A pea plant's seed shape is round. What can be said about this trait?
A. It is a recessive trait.
B. It is the phenotype.
C. It is the genotype.
D. It is a hybrid.
Answer: A. It is a recessive trait.
Explanation: In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. The student is asked to predict the offsprings' pea shapes (both round and wrinkled; all round; all wrinkled; or can't predict). Because the allele that produces wrinkled peas is recessive, the offspring of this cross will all have wrinkled peas.

The cohesive forces of water
allows a thin film to form called____. This allows
water striders to be able to walk on top of water.
I NEED HELP NOWW
Answer:
1. Polar 2. Hydrogen bonding 3. Cohesion 4. Surface tension
Explanation:
1. Water is a polar molecules due to the presence of unbalanced charges in its covalent bond.
2. This unbalanced charges causes the molecules to be polar and thus form hydrogen bonds with nearby molecules due to their opposite charges. The hydrogen atom carries the positive charge while the oxygen atom carries the negative charge. The opposing charges thus causes hydrogen and oxygen atoms in nearby molecules to be attracted to each other.
3. This attraction of the water molecules to each other is called cohesion. Cohesion is the force of attraction between similar molecules and this force of attraction is called a cohesive force.
4. Since the water molecules are attracted to each other due to a cohesive force, this cohesive force causes a thin film to form called surface tension. Thus, surface tension is the ability of the surface of a liquid to resist external forces due to cohesive forces in its molecules and thus form a thin film.
Protists vary in structure and function more than any other group of organisms. However, here are some common traits: a.All have membrane-bounded organelles, and so are ___________________. b.Most are single-celled, or ___________________________. c.They get their food in several ways. Some contain chloroplasts and do photosynthesis, and so are considered __________________. Others ingest food particles and so are ____________________.
Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. ... After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm
Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?
Answer:
The presentation according to another circumstance is categorized in the following section.
Explanation:
Glucose constructs anomers because of the extreme involvement of flexible metal-carbon because that continues to exist as something of a monomer. However, when plastics are established, transformation is limited with glycoside formation of complexes among both anomeric carbon atoms.
Sucrose, besides obvious reasons, would be manufactured by glucose and fructose, which have been connected by something like a glycerol backbone involving glucose carbon atom as well as fructose. The mechanism including its creation of anomers even by movement through carbon becomes called "Mutarotation" Sucrose doesn't always show mutation.What is erosion?

Read this speech given by US Secretary of Defense Chuck Hagel on Veterans Day 2014. What is the purpose of the speech?
Every year, we set aside Veterans Day to honor all the men and women who’ve served our country in uniform. We celebrate veterans from generations past. We welcome a new generation of veterans home from war. And we thank our future veterans, still serving at home and abroad.
They are securing our nation through their engagement across the globe. Some are in West Africa, contributing to the global effort to stop the spread of Ebola. Some are in the Middle East, working closely with our coalition partners in the fight against ISIL. And some are in Afghanistan, where next month the United States will responsibly end the longest war in our history.
For our troops serving around the world today, and those transitioning out of the military, our obligations are only beginning. Taking care of them, and their families, is a sacred responsibility we must always uphold.
Let’s celebrate them by telling their stories. Let’s help those who need it, while supporting their strength and resilience. And let’s honor our veterans by creating new opportunities for them to contribute after their service, so they can continue making a difference in the world.
To all our veterans—thank you. Thank you for everything you’ve done for our country. You’re among the best our nation has to offer. God bless you and your families, and happy Veterans Day.

while mutation is random, natural selection is not. In your own words, explain how this is possible
Answer:
Mutation is a alteration in the DNA sequence in a gene during cell divison iwhere gene is coded mitakeny or due to the error. Mutatio is a random process as it can not be determind or known befor bthechange in sequence what gene or DNA would be effected by it or what genes would be transfer from the parents.
Natural selection is a process where some of the traits that are helpful in the surviving and increasing the number of individuals in a population and transfer from one generation to other according the adaption and change over the long timeline. Thus, it is not random and based on the traits that are helpful in a environment or for the survival of
What is the danger posed by introduced species? *
O Non-native species might have no natural predators in their new environment
Non-native species can occupy space and crowd out indigenous species
Non-native species might prey on native species threatening extinction
All of these are dangers posed by introduced species
There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
Answer: A. Environmental drivers plus genetic variation in the population result in natural selection
Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.
There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.
