How does the stratigraphic principle help us determine the age of layers of rocks?

Answers

Answer 1

Answer:

The principles of stratigraphy help us understand the relative age of rock layers. Layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontal). Younger layers are deposited on top of older layers (principle of superposition). Layers that cut across other layers are younger than the layers they cut through (principle of cross-cutting relationships). The principle of superposition builds on the principle of original horizontal. The principle of superposition states that in an unreformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it. Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.

A two-word name for organisms where the first word is the species and the second word is the genus

Answers

Answer:

A two-word name for organisms where the word is the genus and the second word is the species

Explanation:

Binomial nomenclature is the system biologists use to name species of living beings. When we translate this term, we get the two-name naming system. This tells us a lot about how species are named - their name consists of two components. The first component is the name of the genus the species belongs to and the second is the name of the species. For example, the scientific name used for cats is Felis catus. Felis is the genus and the species is catus.

RNA interference (RNAI) is a mechanism of gene regulation in eukaryotes. RNAI is initiated by ____, which leads to the ____ of specific genes.
Box 1:
single-stranded RNA
double-stranded RNA
double-stranded DNA
Box 2:
silencing
induction
expression

Answers

Answer:

double-stranded RNA;  silencing

Explanation:

The RNAi mechanism is a natural process of gene silencing triggered by different small non-coding RNAs such as, for example, siRNAs, miRNAs and piRNAs. RNAi is a powerful technique to induce gene silencing in a sequence-specific manner. The delivery of exogenous double-stranded RNAs (dsRNAs) can be used to induce this evolutionarily conserved mechanism.  The dsRNAs first bind to RNAi core components (Ago, Piwi proteins) and then target complementary mRNAs to induce their degradation.

it is structural and functional unit of living beings

it includes all the activities of cells

it is there in each and every life process

Explanation:The cell is called the structural and functional unit of life as all living organisms are made up of cells. ... Furthermore, cells provide form and structure, process nutrients and convert it into useable energy. Multicellular organisms have specialized cells that perform specific functions.

Please help me in my homework (keep it simple,i couldnt find Science ;-; I am sorry) What is environment? What are three main aspect of environment? 2)Write down any four importance of environment.

Answers

Answer: It is then the space in which the life of living beings and the interaction between them and other things takes place. It is made up of living organisms, abiotic elements and artificial elements. It includes physical, chemical and biological components of the organisms and elements that form it. It is important because it is the place of habitat of humanity, it provides natural elements such as water and food, it provides fuels and raw materials that serve to manufacture artificial things and it contributes to the sustainability of life on the planet.

Explanation:

The environment is a system made up of living organisms (such as animal and plants), abiotic elements (lifeless, such as stones or water) and artificial elements (created by man, such as buildings) that are related to each other and can be modified by human action. It is then the space in which the life of living beings and the interaction between them takes place.

It includes physical, chemical and biological components of the organisms and elements that form it. That is, how is its composition and its function in the environment.

The importance of the environment lies in:

It is the place of habitat of humanity, so it influences the life of human beings and future generations. It is the space where life develops at this time with all living beings and their natural components.It provides natural elements such as water and food since it offers all its natural resources needed by the human being. It provides fuels and raw materials that serve to manufacture the artificial things we use daily, to build houses, have light, transport, among many other benefits to exist. In the environment we find a great biological diversity of plants and animals that help maintain the ecological balance of the earth. This contributes directly to the sustainability of life on the planet. Each organism has a unique role to play.

Therefore, all societies must guarantee their care for their existence and make rational use of all their resources.

Explanation:

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.

What is Codons?

The anticodon is the complementary three nucleotide sequence in the appropriate tRNA. Template stand is the DNA strand off which the mRNA is synthesized.

Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein synthesis (stop signals). There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.

The bases that make up DNA and the associated messenger RNA are called bases. These nucleotides are frequently identified in RNA by the letters A, U, C, and G.

Therefore, The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.

In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BBFF x bbff cross would be expected to be heterozygous for both traits?

Answers

Answer:

100%

Explanation:

This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).

In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:

BBFF - BF, BF, BF, and BF

bbff - bf, bf, bf, bf

Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?

Answers

Answer:

Three different genotypes and two different  colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b).

If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb.

BB - black offspringBb - black offspringbb - white offspring

Therefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).
