Describe some of the reasons for exploring the mid-Cayman ridge.
Answer:
Life on Earth goes back almost 4.1 billion years, but photosynthesis as characterized by cyanobacteria only appeared around 3.5 billion years ago (Ga). Since life on Earth predates photosynthesis, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.
Explanation:
This was the answer on edge
The major reason for exploring the mid-Cayman ridge is to provide
information on what those life forms looked like.

How would a lack of contact inhibition result in the growth and spread of cancerous cells?
Explanation:
Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells
Contact inhibition is the property of normal healthy cells where the cells cease growth after coming in contact with each other. A lack of this property results into uncontrolled growth of cells.
What is Contact inhibition?
Contact inhibition is the property of normal healthy cells which enables the cells to cease proliferation and growth when they come in contact with each other. This property is lost by the cell when the cells undergo malignant transformation. As a result, this leads to uncontrolled proliferation and solid tumor formation in the body.
In the in-vivo culture of cells, contact inhibition arrests cell growth and as a result, normal cells stop proliferating when they form a monolayer in the culture dish. Contact inhibition is a powerful anticancer mechanism which is lost in cancer cells.

Answer:
Maritime transport and fluvial transport, or more generally waterborne transport, is the transport of people or goods via waterways. Freight transport by sea has been widely used throughout recorded history.
Explanation:
Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults

Answer:
40kg
Explanation:
F=M*A
M=F\A
M=400\10
M=40kg
The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2 is 40 kg.
What is acceleration due to gravity?The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.
It is a vector quantity whose direction, strength, or magnitude match a plumb bob.
According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.
We know that,
F = m x g
m = f/g
Where,
F = force
m = mass
g = acceleration due to gravity
Given that,
F = 400N.
g = [tex]10m/s^2[/tex]
So,
m = 400/10
m = 40 kg.
Thus, the mass is 40 kg.

How is an ectotherm most likely to maintain homeostasis during cold weather?
A. By sitting on a warm surface
B. By lying in the shade
C. By shivering
D. By sweating
Ectotherm describes the animals that use external sources to maintain their body temperature. They will maintain their homeostasis in cold weather by sitting on a warm surface. Thus, option A is correct.
What are ectotherms?Ectotherms are animals that cannot regulate their body temperature on their own and are dependent on external sources to maintain their body heat.
They have to depend on environmental sources like a warm place to maintain their body temperature during the cold weather. They cannot sweat or shiver to maintain homeostasis.
Therefore, during the cold, ectothermic animals sits on warm surfaces to maintain homeostasis.

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)
Answer:
The no. of heterozygous carriers = 0.0392
Explanation:
From the given information:
The incidence of this recessive disorder i.e. q² = 1/2500
q² = 0.0004
q = 0.02
From Hardy Weinberg's Equilibrium.
p + q = 1; &
p² + 2pq + q² = 1
∴
p + 0.02 = 1
p = 1 - 0.02
p = 0.98
So, the numbers of heterozygous carrier 2pq is:
= 2 × 0.98 × 0.02
= 0.0392

Some chemical reactions release energy. Others store energy. What important chemical reaction stores energy?
Answer: endothermic reaction.
Explanation: A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart.
Chemical reactions which release energy are called Exothermic reaction whereas the reaction which store energy are called Endothermic reaction. The energy is stored in the form of chemical bonds.
What is Chemical reaction?A chemical reaction is a process in which chemical transformation of one set of substance is converted into another type of substance.
Chemical reactions are of two types on the basis of energy transfer: Exothermic reaction and Endothermic reaction. An exothermic reaction is the chemical reaction in which the product is formed with the release of energy in the form of heat. For example: Breakdown of glucose through cellular respiration. An endothermic reaction is the chemical reaction in which the product is formed which stores energy in the form of chemical bonds. For example: The formation of glucose.

The gradual ______________________ of one plant community by another through natural processes over time.
Answer:
The gradual replacement of one plant community by another through natural processes over time.
Explanation:
Succession is a process dominated by plants, in which communities change as a function of the changes experienced by plant communities, that is, it is the natural evolutionary process by which some species gradually take the place of others less adapted to the environment. Ecological succession tries to predict the changes that occur in ecosystems over long periods of time, that is, the temporary directional change in the composition or structure of a community over time.
please HELP me i cant fail this class What are the two forces of gravity that contribute to tectonic plate movement at mid-ocean ridges?
Ridge subduction and slab flight
Ridge slip and slab slide
Ridge push and slab pull
Gravity does not pull them
Answer:
"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."
Explanation:
Does this help?
It is because of ridge slip and slab slide i the divergent plate boundaries, where tectonic plates movement creates mid ocean ridges.
What is divergent boundary?Divergent plate boundaries are the regions where the tectonic plates are diverging from one another, this is known as a divergent plate boundary. Above upward convection currents, this happens.
The lithosphere's base is pushed upward by the rising current, which lifts it off the ground and flows lateral currents beneath it. When an oceanic lithosphere border diverges, the rising convection current beneath raises the lithosphere, creating a mid-ocean ridge.
The plate material above is dragged along in the flow direction by this lateral flow. The overlaying plate is thinned out, fractures, and pulls apart at the peak of the uplift.
Hence, in fact it is not by the gravitational pull but by the ridge slip.
