5: What does water have to do with our metabolism?
Answers
Answer:
Studies have shown that drinking 17 ounces (0.5 liters) of water increases resting metabolism by 10–30% for about an hour ( 22 , 23 ). This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it up to body temperature ( 21 , 24 ). Water can also help fill you up.

Researchers are investigating the use of gene therapy as a treatment option for human genetic disorders, such as cystic fibrosis. When gene therapy is successful, how does it treat the disorder?
A. by activating, or "turning on," one or more genes
B. by deactivating, or "turning off," one or more genes
C. by incorporating a human gene into the genomes of bacteria or other organisms
D. by replacing a faulty gene with a normal gene in the human genome
Answers
Answer:
A
Explanation:
By replacing a faulty gene with a normal gene in the human genome. Therefore, option (D) is correct.
Gene therapy works by inserting a functioning gene into a patient's cells. A viral vector or other delivery method transports the normal gene into target cells.
In cells, the normal gene integrates into the genome and produces the functional protein that was missing or faulty in genetic disorder patients. Gene therapy replaces the damaged gene with a normal gene to repair the genetic origin of the condition and restore normal cell or tissue function.

Annie wants to have children, but she and her husband have been unsuccessful so far.
Do her cells in her ovaries need to go through mitosis or meiosis? Choose one, and
explain why.
Answers
Answer:
meiosis
Explanation:
The germ cells that enter meiosis become oocytes, the source of future eggs. Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase. Within the ovary, these oocytes grow within follicle structures containing large numbers of support cells. (i don't know if the explanation is correct but i know that it is meiosis)

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answers
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

Answers
Answer:
d
Explanation:
d
The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
What are amino acid?Amino acid is defined as any of the elements present in both plants and animals that come together to produce a substance (protein), which is essential for a healthy body and for growth. The metabolism of amino acids plays a crucial role in many biological processes that take place inside the human body.
An examination of the first complete sequence of the gorilla genome suggests that humans and gorillas last coexisted 10 million years ago. The gorilla is the last of the surviving great apes, including humans, chimpanzees, orangutans, and gorillas, whose entire genetic sequence has been compiled.
Thus, the monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.

what is the advantage and disadvantage of the Ocotillo and Hummingbird relationship
Answers
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.
What are the various advantages and disadvantages of the relationship ?The advantages and disadvantages of this relationship can be described as follows:
Advantages:
Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.
Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.
Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.
Disadvantages:
The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.
Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.
If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.
Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.
