<h2>Sea star </h2>
Explanation:
In the given example sea star played the role of keystone species
- Robert Paine actually coined the term keystone species to describe the effect that the sea stars had on biodiversity in this community
- Keystone species are those species which are least abundant but play a governing role to decide the structure and function of community
- Loss of keystone species in a community can lead to disturbance in structure and function of a community and it cannot be recovered by other species
The very first one is the answer-
Abiotic changes have the ability to dictate biotic ones. This can be caused by humans.
For example: an abiotic thing can be an element like water. If the water in a lake gets poisoned by chemical compounds, this is an abiotic change. However, since the lake is now poisoned it’ll likely harm or even kill fish, bacteria, algae, and any other wildlife living within the lake. It doesn’t stop there though, without the lake surrounding animals won’t have clean water to drink, they can now die from either the poisoning, dehydration, or starvation if they lived off of the aquatic life from the lake.
If a cell has a diploid number 2n=46, then how many chromosomes does it contain?
46 total chromosomes
How many pairs of chromosomes?
2n/2 = n = 23 pairs
How many chromosomes would you find in a haploid cell from this organism?
haploid cells equal 1/2 (2n) = n = 23 total chromosomes
Mereka tergolong dalam kelas yang sama, yaitu kelas mamalia
Kelas mamalia memiliki ciri - ciri sebagai berikut :
- Hampir semuaBereproduksi dengan cara melahirkan
- Merupakan binatang yang menyusui
- Bernapas dengan paru - paru
