Pistil- The female reproductive structure of flowers. Filament- A thin stalk of the stamen. anther- The part of the stamen that contains pollen. Pollen- A fine dust that contains the speed of seed - producing plants. Stigma- The tip of the pistol. Style- The narrow elongated part of the pistil between the ovary and the stigma. Ovary- The rounded base of a pistil that contains one or more ovules. Ovule- A small body that contains the female germ cell of a plant. Stem- A slender or elongated structure that supports a plant or fungus or a plant part or plant organ.

Which of the following is a type of lipid or composed of lipids?
mamaluj [8]

The answers are all accurate. Lipids, or substances consisting of lipids, include triglycerides, plasma membranes, cholesterol, and oils.

Lipids are substances that contain lipids, such as glycerides, plasma membranes, cholesterol, and oils.

Glycerol is esterified into three fatty acid chains with distinct lengths and contents to form lipid molecules known as triglycerides. Saturated or unsaturated fatty acid chains are the two types.

The phospholipid bilayers that makeup plasma membranes are lipids. Glycerol, a head with a phosphate connection, and two fatty acid tails make up a phospholipid. Hydrophobic interiors and hydrophilic exteriors characterize phospholipids.

In the blood, a lipid called cholesterol is carried by proteins called lipoproteins throughout the body.

Liquid lipids exist in the form of oils. Lipids share a similar chemical composition. They contain glycerol esters attached to fatty acids in the form of long-chain molecules.

As a result, we can conclude that every response is correct. Triglycerides, cholesterol, plasma membranes, and oils are lipids or lipid-containing compounds.

When are lung transplants performed? What are the risks of lung transplants?
ryzh [129]

In most cases, a lung transplant is done only after all other treatments for lung failure are unsuccessful. Lung transplants may be recommended for people under age 65 who have severe lung diseases. The major risk of a lung transplant is organ rejection. This happens when your immune system attacks your donor lung as if it were a disease. Severe rejection could lead to failure of the donated lung. Other serious complications can arise from the drugs used to prevent rejection.

Match each of the four barriers of innate immunity with its mode of action.
serg [7]

The matches are

A. anatomical barrier   is matched with 1. secretion of sweat, saliva,  and tears.

The epithelium is a physical barrier constituting one of the first defenses against infectious agents. The desquamation of the epidermis thus eliminates bacteria or other infectious agents that have adhered to the surface of the epithelium. In the digestive tract and the respiratory tract, the movement operated by the peristalsis or the eyelashes contribute to the elimination of the infectious agents. The intestinal flora prevents colonization by pathogenic bacteria acting in particular by competition for nutrients. Tears and saliva also help prevent infection of the eyes and mouth, respectively.


B. physiological barrier   is matched with 4. changes in pH and  temperature.

In addition to this physical (or anatomical) barrier, the acidic pH and low moisture content of the stratum corneum, and the skin temperature below 37 ° C, are detrimental to bacterial growth. Finally, the presence of antimicrobial peptides and lipids make the epidermis a true defender against infection.


C. phagocytic barrier  is matched with 3. signaling to macrophages.

Macrophages are cells belonging to white blood cells (leucocytes), which infiltrate tissues. They come from the differentiation of circulating blood leukocytes, monocytes. Monocytes and macrophages are phagocytes and are therefore capable of phagocytosis.

They participate in innate immunity as a non-specific defense, but are able to participate in adaptive immunity via opsonization.


D. inflammatory barrier  is matched with 2. secretion of chemicals.

In an inflammatory reaction, blood flow increases at the lesion area. The blood vessels become more permeable thanks to vasodilator chemical substances, which allows the migration of cells from the blood to the tissues (the call is made using chemokines). The first cells arriving at the site of inflammation are often neutrophils, then macrophages arrive and then lymphocytes if there is immune stimulation.

This is hard. pls help. Write an equation for cellular respiration. Write an equation for photosynthesis. How are these two equa
ad-work [718]

Answer:

equation for cellular respiration: C6H12O6 + 6O2 + 6H2O → 12H2O + 6CO2

equation for photosynthesis:: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Plants make their own food by photosynthesis. During photosynthesis a plant takes in water, carbon dioxide and light energy, and gives out glucose and oxygen.
