The correct answer is: gaps left at the 5' end of the lagging strand

Telomeres are repetitive regions at the very ends of chromosomes found in eukaryotic organisms. The “problem” with telomeres is that the DNA  replication cannot be fully finished in each round which result in a slow, gradual shortening of the chromosome.  

Gaps at the end of lagging strand are formed because lagging strand is synthesized via Okazaki fragments (small DNA fragments). So, when replication fork during replication reaches the end of the chromosome, a short stretch of DNA does not get covered by an Okazaki fragment and consequently remains uncopied in each round of replication, leaving a single-stranded overhang.

Telomerase is an enzyme that solves this problem by extending the telomeres of chromosomes.

yKpoI14uk [10]

Lana concludes that all of the deer in a forest are members of the same (geosphere / ecosystem / species / hydrosphere) because they look alike and breed with one another. She observes how the deer (population / community / ecosystem / biosphere) interacts with trees, wolves, and other living things of the forest (population / community / species / geosphere).

Answer:

1.  Species

2.  population

3.  community

Explanation:

Given the available options. Here is the correct or full text that matches with the correct meanings.

anyanavicka [17]

Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would

- The amount of food increased or decreased

- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa

Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.

Sperm cells swim through liquid. Explain how a sperm cell is adapted to reduce friction as it swims.
Savatey [412]

Answer:

Long tail and narrow head.

Explanation:

A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.

Elanso [62]

Answer:

<h2>b) Anaphase II of meiosis </h2>

Explanation:

1. Meiosis is the process of cell division in which one cell is divided into four daughter cell, each contains equal number of chromosome, half the number of chromosomes as compared to parental cell.

2. In meiosis I, DNA duplication occurs but the sister chromatids are not separated, only homologous pair of chromosomes are separated, so this is called reductional division.

3. In meiosis II, chromatids are pulled apart and and are separated into different chromosomes, so it is called equational division. There is no DNA duplication in meiosis II.
