what are the 4 pairs of DNA bases that form in the double helix?
Answer:
Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

what formed the alps mountains
Answer:
The Alps arose as a result of the collision of the African and European tectonic plates, in which the western part of the Tethys Ocean, that was formerly in between these continents, disappeared.
Answer:
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn.

The frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.
What do you mean by Sonar?The sonar may be defined as a device that is used to find the distance, direction, and speed of underwater objects like water hills, valleys, icebergs, submarines, sunken ships, etc.
The universal wave equation states that the velocity of a wave is equal to the products of its wavelength and frequency.
v = λf
∴ f = v/λ
1500/0.032 = 46,875 Hz.
f = 4.6×[tex]10^4[/tex] Hz.
Therefore, the frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.

3/4 or 75%
Answer:
‼️A) 1/4 25% Chance‼️
Explanation:
If she gets the X chromosome with the hemophilia gene, she will have hemophilia. A man who has hemophilia and a woman who is a carrier have: a 25% (one in four) chance of having a son with hemophilia.
Answer:
50%

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
O density dependent
O density independent
O population dependent
O population independent
Answer:
Density independent is the correct answer
The type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.
What are density-independent factors?Density-independent factors are environmental factors that affect populations regardless of their size or density. These factors can include natural disasters such as forest fires, floods, hurricanes, droughts, and other extreme weather events. Other examples of density-independent factors include habitat destruction, pollution, and climate change. In the scenario described, a forest fire destroyed an area, which can lead to the decline of both tree and bird populations. The fire could kill the trees and destroy their habitats, making it difficult for the surviving trees to grow or reproduce.
Hence, the type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.
Answer:
B: Humans, chimpanzees, and other primates share a common ancestor.
Explanation:
According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.
Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.

An astronomer measures the distance to two stars using the parallax method. When comparing the placement of the stars six months apart, the star that is further away: A. Changes position the most B. Changes position the least C. Appears brighter D. Appears dimmer
Answer:
I would say A but im not 100% sure
Explanation:
The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.
What is the parallax technique?The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.
It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.
Therefore, the star located farthest will change its position the most.
