Answer:
C. a delay in DNA polymerase beginning synthesis
D. a longer total time to replicate DNA
Explanation:
DNA primases are RNA polymerases that play an active role during DNA replication by catalyzing the synthesis of short RNA sequences or 'primers' that are complementary to a single-stranded piece of DNA (i.e., to the DNA template). Primases are continuously required at the DNA replication fork before DNA replication can occur. Moreover, DNA polymerases always require a pre-existing primer sequence to initiate DNA chain elongation, thereby it is expected that an inefficient primase delay the DNA replication process and DNA polymerase activity.

The small finches on the Galapagos islands lived on islands with slightly different habitats. How did these varied habitats affect the evolution of the finches on different islands?
Adaptations - Darwin's Finches. Here are some adaptations of particular finches and the finches as a whole. ... The birds with bigger beaks survived, and the rest adapted by having developed strong and big beaks, or developed beaks that allow them to use tools to reach their food.
Hope it helps...
These varied habitats results in adaptive radiation which is responsible for evolution of the finches on different islands.
What is evolution?"Evolution is change in the heritable characteristics of biological populations over successive generations."What is adaptive radiation?"Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available."The small finches had to change its type of nutrient(eating seeds, small worms, etc.) in order to survive on the varied habitats of island. This results in their evolution.
Hence, adaptive radiation occurs due to varied habitats.

Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are more number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls in it. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes that increases its weight.
Which definition is the best for semipermeable membrane?
"The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through"
Answer:
Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.
Explanation:
The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through.
Label the parts of the microscope shown in the picture below using the following terms: coarse adjustment knob, eyepiece (or ocular lens), fine adjustment knob, light condenser and iris diaphragm, objective lenses, stage
Answer:
A is the eyepiece (or ocular lens), B is the objective lenses, C is the iris diaphragm, D part is refers to light condenser, E is the location of fine adjustment knob and F is the location of coarse adjustment knob.
Explanation:
A is the eyepiece (or ocular lens), B is the objective lenses, C is the iris diaphragm, D part is refers to light condenser, E is the location of fine adjustment knob and F is the location of coarse adjustment knob. All these parts are the important parts of microscope which has a specific function in the microscope. Without one of these parts, we can not see the microbes in the microscope.
After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scoprtion species that lived 255 million to 460 million years ago was 2.5 meters long. Which of the following conclusions is supported by this information?
A. scorpions living today have increased their numbers since they first appeared
B. scorpions in the fossil record are smaller than their descendants are
C. scorpions have changed as a result of natural selection
D. scorpions do not appear in their original state in the fossil record
Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.

i) Describe the function of stomata.
Answer:
Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
Explanation:
the main fiction of stomata is to open and close the pores in the leaves for an exchange of gases.
it allows the plants to take in carbondioxide and gives out oxygen for photosynthesis.

10.What is holozoic nutrition?
Answer:
1. Digestion helps to break down the food into simple, soluble form.
2. Name the process by which absorbed nutrients are utilized by the body?
Ans. Assimilation is the process by which absorbed nutrients are utilized by the body.
3. Where does initial digestion of protein take place?
Ans. Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
4. Where is the water absorbed from undigested food in the digestive system?
Ans. Water from the undigested food is absorbed mainly in the large intestine.
5. Name one animal that lives on liquid food only.
Ans. Mosquito lives on liquid food only. They rely on human blood for their food.
6. The process of taking in food into the human body is called ingestion.
Ans. True.
7. The alimentary canal stretches from mouth to anus.
8. What is rumen?
Ans. Rumen is the largest compartment of the stomach of a ruminant in which cellulose is broken down by the action of symbiotic microorganisms. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.
9. Which animals are called ruminant?
Ans. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach, they have four. Of the four compartments, the rumen is the largest section and the main digestive centre.
10.What is holozoic nutrition?
Ans. Holozoic nutrition is a method of nutrition that involves the ingestion of some complex organic substances that may be in the solid or the liquid state.
This fly has 14 chromosomes in its cells.7 maternal chromosomes and 7 paternal chromosomes.Assume you are a microscopist viewing this fly cells that are undergoing meiosis. Conclude the number of chromosomes/chromatids at the end of meiosis 1 as well at the end of meiosis 2
Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.
