Continental drift is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Answer:
Continental Drift-was a theory that explained how continents shift position
on Earth's surface.
Seafloor Spreading-helps explain continental drift in the theory of PLATE TECTONICS. when oceanic plates diverge, tensional plates causes fracture to occur in the lithosphere.

Characteristics of mitosis include
the most common kind of cell division
four daughter cells produced when parent cell divides
same number of chromosomes in each daughter cell as in the parent cell
different DNA in the daughter cell than in the parent cell
Final answer:
Mitosis is the process by which a single parent cell divides to produce two daughter cells that are genetically identical to each other and the parent cell, with the same number of chromosomes.
Explanation:
Characteristics of mitosis include:
The most common kind of cell division
Same number of chromosomes in each daughter cell as in the parent cell
Mitosis is a process where a single parent cell divides to produce two genetically identical daughter cells. This is known as somatic cell division.
During the stages of prophase, metaphase, anaphase, and telophase, the chromosomes are equally separated, ensuring that each daughter cell obtains an exact copy of the DNA, with the same number of chromosomes as the original cell. This is typically seen in diploid cells, which would have 46 chromosomes or 23 pairs in humans.
This ensures genetic continuity and is critical for growth, development, and repair of multicellular organisms. In contrast, meiosis results in four genetically distinct daughter cells with half the number of chromosomes.
The long-term increase in the average temperature on Earth is referred to as _[blank]_.
global cooling
ozone cooling
global warming
ozone warming
Answer:
global warming
Explanation:
The long term increase in the average temperature on earth is known as global warming. It occurs due to the presence of carbon dioxide (CO₂) and other green house gases in the earth's atmosphere. CO₂ molecules have tendency to trap radiations from sun. This is the reason why the earth's atmosphere remains warm even after sun set. Because of this, the average temperature of earth is rising which is mainly responsible for melting of glaciers and has many other adverse effects on animals, natural resources, plants etc.
What is the difference between germline mutations and somatic mutations? A. Germline mutations are caused by mutagens in the environment, while somatic mutations are inherited from a parent. B. Germline mutations can't be passed on from a parent to a child, while somatic mutations can. C. Germline mutations can cause serious problems, while somatic mutations don't. D. Germline mutations are inherited from a parent, while somatic mutations are caused by mutagens in the environment.
Answer:
Option (4).
Explanation:
Mutation may be defined as the sudden, inheritable change in the DNA sequence of the organism. Two main types of mutation are germ line mutation and somatic mutation.
Germ line mutation occur in the germ cells of the organisms and can be inherited to the other generation. Somatic mutation occurs in the somatic cells and cannot passed to the next generation. Somatic mutation may be caused by the mutagens present in the environment.
Thus, the correct answer is option (D).
Germline mutations are inherited from a parent, while somatic mutations are caused by mutagens in the environment. Therefore option D is correct.
Germline mutations refer to genetic changes that occur in the DNA of germ cells, which are the cells that give rise to eggs and sperm. These mutations can be inherited from a parent and are present in all cells of an individual's body, including the cells that make up the reproductive system.
As a result, germline mutations can be passed on from one generation to the next, affecting offspring. These mutations play a significant role in hereditary diseases and genetic disorders.
On the other hand, somatic mutations occur in the DNA of non-reproductive cells, known as somatic cells.
These mutations can arise during a person's lifetime due to various factors, including exposure to environmental mutagens such as radiation, chemicals, or errors in DNA replication.
Thus, the main difference between germline mutations and somatic mutations is that germline mutations are inherited from a parent and can be passed on to offspring, while somatic mutations occur in non-reproductive cells and are not passed on to future generations.

Which of the following is true about the solar wind? Select all that apply
the solar wind blows dust around on the Moon.
the solar wind interacts with Earth's magnetosphere.
the solar wind only interacts with the Earth and its moon.
the solar wind may be the source of water on the Moon.
Answer:
the solar wind interacts with Earth's magnetosphere
Explanation:
The Earth's magnetosphere is the zone in which the solar wind interacts with the magnetic field of the Earth. It is acts as a protective layer for the Earth, and without the magnetic field, the magnetosphere would not exist, thus the solar wind would mostly likely destroy everything living on the planet. The solar wind originates from the corona of the Sun. It is basically consisted of electrons and protons that are highly energized and charged, coming outwards of the Sun as a stream. They have enormous temperature of up to one million C degrees, and travel very quickly at speeds of around 900 km/h. The solar winds are also responsible for the formation of the natural phenomenon known as aurora borealis.
How does the temperature of water change if you heat it after it has already reached the boiling point?
A. it does not change
B. it increases
C. it decreases
D. it increases then slowly decreases
Answer:
A. it does not change
Explanation:
the temperature of water does not change if you heat it after it has already reached the boiling point
after boiling point the temperature becomes constant and the heat energy supplied is used for vaporization .
Answer:
A. it does not change
Explanation:
This is because when water is heated to its boiling point of 100degrees celsius, more energy is usually needed to convert the liquid to gas so the additional heat helps in this conversion.
Water temperature doesn’t change when it reaches the boiling point till all the water evaporates into the atmosphere. When there is no more water, the temperature increases according to the nature of the container.

Ah, my favorite subject, astronomy. What you are looking at here is NGC 1427A, a category Irr I galaxy, meaning Irregular (kinda.) The galaxy is somewhat structured but has an overall sloppy shape, making it irregular. Irr II galaxies have little to no shape what so ever, they are just clouds, but since this galaxy does have a bit of structure, it's only a Irr I. The image there was taken by the Hubble Space Telescope, basically a remote-controlled observatory orbiting as a satellite around the Earth. I should also say that this galaxy is not an elliptical galaxy, as it is obviously not very smooth. Elliptical galaxies are sphere shaped galaxies that look like huge star clusters, with a bright core in the center, and have a nice smooth appearance as if it was a glowing ball of mist. This galaxy we see in the picture is rather more, a glowing blob of clouds. I hope all of this extra information you probably didn't need kept you somewhat interested. Sorry for a late answer by the way.
