Answer:
mitochondria
Explanation:
In cells where there is a high energy demand large numbers of mitochondria are found. The tail of a sperm contains many mitochondria and they run in a spiral like form along the length of the tail. In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.

What kind of joint is pictured in the diagram shown? Need Answer ASAP
Answer:
b A moveable moveable joint joint that that allows allows back back and and forth forth movementmovement
Explanation:
A moveable joint that allows back and forth movement. Therefore, the correct option is B.
What is moveable joint?A synovial joint, commonly referred to as a movable joint, allows for a variety of motion between bones. Limbs and other areas of the body that require movement have movable joints.
These joints have a synovial membrane that secretes synovial fluid, and they are enclosed in a capsule of connective tissue. This fluid helps lubricate the joint and lower friction as the bones move in closer proximity to each other.
Ball-and-socket joints, pivot joints, saddle joints and gliding joints are some examples of movable joints. Different types and ranges of motion are possible with each type of joint.
Therefore, the correct option is B.

What type of bond are the arrows pointing to below in the picture
In the outer layer of the sun, energy is transported outward by the rising of hot plasma and sinking of cooler plasma. This transfer is known as
Answer: Convection.
Explanation:
We have 3 types of heat transmission.
Radiation: Heat is transported as electromagnetic waves, this is not the case shown here.
Conduction: When we have two objects with different temperatures and we put them in contact, the system will want to go to equilibrium (both objects have the same temperature) so the hot object will give heat to the cooler object. We usually see this with solid objects.
Convection: It is the heat transfer due to the bulk movement of the molecules, so this need a material medium (it can not take place in solids, because the position of the molecules is fixed in the solids).
Then the rising of hot plasma and sinking of cooler plasma is convection.

which statement best describes the forces in the picture?
a. The applied force in the force of friction are balanced.
b. all four forces are the same size.
c. all four forces are acting in the same direction.
d. The applied force in the force of friction are unbalanced.
Answer: Its A.
Explanation:
None
The applied force and the force of friction are balanced in the picture because of which the person is standing still. Therefore option (A) is correct.
What is force?A change in the force that is applied to an item with mass will cause that thing to move at a different speed. A body's state of rest or motion can be altered by the application of an external agent known as force. It is significant in both magnitude and direction.
The term "frictional force" refers to the force that is produced when two surfaces come into contact with one another and then slide against one another. A few factors that affect the force of friction are as follows: These forces are primarily influenced by the surface texture as well as the amount of force that is drawing them closer together.

B. Stand on a table while swinging the yo-yo.
C. Sit on the ground while swinging the yo-yo.

D. Swing the yo-yo at a lower speed,
SUBMIT
Answer:
it's B
Explanation:
A girl can increase the total energy of this system by standing on a table while swinging the yo-yo. Thus, the correct option is B.
What is Yo-yo?Yo-yo may be defined as a type of toy that consists of a pair of joined discs with a deep furrow between them in which thread is attached and wound.
By reversing the direction of the swing, swinging the yo-yo at a lower speed, and sitting on the ground while swinging the yo-yo decrease the total energy of the system. This is because the system does not have the momentum that is required to increase its overall energy.
Therefore, a girl can increase the total energy of this system by standing on a table while swinging the yo-yo. Thus, the correct option is B.

Answer:
New algorithms for estimating chlorophyll-a in the Spanish waters of the Western Mediterranean Sea from multiplatform imagery This manuscript proposes a set of multi-sensor chlorophyll-a empirical algorithms for improving current estimates of chlorophyll-a concentration in two distinct regions in the Mediterranean Sea.
Many studies in the area of cancer research are opening up new possibilities for cures and prevention measures. One area of research is directed at the effects that chlorophyll may have on cancer cells within the human body. Research is being conducted to investigate whether chlorophyll has important cancer fighting factors that may play a role in the destruction of cancer cells or whether it is an effective preventive agent.
Daily supplements of the chlorophyll derivative, chlorophyllin (CHL) can provide a way to prevent cancer by reducing DNA damage (Arbogast, 1995). The chlorophyllin copper complex (CHL) is a water-soluble version of chlorophyll and is a semi-synthetic prepared substance. CHL is the most common chlorophyll derivative used for cancer related studies (Chernomorsky, 1999). Most research was done using chlorophyllin because chlorophyll is chemically modified to chlorophyllin in the body during digestion. Chlorophyllin given in amounts to that of chlorophyll were equally effective in the studies (Sarkar, 1994). CHL can be added to the diet very easily and may be safe and useful for effective prevention of cancer (Arbogast, 1995).

Answer:
each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana.

What problems can pseudoscience cause for society?
Answer:
It is quite difficult to picture a pseudoscientist—really picture him or her over the course of a day, a year, or a whole career. What kind or research does he or she actually do, what differentiates him or her from a carpenter, or a historian, or a working scientist? In short, what do such people think they are up to?
… it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
The answer might surprise you. When they find time after the obligation of supporting themselves, they read papers in specific areas, propose theories, gather data, write articles, and, maybe, publish them. What they imagine they are doing is, in a word, “science”. They might be wrong about that—many of us hold incorrect judgments about the true nature of our activities—but surely it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
