Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

why are the offspring of coral identical to the parent
they reproduce sexually so offspring have increased genetic variation
they reproduce asexually so offspring have increased genetic variation
they reproduce sexually so offspring have decreased genetic variation
they reproduce asexually so offspring have decreased genetic variation
Answer:
they reproduce asexually so offspring have decreased genetic variation
Explanation:
when an organism reproduces asexually, its offspring will look identical to the parent due to the offspring only receiving genes from one parent. I hope this helps!

1. Which of the following characteristics is possessed by invertebrates?
a) exoskeleton
b) endoskeleton
c) joint appendages
d) cephalization
Answer: a) exoskeleton
Explanation:
Well, many invertebrates – and all arthropods – have a protective external casing called an exoskeleton. This literally means ‘outside skeleton’ and its role is to cover the animal’s soft tissues and also provide a rigid structure to which the creature’s muscles can attach.
What is an example of a solute found in plasma?

Question 9 options:
Both of these
None of these
Relative dating
Radiometric dating
Scientists can determine the exact age of a fossil by a technique called Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.
In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.
Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.
Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.

Distinguish between dimorphic, polymorphic, and continuously variable traits.
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
Dimorphism is the condition of those species of animals or plants that exhibit two anatomical aspects or two different forms.When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.Continuously variable traits are those that show a continuous distribution of phenotypes.Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.

Which of the following correctly describes a graded potential?
Answer:
Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-none.
Explanation:
btw, where are the options?
The statement which correctly describes a graded potential is: amplitude of various sizes.
Graded potential refers to a temporary change in electric or membrane potential of a stimulus with respect to both its size and distance.
Amplitude can be defined as the maximum displacement of a wave when measured from its equilibrium position.
Thus, amplitude is measured vertically from an equilibrium position.Generally, a graded potential is directly proportional in amplitude to the size of the stimulus that is send as an input due to the following:
