Based on the chart, describe the trends that can be observed in animal and plant fossils as they evolved over time. Use evidence from the chart to support your conclusions.
Based on the chart, we can conclude that the first vertebrates were fish. Moreover, the chart also shows that flowering plants are the last plant taxonomic group that emerged on Earth.
In this case, the chart suggests that the earliest vertebrates (fish) evolved during the Ordovician period.
The main animal groups that emerged during vertebrate evolution include (in this order) amphibians, reptiles, mammals, birds and finally humans.
Moreover, according to the chart, the latest major group of plants to evolve were flowering plants during the Cretaceous period.

whats released during cellular respiration
Answer:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

What is the benefit of this complementary nature of DNA?
-It helps in controlling the amount of protein produced by the cells.
-It helps in storing all the information required for the cell to function efficiently.
-It helps in the synthesizing of two new identical DNA strands from each parent strand
-It helps in the unwinding of DNA allowing for the formation of chromosomes during mitosis
The complementary nature of DNA rule ensures that only some particular base pairing are allowed and the DNA strands are complementary to each other.
The benefit of this complementary nature of DNA is that it helps in the synthesizing of two new identical DNA strands from each parent strand.
In DNA replication, the complementary nature of DNA ensures that following the production of new identical DNA strands, the composition of the new strands produced is intact and identical in composition.Learn more about the complementary nature of DNA: https://brainly.com/question/25674032

What are the two theories that are combined in the synthetic theory of evolution?
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
Using A to represent the allelesSince his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa). So for John to have an unattached earlobe, his father has to be either AA or Aa. Therefore John's genotype would be AaLearn more about genotype: https://brainly.com/question/22117

In the American Midwest, native seed crops goosefoot, sumpweed, and sunflowers were farmed about ________ yBP.
In the American Midwest, native seed crops goosefoot, sumpweed, and sunflowers were farmed about 6,000-1,000 yBP. These crops were used by early Amerindians as sources of food.
The native seed crops goosefoot, sumpweed, and sunflower were used by early Amerindian natives as food prior to the arrival of the squash, beans and maize from Mexico.
The sunflower is nowadays a worldwide extended crop used in intensive farming due to its high yield and high nutritional value.
The first domesticated plants in Illinois about 1800 years before Common Era include goosefoot (Chenopodium berlandieri) and sunflower (Helianthus annuus L.).

How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.
Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.

Answer:
Your topic (Nutritional blog post) explain the benefits of having proper nutrition and why should we do it. List down items we may sacrifice (ex. eating junk food) but the good effects this will bring us. Cite what will happen if we have healthy nutrition and back it up with evidence (Ex. A professional science study in 1993 has found that people who have healthy nutrition are less likely to disease [THIS IS ONLY EXAMPLE!]) Next, recommend some healthy foods or make a nutritional health diet for all the days in the week, balancing carbohydrates and giving the right amount of nutrition and calories.
