The correct answer is option B, that is, crossing over.
Crossing over or chromosomal crossover refers to the interchange of genetic substance between the two homologous chromosomes non-sister chromatids, which leads to the formation of recombinant chromosomes at the time of sexual reproduction.
It takes place in the pachytene stage of prophase I of meiosis at the time of a procedure known as synapsis.
B. Leukoctyes
C. Erythrocytes
D. Lymph
Our blood contains blood plasma, leukocytes, and erythrocytes but does not contain lymph. Lymph is a separate body fluid, transported by the lymphatic system.
Blood consists of several components: blood plasma, leukocytes (white blood cells), and erythrocytes (red blood cells). Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It makes up about 55% of the body's total blood volume. Leukocytes are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. Erythrocytes, or red blood cells, are cells present in blood in order to transport oxygen. On the other hand, lymph, although a body fluid, is not a part of the blood. It is mainly composed of white blood cells and is transported by the lymphatic system, separate from the circulatory system that transports blood.

The biosphere will sustain when the inflow of additional carbon atoms is low due to ecosystem services.
The ecosystem services refers to the deteritous activity done by the microbes present in the soil which convert the soil organic matter into available carbon dioxide to the environment.
Hence, the biosphere will receive the flow of carbon atoms by the activity of deteritous.

Answer:
The oxygen and carbon dioxide in the lower layers of the troposphere (that touches Earth) allow life to exist as organisms can respire and plants can photosynthesise. The atmosphere also helps to keep the Earth warm by trapping solar energy.
Explanation:
The graph that would best predicts the change in the break length of the bird population is that of the third graph.
The seed-eating birds includes the Sparrows and finches, and redpolls. Grouse has different sizes of beaks as per the body ratio. Evolution and natural selection play a crucial role in the development of the beaks. The shape of the break determines the type and shape of seed it will eat.
As per the graph given the length of beaks will increase as the number of individual birds increases. Thus the diversity of breaks depends on the diversity of the species. Hence the option C is correct.

Explanation:
The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.
The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.
These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.
The similarity in appearance between the Moon and the stone sphere is due to the spherical shape of both objects, causing a uniform and diffused reflection of light.
The similarity in appearance between the Moon and the stone sphere in the image can be attributed to the way light interacts with spherical objects. This phenomenon is primarily due to the principles of reflection and the geometry of spherical shapes.
Light Reflection: Both the Moon and the stone sphere reflect sunlight. The Moon is illuminated by the Sun's rays, and the stone sphere, although much smaller in scale, reflects ambient light or artificial light sources.
Spherical Shape: Spherical objects have a unique way of reflecting light. When light falls on a spherical surface, it is refracted, scattered, and reflected in various directions. This scattering of light creates a uniform and diffused illumination on the entire surface of the sphere, resulting in a soft and evenly distributed glow.
Absence of Sharp Edges: Spheres lack sharp edges and corners that can create shadows or abrupt changes in light intensity. This absence of shadows and the uniform distribution of light contribute to the similar appearance of the Moon and the stone sphere in terms of their illuminated surfaces.
In summary, the shared appearance can be explained by the spherical shape of both objects, which results in a gentle and uniform distribution of reflected light, creating a soft and luminous appearance in the image.
