Answer:

Electric vehicles (EVs) offer an opportunity to replace fossil fuels in the transport sector. Electrification of the transport sector can also bring benefits in terms of increased energy efficiency and reduced local pollution. However, there are genuine concerns about meeting the future energy demand for charging EV batteries with clean and renewable sources. More importantly, the issue of long-term sustainability of EVs is underscored by the supply risks of critical material resources used in the EV batteries. Extraction of some of these material resources are linked to significant environmental impacts as well as social and ethical issues.

Explanation:

General category: Biology.

Sub-category: Ecology

Topic: Natural resources

Introduction:

The term sustainability describes how biological systems remain diverse and productive over time.

Sustainability refers to how biological systems remain productive over time. In particular, the term sustainability is described as the balance of a species with its resources in its specific environment. On the other hand, sustainable development is exercising the correct use of current resources without compromising those of future generations. Therefore, sustainable processes preserve, protect and conserve current and future natural resources.

We can conclude that the correct answer is:

Sustainability refers to how biological systems remain productive over time. In particular, the term sustainability is described as the balance of a species with its resources in its specific environment.

The result of the following cross indicates that orange eyes would be recessive to black eyes.

According to Mendel, a cross between two people who are heterozygous for a dominant trait would result in offspring with a 3:1 phenotypic ratio, with the dominant trait making up around 75% of the phenotype and the recessive trait making up the remaining 25%.

The black eye color phenotype in this instance is 247, whereas the orange eye color phenotype is 86.

Calculating each trait's proportion

247/333 ×100%, or 74.1%, are black eyes.

Orange eye: (86/333 x 100%) = 25.8%

74.1:25.8 is approximately 3:1

It follows that black eyes are dominant and orange eyes are recessive.

Biomes are large areas characterized by its soil, climate, vegetacion, and wildlife. There are five major types of biomes: grassland, florest, tundra, desert, and aquatic, they still can be divided into more specific categories, such as marine (aquatic), rainflorest (florest), savanna (grassland/desert), and others. The diversity of these biomes can be based in the animails and plants of the biome, diverse biomes have a wide variety of species and are considered more livable with less environment pressure and challenges that make the area more conducive to higher diversity. The Topical florests are widely considered to have the greatest species diversity of the terrestrial biomes, with nice climate and food for the wildlife. The non-diverse biomes have extreme conditions that make them have lower diversity, for example, tundra and deserts have low diversity because of the climate and the condictions of soil and water.

Answer:

Magnetic.

Explanation:

Electric energy is the energy caused by the movement of the electric charges. The moving electric charges form the kinetic energy, thus electrical is the from of energy.

Thermal energy is the energy which usually comes from the heat.This heat is generated by the movement of tiny particles within an object. Thus, thermal energy is the form of energy.

Nuclear energy is the energy which comes from the splitting atoms in a reactor to heat water into steam and generate electricity. Thus, nuclear energy is the form of energy.

The magnets cannot be used to generate energy, as it is kind of a force which attracts a body from the another body, therefore the magnetic is not the form of energy.

Mutualism is a type of relationship exists in microbiomes between bacteria and humans.

Option C is correct.

The human intestine and many of its symbionts have a mutually beneficial relationship in which the intestine supplies nutrients to the resident bacteria while the bacteria help with food digestion and nutrient absorption, produce vitamins like biotin and vitamin K, and control immune system activity.

Individual variations in the microbiome influence host health, may be implicated in disease genesis, and affect drug metabolism, toxicity, and efficacy. Humans have established intimate symbiotic connections with a consortium of gut bacteria (microbiome).

Ead-25 genotype that were observed in one or more daughter cells was also present in the parental cell.

EAD- 6 genotype were ONLY in the daughter cell.

An organism's genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism's allelic combination.

Moreover, genotype, the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individual's genotype comprises the entire complex of genes inherited from both parents.

Hence, alleles of the same gene are either autosomal dominant or recessive. An autosomal dominant allele will always be preferentially expressed over a recessive allele. The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.
