How can scientist explain our ability to feel empathy? Can evolution explain the types of group’s primates will organize themselves in? What is different about Homo sapiens from other non-human primates? Does this explanation make sense to you? Why or why not?
Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.
Can evolution explain the types of primates in the group into which they will organize themselves?As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.
How is Homo sapiens different from other non-human primates?Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"
With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.

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 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.

A mixture cannot be described by a chemical symbol or formula.
What is a mixture?A mixture is a substance that consists of 2 or more chemically different substances.
Examples of mixtures are sand and salt, water and kerosine, oil and water, etc.
Each substance in a mixture maintains its chemical identity. In other words, components of mixtures do not react with each other.
Thus, the components of mixtures can be recovered using relevant separation techniques.
Mixtures can be homogenous when the different components are uniformly distributed. They can also be heterogenous when the components are skewed to a specific side of the mixture.
Due to the fact that the chemical identity of the components of mixtures remains, it becomes impossible to assign a chemical symbol or formula to mixtures.
Therefore, mixtures can only be named according to the different components but cannot be assigned chemical symbols or formulas.

Cystic fibrosis is a recessively inherited disorder that results from a mutation in the gene encoding CFTR chloride ion channels located on the surface of many epithelial cells. As shown in the figure, the mutation prevents the normal movement of chloride ions from the cytosol of the cell to the extracellular fluid. As a consequence of the mutation, the mucus layer that is normally present on the surface of the cells becomes exceptionally dehydrated and viscous.
An answer to which of the following questions would provide the most information about the association between the CFTR mutation and the viscous mucus?
O Is the mucus also secreted from the cells through the CFTR proteins?

Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
Based on your knowledge of flowers, why do you think most flowers are bright in color?
The parts of a plant that are responsible for reproduction are the flowers, they are present only in the most evolved group of plants called angiosperms. Flowers can be hermaphroditic or monoecious when they have both female (carpels) and male (stamens) structures.
Describe what happens during the seed development process.Germination is a succession of stages that resume the development of the embryo and the beginning of the formation of a new seedling. We can summarize germination as the process of transforming the seed into a new plant. The seed consists of the embryo, endosperm and integument.
Based on your knowledge of flowers, why do you think most flowers are brightly colored?Are mainly related to pollination by animals. This is due to the fact that the flower acts as a form of attraction for pollinators, therefore, mechanisms are needed to guarantee the visitation of these animals.
With this information, we can conclude that flowers inherit their appearance through genes. Pigments are born in these plants, producing a range of colors across the spectrum. The same chemical, carotenoid, that produces the pigment in tomatoes and carrots also produces the yellow, red, orange colors in certain flowers.
