Answer:
a. Endomysium 8. The layer of connective tissue that surrounds an individual muscle fiber
b. Epimysium 6. The layer of connective tissue that surrounds a skeletal muscle
c. Fascia 3. Connective tissue located between adjacent muscles
d. Fascicle 12. A small bundle of muscle fibers within a muscle
e. Myosin 11. Protein found within a thick filament
f. Perimysium 4. The layer of connective tissue that separates a muscle into small bundles
g. Sarcolemma 5. The plasma membrane of a muscle fiber
h. Sarcomere 7. Unit of alternating light and dark striations between discs (lines)
i. Sarcoplasm 2. The cytoplasm of a muscle fiber
j. Sarcoplasmic reticulum 9. A cellular organelle in muscle fiber corresponding to the endoplasmic
k. Tendon 10. The cordlike part that attaches a muscle to a bone
l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane
Explanation:
A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.
The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

Why do you think that the shape of the different types of fatty acid molecules affects how easily they solidify?
Answer:
Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses.
Lipid molecules consist mainly of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Both types consist mainly of simple chains of carbon atoms bonded to one another and to hydrogen atoms. The two types of fatty acids differ in how many hydrogen atoms they contain.
Explanation:
Can I plz have brainliest
The shape of the types of fatty acid molecules has an impact on their solidification.
It should be noted that in the unsaturated fatty acid, there is at least a double bond in its string. The carbon atoms that are joined by the bonds lead to the change in their shapes.
While saturated fatty acids have a linear structure, the unsaturated fatty acids kink or bend in order to form double bonds within the chemical foundation.

An experiment was done by Gierer and Schramm where they exposed plant tissue to purified RNA from tobacco mosaic virus, and the plants developed the same types of lesions as if they had been exposed to the virus itself. After checking relevant websites, what would you suggest would their results be if the RNA is treated with DNase, RNase, or protease prior to its exposure to the plant tissue
Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus, if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.
A protease is an enzyme that degrades the structure of proteins. Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus.

If the amount of glucose is increased for an animal so what will happen
Answer:
In normal course, excess glucose gets stored in the liver as glycogen and if the levels are more it gets converted into fat and gets stored in liver as well as in adipose tissues. A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy.
Explanation:
The growth patterns of plants such as ivy and pole beans are regulated by
A.) phototropism
B.)thigmotropism
C.)all of the above
Answer:
The correct answer is - C) all of the above.
Explanation:
The growth patterns of the plants such as ivy and pole beans depend and controlled by various physiological processes. These physiological process helps in the plants to grow in a particular direction so they can get nutrition and resources they require for their growth and development.
These processes are Gravitropism, phototropism, and thigmotropism. Gravitropism ensures that plant roots grow towards the soil so they can get water and other nutrients. Phototropism is the other process that allows the plant to move in the direction of the light so they can get enough light for the photosynthesis process. Thigmotropism is the process or defense mechanism that and movement by touch stimulus.
how to read a scientific paper? and use a publication to demonstrate the different steps? pleas help me
Answer:
Attempting to read a scientific article for the first time may seem overwhelming and confusing. This guide details how to read a scientific article step-by-step. First, you should not approach a scientific article like a textbook— reading from beginning to end of the chapter or book without pause for reflection or criticism. Reading and understanding research papers is a skill that every single doctor and scientist has had to learn during graduate school. You can learn it too, but like any skill it takes patience and practice. Reading a scientific paper is a completely different process from reading an article about science in a blog or newspaper.

Mary received a flu vaccine. Why didn't the vaccine make her sick?
Mary didn't get sick from the flu vaccine because it contains the smaller portion of the flu which isn't strong enough to infect you. Moreover, your white blood cells attack the portion of the flu while the memory cells take note of the flu, so when it comes next time, it won't affect your body because it knows how to fight the virus.
Hope this helps!
