DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.

Answer:

Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path.  Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

There is no single attitude to contraception within Islam; however eight of the nine classic schools of Islamic law permit it. But more conservative Islamic leaders have openly campaigned against the use of condoms or other birth control methods, thus making population planning in many countries ineffective.

Answer:

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.

Explanation:

The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.  

The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.

The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.

Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

Answer:

Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.

Explanation:

Explanation:

Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.

By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

Answer:

bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.

Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.

fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.

Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.

Answer:

5 Facts

Explanation:

1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.

2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.

3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.

4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.

5.  Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
