Remoras are fish that attach themselves to sharks. They travel with the shark and eat leftover shark food. This neither harms nor benefits the shark. What type of symbiotic relationship is this? a) parasitism B) commensalism C) mutualism
Answer:
B) commensalism
Explanation:
The symbiotic relationship between Remoras and sharks is a commensalism relationship where the the shark neither benefit nor loss from such relationship
Commensalism relationship is a relationship in which the one of the living organism benefits from associating with another organism (host organism). The commensal organism benefits such things as locomotion, food, shelter etc.
The host organism neither benefit nor get harmed
From the question, Remoras are the commensal organism while sharks are the host organism

If an organism didn't have DNA, it would be missing which sign of life? A. one or more cells B. information system C. response to the environment D. complex chemical activities
Answer:
The correct answer would be - option B. information system.
Explanation:
DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.
So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.
Which of the following processes is driven by the energy from Earth's interior?
A.) Photosynthesis
B.) Melting of rock
C.) Beach erosion
D. Decomposition
Answer: Decomposition
Explanation: It is
The interior heat energy of the Earth drives processes like melting, crystallization, and deformation that alter the atomic structure of rocks, hence option b is correct.
What is energy from Earth's interior?Rock material to the Earth's surface where it is exposed to surface processes like weathering and erosion.
Only a few factors account for the majority of the energy in the Earth's system: solar energy, gravity, radioactive decay, and the rotation of the Earth.
Many surface processes, including winds, currents, the hydrologic cycle, and the entire climate system, are powered by solar energy.
Therefore, Melting of rock, volcanism, metamorphism, and plate tectonics are examples of internal processes that are driven by energy from within the earth.

What do you think would happen if negative feedback mechanism absent in our body?
Answer:
Negative feedback has the function of controlling and regulating the processes of a system. Without such a mechanism there would be no balance in the body. As such, it is responsible for maintaining balance within the system, counteracting or modifying the consequences of certain actions, that is, it seeks to reduce the effects of external aggressions.
Explanation:
When an internal or external variable of the body changes with respect to normal limits, a response is triggered that reverses the change. In this case, we are in the presence of a negative feedback. In negative feedback there are normally three parties involved: the so-called receptor, the control center, and the so-called effector. The receptor is the organ or tissue that intervenes in the negative feedback process, recording the values of some variable of the organism; these variables can be very different, for example temperature, blood pressure or blood glucose concentration. The information collected by the receiver is continuously sent to the control center. When the received values go out of the normal ranges, the control center will send orders to the effector organs so that they begin to function in a certain way that helps to return the values of the variable to the normal values in basal state.Negative feedback is the main control mechanism of homeostasis and as such is essential to keep the different parameters of the body between the values in which it can perform its functions. If negative feedback didn't exist, we would die. In fact, when negative feedback control mechanisms fail, we have to resort to medicine to help the body maintain homeostasis.
A plant can have yellow (Y) or green (y) leaves. It can also have smooth (S) or rough (s) seeds. A plant has YySs. What possible gametes can the plant produce?
Answer: Possible gametes: YS, Ys, yS, or ys
Explanation: When given the genotype of a dihybrid to cross, you have to account for all possibilities. A way to do this would be to think of it like you’re multiplying or FOIL-ing an equation in math. This means YySs could also be written as: (Yy) x (Ss). Simply multiple the first variable of the first group (Y) by the first and second variable of the second group (S and then s), and then repeat for the second variable of the first group (y).

What are the advantages of interconnecting air sacs for birds?
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"advantages of interconnecting air sacs for birds"
The air sacs permit a unidirectional flow of air through the lungs.Unidirectional flow means that air moving through birds lungs is largely fresh air and has a higher oxygen content.In contrast air flow is bidirectional in mammals moving back and forth into and out of the lungs.As a result air coming into a mammals lung is mixed with old air has less oxygen. so in bird lungs,more oxygen is available to diffuse into the blood(avian respiratory system).
The air sacs are thin membrane structures connected to the primary or secondary bronchi via ostia and they comprise most of the volume of the respiratory system.Air sacs are poorly vascularized by the systemic circulation and do not directly participate in significant gas exchange but act as a bellows to ventilate the lungs.In most species,there are nine air sacs which can be considered in cranial and caudal functional groups.The cranial group consists of the paired cervical air sacs,the unpaired clavicular air sacs and the paired cranial thoracic air sacs.Answer:

what is one negative of aluminum being the best copper waste method?
Answer:
Copper is a 100 percent recyclable material. According to the Copper Development Association, copper's recycling rate is higher than that of any other engineering metal. Every year in the United States, nearly as much copper is recycled as is mined. Excluding wire production, almost 75 percent of U.S. copper used comes from recycled copper scrap. There are so many advantages to recycling copper that the value of scrap is approximately 85 to 95 percent the price of newly mined ore.
