The earliest known life forms fossilized microrganismos found in hydrothermal vent precipitates, that many have lived as early as 4.28gya relatively soon after oceans formed 4.41 gta, and not long after the formation of the earth.
starting in the 1980s many scientists argued that life got its start in scalding, mineral-rich waters streaming out of the deep sea hydrothermal vents evidence for hot start included studies on the tree of life which suggests that most primitive species of microorbs alive today thrive on hot water
earth was formed around 4.54 gya approximately 1/3 of the age of the universe, by accretion form the solar nebula, volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained no oxygen

what does divine creation mean? did charles darwin agree with this idea?
Answer:
The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and On the Origin of Species reflects theological views. Though he thought of religion as a tribal survival strategy, Darwin still believed that God was the ultimate lawgiver, and later recollected that at the time he was convinced of the existence of God as a First Cause and deserved to be called a theist.

how your innate immunity protects you from the pathogens you encounter.
Answer:
General defenses are the first line of defense and are collectively called: the Innate Immune System. This system is called "innate" because it is genetically encoded, the traits that protect us from infections can efficiently be transmitted to our offspring.The innate immune system recognizes molecular structures that are produced by pathogenic microorganisms. Microbial substances that stimulate innate immunity are often shared by different classes of microbes and are called molecular patterns associated with pathogenic microorganisms
Explanation:
The first defenses that external agents face when trying to penetrate the body are totally nonspecific and are made up of the anatomical, physical, chemical or biological barriers characteristic of each location, while some, such as temperature, are systemic. Between all they make up innate immunity. The importance of these barriers is reflected in the ease with which infections are acquired when one of them fails. Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.). Innate immunity constitutes a less evolved and specific defense than the adaptive one, since the same mechanism (cells, soluble factors, etc.) acts against different agents. Furthermore, repeated exposures to a foreign molecule or agent elicit a similar response and with the same intensity in all of them; that is, it lacks immune memory. The fact that it is a less evolved and specific response is compensated by its speed, since it occurs in hours, and because its intensity is not linked to a previous contact with the foreign agent. Furthermore, its action is essential for the subsequent development of the adaptive immune defense, to which the agent must be exposed once these barriers have been overcome.

1. Write a statement that uses (correctly) the terms gamete, fertilization, and zygote. (2)
Answer:
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.

How do we know our current money has value? (5 points)
People talk about money a lot.
It is backed by gold.
People accept it in exchange for goods or services.
It has many security measures.
Answer:
The correct answer is - people accept it in exchange for goods and services.
Explanation:
Money is valuable because we know that it is "accepted." Money can be used to purchase goods and services even though it is no longer backed by gold. Security measures prevent counterfeiting but do not add value.
People know at that time that their current money has value when they accept it in exchange for goods or services, which is option C, as money is a medium of exchange.
The value of money is influenced by central banks. Different countries have different currencies, but the currency that is stable and has more security has more use. Money is also linked to the underlying economics, such as the ability of a country to buy and manufacture goods, thus increasing the economy. There are also many security measures, such as unique designs, special inks, holograms, etc., that are helpful for maintaining trust and confidence in the currency.

What happens to DNA in the interphase stage of cell division?
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.

Answer:
Both mitosis and meiosis occurs in Amoeba.
Explanation:
Both mitosis and meiosis occurs in Amoeba. Those kinds of Amoeba that reproduces through asexual reproduction uses mitosis in which a single parent Amoeba cell is divided into two identical daughter Amoeba cells while on the other hand, Myxamoeba reproduce through sexual reproduction in which meiosis cell division is used. In this type of reproduction, the daughter Amoeba is different from their parents Amoeba.
how your innate immunity protects you from the pathogens you encounter.
Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

please help fast. How do both systematics and taxonomy relate to phylogeny?
Answer: “ Systematics is concerned both with Taxonomy, the naming and classification of life, and Phylogeny, the science and study of understanding the family tree of all life on Earth. ... Systematics, then is the classification of life according to its phylogenetic (evolutionary) relationships.” -http://palaeos.com/systematics/
Systematic is related to the study of the evolution of a species over time and the relationship between them. Taxonomy is the naming and classification of animals and plants. The phylogeny is the study of family trees of every species on Earth, Hence they all are related to each other.
What is taxonomy?Taxonomy includes the study of naming and classifying animals and plants. By seeing the characteristic of a new organism, it is classified and put into kingdoms and groups.
Phylogeny and systematic are related to the evolutionary relationship between them, the family tree, and how an organism evolved over time.
Thus, Systematic has to do with the investigation of how a species changes over time and how they interact. The naming and categorization of plants and animals are known as taxonomy. Phylogeny is the study of family trees. These terms are related to each other.
