We can use the word RINGER to memorize the characteristic of living things.
Respiration - the ability to breathe and respire.
Irritability - the ability to detect and react to stimulus
Nutrition - taking in nutrients (eg. Food) for energy to growth, repair etc
Growth - the permanent increase in size and mass
Excretion - to get rid of toxic, waste or excess materials
Reproduction - to make more of that organism.
In addition, there is also movement, which is an action which causes a change in place or position.
Only the organisms with these characteristics are categorized as living things.
Answer:
Meiosis
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.
The possible father's blood groups are B, AB.
<u>Explanation:</u>
If the mother blood type of A, and the father blood type is AB, B then the child is B. Each biological parent donates one of their two ABO alleles to the child. The blood types in our body are classified as the four paternal blood types and the four maternal blood types.
The blood type has the 16 combinations of the blood samples. The genetic information from the body is independently inherited to the ABO blood types alleles. In the Rh factor, the genetic information is inherited from the one parent to another.
Answer:
Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers, not to mention filamentous fungi and yeasts.
Explanation:
Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers are the organisms which can survive in highly acidic solution that have large amounts of iron, sulfur dioxide, carbondioxide, and oxygen molecule. In these organisms algae is autotrophic whereas archaea, bacteria, fungi, yeasts and protozoa are heterotrophic.
