Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide exchange in the DNA. When they compared gene sequences, they saw same number of nucleotide bases. Which type of mutation had most likely occurred? deletion insertion inversion substitution
Answer:
substitution
Explanation:
A substitution is a point mutation where a nucleotide base (either adenine, guanine, thymine or cytosine) is replaced by a different base pair. In contrast to insertions or deletions, substitutions don't change the number of bases in the DNA sequence. Moreover, inversions are large genetic rearrangements where the genetic sequence is reversed. A substitution may have different effects: change a codon to another (changing the protein sequence when codons are translated into amino acids), produce a stop codon, cause synonymous mutations (i.e., neutral mutations that don't alter the amino acid sequence due to the degeneracy of the genetic code), etc.

How are meiosis and mitosis different?
Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Answer:
Mitosis produces two diploma somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid gametes that are genetically unique from each other and the original parent cell.
Emily’s friend Mark recently learned that he was adopted; although his parents tried to keep it a secret for as long as possible, he realized that he could not be their biological son because he has brown eyes, a dominant trait, while they both have blue eyes, a recessive trait.
Is Mark correct in assuming he must be adopted because of his difference in eye colour?
Answer:
Explanation:
Two blue eyed parents have a brown eyed baby Although it is uncommon, parents with blue eyes can have children with brown eyes. The inheritance of eye color is more complex than originally suspected because multiple genes are involved.

the human heart starts beating around_____days of embryonic development(. )
a) 22
b) 21
c) 23
d) 24
Answer:
a) 22
Explanation:
Cardiogenesis which is the formation of the heart begins by day 21. The heart begins to form as paired tubes. By days 22 - 23 of embryonic development, the heart begins to beat. This represents the formation of the first vital organ of the body and it also causes the formation of left-right asymmetry of the body.
The days are counted from the day of the last menstrual period.

The pigment plants have that they use for photosynthesis is called _________.
Answer:
chlorophyll
Explanation:
The mechanism by which light energy can be transformed into chemical energy by synthesis of organic compounds is chlorophyll, a member of the most significant pigment class involved in photosynthesis. In nearly all photosynthetic species, e.g. green plants, cyanobacteria and algae, the use of chlorophyll is identified. It consumes light energy and is then used for the conversion to carbohydrates of carbon dioxide.

If capital D = the allele for dimples, and lowercase d = the allele for NO dimples, what percentage of the offspring will show having dimples, with parents having genotype Dd (capital D and lowercase d) and genotype dd (two lowercase ds)?
If D is the allele for dimples and d is the allele for no dimples, a percentage of offspring with genotypes Dd is 50% and 50% dd will be produced with no dimples.
How will the allele for dimple express?The dimple appears when the D is present, which occurs in both the purebred dominant case (DD) and the heterozygous case (Dd), so when the dd is present, no dimple is seen. The dimple is dominant over the no dimple, so when the heterozygote Dd crosses with the purebred dd then 50% will have dimples and the other 50% won't, as the heterozygotes will produce both D and d types of alleles that will combine with d to make two types of offspring.
Hence, if D is the allele for dimples and d is the allele for no dimples, a 50% percentage of offspring with genotypes Dd and 50% of offsprings with genotype dd will have no dimples.

What are the challenges of traveling to and living on Mars?
Answer:
Here I hope this can help you with your question! :)
Explanation:
You might be travelling with other astronauts in a journey that will take between seven and 12 months, packed in a tight space. So you’ll need to stretch and probably find a way to have part of the spacecraft spinning to create artificial gravity. Having no gravity for a long time can cause a lot of painful health problems for astronauts. Then there’s the powerful cosmic radiation that comes mostly from our Sun. It can damage electronic equipment on board and create health problems for the crew. You and the crew will have to solve these problems on your own. The atmosphere is not breathable: it is only 1% the thickness of our atmosphere, mostly made of carbon dioxide, argon, and nitrogen with only a small amount of oxygen. Growing plants on Mars is not going to be easy. The soil is really salty and acidic. It is still unclear if we should bring bacteria to Mars to help plants grow (as they do on Earth). Finally, I would say any mistake in flight or during the exploration can hurt or kill you. The room for error is really narrow. Why on Earth would you engage in such a dangerous, life-threatening endeavour? I guess the answer lies in what has made humans explore throughout the centuries. We are always looking for the next frontier.
Answer:
- Travelling from Earth to mass requires a greater magnitude of escape velocity in order to overcome the Earth's gravitational attraction.
- Travelling to Mars is a great distance which is approximately the twice of Earth's distance from the sun (approximately 3.0×10^11 m), hence the Traveller has a possibility of not reaching the destination.
- Travelling to Mars requires a skilled Traveller and experienced, yet those travellers are scarce allover the World.
- It is also very expensive.
- Mars has a different and a greater gravitational attraction than that of the earth, hence a person of earth may not cope with it.
-Mars is very hot than Earth, hence the living on it is affected by the climatic diversion

Answer:
The answer is "running water or glaciers".
Explanation:
The material is placed if erosion agents can longer carry sand. For instance, if another fluvial water slows at the river mouth, soils become rivers. The four key reasons for accumulation was its movement of reinforced the fact material surface, air, ice, liquid, and inertia, accumulated at the loss with enough kinetic energy throughout the fluid to create substrate layers. Accumulation can also apply to natural head moves or processes create of soil.

What type of energy is made during respiration
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Answer:
The source of the energy required to regenerate ATP is the chemical energy stored in food (glucose) The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. So I believe it would be chemical energy

All of the following are reasons for regulation of gene expression EXCEPT -
Answer:
There are three broad levels of regulating gene expression:
transcriptional control (whether and how much a gene is transcribed into mRNA)
translational control (whether and how much an mRNA is translated into protein)
Explanation:
The first method of controlling transcription is by regulating the quantity of mRNA that can be generated from a given gene, hence option C is correct.
What is gene expression?The level of regulation involves post-transcriptional processes that manage how mRNA is translated into proteins, repair of damaged cells are not controlled by gene expression.
The expression of an animal's genes ultimately determines its phenotype, which is influenced by environmental variables like as nutrition, temperature, oxygen levels, light cycles, and the presence of mutagens.
Therefore, despite the fact that every cell type in your body has the exact same DNA, gene regulation allows for each cell type to have a unique collection of activated genes, hence option C is correct.
