can someone plzz help me on this question its hard :( and i want to pass

Answer:

Epistasis effect result into these offspring

Explanation:

Given

spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b)

Genotype of true-breeding black spotted rabbit BBSS

Genotype of  true-breeding brown solid rabbit bbss

Genotype of offspring BbSs

In normal crossing between BbSs and BbSs offspring of F1, should produce offspring in the ratio 9:3:3:1

But it does not happens in this case the simple reason could be  presence of Epistasis in which the alleles assort independently but do not express themselves because of the following reasons -

a) Interaction between two or more loci thereby resulting into new phenotypes

b) An allele at one locus masks effects of other allele at one or more loci

c) Allele at one locus modifies the effects of alleles at one or more other loci

Answer:

Autosomal Recessive

Explanation:

The method of inheritance is autosomal recessive. Notice how the disease skips the parent generation. This indicates that parents have the recessive allele but do not express the trait. The individuals who are shaded in have two recessive alleles that were passed on from their parents, therefore they have the disorder.

Explanation:

DNA attributes to the genotype preference to the individual.  DNA contains the instructions for building RNA, which influences traits. The correct statement is answer A.

DNA stands for deoxyribonucleic acid.

DNA contains the orders that are needed for any organism in order  to develop, survive as well as reproduce. To carry out these duties, DNA sequences are needed to be converted into messages which can be used to produce proteins in  which are the complex molecules that are  doing  most of work in our body.

Since we have two pairs of chromosomes and we also have two pairs of genes in which  one  is from our father and one is  from mother. These pairs of genes then determine certain physical features or traits.

Answer: The answer is the following.

the question is: sound waves move through which medium?

a. water

b. ice

c. air

d. wood

the best answer to this question would be c. air. <3

Explanation:

The Speed of Sound: Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Air is a gas so therefore, C. AIR IS THE CORRECT ANSWER :)

The sound waves move the slowest through which medium:

C.Air

Therefore, the correct option is C.

Answer:

When Organism A has a trait that negatively impacts it, or lacks a trait which would positively impact it, then said organism perishes, and its genes are not passed onto the next generation. On the flip side, when Organism B has a trait that positively impacts it, or lacks a trait that would negatively impact it, then the organism thrives, and its genes are passed onto the next generation.

Therefore, the next generation receives genes from Organism B and does not receive genes from Organism A. So, the next generation has traits that positively impact it and lacks traits that would negatively impact it, thus evolving according to Darwin.

What was explained by it? Evolution. But how did it explain evolution? That is in the answer.

Answer:

Tiktaalik roseae

Explanation:

The discovery of the fossil, Tiktaalik roseae on a Canadian island gives credence to the fact that animals moved from living in water to living on dry land. This fish which has feature of land animals such as a neck, skull, and ribs is believed to have lived some 375 million years ago. It also has features of fish such as the fins and scales.

The discovery of this fossil is important to scientists because it confirmed their believe that there should be an organism that would prove that life transitioned from water to land. The fossil was discovered in the year 2004.

Answer:

Agriculture consumes more water than any other source and wastes much of that through inefficiencies. Climate change is altering patterns of weather and water around the world, causing shortages and droughts in some areas and floods in others. At the current consumption rate, this situation will only get worse.

Answer:  Identify the promoter and the stop signal (terminator).

Explanation:

DNA is a molecule that contains the genetic information in all living things. This information is used for the synthesis of proteins that make up the body and carry out vital functions of the organism.

The DNA molecule consists of two strands that wind around each other to form a double helix structure, where each strand has a central part formed by sugars (deoxyribose in the case of DNA) and phosphate groups. The four basic components of DNA are nucleotides: adenine (A), thymine (T), guanine (G) and cytosine (C). The nucleotides are joined together (A to T and G to C) by chemical bonds and form base pairs that connect the two strands of DNA. Depending on the sequence of nucleotides (which have different bases), different proteins are synthesized.

DNA replication consists of synthesizing another identical DNA molecule, using enzymes called polymerases, which are molecules specifically dedicated only to copy DNA. Transcription, on the other hand, is the process by which a copy of messenger RNA (mRNA) is generated from the sequence of a gene in the DNA. This RNA molecule leaves the cell nucleus and enters the cytoplasm, where it directs protein synthesis (a polymer made up of many amino acids).

Protein synthesis, or translation, involves translating the sequence of an mRNA molecule into an amino acid sequence during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding sequence of amino acids it encodes. To begin translation, a start codon (set of 3 bases) must first be identified, which is usually AUG that also codes for the amino acid methionine. Then, the codons that follow are read and the corresponding amino acids are added according to the genetic code. The transfer RNA (tRNA) is complementary to the anticodon at specific codons in the messenger RNA and carries the amino acid coding for the codon. In addition, ribosomal RNA (rRNA) is an RNA that is part of ribosomes and is essential for protein synthesis in all living things. rRNAs form the framework of ribosomes and associate with specific proteins to form ribosomal pre-subunits. To finish the translation, a termination codon has to be read, which can be UGA, UAG or UAA.

To revise the model to show transcription to form mRNA, the research should identify the promoter and the stop signal. The promoter is a DNA sequence required to turn a gene on or off. The transcription process starts at the promoter which is usually located near the beginning of a gene and has a binding site for the enzyme that is used to make a messenger RNA (mRNA) molecule. The enzyme RNA polymerase will keep doing the transcription until it reaches a sequence of DNA that is signal which indicates it should stop. This process is called termination, and it happens once the enzyme reaches this sequence, called terminator.
