Anticlines and Synclines. :)
Explanation:
Genome editing is a group of technologies that enables scientists to edit an organism's DNA. One genetic editing technology is called CRISPR-Cas9, which was developed based on a naturally occurring genome editing system in bacteria. CRISPR-Cas9 uses a cell's own machinery to edit the genetic material; scientists can add or remove genetic sequences from an organism's genome. CRISPR-Cas9 can customize an organism's DNA by replacing an existing segment with a customized sequence of DNA. In 2018, a Chinese scientist announced that he had created the world's first genome-edited babies, twin girls born in November 2018. The scientist wanted to create children who were resistant to Human Immunodeficiency Virus (HIV). The Chinese scientist used CRISPR-Cas9 to disable a gene called CCR5, which encodes a protein that enables HIV to infect cells. This announcement caused outrage in the international scientific community. While genomic editing of bacteria and viruses is commonly used in science, genetic editing of humans remains highly controversial. Why do you think the news of this new use of CRISPR-Cas9 in humans generated so much anger in the research community and in the world at large? What are the dangers of genomic editing in humans?
Answer:
Explanation:
It generated anger because:
1) Human gene editing is highly controversial as humans are considered the "top" organisms and any tests conducted on humans whether it be clinical trials of medicine and such need to be approved and need to be ethical.
2) We are still years behind in terms of knowledge of genomic editing on animals and its side effects, and taking this in account, performing such editing with humans is obviously going to draw controversy as we do not know enough about genomic editing.
Dangers of editing in humans:
1) Although Crispr-Cas9 is highly accurate, it is still capable of making mistakes and we are still unsure about how those mistakes can affect the whole human. After all, the editing needs to be done in embryo for it to make a pronounced effect later in life on the grown human so any mistakes could ruin the new life of this human.
Gene editing is a technique that is used in research areas to modify genes of organisms for improving their function and to treat diseases.
Genome editing generated anger when used on Humans because:
Genome editing or any research based on humans as a subject is considered very controversial and have always created anger even in the case of clinical trials.Genome editing has been conducted on animals for years and the results and side effects are the reasons that the human specimens cannot be used for experimentation.Dangers of genome editing in humans:
The accuracy rate of gene editing is still not 100% and they are chances that unintended changes can occur during editing.These mistakes and errors can affect the human as a whole and will ruin its whole life.The possibility of getting cancers and getting vulnerable to biological attacks makes gene editing in humans a disadvantage.Thus, human gene editing is a controversial issue.

Gymnosperm
C. Non vascular, Vascular
seedless, Gymnosperm,
Angiosperm
D. Angiosperm, Gymnosperm,
Vascular seedless, Non vascular
Answer:
The correct order of evolution is C- Non Vascular, Vascular seedless, Gymnosperms, Angiosperms.
Explanation:
The first plants to evolve were the non-vascular bryophytes like fungi and algae.
The next to evolve were vascular plants that supported a vascular tissue system but lacked seeds.
Gymnosperms are vascular plants that have seeds.
The seeds produced in the gymnosperms could undergo fertilization easily as the wind acted as pollen carrier.
The next to evolve were angiosperms or flowering plants.
Flowering plants have highly modified shoots that carry male as well as female gametes.

Explanation:
The apple, celery, and potato all contain the majority of the carbohydrates, the steak, egg, contain the majority of the protein; and the olive oil and the avocado both contain the fat.
What is the significance of carbohydrates and fats in the human body?These are the macromolecules, such as carbohydrates, which are the main part of the diet that is easily broken down to give rise to energy, and there are other sources of proteins and fats that perform the same functions. These foods are found in vegetables, fruits, nuts, and other foods and provide nourishment to the human body.
Hence, the apple, celery, and potato all contain the majority of the carbohydrates, the steak, egg, contain the majority of the protein; and the olive oil and the avocado both contain the fat.

Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusion across a membrane
Answer:
D diffusion across a membrane
Explanation:
Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.
An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.
Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

A. Cell theory
B. DNA and molecular evidence
C. Process of photosynthesis
D. Method of protein synthesis
Answer: The answer is A cell theory.
Explanation: For our cells to be as developed and complex as they are today a huge evolutional process was necessary. This process is explained in the cell theory
DNA and molecular evidences are the additional evidences to support Darwin's theory. The correct option is B.
What is Darwin's theory?According to Darwin's theory, all species of organisms emerge and develop through natural selection of slight, inherited variations that significantly raise the individual's capacity to compete, stay alive, and reproduce.
It is backed up by research from a wide range of scientific disciplines, as well as genetics, which shows that DNA from different species is similar.
Fossils, embryological studies, anatomical and morphological characteristics, and molecular biology are examples of evidence that support the theory of evolution by comparing DNA sequences.
Thus, the correct option is B.

What is the benefit of using a shortcut in a reaction between two chemicals? A shortcut would ensure a safer reaction. A shortcut may provide a faster reaction. A reaction with a shortcut would yield more chemical output. A reaction with a shortcut would require less chemical input.
Answer:
A shortcut may provide a faster reaction
Explanation:
Chemical reactions occur in a particular manner and speed if allowed to occur normally. However, shortcuts can be used for the essence of making the reaction proceed much faster than it naturally would. Catalysts are the substances used to provide these shortcuts.
A catalyst is a substance that increases the rate at which a chemical reaction occurs without being chemically used up in the reaction. A catalyst speedens up the chemical reaction by decreasing the activation energy. The activation energy is that energy needed for a chemical reaction to kick start. The higher the activation energy, the slower the reaction proceeds.
A catalyst, thus, creates a shortcut by lowering the activation energy of the chemical reaction, allowing it to proceed faster than when a catalyst is not used.

What does Saccharomyces cerevisiae (Baker’s yeast) need to survive?
Answer:
Food (Sugars)
Explanation:
S. cerevisiae feeds on sugars for energy, in the process producing carbon dioxide and alcohol (this is fermentation in a nutshell). The carbon dioxide bubbles get trapped in the dough, creating the lift that makes the dough rise. The alcohol, meanwhile, evaporates when baking, transforming into gas that also contributes to the rise of the bread. The alcohol, along with acids produced during the fermentation process, impart that wonderful flavor and aroma associated with yeast-leavened breads.

Answer:
I think it's that they have two alleles for the gene
The statement that Mendel’s pea plants had either purple or white flowers means that the plants have two alleles for the gene.
MENDEL'S LAW:Gregor Mendel is regarded as the Father of genetics due to his immense contribution to knowledge of genetic inheritance.
According to Gregor Mendel, a gene consists of two alleles, which individually encode different phenotypes of a particular trait.
