The organization of skeletal muscle at tissue level is made up of:

• Epimysium; around the muscle belly.

• Perimysium; surrounding the muscle fascicles.

• Endomisium; coating the muscle fibers, which in turn, are made up of myofibrillar structures.

The muscle cell or fiber is the structural and functional unit of muscle tissue. The skeletal muscle tissue has a striated appearance.

Muscle fibers are organized in bundles surrounded by an outer connective tissue membrane, called the epimysium.

Very thin septa of connective tissue start from this, which are directed towards the interior of the muscle, dividing it into fascicles, these septa are called perimysium.

Each muscle fiber is surrounded by a very thin layer of reticular fibers, forming the endominsium.

The connective tissue holds the muscle fibers together, allowing the contraction force generated by each individual fiber to act on the entire muscle, thus contributing to its contraction.

Therefore, we can conclude that the organization of skeletal muscle at tissue level of the striated muscle fibers is given by the connective tissue that is organized in: Endomysium, Perimysium and Epimysium.

Answer:

When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.

Explanation:

During photosynthesis, light absorbed by plant is used for energizing electrons  for an electron transport chain to take place in thylakoid membrane.

Photosynthesis is defined as the  process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in the form of  molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the percent  of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and have a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles which are called chloroplasts while in bacteria they are present in plasma membrane.

If I put a potato in ammonia (a base) then the activity of catalase will decrease  because the pH level will be to basic for any catalytic (catalase) activity.

Hope this helps! Please correct me if I'm wrong :)

If I put a potato in ammonia (a base) then the activity of catalase will decrease  because the pH level will be to basic for any catalytic (catalase) activity.

An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.

Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.

Therefore, If I put a potato in ammonia (a base) then the activity of catalase will decrease  because the pH level will be to basic for any catalytic (catalase) activity.

Answer:

Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time.

Encyclopaedia Britannica's editors oversee subject areas in which they have ... from intrusive rocks on the basis of their texture and mineral composition

Explanation:

The presence of a layer of extrusive rocks is due to a single volcanic eruption and its presence in the middle of a rock formation may be because these rocks are younger than the surrounding rock formations.

The presence of a layer of extrusive rocks in the middle of a rock formation refers to the geological history of the area. These rocks are formed from lava that has been erupted from a volcano and cooled quickly on the Earth's surface followed by the cooling at the surface of the Earth. This suggests that a volcanic event has occurred in the area.

When a volcanic eruption occurs, lava is ejected from the volcano and flows onto the Earth's surface followed by its solidification into extrusive rocks which have fine-grained texture.

The presence of extrusive rocks in the middle of a rock formation may be due to a single volcanic eruption or these rocks are often younger than the surrounding rock formations.

Therefore, the presence of extrusive rocks is due to a single volcanic eruption and may be younger than the surrounding rock formations.

Answer:

-temperature and rainfall

Explanation:

Terrestrial biomes are defined as regions of similar vegetation and climates. Certain types of vegetation have specific growth requirements for their optimal water and temperature. They tend to thrive within regions where these needs are met, thus making up the dominant plant types.

At or close to the equator, biomes are warmer due to the high intensity of sunlight (the equatorial regions the most sunlight), and warmer air holds more moisture, making the regions more prone to rainfall.

The correct answer is E.

Explanation:

Lipids are a heterogeneous group of organic compounds divided into fats or oils, phospholipids and cholesterol esters. The lymphatic vessels are responsible for the transport of lipids and fat-soluble vitamins (A, D, E and K), which are absorbed through the digestive tract, that is, they act as capturers of fats and excess fluids from the human body, always present in the blood vessels. They do not carry blood, but lymph, a clear liquid. They play an important role in the transport of fats, in the recovery of fluids that escape from the blood capillaries and in the fight against infections. In the small intestine, specialized lymphatic capillaries transport lipids from the diet to the lymphatic vessels and, ultimately, to the blood. The presence of these lipids makes the lymph drained through the small intestine appear creamy white.

Explanation:

edge 2020

i'm just different

During the reduction stage of the Calvin cycle, the 3-PGA molecules produced by carbon fixation are transformed into simple sugar molecules – glucose.

In this step, the energy is supplied by the ATP and the NADPH produced during the light-dependent photosynthesis reactions.

ATP, or NADPH, is used to transform the 3-PGA molecules into three-carbon sugar molecules (G3P molecules). The name “G3P” comes from the fact that NADPH gives electrons to, or breaks down, a 3-carbon intermediate to form G3P.

Carbon dioxide in the atmosphere undergoes a redox reaction to glucose. This redox reaction requires the total reduction of CO2 using the electrons available in the oxidation of the NADPH. Thus, the dark reactions are a redox pathway. Calvin-Benson cycle.
