A would have it.

A is hetrozygous person. Since it is dominant, you only need 1 "H" to recieve the gene. Since B has two "h", it would not contain the disease.

What are the similarities and differences between food chains and food webs?
ra1l [238]
A food chain shows a single connected path of energy flow through an ecosystem. It shows the different levels of eating in an ecosystem. Both a good web and a good chain include a number of organisms including both producers and consumers. A food chain is very simple while a food web is complex and consists of a number of food chains. In a food chain each organism has only one consumer or producer.

A group of rabbits lives in an area that normally has mild winters that are not too cold. This
ahrayia [7]

Answer:

A. Extra thick fur

Explanation:

Because the winter is cold and little body fat and a dark colored fur will get it killed faster, but long ears can help the bunny hear the danger but I don't think there will be any predetors out in the harsh snow.

What are the different types of connective tissue? where in the body could each be found?
GrogVix [38]
The different types of the Connective tissue are the Cartilage, Bone Tissue, White Adipose Tissue, Fascia, Fibrocartilage, Hyaline Cartilage, Elastic Cartilage, Costal Cartilage, Brown Adipose Tissue, and Adventitia....


Cartilage- Found in the Joints between bones, the elbow, your knees and ankles, the vertebrae, and on the end of ribs

Bone Tissue- Bone Tissue is found in small blood vessels, epithelium, and the nerves.

White Adipose Tissue- Is located beneath the skin, around internal organs, in bone marrow, and the breast tissue

Fascia-<span>This is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the </span>body<span>. This suspends the organs within their cavities and wraps them in layers of connective tissue membranes.

Fibrocartilage- Found in the public </span>symphysis, the anulus fibrosis of intervertebral discs.

Hyaline Cartilage- Found in the Bronchi, bronchial tubes, costal cartilages, larynx, nose, and the trachea.

Elastic Cartilage- Found in the Epiglottis, and the Pinnae.

Costal Cartilage- Found at the anterior ends of the ribs.

Brown Adipose Tissue- Found in Neonates, brown fat<span> makes up about 5% of the body mass and is </span>located<span> on the back, along the upper half of the spine and toward the shoulders.

Adventitia- Is found in the Connective System and in the nerves.....


I hope this helps with this question you asked!!! It states the different types of the connective tissue and where they can be found!!!! Have a great </span>day!!!

Explanation:

-Q. <em>How do membrane proteins aid in the movement of hydrophilic substances across the membrane?</em>

Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane from the extracellular or intracellular space.

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Similarly via osmosis, molecules of water pass through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Transport proteins are transmembrane proteins involed in moving molecules across the membrane.

There are two types:

  1. Channels or pores are filled with water, enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration down the concentration gradient -this is a passive part of facilitated diffusion. Channels may undergo minor changes to become open or closed whereas pores are always in open states <em>e.g. H2O movement into and out of the cell via aquaporins.</em>
  2. Carrier proteins bind specifically bind to molecules and move them across or against concentration gradients. Unlike facilitated diffusion, carrier proteins directly or indirectly use energy in the form of  ATP and modify solute specific regions, that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane- this is called <em>active transport.</em> <em>e.g. Na+/K+transported by the enzyme ATPase </em>

How are photosynthesis and cellular respiration linked
RoseWind [281]

Photosynthesis is when a plant converts sunlight into energy, and cellular respiration is when cells convert food into energy.
