Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

Belinda asked her teacher, "What could make turtles go faster?"
Her teacher replied, "I don't know. See if you could find out."
So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week
she had a turtle race. She kept a record of the times and realized that she was
wrong. In fact, all the carrot-eating turtles finished last.
How was the dependent variable measured?
The amount of sleep the turtles received
How fast the turtles ate
The turtle's speed in the race

What cannot form when two plates collide?
Volcanoes
⊝
Deep Sea Trenches
⊝
Mountain Ranges
⊝
Rift Valleys
Answer:
D. Rift Valleys
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.
Hence, Rift Valleys cannot form when two plates collide because they are formed only when the tectonic plates of earth rift or move apart. Also, Rift Valleys are found at the bottom of oceans and on land.

What are the chromosomes called when they look like Xs
Answer:
I think you're referring to the Metaphase...
Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....
The chromosomes are called "sister chromatids" when they look like Xs.
What are these chromosomesDuring cell division, specifically during the phase called mitosis, chromosomes replicate themselves, resulting in two identical copies joined together. Each of these copies is referred to as a sister chromatid. Sister chromatids are held together by a structure called the centromere, giving the appearance of an X-shaped chromosome.
The X-shaped appearance of chromosomes is a characteristic feature observed during certain stages of cell division, particularly during metaphase and anaphase, when the chromosomes are highly condensed and visible under a microscope.

How are the inner and outer planets different? Use an example to support your answer.
ʕ •ᴥ•ʔ *Rawr*
Answer:
THE INNER PLANETS
Mercury, Venus, Earth and Mars
THE OUTER PLANETS
Jupiter, Saturn, Uranus and Neptune
Small size
Earth is the largest of the Inner Planets, with a diameter of 12,756 km (7,926 miles). Mercury is the smallest with a diameter of 4,878 km (3,031 miles)
Huge!
Jupiter, the largest planet, has a diameter of 142,984 km (88,846 miles). Neptune is the smallest of the Outer Planets with a diameter of 49,532 km (30,779 miles)
Have solid surfaces and thin/no atmospheres
In theory, it would be possible to stand on each of the Inner Planets, although you would only survive on Earth.
Balls of gas with no surface
Most of the Outer Planets are made of gas. It is likely that they have a much smaller solid or liquid centre. It would be impossible to stand on any of the Outer Planets.
Greater Density
The size and composition of the planets is caused by the density of the elements that make up the planets. The elements in the Inner Planets are more closely packed together, causing them to be smaller and solid.
Smaller Density
Despite being larger, the elements that make up the Outer Planets are less densely packed together causing them to be quite light for their size.
Varied atmospheres
The contents of the atmospheres of the Inner Planets varies from planet to planet. Mercury has no atmosphere although Sodium and Helium can be detected above the surface. Venus' atmosphere is mostly Carbon Dioxide with a very small amount of Nitrogen. Earth's atmosphere is mostly Nitrogen with a smaller amount of Oxygen and even smaller amounts of other gases. Mars has a similar composition of carbon dioxide and nitrogen as Venus although has a much thinner atmosphere.
Similar atmospheres
The atmospheres of the Outer Planets consist mostly of Hydrogen and Helium, with Methane also being present in the atmospheres of Uranus and Neptune. Other gases are present although in much smaller quantities.
Known by the ancients
The existence of the Inner Planets has been known about for thousands of years. The earliest astronomers didn't know that the four objects (including Earth) were planets, but they knew they existed.
Not known by the ancients
Of the Outer Planets, only Jupiter and Saturn were observed by ancient astronomers. The existence of Uranus and Neptune was not known until relatively recently. Uranus was discovered in 1781 and Neptune in 1846.
Spin slowly
Compared to the much larger Outer Planets, the Inner Planets spin quite slowly. Earth spins the quickest, taking 23 hours and 56 minutes to spin on its axis. Venus takes 243 days to spin on its axis, spinning in an opposite direction to the other planets.
Spin quickly
All of the Outer Planets spin quicker than the Inner Planets. Uranus spins slowest, taking 17 hours and 14 minutes to spin on its axis. Jupiter takes only 9 hours and 55 minutes to spin on its axis. This rapid rotation causes Jupiter and Saturn to appear squashed, wider across the equator than from top to bottom.
Orbit the Sun quickly
Because they are quite close to the Sun, the Inner Planets complete an orbit quickly. Mercury takes only 88 days to orbit the Sun. Mars takes 687 days.
Orbit the Sun slowly
The Outer Planets orbit the Sun from millions of miles and have a much greater distance to cover to complete an orbit, so take much longer to do so. Jupiter takes almost 12 years to complete an orbit and Neptune takes over 164 years.
Few Moons
Only Earth and Mars have moons orbiting them. One moon orbits Earth and two small moons orbit Mars.
Lots of Moons
All of the Outer Planets have many moons orbiting them. There are 63 moons known to orbit Jupiter, 60 orbiting Saturn, 27 orbiting Uranus and 13 orbiting Neptune.
No rings
None of the Inner Planets have rings orbiting them
Rings
All of the Outer Planets have rings orbiting them. The rings are thin discs of dust and rocks possibly caused by moons being broken up or not being completely formed while orbiting the planet. Saturn has the most visible ring system of any of the planets.
Multiple space craft visitors
Due to being close to Earth, there have been several missions to the other Inner Planets, especially to Mars and Venus. Mercury has been visited by two spacecrafts.
All Outer Planets visited by one space craft
There have been multiple visits to Jupiter and Saturn, but Uranus and Neptune have only been visited once. This was by Voyager 2 (which also visited Jupiter and Saturn).
