Eukaryotic cells have a more sophisticated structure than prokaryotic cells, as should be obvious. Organelles enable multiple processes to take place simultaneously in the cell. Let's first examine the plasma membrane and the cytoplasm of the eukaryotic cell before talking about the functions of the organelles within the cell.
Eukaryotic cells, like prokaryotes, have a plasma membrane that is composed of a phospholipid bilayer with embedded proteins and serves to separate the inside of the cell from the external environment. A phospholipid is a lipid molecule made up of a phosphate group, a glycerol backbone, and two fatty acid chains. In order to maintain internal conditions, the plasma membrane actively brings in or expels other substances while actively regulating the passage of others, such as organic molecules, ions, and water. Passively, other substances move across the membrane.

If two erminate chickens were crossed what is the probable In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette
If two erminette chickens are crossed, the genotypes of the offspring will be 1/4 BB, 1/2 BW, and 1/4 WW. The phenotypes of the offspring will be 1/4 black, 1/2 erminette, and 1/4 white.
What is an Erminette chicken?
Erminette chickens are a rare breed of chicken originating in France. They are a dual-purpose breed, meaning they are used for both egg production and meat production. They are a small breed, with hens only growing to about 2.5 pounds and roosters about 3.5 pounds. They have a white face, with a white triangle at the top, and a black body. They are also known for their large, bright red combs.
If two erminette chickens are crossed, the resulting offspring will be a 1:2:1 ratio of black, erminette, and white chickens. This means that for every two erminette chickens, there will be one black chicken and one white chicken. This is because erminette chickens are heterozygous, meaning they possess both the B (black) and W (white) alleles. When these chickens are crossed, the B and W alleles are each passed on to one of the offspring, resulting in a 1:2:1 ratio of black, erminette, and white chickens.

Which of the following mutation types may change codons downstream of the mutation? Select all that apply.
The right answer is frameshift mutations which change the codons downstream of the mutation. The reading frame may change as a result of a mutation, such as an insertion or deletion of a nucleotide and the arrangement of amino acids is completely altered.
The addition or deletion of nucleotide bases in amounts that are not multiples of three causes a frameshift mutation in a gene. This is important because proteins are written in units of three nucleotides that cells can read. One of the 20 unique amino acids that are utilized to produce a protein is represented by each of these "triplet codons." The entire gene sequence after the mutation will be misread because there is change in regular reading frame. The protein may thus receive the incorrect amino acids or it may gain a codon that prevents it from becoming longer.

What is the primary function of stems?; How does auxin produce Phototropism?; How mitosis occurs in growth of seedlings?; Is the process by which internal environments of an organism are regulated?
Stem supports branches, leaves, flowers, and fruits. It transports water and minerals from the roots to the leaves and other parts of plants. It transports food from leaves to different parts of the plant. It holds the plant upright.Auxin has a role in phototropism, responding to light.
Auxin has a role in phototropism, responding to light. Auxin is produced by cells in the apical meristem. The direction of light is detected at the tip of the shoot by pigments called phototropins. Phototropins stimulated by the absorption of light regulate the transport of auxin. When a shoot is exposed to light from above, auxin efflux pumps are located at the base of the cells in the shoot apex.
Auxin is transported downwards from the meristem, and has an equal distribution in the cells below the meristem. The cells elongate and the shoot grows straight upwards, symmetric growth. When the shoot is exposed to light from one side, this causes auxin efflux pumps to change location inside the cell. They move to the side of the cell furthest away from the light. This causes auxin to be transported to the shady part of the root, generating a higher concentration of auxin on the shady side than on the side exposed to light. This causes more cells on the shady side to elongate and the shoot bends towards the light, asymmetric growth.

which of the following parameters is the most important in controlling cardiac output in healthy people?The factors affecting venous return are normally the most important in controlling cardiac output in healthy people.
The normal ranges of these indexed blood flow measurements for SI and CI are 35-65 mL/beat/m2 and 2.5-4 L/(min m2, respectively. Principal Influences on Cardiac Output: Cardiac output is influenced by the two variables that can change: heart rate and stroke volume.
The amount of blood pumped by the heart's two ventricles per unit of time is known as the volumetric flow rate of the heart's pumping output, or Cardiac Output (CO), sometimes referred to as heart output and frequently denoted by the symbols "Q" or "d Q," or "d Q" C. (usually measured per minute). Cardiac output (CO) is multiplied by the sum of the heart rate (HR), or the number of beats per minute. How successfully the heart can provide for the body's needs depends in large part on cardiac output. The continuous delivery of oxygen to the tissues requires the extended transfer of oxygen to body tissues by systemic circulation of oxygenated blood from the left ventricle of the heart via the aorta and arteries at an acceptable pressure. Oxygen delivery (DO2 mL/min) is calculated as the cardiac output CO times the blood oxygen content of the blood.

Trachea
Respiratory Zone Structures:
Respiratory bronchioles
Alveolar ducts
Alveoli
Conducting Zone Structures: pharynx, nasal cavity, larynx, trachea, terminal bronchioles
Respiratory Zone Structures: alveolar ducts, alveoli, respiratory bronchioles.
Pharynx:-The pharynx, usually called the throat, is part of the respiratory system and digestive system. It carries air, food and fluid down from the nose and mouth. The pharynx is the site of common illnesses, including sore throat and tonsillitis.
Nasal cavity -The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.
larynx -The larynx is a cartilaginous segment of the respiratory tract located in the anterior aspect of the neck. The primary function of the larynx in humans and other vertebrates is to protect the lower respiratory tract from aspirating food into the trachea while breathing.
Trachea- trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs. When you inhale, air travels from your nose, through your larynx, and down your windpipe.
Terminal bronchioles-Terminal bronchioles branch from the lobular bronchioles and connect them to the respiratory bronchioles. The terminal bronchioles branch to ensure that air is distributed to all parts of the lungs and can be used by the alveoli for gas exchange.
Alveolar ducts-Alveolar ducts are tiny ducts that connect the respiratory bronchioles to alveolar sacs, each of which contains a collection of alveoli (small mucus-lined pouches made of flattened epithelial cells). They are tiny end ducts of the branching airways that fill the lungs.
Alveoli -Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
Respiratory bronchioles -Respiratory bronchioles are the final division of the bronchioles within the lung. They are a continuation of the terminal bronchioles and are approximately 0.5mm in size 1. They are comprised of simple cuboidal epithelium and contain a thin layer of smooth muscle and elastic fibers.
