which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G
Answer: d. C-G
Explanation:
DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.

Scientists analyzed data collected over a period of years in a game reserve in South Africa to test the hypothesis that competition with lions limits the abundance of leopards in the same community. The game reserve encompasses a variety of habitats, from open grassland to wooded areas around rivers and streams. It contains most of the indigenous mammal species and an adequate availability of their prey. For the most part, the leopards and lions show similar habitat preferences in the reserve.
The mass of the average lion is about three times that of the average leopard. The scientists analyzed several factors that might influence the abundance of each population, including the sizes of the animals preyed on by each species
Size of Prey Animal Percent of Leopards’ Prey (±2SEx¯) Percent of Lions’ Prey (±2SEx¯)
Small 34 ± 2 3 ± 1
Medium 63 ± 3 23 ± 2
Large 3 ± 1 36 ± 4
Very large 0 38 ± 3
Because competition with lions might affect the population size of the leopards, the scientists also analyzed data on the lion and leopard population sizes in the game reserve (Figure 1).
Required:
Describe what scientists mean when they refer to an ecological community such as that shared by the leopards and lions.
Answer:
The correct answer would be - these are the ecological community that shows the interspecific competition.
Explanation:
In this ecological community, both predators lion and leopards are living together and by the given data and information it is evident that they both share the same habitat and they both depend on the same prey for their food.
This cause competition between both lion and leopard for food and habitat. Such competition or interaction is referred to as the interspecific competitions negatively impacted by the presence of the other because they will have less food.
Answer
An ecological community refers to all of the interacting populations in a defined habitat.

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight
A Spray irrigation
Furrow irrigation
Flood irrigation
Drip Irrigation
Answer: Furrow Irrigation (B)
Explanation:
Furrow irrigation
Salinization of the SoilThe accumulation of water-soluble salts in the soil is known as salinization. Excess salts inhibit crop growth by decreasing their ability to absorb water, making salinization a resource concern.Surface irrigation in which trenches or "furrows" are created between crop rows in a field is known as furrow irrigation. Furrow irrigation is done by laying down short parallel channels down the length of the field in the direction of the predominant slope.Furrow irrigation is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlightFor more information:

Which of the following biotic factors is associated with increasing the capacity of the organisms to move across fragmented landscapes? Patch size, connectivity,Patch shape, Distance from other landscape patches
Answer:
connectivity
Explanation:
Natural and anthropogenic alterations affect the landscape. The unmeasurable use of the land for farming, cattle industry, buildings, among many other activities, has caused a severe fragmentation in the original landscape that has been seriously affecting biodiversity.
Fragmentation occurs when a big extension is transformed into many different and smaller patches, separated by another type of cover. You can imagine, for instance, an area used for mono-culturing, which you can see as a homogeneous space of the same texture and color, and small green islands of original vegetation dispersed in this cropped area. These small islands are separated from each other by the crop.
These alterations produce patches or tesserae in the landscape. Patches are relatively homogenous areas with well-defined borders and environmental characteristics very different from those of the surrounding areas. These are like islands. You can think about patches or tesserae as the remaining pieces or units of the original landscape dispersed inside an affected bigger-sized area.
Fragmentation generates a significant loss of physical continuity between the different areas of the original habitat. It might negatively affect biodiversity by decreasing patch sizes, completely isolating them from each other, and increasing the border effect.
Many species can not survive if they are not in the original habitat. Probably they do not find enough food or shelter, or they are very exposed to predation. So they need to stay in the patch. Most of these species are not even adapted to living on the border of the patches. Eventually, fragmented areas can not support some population species that end by dying because they can not survive for a long time in that reduced place. Patches are not suitable to support too many species.
For these reasons, the connection between islands becomes so important. To allow species to move from one place to the other, interact with other species, reproduce, find food, shelter, avoid predation. In other words, survive. Connectivity is how the territory makes possible individuals flow or genetic flow, between the different tesserae.

What adaptation helps the pine tree reduce water loss?
leaves
thorns
Seeds in cones
Woody stems
Answer:
leaves
Explanation:
The needles of pines, like those of other conifers, are well-adapted for growth in dry environments. In particular, the outer surface of pine needles has a thick waxy layer, called a cuticle, which reduces evaporative water loss.
Answer: Option (A) leaves
Explanation:
Pine trees thankfully have needles, which are thin, waxy leaves that enable them to make food year-round. The waxiness of the needles helps evergreens not lose water to evaporation.

What is the purpose of hardening?
To eliminate all disease
To manage the population of endangered trees
To allow nursery plants to transition to the outdoors
To make sure that the trunk of the tree is as strong as possible before planting
Answer: To allow nursery plants to transition to the outdoors.
Explanation:
Hardening is a process in which the small seedling plants are exposed to the unprotected environment of the garden so that they develop some tolerance against those conditions. The small seedlings were earlier exposed to low water, sunlight, and wind conditions but for hardening they are kept at those areas of the garden where they experience harsh levels of these agents for a short duration and the duration is increased with routine so that plants can adapt the changes when they are planted outdoor or outside the care of garden. It is one of the gardening practices.

What are the similarities between the coastal oceans and coral reefs
Answer:A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral.
Coastal oceans are commonly defined as the areas from the shoreline to the outer edge of the continental margin. They connect the continents to the open ocean and serve as a link for transporting organic and inorganic, natural and anthropogenic material from land to sea.
Coastal oceans in tropical areas have similar characteristics to their temperate counterparts. ... Coral reefs are biologically diverse and rich habitats that occur in relatively nutrient-poor environments along coastlines. Areas that have too many nutrients often harbor too much algal growth to sustain coral growth.,
