Answer:
Actually, they have all of these features
Explanation:
Sister chromatids are replicated chromosomes formed during DNA replication at the Interphase stage. Since one is a replica of the other, they are the same in lenght, alleles content and every other aspect. They are joined together at the centromere.
Sister chromatids are separated from each other into each daughter cell at the Anaphase II of meiosis II and Anaphase of mitosis specifically. Hence, they remain attached to one another by their centromere until they reach Anaphase. Every chromosome contains the telomere at their end region and it plays a vital role in ensuring that neighboring chromosomes do not join.
Answer: mechanical weathering
Explanation:
Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.
Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.
Water is an important agent of mechanical weathering, in either liquid or solid form.
Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.
There's a bunch of examples.
For example, hairlines. A widow's peak is a dominant trait over a straigh hairline.
Or dominant hand type. Right hands are dominated over left hands.
Or hair types. Curly hair dominates straight hair.
If you google it, you'll get a lot more examples.
Answer:
If a neurotransmitter attaches to a ligand-gated channel and creates a potential that causes the inside of the excitable cell membrane to become less negative, and this potential travels only a short distance before dying out, it is considered to be a <u>Graded or local potential</u>
Explanation:
<em>Graded potentials, also known as local or generator, are generated by an excitatory neurotranmitter, usually a ligan gated channel</em>, they occur at a localized place on the cell and their potentials are smaller (from 1-50mV) and its magnitude depends on the strength of the stimulus.
I hope you find this information useful and interesting! Good luck!
Answer:
The correct answer is - option C. Deep.
Explanation:
The river with a narrow river channel found in shallow depth rivers that show relatively faster water flows than the deeper river that are slow in the water flow. In the shallow rivers sediments found in suspended mode and transported to the sea or delta and deposited there.
In deeper rivers, the sediments found deposited in the rivers which is helpful for the fishes for their nutrients as they feed on these sediments.
Thus, the correct answer is- option (C).
