Answer:
One factor limits a population at a time. Suppose the area that had only enough food for 500 armadillos suddenly had enough food for 2,000 armadillos, but only enough water for 1,000 armadillos. The population still couldn't grow to 2,000 armadillos. Water would keep the population at 1,000 armadillos. In this case, water is the limiting factor.
Explanation:
The size of a population is limited by the carrying capacity of the environment. The carrying capacity is the maximum number of individuals that an environment can support. The carrying capacity of an environment can be limited by the availability of food, water, shelter, and other resources. Biodiversity is the variety of life in an area. The carrying capacity of an environment can also be limited by the number of different species that can coexist in an area.

a. What is the main problem that your central nervous system will try to solve?
b. What is the somatic nervous system likely to be doing?
c. Which part of the autonomic nervous system is likely to be active, and what will it be doing?
The main problem that your central nervous system will try to solve is how to get out of this place.
B. What is the somatic nervous system probably doing?It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.
ç. Which part of the autonomic nervous system is likely to be active and what is it doing?The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.
What are the physiological responses of adrenaline binding in the sympathetic autonomic system?Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.
With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.

The sperm will be immature and sperm count will be lower if the bulbourethral gland in males fails to perform its function
The bulbourethral gland or Cowper's gland, which is homologous to the Bartholin's gland in females, produces pre-ejaculate that cleanses and lubricates the urethra prior to the arrival of the semen.
The Cowper's glands or bulbourethral glands produce the first fluid that leaves the urethra in order to neutralize the acid left from the urine. The sperm like a basic or alkaline environment in order to survive.

The stems and leaves of many grasses, and sometimes the entire grass plant, die each year during the dry or cold season. The dry husks of the grasses easily burn so that grass fires during the dry season are common. The result is that many trees cannot grow in these grasslands because they are stunted by fire. If trees could grow readily in these areas, they would rob grasses of sunlight and water. What does this phenomenon tell us about natural selection and adaptations that help organisms send their genes to the next generation?
The organisms would never sacrifice themselves so that other organisms carrying their genes can survive. Thus, option "B" is correct.
What is Natural selection?Natural selection is the process in which the species are adapted to their environment.
Natural selection leads to evolution when the people having certain characteristics possess the greater chance of survival than the others that are not adapted to the changes, these adapted characteristics are passed to the next generations.

discuss the role that microbiologists can and have played in helping to reduce the number of infections caused by parasitic helminths
Invertebrates with long, flat, or rounded bodies are known as helminths. These are the parasitic worms which cause a no. of diseases, including some that affect the musculoskeletal system.
An example of two most common helminths which are known to be pathogenic to humans are:
1) Ascaris , the common round worm which causes ascariasis. Its symptoms are internal bleeding, muscular discomfort, fever, etc.
2) Wuchereria (W. bancrofti and W. malayi), the filarial worm that causes filariasis (elephantiasis) . Lymphatic vessels of the lower limbs & genital organs are frequently affected.
The roles that microbiologists play in helping to reduce the number of infections caused by parasitic helminths are :
1) They detect parasites at an early stage of infection, resulting in less harm to the host.
2) The diagnosis provides useful information for identifying and recovering from human parasites.
3) Microbiologists thoroughly research these parasites in an effort to understand how these helminths function, develop, and interact with their surroundings.
4) They collect the sample (feces in case of these diseases) and test them for the parasites that are or maybe the illness's cause.
5) They also provide information on the anthelmintic medications' in vitro activity against the discovered parasite.
6) They also study the life cycle of the parasites which determines their impact on food web structure.
7) Their study indicates whether the disease is infectious or non-infectious so that the precautions can be taken accordingly.

In 1926, Kurosawa and colleagues extracted a compound from a fungus that caused abnormal growth in rice seedlings that eventually led to the death of the plants. Gibberellin was the plant hormone found in the extract and was responsible for the disease symptoms.
A group of plant hormones known as gibberellin promotes germination, flowering, and stem elongation.When rice farming in Japan was being harmed by the Bakanae (foolish seedling) illness in antiquity, Gibberellins were first discovered. It led to the rice seedlings being longer and developing pale yellow leaves, which reduced the yield.Kurosawa, a Japanese scientist, was attempting to determine why and how Gibberella fujikuroi, a fungus, was producing these alterations in plants. He was successful in filtering the fungal extract that was discovered to be in charge of the disease's onset. Then, in 1935, Yabuta separated the active ingredient and gave it the names gibberellins A and B.

Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.
The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection.
