The discovery of new elements such as gallium demonstrated the predictivinnes ability of the periodic table proposed by Dimitri Medeleiev.

Mendeleieve observed that, when the elements were organized by ascending atomic mass, a periodic pattern of the properties appeared. The elements arranged in sane columns showed similar properties. So Mendeleiev predicted the existence of elements that had not been discovered but that he affirmed that should have some properties given the position that they would occupy.

Gallium is an example of one of the elements that was discovered and exhibited the properties predicted by the space that it occupies in the periodic table.

Self-portraits can help you learn about positioning people in a photograph.

<em>1.) True</em>

<em>The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.</em>

<em>2.) True</em>

<em>While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to. </em>

<em>Hope this helps you, and have fun with whatever it is you are doing with your camera.</em>

ch4aika [34]

Sea otters are a symbol of the beauty and diversity of marine life that can be found along the California coast.

They're also important to the health and stability of coastal marine ecosystems, hence they're considered critical species.

Sea urchins and other invertebrates that graze on giant kelp provide food for them.

Without sea otters, kelp forests and, with them, a variety of animal species that rely on kelp environments for existence would be destroyed.

Kelp forests also safeguard the coast from storm surges and absorb a significant amount of dangerous carbon dioxide from the atmosphere.

Sea otters are especially important since their health reflects the health of the coastal waterways of California.

natulia [17]

Answer:

The correct answer is - XTXt

Explanation:

In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.

The allele for yellow allele = XT (it is dominant allele)

The allele for black coat = Xt (it is recessive allele)

The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.

In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.
