Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
Answer: The arteries (the aorta)
Enzyme-containing laundry detergents will remove stains more effectively than detergents without enzymes. Stains will be removed more successfully from clothing with homemade laundry detergent than from commercial detergents.
A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable. A person's age won't alter as a result of other circumstances like what they eat, how much they attend school, or how much television they watch. In actuality, when attempting to establish a link between two variables, you are attempting to determine whether the independent variable affects the dependent variables in any way.
A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend. A test score, for instance, maybe a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.

Answer:
periosteum ----> dense irregular connective tissue
Explanation:
- The periosteum is a dense fibrous membrane that covers the surfaces of bones.
The periosteum consists of two layers-
1. Outer fibrous layer
2. Inner cellular layer
- It is mainly composed of dense irregular connective tissue along with a layer of simple squamous epithelium.
- The function of periosteum is to cover the surface of all the bones except those surfaces that are covered with cartilage such as joints and tendons and ligaments.
A hypothesis is considered scientific if it has something that can be supported or refuted through carefully crafted experimentation or observation
