" amino acid). 

The deletion of a single nucleotide, or the addition of one, can change the entire sequence of amino acids that come after it! Nucleotides are read in sets of three, so this throws off how the DNA is read. If would be like turning "The brown fox jumps over the dog" into "The gbrow nfo xjump sove rth edo g". Completely different! All of the words are thrown off.

I know it is long but I hope it helped

:D
