Answer:

D) Krebs' cycle

Explanation:

The stage of respiration shown is pyruvate oxidation. This is the intermediate stage between the first and second stages of aerobic respiration.

The first stage is glycolysis, which is the breakdown of glucose into two molecules of pyruvate. After pyruvate oxidation, the next stage is the Krebs cycle. The Krebs cycle is a series of reactions that release energy through  oxidation of acetyl-CoA.

What is genetic variation?

The difference in DNA between individuals or between populations is referred to as genetic variation.

Mutation and genetic recombination are two of the many sources of genetic variation. Although mutations are the ultimate source of genetic variation, other mechanisms such as genetic drift also contribute to it.

Heredity, also known as inheritance or biological inheritance, is the transmission of traits from one generation to the next.

Each of your parents has two copies of each of their genes, and each parent passes on only one copy to you.

Many of your characteristics, such as hair and skin color, are determined by genes that are passed down to you.

Thus, the correct option is B.

When does facilitated diffusion occur?

Answers

Answer:

The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.

Explanation:

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins.

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Which of the following occurs just before the cell enters the G2 stage of
the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides

Answers

Answer:

DNA replicates

Explanation:

S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration

How does an atom become a positive ion?
A. It loses an electron,
B. It loses a neutron,
C. It gains an electron
D. It gains a neutron,
SUSAN

Answers

The answer is A it loses and election
Ionization or ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion. Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules and ions, or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected. So it is A

Which statement below best describes the purpose of meiosis in creating gametes?

Answers

The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.

What is meiosis?

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).

The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.

In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

Scientists would like to use a sample of size 200 to estimate the proportion of the approximately 5000 pine trees along the highway that have been infested. It is not practical to use an SRS in this setting. A possible alternative would be to use the first 200 pine trees along the highway as you enter the park. Why isn't this a good idea? Case ScenarioOver the past four years, the LSS organization, a nonprofit organization headquartered in Minneapolis, MN, has become renowned nationally for its Camp Noah project. Following floods, tornadoes or other weather emergencies, children lose their daily routine, their schools and oftentimes their homes. Parents are often stressed and unavailable during emergencies, and children have few resources to help them understand their situation. In Camp Noah, volunteers with skills in child psychology and counseling meet in a two day support group environment with children in flood ravaged areas. They encourage the children to share their stories and develop important resiliency skills and learn how to cope emotionally with the disaster.Due to the need for such services, LSS has developed a training system that lets them partner with resource organizations located near flood or tornado areas. They have partnered with many local organizations around the U.S. to train, equip and empower volunteers to staff local camps attended by children during their summer vacation. LSS also provides pre-packaged Camp Noah supplies that range from workbooks, crayons and puppets to a quilt for each child.Recently, powerful rainstorms in southeastern France triggered flash flooding that displaced more than 1000 families, and left 200,000 people without electricity for more than two weeks. City officials in France called the LSS Director of Camp Noah Services, Chris Walker, and asked if she could provide training and equip 20 volunteers in southeastern France to deliver the Camp Noah curriculum to up to 500 children. The French officials have asked that a decision to proceed be made within 2 weeks, and that the training and they want the equipment be delivered 6 weeks after the decision is made. Chris Walker wants to help but isnt sure how to start. Currently, Camp Noah supplies are all written in English, and the counselor training documents are only written in English as well. The floods occurred in an area of France that has few English speakers.You are a contract employee who has been engaged to help LSS because you speak French fluently and because you are an expert, experienced project manager with great interpersonal skills. Your job is to assist the director, Chris Walker, during project initiation. If the project is approved, you may be asked to lead the remainder of the project as well. You and Chris have been in meetings together all day discussing the opportunity for a French Camp Noah. Youve been listening very carefully and asking dozens of questions about the potential effort. Now, youre ready to get started and put your considerable project management skills and knowledge to work.Questions based on above scenario and answer need to be 1/2 page long:1. Is this (or will this be) a project or operations? Justify your choice.2. What process group is this project currently in? How do you know?3. As an experienced project manager, you are aware that analyzing the environment in which a project operates is critically important. Select two (2) OPA and two (2) EEF that you believe are important to understand for this project. Apply these to the case scenario and justify why the four items you selected are important. 4. Once the decision is made to proceed with the project, Chris Walker, the director, will need to select a project manager. You know that LSS is a strong-matrix org. What does this mean in terms of how the project will be conducted and the role of the project manager? (5. You and Chris Walker, the director, will work on trying to define what project success will look like as you define the project objectives.
