a scientist claimed that he cloned a guinea pig to produce 2 offspring a male and female. the claim is not valid why

Answers

Answer 1
Answer: The claim is not valid because the clone can only be one gender. For instance, let's say the original guinea pig was male. The only way that the guinea pig offsprings are its clones is when the genetic data are IDENTICAL. It obviously isn't identical when there are two different genders.

Territorial animals like spiders that fight off intruders would be expected to be ?

Answers

Correct answer: Regularly distributed

The territorial animals like spiders are expected to regularly distributed. It is the way by which they could keep their territory because if they clustered together then it might that they all get killed at once and may lose territory. So, to prevent this they are regularly distributed and are able to fight predators and intruders and keep their territory safe.

Denzel's mom has asked him to organize the family's trash for disposal. Which of these items should he put with the hazardous waste?a. aluminum cans
b. Used batteries
c. vegetable waste

Answers

The answer would be used batteries. You would be able to recycle the vegetable waste within fertilizing and/or throw it away safely by disposing it in a trashcan since it is not a hazard towards the environment. As for aluminum cans, they are recyclable and are easy to use again once it is filtered through the system. However, batteries are NOT recyclable nor easy to dispose because they can release Alkaline which can harm the environment.

The correct answer is option B

The trash that can be harmful for the people should disposed off in the hazardous waste.

The used batteries should be dumped into it as it can be hazardous if it is exposed to the heat and pressure.

There can a minute explosion caused due to used battery if it is not kept safe in the receptacles. This waste cannot be recycled and reused.

What are some of the processes involved in the flow of matter andenergy among Earth's geosphere, hydrosphere, atmosphere, and


biosphere?

Answers

Answer:

The flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere involves several processes. Some of these processes include:

1. The water cycle: Water evaporates from the hydrosphere into the atmosphere, forms clouds, and then precipitates back to the Earth's surface. This process helps in the transfer of water and energy between the hydrosphere and atmosphere.

2. Nutrient cycling: Nutrients like carbon, nitrogen, and phosphorus move through the biosphere through processes like photosynthesis, respiration, decomposition, and nutrient uptake by plants. These cycles help in the transfer of matter and energy between the biosphere and geosphere.

3. Energy transfer: Solar energy is absorbed by the Earth's surface, leading to heating of the geosphere. This heat is then transferred to the atmosphere through processes like conduction, convection, and radiation. The biosphere also relies on this energy for photosynthesis and other metabolic processes.

4. Geological processes: The geosphere plays a role in the cycling of matter and energy through processes like weathering, erosion, and volcanic activity. These processes can release or store nutrients and gases, affecting the hydrosphere, atmosphere, and biosphere.

These are just a few examples of the interconnected processes that contribute to the flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere.
