Which of the following are enzymes involved in DNA replication? helicase DNA polymerase ligase all of the above
Answer:
All of the above
Explanation:
Helicase separates the two DNA strands to prepare them for replication. Without helicase, no replication would be possible, as the amino acids would not be accessible to be copied.
DNA polymerase is on the front lines of replication, directly copying the leading strand all at once. Because the lagging strand cannot be replicated in the same way due to its 3' to 5' orientation. DNA polymerase replicates in fragments while other enzymes fill in the gaps.
Ligase binds these fragments together to form a complete strand.

According to the evidence scientists have gathered, whales and hippos are more closely related than whales and fish. Describe the types of evidence a scientist uses to infer whether two species such as whales and hippos share a common ancestor.
The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.
What is evolution?
Evolution can be used to describe descendence from a common ancestor of two or more species.
The presence of homo-logous structures is indicative of common ancestry between different species.
These homo-logous structures can be observed during the embryo stage of organisms and the observation of the fossil record.

A. It produces body cells.
B. It causes alleles to go bad.
C. It prevents genetic problems.
D. It produces gametes/ sex cells.
Answer:
D. It produces gametes / sex cells.

Meiosis is a reductions division, so the source of the sex cells will produce the gametes, undergoing meiosis. The gametes will have half the number of chromosomes in a human body (23).
Why would it be useful to extract and observe DNA?
Answer:
The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs. It is also essential for carrying out forensic science, sequencing genomes, detecting bacteria and viruses in the environment and for determining paternity.
Explanation:
Explain the trigger that starts the breakdown of glucose.
Your liver releases stored glucose (glycogen) into circulation after being prompted by glucagon to transform it into a usable form.
What is a breakdown of glucose?Glycogenolysis is the name of this process. Additionally, glucagon might stop your liver from absorbing and storing glucose, keeping more of it in your blood.
A metabolic process called cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration.
The amount of insulin secreted by the pancreas determines how quickly glucose and carbohydrates are used. With the exception of liver and brain cells, the quantity of glucose that may diffuse in cells is often limited.
Therefore, the liver releases stored glucose (glycogen) into circulation after being prompted by glucagon to transform it into a usable form.

Grassland ecosystems in Texas have evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a prescribed burn. What natural processes are the biologists attempting to imitate
Answer:
Succession
Explanation:
The biologists were attempting to imitate succession.
Succession refers to a gradual change to the structure and species composition of a community over a period of time.
A newly colonized environment such as a bare rock forms a community is said to be in primary succession. Thereafter, the structure and composition of the community keep changing until a relatively stable community, otherwise known as climax community, is established.
Secondary succession happens when a disturbed community tries to regain its original dynamics in terms of species composition and structure. A climax community is often less diverse than a community that is still in active succession.
Hence, the biologists were attempting to imitate succession by burning/disturning a relatively stable, less diverse climax community of grassland in order to realize a more diverse community that will undergo secondary succession.
Answer:
Succession

What is Restriction site?An isolated bacterial protein known as a restriction enzyme cleaves DNA at sequence-specific locations to create DNA fragments with a known sequence at each end.
For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
There are at least 3,000 restriction enzymes, and they are all really cool. Each of these enzymes snips a certain DNA sequence, regardless of whether the DNA comes from a mouse, a bacterium, a fungus, or a human.
