Explanation:

Answer:

It affects life on Earth by causing the heat rays of the sun weaker.

Explanation:

The ozone layer acts as a shield for life on Earth. The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth's surface and harming living organisms.

Answer:

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.

Answer:

S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth.

Explanation:

Answer:

They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves. ... Surface waves are the slowest moving of all waves, which means they arrive the last

Explanation:

The east coast of South America does not have mountains volcanoes and earthquakes because of the conventional geologic story.

The conventional geologic story renders the East Coast of North America which we called as the passive margin.

Answer: The protein in their diets

Explanation:

The lion gets its source of nitrogen to form protein in its diet.

Proteins are macronutrients that are present in foods. There are two types of proteins. Essential and nonessential. Non-essential proteins are synthesized in the body and essential proteins are needed to eat by taking food.

A lion is an animal, and animals synthesize some proteins in their body, and some proteins are to be taken from the food. Protein is necessary for the growth of the body. It gives strength to the body.

The protein synthesis is done in the cell of the animals. But the nitrogen, that the animals get is from the diet they eat which is meat and plants. It depended upon its diet. Some animals are carnivorous and some are herbivorous.

Therefore, the lions get their protein from their diet.

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.

Whether a molecule can cross the plasma membrane depends upon D. All of the above

Small nonpolar molecules, consisting of O2 and CO2, are soluble in the lipid bilayer and consequently can effectively cross cell membranes. Small uncharged polar molecules, which include H2O, can also diffuse thru membranes, however large uncharged polar molecules, inclusive of glucose, cannot.

Explanation: Molecules pass throughout the plasma/mobile membrane through diffusion. If they're not small sufficient, they need to break down by means of other substances, which include enzymes, which can be biological catalysts. If they are small enough, usually, the easiest way for them to move is through diffusion.

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.

Answer:

D

Explanation:

Answer:

This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. ... Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.

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.
