Answer:
Ecological and ethological approaches to the study of behaviour. The natural history approach of Darwin and his predecessors gradually evolved into the twin sciences of animal ecology, the study of the interactions between an animal and its environment, and ethology, the biological study of animal behaviour.
clasificatoin of hormones
Answer and Explanation:
Hormones are substances that administer the human body having several different and essential functions for the proper functioning of the body. There are several different types of hormones and they are classified into four groups called peptides, steroids, amines and eicosanoids.
Peptides are hormones that have 3-20 amino acids. Among these hormones we can mention insulin, glucagon and somatostatin.
Steroids are hormones produced from cholesterol. Among them we can mention Cortisol, Aldosterone and Testosterone.
Amine hormones are those that are released into the thyroid and adrenal glands. These hormones circulate freely in the blood. Among them are epinephrine and norepinephrine.
Eicosanoids are the hormones derived from arachidonate. Among them are the hormones called prostaglandins, thromboxanes and leukotrienes.
On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB_ Elmo red
__bb Janice blonde
If two doubly-heterozygous Cookie-monster blue-haired muppets mate, and produce 3200 children, which of the follow values most closely represents the expected number of Elmo red-haired offspring? The answer allows for random variation in hair color.

Explanation:
Storz (2007) describes an adaptive response to low partial pressure of oxygen in an environment at high elevation. Describe three other environmental conditions besides high elevation that might result in adaptation to hypoxia. List an organism found in each of the described environmental conditions that would be predicted to exhibit adaptive responses to low partial pressure of oxygen.
Answer:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas.
Explanation:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas are the three other environmental conditions besides high elevation that might result in adaptation to hypoxia. These abilities will increase the resistance to lower oxygen levels in the surrounding environment. Fish is the organism which used these types of adaptation for their survival in the surrounding of low oxygen levels.

The following case study is a paraphrase from "Good Clinical Practice. Standard Operating Procedures for Clinical Researchers" (Kolman, J., Meng, P. and Scott, G. editors; John Wiley and Sons publishers, 1998):
“While a study subject and a relative were walking in town one day during the summer, a hanging flower basket fell on a study subjects head, resulting in the study subject falling down and becoming unconscious. The subject’s relative called for an ambulance. On arrival at a local hospital’s Emergency Department, in which the subject regained consciousness but could not recall the event, a x-ray revealed a fractured skull. The subject’s consciousness level at this point was deteriorating and after further tests a subdural hematoma was diagnosed, which was evacuated under general anesthesia. Postoperative recovery was uneventful and progressing well until day four, when the patient developed acute dyspnea (shortness of breath) at rest during visiting time. An emergency lung scan was performed that confirmed a diagnosis of pulmonary embolism. The study subject was anticoagulated and was eventually discharged from the hospital”
1. What is/are the AE/s in the case study?
2. Are there any AEs that are "serious"? If "yes", list them and state why they are serious.
3. What are your thoughts about the AE(s) being related to the study drug (NOTE: we do not know whether the subject is on active drug or placebo)?
A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
D)
The organism was able to transport water through specialized veins.
Answer:
The organism requires sunlight.

Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

Answer:
it may affect the animals and other tree's.
Explanation:
it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.
trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.

Describe the characteristics and classification of seedless vascular and nonvascular plants
Answer:
Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant.
1. These lignified tissues are also called vascular tissue and consist of water-conducting xylem tissue and food-conducting phloem tissue.
2. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances.
3. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.
4. The root is a true root that enables the plant to anchor onto the soil and gets nutrients from it.
5. The leaves are broad and have stomata that work for gas exchange and support transpiration.
6. The stem of vascular plants is multilayered with vascular tissue that helps in the protection and conduction of food and water.
7. The arrangement of these issues might be different in a different group of plants as it depends on the pattern of division of cells.
8. The xylem is composed of non-living matter, tracheids, and vesicles, hardened by lignin that provides a stiff structure to the tissue. 9. The phloem, on the other hand, contains living sieve elements that are not lignified.
10. Vascular plants are capable of surviving on land due to their ability to transport food, water, and mineral to different parts of the plant by creating pressure through the tissues.
11. Besides, they also have several modifications that facilitate their survival on land.
12. Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores.
13. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substances to all parts of the body via vascular tissue.
14. It is believed that vascular plants are a more evolved version of non-vascular plants and thus came later in the evolutionary history.
15. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams.
16. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. These plants belong to the group Pteridophyta.
17. The higher vascular plants are numerous and extremely diverse and are further divided into different subgroups.
18.Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses, etc.
Answer:
Definition of nonvascular plant
: a simple, low-growing, nonflowering plant (such as a moss or liverwort) that lacks specialized conducting channels for transporting water and nutrients
vascular plants have lignified tissues for conducting water and minerals throughout the plant.
