as Australia? Choose the two correct answers.
Answers
Answer:
Australia has large amounts of sandstone and silica.
and
Opal can only be formed where an ocean comes in contact with land.
Explanation:
because it needs standstone and a ocean to be able to create opal
Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).
What is an Opal?Opal is defined as a hydrated amorphous form of silica where the water content can range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous property, opal is classified as a mineral, in contrast to the crystalline forms of silica, which are considered minerals.
Opal is arguably the most unique, diverse and beautiful, it does not have a defined crystalline structure which takes on many shapes and colors and thus is very unpredictable.
It can be formed where the sea is in contact with the sand, as in places such as those in Australia.
Thus, Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).

5. When is extinction of a species most likely to occur?
A)when environmental conditions remain the same and the proportion of individuals within the species that lack adaptive traits increases
B)when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce
C)when environmental conditions change and the adaptive traits of the species favor the survival and reproduction of some of its members
D)when environmental conditions remain the same and the proportion of individuals within the species that possess adaptive traits increases
Answers
Answer:
Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
The extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
If the members of species do not have adaptive traits to survive and reproduce, they will definitely become extinct in near future.
This is because the relative fitness is directly related to the appearance or existence of particular species in the habitat.
Therefore, the extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.

What is the benefit of using sunscreen when working outside every day?
Answers
Answer:
Not only does it protect from UV rays, it also works to reduce the appearance of pores and fine lines over time, so you're actually improving your skin while wearing it.
Explanation:
Answer:
It prevents cancer.
Explanation:
UV rays penetrate the many layers of the epidermis, reaching the deep layers of our skin, which is meant to be protected. This activates pigment cells, releasing Melanin and darkening the skin.
When the UV rays penetrate these deep cells, it reacts similarly to radiation, denaturing and breaking apart DNA. If enough damage is done and the cell becomes irreparable a tumor forms.
Consistent exposure to UV rays has detrimental effects because it puts your skin cells through this same stress every day.

reproduce more quickly than others?

B.) The seeds are able to fertilize and grow in the soil at a faster rate.
C.) The root may grow horizontal rhizomes that make new shoots.
Answers
Answer:
C.) The root may grow horizontal rhizomes that make new shoots.
Explanation:
Plants like grasses able to reproduce more quickly than others because their roots grow horizontal rhizomes into a new shoots. These grasses spreads in the soil due to movement of rhizomes horizontally and grows its shoot with this movement. This spreading helps the grasses to make carpets in the grounds and has the ability to grow faster than other plants so we can say that growth of horizontal rhizomes is responsible for quick growth of grasses.

a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?
Answers
Answer:
hunting, the predator is in the middle of the food chain
Explanation:
hunting can WIPE OUT species as shown by the dodo bird in the past.
food chains often work as 1-2-3 or 1-2-3-4 in levels.
A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.
What happens if in a particular food web a new prey animals are introduced?If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.
Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.
Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

Explain the process of photosynthesis in a plant in detail.
Answers
Answer:
Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. The chemical energy is then stored as sugar. During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food).
Explanation:
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
Answer:
The roots absorb water and nutrients. Water is carried to the leaf by the xylem in the stem. Carbon dioxide enters the leaf through the stomata. Energy from the sun is captured by chlorophyll in the chloroplasts. The process begins once these three reactants are present. Sunlight provides energy for a series of chemical reactions. Molecules break apart and join with other molecules to form glucose, which is a sugar or food for the plant, and oxygen, which is released into the air.

Is the Amazon Rainforest Resilient or Fragile to change and why?
I thought Resilient because the rainforest has changed over time because it was fragile before.
Answers
Answer:
Resilient.
Explanation:
Amazon Rainforest is more Resilient to change because Amazon rainforest has evolved over millions of years. Amazon rainforests may be more resilient to climate change induced by carbon dioxide due to storing a lot of carbon as living biomass. The climate change is unable to change the Amazon rainforest due to their dense vegetation but if the rainfall patterns changes means the Amazon rainforest experience less rainfall due to climate change so it has a change this Amazon rainforests.
