A
Explanation:
According to scientists, all of the bodies in the universe came from a rotating cloud of gases and dust about
billion years ago.
O 3.5
O 2.5
O 4.5
O 1.2
It's either 3.5 or 1.2
There would be more evidence spread out through space to be noticed by scientists and it seems like a stretch to go as far back as 4 billion years ago.

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 occurs after sunlight is absorbed by a chloroplast?
A. The light energy is used for the production of a carbon dioxide and water,
B. The light energy is converted to a glucose molecule
C. The light energy is converted to green light, giving the leaf its color.
D. The light energy is distributed throughout the cell to be used by basic cell functions.
Answer:
B
Explanation:
A cannot be true as photosynthesis requires carbon dioxide and water and uses light energy to break bonds and form oxygen and glucose
C cannot be true as chloroplasts contain chlorophyll which gives the cell its green colour by not absorbing green wavelengths of white light
D is not right as I do not believe photosynthesis is a basic function
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.Which of these causes the day/night cycle on earth

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.

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.

In an experiment, three plants of the same species were grown in each of six identical pots. The heights of the plants were measured when growth began. Each post was watered everyday with salt solutions of different concentrations. The data for the experiment are shown on the table
1.) state the effect of increasing the percent of salt in the solution used to water the plants on the average final height of the plants in groups A through D
2.) state one way diffusion was involved in the cause of death of the plants in groups E and F.
Answer:
See the answer below
Explanation:
1. The data from the experiment shows that as the percentage of salt in the solution used to water the plants increased, the growth rate of the plants decreased. As the percentage increased from A to D, the change between the average initial and the final heights decreased, meaning that an increase in the percentage of the salt in the solution used to water the plants had a negative impact on the growth rates of the plants.
2. Due to the solutions used to water the plants in groups E and F being more concentrated (hypertonic) to that of the cell sap of the plant, water molecules diffused out of the cell sap to the ambient solution. As time goes by, the plants lose too much water, become wilted, and died off eventually. Instead of water molecules to keep diffusing into the plants in order for them to grow, the reverse was occurring and this led to their death.

8. The atomic number of an element is
a) equal to the number of isotopes of that element
b) is equal to the number of protons in the nucleus of an atom of that element
c) is equal to the number of neutrons in the nucleus of an atom of that element
d) is equal to the number of particles that can be found in the nucleus of an atom of that
The correct answer is B) is equal to the number of protons in the nucleus of an atom of that element.
Explanation:
The atomic number, which is represented by the letter Z, refers to the number positively charged particles known as protons. This characteristic is key in chemistry and related areas because based on these features elements have different properties and are named. For example, an atom of nitrogen element always contains 7 protons, while one of the gold contains 79 protons. Moreover, this property is not related to the number of neutrons because atoms with the same atomic number might differ in the number of neutrons, which leads to isotopes of the same element.

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.
