Some researchers claim that sponge genomes have homeotic genes, but no Hox genes. If true, this finding would:______
a. strengthen sponges' evolutionary ties to the Eumetazoa.
b. mean that sponges must no longer be classified as animals.
c. confirm the identity of sponges as "basal animals."
d. mean that extinct sponges must have been the last common ancestor of animals and fungi.
e. require sponges to be reclassified as choanoflagellates.
Answer:
c. confirm the identity of sponges as "basal animals."
Explanation:
Homeotic genes (also known as homeobox genes) are genes that encode major transcription factors found in divergent species ranging from animals to plants. These genes contain an evolutionarily conserved sequence (homeobox sequence) that encodes a 60-amino acid DNA-binding domain (homeodomain) found in major transcription factors that interact with DNA and thus control body patterning during development of plants and animals. Moreover, Hox genes are a subset of homeotic genes only found in bilaterian animals that have arisen more recently in evolution. In animal embryo development, Hox genes control the body pattern along the head–tail axis.

alligator population, the population of
small fish and frogs will

Many types of fruits and vegetables can be fermented into alcoholic beverages. Such was the case recently when prisoners in Utah attempted to make an illegal beverage called “pruno”; however, someone added a weeks-old baked potato to the mix, letting a microbe into the party who was clearly uninvited. Consumers of the pruno began to develop difficulty swallowing, vomiting, double vision, and muscle weakness; three required ventilation therapy. No deaths were attributed to the contaminated beverage. A) What nervous system disease were the prisoners suffering from, and what was the specific organism involved? B) Based on your knowledge of this disease, what form of treatment was used to successfully avoid the worst outcomes of the disease in these patients?
Answer: beverages. Such was the case recently when prisoners in Utah attempted to make an illegal beverage called “pruno”; however, someone added a weeks-old baked potato to the mix, letting a microbe into the party who was clearly uninvited. Consumers of the pruno began to develop difficulty swallowing, vomiting, double vision, and muscle weakness; three required ventilation therapy. No deaths were attributed to the contaminated beverage.
Explanation:
Alcohol poisoning can be fatal and is caused due to harmful bacteria. The prisoners were suffering from a nervous system disease called Botulism, which affects the nerves and muscles.
What is Botulism?
Botulism is a nervous system disorder that affects the nerves and paralysis the muscles of the infected individual. It is caused by a bacteria called Clostridium botulinum that releases harmful toxins that interfere with the neurotransmitter.
The toxin affects the pathway of the acetylcholine neurotransmitter and causes muscle paralysis so that the muscles are not able to move. Toxin infection results in double vision and muscle weakness.
To avoid the outcome, the patients can be treated by giving the antitoxin that inhibits the action of the botulinum toxin in the body. Also, intentional vomiting can be induced to empty the stomach.
Therefore, the prisoners were suffering from a nervous system disease called Botulism.

How is thermal energy transferred during conduction? Check all that apply.
O Thermal energy is transferred between particles that are not touching each other.
O Thermal energy is transferred between particles that are in direct contact with each other.
O Thermal energy is transferred between objects of different temperatures.
O Thermal energy is transferred between objects of the same temperature.
O Thermal energy is transferred from slow-moving particles to fast-moving particles.
O Thermal energy is transferred from fast-moving particles to slow-moving particles.
Answer:
So you can rule out choice # 1. and I think you should check all the other boxes. See the description below. If the answer is incorrect then i'm sorry.
Explanation:
Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, similar to a game of pool where one moving ball strikes another, causing the second to move. Conduction takes place in solids, liquids, and gases, but works best in materials that have simple molecules that are located close to each other. For example, metal is a better conductor than wood or plastic.
6. A patient has been eating healthy foods, but his digestive system is not
doing what it usually does. Can this patient still exercise normally?
Answer:
This question is not complete as it lacks options. The options are:
A) Yes, as long as he can still breathe, his cells will have all the molecules they need to release energy.
B) No, his digestive system is not breaking down oxygen into molecules small enough to get inside his cells.
C) No, molecules from food are not combining together to be large enough for his cells to use.
D) No, molecules from food are not getting broken down small enough to get inside his cells.
The answer is D
Explanation:
Digestion is a very vital metabolic (catabolic) process in living organisms. It is very true that food is needed in order to obtain energy, however, that complex food molecule must be broken down into simpler ones via the process of DIGESTION in order for it to enter our cells and be used in the process that synthesizes energy (cellular respiration).
In this case, a patient is said to have been eating healthy foods but his digestive system is not functioning optimally (normally). This means that the patient's body cannot breakdown the healthy food into simpler molecules (glucose) thatt can enter into his cells for energy to be produced. Therefore, for this reason, the patient cannot exercise normally.
Potassium has a half-life of 12 hours. What fraction of a 100g sample is left after 48 hours
Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g

Explain how bacteria become resistant to antibiotics
Answer:
Some bacteria due to their structures and physiology are inherently resistant to some antibiotics. This could be due to lacking transport mechanism or lacking receptor sites. Bacterium develop resistance mechanisms by using instructions provided by their DNA. Resistance genes are often found in plasmids which are small pieces of DNA that carry genetic instructions from one germ to another. Meaning that some bacteria can share their DNA and cam make other germs become resistant.

Which process transfers heat from the sun to the ground?
the process of Radiation
Answer:
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection. The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun.
