The bryophytes, which include liverworts, hornworts and mosses, reproduce both sexually and vegetatively. The gametophyte is the most commonly known phase of the plant. All are small plants found growing in moist locations and like ferns, have motile sperm with flagella and need water to facilitate sexual reproduction.
Answer:
The microorganisms present metabolic wastes that serve as the primary source of food for other living things.
Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.
This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.
Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.
Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.
The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.
Explanation:
By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.
Answer:
c. our inhibitions and insecurities
Explanation:
The factors that influence what stimuli we notice and try to make sense of are
1. When some certain characteristics of external phenomena attracts our attention. There is an higher chance of noticing it --- things that STAND OUT.✔
2. An individual perception is controlled and regulated by the acuity of his/her senses.
Take for example, a person with a better sense of smell, its more attracted to the aroma of a freshly baked chocolate cake than others -----acuity of our senses.✔
3. Change or variation attracts attention, as this explains why one might ignore a friend's chat but will swiftly notice when his/her friend is tensed. --- Change or variation✔
4. What an individual choose to notice is also regulated by their personality and inner thoughts as morives play a important role in what we see and miss out on.
5. An individual perceive what he wants to perceive ----- the self-fulfilling prophecy (deals with individuality and perception of one's self)
Kindly note that the option c -our inhibitions and insecurities- does not influence what stimuli we notice and try to make sense of.
Answer:
a. add more of the enzyme
Explanation:
Enzymes have specific sites to which their substrates bind during the reaction. These sites are called active sites. When all the active sites of all the enzyme molecules present in a solution are bound to the substrate molecules, the enzyme is said to be saturated with the substrate. Under these conditions, more enzyme molecules are to be added to the solution to increase the reaction rate and to obtain the product at a fast rate. The addition of more enzymes will allow more substrate molecules to occupy the active sites and to be converted into the product/s.
Aerial roots allow the orchid to attach itself to trees.
