For this assignment, consider the processes that create coastal rock formations. While these processes create beautiful and interesting rock formations, they are also often highly destructive. Think for example what could happen to a town that is near the sea and has buildings being exposed to the same forces that create sea cliffs, arches, and stacks. How do you think those buildings stand up against the forces of the waves? Make a discussion posting to describe what you think happens to buildings exposed to sea erosion and then suggest ways that the destruction associated with this force can be stopped for people who live in towns near the coast.
After you make your post, comment on at least one of the posts of your classmates.

Fungus cells: cell walls, nuclei, mitochondria, endoplasmic reticulum, Golgi apparatus, endosomal vacuoles, various types of vesicles, and peroxisomes.
Plant cells: chloroplast, cell wall, plastids, and a large central vacuole.
Animal cells: nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
Answer:
1) Ribosomes: Are the organelles responsible for synthesizing all the proteins the protist will need
Mitochondria: which are the organelles responsible for turning food into energy the cell can use
Chloroplasts, which are the organelles that are able to capture sunlight
____________________________________________________________
2) Mitochondria: Developmental and morphogenetic switches such as hyphal differentiation and biofilm formation, adaptation to stress, cell wall biosynthesis and structure.
Endoplasmic reticulum: harbors several of the enzymes involved in the biosynthesis of ergosterol, an essential membrane component
Golgi apparatus: performs crucial functions in the sorting and processing of proteins destined for secretion
____________________________________________________________
3) Chloroplast: Allow plants to capture the energy of the Sun in energy-rich molecules and carries out the process of Photosynthesis.
Cell wall: The cell wall surrounds the plasma membrane of plant cells, providing structure and protects the plant from mechanical and osmotic stress.
Plastids: responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis
Vacuole: Simply helps maintain water balance, usually large and takes up most of the space in a plant cell.
____________________________________________________________
4) Nucleus: Controls and monitors the activities of the cell and carries the genes, structures that contain the hereditary information for their offspring.
Mitochondria: Generates most of the chemical energy needed to power the cell's biochemical reactions.
Endoplasmic reticulum: Serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
Golgi apparatus: Helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicle: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another
Vacuole: Are generally small and help dispose waste products in the cell.
Ribosomes: Link together specific amino acids to form polypeptides and they export these to the cytoplasm.

22) Net force is the total of all forces acting on an object. When a force is balanced and the object does not move, the net force is equal to what: A) 0 B) 10 C) 100 D) The weight of the object
Answer:
A) but be sure and read the answer.
Explanation:
If the object does not move at all, (that's an important restriction) the net force = 0. That being so, the acceleration must be 0 as well. But there is no law saying that there cannot be a constant motion and that's why the restriction is important.

a group of engineers have launched a space probe from earth that will land on the surface of Mars. how will the force of gravity from mars affect the space probe?
A) the force of gravity from Mars will not pull on the space probe until it reaches the planets surface.
B) the force of gravity from Mars will stop pulling on the space probe when it reaches the planet
C) the force of gravity from Mars will pull more strongly on the space probe as it gets closer to Mars.
D) the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is
Answer:D
Explanation:
The force of gravity from Mars will pull on the space probe the same amount no matter how far away it is, so option D is correct.
What is gravity?All material objects in the universe are subject to the force of gravity, also known as gravitation. The force of gravity tends to draw any two non-zero mass objects or particles toward one another. Subatomic particles and galaxy clusters are both affected by gravity, as are objects of all sizes.
Due to the law of gravity, or gravitation, which draws all objects with mass in its vicinity toward it, Mars' gravitation is a natural occurrence. Due to the planet's lesser mass, its gravity is weaker than that of Earth. On Mars, the gravitational acceleration fluctuates, but on average it is 3.72076 m/ s² (or around 38% of Earth's).
Therefore, the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is.

Biology of awerness. Based on information in the articale, what is the most likely reason all organisms adapted to havea the trait of awarenes
Answer:
Awareness was selected because it was beneficial to organisms in particular environments.
Explanation:
Based on the article, natural selection is a phenomenon that recognizes and allows traits that are useful to an organism and that would be favorable for it to be passed from one generation to another.
Natural selection marked awareness as a useful trait that would be beneficial for organisms because it helped them adapt well to the particular environments that they found themselves. For example, this ability helped an organism to be able to recognize where it could get food and light in its environment.
A 80 kg person buys a scale at a mall that reads weight in Newtons and can’t wait to try it out, so they open the scale on an elevator. What would the scale read if the elevator was moving upward at 6.2 m/s2?
Answer:
The scale read 1280 N.
Explanation:
Given that,
The mass of a person, m = 80 kg
We need to find the scale reading when the elevator is moving upward at 6.2 m/s².
We know that, when an elevator moves up, the reading on the scale is given by :
N-mg=ma
N=m(a+g)
Put all the values,
N = 80(6.2+9.8)
= 80(16)
= 1280 N
Hence, the scale read 1280 N.
If the work required to speed up a car from 11 km/h to 21 km/h is 6.0×103 J , what would be the work required to increase the car’s speed from 21 km/h to 33 km/h
Explanation:
We need convert the velocities first to m/s and we get the following:
v2 = 21 km/hr = 5.8 m/s
v1 = 11 km/hr = 3.1 m/s
We need to find the mass of the car also for later use do using the work-energy theorem:
[tex]delta \: w = \frac{1}{2} m(v \frac{2}{2} - v\frac{2}{1} )[/tex]
6.0x10^3 J = (0.5) m [(5.8)^2 - (3.1)^2]
or
m = 499.4 kg
Now we determine work needed delta W to change its velocity from 21 km/hr to 33 km/hr
v2 = 33 km/hr = 9.2 m/s
v1 = 21 km/hr = 5.8 m/s
delta W = (0.5)(499.4)[(9.2)^2 - (5.8)^2]
= 1.3 x 10^4 J

When rutherford bombarded thin gold foil with a-particles,he found that some a-particles were deflected through large angles. Which statement explains this deflection?
Answer:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Explanation:
In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.
The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,
V_atom / V_nucleo = 10⁴
Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.
In summary, the phrase that describes the process is:
the nucleus of the atom you have conserved almost all its mass in a very small volume
