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.

Increased motion in the particles in a liquid allows the particles to ____
stop their flow
hold their shape
slip past one another
Slip past one another. Therefore, option (C) is correct.
What is motion in particles?Motion in particles refers to the movement or activity of the individual components, such as atoms or molecules, within a substance. In a liquid, the particles are not held in a fixed position as they are in a solid, but instead are able to move around and slide past one another.
This allows liquids to flow and take the shape of their container. The amount of motion in the particles can be affected by factors such as temperature, pressure, and the presence of other substances.

Answer:
They are not using as much or any pesticides, which is used to get rid of bugs that eat their crops, yet harms humans at the same time. Another way to make sure the soil stays healthy it to keep growing plants and crops. Usually when soil is left idol for too long, it will become dry and useless.
Explanation:
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).

In a recent murder mystery, a woman died in minutes after consuming cyanide-laced sugar (glucose). Forensic scientists did some research and found that death was caused by lack of the energy rich molecule called ATP (substance that is created after glucose is broken down, and energy is released). Which cellular organelle was affected by this poison?What cellular process should it have been performing
Answer:
Mitochondria was affected by the poison cellular respiration Hope it helps youThe woman died minutes after consuming the cyanide-laced sugar because complex Iv in the electron transport chain failed to function. This process takes place in the mitochondria. As a result, lack of energy leads to death.
How does the ATP form in the mitochondria?
The cell does glycolysis and produces pyruvic acid. This pyruvate enters the Krebs cycle and electron transport chain to form ATP. This takes place in the presence of oxygen.
The electron transport chain (ETC) takes place in the inner mitochondrial membrane. The electron moves across the different complexes. The electron is finally accepted by oxygen. The majority of the ATP is formed during this process. When cyanide is taken, it acts as an inhibitor of complex IV of the ETC. Hence, the electron can't flow and ATP can't form. Due to this, the woman died of lack of energy.
Hence, cyanide uptake stops the complex IV of ETC, and as a result, ATP is not formed.

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

Which of the following statements is true?
Most evaporation happens at the earth's poles.
The total amount of water on the earth stays the same.
Water enters the atmosphere through condensation.
New water is created by the water cycle.
Answer:
water enters the atmosphere by condensation, the heat evaporates the water in turn increases the humidity of the earth.
Answer:
The total amount of water on the earth stays the same.
Explanation:
The water never leaves the Earth’s atmosphere, and there is no water coming into the Earth from space, so water always exists in the same amount. The reason water can’t leave the Earth’s atmosphere is good old gravity. For a significant amount of water vapor to escape our planet, it would need to be moving with the velocity of a rocket ship.

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.

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:

Think about how DNA replication is similar and different in prokaryotes and eukaryotes. Place X's in the table to show if the description applies to one type of organism or both.
Answer:
I believe this is correct.
Explanation:
DNA replication is a process in which a copy of DNA is produce through original DNA.
Replication is happened in both prokaryotes and eukaryotes.
What is DNA replication?Replication is a biological process in which a replicate of original DNA is produced.
In prokaryotes:
In prokaryotic cells, the cell division occurs in one single origin. It is bidirectional and carry out in three steps: initiation, elongation, and termination.
Three enzymes work here: polymerase I, II, and III.
In eukaryotes:
In eukaryotes, the DNA replication occur within the cell division. It happens in S phase. It also completes into three steps: initiation, elongation, and termination.
Furthermore, it controls by the cell cycle check point.
Thus, DNA replication is an important process in which copy of DNA is made.
