A. cell wall
B. chromosome
C. cytoplasm
D. nucleus
Answers
Answer:
The answer would be "C," as all of the organelles are suspended in the cytoplasm of a cell. The cytoplasm is extremely important as it protects genetic material and prevents organelles from colliding.

What is the source of the carbon dioxide that is used in photosynthesis?
sunlight
the soil
the atmosphere
the plant
Answers
Answer:
THE ATMOSPHERE
Explanation:
The atmosphere is the source of the carbon dioxide that is used in photosynthesis. Hence option c is correct.
What is photosynthesis?Photosynthesis is defined as the process through which green plants use energy from sunlight to transform carbon dioxide and water into food. It is a process that only happens in plants that contain the chlorophyll, a green pigment used in food preparation. Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later.
During photosynthesis, plants take up carbon dioxide (CO2) and water (H2O) from the soil and atmosphere. Plants take in carbon dioxide from the atmosphere as they photosynthesize. Plants can absorb the gas carbon dioxide from the air by way of microscopic holes in their leaves. Once they have carbon dioxide and water, they can use solar energy to create food.
Thus, the atmosphere is the source of the carbon dioxide that is used in photosynthesis. Hence option c is correct.

The_______system is the main transport system of the human body. it is made up of the heart,blood,and blood vessels namely_____________. _______________,And________________.These vessels bring oxygen-rich blood also.Called_____________ to the different tissues in the body and transport_____________from the tissues to the lungs,in a process called circulation
Answers
Answer:
The circulatory system is the main transport system of the human body. it is made up of the heart, blood, and blood vessels namely arteries , veins And capillaries .These vessels bring oxygen-rich blood also Called veins to the different tissues in the body and transport blood from the tissues to the lungs ,in a process called circulation
Explanation:
ABOUT CIRCULATORY SYSTEM -: Blood vessels that carry blood away from and into the heart make up the circulatory system. Blood is carried away from the heart by arteries, and blood is carried back to the heart by veins. Oxygen, nutrients, and hormones are carried to cells by the circulatory system and waste materials, such as carbon dioxide, are extracted.
THREE MAIN BLOOD VESSELS -:
ARTERIES -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. The aorta, the large artery leaving the heart, begins with the arteries. They carry blood rich in oxygen away from the heart to all the tissues of the body. As they carry blood further from the heart, they branch several times, becoming smaller and smaller.VEINS -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. These are vessels of the blood that carry back oxygen-poor blood to the heart. When they get closer to the heart, the veins get bigger and bigger. The superior vena cava is a large vein which carries blood from the head and arms into the heart, and the inferior vena cava carries blood from the abdomen and legs into the heart. CAPILLARIES -: Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow the passage of oxygen, nutrients , carbon dioxide and waste products from and to the tissue cells.BLOOD -: Blood circulates through the entire body through a network of vessels to provide oxygen and nutrients to individual cells and helps to dispose of metabolic waste. The blood around the blood vessels pumps the heart. Blood and circulatory processes circulate oxygen and extract carbon dioxide.
18. Lab Summary - Explain how this experiment models a cell membrane. Use the
following terms in your explanation: selectively permeable, hypertonic, diffusion, indicator.
Answers
Answer:
Cell membrane is considered as boundary of the cell.
Explanation:
Cell membrane is the boundary of the cell which is selectively permeable that allows the micro-nutrients, water and gases like oxygen and carbondioxide etc through the process of diffusion. When the water goes inside due to diffusion it is the indicator that there is less quantity of water present inside the cell as compared to the external environment, this phenomena is called hypertonic.

The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is the largest organ in the body. Your skin and its accompanying structures like hair and mucus are part of the body's first line of defense against pathogens. Describe two ways that the integumentary system protects your body systems from invasion.
Answers
Answer:
Explanation:
Skin is the first line of defense against various harmful activity due to contact with grit, microbes, or harmful chemicals. Sweat produces from sweat glands deters microbes from over colonizing the skin surface by producing dermicidin, which has antibiotic properties prevention infection.
The body has Heat and cold receptors are located in the skin. When the body temperature rises, the hypothalamus in the brain sends a nerve signal to skin glands that produces sweat and they release 1-2 liters of water per hour this cools the body.
The hypothalamus also beings about dilation of the blood vessels of the skin, this allow more blood to flow into those areas with high temperature causing the heat to be convected away from the skin surface.

Explanation:
the vacuole stores water, waste, food, etc. and then releases it from the cell.
Organelles are present inside the cells of eukaryotic organisms. The vacuoles of the cells temporarily store water, wastes, food, and other material. Thus, option D is correct.
What is a vacuole?A vacuole is an organelle present in an animal and plant eukaryotic cell. Though they differ in size and number in both cells but have various functions important for the survival of the cell.
The vacuole of plant cells is large than the animal cell and stores the cellular substances, cell waste, and synthesized food particles. In plants, they maintain the water and osmotic balance.
They regulate the storage and transport of cellular materials, maintain turgor pressure, and control the localization of the proteins synthesized by translation.
Therefore, option D. vacuoles stores waste and food.

Answer: The sequence of nucleotide bases in the DNA
Explanation: The sequence of the nucleotides directly code for each trait. The genetic code is contingent on the sequence of the bases- if the order is changed (you will learn about this in genetic mutation), it would create a different code, which could possibly create a totally different gene depending on which base is changed.

What is DNA?Every living thing has self-replicating genetic material called DNA. It is a repository for all genomic data. It contains instructions that let organisms to develop, grow, survive, and reproduce. It's a big molecule with a genetic "code" in it. The foundation of human development is this genetic code. However, external factors including diet, lifestyle, and the environment influencing human evolution may have an impact.Nucleotide molecules, which make up DNA, are its constituent parts. The carbon-sugar group, phosphate group, and nitrogen base are the three elements that make up a DNA molecule. The four other nitrogen bases are adenine (A), cytosine (C), guanosine (G), and thymine (T).3 billion base pairs make up the distinctive human DNA, which is what makes it unique. But 99.9% of them are universal to humans. What information must be coded in order to support the growth and development of the organism is determined by the order of these bases. During transcription, when DNA is copied, a substance called as RNA is produced (Ribonucleic Acid). It is this RNA's job to convert genetic information from DNA to protein, which is then read by ribosomes.To learn more about DNA, refer to https://brainly.com/question/16099437

Carlos is asked by his teacher to closely observe the pixels on a television screen with a magnifying glass. He is told that each pixel emits one color of light at a time and that the colors emitted by adjacent pixels combine to create an image on the television screen. His teacher asks him to identify which colors the pixels emit. Carlos knows that any shade of paint can be made out of red, blue, and yellow paint. So he decides not to closely observe television and concludes that television pixels must emit red, blue, or yellow light to generate an image.
How did Carlos reach his conclusion?
A. He closely observed the colors of television pixels emitted.
