Annette [7]3 years ago
8 0

we have 4 different bases: Adenine(A) thymine(T) cytosine(C) and guanine(G)

We have combinations 32 taken 4

written as 32C4=32!/4!(32-4)!=32!/4!*28!=29*30*31*32/24=35960

The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of
9966 [12]

Answer:

The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of <u>molecules moving a little farther apart.</u>

Explanation:

The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.

What are the advantages and disadvantages of using renewable and nonrenewable energy resources? Use evidence from the lesson and
timofeeve [1]

Answer:

The answer to this question is given below in this explanation section.

Advantages of renewable energy resources:

Using renewable energy over fossil fuels has a number of advantages.Here are some of the top benefits of growing green.

  • Renewable energy won't run out:

Renewable energy technologies use resource straight from the environment to generate power.These energy sources include sunshine,wind,tides,and biomass,to name some of the more popular options.

  • Maintenance requirements are lower:

In most cases,renewable energy technologies require less overall maintenance  than generators that use traditional fuel sources.This is because generating technology like solar panels and wind.

  • Renewables save money:

Using renewable energy can help you save money long term.Not only will you save on maintenance costs,but on operating cost as well.When you are using a technology but generates power from from the sun wind team natural processes.

  • Renewable energy has numerous health and environmental benefits:

Renewable energy resources emit little to no greenhouse gases or pollutants into the air.

  • Renewable lower reliance on foreign energy sources:

With renewable energy technologies you can produce energy locally.The more renewable energy you are using for power needs.

Disadvantages of renewable energy:

  • Higher upfront cost:

You can save money by using renewable energy the technologies are typically more expensive upfront by traditional energy generators.

  • Intermittency:

Through renewable energy resources are available around the world many of these resources are not available year around.

  • Storage capabilities:

Because  of this intermittency of some renewable energy resources there a high need of energy storage.

  • Geographic limitations:

The united states has a diverse geography with varying climates topographies vegetations and more.

Describe how the three major types of deserts differ in their climate and vegetation. How do plants and animals survive?
egoroff_w [7]

Answer:

a)

1. Tropical deserts: Hot and dry most of the year; They have a few plants and a hard, windblown surface strewn with rocks and some sand.

2. Temperate deserts: Hot in the summer and cold in the winter; There is more precipitation than tropical deserts; The sparse vegetation primarily consists of widely dispersed, drought-resistant shrubs and cacti or other succulents adapted to the lack of water and temperature variations.

3. Cold deserts: Winters are cold, summers are warm or hot, and precipitation is low; Desert plants and animals have adaptations that help them to stay cool and to get enough water to survive.

b)

Plants and animals survive because They have adaptations that help them to stay cool and to get enough water to survive
