The biogeochemical cycle has to do with the cycle of nutrients and elements in nature.
What is the biogeochemical cycle?The biogeochemical cycle has to do with the cycle of nutrients and elements in nature; they include the water cycle, carbon cycle, and nitrogen cycle.
The water cycle begins with the evaporation of surface water which is then condensed in the cloud and falls as rain.
The carbon cycle involves the combustion of fossil fuels, the calcification of shells of animals as well as the decay of organisms to release gaseous CO2.
The nitrogen cycle involves the nitrogen content of living things that is returned during decay to the earth as well the fixation of nitrogen by bacteria and also nitrification.

Propose an ecological solution that would protect the tiger species by maintaining the complex interactions within an ecosystem. Provide at least one strength and one limitation to this proposed solution.
Tigers have the ability to coexist with their own predators like brown bears, leopards, etc. In this condition, it is the risk that these predators may threaten the tiger species. Therefore, it is required to construct a special habitat for tigers where they get enough resources without any threat.
What is an Ecosystem?An ecosystem may be defined as a place or area where members of different species live together and interact with one another for the purpose of food, shelter, and space.
The strength of the above solution is that the population of tiger species will be maintained in near future, but the limitation is that here we provide an artificial habitat for the tiger. Now, it depends on them to reside naturally or not.

What are the 4 major groups of birds?
Answer:
Strisores — nightjars, frogmouths, and other nocturnal birds, along with diurnal swifts and hummingbirds.
Columbaves — turacos, bustards, cuckoos, pigeons, sandgrouse, and mesites.
Gruiformes — cranes, rails, crakes, Sungrebe, flufftails, and others.
Aequorlitornithes — shorebirds, flamingos, grebes, gulls, tropicbirds, penguins, and other waterbirds.
Explanation:
Answer: The four important group of birds are 1. Game Birds 2. Preying Birds, 3. Perching Birds and 4. Flightless Birds.
Game birds are good runners but they cannot fly long distances. Their wings are short and round, but legs are massive. The beaks are also strongly built. Males are aggressive. One male maintains a group of 3-4 females. Game birds include partridges, pheasants, quail, grouse and pea fowls.
Preying birds are predators. They kill mice and other smaller animals and eat them. They have very strong, hook-like beak. There feet have curved and pointed claw. Their vision is very sharp. Preying birds include vultures, kites eagles and falcons.
Perching birds constitute the largest group of birds. When they sit on a tree, their digit grasp the branch of the tree in such a way that they cannot fall off the branch. Baya, larks, swallow, bulbul, finches, house sparrow, weaver-bird, crow and magpie are some common perching birds.
Flightless birds can run but they cannot fly. Flightless birds are large-sized. They generally lack tail feathers. The keel of sternum is absent. Flightless birds include ostriches, rhea, emu, kiwi, and penguin. Ostrich is the largest living bird. It weighs about 157 kg. Ostriches are very good runners. They are found in Africa and Arabia. Rhea is found in South America. It is smaller than ostrich. Emu is found in Australia. It is smaller than rhea. Kiwi is found in New Zealand. It is Southern hemisphere (Antarctica). Their body is suited for diving and swimming.

Pandrug-resistant bacteria are defined by the bacterial strain, which is tolerant to all antimicrobial drugs currently available.Non-susceptibility to all drugs in all antimicrobial categories was termed Pan Drug Resistance(PDR). Resistance strategies are easily adopted by PDR microbes. Pan-drug-resistant Acinetobacter baumannii, pan-drug-resistant Klebsiella pneumonia, and pan-drug-resistant Pseudomonas aeruginosa are only a few examples.Because of their high vitality, colonization rate, and antibiotic resistance, these bacteria are frequently transmitted to patients.To learn more, refer:

A fly has two alleles for the color of its eyes. The green allele is recessive, and
is represented by q. The blue allele is dominant, and is represented by p. If 44
of 100 organisms are green, what is p?
Homozygous dominant+ Heterozygous + Homozygous recessive = 1
↓↓↓
p²+ 2pq+q=1
A. 0.66
B. 0.56
C. 0.44
D. 0.34
Answer: D. 0.34
Explanation:
The Hardy-Weinberg Principle is a theory in biology that represents populations of organisms that don't experience any changes in genotypic frequency from generation to generation. These populations must meet the following conditions:
No genetic mutationsCompletely random matingNo gene flowNo selection (natural or artificial)An infinite population sizeIf a population meets these criteria, its genetic and allelic frequencies will remain constant and the population will be in Hardy-Weinberg Equilibrium. However, it is not possible for this to occur in nature, because at least one condition will always be violated in natural populations.
Hardy-Weinberg EquationsThere are two important equations to use when doing problems like this. The first is p + q = 1. It represents the allelic frequency of the population.
p = the frequency of the dominant alleleq = the frequency of the recessive allele
The second equation is p² + 2pq + q² = 1, which shows the predicted frequencies of the three possible genotypes.
44 of our 100 organisms are green, and we know that to be green, they must have a homozygous recessive genotype (gg). That means that the frequency of homozygous recessives (q²) = 44/100 or 0.44. Since we have q², we can just take the square root to find q.
[tex]\sqrt{q^2}[/tex]= [tex]\sqrt{0.44}[/tex]
q = 0.66
Now, we can plug q into our first equation, p + q = 1.
p + 0.663 = 1
p = 0.337, or about 0.34
To make sure these are right, we can plug them into the Hardy-Weinberg equation to check!
p² + 2pq + q² = 1
(0.34)² + 2(0.34)(0.66) + (0.66)² = 1
0.1156 + 0.4488 + 0.4356 = 1
1 = 1
