i)  X is a tree that produces glucose by the process of photosynthesis whilst Y is a fungi that grows on it

together they are called symbionts

a symbiont is an organism that is very closley associated with another usally larger organism (host)

ii) symbiotic relationship: the interaction of symbiont species and a host species

there are two types of symbiont

1)ectosymbionts : live outside their host cells

2)endosymbionts : live outside of their host's cell

ii)There are 6 symbiotic relationships one example is parasitism which has a negative effect on the host but a positive effect on the symbiont an example of parasitism include lice and fleas

Oxygen is combined with the carbon atoms left from the glucose molecule.

Explanation:

Answer:

B.

Explanation:

Answer:

I'm pretty sure it is because oxygen is a single atom and air has multiple atoms

Answer:

Here-

Explanation:

Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.

Air isn't exactly pure its got all the gases mixed together, but when we breathe oxygen is pure because nothing else can make oxygen, its just O.

Air can still be air if it doesn't have carbon dioxide in it. It can still be air without water vapor. Also oxygen is a pure element on the periodic table.

Hope this helped. :))

Answer: Homeostasis is a resistance to change.

Explanation: There are many other examples of homeostasis in biology, like the pH of blood and the concentration of ATP in a cell.

The muscles begin shivering on a cold, snowy day is n example of homeostasis. So, the correct option is (D).

Homeostasis is defined as a state of stable internal, physical, and chemical conditions maintained by living systems that are optimal functioning conditions for the organism and includes many variables, such as body temperature and fluid balance, some being kept within pre-determined limits.

Homeostasis is the maintenance of optimal conditions for enzyme action throughout the body, as well as all cell functions which is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, homeostasis include the control of: Blood glucose concentration. Some example of homeostasis is the muscles begin shivering on a cold, snowy day.

groundwater is being cycled

Answer:

by absorbing water and then releasing it slowly.

Explanation:

Answer:

Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage and braking action lowers flood heights and reduces erosion.

Why are wetlands referred to as "biological supermarkets"? pt.2 for edn2020

Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings. The holding capacity of wetlands helps control floods and prevents water logging of crops. Preserving and restoring wetlands together with other water retention can often provide the level of flood control otherwise provided by expensive dredge operations and levees. The bottomland hardwood- riparian wetlands along the Mississippi River once stored at least 60 days of floodwater. Now they store only 12 days because most have been filled or drained.

Answer:

Explanation:

Evolutionary psychology seeks to understand the adaptive, evolved nature of humans by considering the forces of natural selection that gave rise to it. Individual humans also exhibit maladaptation, however, and some of the variation in maladaptive conditions is heritable. An evolutionary perspective can shed light on these phenomena too. Recent work suggests that developmental imprecision importantly affects the fitness of organisms and some of the genetic influences have been identified. Both theory and evidence that developmental imprecision underlies human cognitive maladaptation has begun to accumulate, although the manner in which the developing brain is affected remains largely unknown.

Birdhouses are a fantastic way to add shelter to a bird-friendly backyard, but if no birds are nesting in the houses, then how do you make them come? There can be a wide range of difficulties with birdhouses, but there are also easy ways to fix each problem to make the houses more attractive to nesting birds. If birds aren’t using your houses, check these common problems and solutions to be a better bird landlord.

No Birds Even Look at My Birdhouses

It may be that there are no cavity-nesting birds in your yard. Only certain species of birds will use houses, and if you know which birds those are, you can add feeders, water features, and shelter to make the yard more attractive to those species. As they get more comfortable with your yard, they will start to check out the available nesting sites, including birdhouses.

Birds Build Nests Before My Birdhouses Are Ready

Spring Flowers in Snow

If you’re waiting until spring flowers bloom to put up birdhouses, it may be too late to attract the first nesters. Early-nesting birds, however, may still investigate the house for additional broods later in the season. Putting houses up earlier can help attract the earliest nesting species and ensure the houses are ready for residents. Ideally, have houses ready to go in late winter to be available for every nesting bird.

Birds Ignore the Birdhouse to Nest Elsewhere

Unique Birdhouses

Some bird species can be very particular about their preferred houses, including floor dimensions, house shape, and other details. Finding birdhouses that are specially designed for the species you want nesting nearby is the best option for meeting their needs with an appropriate house. Be sure you use houses of the right dimensions and with the proper entrance hole size to suit the birds in your yard.

Birds Build Nests Lower Than My Birdhouse's Height

Tree Canopy

Where you mount a birdhouse is just as critical as the size and shape of the house itself. Some birds will use higher houses, while others prefer houses closer to the ground. Birds nest at different heights and have different preferences for whether the house is mounted on a pole or tree, or if it can be hung. Understanding birds’ preferences can help you position birdhouses properly.

Birds Never Reuse Old Nests

Old Bird Nest

Most nesting songbirds will not reuse old nests, though they may reuse a small amount of the nesting material to build a fresh nest. The best option is to clean out birdhouses after every brood has fledged so the house is clean and clear for another pair of nesting birds to use. This also reduces the risk of dangerous contamination from old feces, feather mites, or insect infestations in an old nest.

My Birdhouse Is Threatened by Predators and Invaders

Cat on a Birdhouse

Birds always look for a safe place to raise their nestlings. Adding safety features such as baffles or guards to a birdhouse will help protect brooding birds. Perches should be removed, and the house design should include drainage and ventilation for safety and comfort. Keep cats indoors and take steps to discourage feral cats and other unwelcome birdhouse predators from your yard.

Larger Birds Use My Small-Bird Birdhouse

European Starling

An inappropriate entrance hole can admit larger birds such as house sparrows or European starlings to a birdhouse, crowding out more desirable residents. Larger birds may even kill hatchlings or brooding adults, but a properly sized entrance hole will keep out larger species while admitting other birds. If the hole has gotten bigger over the years, there are easy ways to fix it to keep larger birds from entering.

My Beautifully Painted Birdhouse Isn't Being Used

Paint Brushes

Paint can be toxic to birds, and painting a birdhouse should be done carefully so as not to endanger adults or nestlings. Exterior paint should be camouflaged to help protect the house from predators and other invaders, as well as to help control the interior temperature of the house. Avoid paints with glitter or other quirky accents, and opt for simple, understated designs to appeal to more cautious birds.

I Want to Take My Birdhouses Down in Winter but Birds Are Still Using Them

There can be a wide range of difficulties with birdhouses, but there are also easy ways to fix each problem to make the houses more attractive to nesting birds.

Some birds do not make nests at all and instead lay their eggs in a simple scrape in the ground. Other birds construct nests from natural materials, such as grass, leaves, mud, lichen, and fur, or from human-made materials like paper, plastic, and yarn.

Birds don't vigorously tear up mouthfuls of grass, pluck out their own feathers, pull threads out of outdoor rugs, or peel the screens off windows for no good reason.

The time for incubation varies widely from species to species. Roughly speaking, small songbirds take between 10 days and 2 weeks to hatch and the same amount to fledge. Larger birds such as woodpeckers may take 3 weeks to a month to fledge.

Solar energy is expensive and solar energy works during every season, however the productivity drops, hence option A is correct.

The fact that solar energy might be temporarily disrupted by weather is one of its drawbacks. The amount of electricity you create is less on cloudy days. However, the cold has little impact on output.

Any energy produced by the Sun is referred to as solar energy. Direct or indirect human usage of solar energy is possible.

Solar energy is captured and transformed into power by these solar panels, which are installed on a roof. Solar water heaters and home heating are two common uses for solar energy.

Therefore, solar energy can also be used for cooking and as a source of power for technological equipment.
