Ticks carry bacteria that cause Lyme disease. Ticks do not get Lyme disease, but they can transfer the bacteria to humans, who can get the disease. Which of the following statements best describes the relationships among the bacteria, the ticks, and the humans?a. The relationship between the bacteria and the ticks is competition, and the relationship between the ticks and the humans is predation.
b. The relationship between the bacteria and the ticks is competition, and the relationship between the ticks and the humans is parasitism.
c. The relationship between the bacteria and the ticks is commensalism, and the relationship between the ticks and the humans is parasitism.
d. The relationship between the bacteria and the ticks is commensalism, and the relationship between the ticks and the humans is predation.

Answers

Answer 1

Answer: The answer is c. The relationship between the bacteria and the ticks is commensalism, and the relationship between the ticks and the humans is parasitism.

Commensalism is a relationship between two organisms in which only one of them has benefit, and the other one is not affected. Bacteria are carried by ticks, so bacteria have a benefit from the relationship. Tick is not affected by bacteria, it does not get Lyme disease. Therefore, the relationship between ticks and bacteria is commensalism.

The relationship between ticks and humans is parasitism. Parasitism is non-mutual relationship between two organisms in which one of them (tick) benefits at the expense of the host organism (human).

Which of the following observations would lead a geneticist to suspect that an inherited disorder of cell metabolism is due to a defective mitochondrial gene?

Answers

Answer:

The genetic disease may be defined as the disease that can be pass down from the parents to their progeny. Different types of inherited disease are cystic fibrosis, sickle cell anemia and thalassemia.

The defect in the mitochondrial gene can also be transfer from one generation to the next generation. In this case the disease is transfer from the mother to their offspring as the mitochondria of the mother only can be transmitted to the offspring. The trait cannot be passed by the fathers.

What is the main function of the large intestine?A. digestion of proteins
B. absorption of nutrients
C. breaking down complex carbohydrates
D. removing water from undigested waste

Answers

The main function of the large intestine is to remove water from undigested waste. Therefore, the correct answer is option d.

The large intestine, also known as the colon, plays a crucial role in the final stages of the digestive process. Its primary functions include:

Absorption of Water: One of the key functions of the large intestine is to absorb water from the remaining undigested food materials (chyme) that enter it from the small intestine. As chyme moves through the large intestine, water is progressively absorbed, which results in the formation of more solid feces.
Formation of Feces: As water is absorbed, the contents of the chyme become more concentrated and solidified in the large intestine. This process transforms the liquid chyme into feces, which is then stored in the colon until it is ready to be eliminated from the body.
Storage and Concentration: The large intestine also serves as a storage organ for fecal matter, allowing the body to control the timing of bowel movements. It concentrates and compacts the waste material.
Microbial Fermentation: The large intestine is home to a diverse population of beneficial bacteria known as the gut microbiota. These bacteria assist in the final stages of digestion by fermenting certain indigestible carbohydrates and producing some vitamins and gases.

The large intestine does not play a significant role in the digestion of proteins, absorption of nutrients (the majority of nutrient absorption occurs in the small intestine), or the breakdown of complex carbohydrates (most carbohydrate digestion occurs in the small intestine as well). Its primary functions are related to water absorption, feces formation, and the maintenance of a healthy gut microbiota.

Therefore, the correct answer is option d.

The difference between protostomes and deuterostomes is _____. protostomes have only an ectoderm and endoderm protostomes have only a mesoderm protostomes develop a mouth first and then an anus protostomes develop an anus first and then a mouth

Answers

Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.

In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.

Final answer:

The main difference between protostomes and deuterostomes is the sequence in which the mouth and anus develop during embryonic development. Protostomes develop a mouth first, and deuterostomes form an anus first.

Explanation:

The primary difference between protostomes and deuterostomes lies in the sequence of their embryonic development.

Protostomes, which include organisms like insects and mollusks, follow a developmental sequence where the first opening in the embryo becomes the mouth, and the second becomes the anus.

On the other hand, deuterostomes, including organisms like vertebrates and echinoderms, have a developmental sequence where the first opening becomes the anus, and the second becomes the mouth.
