How is editing the genetic code different from artificial selection?
Answers
Answer:
Editing genetic code is when you take something already born and editing its dna. Artificial selection is when you edit somethings dna before it's born.
Editing genetic code creates new trait in the species but artificial selection select the trait already present in the species.
What are genetic code editing and artificial selection?Humans can transform a species' members through genetic engineering and artificial selection to make them better suited to human demands. The method for transformation, however, is distinct.
Artificial selection selects for existing qualities in a species, whereas genetic engineering develops new traits. Following the cutting of the DNA, researchers employ the cell's own DNA repair mechanism to add or remove fragments of genetic information.
Artificial selection differs from natural selection in that it refers to selection used by people to generate genetic change. When artificial selection is used, the characteristics or traits are modified.
Therefore artificial selection selects species having new traits already present and genetic code editing creates new traits.

For which method of determining population size is the population not aware of the sampler’s presence?
a. mark/recapture
b. direct observation
c. sampling
d. indirect observation
Answers
Answer:
The method of determining population size is the population not aware of the sampler’s presence is indirect observation.
D
The method in which the population is not aware of the sampler's presence is indirect observation (Option d).
Indirect observation refers to the collection of information obtained by other researchers in order to record it in specific informative materials (e.g., books, review/research papers, videos, etc.).
An example of indirect observation can be the record in a book of specific animal behaviors (e.g., the presence of marks on the ground).
In conclusion, the method in which the population is not aware of the sampler's presence is indirect observation (Option d).

Exposure to the building material asbestos has been linked to certain types of cancers. Asbestos causes mutations in the p53 gene, which controls tumor suppression. Which statement best explains why people with cancer due to asbestos exposure do not pass the mutation on to their offspring?
A. The mutation occurred in gametic cells.
B.The mutation occurred in somatic cells.
C.The mutation is recessive
D.The mutation is sex-linked.
Answers
Answer:B
Explanation:
Somatic cells are skin cells so that means it can’t be passed on to their offspring
The reason why people with cancer due to asbestos exposure do not transfer the mutation unto their offspring is because: B. The mutation occurred in somatic cells.
Cancer refers to the uncontrolled division of certain somatic cells, which then invade the surrounding tissues and interfere with the normal functioning of the human body.
Over the years, the exposure and inhaling of building material asbestos into lungs has been linked to the cause of certain types of cancers such as mesothelioma.
The building material asbestos results in the mutation of the p53 gene, which is mainly responsible for controlling tumor suppression in living organisms.
However, people with cancer due to asbestos exposure do not transfer the mutation unto their offspring is because the mutation took place in somatic cells.

Which answer correctly explains why these concepts are the basis of a theory and not a hypothesis? (5 points)
Cell theory explains how cells function rather than predicting how they function.
Cell theory has been unchanged for many decades and as a result can be accepted as fact.
Cell theory is a prediction based on observation and not a fully accepted idea.

The genotype of the individuals I-1 and that of I-2 are Aa and aa, respectively. The inheritance shows autosomal dominant trait and thus the individuals which are homozygous recessive are unaffected. Thus, the correct option is C.
What is Pedigree analysis?Pedigree analysis is used to understand the inheritance of genes from the parents to offspring. Pedigree was developed as a chart which can represent a family tree along with the family members in the order starting the top with the eldest and goes down with the latest generation downwards and shows their genetic traits, respectively.
The given inheritance pattern shows an autosomal dominant trait, the shaded symbols are the affected ones and the white symbols are unaffected.
The I-1 and I-2 are shown with a shaded symbol and a white symbol, respectively.
I-1 is affected thus, it contains the dominant allele and it can be either Aa or AA.
I-2 is unaffected thus, it contains only the recessive alleles. Therefore, the genotype will be aa.
Therefore, the correct option is C.

Explain how mutations in gametes may result in phenotypic changes in offspring.
Answers
Explanation:
A mutation is a sudden change, and in this case, it's in gametes.
If the change happens because of or during meiosis, the mutation is carried and may affect phenotypic change in offspring. This is because the gametes are the buiding blocks for a human being's genetic code. If there is a change in it's genetics, there will be a change in how it looks.
The process of mutation in gametes results in phenotypic changes in offspring by the fact that the gametes are the building blocks of organisms that govern each and every essential function for the survival of living organisms.
What is Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of a living organism. An organism that undergoes an event of mutation is known as a mutant. While the agents that cause an event of mutation are known as mutagens.
When a mutation is induced in the gamete cells of living organisms, it may be directly inherited from parents to their offspring the fact that they are the building blocks and functional components of the living organisms. So, they result in alterations in the phenotypic expression of offspring.

(Polymerase synthesizes the complementary daughter strand by adding nucleotides to the DNA.)
4. Topoisomerase - 4. creates nicks ahead of the replication fork to relieve tension from unwinding
(The highly coiled DNA is relaxed by creating nick ahead of the replication fork in the phosphate backbone of DNA strands.)
5. RNA primase - 3. synthesizes RNA primer at the initiation point

Answers
Answer:
one of the nature given important part of our life is sun as it provides heat and light to each and every creature present in the earth which is used for cooking, growing,and and for getting vitamins like vitaminD .it generates the weather patterns and also stirs our atmosphere.thus it is quite important for human as well as for animals and plants to run their livelihood. The second one is plants as we know plants are one of the most precious gift of nature to all the living being it provides oxygen and is the the major source of food for both plants and animals.plants prevent us from the natural disasters like flood , landslide, earth quake and other natural disasters this is is quite important in Every living beings life.
Answer with Explanation:
Nature is very important for the survival of living things, including humans. We rely largely on it for almost everything. Two examples of these are the food and clothing that we get from nature. With the help of nutrients coming from plants, we are able to nourish our body and become healthy. Besides this, we can also derive fibers from plants that are needed for making clothes. These help us stay warm, thereby preventing us from getting sick.
Additional Information:
Apart from the above, "nature" plays a huge role in maintaining a person's peace of mind. For example, people go to the mountain to bathe in the forest and meditate. It helps calm the mind and reconnect with our environment.
