Hello,
Find attached my lab 4 worksheet I need help on it. You will find everything you need in this worksheet. Pleas watch the 2 link provided in the paper before starting so you can got it right. It pretty straight and easy it wont take more than an hour.

This is a graded discussion: 14 points possible
due Oct 14
Maternal and Child Health – Read a Paper Excerpt – Group 1From Fal21_BIOL011_73132No unread replies.22 replies.
We will be reading a paper about disparities in maternal and child health. Before you get started, please watch this video for some background:

For this post, each person in your group will become an expert on one section of the paper:
Beck, A.F., Edwards, E.M., Horbar, J.D. et al. The color of health: how racism, segregation, and inequality affect the health and well-being of preterm infants and their families. (Links to an external site.) Pediatr Res 87, 227–234 (2020). https://doi.org/10.1038/s41390-019-0513-6
For your initial post, you are only reading one section for this assignment; however, it may be helpful to read the article abstract (Links to an external site.) to give you a general summary of the study.
Links to each section:
Introduction
Risk Assessment WORKING ON THIS SECTION
Quality of Care
Socioeconomic Disadvantages
Discussion
Post Requirements:This assignment requires two posts, each completed individually.
First Post
Each person in your group will read one of the five sections listed above, selected on a first-come, first-serve basis. It is strongly recommended that you make a placeholder post to avoid multiple students reading and posting about the same section. You may reply to your placeholder post with your responses to the prompts.
Title your post with your chosen section (e.g., Introduction, Risk Assessment, etc.), then answer the following:
Write a 5-6 sentence summary of your section of the article. What were the main takeaways? If you use any vocabulary words, be sure to define them.
Find a line/concept (“golden line”) within your section of the article that you found interesting, resonated with you, or changed your thinking on this topic (you may copy/paste the text into your discussion post). In 2-3 sentences, explain the significance of your selection.
Based on the reading of your section, what are two questions you have? These may be something you need clarification on, technical questions, questions about the diets, methods, or broader questions about the article. Try to avoid posing q

Write a topic and replay for other 2 students posts.
Please post in minimum 500 words about your topic. Aspects to cover will depend on your topic, but here are some suggestions:If a disease, what is its cause, how does it manifests, prevalence, risk factors, prevention, treatment etc.
If a type of organism, what is its classification, characteristics, habitat, its role in the ecosystem, any human use (or abuse), importance etc.
If a substance, what is its chemical nature, where is it obtained from (or how is it made), how does it act, its relevance, use etc.
If a procedure, what is it based upon? What is it used for, what is its relevance?

Provide 2 peer-reviewed references or reputable websites. See the CRAAP test
Attach/insert one picture/diagram illustrating your topic.

The other files that I attached just to help writing and I will also attach a video to watch.

You can add your own thoughts. But it must be ensured that it is not plagiarized in Turnitin
Format:
(1) Single-spaced, (2) Arial/Helvetica 11 pt, (3) 1” margins, and (4) justified.
Each answer should NOT exceed one page. Please be concise; you don’t have to fill the entire page if not necessary.
References and figures are optional and NOT included in page counts.
Include name on every page (top left).

Key Points for Grading:
Comprehensiveness (the breadth and depth of understanding of lecture material)
Logic (quality of reasoning)
Clarity (concise and clear)

Tips:
Organize your thoughts and provide a logical answer with a good flow.
Make your points as direct as possible. Avoid excessive language.
Write simple and clear sentences. Long answers are not necessarily good answers.
Be consistent and accurate with your use of terminology.
Use active, rather than passive, voice. For example, write “diet is a key factor in successful aging,” not “successful aging can be influenced by diet.”
Spell out all acronyms on first reference.

Question number [point value]
1. [4] Describe two ways by which DNA polymerase ensures that the correct base is added to the growing polynucleotide chain during replication, addressing what these mechanisms have in common, and how they differ. What is the contribution of these mechanisms toward the overall fidelity of DNA replication? (MLO 4.1)
2. [4] Briefly summarize the palm, thumb, and finger domains of DNA polymerase, and explain how they contribute to replication. What is the role of the metal ions in the palm’s activity?(MLO 4.2)
3.[4] What prevents ribonucleotides from being incorporated into the growing DNA strand during replication of the genome? In what aspect of replication are ribonucleotides used?(MLO 4.1

How are they similar? What are the three major algal phyla? What are the differences between these groups?
Marine algae and plants are important in marine habitats. Discuss three reasons why this is the case. Be sure to include examples to highlight your major points.
Sponges were not always taxonomically placed in the Kingdom Animalia. Why are sponges different from the rest of the animal kingdom? What are the key characteristics for the organisms in the Phylum Porifera? What are the 3 major subgroups, and how are they different?
Lastly, organisms cannot, will not, do not live in isolation. All life depends on other organisms (either directly or indirectly) rely on others for survival. What are the animals that consume sponges? Describe one way sponges contribute to the organism diversity of their habitats (this will require some investigation on your part)? Be sure to use examples in your response.

Describe the molecular structure of lipids, their physical properties, and the roles they play in cells.
2.Use the properties of phospholipids to explain how they spontaneously form selectively permeable membranes.
3.Predict how gradients can affect the movement of water and solutes across a membrane.
4.Compare and contrast how membrane proteins help substances cross a cell membrane via passive and active transport.

Being healthy means that you are physically, mentally, and emotionally healthy. Believe it or not all of these require some level of energy. We just learned that ATP is the energy currency of the cell so an increase or decrease in any of these areas will reflect in ATP usage. Consider the following set of questions and answer them using at least 250 words.
Do you consider yourself a healthy person? Why or why not? What would you change if you could?
Do you eat healthy? What are the major stumbling blocks to being able to maintain a healthy diet?
How does exercise (physical health) effect your mental and/or emotional health?
How would an increase in physcial exercise effect the amount of adenosine triphospgate used? How would your body respond to how much ATP it would make?
