The crust? Hope that helps
Answer:
D.) Rocky
Explanation:
The crust is the top layer of the Earth which is relatively thin in comparison to other layers. The upper layer of Earth is called lithosphere.
The crust is composed of variety of rocks such as metamorphic, igneous, and sedimentary rocks. Below the crust, is the mantle which is also composed of rocks but also have semi-solid magma.
Hence, the correct answer is "D.) Rocky".
In order to attain stability, the elements such as carbon and hydrogen need <em>4 and 7 electrons</em> respectively.
As the elements such as carbon and hydrogen are in need of electrons, they are called anions (the electron gaining substances) and they gain required electron from <em>the cations,</em> the substance which readily losses electrons.
As far as carbon is concerned, as it can readily accept four electron, it need <em>four atoms</em> of cations.
Se crean nuevas células a partir de un proceso llamado división celular. Las nuevas células se producen cuando una célula, llamada célula madre, se divide en nuevas células llamadas células hijas.
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.
