What is cladistics?
OA. The comparison of species based on common behavioral
characteristics
B. The comparison of species based on their geographic range
C. The comparison of species based on the presence or absence of
ancestral traits
D. The comparison of species based on common physical
characteristics
The comparison of species based on common physical characteristics Thus, the correct option is D.
What is cladistics?Cladistics is a method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.
A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.

Its main function is the packaging, modification and secretion of proteins. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane or secretion. They also take part in the transport of lipids and the formation of lysosomes.Enzymatic processing and post-translational modification occur near the membrane surface in Golgi bodies, e.g. phosphorylation, glycosylation, etc.Golgi apparatus is the site for the synthesis of various glycolipids, glycoproteins, etc.#SPJ2
What is a spring tide? When and why does it occur?
Answer:
Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That's when lunar and solar tides line up and reinforce each other, making a bigger total tide.
A spring tide occurs when there's a new or full moon. Because it follows the moon's lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.

Why some plants like a citrus plants bear thorn ?
PLEASE HELP MEEE WITH THIS QUESTION
Answer:
2) 6) 3) 4)
Explanation:
The following factors will affect the current oxygen and carbon dioxide levels.
Burning fossil fuels increases the output of CO2 outside of organisms that perform cellular respiration-CO2 is a green house gas and is a cause of global warming. burning fossil fuels will increase CO2 in the atmosphere which cannot be balanced by the natural sinks like forests and oceans.Deforestation reduces the number of photosynthetic organisms able to produce oxygen and consume carbon dioxide. Deforestation causes habitat loss and hence a large amount of tree cover is lost which will reduce the amount of oxygen generated and CO2 absorbed.When land is deforested for agriculture, the photosynthetic productivity of crops is not equivalent to the forests being replaced. This is so because forests have large trees and plants which have a greater photosynthesis capacity however new crops which are small and are removed annually are not able to compensate for the loss of large forest trees.learn more about oxygen and carbon dioxide levels here:

Why is there competition in nature?
A. Living organisms are influenced by abiotic factors.
B. Ecosystems are composed of habitats and communities.
C. There are more living things than there are resources to support them.
D. Environments are constantly changing as organisms interact.
Answer:
c
Explanation:
Competition exists in nature due to the limited availability of resources compared to the abundance of living organisms. This creates a struggle for survival and dominance among species, leading to an ongoing process of natural selection. Thus, correct option is C.
Because there are more living things than there are resources to support them, competition is a natural phenomenon. There is a limited supply of food, water, shelter, and other survival-related essentials in the Earth's ecosystems. As a result, in order to meet their demands and ensure their survival, organisms must contend for these scarce resources.
This rivalry is essential to the process of natural selection because it increases the likelihood that organisms with beneficial characteristics or adaptations will survive and pass on their genes to the following generation. Because only those with the strongest adaptations flourish in a certain habitat, this eventually drives the evolution and specialization of species.

Explanation:
hope it is helpful
Answer:
Explanation:
: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.
