Show how artificial selection could be used to develop a new breed of wheat with higher fiber content
Answers
Answer:
get wheat that has the desired content (in this case high fiber content)
breed them
amongst the offsprings/ wheat produced, select the ones with highest fiber content
breed them
repeat this process for many generations
Explanation:
Artificial selection is a process of selective breeding where humans choose certain traits to breed for in plants or animals.
What would happen in case of wheat?In the case of wheat, we could use artificial selection to develop a new breed of wheat with higher fiber content by selecting individual plants with the desired traits and breeding them together over several generations.
Below are the steps:
Identify wheat plants with higher fiber content: The first step would be to identify individual wheat plants that have naturally higher fiber content. This could be done by analyzing the fiber content of different varieties of wheat and selecting those with the highest fiber content.
Crossbreed the selected plants: Once we have identified wheat plants with high fiber content, we can crossbreed them to create a new hybrid variety. This involves taking the pollen from one plant and fertilizing the flowers of another plant with it. The resulting seeds will have a mix of genetic traits from both parent plants.
Select the desired traits in the hybrid plants: After the hybrid plants have grown, we would need to evaluate them for their fiber content. We would select the plants with the highest fiber content and use them as parents for the next generation of plants.
Repeat this process for several generations: The process of selective breeding would be repeated over several generations, with each generation being evaluated for fiber content and only the plants with the highest fiber content being used for breeding. This would increase the likelihood of producing a new wheat variety with consistently high fiber content.
Test and refine the new wheat variety: Once a new wheat variety with higher fiber content has been produced, it would need to be tested for its nutritional value, taste, and other characteristics. If the new variety meets the desired criteria, it could be released for commercial production.
In summary, artificial selection can be used to develop a new breed of wheat with higher fiber content by selectively breeding individual plants with high fiber content and repeating the process over several generations until a new variety with consistently high fiber content is produced.

Answers
In the epiphyseal plate, the microscopic zone in which chondrocytes undergo rapid cell division and become aligned into longitudinal columns of flattened lacunae is called the: zone of proliferating cartilage.
Longitudinal growth of long bones is carried out by the endochondral ossification process.
This process consists of the proliferation, hypertrophy and apoptosis of chondrocytes with vascular invasion and mineralization of the cartilaginous matrix.
In the epiphyseal plate, the proliferation cartilage zone is contiguous with the reserve cartilage zone in the direction of the diaphysis.
In this area the chondrocytes undergo mitosis, forming axial isogenic groups and organizing themselves in well-defined longitudinal columns.
As a consequence of this active mitosis, the layer thickens and the entire plaque grows longitudinally.
In this microscopic zone, cells are larger than the reserve zone and actively synthesize collagen (type II and XI) and other cartilaginous matrix proteins.
Therefore, we can conclude that the zone of proliferating cartilage is where chondrocytes undergo rapid cell division and become aligned into longitudinal columns of flattened lacunae.

First step Last step Answer Bank Glucose + ATP — glucose 6-phosphate + ADP Glucose 6-phosphate fructose 6-phosphate Fructose 6-phosphate + ATP → fructose 1,6-bisphosphate + ADP Fructose 1,6-bisphosphate — dihydroxyacetone phosphate + glyceraldehyde 3-phosphate Dihydroxyacetone phosphate — glyceraldehyde 3-phosphate
Answers
Balanced biochemical equations for the reactions in the catabolism of glucose to two molecules of glyceraldehyde 3-phosphate (preparatory phase of glycolysis):
1. Glucose + ATP → Glucose 6-phosphate + ADP
2. Glucose 6-phosphate → Fructose 6-phosphate
3. Fructose 6-phosphate + ATP → Fructose 1,6-bisphosphate + ADP
4. Fructose 1,6-bisphosphate → Dihydroxyacetone phosphate + Glyceraldehyde 3-phosphate
5. Dihydroxyacetone phosphate → Glyceraldehyde 3-phosphate
In the first step, glucose combines with ATP (adenosine triphosphate) to form glucose 6-phosphate and ADP (adenosine diphosphate). In the second step, glucose 6-phosphate is converted into fructose 6-phosphate. The third step involves the conversion of fructose 6-phosphate into fructose 1,6-bisphosphate by utilizing ATP and producing ADP.
The fourth step breaks down fructose 1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. Finally, dihydroxyacetone phosphate is isomerized to glyceraldehyde 3-phosphate in the last step.

You have learned that each one of your cells contains one copy of your unique genome. Given the fact that all the cells in one human contain the same DNA, how is it possible that our cell types are so different, resulting in four different tissue types?
Answers
Answer:
See the answer below
Explanation:
Yes, the cells in one human contain the same DNA. However, during gene expression, not all the genes are expressed for every cell. Only a specific region of the DNA is expressed in cells and the cells in which the same DNA region is expressed end up performing similar roles in the body of organisms. The portion of the DNA that is expressed dictates the function which these cells will serve. This is called the differentiation of cells.
Cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.
The human body contains approximately 200 cell types, which can be classified into four types of tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
All these tissues and cell types are derived from three embryo layers, i.e., ectoderm, mesoderm, and endoderm.
The process of differential gene expression from these three embryo layers leads to the development of different types of cells/tissues in different regions of the developing embryo.
For example, the expression of the connective tissue growth factor (CTGF) gene has been associated with the generation of connective tissue during embryo development.
In conclusion, cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.

The broad portion of the leaf that carries out photosynthesis is called the blade. The blade is the flattened portion of the leaf that is responsible for carrying out photosynthesis, which is the process of converting light energy into chemical energy that the plant uses to fuel its growth and metabolism.
A blade is a thin, flattened section of a plant's leaf that is primarily responsible for photosynthesis. It is the large, flat, expanded part of a leaf that is located above the stem. The blade is made up of cells that contain chlorophyll, which is a green pigment that absorbs light energy from the sun and converts it into chemical energy.
The blade's surface is usually smooth and is covered with a waxy coating called the cuticle, which helps to prevent water loss and protect the plant from environmental damage.

What change would increase the rate of oxygen diffusing from lung alveoli into the blood?
Answers
An increase in the hemoglobin concentration of the red blood cells would increase the rate of oxygen diffusing from lung alveoli into the blood.
The capillaries (small blood vessels) lining the alveolar walls allow oxygen to diffuse from the alveoli to the blood throughout this process.
Hemoglobin in red blood cells absorbs oxygen as it enters the bloodstream.
Then, as the blood returns to the heart, the heart sends the oxygen-rich blood through the arteries to the body's tissues.
The alveoli are where blood is infused with oxygen (air sacs).
Small blood arteries called capillaries are located quite close to the alveoli.
Oxygen and carbon dioxide travel along the concentration gradient due to the alveolar and capillary walls' extreme thinness.
This motion is referred to as diffusion and an increase in the hemoglobin concentration of the red blood cells would increase the rate of oxygen diffusing from lung alveoli into the blood.
