11. Liquid methane has a heat of vaporization of 122 calories per gram (cal/g). Compare the
effectiveness of liquid methane and water for evaporative cooling.
Answers
Answer:
Water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.
Explanation:
Since the heat of vaporization of water is 540 calories per gram and that of liquid methane is 122 calories per gram, for each gram of the water evaporated, 540 calories is lost while for each gram of liquid methane evaporated, 122 calories is lost.
Since a higher heat loss would result in a higher temperature drop, water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.

Explain how meiosis results in UNIQUE cells.
Answers
Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.
Meiosis is the process such as:
Meiosis occurs in the reproductive cells of humans. Meiosis transmits genetic information from parent to offspring. Meiosis is the characteristic feature of sexual reproduction. The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.
Thus, meiosis always results in new variations and creates genetic diversity.

When completing this exercise, it may be useful to refer back to Labs 10-12 for information about living primates. In 2009, a new fossil species, called Darwinius masillae, was identified in Germany, represented by a nearly complete skeleton nicknamed Ida (depicted on p. 387 of your lab manual). It lived around 47 mya. It had a small brain, short protruding snout, large eyes, and postorbital bar. Its diet probably included a lot of fruit and leaves. It did not have a dental comb. It had nails instead of claws and was probably an arboreal quadruped. Researchers disagree about whether the fossil is more similar to living haplorhines (tarsiers, monkeys, and apes) or more similar to strepsirhines (lemurs and lorises). The skeleton is about 23 inches (58 cm) long including the tail, and has a body length of about 9 inches (24 cm) without the tail. Describe at least two features that Darwinius shares with living haplorhines.
Answers
Answer:
short protruding snoutlarge eyesIt had nails instead of clawsAbsence of dental combLong tailExplanation:
Haplorhines and Ida share the following characteristics:
- Both of them have plane nails in their fingers instead of claws. Nails are useful while eating and grooming. They might be necessary for defense too.
- They have a short snout, which is the cause of a poorly specialized olfactive perception.
- Neither of them has the dental comb characteristic of strepsirrhines.
- Eyes are big, located in the frontal area of the skull, and facing front. Vision sense is very developed. They have binocular vision, which allows them to calculate distances.
- The long tail is shared by both groups. Used during motion, to equilibrate, to hold, or grab.

Suppose all the alleles on on the left and right chromosomes switched places but kept the same order. Would the organism be different? Why or Why not?
Answers
Answer:
No
Explanation:
The chromosome will stay the same organism.
The organism would be same in both homogenous and heterogenous chromosome . Therefore, switching the alleles won't change the organism if order is maintained.
What is chromosome and its type ?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
An organism is said to be homozygous if it has identical genes on both chromosomes. It is referred to as heterozygous if the organism possesses two distinct alleles of the gene.
Therefore, if the alleles switched places but the order remains same then organism will be same too in case of homologus as well as heterologus chromosome.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes
Answers
Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.
This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.
NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.
Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.
What is Algae?Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.
Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.

Explanation:
The lac operon controls the transcription of a group of genes involved in metabolizing lactose in E. coli. A group of scientists tested how to activate the lac operon. In four different mediums, they varied whether glucose or lactose was present in the medium, as indicated by a or -.The scientist discovered that the lac operon is inducible, repressed by glucose and induced by allolactose. Which medium has the right conditions to metabolize lactose
Answers
Answer:
The correct answer would be - medium with lactose present and glucose absent.
Explanation:
There are genes present in lac operon that takes part in the lactose metabolism. These genes expressed only if a medium has lactose in absence of glucose.
In the absence of glucose and lactose is present, due to inducer the lac repressor is removed from the operator. This leads to the binding of CAMP to DNA as the CAMP levels are high. It helps in high transcription levels b binding RNA polymerase to promotor.
