1. Which option orders the events chronologically, from earliest to latest.
Answer: Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.
2. Which forms of life were dominant in the Mesozoic era?
Answer: Reptiles
3. How did the success of photosynthetic bacteria change Earth’s atmosphere?
Answer: increased oxygen concentration
4. How did reduced methane concentrations in the atmosphere affect Earth?
Answer: Earth cooled.
5. Which characteristic defines the Paleozoic era?
Answer: Animals with shells and hard parts were dominant for the first time.
You're welcome.
Answer:
Earth cooled.
Explanation:
The reduced methane concentrations in the atmosphere affect Earth :
Particles of gas and dust released into the atmosphere during a volcanic eruption affect the climate. Most of the particles emitted by the volcano cool the planet by blocking incoming solar radiation. The cooling effect can last from months to years, depending on the nature of the eruption.Therefore, the Earth is cooled.

Epistasis is observed when the allele of one gene masks the effects of another gene. Use the Punnett square to answer the question.
What color would a dog's fur be if its genes are aabb? (10 points)
A. yellow
B. brown
C. black
D. white
Answer:
The color of a dog's fur with the genes aabb would be yellow. So, in other words, Option A is correct.
Hope this helped :D Happy holidays! :D
Epistasis is the effect or character appear due to the interaction between genes. Here, the alleles responsible for the color of dog's fur show epistasis and the progeny with (aabb) genotype will show white colored fur. Thus, the correct option is D.
What is Epistasis?
Epistasis is also known as gene masking, where the expression of one gene is modified or masked or suppressed by the expression of another gene or more other genes. In this, more than one gene controls a specific character such as fur color, etc.
Epistasis is of different types such as dominant epistasis, recessive epistasis depending upon the effect of genes.
Here, the progenies with AABB genotype show black colored fur, the progeny with Aabb show brown colored fur, the progeny with genotype aaBB show yellow colored fur, and therefore, the progeny with genotype aabb i.e., both the recessive genes will show white colored dog fur.
Therefore, the correct option is D.

desired product.
I’m stuck on this one any advice?
The order for rDNA is to identify a target gene, select a plasmid, use a restriction enzyme, gene insertion, use ligase, introduce the recombinant DNA and detect recombinant cells. rDNA involves genetic recombination.
Recombinant DNA (rDNA) technologies are used in molecular biology laboratories to create chimeric DNA molecules containing nucleotide sequences from different species.
Recombinant DNA techniques can be used to identify and sequence genes, as well as to discover gene function.
The sequential steps of rDNA technologies are as follow:
Identify a gene of interest.Select a DNA plasmid to be used.Use restriction enzymes to cleave the plasmid DNA.Introduce the gene of interest in the plasmid.Use ligase enzymes to join both nucleotide sequences.Introduce the recombinant DNA molecule into the host cell.Detect and replicate the cells containing the desired recombinant DNA molecule.Learn more in:

what organism will you choose to modify and why did you choose it?
Answer:
Answer:Genetic modification is a technique to change the characteristics of a plant, animal or micro-organism by transferring a piece of DNA from one organism to a different organism. This is done through targeted removal of the desired genes from the DNA of one organism and adding them to the other organism.Crop plants, farm animals, and soil bacteria are some of the more prominent examples of organisms that have been subject to genetic engineering.

In agranulocytes, what happens to the cytoplasm as the cell ages?
Answer:
As the cell ages the volume of cytoplasm increases, enzymes that synthesize DNA move from the nucleus to the cytoplasm, and there is a gradual build up of lipofuscin. While it is unclear how this directly affects the cell, it is known that once the DNA migrates from the nucleus it is unable to synthesizes enzymes.

Pollen makes it easier to get seeds out of fruit so that they can grow.

Pollen is what makes fruit taste good, so animals will eat it and spread seeds.
What is it????
Answer:
I think its D.
Explanation:
Pollination allows plants to improve genetic diversity within their species and, in some cases, plants will cross-pollinate with other flower varieties. This creates a heartier, more genetically diverse plant population and sometimes drives a mutation that results in a new species or hybrid.

If a mutation occurs such that splicing does not remove one of the introns in a gene, what effect will this have on the protein encoded by that gene
Translation will continue, but it is likely that a nonfunctional or aberrant protein will be made as a result of this effect.
Mutation is described as the alteration in the genetic sequence caused by varying effects. Diseases and exposure to dangerous materials or elements (like x-rays) can cause mutation.
However, when alteration in a genetic sequence is effected such that the splicing that occurs prior to mRNA translation, does not remove a segment of a DNA or RNA molecule (which does not code for protein), and this will disrupt the gene sequence. Although, translation will continue, but the protein synthesised will be a nonfunctional or abnormal one.
