In physics, what is a black body?
Answer:
Blackbody, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena.
Birds display a wide variety of courtship behaviors. Which behavior is also a territorial behavior?(1 point)
creating a bower (arch) with interesting objects and defending it from rival males
flashing feathers to show their health and grooming abilities
dancing and calling on a lek (communal ground) with other males, competing for female attention
singing a particular song to help potential mates hear them
Answer: The correct answer is "creating a bower (arch) with interesting objects and defending it from rival mates".
Explanation:
Just took the quiz.
creating a bower (arch) with interesting objects and defending it from rival males is a territorial behavior.
What is Territorial behavior?Any defended area is referred to as a "territory," and most birds are territorial (in the sense that they defend some area, even if it's merely a nest site), at least for a portion of the year.
When a territory is defended, the "owner" has access to one or more resources (or access to resources of higher quality) than they otherwise would. According to what resource (or resources) is (are) being protected, territories can be categorized.
Type A territory, or the area where mating, nesting, and feeding take place (such as courtship, mating, nesting, & foraging).
Therefore, creating a bower (arch) with interesting objects and defending it from rival males is a territorial behavior.

The population in a 50 square mile area is 200 people. What is the population density?
Answer:
[tex]\rho _{population}=4\frac{people}{mi^2}[/tex]
Explanation:
Hello.
In this case, since the population density is computed by dividing the amount of people by the space (area) where they are in:
[tex]\rho _{population}=\frac{people}{area}[/tex]
For 200 people living in a 50-mi² area, the population density is:
[tex]\rho _{population}=\frac{200people}{50mi^2}\\\\\rho _{population}=4\frac{people}{mi^2}[/tex]
It means that 4 people live per square mile area.

In the natural selection simulation we set the fitness of rr individuals to 0. Why does the r allele persist in the population?
Answer:
In the clarification section elsewhere here, the definition of the concern is mentioned.
Explanation:
The notion of fitness seems to be the basic phenomenon of Fisher. Fitness is a dynamic term since it is the calculation by a person in his lifetime of the cumulative production of viable progeny. The fitness of an organism is zero even though no offspring is created. With a growing life span as well as the amount of order to promote innovation, flexibility increases. Members of an organization that are very well-adapted to that certain range of environmental factors have had a benefit in the mechanism of selective breeding over others who might not be as possibly the best adapted. The benefit falls throughout the form of genetic diversity and longevity. Those people who are much more able to easily find and use food supplies, for example, would live considerably longer and have more offspring than someone who is less reliable at seeking food. Inherited features that increase human fitness are then passed on to their descendants, thereby providing this very same value to the descendants. The disappearance of fewer adapted varieties seems to be the most drastic alternative. Unless the best-adapted variant doesn't adjust even though it is as when the optimum balanced local, so for the ideal characteristic, less drastic will delete both-new variant.Since less drastic selection has become too inadequate to aggressive edge mutations, the aggregation of missense mutations will happen and even the outcome would be a progressive deterioration of genomic integrity. If it maintains you prolonged enough, this should contribute to disappearance for certain species; nevertheless, the subsequent widespread presence of the deleterious mutations just seems like such a genome would then inevitably also contribute to backward mutation incidence. Extinction could result if the intense choice has become too high for the entire world, because if the world is saved in time.WHICH LEVEL OF PROTEIN STRUCTURE MUST BE INVOLVED IN FORMING THE ACTIVE SITE

Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

Meristamatic cells of onion root tip are displayed in the picture. This renders the most desirable and suitable raw material to study the different stages of mitosis.
What are meristematic tissue?A meristem is a particular kind of tissue that can be found in plants. It is made up of cells that have not undergone differentiation and are able to divide. Meristematic cells have the potential to differentiate into all of the other types of tissues and organs that can be found in plants. These cells will continue to divide until they reach a certain point, at which point they will begin to differentiate and will no longer be able to divide.
Additionally, meristematic tissue is responsible for the generation of secondary tissues like wood and cork. Both primary growth (expansion) and secondary growth (thickness) contribute to the plant's overall development.
Apical meristems are the cells that are responsible for the growth of the plant's primary body as well as the extension of its roots and shoots. Because they are the cells that are responsible for secondary growth, also known as an increase in stem girth and thickness, lateral meristems are also referred to as secondary meristems.

Answer and Explanation:
Variable: dissolved oxygen
Title: Oxygen variation as a water quality indicator.
Purpose: To study how dissolved oxygen varies with depth
Hypothesis: The percentage of dissolved oxygen will decrease as depth increases.
Procedure/Method:
Selection of sampling spots, according to the morphometry of the lake, different depth, water currents inputs and outputs, aquatic vegetation, and lake type of use. In each spot water samples will be taken using a Niskin bottle. The sample will be taken from different depth: 5 meters deep, 10 meters deep, and 15 meters deep (photic zone). Dissolved oxygen (DO) will be measured in each sample, by using a multiparameter sensor. In a field sheet to evaluate the parameter, the %DO by site and depth will be recorded.Observations:
%DO in each site and depth will be recorded in order to analyze how it varies with depth.
Data analysis:
According to different indicators of water quality in a lake, the observed %DO will be compared and analyzed to evaluate the sanity state of the lake water. Example of valuation scale,
NORMAL index: Oxygen concentration in the water column is found to be sufficient for the fish survival
REGULAR: Decrease in oxygen concentration at greater depth, values below saturation in the background
CRITICAL: Null oxygen concentration in all or part of the column profile of water. Probable fish mortality events.
According to the taken data, observations on the study site will be taken, such as the variation in oxygen concentration as it gets deeper, until reaching hypoxia level, where fishes can not survive. Data can be presented in tables and in graphs, in both cases comparing sampling sites and depth, making a focus on the valuation scale.
Conclusion:
Association of the oxygen variation with the sanity state of the lake, microbiology decomposition processes at different depths, eutrophication state, among others.

If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival?
Answer:
would increase
Explanation:
The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.
