Identy three advantages and three disadvantages of bioplastics

Answers

Explanation:

Advantages of bioplastics

1.Less oil is used to produce petrochemical (oil-based) plastics which pose a great risk to the environment.

2.The common bioplastics can be injection molded and shaped to take the same form as traditional thermoplastics. In some cases, the bioplastics are stronger and lighter, too, so they are not necessarily only suitable for very niche applications.

3.Bioplastics are more marketable, for example, their usage may improve the value-add of a product through a green marketing campaign. After all, studies have shown that ‘80% of European customers want to buy products with a minimal impact on the environment,’ so bioplastics may represent a useful argument for brands.

Disadvantages of bioplastics

1.First, bioplastics are generally NOT cost-competitive compared to their oil-based counterparts. They are generally two or three times more expensive than the major conventional plastics such as PE or PET, and their production is plagued by low yields and being expensive. This disadvantage should be less acute when manufacturing plants become larger and benefit from economies of scale. A good example is Braskem’s 200,000-tonne bio polyethylene plant (equivalent to about 20% of the world’s current bioplastics production).

2.There is a concern that bioplastics based on terrestrial crops could harm food supplies; however, new innovations using food waste could be helpful in this regard and the concerns would seem to be unfounded as: ‘Perhaps 300,000 hectares are used to grow the crops which the industry processes into plastics. For comparison, this is about 0.02% of the world’s total naturally irrigated area available for cultivation. Even if half the world’s plastics were made from crops grown on food land, the industry would only require 3% of the world’s cultivated acreage.’

3.Crop-based bioplastics require fertile land, water, fertilizers, and are reliant on weather conditions. This means that the supply of raw materials for bioplastics are at risk of natural phenomena, such as drought.

Answer:

Three advantages of bioplastics:

1. Saving fossil fule

2. Reduction of greenhouse gas emission

3. Reclamation of by-products

Three disadvantages of bioplastics:

1. It won't biodegrade in a landfill

2. It contaminate plastic recycling streams

3. It encourage people to litter more

The Kirkwood gap is an asteroid belt region situated between the orbits of Mars and Jupiter that has a significant depletion of asteroids. This chasm is caused by Jupiter's gravitational pull, which causes asteroids to move around and destabilase their orbits.

What is Kirkwood gap?

The Kirkwood gap is an asteroid belt region located between the planetary orbits of Mars and Jupiter that has a significant depletion of asteroids. This chasm is caused by Jupiter's gravitational pull, which causes asteroids to migrate and destabilize their orbits.

Jupiter's gravity has a major influence on the asteroid belt, causing their orbits to grow unstable and potentially crash with other objects. As a result, asteroids in some asteroid belt regions may be expelled from their orbits or smash with other things, leaving gaps or areas with fewer asteroids.

The Kirkwood gap was named after the American scientist Daniel Kirkwood, who first observed the decrease of asteroids in this region in the year 2000.

Therefore, the Kirkwood gap is an asteroid belt region situated between the orbits of Mars and Jupiter that has a significant depletion of asteroids.

una persona camina durante una hora y media y corre 4 km con velocidad constante ¿cuál era su velocidad en km/h y en m/s?​

Answers

La respuesta es: su velocidad es 2.66 km/h, equivalente a 0.738 m/s.

Explanation

Para conocer la velocidad de una persona que recorrió 4 km luego de caminar durante una hora y media es necesario dividir la distancia (en kilómetros) total en el tiempo (en horas). Entonces la operación sería:

4km/1,5h = 2.66 km/h.

Posteriormente, para convertir 2.66 km/h en m/s es necesario aplicar la siguiente formula

2.66 km/h *(1000 m/1 km)*(1 h/3.600 s) = 0.738 m/s.

C. neutral, positive

D. neutral, negative

Answers

Answer:

option c

Explanation:

The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.

What is polarity?

The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.

Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.

The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.

Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

What does the word Photosynthesis mean?

C. Taking apart with light.
D. Putting together with light.

Answers

Answer:

A

Explanation:

release of energy through the breakdown of glucose

The release of energy through the breakdown of Glucose means Photosynthesis.

Photosynthesis

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs  "light", and synthesis  "putting together" Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas.

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20

Answers

Explanation:

Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.

In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.

In human cells, the mutation rate is approximately 10⁻⁴ per generation.

Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).  

In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population

Answers

Answer:

The correct answer is - 0.20

Explanation:

According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.

It helps us to predict the genotype frequencies in a large population.  If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1

p2+2pq+q2=1

The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.
