How does Side chains determine the protein
Answer:
Because of side chain interactions, the sequence and location of amino acids in a particular protein guides where the bends and folds occur in that protein (Figure 1). The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

Where are the chromosomes/chromatids located during the four stages of mitosis?
Answer:
ExplanMitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide. Early microscopists were the first to observe these structures, and they also noted the appearance of a specialized network of microtubules during mitosis. These tubules, collectively known as the spindle, extend from structures called centrosomes — with one centrosome located at each of the opposite ends, or poles, of a cell. As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. This process ensures that each daughter cell will contain one exact copy of the parent cell DNA.ation:

Answer:
brings more leukocytes to the site of infection
Explanation:
Inflammation is an immune response to harmful stimuli such as injury or infections (i.e., pathogens). The inflammatory response is produced through the movement of plasma and leukocytes, also known as white blood cells, from the blood into the injured tissues. Leucocytes (i.e, granulocytes/neutrophils, lymphocytes, monocytes, etc.) are cells of the immune system that work together in order to eliminate the infectious agent by phagocytosis and/or to clean up injured tissues.
What is the net ATP gain at this stage of cellular respiration?
Answer: ok since i dont know specifics heres what i can give u
Most biochemists agree that in prokaryotic microorganisms, a total of 36 molecules of ATP can be produced during cellular respiration. In eukaryotic cells, the number is 34 molecules of ATP. Two molecules of ATP are produced as the net gain of glycolysis, so the grand total is 38 molecules of ATP (36 in eukaryotes).
Krebs cycle
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
2 ATP
The net energy gain in fermentation is 2 ATP molecules/glucose molecule. In both lactic acid and alcoholic fermentation, all the NADH produced in glycolysis is consumed in fermentation, so there is no net NADH production, and no NADH to enter the ETC and form more ATP.
Glycolysis breaks down glucose (6-C) into two molecules of pyruvate (3C), and also produces: Hydrogen carriers (NADH) from an oxidised precursor (NAD+) A small yield of ATP (net gain of 2 molecules)
this is what i can give u their are so many stages of cellular respiration i cant give all the details
2 ATP, 2 NADH, and 2 pyruvate are produced. Pyruvate digestion and the citric acid cycle produce more ATP and high-energy electron carriers.
What is cellular respiration?ATP, which can be utilized as a source of energy to fuel many different reactions throughout the body, is produced as a byproduct of cellular respiration, which is a sequence of chemical events that breaks down glucose. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three primary stages that are involved in the process of cellular respiration.
The end result is two molecules of ATP, two molecules of NADH, and two molecules of pyruvate. The later steps of the metabolic pathway, such as the digestion of pyruvate and the citric acid cycle, result in an increase in the amount of ATP and high-energy electron carriers that are created.

Explanation:
Dimples (D) is a dominant trait. If a woman with a genotype Dd and a man with genotpe DD have 8 children, how many of the children will likely NOT have dimples
Answer:
There will be no children without dimple and have only children with dimples.
Explanation:
Dimples in humans are characteristic that is influenced by the dominant allele of a gene which is represented by D and its recessive allele is d. So the DD which is pure and Dd which is a heterozygous condition for this characteristic and represents offspring or individual with the dimples. The pure condition of recessive alleles dd represents an individual without dimples.
Dd crosses with DD:
gametes will be D and d, and D and D.
D d
D DD Dd
D DD Dd
There are only two types of genotypes are produced that are:
DD - individual with dimples
Dd - individual with dimples
Thus, there will be no children without dimple and have only children with dimples.

Pistil and stamen are the reproductive organs of the plant. Stomata and guard cells are responsible for the gaseous exchange in plants and the xylem and phloem are responsible for conduction in plants. Thus, the correct option is D.
What are the different parts of plant?The different parts of plant consist of roots, shoots, leaves, flowers. All these parts contain different tissues and cells which are responsible for a specific function in the plant body.
The pistil and stamen are the reproductive structures in the plant cell. Pistil is the female part where stamen is the male reproductive part which are responsible for the production of new plants.
Stomata and guard cells are the specialized cells which are present on the surface of leaves. These cells are responsible for the exchange of gases and transpiration of water through the surface of leaves of plants.
Xylem and phloem are the vascular tissues which are responsible for the conduction of water and minerals in the plant body. These are made up of different types of cells hence, are known as complex tissues.
Anther and stigma are the parts of the male and female gametophyte. Anther contains pollen which have the male gamete whereas stigma is the part of the female reproductive structure on which the pollens land by pollination for the fertilization of the flower to form zygote.

