Why does the blood in your veins just under your skin look blue?
Answers
The veins themselves are not blue, but are mostly colorless. It is the blood in the veins that gives them color. Furthermore, the blood in human veins is also not blue. Blood is always red. Skin scatters a lot of the red portion of white light before it can reflect off the blood, leaving the blue light to reflect off the blood and back to our eyes. (Baird 1)
In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin.
Answer:
They appear blue because blue light is reflected back at our eyes. Blue does not penetrate human tissue as well as red light does. Therfore if the vein is closer to the surface, it will most likely appear blue
Explanation; :Blue does not penetrate human tissue as well as red light does. Therefore if the vein is closer to the surface, it will most likely appear blue

Organisms can be made up of many cells, which could be arranged into tissues, which can make up organs, organs can be part of an organ system. These are parts of the body.
Organisms can be unicellular (e.g., bacteria and protists) or multicellular (e.g., fungi, plants and animals).In multicellular organisms, cells are organized into tissues (e.g., connective tissue) that play specialized functions.In turn, two or more tissues can be organized to form organs (e.g., liver, kidney) that perform specific functions for the body. Finally, organs are arranged into systems that work together to carry out a particular function for the body. For example, the urinary system is responsible for cleaning and filtering the blood of waste products.The organ systems include the cardiovascular system, respiratory system, digestive system, nervous system, endocrine system, integumentary system, skeletal system, muscular system, lymphatic system, urinary system, and reproductive system.In conclusion, the correct levels of organization (from smallest to largest) are cells >> tissues >> organs >> organ system.

5. A solar cellis a device that collects energy from the sun to make electricity. What part of a plant is most similar to a solar cell and how does it function to provide energy? 6. . How does cell structure suggest cell function?
Answers
Answer:
5. The part of a plant that is most similar to a solar cell is the chloroplast. Chloroplasts are specialized organelles found in plant cells that contain chlorophyll, a pigment that absorbs sunlight. They function in photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into glucose (a form of energy) and oxygen.
In photosynthesis, chloroplasts capture light energy from the sun and use it to generate chemical energy in the form of glucose. This process occurs in the thylakoid membranes within the chloroplasts, where chlorophyll molecules absorb light energy and convert it into chemical energy through a series of complex reactions. The chemical energy stored in glucose is then utilized by the plant for various cellular processes, including growth, development, and metabolism.
So, just like a solar cell converts sunlight into electricity, chloroplasts in plants harness sunlight to produce chemical energy in the form of glucose.
Cell structure provides important clues about its function. The specific organization and components of a cell determine its capabilities and the tasks it can perform within an organism.
For example, the presence of specialized organelles like mitochondria suggests that a cell is involved in energy production, as mitochondria are responsible for cellular respiration, the process that generates ATP (adenosine triphosphate), the energy currency of cells.
Similarly, the presence of ribosomes indicates that a cell is involved in protein synthesis, as ribosomes are responsible for assembling amino acids into proteins.
The shape and structure of a cell can also suggest its function. For instance, nerve cells have long, branching extensions called dendrites that enable them to receive and transmit electrical signals over long distances. Muscle cells are elongated and contain specialized proteins that allow them to contract and generate force for movement.
Overall, the structure of a cell is intricately related to its function, and by examining its components, organelles, and shape, we can gain insights into the specific roles and capabilities of different cell types within an organism.

If the half-life of carbon 14 is about 5730 years, then a fossil that has one-sixteenth the normal production of carbon-14 to carbon-12 should be about how many years old?
Answers
A fossil that has one-sixteenth the normal production of carbon-14 to carbon-12 is most likely very old. This is because carbon-14 has a relatively short half-life of 5730 years, meaning that after this amount of time, half of the amount of carbon-14 in an organism or object would have already decayed.
Since the fossil being discussed has one-sixteenth of the normal production of carbon-14 to carbon-12, this would suggest the fossil is at least 8 times the half-life, or 45,840 years old. Carbon-14 is necessary to measure the age of an object, and due to the fact that this fossil has only one-sixteenth of the normal carbon-14, it can be deduced that it is very old.
It is also possible that the fossil is much older than this calculation, but because of the short half-life of carbon-14, any other amounts which may have been present before the 45,840 year mark has decayed away. In conclusion, a fossil that has one-sixteenth the normal production of carbon-14 to carbon-12 is estimated to be 45,840 years old or older.

