Answer:
Closed systems do not exchange energy with the environment, while open systems do.
Explanation:
The cause of this is because closed systems are made up of an insulator that surrounds them and isolates them from the environment or adjacent environment.
This insulation prevents heat from being taken in or transferred from the surroundings as in the case of open systems.

Use the abbreviations you chose for Questions 7-10 to answer Questions 11-12. a. If you were writing about Homo habilis and Homo neanderthalensis at the same time, would you need to change your abbreviations?
Answer:
The correct answer is - no.
Explanation:
In the Homo habilis and homo neanderthalensis the genus name of both species are the same so and can easily be depicted as an individual without confusion.
The correct abbreviation for Homo habilis is H. habilis and for Homo neanderthalensis is H. neanderthalensis. Both are referring to the same species as indicated by H. which is homo.
Thus, there is no need to change the abbreviation.
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.

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.
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:

nflammation ________. Inflammation ________. is caused by bacterial activity to enhance the spread of disease slows the healing process with swelling that can impair bodily function is caused by viral activity to enhance the spread of the disease brings more leukocytes to the site of infection
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.

Hope this helps
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.
Therefore, the correct option is D.

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.
Thus, white color mouse is more likely to survive and reproduce in the snowy environment. So, the correct option is (B).

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.

Explanation:
A 42-year-old male reports pain in his lower back for the past month. The pain sometimes radiates to his left leg. In determining the cause of the back pain, based on your knowledge of anatomy, what nerve roots might be involved
Answer:
Sciatic nerve.
Explanation:
The sciatic nerve is the longest and thickest in the anatomy and it originates from the sacral plexus. The sciatic nerve and its nerve branches allow movement and sensation (motor and sensory functions) in the thigh, knee, calf, ankle, feet, and fingers. When the pain exceeds the lumbar area and reaches the lower limbs, we speak of radiating lumbar pain. If the pain spreads from the lower back to the heel or foot, down the back or side of the thigh, we call it lumbosciatica (or just sciatica). Its presence suggests injury to the nerve roots that come out of the lumbar spine and carry the sensation or orders to contract the muscles to the lower limbs through the sciatic nerve.
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.
