Why do we need human dna

Answers

Answer 1

DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.

All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

We need human DNA since it give us the long term info storage, which is needed

Answer 2

DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.

What is human genome?

DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.

The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

A. cold winter, thin acidic soil, evergreen trees

B. many evergreen trees, short moist summers, long snowy winters

C. long cool summers, short dark winters, migrating animals

D. treeless, permafrost, cold dark winters

Answers

Answer:

D. treeless, permafrost, cold dark winters

Explanation:

The correct answer would be D

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.

What is a tundra?

The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.



Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.

Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.

Therefore, option (D) is correct.

32. Briefly describe how sedimentary rocks form. How do both of the two main subcategories form?


33. Briefly describe how metamorphic rocks form. How do both of the two main subcategories form?

Answers

Answer: 31, Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground

32, Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals

33, Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.

d. a light year unit is very large and distances in space are very large

Answers

Answer:

i am not sure but i think is D

A light year unit is very large and distances in space are very large. So, the correct option is D.

What is Light year?

A light year is defined as the larger unit of length which is used to express astronomical distances and is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.

A light-year is expressed as the distance that light travels in a vacuum in one Julian year, which is 365.25 days because it includes the term "year", the term light-year is sometimes misunderstood as a unit of time.

1 light-year   = 9460730472580800 metres

Light year is used as a unit to express distances to celestial objects, for example, if a star is 4 ly away from earth, it means that light from the star will take 4 earth years to reach us.

Therefore, a light year unit is very large and distances in space are very large. So, the correct option is D.

C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.

Answers

Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to  use

When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.

Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).

When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.

Tickleback evolution lab final quiz 1. how did some ancestral sea-run stickleback populations come to live exclusively in fresh water? these populations swam to freshwater lakes to spawn and then never returned to the ocean because there were fewer predators in lakes. they became trapped in lakes that formed at the end of the last ice age. they don't actually live exclusively in fresh water; they only live in fresh water at certain stages in their lives. they developed traits that made them better adapted to fresh water and, as a result, had to move to a freshwater environment to survive.

Answers

Answer:

The correct answer is "some stickleback populations come to live exclusively in fresh water they became trapped in lakes that formed at the end of the last ice age".

Explanation:

There are different types of speciation. Allopatric speciation consists of the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations. Some barriers might impede the genetic interchange or genetic flux, making a place to two new populations that are separated and can not get together to mate anymore. Glaciation is one of the most important drivers of speciation and production of different phylogeographic structures by vicariance. Glacials originate isolated gene-pools that accumulate differences that end in reproductive isolation. Melting of the ice also generated divergence and speciation, as land appearance acted as a barrier for some populations.  

During the last glaciation, stickleback fishes were able to reach certain new places or areas that provided better conditions to inhabit. There were fewer predators and more available food sources that made these new areas to be a better choice. These new grounds were lakes and were the product of ice melting. But at a certain point, as ice melting increased, the land started to show up again and became a barrier for this species. Animals that were living in lakes could not go back to the sea, they were trapped so they had to adapt to living exclusively in lakes. This species diverged and suffered speciation.

The orbital speed of the galaxies in the cluster is fast enough to keep the cluster intact.

Answers

Answer:

1. T^2=r^3 ( or T² = r³)

2. "The exposed water reflects back more sunlight than did the ice"

and

"The exposed water absorbs more thermal energy from the sun than did the ice'

3. Dark matter provides the mass and gravity needed to keep the cluster together.

Explanation:

1. Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?

Kepler's Third law of planetary motion is the ratio of the square of the orbital period of a planet is to the radius of orbit of a planet or those of other planets.

This means that, Kepler's Third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

Mathematically, Kepler's Third last is represented as

T² : r³

= T² = r³

Therefore, the second option,T^2=r^3 which is equivalent to T² = r³ is the correct option

2. Which of the following are effects of melting sea ice? Select the two correct answers.

The melting of sea ice causes a lot of changes in the climate of an environment.

The presence of sea ice in oceans, reduces the surface area thereby causing a minimal reflection of sunlight but once sea ice melts, the surface area of the water is increased and this would results in a reflection of sunlight.

The sea ice absorbs less thermal energy or radiation from the sun(solar energy) and keeps the surface cooler but once the sea ice is melts, the resulting water, absorbs a lot of thermal energy or radiation from the sun, causing the surface of the water to be hot.

Therefore, the options "The exposed water reflects back more sunlight than did the ice" and

"The exposed water absorbs more thermal energy from the sun than did the ice" are the correct options.

3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?

It has been observed that galaxies present in the solar system have an attraction for one another such that they are drawn to each by force of gravity that is present in the solar system. And because of these, galaxies form clusters in the solar system.

Dark matter is a large amount of matter that is present in the solar system. Dark matter is the reason by which galaxies can form and maintain the clusters that they form around each other because it provides them with the force of gravity and sufficient mass that the galaxies require to prevent them from separating or flying away(apart) from one another

Therefore, the option "Dark matter provides the mass and gravity needed to keep the cluster together" is correct.

The simplified version of Kepler’s third law in a situation when one of the planets is compared to Earth will be T³ = T².

The effects of melting sea ice include:

The exposed water reflects back more sunlight than did the ice.The exposed water absorbs more thermal energy from the sun than did the ice.

A cluster will remain intact because the dark matter provides the mass and gravity needed to keep the cluster together.

It should be noted that Kepler's third law of planetary motion simply represents the ratio of the square of the orbital period of a planet is to the radius of orbit of other planets. This can be expressed mathematically as T³ = T².

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?

Answers

Answer:

40% increase

Explanation:

Percentage Increase Formula:

Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%

To Calculate Percentage Increase:

   1) Subtract final value (later value) minus starting value (initial value)

  2) Divide that amount by the absolute value of the starting value (initial value)

  3) Multiply by 100 to get percent increase

Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.

So for your problem,

[(420-300)/300]*100% = 40% increase
