The answer is D. they recycle nutrients into the soil
The correct answer is option D. They recycle nutrients into the soil.
The wetlands are the water the land water bodies, which are supplied with the water seasonally or throughout the year. All the type of the wetlands can support growth of the life forms, which can be seasonal or annual. Some o the wetlands are polluted by human activities, but not all of them. Swamps are a type of wetlands.
All the wetlands are involved in the recycling of the nutrients back into the soil. A wetland system have a rich diversity of flora and fauna, which can help in filtration of various sediments from water, recycling or removing nutrients and pollutants. In the wetlands, the water also come from the runoffs, the inorganic substances present in the water can be filtered and added to the sediments.
_____ is the main energy source for all life on earth. Chlorophyll Water Sunlight Nitrogen
Answer: Sunlight
Sunlight is the main source of energy for all life forms on earth. It is trapped by the green plants and other autotrophic organisms in order to conduct the process of photosynthesis. In photosynthesis, the light energy from sun is converted into chemical energy in the form of food. The plants are eaten by other organisms such as animals, birds and humans as a source of food and energy.
A small population of prairie dogs lives in a habitat that does not undergo any changes for a long period of time. How is genetic drift likely to affect this population?
Answer
a)It will accelerate the appearance of new traits in members of the population who are more “fit” for survival.
b)It will allow most members of the population to live longer because they will inherit many beneficial adaptations.
c)It will increase genetic diversity as new alleles are introduced to the gene pool from neighboring populations.
d)It will reduce genetic diversity by decreasing the frequency of some alleles a ...?
Answer:
The correct answer would be d) It will reduce genetic diversity by decreasing the frequency of some alleles.
Genetic drift is one of the methods of evolution in which frequency of certain genotype or alleles is reduced in a population.
It mainly occurs when population size reduces to a very small size due to a random event such as natural disaster, over-hunting et cetera.
The decrease in population size results in the loss of certain alleles or genotype from the population.

Plant cells perform photosynthesis,which occurs in the
A) chloroplast
B) cytoplasm
C) mitochondria
D) nucleus
Plant cells perform photosynthesis, which occurs in the chloroplast. Therefore, the correct option is option A.
The equilibrium of our planet's ecosystems is maintained in large part by photosynthesis. Plants act as the planet's "lungs" by absorbing carbon dioxide from the atmosphere and releasing oxygen through this amazing process. The generation of glucose, a form of sugar that serves as the primary energy source for plants, is also a result of photosynthesis. Chloroplasts, teeny organelles found inside plant cells and containing chlorophyll, are where the process of photosynthesis takes place. The solar energy from the sun is captured by this green pigment.
Therefore, the correct option is option A.

The olfactory system is the sensory system that deals with the sense of smell. please select the best answer from the choices provided t f
The right answer is true.
At the anatomical level, the olfactory system is composed of two structures, the main olfactory system whose stimulation induces sensations of smell and the trigeminal system that induces somatosensory sensations (tactile, thermal, pain, humidity). There is a third part called "vomeronasal organ", which is set back in the opening of the nostrils. In humans, the vomeronasal organ remains in a rudimentary state because its afferents nerve disappears from the 18th week of the embryonic life.
If a mutation occurs in a body cell and the mutation changes the phenotype of the individual, what will happen to the offspring of the individual?
A. The offspring may or may not inherit the new phenotype.
B. The offspring will inherit the change in genotype but not the phenotype change.
C. The offspring will inherit neither the genotype or phenotype change.
D. The offspring will inherit the new phenotype.
The correct answer is (c) The offspring will inherit neither the genotype nor the phenotype change.
Mutation is a slight change in the genetic material of cell.The mutation that is carried from one generation to other is to be in the germ cell. The mutation that occurs in the body cell is not inherited to another generation. The mutation that occurs in a body cell might change the phenotype of the person but is not transferred to another generation. The conclusion is that the offspring will not have any change in the phenotype and genotype of the body.

