The answer is x-linked recessive. It is apparent that the color blindness affects the males hence it's caused by a sex-linked recessive gene. Males have XY homologous chromosomes. The X sister chromosome has more genes than the Y sister chromosome, hence most males are hemizygous for sex linked genes. This means that even recessive genes on the X chromosome are likely to be expressed in males.
Answer: B
Explanation:
Ammonia is so toxic that it can be transported and excreted only in large volumes of very dilute solution. As a result most terrestrial animals simply don't have access to sufficient water to routine excrete ammonia.
The main advantage of urea is its very low toxicity. Animals can transport urea in the circulatory system and store it safely in high concentrations. Also much less water is loss when a given quantity of nitrogen is excreted in a concentrated solution of urea than would be in a dilute solution of ammonia.
Answer:
Some practices from the recommended list of physical/cultural control that you could do year-round to help control pests are as follow:
1. We can use those plant species that are more competitive. These plant species include release of chemical toxins that suppress other plants and insects.
2. Use of large Hight quality seeds.
3. By using narrow spacing in row and increasing seeding rate.
4. By using shallow seeding technique which allow desired plant species to grow and develop faster above the surface of soil.
5. By ensuring that our plant species is perfectly placed in that growing environment which is optimized with every specs.
6. By rotating the crops
7. By rotating plant species with different growing cycles and seasonal cycles.
8. By rotating herbicides with alternative modes of action to delay the herbicide resistance development.
Answer:
1. Cell
2. cell theory
3. Organismal theory
4. resolving power
Explanation:
The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).
2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.
It states:
1. Living organisms are made up of cells.
2. Cells are the basic unit of life.
3. Cells are formed from pre-existing cells.
4. Energy flows inside the cell.
5. DNA is passed on from cell to cell.
6. All cells have the same basic chemical composition.
3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.
4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
Answer:
The correct sequence of muscle contraction from first to last is given below
Explanation:
step 1 myosin head interacts with actin
step 2 ATP binds to myosin head
step 3 ATP is converted to ADP and Pi
step 4 ADP and pi are released from myosin
step 5 Myosin head pivots in the power stroke
step 6 Myosin head is cocked back.
