Which scenario is an example of the transfer of thermal energy by
NARA [144]

Answer:

A

Explanation:

Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.

Answer:

Isotonic contractions maintain constant tension in the muscle as the muscle changes length. This can occur only when a muscle's maximal force of contraction exceeds the total load on the muscle. Isotonic muscle contractions can be either concentric (muscle shortens) or eccentric (muscle lengthens).

nataly862011 [7]
Plantae: Autotrophic, Multi- or Monocellular, have cell walls as well as a membrane, have a chloroplast making the characteristic green color and to capture sunlight for photosynthesis. Break down generated glucose into it's components.

Animalia: Heterotrophic, Multi- or Monocellular, have a cell membrane made of a phospholipid bilayer, and many mitochondria to aid with movement energy. Feed on plants or other animals. Eukaryotic cells.

Fungi: Heterotrophic, most Multicellular, have a rigid cell wall made of chitin, specialized cells to aid with decomposition of dead organic matter. Eukaryotic cells.

Protista: Can be plant-like, animal-like, or fungus-like. Most are single-celled, may be chemosynthetic or photosynthetic. Eukaryotic cells.

Archeabacteria: Prokaryotic. Do not have nuclei or membrane-bound organelles. Move around using a flagellum to propel itself. Lives in mainly fluid environments (air, water). Separated from Eubacteria due to it's high tolerance of extreme conditions, such as high salinity, no oxygen, burning heat, or freezing cold. Can be chemosynthetic or anaerobic, as well as aerobic.

Eubacteria: Normal, everyday bacteria. Prokaryotic, chemosynthetic, anaerobic, or aerobic. Do not have nuclei or membrane-bound organelles. Mobile using a flagellum to propel itself.

Two organisms, with the genotypes FFEe and FfEE, are mated. Assuming independent assortment of the F/f and E/e genes: 1) Provide
IgorC [24]

Answer:

<h2> FFEE, FfEE, FFEe, and FfEe</h2><h2> All the progeny show  same 1/4 or 25% probability.</h2>

Explanation:

Given; parents are with genotype FFFe and FfEE

F/f and E/e  are showing independent assortment,

1. Genotype of all possible offspring are;

gamete from parent FFEe are; FE and  Fe ,

gamete from parent FfEE are; FE and fE.

So  genotype of offspring are:   FFEE, FfEE, FFEe, and FfEe

2. All the progeny show  same 1/4 or 25% probability.

Please rewrite in own words. PLEASE HELP VERY DESPERATE!!!!!!!!!!!!!!!
butalik [34]
Fossils give  Scientists look into past life. A dinosaur that mixes together a reptile and a bird  helps scientists understand present day reptiles & birds. Animal Ancestry helps Scientists discover what ancestors of present day animals are. example: a dinosaur and an alligator.  DNA sequences help with this. By matching together the strands of DNA from these fossils can help scientists match together the strands of DNA sequences  For example the gene for a protein found in a horse will overlap in sequence fairly well with the protein gene from a cow but will not match very well with a worm.
