2. What can you infer from the fact that ants make up
20 percent of the mass of all land animals combined?
a. Ants are very heavy
b. Ants live for a long time
c. Ants thrive in locations all over the world
d. Ants breed faster than any other organism on earth

Answers

Answer 1
D, because they are not heavy, so if they form 20 percent of the mass of all land animals combined it means that there are many ants in the world due to the fast breed
Answer 2

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.  

What are the major features of ants ?

Ants belongs to Formicide family  which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.

The diversity of ants is every where except Antarctica.

The body has three parts such as  a head, a meso-some and metasoma or gaster.

Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.

The reproduction in which young, queens  fly during mating time, fertilize with male, this flight is called as nuptial flight.

Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.

Thus, option D is correct.

Measures of events that occur in the brain and other parts of the nervous system are called neuronal measures.

Information is transmitted via neurons. They communicate between various brain regions and between the brain and the rest of the nervous system through electrical impulses and chemical signals. The intricate circuits of the nervous system are built from originally erroneous neuronal connections, and neural activity is essential for this process. Many common neurodevelopmental diseases, ranging from subtle learning deficits to severe developmental delay, may be caused by disruptions in the development of these specific circuits.The second most well-known method for capturing cerebral activity is electroencephalography, or EEG.

To line the airways and make mucus, which lubricates and protects the lung

There are numerous different cell types in the lungs. Epithelial cells make up the majority of lung cells. Mucus is produced by epithelial cells that line the airways and coat and shield the lung. Additionally, the lung cells contain blood, nerve, hormone-producing, and structural or supporting cells.

Air enters your lungs when you inhale (breath), and the oxygen in that air travels to your blood. A waste gas called carbon dioxide travels from your blood to your lungs at the same time and is exhaled (breathed out). Gas exchange is a procedure that is vital to life.

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of:______
a. protein.
b. glucose.
c. thiamin.
d. riboflavin.

Answers

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..

The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.

A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.

Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.

This is the primary distinction between the two types of cells.Bacteria have a single circular chromosome made of double stranded DNA, whereas humans have 46 chromosomes made of linear DNA. Similar to the genetic material present in all living things, this circular DNA serves to sustain bacterial growth, cellular respiration, and reproduction.Bacteria are typically thought of as genetically haploid, have a quick generation rate, and are quickly able to reach high population densities.

The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, caw, rabbit, bird, eagle, mountainlion, and fungi.

Note: Since you did not detailed the organisms you identified in part B, I will define what a trophic web is, and propose an example for you to understand.  

What is a trophic web?

The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

• The first link corresponds to a producer organism -autotroph-.

• The following links are the consumers -heterotrophs-: herbivores and carnivores.

• The last links are the decomposers that degrade organic matter from dead organisms.

Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Example.

To make the trophic web, first, you need to define the position of each of the organisms on the web.

Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.

Consumersheterotroph

Herbivores → These are the animals that feed on any part of the plants → Let us say we have a caw, a rabbit, and a bird.

Carnivores → These are the animals that feed on herbivores → Let us say a mountain lion and an eagle.

Decomposer → detritivorous organisms that take energy from dead matter → Fungi

So, our organisms are

plants, caw, rabbit, bird, mountain lion, and eagleFungi

Plants directly provide energy to the caw, the rabbit, and the bird.

Plant >> Caw, Rabbit, Bird

The eagle takes energy from the rabbit and the bird.

Rabbit and Bird >> Eagle

The mountain lion takes energy from the caw, the rabbit, the bird, and the eagle.

Caw, Rabbit, Bird, Eagle >> Mountain lion

Fungi takes energy from dead organic matter

Plants, Caw, Rabbit, Bird, Eagle, Mountain lion >> Fungi

Answers

Certain foraminifera (shellless protozoa) have inconsistent fossil records. The mode of evolution they represent is punctuated equilibrium.

C. punctuated equilibrium

What punctuated balance?

Punctuated equilibrium is an evolutionary theory proposed by North American paleontologists Niles Eldredge and Stephen Jay Gould in 1972, which proposes that most populations of sexually reproducing organisms experience little change over geologic time, and when evolutionary changes in phenotype occur , they occur in a rare and localized way in rapid speciation events called cladogenesis.

With this information, we can conclude that in gradualism mutations occur slowly and gradually so that the appearance of new species occurs in a subtle way. In turn, in punctuated equilibrium, mutation rates are faster and when a new species appears, this event occurs in small jumps.
