Answer:
A
Explanation:
Asexual reproduction is a type of reproduction where offspring comes from a single parent.
B is incorrect because asexual reproduction requires only one individual, while sexual reproduction requires two.
C is incorrect because mutation rates are not lower in sexual reproduction than in asexual reproduction.
D is incorrect because lots of single-celled organisms, like bacteria, reproduce asexually.
True, Chordates are animals in Phylum Chordata.Chordates include all of the vertebrates, in which the notochord develops into a backbone, as well as some invertebrates. Invertebrate chordates include tunicates and lancelets.
Answer:
1. E.coli
2. Intestinal tract
Explanation:
E.coli bacteria are useful to humans when they live in the large intestine of humans. The large intestine is an important digestive structure as it is important for the reabsorption of the nutrients.
The E.coli living in the intestine use the available digested nutrients and synthesises the vitamin B and K which are absorbed and utilised by the human body.
Thus, E.coli and Intestinal tract is correct.
Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two. But, to remain viable and competitive, a bacterium must divide at the right time, in the right place, and must provide each offspring with a complete copy of its essential genetic material. Bacterial cell division is studied in many research laboratories throughout the world. These investigations are uncovering the genetic mechanisms that regulate and drive bacterial cell division. Understanding the mechanics of this process is of great interest because it may allow for the design of new chemicals or novel antibiotics that specifically target and interfere with cell division in bacteria.
I think this might be the answer...
Answer:
Option - E is the same distance from A and B.
Explanation:
Perpendicular bisector can be understood by this explanation:
If line n is intersected by line n at the center of line n
, then line m is the perpendicular bisector of line n
There are 4 right angles formed due to this perpendicular bisector around this mid-point
∵ Line CD ⊥ of segment AB
∴ Line CD intersects segment AB at the middle point of AB
∵ Line CD and segment AB intersected at point E
so, E ∈ AB and E ∈ CD
⇒ Point E is the mid-point of line AB
⇒ E is the same distance from A and B.
Thus, the correct option is - E is the same distance from A and B.
