The ecological factors influence in pond ecosystem by providing the basic structure and materials that the ecosystem needed.
Oxygen, carbon dioxide, water, light and nutrients are the abiotic factors whereas the biotic components are algae, bacteria, protozoa and other organisms are the ecological factors that greatly influence the pond ecosystem. If one of the factor is missing or eliminated from the pond ecosystem the whole ecosystem will disturb and can't work properly. For example, if light is eliminated from the ecosystem, no producers can grow and ultimately death and destruction of the whole ecosystem occurs.

Ecological factors, such as temperature or trophic relationships between organisms, influences the characteristics of a population in a certain habitat because they make it possible for organisms to have everything they need in the environment to feed, reproduce and survive.
An ecosystem is a system that groups together different populations of animal and plant species which share all the resources available in the same environment. Interactions develop between the elements of an ecosystem, such as energy exchange, food or trophic relationships and all this makes it possible to maintain life in the ecosystem. There are many natural habitats where an ecosystem develops, such as rivers, forests, swamps, deserts, among others. However, there are also artificial habitats created by humans, such as ponds. Ponds have fresh water like lakes, but are smaller (although it is important to consider that ponds can also be formed naturally by water retained or stagnant in a depression in the ground that is usually formed by rain water). Some of the organisms in this ecosystem live in ponds all their lives, while others are transient and visit them only to reproduce and/or feed. Ponds, being habitats where animal and plant species coexist, are susceptible to the influence of environmental factors.
Ecological factors influence the life of any living organism. They can be:
Abiotic: non-living elementsSunlightTemperatureWindHumidityAtmospheric pressurePresence of metals in the soilThe pH of the water2. Biotic: living organisms
Presence of other species that can be preys, competitors, predators or parasites.We have to consider that in a pond we can find microscopic algae that use sunlight and mineral substances in the water, perform photosynthesis and then are eaten by herbivorous animals such as fish, frogs and toads (which can also eat insects as do shrews). These, in turn, are eaten by carnivorous animals, such as herons.
It must be taken into account that for life to take place in a correct and natural way, it is necessary that all the ecological factors are correct. So, the presence and quantity of ecological factors influences how the habitat develops since, for example, with the necessary and sufficient amount of sunlight, plants survive by photosynthesizing and these plants are food for herbivorous animals that in turn will be food for other carnivorous animals. This would then alter the food chain, as the population of the different species would start to decrease because it represents a series of organisms that eat each other in such a way that energy and nutrients flow from one to another.
In addition, the temperature must be adequate for vegetation to grow and for animals to survive. Therefore, it is important that the environmental factors present in the habitat are the right ones and in the right quantity, otherwise the balance of the ecosystem can be lost and thus seriously threaten the survival of the species. In this way, any factor that is altered will affect the ecosystem of the pond.

The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
Answer:
Last choice: ribose; deoxyribose
Explanation:
Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.
Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base: adenine, thymine, cytosine, guanine, and deoxyribose.
Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.

Modern plant-breeding techniques (artificial selection in action) have reduced genetic variability in many of our most commercially valuable plants. To most people, that would generate a shrug. However, a biology student that has studied evolution understands the problem with this. Briefly explain why there is an issue with this.
Answer:
There is an issue with the artificial selection.
Explanation:
There is an issue with this artificial selection because the genetic variability is reduced when we do again and again the artificial selection. In the artificial selection, the selected genes are combined with the one another and does not allow natural fusion or combination of genes that is responsible for the genetic variability in the organisms so that's why we can say that this artificial selection is an issue that reduce genetic variability.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community
Answer:
The elephants are the keystone species in this ecosystem.
Explanation:
The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.
This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.

The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.
The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.
Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, employees are exposed to them and are vulnerable to harm from these chemicals.
There are many types of hazardous chemicals to be wary of, such as:
Carcinogens NeurotoxinsAcids Systemic toxins Asmogens Silica dust LeadIn the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.
The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

In meiosis, sister kinetochores are attached to the same pole of the cell during meiosis I, and sister chromatid cohesion is released during anaphase II. What would be the likely result if sister kinetochores were attached to different poles of the cell during meiosis I and sister chromatid cohesion was released during anaphase I
Answer:
sister chromatids would migrate to opposite poles in anaphase I
Explanation:
Kinetochores are multiprotein structures that establish the attachment of spindle microtubules to the chromatids during cell division (either mitosis or meiosis). Sister chromatid cohesion at the centromeres refers to the mechanism by which sister chromatids are paired and held together during meiosis I. This process (sister chromatid cohesion) is fundamental to ensure the correct orientation of chromatids on the spindle microtubules and their subsequent segregation in meiosis II. The fusion of sister kinetochores in meiosis I underlies sister chromatid cohesion during this stage of the cell division, thereby their disruption or destruction of sister chromatid cohesion would lead to separation and segregation of sister chromatids to opposite poles of the cell in anaphase I.

What are australopiths, how many groups are there, and what do they date to? Which one is derived and therefore not part of our direct evolutionary line?
Answer and Explanation:
Australopithecines were a group of ancestral animals that were very similar to chimpanzees, but had common characteristics with humans, which is something normal, when we think that these animals are one of the ancestors of human beings. These animals walked on two legs, like humans, but they had very small brains and teeth that were bigger and heavier than those of humans. There were eight groups of australopithecines and they date from 8 million to 1.5 million years ago.
Among these groups, it is believed that Australopithecus afarensis is a group that has no direct ancestry with humans, being a group that did not thrive during the evolutionary process.

Answer:
TFH cells in the germinal center
Explanation:
The Tfh cells, present in the germinal center, are responsible for maturing and stimulating the class change of immunoglobulins (such as the change from IgM to IgE). This change could stimulate the new classes of immunoglobulins to act with stimulating antibodies to produce an immune response.
It is important to point out that the germinal center is the activated point of a lymphoid follicle that contains B and T lymphocytes, which act in the memory of the cells of the immune system.
