Answer:

1.3 million Earths

Explanation:

Solitary bees live and nurture their young on their own. Without the assistance of another bee, each female bee constructs and protects her own nest, lays her own eggs, and harvests nectar and pollen for her brood.

1) This circumstance indicates that the colony lacks a queen and has laying workers. If the colony is left without a queen for an extended length of time, it may develop laying workers since worker bees are females with ovaries and the ability to lay eggs. They will, however, be able to lay only infertilized eggs.

2) This state of bees in honey bees indicates that the queen is generating inbred progeny for a variety of causes. Perhaps the queen is a weak queen, meaning she did not mate properly or was unable to produce a large number of eggs, or she was forced to mate with their brothers due to low bee density. Worjer bees detect inbred eggs and expel them from the hive after the queens oviposit them, resulting in a splotchy brood pattern.

3) This scenario occurs when the colony is a fresh swarm that is rapidly growing. The existence of adult workers and a large number of capped brood suggests that the queen was present at some stage.

4) There are many adult workers present in a bee colony, as well as many capped broods and queen cells at various developmental stages, indicating that the colony has swarmed to a new home, with the old queen abandoning the previous hive as the new queen will soon emerge from the queen cells.

5) This signifies that the colony has swarmed and may swarm again once the new queen develops. Moderate mature workers and capped brood with numerous queen cells indicate that one group of bees swarmed to create a new hive with its old queen and that the next group will swarm soon after the new queen is hatched.

6) This signifies that the colony will swarm again soon and is prepared to swarm once the queen is fully matured for mating and egg laying after mating.

7) This circumstance indicates that the bee colony has surpassed its queen. When the present queen is not doing well in the hive, the female worker bees develop a new queen to supersede or take the old queen's position. As a result, bees create more than one cell in a hive to assure the birth of a healthy queen.

8) This state in a hive indicates that the colony has swarmed and will not swarm again. A hive with a lot of eggs indicates that the colony is swarming and will continue to swarm if there are too many queen cells. As a result of the swarming of colonies, there are no capped broods.

An intermediate community emerges in sand dunes as the sand gradually becomes stabilized, allowing certain types of plants to grow and establish themselves. These plants are typically able to survive in harsh and dry conditions, and they can trap and hold sand with their roots and stems, leading to further stabilization of the dune. As the dune becomes more stable, larger plants and trees can begin to grow, and the community becomes more complex and diverse.

In the early stages of dune formation, only a few species of plants are able to survive in the harsh, sandy environment. These are typically pioneering species, such as marram grass and sea rocket, which have adaptations that allow them to survive in the harsh conditions. As these plants grow and spread, they trap sand with their roots and stems, leading to the formation of small mounds or hummocks. Over time, other plant species, such as beach heather and sand sedge, may begin to grow on these mounds, forming an intermediate community. As the dune continues to stabilize, larger plants and trees, such as pine and oak, may begin to grow, leading to the development of a more complex and diverse ecosystem.

Gravity is the natural downward force, proportional to mass. Gravity is strongest at Earth's surface.

Explanation:

Lymph moves through the body via the contraction of muscles surrounding the lymphatic vessels. The movement of the skeletal muscles during physical activity helps to squeeze the lymphatic vessels, propelling the lymph forward. Additionally, the valves within the lymphatic vessels prevent backflow and assist with the movement of lymph towards the heart. The spleen, heart, and lungs do not play a significant role in moving lymph through the body.

Proteins obtained from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where they are eventually transported to lysosomes, the plasma membrane, or secretion. As was already mentioned, the Golgi apparatus also produces sphingomyelin and glycolipids. The complex polysaccharides that make up the cell wall are also created in plant cells at the Golgi apparatus. The extensive range of cellular components that go down the secretory pathway are thus processed by the Golgi apparatus.

The invention of microscopes made it possible to learn more about single-celled organisms, which led to the need for additional kingdoms beyond the traditional plant and animal kingdoms. As microscopes improved, scientists were able to see the complexity and diversity of single-celled organisms, which they realized could not be adequately classified as either plants or animals. This led to the creation of the kingdom Protista, which includes a wide range of unicellular eukaryotic organisms such as algae, protozoa, and slime molds. The development of other kingdoms, such as Fungi and Monera, followed as scientists continued to study and learn about different types of organisms. Therefore, the invention of microscopes was most responsible for creating the need for the additional three kingdoms.

The term for a close association between organisms of two or more species is Symbiosis. Option A. is correct.

Symbiosis is a biological relationship that benefits two different species that are in direct contact. In general, there are three main types of symbiotic relationships, each distinguished by the nature of the benefits that are provided to each species that participates. They are mutualism, commensalism, and parasitism.

Mutualism describes the close association of two or more species in which both benefit. Commensalism describes the close association of two or more species in which one species benefits and the other is neither harmed nor helped. Parasitism describes the close association of two or more species in which one species benefits while the other is harmed.

Therefore, Option A. symbiosis is correct.

The usual results of MCV and RDW in alpha thalassemia can be low MCV and high RDW.

Explanation:-

In alpha thalassemia, the usual results of the mean corpuscular volume (MCV) and the red cell distribution width (RDW) can vary depending on the severity of the disease.

The mean corpuscular volume (MCV) is a measure of the average size of a red blood cell. It is usually reduced in alpha thalassemia, particularly in more severe forms. A low MCV is an indication of microcytic anemia. This is due to a deficiency of alpha globin chains.

Red cell distribution width (RDW) measures the variation in size of red blood cells. In alpha thalassemia, the red blood cells are often of different sizes, which leads to a higher RDW. An elevated RDW indicates anisocytosis, which is a term used to describe red blood cells of different sizes.Therefore, the usual results of MCV and RDW in alpha thalassemia can be low MCV and high RDW.

Answer:

All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night.

In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die. The death of autotrophs would lead to a chain reaction of the death of all higher order organisms. Mankind could survive on food stuffs on hand, but only for a very short time. It has been said that any western society, its members are just 3 meals away from revolution.

Social order would be completely lost during the initial food riots. Once the processed and packaged food supply is exhausted, it would be the law of the dying jungle. The strong and well armed would take from the weak and ill prepared. Livestock and game would be slaughtered as the next to the last food source disappeared. The shear volume of death would foul the water spreading pestilence and disease. In one or two years bands of humans would prey on other humans as they degenerate into cannibalism. There could be a few humans in protected bunkers and hideaways, but they too would eventually succumb to starvation or despair as the world died.

The fact that plants stopped converting CO2 into O2 would be of little consequence. Man would die of hunger 1000 years before oxygen was ever an issue.
