Conventional fossil fuels are harmful to the environment. Alternative solutions include using nuclear energy or solar energy. A

decision to opt for solar power over nuclear energy might be based on which of these facts?
Biology

Anna11 [10]3 years ago

Explanation:

Nuclear energy is created by the process of splitting atoms such as uranium atoms into smaller and lighter atoms and thereby converting the "lost" mass into heat. This lost mass is consequently used in production of electricity.

Solar Energy generation on the other hand is achieved by converting the radiation of the sun via solar panels and cells to electric current.

The disadvantages of nuclear energy over solar energy include the following :

a. SECURITY MATTERS : People who do not have very healthy intentions can easily target nuclear plants with the sole purpose of causing problems while uranium ( the chief ingredient for nuclear power generation) can be converted to nuclear weapons if the wrong people come in contact with it. This disadvantage obviously doesn't apply to solar energy generation

b. ACCIDENT: Nuclear energy isn't as safe as solar energy.

c. THE IMPACT ON THE ENVIRONMENT: Enrichment and mining of uranium are not processes that one can consider friendly to our environment. Open mining for uranium constitutes radioactive particles which can cause erosion and pollute water bodies or sources. This is not the case in solar power generation.

Answer: solar energy is renewable and less radioactive

Explanation: The fact that solar energy is renewable and less radioactive gives it an edge over nuclear energy. Nuclear energy is generated from fission of nuclear elements which are rare and are not readily available.

Which of the two seal groups, earless seals or fur seals, can move rapidly on land? why?
densk [106]

Answer:Flippered and charismatic, pinnipeds (which includes seals, sea lions, and walruses) are true personalities of the sea. Like whales, manatees, and sea otters, they are marine mammals, meaning millions of years ago their ancestors evolved from a life on land to a life at sea. Today, they remain creatures of both land and sea. Though able to walk on land, they are truly at home in the water. Strong flippers and tails propel them and a streamlined body helps them cut through the water efficiently.

It’s easy to tell the enormous, tusked walrus from other pinnipeds, but seals and sea lions are easy to confuse. The easiest way is to look at their ears—sea lions have small ear flaps while seal ears are nothing but small holes.

Once sperm cells are mature and capable of fertilizing an egg they are stored for delivery in this part of the male reproductive
telo118 [61]
The answer is epididymis.
Epididymis is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the ale reproductive system. Sperms matures as they pass through the epididymis so that they are ready to fertilize ova by the time they enter the ductus deferens.  During the ejaculation stage of emission sperms are moved from the testes and the epididymis, where they are stored, to the beginning of urethra.

Short segments of newly synthesized DNA are joined into a continuous strand by _____.Short segments of newly synthesized DNA are
Sloan [31]

Answer:

a. Ligase

b. Ligase ( it's repeated)

Explanation:

DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.

Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.

lbvjy [14]

Answer:

The 5 impacts humans have on the environment in order from easiest to fix to hardest to fix is explained below in details.

Explanation:

Humans impact the physical surroundings in various forms: pollution, smoking fossil fuels, overpopulation, including deforestation. Developments like these have triggered climate modification, soil erosion, poor air quality, and impure water.

The Biggest Environmental Problems

  • Biodiversity Decline.
  • Plastic Pollution.
  • Deforestation.
  • Air Pollution.
  • Agriculture.
