How could one determine if two
unidentified organisms share a common
ancestor?
Answer:
Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.
Explanation:
DNA
They can look at the DNA it's the most common one.
There are 4 pieces of evolution and they are
Fossils , Geography , Embryos / DNA , Anatomy
Fossils: Physical remains of species , Determine age, location, environment
Deeper layers = older
Geography: Proves species share common ancestors, depending on where
they live
DNA: BEST evidence because it’s the MOST ACCURATE
Similarities in the early stages of development
Similarities in DNA
More similarities = closely related
More differences = not related
Anatomy: Compare body parts of different species to see how they evolved
3 different structures:
Homologous (same structure, different function)
Analogous (similar structure, different organisms)
Vestigial (body parts that no longer serve a purpose)
All of that are in evolution

Describe the process of absolute dating as it relates to igneous rock and the fossil record.
Answer:
Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ... When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.
9. What is the difference betwen climate and weather?
Answer:
Climate is the long-term weather, like it is usually sunny in Florida,
Weather is the weather that you see every day, such as rainy.
Explanation:
Answer:
Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location.
Explanation:
If water was removed from a plant's environment what would happen to the plant's glucose production?
Answer:
It would cease
Explanation:
If water is removed from a plant's environment, the plant's glucose product will cease. This implies that the plant will stop producing glucose.
Water is an essential ingredient for the production of glucose by plants. During the process of photosynthesis, green plants manufactures their food in the presence of sunlight. The water combines with carbon dioxide to produce glucose oxygen gas using sunlight energy. Without water, this reaction will not be possible to take place. Therefore, the production of glucose stops when there is no water.Summarize in 2-3 sentences, how an RNA vaccine works to help protect you against

It is advantageous for a predator to prey exclusively on a single prey species.
Answer:
Assuming this is a true/false question, the answer would be false.
If a predator only preyed on one species, it would be at a disadvantage if the prey it feeds on gets wiped out in that region.
Therefore, your answer is False.
The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)
Answer:
The no. of heterozygous carriers = 0.0392
Explanation:
From the given information:
The incidence of this recessive disorder i.e. q² = 1/2500
q² = 0.0004
q = 0.02
From Hardy Weinberg's Equilibrium.
p + q = 1; &
p² + 2pq + q² = 1
∴
p + 0.02 = 1
p = 1 - 0.02
p = 0.98
So, the numbers of heterozygous carrier 2pq is:
= 2 × 0.98 × 0.02
= 0.0392

is mitosis genetically identical
Answer:
Yes, mitosis is genetically identical.
Explanation:
when mitosis happens, the cells replicate their DNA so when the cell divides in 2, each cell contains the same chain of amino acids so yes the process creates 2 genetically identical cells
A scientist is treating rice plants with a chemical that causes mutations. What is the possible benefit of this treatment? A. clones B. transgenic plants C. increased genetic variation D. increased hybridization
Answer:
Explanation:
Its either B or C, look closely at the question and at the answers, you can narrow it down from then.
A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.
What is mutation?A mutation is a change in the DNA sequence that makes up a gene. It can result from errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.
Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.
Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.

Which best explains the role of plants in the nitrogen cycle?
Answer:
Assimilation
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
