where do land plants get the water that they use in photosynesis
Answers
Answer:
Land plants get the water they use in photosynthesis from the soil through their roots.
Land plants obtain water for photosynthesis from the soil, which is absorbed through their roots and transported to the leaves through the xylem.
Land plants obtain water for photosynthesis primarily from the soil. The process involves a series of steps that enable water uptake and transportation within the plant. First, plant roots, equipped with root hairs, extend into the soil and absorb water through osmosis. This occurs because the concentration of dissolved substances, such as minerals, in the root cells is higher than that in the surrounding soil.
Water moves from the roots to the xylem, which is a specialized tissue responsible for transporting water and nutrients throughout the plant. This upward movement is facilitated by a combination of root pressure, capillary action, and most importantly, transpiration. Transpiration is the loss of water vapor from the plant's leaves through small openings called stomata. As water evaporates from the leaf surfaces, it creates a negative pressure gradient that pulls water up through the xylem from the roots.
Once water reaches the leaves, it is utilized during photosynthesis. The water molecules are split during the light-dependent reactions, releasing oxygen as a byproduct and providing electrons for the production of ATP and NADPH, which are essential for the light-independent reactions (Calvin cycle).
In summary, land plants rely on their roots to absorb water from the soil, which is subsequently transported through the xylem to the leaves where it is utilized in the process of photosynthesis.

What is an atom?An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.
As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Answers
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.

Describe how the components of a meal containing fried fish and toast bread will be processed as they move through the digestive system of man
Answers
Answer:
Explanation:
When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:
1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.
2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.
3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.
4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.
5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.
6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.
Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria
Answers
The reason for the clear zone may be that there is Insufficient lipolytic activity.
Why the clear zone?The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.
Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media. There wouldn't be any observable clearing or lipid hydrolysis zones as a result.

Oxygen evolution, but not photophosphorylation, can be restored by addition of an external electron acceptor, or Hill reagent. How does DCMU act as a weed killer
Answers
Answer:
It acts as a weed killer by blocking photosynthesis
Explanation:
Photosynthesis is important to plants because it is their principal form of energy.
When DCMU is introduced to weeds, what it does is to block or slow down the process of photosynthesis. Carbon dioxide fixation is slowed down causing weeds to die off. DCMU strongly slows down photosystem II. When this is done, lipid and protein membranes would get destroyed and the weed cells would begin to dry and shed off
What was the climate like prior to the extinction ?
Answers
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

Evan finds a rock. He scrapes it with his fingernail and leaves a scratch. His rock must be:
O a metamorphic rock
harder than feldspar
softer than diamond
made of more than one mineral
HELLP
Answers
The correct answer is C. Softer than diamond
Explanation:
Evan observation is related to the rock's hardness, which is usually measured on a scale from 1 to 10, in which 10 represents the hardest rock (diamond). In the case of the rock Evan found, the fact the rock can be scratched just using a fingernail shows the hardness of this rock is 2.5 or below because only minerals with this hardness can be scratched using the fingernail, while a higher hardness requires more complex tools.
Moreover, in this level of hardness, there are minerals such as gypsum or talc and these are softer than others such as feldspar with a hardness of 6 or diamond with a hardness of 10. In this context, it is safe to conclude this rock is softer than diamond. Also, hardness is not enough to determine if a rock contains two or more minerals or if it is metamorphic.

Answers
The one that causes low vascular resistance is high blood pressure. The correct option is 1.
What is vascular resistance?Vascular resistance is used to keep organs perfused. A hyper-adrenergic response occurs in certain disease states, such as congestive heart failure, causing an increase in peripheral vascular resistance.
Obesity can increase vascular resistance due to fat deposition within the blood vessel walls. Dehydration can also increase vascular resistance due to decreased blood volume and viscosity.
High blood pressure, on the other hand, has been linked to decreased vascular resistance. This is because increased pressure can cause blood vessel dilation, which reduces friction between blood and vessel walls.
