Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system
Answer:
True.
Explanation:
It is TRUE that Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system.
This is evident in the fact that Polyculture is a type of agriculture whereby more than one species of plant is cultivated or animals reared simultaneously.
For example, Polyculture in animals may involved paddlefish, tilapia, and bighead carp reared in the same pond. In this case, the paddlefish will feed on crustaceans, while tilapia feed on zooplankton and phytoplankton. Also, bighead carp will feed on zooplankton and big phytoplankton.
what gives sperms motility
Answer:
The tail of the sperm, the flagellum
Explanation:
We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.
Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.
Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

The shadow zone exists due to the of seismic waves.
O A. reflection
O B. refraction
O C. absorption
OD. deletion
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.

The sonographic appearance of choledocholithiasis is best described as. Nonshadowing mobile hyperechoic mass. Mobile hyperechoic focus demonstrating posterior shadowing. Immobile echogenic focus demonstrating a posterior shadow. Mobile hyperechoic focus demonstrating anterior shadowing.
Answer:
Mobile, hyperechoic focus demonstrating posterior shadowing
Explanation:
Cholecystitis can also be regarded as gallbladder inflammation i.e inflammation of a digestive organ which is a small organ beneath the liver. The causes of Cholecystitis is as a result of blocking of tube( cystic duct) that leads the gallbladder all the way to the small intestine, as a result of this Bile can builds up then inflammation will occur.

Senescence __________. Question 5 options: a) begins at the moment of conception and accelerates after age 40 b) occurs across all parts of the body at the same time and speed c) begins once body structures reach maximum capacity and efficiency d) occurs because the physical body wears out from use
Answer: c. Senescence begins once body structures reach maximum capacity and efficiency
Explanation: Senescence is simply ‘growing old’. Aging sets in at the time when physical development is complete - when a person reaches their ‘prime’. After that a person is ‘past their prime’ which is the subjective recognition of the on set of gradual deterioration. The biological rationale is that the purpose of life is to survive to reproductive age and to reproduce, and in some species to assist progeny to survive to reproductive age. Beyond that, survival has limited value.
An analogy is the length of an elephant’s trunk. It is as long as it needs to be, determined by natural selection, but no longer than it needs to be for optimum efficiency, again determined by natural selection.

An apple farmer notices that two of his trees produce particularly sweet apples. The farmer thinks that these sweeter apples would sell very well andcould make him a lot of money. He uses a Q-tip to pollinate the flowers of the sweet apple tree with pollen from the other sweet apple tree's flowers. He then takes the seeds from the fruit that they produce and grows a new field of trees from them. Almost all of these new trees make very sweet apples like the first two trees did.
Answer:
It is a right method for making a variety.
Explanation:
This is the right method for making sweet apples variety because in apple, cross pollination occurs and for making a new variety self pollination is the best way to prevent impurities in making a new variety. Due to self pollination, the farmer gain the sweet apple variety which help them to make more money by selling these sweet apple because of its demand.
