What is the function of muscle tissue?
A. Can you send signals to control the body
B. To Cover the body do you protect other cells
C. Two contracts to cause movement in the body
D. To transport materials and defend the body
Answer:
i think its c
Explanation:
because thats the mane function off muscle tissues and they dont really do any other things
The function of muscle cells is to contract to cause movement in the body. So the correct option is C.
What is muscle tissue?
Muscle tissue is composed of muscle cells. These cells have the unique ability to ability to contract and relax which results in movement of the parts of our body.
The muscle is compact with muscle cells. It is well supplied with blood vessels. These are long and slender and thus they are sometimes also referred to as muscle fibres.
These cells are arranged usually in the form of bundles or layers. They are surrounded by connective tissue. There are two contractile proteins present in the muscle tissue called Actin and myosin.
They are categorized as skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue.
Cylindrical, multinucleated, striated cells which are under voluntary control are called skeletal muscle cells. Spindle-shaped cells with a single, centrally located nucleus and lack striations are smooth muscles. They are involuntary muscles. Cardiac muscles have branching fibres, uninucleated cells with striations, and intercalated disks. It is also involuntary.
Therefore the correct option is C.

The diagram shown represents the fluid mosaic model of a plasma membrane. What do letters X and Y indicate?
a.
X indicates nuclei and Y indicates ribosomes
b.
X indicates pores and Y indicates cellulose
c.
X indicates proteins and Y indicates lipids
d.
X indicates lipids and Y indicates proteins
Answer:
X indicates proteins and Y indicates lipids
The membrane's fluidity and elasticity are provided by the phospholipid bilayer. The cell membrane also contains trace amounts of carbohydrates. Thus, option C is correct.
What is the fluid mosaic model?According to the fluid mosaic theory, the cell membrane is made up of several continually moving components, including phospholipids, cholesterol, and proteins.
This movement aids the cell membrane in preserving its function as a partition separating the interior and exterior cell surroundings.
Changes in membrane fluidity can affect how proteins are expressed, which receptors are visible on cell surfaces, and how cells operate.
The fluidity of the membrane at low temperatures depends on the ratio of saturated to unsaturated fatty acids.
Therefore, X indicates proteins and Y indicates lipids

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.
Answer:
Yes, it is all of the above.
Explanation:
Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

explain explicitly how 3 body systems work together
Answer/Explanation:
Using body systems respiratory, circulatory, and muscle.
The respiratory, circulatory, and muscle work together because the circulatory carries blood to the muscles and respiratory systems. The respiratory systems gives breathe and makes it able to live so the other two can function. The muscle systems helps move using the breath of life and the blood from the circulatory.

How are metations and adaptations are related
Answer:
A mutation that occurs in body cells that are not passed along to subsequent generations is a somatic mutation. ... Alternately, if the mutation has a positive affect on the fitness of the offspring, it is called an adaptation. Thus, all mutations that affect the fitness of future generations are agents of evolution.

You have written wrong spelling its mutation.
organism whose cell does not contain a nucleus
Answer:
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the ________, and the source of infection is the ___________. View Available Hint(s) Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the ________, and the source of infection is the ___________. soil; soil rice; rice rice; soil soil; rice
Answer:
soil; rice
Explanation:
Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the soil, and the source of infection is the rice.
A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.
On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.
