Codominance is an inheritance pattern. Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.
What is codominance?Codominance refers to the inheritance pattern in which a phenotype expresses two alternative variants coded by two alleles inherited from each homozygous parent.
When two individuals, that are homozygous and different for a trait, are crossed they produce heterozygous individuals.
These progenies express both parental phenotypes, as it is an additive expression of their parents' genes. Both alleles are equally expressed.
The is not complete dominance in these cases.
In the case of blood, the I gene determines the blood type of a person.
→ I is completely dominant over the i recessive allele.
→ Allele I can be either IA and IB, which are codominant.
The person IAi expresses the A blood type ⇒ complete dominanceThe person IBi expresses the B blood type ⇒ complete dominanceThe person IAIB expresses the AB blood type ⇒ codominance ⇒ both alleles are simultaneously expressedHuman blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.

Listening and hearing are essentially the same as both involve receiving aural and visual stimuli. True or false?.
It is a false statement that listening and hearing are essentially the same as both involve receiving aural and visual stimuli.
What is a stimuli?The term stimuli is used to describe any information that is received from the external environment. This information that has been received from the external environment must be interpreted by the nervous system of the individual. The interaction of an organism with it's environment tends to occur by the instrumentality of the sense organs present in the organism.
The term aural stimulus has to do with a sensation that is received by the ears while the term visual stimulus deals with the kind of sensation that is received with the ears.
Hence, it is a false statement that listening and hearing are essentially the same as both involve receiving aural and visual stimuli.

From a trough to a peak, the economy goes through
The economy will then start to shrink as it descends from the peak and enters recession.
What is happening to the economy during the trough phase?The economy's growth rate declined during the depression phase. Up until the demand and supply for products and services, as well as the prices of the factors, reach their lowest point, there is still a further decrease. Eventually, the economy sinks to its lowest point. The economy enters the peak phase when it reaches its highest level of output, which marks the end of growth. After this, a contractionary phase occurs as employment levels and housing starts start to drop.
The time between an economic activity's peak and its subsequent trough, or lowest point, is known as a recession. The economic cycle between its trough and peak is one of expansion.

Answer:
1. Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
2. In 1965, Mariner 4 and 9 probes found geological formations (Olympus Mans). The Mariner 4 sent back the first image of Mars. The Mariner 9 found erosion marks that indicated that there was once water on Mars. In 1976, the Viking 1 and 2 probes transmitted panoramic views of the soils. From 1965 to 1976, they were able to discover more about Mars over improving the technology. When the Viking probes were launched, we discovered more than when the Mariner probes were launched. For example, we were able to uncover how red and rocky the soils were.
3. We now receive information differently thanks to wireless technology. For instance, we now have computers and phones that let us contact someone by simply pressing a button. GPS may now be used to display various places. Additionally, we can now forecast the weather. We can know the weather for every day because forecasters have access to a ton of technology. Thus, we now substitute archaic methods for digital ones.
4. Fire alarm and air conditioning systems include technologies that incorporate various communication systems that enable them to react to changes in the atmosphere or temperature. Therefore, when the atmosphere's temperature fluctuates, they are utilized.
5. Viking 1 and 2 were used to find life on Mars. Since they launched the Mainer probes, they found that there was once water on Mars which later created the Viking 1 and 2 probes for further investigation. Along with finding life on Mars, they were also created to take better photos of the planet.
Why oxygen to form oxyhemoglobin but not haemoglobin oxide
Oxygen will form oxyhemoglobin and not hemoglobin oxide because it is referred to as a`protein which binds to oxygen atoms in the blood.
What is Hemoglobin?This refers to a protein in the body which carries oxygen molecules to various parts of the body. This is as a result of the compound which is referred to as heme which is responsible for the high affinity for oxygen. It ensures oxygen is distributed to other parts of the body.
On the other hand, formation of oxides means that a chemical reaction occurred with oxygen. There is however no chemical reaction formed as a result of this affinity which is why there is no formation of hemoglobin oxide in this specific type of scenario in the body system.
This therefore is the reason why oxygen forms oxyhemoglobin but not hemoglobin oxide and makes it the most appropriate choice.

The selective pressures operating in the late miocene, pliocene, and pleistocene that favored the adaptive radiation of monkeys and contributed to decreased diversity among apes are :-
The primates migrated from Africa to Europe and Asia.The sudden changes in the environment and the ecology was the reason behind the migration to the different parts.The sudden cooling in the northern latitudes led to the extinction of apes.The changes in the sea levels that made a path to travel through made the migration possible.How did the changes cause the diversity among apes? The plate tectonic movement caused the formation of the mountain ranges and the shifting of the oceans, this caused a drastic change in the environment and the ecology.The rainforests changed into woodlands and grasslands and at some other parts the decrease in rainfall caused the decrease in forest area and less food availability in that area.The change in environment caused the decrease in forest area in Africa and that caused the extinction of the apes and the new era apes that have adapted the environment then survived and moved to different parts of the world for survival.Know more about the miocene :
