Answer:
Monocots, such as corn (right), have one cotyledon, called the scutellum; it channels nutrition to the growing embryo. Both monocot and dicot embryos have a plumule that forms the leaves, a hypocotyl that forms the stem, and a radicle that forms the root.
Structures that are anatomically similar because they were inherited from a common ancestor are called ____________ structures.
Answer:
Homologous structures
Explanation:
Physical features may be considered homologous or analogous, but what does this mean? Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats

William has Brown eyes. Is it likely that both of his parents have blue eyes?
Answer:
Brown eye genes are more dominant than blue or green eye gene. He most likely got the brown eye gene from his mother. People don't necessarily have blue eyes just because their parents do. Both parents are probably heterozygous for blue eyes.
Explanation:
Answer:
No
Explanation:
Blue eyes are a recessive trait while Brown eyes are a dominant trait. Two recessive traits = the recessive trait. One dominant trait + one recessive trait = the dominant trait.

what are the cons of fetal stem cells
Answer:
The research is unethical(fetal stem cells) since the blastocyst, an unimplanted human embryo at the sixth to eighth day of development, is destroyed during the stem cell extraction process.
Answer:
Embryonic Stem Cell Disadvantages
1. Difficult to differentiate uniformly and homogeneously into a target tissue. 2. Immunogenic—ES cells from a random embryo donor are likely to be rejected. after transplantation.
Explanation:
The main disadvantage with embryonic stem cells is the way that they are acquired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.

Add another bar to the chart that would represent Han
chinese at low altitudes. Pay attention to the height of
the bar and provide a short explanation for your choice.
Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans since Han Chinese live at lowlands.
What is the role of natural selection in evolution in Tibetanscompared to Han Chinese?Tibetans and Han Chinese are thought to originate fro. same ancestors.
However, while the Han Chinese lived in lowland areas, Tibetans split off drom the Han Chinese about 2750 years ago and went on to live in high altitudes.
Natural selection helped Tibetans to evolve to adapt to high altitudes with several mutations occurring in their genes which are mostly related to use of oxygen by the body.
Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans.

13. Which of the following statements about complete metamorphosis is TRUE?
The physical form of the young animal is completely different than the physical form of the adult.
The adult form of the animal is similar to the young animal.
O All organisms that undergo complete metamorphosis are a caterpillar at some time.
Only arthropods undergo complete metamorphosis.
Answer:
The first one true.
Explanation:
Metamorphosis usually starts with the baby being completely different from the adult. Take a frog for instance. Righttttt
the second couldn't be because then that wouldn't metamorphosis...just growth..
not all organisms that metamorphise are caterpillars ..as i said..look at the frog:)
If 15% of a particular DNA strand are nucleotides containing cytosine, what percentage of the DNA molecule would contain thymine
Answer:
35%
Explanation:
To make a DNA helix, two DNA strands are required. They are connected by the nitrogenous bases on each strand. Each type of nitrogenous base is complementary to another type: cytosine (pyrimidine) pairs with guanine (purine) and thymine (pyrimidine) pairs with adenine (purine). This means they only bond with their pair.
For every cytosine, there must be a guanine bonded to it. So, if 15% of the strand is cytosine, another 15% must be guanine.
Since,
15% + 15% = 30% and 100% - 30% = 70% ,
30% of the DNA strand consists of the cytosine-guanine pair and 70% of the DNA strand consists of the adenine-thymine pair.
Since,
70% / 2 = 35% ,
70% is made up of equal parts adenine and thymine, 35% of the DNA strand must contain thymine.

Why is a single base insertion or deletion likely to drastically change how the rest of the genetic code is read?
The genetic code is of utmost importance as a slight change in it can change the characteristics of an organism. Just like that base insertion or deletion can cause shifting of frame and can result in a change of the nucleotide sequence causing mutation.
What are the types of mutation?Mutation is any change in the genetic sequence that can lead to changes in the genome.
It can be of the following types:
Germline mutation: In gametes, germline mutations occur. Other cells in the body experience somatic mutations.Chromosomal alterations: these are mutations that change the structure of the chromosome.Point mutations: it affects only one nucleotide.Frameshift mutations: these are nucleotide additions or deletions that cause a shift in the reading frame.Thus, base insertion or deletion likely to drastically change how the rest of the genetic code is read as it result in frameshift mutation.
