3) identify and describe three abiotic characteristics of ecosystems. Give an example of how each
characteristic could be affected by a human activity
Answers
Answer:
The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.
Explanation:
In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.
Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.
--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.
--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.
--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.

Dr. Pringle studies niche partitioning and competition reduction among coexistent species in Africa.
He is interested in knowing the exact source of food of different herbivorous species. To do so, he is using the technique of DNA metabarcoding.
He collects fresh animals' dung and gets the indigested plant cells.
DNA is isolated, sequenced, and compared with the DNI of known species, which are a potential source of food for these animals.
Once he matches the cells' DNA with the corresponding plant species from the database, he can use this information to detail the animal's source of food.
The importance of getting fresh, undigested cells from the dung, is that
The animal's digestive enzymes have not broken the cell walls and digested the cell content. The dung environmental conditions such as pH, temperature, or microbiota have not affected the cell's DNA.

Answers
Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
Answers
Answer:
C. Sperm would not be able to develop properly.
Explanation:
There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.
If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.
What is the function of "sc-rotum"?A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.
Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.
Thus, the correct answer is option C.

C. does not produce cells with the same genetic information than parent cell.
D. always produce somatic cells with the same characteristics, it does not matter the organ in the body.
Answers
Answer:
B. allows processes as growing and repair tissues in the body.
Explanation:
Mitosis is a process where a single cell divides into two identical daughter cells. During mitosis one cell divides once to form two identical cells and the dividing cell's chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.
The major purpose of mitosis is for growth and to replace worn out cells. It also plays an important part in the development of embryos.
Mitosis is divided into five stages:
1. Interphase- during interphase, the DNA in the cell is copied resulting in two identical sets of chromosomes. Microtubules also extend from the centrosomes outside the nucleus
2. Prophase- during this phase, the sister chromatids in each chromosome pair up, the nuclear membrane dissolves and the mitotic spindle consisting of microtubules and other proteins extend across the cell between the centrioles which move to opposite ends of the cell.
3. Metaphase- the chromosomes line up at the centre of the cell and the mitotix spindle attaches to eachmof the sister c hromatids.
4. Anaphase- the sister chtomatids are pulled apart to each end of the cell by the mitotic spindle.
5. Telophase- at each pole, a full set of chromosomes gather together, a membrane encloses each chromosome, the cell pinches at the middle and then divides into two. This is known as cytokinesis.
