Answer:
a. mixotrophs
b. autotrophs
c. syntrophs
d. phototrophs
e. heterotrophs
f. chemolithotrophs
g. chemotrophs
Explanation:
Autotrophs are organisms that can synthesize their own food using carbon dioxide (CO2) and water (e.g., algae, cyanobacteria, plants, etc). Syntrophs are organisms that utilize products from other organisms (e.g., mites that consume human dead-skin). Phototrophs are organisms that synthesize their own food by using the energy provided by sunlight (e.g., green plants). Heterotrophs are organisms that cannot synthesize their own food, obtaining energy and nutrients by consuming other organisms (e.g., animals). Mixotrophs are flexible organisms that obtain their food by using a mix of different sources of energy and carbon. Protists that combine autotrophy and heterotrophy are considered mixotrophs. Chemotrophs are organisms that obtain energy by the oxidation of electron donors from the environment, by using both organic sources (chemoorganotrophs) and inorganic sources (chemolithotrophs). Examples of chemolithotrophs include sulfur/iron-oxidizing bacteria, while chemoorganotrophs include the most known bacteria and archaea.
What is the difference between Desserts, Grasslands and Forests?
Answer:
yaeh
Explanation:
Forests occupy the most favourable environments, where moisture is adequate for growth and survival of a tall, dense vegetation dominated by trees. Deserts are found where moisture is so lacking that a continuous, permanent vegetation cover cannot be maintained. Grasslands lie between these two extremes
Explanation:
Desserts: A desolate terrain, especially one with little water or vegetation; a wasteland.
Grassland: An area dominated by grass or grasslike vegetation.
Forest: A dense collection of trees covering a relatively large area. Larger than woods.

A heterozygous female with long whiskers mates with a heterozygous male with long
whiskers... W=long whiskers w=short whiskers
What is the PHENOTYPIC RATIO of the offsprings?
Answer:
3 long whiskers: 1 short whiskers
Explanation:
This question involves a single gene coding for whiskers length in a certain animal. The allele for long whiskers (W) is dominant over the allele for short whiskers (w). This means that a heterozygous individual (Ww) will possess a long whisker.
According to this question, a heterozygous female with long whiskers (Ww) mates with a heterozygous male with long whiskers (Ww). The proportion of offsprings that will be produced from this cross (see punnet square) is as follows:
WW, Ww, Ww, ww
WW, Ww, Ww offsprings will possess a long whisker while 'ww' offspring will possess a short whisker. Hence, the phenotypic ratio will be 3 long whiskers: 1 short whiskers

How do T cells coordinate the immune system?
Answer: Helper T cells, or Th cells, coordinate immune responses by communicating with other cells. In most cases, T cells only recognize an antigen if it is carried on the surface of a cell by one of the body's own MHC, or major histocompatibility complex, molecules.
Explanation:
Answer:
T cells identify pathogens based on antigens on the surface of pathogens. The T cells then multiply and stimulate B cells to produce antibodies. The antibodies attach to the antigens, making the pathogens a target for phagocytes.

Why is parthenogenesis considered an adaptation?
Yeasts are single-celled eukaryotic organisms. Yeasts undergo mitotic division when conditions are favorable. When limited nutrients are available, yeasts start dividing by the process of meiosis.
What is a likely reason for the change from mitosis to meiosis during reproduction under these conditions?
The process of meiosis produces greater numbers of yeast cells at a faster rate as compared to mitosis.
Crossing over of genes during meiosis increases diversity and the chance of survival of the next generation.
Duplication of genes during meiosis ensures efficient functioning of the newly formed yeast cells.
The yeast cells formed by meiosis are able to adapt as well as the parent cell because they are identical.
Yeasts change from mitotic to meiotic division when conditions are unfavorable because meiosis increases genetic diversity and improves their chances of survival in unfavorable conditions.
During meiosis, crossing over of genetic materials between non-homologous chromosomes creates genetic recombination and makes the resulting offspring to be genetically more diverse than their parents.
The increased genetic diversity will increase the chances of survival of the offspring in a constantly changing environment. In other words, the more genetically diverse a population is, the more their chances of surviving adverse environmental conditions.

i. Identify an environmental problem associated with large-scale intensive agriculture on soil.
Intensive agriculture is resulting in the loss of ecosystem and is contributing to global warming.
• An agricultural mechanization and intensification system, whose main objective is to increase the productivity from the accessible land via several means like heavy use of chemical fertilizers and pesticides is known as intensive agriculture.
• The intensive agriculture is generally aimed to feed large population of humans, however, the method has contributed as one of the biggest threat to global environment, as it is resulting in the loss of ecosystem and global warming.
• It is accountable for the 80 percent of the tropical deforestation and emergence of novel parasites and reemergence of the parasites, which were under control at one time.
• The intensive farming hampers the beneficial plants and insects, and depletes and degrades the soil it relies upon.
• It is resulting in soil erosion and is resulting in the genetic erosion of the livestock species and crops around the globe.
Thus, intensive farming in order to feed large populations is eradicating the world agriculture slowly and gradually.