The most permeable capillaries, which contain fenestrations and large intercellular clefts, are called __________.
Answers
The most permeable capillaries, which contain fenestrations and large intercellular clefts, are called Sinusoid capillaries.
Venules and arterioles are connected by capillaries. They enable the fluid between the blood and tissue cells as well as the exchange of nutrients and wastes. This exchange takes place by pinocytosis, which means "cell drinking," and passive diffusion. For proteins and certain lipids, pinocytosis is employed. White blood cells can also enter the surrounding tissue through intercellular connections to heal damage and fight infections. Cancerous cells that are spreading employ this channel as well.
Due to the enormous intercellular clefts between their endothelial cells, sinusoid capillaries are the most permeable type of capillary. These capillaries enable the passage of big molecules, including blood cells, into the tissue around them. The liver, bone marrow, spleen, and adrenal medulla all contain sinusoid capillaries.

Have you ever noticed that fruit flies don’t all look alike? If you look closely, you may see that they can have red eyes or white eyes.
Like all living organisms, fruit flies grow and reproduce. In Lesson 3.01, you learned mitosis is the process by which a cell divides into two daughter cells, each of which has the same number of chromosomes as the original cell. In Lesson 3.02, you were introduced to meiosis, the process by which organisms produce gametes. In this investigation, you will simulate mitosis and meiosis in fruit flies. Be sure you have fully investigated lessons 3.01 and 3.02 before beginning this assignment.
Materials:
16 pipe cleaners of 2 different colors and 4 matching lengths
String
O-shaped cereal
Marker
Procedure:
Part 1: Modeling Mitosis:
Copy the mitosis chart and add your name to the presentation. The circles you see represent a fruit fly body cell in different stages of the cell cycle.
Take out your pipe cleaners (to represent chromosomes). One color will represent the chromosomes inherited from the mother and one color represents the chromosomes inherited from the father. Use the same length of pipe cleaner for homologous pairs. You should have two sets of four different lengths of pipe cleaners.
Begin by assembling a diploid set of chromosomes for a fruit fly as they exist during most of interphase. A diploid set contains pairs of homologous chromosomes. Each chromosome at this point will be a single strand. You will have an extra set of each length and color left over. Here is a diploid set: Take note:
What is the diploid number of chromosomes in a fruit fly?
How many homologous pairs of chromosomes does a fruit fly have? (review this video for a review of chromosome numbers)
In late interphase, the amount of DNA doubles. That means each chromosome now doubles. Select a matching pipe cleaner (same length and color) for each chromosome and slide both through a piece of cereal. You now should have a set of eight doubled chromosomes arranged in homologous pairs.
Review the mitosis diagrams page 3 of Lesson 3.01 and move the chromosomes through the rest of the steps on your board.
Take a picture of each stage and place it in the appropriate circle in your diagram. Example:
This is a sample image of the # of chromosomes for a Spider Mite, not a Fruit Fly.
Fill in Tables 1 and 2 with the correct information
Table 1: Cell cycle and mitosis in fruit flies

A diploid set of human chromosomes contains 23 homologous pairs (46 chromosomes)
Table 2: Cell cycle and mitosis in humans
Step Number of
Cells Number of chromosomes in
each nucleus Number of homologous pairs
in each nucleus
Interphase
Cytokinesis
Part 2: Modeling Meiosis:
Meiosis is the process of producing sex cells with a haploid set of chromosomes. Haploid means half the number of chromosomes as the original cell. A haploid cell contains one chromosome from each homologous pair.
Copy the meiosis chart and add your name to the presentation. The circles you see represent a fruit fly body cell in different stages of Meiosis.
Begin by assembling a diploid set of chromosomes for the fruit fly as you did in Part 1. Place the chromosomes, in homologous pairs, in the first nucleus on your chart.
Like mitosis, before meiosis begins, the chromosomes double. Add a similar pipe cleaner to each chromosome and attach it with a piece of cereal as you did in part 1.
Unlike mitosis, which only has one cell division, meiosis has two divisions. Using the meiosis diagram Module 3 as a guide and move your chromosomes through Meiosis I and Meiosis II, taking pictures along the way.

Individual fruit flies (Drosophila) typically have orange-red eyes. However, some mutant versions have white eyes and lack the red pigment. The fruit fly's reaction to light is altered by these eye color changes.
What are the different eyes color in fruit flies?A new study using fruit flies supports one benefit of sex: It favors advantageous mutations. A female who reproduces asexually transmits all of her genes, whereas a sexually active female only transmits half of her genes.
Wildly bred fruit flies occasionally have crimson eyes. A recessive gene causes brown and sepia eyes, which can only appear when two sepia-eyed flies mate.
Therefore, fruit flies with white, vermilion, and cinnabar eyes are mutations that are far less frequent.
