Final answer:
The object will move to the east with a net force of 20 newtons, due to the larger force acting in that direction after subtracting the smaller westward force.
Explanation:
When two forces act on an object in opposite directions, the object will experience motion in the direction of the net force.
In your case, you have one force of 50 newtons to the east and another force of 30 newtons to the west.
To determine the motion, you subtract the smaller force from the larger force (50 N - 30 N = 20 N) to find the net force.
The object will move to the east with a net force of 20 newtons.

Why is cell specialisation (differentiation) important for the development and growth of a healthy baby from a fertilised egg? Please help!
Answer:
Cell specialization is important in the development and growth of a healthy baby because cells differentiated to form different tissues, which organizes themselves to forms organs.
Explanation:
The development of an organism is divided into two processes, differentiation, and growth. The body contains two types of cells undifferentiated cells can become any cells, while differentiated cells have a specific role. Differentiation is the process in which cells change from an undifferentiated cell and become specialized (differentiated cell). On the other hand, growth is the process by which already differentiated cells reproduce to increase the size of the tissue.

Which of the following are the main external stimuli to which plants respond?
Check all that are true.
touch
light
oxygen
gravity
Plants primarily respond to touch, light, and gravity as external stimuli, using sophisticated systems like photoreceptors for phototropism and amyloplasts for gravitropism.
The main external stimuli to which plants respond are touch, light, and gravity. Oxygen is not typically considered a directional stimulus for plants. Plants have developed sophisticated systems to detect and respond to their environment. Phototropism is an example of how plants grow towards light using photoreceptors like cryptochromes and phototropins. Gravitropism describes how plants sense gravity; shoots exhibit negative gravitropism growing away from gravity, while roots exhibit positive gravitropism and grow towards gravity. In response to touch, certain plants can exhibit rapid movements or slower growth alterations, known as thigmotropism and thigmonasty.

Explanation: APEX answer
What would happen to a cell if cellular respiration stopped?
A. The cell would use water for energy.
B. The cell would not produce enough ATP.
C. Glucose breakdown would increase.
D. ATP production would increase significantly.
Answer:
B
Explanation:
Cellular respiration includes glycolysis that occurs on the cytoplasm of cells and Krebs cycle that occurs in the matrix of the mitochondria. The whole cellular respiration metabolic pathway produces a net of 36 ATPs (glycolsys produces a net of 2 ATPS and Krebs cycle a net of 34 ATPS). They use glucose as a substrate to harness the energy in its chemical bonds to produce the store this energy in ATPs, the energy currency of cells.
If cellular respiration stopped in a cell, it would lead to a lack of ATP production and energy for the cell's functions, the halt of pyruvate, citric acid, and carbon dioxide production, and a decrease in ATP production since glucose could not be broken down.
Explanation:If cellular respiration stopped in a cell, several things would happen.
ATP would not be produced, which means the cell would not have the energy it needs to carry out its functions.The production of pyruvate, citric acid, and carbon dioxide would also be halted, as they are products of cellular respiration.Additionally, without cellular respiration, the cell would not be able to break down glucose for energy and would experience a significant decrease in ATP production.In a strike-slip fault, the rocks on either side of the fault slip past each other sideways.

One environmentalist explained that a household could conserve the greatest amount of water by reducing water consumption in the laundry. Why is this information most likely to be incorrect?
A. environmentalists do not generally give reliable information
B.The information provided by environmentalists does not have scientific basis
C. the laundry is most house holds uses less then hundred gallons of water every year
D. scientific investigation shows that water use in the laundry room is about a fifth of a home's total usage
Answer: B.The information provided by environmentalists does not have scientific basis.
Explanation:
An environmentalist is a scientists who conducts political and ethical movements in order to make the human society aware about the use and conservation of resources, wildlife conservation, and protection of the environment against the harmful human activities.
According to the given situation, the environmentalists has just proposed the fact that the reducing the water consumption in the laundry can conserve the amount of water but he has not conducted any research. The proposed statement is not supported by any evidence in the form of data. Thus it can be said that the information is incorrect as it lacks scientific basis.
Answer:
it's actually not B, it is D. Scientific investigation shows that water use in the laundry room is about a fifth of a home's total usage.
Explanation:
based on watercalculator.org, it has been proven that washing machines only use about 16% of a home's total water usage. This can be seen as only a fifth of the total usage. The environmentalist is most likely incorrect because of this.

