Answer:
Larger habitats support populations with higher carrying capacities. Higher quality habitats support populations with higher carrying capacities. There is no difference in population growth rate between large and small habitats. Some major threats to biodiversity are: Habitat destruction/Deforestation, Introduced and invasive species, Genetic pollution, Over exploitation, Hybridization, Climate change, Diseases, Human overpopulation. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. If resources are destroyed, the ecosystem will not be able to support a large population. This causes the carrying capacity to decrease.
Carrying capacity could be reduced if each individual within the species consumed less from the environment. Think about humans: if every human needs a four car garage and a large house, the planet can sustain fewer humans than if each human lived in a studio apartment and traveled using a bicycle. It would take 1.75 Earths to sustain our current population. If current trends continue, we will reach 3 Earths by the year 2050. It is beyond dispute that the modern industrial world has been able to temporarily expand Earth's carrying capacity for our species. As Nordhaus points out, population has grown dramatically (from less than a billion in 1800 to 7.6 billion today), and so has per capita consumption. Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity. Sustainable agriculture practices support integrating biodiversity in various ways including in terms of diversity of crops, traditional agriculture techniques to control pests and increase productivity as well as ensuring that farmed land is made up of a diverse mix of grazing land, crop land, orchards, wetlands and more.

Hope this helps :)
Because it's vital to the survival of all species, not just human, that we have resources such as food and water. Also that those resources be clean and healthy. We also need to manage resources such as oil to make sure there are fewer wars like the ones happening in the Middle East. If you need anything else just message me.
There may be some strains of bacteria that are naturally resistant to these antibiotics, or there may be some that mutate to become resistant. This means that as antibiotics are used more and more, those that can be killed using the antibiotics die out, but those that are resistant will remain, and will reproduce. Over time, it will be the resistant species that predominate.
An animal's physiology can indicate it's diet based on what the animal's body can handle processing. For example, animal's with strong bones and teeth can break down food that is tough to eat, this helps obtain energy alot quicker. For instance, giraffes have long and slender necks that are perfect for reaching up to trees. The giraffe's diet would consist of vegetation located in high levels.
Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
