The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat.  All computers need a fan to prevent them over-heating for this very reason.  Therefore heat is lost and energy is wasted.

Another example is a lightbulb.  When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.

These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)

Which statement about organism classified in the same genus is true?
notsponge [240]

Genus represents taxonomic rank above species and below family. When organisms belong to the same genus, they must be of the same phyla, but may be in different species. In binomial nomenclature it is the generic name shared by the group of close relative.

Which statements describe the inheritance of traits? Select three options.
liraira [26]

Answer:

<u><em>The correct options are:</em></u>

<u><em>All traits are inherited.</em></u>

<u><em>Offspring inherit one allele for a gene from each parent.</em></u>

<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>

Explanation:

  • In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.

  • Traits are inherited from parents, however they can be influenced by the environment.

  • The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.

  • When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.

11. Why<br> are<br> organisms with more similar amino acid sequences more closely related?
jok3333 [9.3K]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
