Answer:
Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.There are basically 2 types of changes that occur to the earth's surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process.
Explanation:
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. When it comes to changes on the Earth's surface, the main processes to take into account are plate tectonics and the rock cycle as well as the sea-floor spreading. ... These collisions causes mountains and volcanoes to form on the plate boundaries and thus changes the shape and form of the landmass
the genes stc1 and stc2, which share a common ancestor, are found in both zebrafish and humans. all four stc genes display similar patterns of exon and intron sequences. based on these facts, what is the most likely explanation for the origin of stc genes?
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
Despite having exons, prokaryotes do not have introns in their genomes.This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.

Which of the following statements about the law of independent assortment is correct?
A. It is the reason that dominant alleles are visible in the organism's phenotype.
B. It is the consequence of having two copies of each chromosome in somatic cells and one copy in gametes.
C. It describes the inheritance of different genes relative to one another.
D. It describes the inheritance of different alleles relative to one another.
The statement about the law of independent assortment which is correct is: C. It describes the inheritance of different genes relative to one another.
Independent assortment can be defined as a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
This ultimately implies that, the inheritance pattern of different genes with respect to another gene is given by the law of independent assortment.
In conclusion, the law of independent assortment describes how different genes separate with respect to another gene during the development of reproductive cells.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.
Answer:
Explanation:
The primary purpose of the systemic circuit is for blood to release carbon dioxide and pick up oxygen
The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.
What is pulmonary system?It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.
Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.
The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.
The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.
This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.
Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

What is Milton Erickson?He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.
Are the forces balanced or unbalanced?
Net force = ?
Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.
In physics, we can say that the net forces being applied to an object are balanced when the forces are
Equal in sizeApplied in opposite directionsApplied at the same time.The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.
Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

Which statement describes the way the paramecium reproduces asexually
A,it happens by cell division that include mitosis.
B,it happens by the formation of gametes.
C,it happens by cell division that include meiosis.
D.it happens by fertilization of an egg by sperm.
The statement that describes the way the paramecium reproduces asexually is as follows: it happens by cell division that include mitosis (option A).
What is asexual reproduction?Asexual reproduction is one of the two types of reproduction that involves neither meiosis nor fusion of gametes.
This means that in asexual reproduction, new offsprings are produced by a single parent. The new individuals produced are genetically and physically identical to each other i.e., they are the clones of their parents.
This is possible because the single parent cell divides mitotically to produce identical daughter cells.
Therefore, option A is correct regarding the way paramecium reproduces asexually.