Describe the pulmonary circulation by detailing the flow of blood from the right ventricle to the left atrium. Include the names of the blood vessels. Nadia
Answer:
Explanation:
Pulmonary circulation refers to a part of the circulatory system involve in carrying deoxygenated blood away from the right ventricle to the lungs and then carries oxygenated blood to the left atrium and ventricle of the heart.
Deoxygenated blood leave through the right ventricle by passing the pulmonary atrium. At the right atrium,the blood us pumped and move into the tricuspid valve into the right ventricle. The blood is then pumped from the right ventricle from the pulmonary artery. The pulmonary arteries carry deoxygenated blood into the lungs and here carbondioxide is removed and oxygen is use for respiration. Oxygenated blood is carried away from the lungs through the pulmonary veins which then return the blood to the left chamber of the heart completing the pulmonary cycle. Tye blood flow to the left atrium which is pumped to the left ventricle through mitral valve. From the left ventricle, the blood flow through the aorta through the aortic valve which distribute the blood to all part of the body and pulmonary circulation begins again.

Explanation:
1. A closer look - The food environment and food choices Some foods are nutrient-rich, while others are energy-rich yet nutrient-poor. Whole foods are the most nutrient dense because nutrients are left intact, which supports the best satiety cues (for example, an orange vs. orange juice), and overall confer the best outcome physiologically. Three-day diet records are often used to get an idea of an individual’s overall dietary habits to determine average daily caloric intake and how nutrient-rich the diet is. For the next three days, select the items that are richest in nutrients. Choose three items for each day’s lunch.
Answer:
Explanation:
Below is the diet of 3 days launch
Day 1:
Bacon
Peanut Butter (contains only peanuts) with bread
Day 2:
Plain Greek yogurt
Variety pack of Quaker instant oatmeal
Day 3:
Fruit on the bottom regular yogurt
Nature Valley granola bars
Since three day diet records can be used to assess an individual’s dietary habits, the food items consumed within this three days can then be thoroughly looked into to check the nutrient rich diet and the nutrient poor diet.
The nutrition rich diet should be maintained as they supply the body some important nutrients needed for its activities while the nutrients poor diet should be replaced with nutrient rich diet. Having fruits juice, yoghurt are good but can be supplement with whole food like cereals, vegetables, whole fruits for better body performance.
Important nutrients elements needed for the body should be checked and sought out from the daily intake when they are lacking diet containing such nutrient should be added.
What are these organisms called that have two halves that fit together like the top and bottom of a petri dish and get smaller and smaller over time when they reproduce asexually
Answer:
Diatoms
Explanation:
Diatoms are a group of algae especially found in the oceans (they also live in waterways and soils). The diatoms are known to generate about 25% oxygen on the Earth and 50% of the organic mass in the oceans. The shell of the diatom is composed by two halves or valves that overlap each other like petri dish halves, where the upper valve (epitheca) fits over the lower valve (hypotheca). Diatoms reproduce by both sexual and asexual (vegetative) reproduction. In vegetative reproduction, a single cell divides by mitosis and each daughter cell receives one valve.

White color mouse is more likely to survive and reproduce in the snowy environment. So, the correct option is (B).
What is Adaptation?Adaptation is defined as the behavioral or physical characteristics of an animal that help them survive better in their ecosystem which can be in the way they appear (camouflage) to avoid their predators. Different animals have developed different adaptations to survive in their habitats.
It is described as the process where a species or organism gradually adapts to its environment. Adaptation refers to how a species changes its body and behavior to adapt to its natural environment, where there are an estimated 8.7 million species currently living on Earth, found in a wide and varied natural environment, which range from frozen and desolate arctic to hot sand.
In the above example, white rabbits blend with snow and have extra thick fur for the cold, so they will likely to survive and reproduce more as compare to others.
