Which of the following is not one of the steps through which scientists hypothesize simple cells were produced? (3 points)
The biotic synthesis of small inorganic molecules
The joining of small molecules to form macromolecules
The origin of self-replicating molecules
The packaging of macromolecules into protocells
Answer:
The biotic synthesis of small inorganic molecules
Explanation:
The biotic synthesis of small inorganic molecules is not one of the steps through which scientists hypothesize simple cells were produced.
What do you mean by a Cell?A cell may be defined as the smallest structural and functional unit of life in the living entities.
Biotic synthesis of small inorganic molecules lacks the presence of essential elements like hydrogen and carbon. In the absence of such important biomolecules, simple living cells are impossible to synthesized.
Therefore, the correct option for this question is A.

how are karyotypes made?
Answer: A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.
Explanation:
Karyotypes are prepared from mitotic cells that have been arrested in the metaphase or prometaphase portion of the cell cycle when chromosomes assume their most condensed conformations. A variety of tissue types can be used as a source of these cells.

What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

Consider the following scenario: A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations. What is the main selective pressure in this scenario?
leg length
insect population
drought
fish population
fish population
cuz i know :0
The main selective pressure in the given scenario will be on the fish population. Thus, the correct option will be D.
What is Selective pressure?The selective pressure can be defined as an evolutionary force that causes a particular phenotype to be more favorable in certain environmental conditions than other phenotypes. Selective pressures are the considered forces which can drive the evolution through the process of natural selection. Some phenotypes are more favorable than other phenotypes, depending on the external conditions.
Selective pressures can be detrimental or beneficial to certain phenotypes present within a population. The four main types of selection pressures are the biological factors, such as the predation and disease, the availability of resources, the climatic conditions, and the competition between different species.
Therefore, the correct option will be D.

Which term best describes two predators living in the same habitat who feed on the same prey?
A.coexistence
B.mutualism
C.competition
Answer:
The answer is C, competition
Competition refers to the interaction between the organisms to seek or feed on the same resource.
The term that best describes the two predators living in the same habitat feeding on the same prey is competition.
Competition can be defined as:
Competition in an ecosystem or habitat will take place when the ecological niche of organisms overlaps as both organisms try to use the same resource. In habitat, the predators feeding on the same prey will have competition, as the predators will fight for food, nutrients, and a source of energy to survive. Competition can be caused among animals due to food, space, and shelter.
Thus, the correct answer is Option C.
