Answer:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

What can be inferred about a petrified log? the wood needed long ages before it could petrify the tree laid on the surface for long ages the petrified log looks like the original tree.
Answer:
the petrified log looks like the original tree.
Explanation:
A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as organisms, microorganisms, climatic conditions, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.
Depending on the preservation degree, a fossil can be useful for different studies about the past.

Often, one change in an ecosystem causes another change. Drag and drop the tiles to show the order in which this group of changes would happen.
Answer:
2. The Prey Population increases:
As a result of the predator population decreasing in size, the prey will no longer be hunted as much and so their population will rise.
3. The area is overgrazed due to overpopulation.
With so much prey in the system, they will eat up too much of the grass and flora which will lead to overgrazing.
4. The prey population decreases
With the and being overgrazed, the system will no longer be able to support the large number of prey. A lot of them will therefore starve to death which will decrease the pray population.
5.Invasive species dominate the ecosystem.
With less competition for resources from the natural plants in the area which have now been overgrazed, invasive species will dominate the system.

1. Write a statement that uses (correctly) the terms gamete, fertilization, and zygote. (2)
Answer:
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
what does divine creation mean? did charles darwin agree with this idea?
Answer:
The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and On the Origin of Species reflects theological views. Though he thought of religion as a tribal survival strategy, Darwin still believed that God was the ultimate lawgiver, and later recollected that at the time he was convinced of the existence of God as a First Cause and deserved to be called a theist.

ure told the shells are from oceanic organisms. How do you think this layer formed?
The layer would be formed by the strong currents as well as by waves slowly moving the shells to the share along with the other shells creating a layer of the shell as well as cliff of the rock.
What is sedimentary rock?Sedimentary rocks has been generally made up from the directly heat and these are formed when the deposition or the accumulation of the particles that are the organic or the minerals at the surface of Earth, later followed by the process of the cementation. The main feature of the sedimentary rock has been that they are formed in the multiple layers.The rocks has been made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.
Rock has been defined as when the mineral grains has been combined in the solid form and later they grow or take the shape of the cemented form has been known as the rocks.The rocks has been made up of more than one mineral and the size of the rocks are smaller or bigger it has been depends upon their constituents. Rocks has been divided on the basis of their formation by Geologists.There are mainly three kinds of rock and these are metamorphic, igneous, and sedimentary. The most durable substance is stone.

How do we know our current money has value? (5 points)
People talk about money a lot.
It is backed by gold.
People accept it in exchange for goods or services.
It has many security measures.
Answer:
The correct answer is - people accept it in exchange for goods and services.
Explanation:
Money is valuable because we know that it is "accepted." Money can be used to purchase goods and services even though it is no longer backed by gold. Security measures prevent counterfeiting but do not add value.
People know at that time that their current money has value when they accept it in exchange for goods or services, which is option C, as money is a medium of exchange.
The value of money is influenced by central banks. Different countries have different currencies, but the currency that is stable and has more security has more use. Money is also linked to the underlying economics, such as the ability of a country to buy and manufacture goods, thus increasing the economy. There are also many security measures, such as unique designs, special inks, holograms, etc., that are helpful for maintaining trust and confidence in the currency.

explain how sexual reproduction
leads to increased variation from parent to offspring?
Sexual reproduction is the process of reproduction which leads to increased variation from parent to offspring through crossing over and fusion of gametes.
What is Sexual reproduction?Sexual reproduction is the production of new organisms through the combination of genetic information of two individuals of different sexes (male and female). In most of the species, genetic information is carried on by chromosomes in the nucleus of reproductive cells which are haploid (n) called as gametes, which then fuse to form a diploid zygote.
Sexual reproduction results in genetic variation among different offspring. When a parent forms a gamete, only one of the chromosome from each of the homologous pair is included at random through crossing over. So, an offspring might inherit a different combination of chromosomes and alleles compared to the other offspring.

the earth mother in the japanese mythology
Answer:
Meoto Iwa (夫婦岩), the Husband-and-Wife Couple or the Wedded Rocks, are a couple of small rocky stacks in the sea off Futami, Mie, Japan. They are joined by a shimenawa (a heavy rope of rice straw) and are considered sacred by worshippers at the neighbouring Futami Okitama Shrine (Futami Okitama Jinja(二見興玉神社). According to local lore and Shinto beliefs, the rocks represent the union of the creator kami, Izanagi and Izanami. Although the above Meioto Iwa rocks are the most famous ones, there are many other meioto iwa rocks to be found elsewhere in the japanese landscape, see More Unfamiliar Glimpses of Japan’s page on “Meioto iwa on husband and wife rocks“.
Such iconography and the idea of a Creator-Couple or Cosmic Couple is rampant throughout the ancient prehistoric world, and particularly widespread among the tribes of the Austro-Asiatics, the Austronesians as well as the Polynesians.
