Answer 1

Answer:  

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. It was proposed by Alfred Wegener.

Explanation:

Just took the test on A P E X, it's right. Hope this helps :)

Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.

What are the different layers of the atmosphere?

The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.

In the troposphere, the temperature rises from bottom to top.  The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.

The atmospheric layers protect the life on Earth.

how do mutations affect our communications?​

Answers

Explanation:

When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.

2. Non-polar

3. Non-polar

4. Fatty acids

5. Saturated fats

6. Unsaturated fats

Explanation:

LIPIDS are one of the four major biomolecules in living systems. A form of lipids are fats which constitute most lipids i.e. predominant. Lipids also includes fatty acids, steroids and other molecules.

Lipid biomolecules readily dissolve in POLAR solvents such as hexane and chloroform. Because of their insolubility in water (polar solvent), fats and other biomolecules in this class are said to be NON-POLAR.

Triacylglycerols, also known as triglycerides, are forms of fat that is composed of a glycerol molecule bound to three molecules of FATTY ACIDS.

Based on the bonding of the carbon atoms in the chain, fats that contain chains with no double bonds are classified SATURATED FATS, while those that contain double bonds in the carbon chain are UNSATURATED FATS.

DNA undergoes the process of replication to produce new strands of identical DNA before cell divisions. Describe the basic dna replication. I will give you brainliest

Answers

Answer:

Please mark as Brainliest

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication

Step 1 Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be unzipped into two single strands

Step 2 Primer Binding. The leading strand is the simplest to replicate

Step 3 Elongation

Answer:

Each axis needs a scale to show the range of the data on that axis. The low end of the scale may be zero or a round number value slightly smaller than the smallest data point. The high end of the scale is usually a round number value slightly larger than the largest data point. The scale is measured off in major and minor tick marks. Typically the scale runs from low to high in easily counted multiples like 10s, 50s, 100s, etc. When graphs are compared side-by-side, consider scaling them to the same data range to make comparisons easier.

1. Greater than 0%

2. Greater than 5%

3. Double

Answers

Answer:

The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%

Explanation:

A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.

In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.        

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins

Answers

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

CNS controls eating by homeostatic mechanisms that interact  with different cognitive control systems (e.g., memory, reward, attention, etc)

Explanation:

In the brain, eating control is modulated by different systems:

1- Homeostatic control: the hypothalamus plays a key role by controlling both the appetite and food intake

2- Attention: the parietal and visual parietal cortices are involved in sensory perception and integration

3- Emotion and memory: amygdala and hippocampus

4-Cognitive control: the prefrontal cortex (i.e., executive functions)

5-Reward: associated with the functioning of the striatum

In the first place, external signals such as, for example, neurotransmitters and hormones, are received by the hypothalamus that interacts with different systems (reward, emotion, memory) in order to achieve a homeostatic control of eating. Neuronal stimulation (for example, when we view foods), is achieved by the supply of oxygenated hemoglobin.

Describe how a rainforest can reach a point when it cannot be restored by secondary ecological succession

Answers

Answer:Although the secondary forest will be low in diversity and poorly developed, the forest cover will be adequate for some species to return (assuming they still exist).  The solution must be based on what is feasible, not overly idealistic, and depends on developing a new conservation policy built on the principle of sustainable use and development of rainforests. Beyond the responsible development of rainforests, efforts to rehabilitate and restore degraded forest lands along with the establishment of protected areas are key to securing rainforests for the long-term benefits they can provide mankind.

Explanation:

i lloke dit up online because i have not did this yet

A very high damaged leads to no restoration of rainforest by secondary ecological succession.

A rainforest can reach a point when it cannot be restored by secondary ecological succession when the large portion of the rainforest is destroyed and most of diversity is vanished. At this time, restoration is impossible due to very high damages.

Ecological resilience is the ability of an ecosystem to be restored through secondary ecological succession after a severe disturbance. Rainforest have a high biodiversity that helps it to resist damage but at a certain limit so we can conclude that very high damaged leads to no restoration of rainforest by secondary ecological succession.

5. Ventricular filling.

6. Ventricular ejection.

7. Isovolumetric contraction.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole: in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The following terms describe the physical or mecahnical events with the correct phases of the cardiac cycle in mammals (human beings).

1. Isovolumetric relaxation: All 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.

2. Ventricular filling: The maximum amount of blood is in the ventricles at the end of this phase.

3. Isovolumetric contraction: The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.

4. Ventricular ejection: The semilunar valves are open and the AV valves are closed during this phase.

5. Ventricular filling: The atria contract at the end of this phase.

6. Ventricular ejection: The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.

7. Isovolumetric contraction: Systole begins with this phase.
