It would be c.
Gravity force on earth: 9.8N or m/s estimed to 10N
818/10= 81.8 kg on earth
form the equation:
81.8×x=5320
If we solve this equation we will get an answer near 63.7 m/s.
Answer:
D. People allow only organisms with certain traits to reproduce.
Answers:
- The sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function.
- The sequence is contained in a retrovirus that has infected both species.
1- Explanation:
6.8 million years is a considerable period of time and if the cats were evolved in two different specie then technically they should have substantially different sequences of gene. However, there are some genes that are critical for the survival of the organisms because they encode a function which is equally important for the organisms of a certain category, even if they are different specie.
For example, the essential genes that are involved in maintenance of metabolism, initiation of replication or translation of genes. Therefore, with the period of time, the mutation of even a single nucleotide can be lethal for these genes, and if it happens organism will simply die. So, if one organisms is died that cannot take part in the process of evolution and would clearly be cut off from the process, However, those who survive can undergo some other mutations and become separate specie.
2- Explanation:
A retro virus inserts itself in to the genome of host organisms and become a part of them. It is very difficult to detect the presence of the retro virus until the organism undergoes infection due to its attack. Cats are a favorable host for retroviruses - called lentiviruses which attack the cats to cause a critical syndrome Feline Immunodeficiency Virus or FIV. Therefore, it is possible that same retrovirus having a particular sequence has attacked both cats and the sequences were taken from those cats.
Hope it help!
The puzzle shapes also helped them understand his theory, so did tectonic plates, I gave you all I know! I wish I could help more but I haven’t learned this stuff in years! I’m sorry! Anyways hope you find out!
The polar jet stream expresses seasonal change. <em>The change in the </em><em>polar jet stream</em><em> from summer to winter position causes </em><em>cooler temperatures</em><em> farther south and causes </em><em> storms</em><em> to move more rapidly. Option 4.</em>
<h3 /><h3>Jet Streams</h3>
- A jet stream is a strong and narrow air stream concentrated along the horizontal axis in the troposphere.
- The stream wide is about 200 km, and its thickness ranges between 5,000 and 7,000 m.
- The strongest winds are in the central region of the stream, known as the jet core, with a speed of about 120 km/hour.
<h3>Types</h3><h3 />
- There are five jet stream types.
- Two polar streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
- Two subtropical streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
Both of them are west streams. And the polar ones are stronger than the subtropical ones.
- The tropical stream that comes from the east.
<h3 /><h3>Polar Jet Stream</h3><h3 />
- In the northern hemisphere, the polar jet stream affects mainly the Iberian peninsula.
- It gets formed in the convergence region, where the cooler winds from the Pole and the warmer winds from the Equator meet.
- This stream surrounds the Earth making several waves on its course.
- It occurs a seasonal balance between the winter and summer
→ Winter ⇒ The polar jet stream places between 35 and 40º latitude.
→ Summer ⇒ The polar jet stream is placed at about 50º latitude.
Following this seasonal change, from summer to winter cooler air masses reach lower latitudes and might be the cause of severe winter storms.
According to this framework, we can assume that <em>the </em><em>change</em><em> in the </em><em>polar front jet stream</em><em> from summer position to winter position causes </em><em>cooler temperatures</em><em> farther </em><em>south </em><em>and causes </em><em>storms</em><em> to move more rapidly. </em>
The correct option is (4).