Which of the following is most likely to be observed by a physiologist?
Bone, called osseous tissue, is the most rigid connective tissue.
Epithelial tissue is made up of one or more layers of tightly packed cells.
The nervous system is composed predominantly of neural tissue.
The oily secretions from eye ducts prevent the lids from sticking together.
The correct observation that a physiologist is most likely to make is that The oily secretions from eye ducts prevent the lids from sticking together.
To understand why this statement is the most likely observation for a physiologist, let's consider the other options:
1. Bone, called osseous tissue, is the most rigid connective tissue. This is a true statement about the nature of bone tissue, but it is more of an anatomical or histological fact rather than a physiological observation. Physiologists study the functions of living organisms and their parts, so while they would understand this fact, it is not a dynamic physiological process they would observe.
2. Epithelial tissue is made up of one or more layers of tightly packed cells. This is another anatomical description. Epithelial tissues do have important physiological functions, such as protection, secretion, and absorption, but the statement itself describes structure rather than a specific physiological activity that a physiologist would observe.
3. The nervous system is composed predominantly of neural tissue. Similar to the first two options, this is a statement of composition and does not describe a physiological process or observation. Neural tissue does indeed carry out the critical functions of the nervous system, such as transmitting signals, but the statement itself is more about the makeup of the nervous system than an observable physiological event.
4. The oily secretions from eye ducts prevent the lids from sticking together. This statement describes a clear physiological function. The oily secretions, produced by the meibomian glands in the eyelids, are part of the tear film that keeps the eye moist and prevents the eyelids from sticking together when they close. This is a dynamic process that a physiologist could observe and study in the context of the normal functioning of the eye.
In conclusion, the fourth statement is the most likely observation a physiologist would make because it directly relates to the function of a physiological system, which is the primary focus of physiology.

Which nation was able to broker an armistice agreement between North and South Korea, ending the fighting?
Answer:
The Armistice Agreement to end the war between the two Korean nations was brokered by India.
Explanation:
The Korean Armistice Agreement was signed on July 27, 1953 by U. S. Army Lieutenant General William Harrison, Jr. representing the United Nations Command, the Chinese people's Volunteer Army (PVA) and North Korean General Nam II representing the Korean People's Army. This agreement brought about the complete cessation of the hostilities of the war.
India played a mediator in the war, bringing resolutions to ensure peace and ceasefire between the warring nations. The war had never formally ended and this armistice was the truce that will bring the nations into a standstill until further solutions could be found. This armistice suggested the establishing of a Neutral Nations Repatriation Commission (NNRC) chaired by Indian General K. S. Thimayya, which will decide the fate of over 20,000 prisoners of war (POWs) from both sides, among the many issues to be resolved. Though this armistice was not the final solution for the war to stop, it brought a piece of relief for the people and also for the governments until a permanent solution can be found.

Succession occurs because _______.
a.
organisms gradually change the environment
b.
climax communities are not possible
c.
dominant organisms drive out pioneer species
d.
ecosystems never reach a sustainable point
Correct answer: A) Organisms gradually change the environment
Succession occurs when a disturbance takes place in the environment, it can occur either by the disturbance of minor or major order disturbance.
The major disturbance can be caused due to the natural cause like the volcanic eruption and minor disturbance caused due to a natural or human cause like the forest fire.
Based on the type of disturbance succession is classified into two types of primary and secondary succession.
Primary succession is said to occur when a community or a group of the species evolve from a barren land. The land is fresh and new and no life is found on it.
Example: Succession after the volcanic eruption is said to be primary succession.
Secondary succession is said to occur when the disturbance destroys the whole ecosystem, but still, there is an availability of soil, nutrient, and seed in the ecosystem.
Example: Forest fire

which of the following could result from a algae bloom in a river.
a.algae purify water
b.local plants produce flowers early
c.fish would die
d.plant and animal population would increase
Algae use the presence of increased nutrients and enhance their own growth. Tthey produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This could lead to the death of aquatic animals, such as fish, that depend on oxygen.
