The surface's albedo of the incident light as a percent is determined as 30%.
What is surface's albedo?
The surface albedo quantifies the fraction of the sunlight reflected by the surface of the Earth.
The surface's albedo of the body is calculated as follows;
surface albedo = intensity of light reemitted / total intensity of light on the surface
As fractionsurface albedo = 3/10 = 0.3
As percentagesurface albedo = 0.3 x 100% = 30%
Thus, the surface's albedo of the incident light as a percent is determined as 30%.

Which observations led wallace to understand how species change over time? choose all the statements that apply
The observations which led Wallace to understand how species change over time are as follows:-
The traits in a population vary from one individual to another.Populations exhibit a tendency to produce more offspring in each generation than will survive.Individuals possessing traits which give them a slight advantage over other individuals in a population will survive, and over the period of time the former will surpass other individuals.Wallace did extensive fieldwork, firstly in the Amazon river basin and later in the Malay Archipelago, where he identified the faunal divide now know as the Wallace Line. The line divides the Indonesian archipelago into two distinct parts; a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia.

Following meiosis I, the daughter cells are ________; following meiosis II, the daughter cells are ________; and following fertilization and mitosis, the daughter cells are ________.
Following Meiosis I, the daughter cells are Haploid. Following Meiosis II, the daughter cells are Haploid and following Fertilization and Mitosis, the daughter cells are Diploid.
In a diploid cell containing a complete set of chromosomes and DNA content, After Meiosis I, the number of chromosome reduces by half thereby producing two daughter cells that are haploid which is termed as the Reductional Division due to the reduction in the number of chromosome and reduction of DNA content by half. Hence, the cell becomes Haploid after Meiosis I.
After Meiosis II, the number of chromosomes remains half as compared to the Diploid cell and only the DNA content reduces to one fourth as compared to the diploid cell. It is similar to Mitosis or Equational Division since no change occurs in the chromosome number as compared to the daughter cell obtained after Meiosis I. Hence, the cell remains Haploid after Meiosis II
After Fertilisation of two haploid cells formed after completion of Meiosis, the cell become Diploid (due to the fusion) containing complete set of chromosome and DNA content. After Mitosis of the newly formed Diploid cell, the number of Diploid cells increases due to the formation of two daughter cells produced continuously. No change in the chromosome number or DNA content occurs.

In the DNA isolation process, ice cold 95% ethanol is used to break down the protein complexes and allow the DNA molecules to easily precipitate.
What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis.Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix.The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light.The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution.The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: brainly.com/question/18316109

To identify people by dna, is it better to make copies of genes or non-coding segments? Explain.
To identify people by DNA it is better to make copies of non-coding segments because they exhibit more variation than genes.
The polymorphic sequences of non-coding DNA vary between individuals in humans. Variable number tandem repeats, or VNTRs, are created when DNA sequences are repeatedly replicated in the genome's non-coding regions. It is possible to create a person's genetic fingerprint by counting the amount of repeats, which varies between individuals. However, this non-coding DNA is used in criminal investigations by forensic experts.

Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks. what is the principle reason for this?
Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks because the extrusive magma cools quickly so the mineral grains do not have time to grow.
When lava comes out of a volcano and solidifies into extrusive igneous rock, the rock cools very quickly. Crystals inside solid volcanic rocks are small because they do not have much time to form until the rock cools all the way, which stops the crystal growth. Magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.

If it were possible to have antagonistic muscle pairs in an arm contract simultaneously, what movement would the arm make?
If it were possible to have antagonistic muscle pairs in an arms contract simultaneously, the arm would be locked in position.
How do antagonistic muscle pairs work?
Tendons allow muscles to exert force on bones. They pull on our bones and related body parts to move them; this activity is referred to as muscle contraction. In "antagonistic muscle pairs," muscles function. A pair of muscles work together to move a body part, and then the other muscle in the pair works together to bring the body part back to its starting position.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.

When dealing with Ecolabelling , it is important to educate consumers so that they do not fall victim to green washing/marketing schemes.
Ecolabelling (also "Eco-Labels") and Green Stickers are labelling systems for food and consumer products. The use of Eco labels is voluntary, whereas green stickers are mandated by law.
Some labels quantify pollution or energy consumption by way of index scores or units of measurement, while others assert compliance with a set of practices or minimum requirements for sustainability or reduction of harm to the environment. Many ecolabels are focused on minimising the negative ecological impacts of primary production or resource extraction in a given sector or commodity through a set of good practices that are captured in a sustainability standard. Through a verification process, usually referred to as "certification", a farm, forest, fishery, or mine can show that it complies with a standard and earn the right to sell its products as certified through the supply chain, often resulting in a consumer-facing ecolabel.
Ecolabelling systems exist for both food and consumer products. Both systems were started by non-governmental organizations (NGOs).
At least for food, the ecolabel is nearly identical with the common NGO definition of the rules for ecolabelling. Label trust is an issue for consumers because some manufacturers and manufacturing associations have set up "rubber stamp" labels to greenwash their products with fake ecolabels. High trust levels can be created when ecolabels apply for governmental recognition as formal Certification Marks (recognized by logos or names with 'CTM', CM or 'CertTM').
