True or false: All herbivores are autotrophs.
Answer:
false
Explanation:
Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.
how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.
Answer:
No cells are produced.
Explanation:
If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.

Are bacteria and viruses bound by a cell membrane or is it exclusive to one of them? Do bacteria and viruses have a nucleus or do only one of them have one?
Answer:
Explanation:Lack membrane-bound organelles - While bacteria have a few organelles involves in metabolism and reproduction, they, like viruses, do not have membrane-bound organelles. In viruses, the nucleic acid is not contained in a nucleus as is the case with eukaryotic cells.

A train travels 67 km, north along a straight track in 39 minutes. What is the train's average
velocity in kilometers per minutes?
A. 28Km/mins
B. 1.72Km/mins
C. 0.582Km/mins
D. 106 Km/mins
Answer:
B. 1.72Km/mins
Explanation:
The topic is Mathematics, not Biology but okay!
All you have to do is 67/39 which equals 1.72km/mins.
This is because you have to work out the average speed in kilometres per minute. 39/39 = 1 minute

Benny uses a compass to navigate his way through the woods when he
is carnping. The needle on the compass reacts to Earth's magnetic field
by always pointing north. Which part of Earth is responsible for creating
its magnetic field?
A. Cilist
B. inner core
C. mantle
D. outer core
Answer
Outer Core
Because of the weight of the melting moving metal creates energy
Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.
What role of outer core of earth in magnetic field?Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.
The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.
The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.
Therefore, Because of the weight of the melting, moving metal creates energy.

What is condensation? Describe a way in which it can affect Earth systems.
12pt v
Paragraph
IB в I o Ауду т?у а
Answer:
Condensation is a process in which water vapors changed into liquid state.
Explanation:
Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

Mom has type O blood. Dad has type AB blood. What percentage of their kids will inherit type B blood?
Answer:
50%
Explanation:
Type A blood and type B blood are both dominant over type O blood.
A B
O AO BO
O AO BO
As is demonstrated by the Punnett square, the children's genotypes will either be AO or BO. Since type O blood is recessive, no child will have O blood, as other dominant alleles are present. 50% will have type A blood and 50% will have type B blood.
The only type of human cell that is never replaced is ___. *
Answer:
The only type of human cell that is never replaced is Nerve cells.
Hope this helps you. Do mark me as brainliest.
The only type of human cell that is never replaced is nerve cell.
What is a nerve cell?Neurons are in charge of receiving sensory input from the outside world, sending action potentials to our muscles, and transforming and relaying electrical signals at every step in the process.
The nerve cell is the basic unit of communication in the nervous system (neuron). The cell body, a major branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites).
They do not divide in any way. There are only two exceptions to this rule: only two specific areas of the brain can produce new neurons. However, for the most part, the brain is unable to replenish dead neurons.
Thus, nerve cells are the ones that never gets replaced after getting injured.

Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds. Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase. The figure shows two circular models, labeled Model A and Model B, that represent the cell cycle of fruit flies after fertilization. Model A represents cell cycles 1 through 13, and it contains two phases. Model B represents cell cycles 14 through 16, and it contains three phases.
What of the following explains the advantage of a G2 phase during embryonic development?
A Cells can undergo the cell cycle more quickly with a G 2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase.
D Cells are able to produce two new daughter cells with a G2 phase.
Answer:
C. Cells are checked for DNA damage before entering mitosis with a G2 phase.
Explanation:
G2 phase is very important phase of cell division in which cells are checked for DNA damage before entering mitosis with a G2 phase as well as correct duplication of the DNA is also verified and cell proteins that are necessary for cell division are also produced. This phase comes after S stage in which replication of DNA occurs so this G2 phase check the damages before starting of mitosis.

Damage to the brain can sometimes occur as the result of an accident.
State the part of the brain labeled A and suggest a problem that may be
experienced by a person who has damage to that part of the brain.
Answer:
A traumatic brain injury interferes with the way the brain normally works. When nerve cells in the brain are damaged, they can no longer send information to each other in the normal way. This causes changes in the person's behavior and abilities. The injury may cause different problems, depending upon which parts of the brain were damaged most.
