The most common protein produced by transgenic organisms is
Answer:
Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Most transgenic organisms are generated in the laboratory for research purposes. For example, "knock-out" mice are transgenic mice that have a particular gene of interest disabled.
The most common proteins produced by transgenic organisms are albumin, fibrinogen, and human antithrombin.
What do you mean by Transgenic organisms?Transgenic organisms may be defined as those organisms in which foreign DNA has been introduced by recombinant-DNA technology with the help of plasmid vectors.
After inserting the foreign DNA, the host organisms produces several proteins which do not belong to their point of origin. Due to the expression of these proteins, recombinant-DNA technology has been used.
Therefore, the most common proteins produced by transgenic organisms are albumin, fibrinogen, and human antithrombin.

Is it possible to have a knockout mutant plant that shows no visible phenotype that is different from the wild-type plant?
Answer:
Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).

The diagram below shows a normal fault.
In this image, a section of rock is divided by a fault plane running from top-left to bottom-right. The section of rock to the left of the fault plane is pushed above the section of rock to the right of the fault plane.
Public Domain
Which answer choice correctly explains why this diagram shows a normal fault?
The fault plane divides two otherwise identical sections of rock.
The fault plane runs from the top of the rock to the bottom of the rock at an angle greater than 45 degrees.
The block of rock above the angle of the fault plane is raised above the block of rock below the angle of the fault plane.
The block of rock above the angle of the fault plane has fallen beneath the block of rock below the angle of the fault plane.
The block of rock above the angle of the fault plane is raised above the block of rock below the angle of the fault plane diagram below shows a normal fault. Thus, the correct option is C.
What are reverse faults?Reverse faults are those in which the higher block, known as the Hanging wall, rises over the lower block, known as the Footwall. The compressive stress exerted on the soil from both sides causes this type of fault to form.
During an earthquake, the fault plane is a planar surface along which the blocks slip. These are the tectonically active parts of the world. An earthquake causes a great deal of damage to both property and people's lives.

How many chromosomes are in the gametes of an organism that has 88 chromosomes in its diploid cells?
Answer:
It is a worldwide universal truth that all living organisms produce gametes which comprised of a quasi or half number of Chromosomes in contrast to their inventive number of chromosome. Generally, in simple words, the gametes ploidy will be going halves on than the ploidy of the organism.
Ovum is the ‘female’ gamete which is truly the new-fangled individual of the species. It is basically, the solo cell in which disunion progression take place and baby will make. The ovum being single cell comprised of, ample chromosomes set. In humans Ovum chromosomes is 22 and one more X chromosome overall, making it 23 chromosomes. �The ovum required chromosomal set to become doubled and to the concert itself in the baby by development and cell division. This can be done once after when comprehensive and identical chromosomes of sperm combined with ovum after mating. Therefore, humans body cells comprised of 46 chromosomes.

Describe the scientific explanations of the origin of life of Earth.
The scientific experiment on the origin of life on earth is according to the RNA world hypothesis, which is supported by many scientists, RNA rather than DNA was the earliest genetic molecule of life on Earth.
What is the origin of life on earth?The natural process through which life emerges from non-living materials, such as simple organic compounds, is known as abiogenesis or biopoiesis. Abiogenesis theories can be broken down into three basic stages: geophysical, chemical, and biological. Therefore, biogenesis, protobiogenesis, and biopoiesis are other terms for the origin of life.
Although the signature traits of living systems are explained by the creation of a self-replicating catalytic enzyme, the origin of the photobiological molecule itself is not explained.
Therefore, according to a scientific experiment on the genesis of life on Earth, RNA rather than DNA was the first genetic molecule of life on Earth.

Answer/Explanation:
Using body systems respiratory, circulatory, and muscle.
The respiratory, circulatory, and muscle work together because the circulatory carries blood to the muscles and respiratory systems. The respiratory systems gives breathe and makes it able to live so the other two can function. The muscle systems helps move using the breath of life and the blood from the circulatory.

Name a part of the hydrosphere that is far away from you. Then, explain how water in that part of the hydrosphere could travel through the water cycle and end up as a puddle of rainwater where you live. Include an explanation of any changes in the state of water (solid, liquid, gas).
Answer: Hi
Explanation: I need answers too
An example of a part of the hydrosphere that is far away from me is the Arctic Ocean. The Arctic Ocean is located in the polar region and is covered by a layer of ice for most of the year.
What is hydrosphere?Water in the Arctic Ocean can travel through the water cycle by a process called evaporation. As the sun shines on the Arctic Ocean, it can cause some of the water on the surface to evaporate, turning it into water vapor. This water vapor can then travel through the atmosphere and condense into clouds as it cools down. As the clouds move over different regions, they can release precipitation, which can fall as rain or snow depending on the temperature.
If the water that originated from the Arctic Ocean falls as snow, it could accumulate and eventually form glaciers or ice caps in higher elevations. As the temperature warms, the snow and ice can melt, turning into liquid water. This water can then flow downhill and eventually reach rivers, lakes, and oceans, where it can evaporate again and continue the water cycle.
If the water that originated from the Arctic Ocean falls as rain, it could end up in a puddle where I live if it lands on the ground and doesn't flow into a body of water. As the temperature warms, the puddle can evaporate and turn into water vapor, which can then become part of the atmosphere and continue the water cycle.
Overall, water in the hydrosphere can travel through different states (solid, liquid, gas) as it moves through the water cycle and can end up in different regions, including where I live, through precipitation and other natural processes.
