Answer:
. A euglena survives on its own because it completes all life functions. A white blood cell cannot survive on its own because it is just one cell.
Explanation:
. A euglena survives on its own because it completes all life functions. A white blood cell cannot survive on its own because it is just one cell because A Euglena is a unicellular organism that can perform photosynthesis and complete cell activities. They live in fresh water, have eyespot, can excrete and have flagella for movement which are cellular activities
But a white blood cell cannot survive because it is one cell because it is produce from bone marrow and is a part of the immune system and work with other networks in the body system to fight against body infections.
Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.

f. obtaining
energy
These three
traits definitely standout as a challenge for every living creature in the ecosystem.
In Darwin’s Natural Selection Survival of the fittest: being fit is one
category in order to survive the wild, in other words, being flexible. Reproduction
is battle royale in both humans and animals, even for plants too. Why? Because
the ecosystem changes, the weather changes, the food chain is a combat to chase.
Some can’t even reproduce due to hereditary or physical causes. Energy is as
important as living. If plants can make their own food how about the carnivores
and the omnivores. Food is a challenge. Structure is sustaining the capacity
and ability to hunt and survive. Important and a by-product of obtaining
energy.
Answer:
If the light was artificial, the plant could survive if it has water. You could use a lamp
Explanation:
write it in your own words:
"In humans, five days after the fertilization, the blastocyst performs zona hatching; the zona pellucida degenerates and decomposes, to be replaced by the underlying layer of trophoblastic cells. The zona pellucida is essential for oocyte growth and fertilization."
The zona pellucida supports communication between oocytes and follicle cells during oogenesis; protects oocytes, eggs, and embryos during development, and regulates interactions between ovulated eggs and free-swimming sperm during and following fertilization.
