An animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system. The musculoskeletal system is what enables movement.
What is skeletal system?The skeletal system of the body has been composed of the bones and cartilage and they will perform many different types of function in the body of the organism. The cartilages along with the bones form the structural framework of the body. It also helps in the performing locomotory functions of the body. The brain signals the body of an animal to move by transmitting electrical impulses through the neurons.
It has the skeletal system of the body that helps in the walking, bending, sitting and as well as other movements of he body. It has been also serves as the barrier between the outer environment and internal organs and protects them from any exertion and shock.

After filling out the information above, answer this question in depth (at least 5 sentences). Use your notes as necessary. Why may chromosomal disorders be more detrimental than DNA mutations?
Answer: Chromosomal disorders are the disorders that are caused due to the presence of extra chromosomes, or absence of one or more chromosomes or specific part of the chromosomes. Mutation can be defined as the change that occurs in the genetic makeup of the organism either during copy of genome during replication or due to external factors like exposure to ultraviolet radiations, cigarette smoke, and due to carcinogenic agents.
Explanation:
The change in shape of the chromosome as compared to the normal one also exert influence over the functions. Down syndrome, Klinefelter syndrome, Turner syndrome, and others are the examples of the chromosomal disorders. These syndromes affect the normal functioning of the human being rendering it unfertile, rudimentary development of sex organs, development of traits in opposite sex, induce short life span, poor health, lack of proper mental development, and other abnormal characteristics in the effected individuals. On the other hand mutations are not always detrimental, only a small percentage of mutations can cause genetic disorders. Some mutations can change the genetic makeup by does not affect the functioning of the protein thus the physiological functions of the body are remained restored.

The diagram below shows a model of the movement of two tectonic plates. When the plates collide, one plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce -
fossil layers
volcanic islands
deep- sea sediment
seafloor spreading
Answer:
volcanic islands
Explanation:
As per the diagram given below that shows the model of the plate tectonics and shows the movement of the two plates one plate collides with another and the there moves under due to subduction.
The magma rises and can lead to the formation of volcanic islands. The island is a geologically active part of the plate that rises upwards and is formed by the process of sedimentation.Hence the option B is correct.

Love the pfp by the way! :D
The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.
What is International Astronomical Union?In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.
The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.
The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
Thus, the correct option is A.

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)?
A. Both children would not inherit the trait.
B.Both children would inherit the trait.
C. Each child has a 50% chance of inheriting the trait.
D. One child would inherit the trait and one child would not.
Answer:
C
Explanation:
autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait
Using the punnet square
X x
x Xx xx
x Xx xx
there is 2 X which means there is a 50% change that their child will get the trait
In the punnett square analysis, each child has a 50% chance of inheriting the trait.
The mother Xx has the trait and the father xx doesn't.
Using the punnet square
Xx xx
Xx Xx xx xx
There are just two traits which are Xx and xx which are in equal frequency
and proportion.
This therefore means that the children have a 50% chance of getting the trait.
