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.

A baby with blood group AB I born into a family where the mother has blood group type B and the father has type O
Determine whether the husband is the biological father of the baby
The baby AB received the IB allele from the mother and the IA allele from another person. The husband is not the biological father of the baby.
What are the blood type alleles?
Blood type is coded by a triallelic gene
IA allele is dominant over the i alleleIB is dominant over the i allele IA and IB are codominanti is the recessive alleleThe genotypes and phenotypes are
IAIA and IAi → Type AIBIB and IBi → Type BIAIB → Type ABii → Type 0
In the exposed example,
Baby → AB → IAIBMother → B → IBIB or IBiHusband → 0 → ii
The baby carries one IA allele and one IB allele.
The IB allele was inherited from the mother. The husband could only transmit a recessive allele i. But the baby does not carry any recessive allele.
The baby received the IB allele from the mother and the IA allele from another person.
The husband is not the biological father of the baby.

a.growth and repair; growth, repair, and reproduction
b.reproduction; growth and repair
c.reproduction; growth, repair, and reproduction
d.growth, repair, and reproduction; growth, repair, and reproduction
In the case of asexual, single-celled creatures, cell division is needed for reproduction, while simple cell division is employed for growth and repair in multicellular organisms (option B).
Cell division in unicellular & multicellular organisms-
The mechanism through which a mother cell splits into two or more daughter cells is known as cell division.Cell division aids in the growth, maturation, healing, and production of reproductive cells in multicellular organisms (sperms and eggs). A poorly controlled process called uncontrolled cell division can lead to illnesses, most notably cancer.Binary fission is a method of prokaryote reproduction used by bacteria. Cell division is the sole process that unicellular organisms can use to create new individuals. The result of cell reproduction in both prokaryotic and eukaryotic cells is a couple of new cells which are genetically identical to their parent cell. Daughter cells are distinct entities in unicellular organisms.Therefore the correct answer is an option (B).

Which theory is most widely accepted in describing the formation of our universe?
the Big Bang Theory
the Singularity Theory
the Steady State Universe
che Eternal Inflation Theory
Answer:
The Big Bang Theory.
Explanation:
The Big Bang Theory is the most widely accepted hypothesis for the origin of the universe as we know it. It's implications are somewhat vague, as there is no concrete way to determine what really happened to create our universe, but it still holds water.
The basics of the Big Bang Theory is that a singularity was formed, a very small ball with infinite density and unimaginable heat. This singularity's expansion is what created the universe, essentially, a big bang.

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 :

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.

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.