1 Which process allows for the growth and development of a multicellular organism? A. mitosis B. meiosis C. digestion D. elimination
2 Which organism has differentiated cells?
A.
amoeba
B.
chipmunk
C.
bacterium
D.
paramecium
The process that allows for the growth and development of a multicellular organism is mitosis. Hence, the correct option is A for 1. Among the options provided for 2, the organism with differentiated cells is a chipmunk. Hence the correct option is B for 2.
During mitosis, a single cell divides to produce two identical daughter cells, which then continue to divide and differentiate, leading to the growth and development of a multicellular organism. This differentiation process enables cells to take on specific roles, forming various tissues and organs necessary for the organism's survival and function. Differentiated cells are characteristic of complex, multicellular organisms such as animals, including chipmunks. These organisms have various types of cells that perform different functions, unlike unicellular organisms or those with undifferentiated cells.Complete this sentence.

List the charge mass and location of each of the subatomic particles found within atoms
Final answer:
Atoms consist of protons, neutrons, and electrons. Protons (+1 charge, ~1 amu) and neutrons (0 charge, ~1 amu) are located in the nucleus, while electrons (-1 charge, ~1/2000 amu) orbit in shells around the nucleus. The number of protons defines the atomic number, while isotopes differ in neutron numbers.
Explanation:
Properties of Subatomic Particles:
The atom consists of three types of subatomic particles: protons, neutrons, and electrons. Protons possess a positive charge (+1) and are found in the nucleus of the atom. The mass of a proton is approximately 1 atomic mass unit (amu).
Neutrons do not have any electrical charge and are also located in the atomic nucleus along with protons. Similar to protons, neutrons have a mass close to 1 amu.
Electrons are negatively charged particles (-1) that are found in 'clouds' or shells around the nucleus. The mass of an electron is much smaller, about 1/2000th of an amu. These particles are responsible for the chemical properties and reactivity of an element.
Arrangement of Subatomic Particles within an Atom:
Protons and neutrons collectively form the nucleus at the center of an atom.Electrons move around the nucleus in various energy levels or shells.The number of protons defines the atomic number of an element.Isotopes of an element have the same number of protons but different numbers of neutrons.

bacterial cells may have all of the following except a
a. Glycocalyx
b. nuclear membrane
c. cytoplasmic membrane
d. peptidoglycan cell wall
A Bacterial cell may have all of the following except a nuclear membrane. Thus, the correct option for this question is B.
What is Bacteria?Bacteria may be defined as a type of unicellular microorganism that significantly lacks a well-defined nucleus and other membrane-bound cell organelles.
The cell wall of bacteria is made up of peptidoglycan. It is an essential protective barrier for a bacterial cell that surrounds the cytoplasmic membrane as well. The Glycocalyx is the outermost layer of the three-layered cell envelope found in many bacterial species. It limits the access of certain molecules to the extracellular membrane.
The cytoplasmic membrane in the bacteria is composed of an approximately equal proportion of lipids and proteins. Phospholipids are the main lipid components.
Therefore, a nuclear membrane is significantly not present in bacterial cells. Thus, the correct option for this question is B.

What combination of boundary type and crust type creates enormous mountains?
Enormous mountains are often created at convergent boundaries involving continental crusts. An example of this is the formation of the Alps due to the collision of the African and Eurasian plates. The mountains' appearance is further shaped by erosion from ice and running water.
Explanation:The creation of enormous mountains typically involves convergent boundaries and continental crust types. Convergent boundaries occur when two tectonic plates collide or move towards each other. This phenomenon often leads to the formation of mountain ranges. A vital example to understand this concept might be the formation of the Alps, which was due to the collision course of the African plate and the Eurasian plate.
The type of crust involved also plays a crucial part in the formation of mountains. Earth's crust comprises two types: the oceanic crust, which is denser and thinner and the continental crust, which is thicker and less dense. When a collision involves two pieces of continental crust which are equally resistant to subduction (sinking into the mantle), the result is a massive mountain range. These ranges are further sculpted and eroded by ice and running water, bringing about the sharp, jagged appearances we typically associate with mountain peaks.
