Answer:
Heterozygous dominant
Explanation:
This means that the genotype has both alleles of the gene hence referred to as heterozygous. The dominant of the two alleles is the one that is expressed in the phenotype of the individual expressing the genotype. The effects of the recessive allele are masked by the dominant allele.
Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
Answer: warm water
El Nino is a climate change pattern which describes the unusual warming of water of Pacific Ocean. The atmospheric pressure above the water decreases. The warm water increases the temperature of wind. The warm wind moves towards the East Equator.
Answer:
In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.
Explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.
- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- <em><u>Bacteria</u></em><em> is a prokaryotic organism.
</em>
- <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles.
</em>
- <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
