Answer:

1) Inti menghilang.

2) Kromatid menuju bidang ekuator.

Penjelasan:

Selama fase pertama mitosis i. e. profase di mana replikasi menjadi kromatid terjadi dan berubah menjadi kromosom sementara nukleolus menghilang dan terjadi pemecahan selubung inti. Setelah profase, metafase dimulai di mana kromosom menjadi terlihat di sitoplasma sel dan bergerak menuju tengah atau ekuator sel.

Which feature of earth is created at mid ocean ridges
777dan777 [17]

The correct answer is - underwater mountain ranges.

The mid-ocean ridges are actually underwater mountain ranges, which usually are very long, in fact the longest mountain range on Earth is created on the divergent boundary between the Eurasian and North American tectonic plates and between the African and South American tectonic plates. At the divergent tectonic boundaries we have the creation of new crust which rises from the mantle and fills in the gap between the tectonic plates. Because of the big amount of magma and high pressure, very big and long underwater mountain ranges are formed.

Hydroelectric dams are often used to generate
inysia [295]

Answer:

Potential & Kinetic energy.

Explanation:

The water used gains potential energy overtime before it is converted to mechanical (or kinetic energy). This can be explained by the water having increased potential energy as it flows at an equal altitude, but converting to kinetic energy as it flows downhill, or over the dam.

This kinetic (or mechanical) energy is then converted to traditional electricity. This process is also an example of a renewable resource being utilized for everyday things (such as powering cars, homes. or charging batteries).

Two selectively permeable sacs A and B were submerged in a 45% glucose solution that was contained in a beaker. Sac A contained
Vesnalui [34]

Answer:

Option a. Only from Sac A to the beaker is correct.

Explanation:

As beaker contains glucose which is a monosaccharide and Sac A also have glucose in it, So, therefore glucose from sac A will move into beaker through the process of OSMOSIS.

Sac A (15% glucose) is less concentrated as compared to beaker (45% glucose) therefore this phenomenon will occur. (See attached image for more detailed and graphical explanation)

The most recent species from which two different species have evolved is a parent.
Dimas [21]
A true

<span> Before agriculture was developed people mostly were nomadic in nature. They moved from place to place in search of food. Some of them were groups of hunter gatherers as well. When agriculture started people also started to settle down in groups. This led to the development of civilization and in modern day cities and towns. The first agricultural practices were started beside the river banks due to the reason that the soil was very fertile and water for irrigation was also easily available. </span>

<h3>What is fitness?</h3>

<u>Fittest </u>is the term describes living things that are best suited to their environment.

Species that survive are the ones that <u>adapt</u>, make or meet changes.

Florida has a rich <u>fossil </u>record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the <u>giant sloth</u> and the<u> </u><u>saber-tooth tiger</u>.

Some animals unable to adapt to the changing environment became <u>extinct </u>.

Living things <u>mutate </u>over time to meet their changing environment.

This biologist, Darwin, studied <u>evolution </u>in the 1800s.

The <u>glyptodont </u>was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about<u> </u><u>natural selection</u>.

Nature selects the <u>fittest </u>for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a <u>mutation</u>.

Oldfield mice show <u>variation </u>in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called <u>adaptation</u>.

Evolution is a controversial theory that has survived much <u>criticism</u>.
