Explanation:

Sensory receptor interact with stimuli, such as light sound temperature and pain which is transformed into the code that is carried to the brain by the chain of neurons. Once the signal reaches the end of an axon, which is at the end of neuron, a neurotransmitter is released and the process repeats.

The information is sent in the form of nerve impulses and reaches the spinal cord through the sensory neurons of the PNS.

Answer:

What are the Krebs Cycle products? Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.

Explanation:

For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles. These products can be multiplied by two to produce the per-glucose yield. Though only one ATP (or GTP) is produced directly per cycle, the products NADH and FADH2, can produce ATP (or GTP) in a further process of cellular respiration called oxidative phosphorylation. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. The Krebs cycle is found in all cells that use oxygen. Combined with the process of oxidative phosphorylation, the Krebs cycle produces the majority of energy used by aerobic cells with the percentage energy provided for humans being greater than 95%.

Answer:i think is C

Explanation:

Explanation:

The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)

Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.

Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.

Within the mitochondrial matrix of mitochondria, the Krebs cycle occurs. In the cytoplasm of the cell, glycolysis happens, hence option C is correct.

The Krebs cycle processes occur in the mitochondrial matrix, a dense solution that surrounds the mitochondrial crests in eukaryotes. In addition to water, the matrix also includes all the enzymes, coenzymes, and phosphates required for the cycle's biochemical reactions.

While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration respectively occurs in the cytoplasm and mitochondria of the cell.

The cycle occurs in the mitochondrial matrix and results in the production of chemical energy in the forms of ATP, FADH2, and NADH.

Therefore, in the mitochondrial matrix of mitochondria, the Krebs cycle occurs, hence option C is correct.

Answer:

The success of staghorns is partly due to their lightweight skeletons, which often grow quickly enough to outcompete other corals for sunlight, a resource demanded by their photosynthesizing algae. Some staghorn species can grow 4 to 8 inches (10 to 20 centimeters) per year — a blistering speed by coral standards.

Answer:When a plant is eaten by a primary consumer, only 10% of the energy is passed on. ... Decomposers break complex materials into simple components after producers and consumers die, using up the energy they contain. In this way, minerals and elements needed by plants are released in a form that can be absorbed by them.

A. Skin color, a polygenetic trait, is also determined by environmental factors.

Explanation:

When you are a lifegaurd you are outside much more which means you are very likely to get a tan; Therefore changing the pigment of Pat's skin.

I hope this helps you :) Have a nice day!

The study of genes and inheritance is called genetics. In a gene pair, one allele is dominant and the other is recessive.

The correct answer is the variation in gene combination.

According to the question, pigmentation is different due to the combination of the different genes. These genes produced melatonin which decides the skin tone, The dominant genes code for a darker tone, and the recessive gene code for a lighter tone.

Hence,  the correct answer is mentioned above.

Metallic Bonding is restricted to metals only. In the metallic bonding, There is a electrostatic force of atrraction between the metal ions (which are positive)

and the electrons(which are negative).

The metal ions are arranged in a lattice pattern which is the regular repetitive structure.

Every metal atom donate one or two valence electrons, so due to the BULK presence of the electrons, It results in a formation of sea of electrons. So the valence electrons don't just stay on their own atom, they roam around the whole metal. They are just like a sea of electrons. This is why it is called the electron sea model. basically metal ions are present as a iceberg or island in the freely floating sea of electrons.

The sea of electron works as a electron GLUE, That means the metal ions are strongly ATTRACTED to the electron, so When apply pressure on the metals they DONT BREAK that means they are not brittle but malleable and ductile. This is because of the moving electrons and because the cations slide easily past each other, The ability of the atoms to roll over each other into new positions without breaking the metallic bond is because of the electron glue.

Brittle; Hard but breakable due to absence of sea of electron.

Malleable and Ductile; Transformed into sheets and thin wires so they are somewhat ELASTIC.

Answer:

Dominant

Explanation:

A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).

A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).

I think the answer is landslide

Landslide is the massive movement of material from high altitude to low altitude, producing slope breaks. The correct option is B. The type of mass movement described in the example is landslide.

A landslide can be defined as a massive movement of materials that include rocks, soil, plants, debris, and other elements composing the ground.

Mass of material moves from high altitude to low altitude due to the action of gravity and the influence of other factors as humidity excess.

These movements occur because the material is exposed to external forces (gravity) that supersede the strength of these materials producing slope breaks.

Other factors such as rains, increase in water level, snowmelt, erosion, earthquakes, human activities, and others influence the landslide occurrence.

The correct option is B. The type of mass movement described in the example is landslide.
