In which mitotic phase does the process of cytokinesis conclude? (1 point)
O interphase.
O telophase
O prophase.
O metaphase.
Answers
When cytokinesis reaches telophase, it has completed the mitotic phase.
Explain about the telophase?Each set of chromosomes produces a nuclear membrane that separates the nuclear DNA from the cytoplasm during telophase. The chromosomes become less tightly wound and more dispersed as a result of uncoiling.
After telophase, there is a process known as cytokinesis in which the cytoplasm is divided into two daughter cells. The outcome of this technique is the generation of genetically identical daughter cells. In mitosis, an even division of each duplicate chromosome occurs. Two identical nuclei are consequently formed during telophase. Because they will behave in the same way, these cells can be used to regenerate damaged cells or to produce complete beings from a single zygote.

In Activity 2, which of the respirometers serves as a control? Explain your answer! Why was it the control? You should write at least 3 sentences to explain this. Respirometer A contains germinated beans. respirometer B contains dormant beans and plastic beads respirometer C contains plastic beads.
Answers
In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.
Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.
This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

If an existing ecosystem is destroyed, _____________.
A) primary succession occurs
B) secondary succession occurs
C) a climax community comes into existence
D) a different type of biome emerges
Answers
Answer:
Option B
Explanation:
The answer is option B or "secondary succession occurs." Secondary succession is when an ecosystem is destroyed but because of some key factors such as surviving animals, soil, and other natural resources, those resources then bring the ecosystem back to life. Common ways secondary succession occurs is when you clear out land from trees, and wildlife. The soil of that land is still there, which means that soil will start the growth of grass, and new animals will come back to eat that grass, that land will slowly start to become an ecosystem again.

Therefore, a theory cannot be created by just one person without extensive research and experimentation, and without undergoing peer review to ensure its validity.
Which statement is accurate about evolution?
A) The environment selects for traits that are a good fit. These traits survive in a population and over many generations, the genetic make up of the population changes.
B) As the environment changes, organisms adapt and change to survive. Organisms adapting and changing during their lifetime leads to evolution of the population.
C) Mutations occur regardless of the environment. These mutations will always lead to evolution of the population.
D) Regardless of the environmental change, the genetic frequencies of a population always stay the same. Evolution occurs when there is no change in the population over time.
Answers
As the environment changes, organisms adapt and change to survive. Organisms adapting and changing during their lifetime leads to evolution of the population. Thus option B is correct.
Why did evolution occur?
Evolution is the shift in inherited characteristics among biological populations over successive generations. These characteristics are the results of genes that are passed from parents to children during reproduction. Any given group experiences variation due to genetic recombination and mutation.
Due to the effects of natural selection (including sexual selection) and genetic drift on this diversity, certain traits may become more common or rare within a population. Through succeeding generations, heritable traits will change as a result of shifting evolutionary forces that determine whether a feature is common or rare within a population. At all levels of biological organization, this evolutionary process is what gives rise to biodiversity.

All of the following are adaptations of herbivores EXCEPT:
A. flat teeth for chewing tough plant matter
B.special digestive systems for digesting plant cellulose
C.coat colors that help them blend in with the land
D. keen eyesight for spotting prey
ALSO NEED ANSWERS ASAP!!
Answers
Apart for acute eyesight for finding prey, all of the above are adaptations of herbivores.
What adaptations do herbivores have?The big, flat, and rough surfaces of a herbivore's molars crush the tough plant tissues (back teeth). Many herbivores, including squirrels, have front teeth with chisel-like edges for breaking through tough objects like wood or seeds. These teeth are constantly growing in order to prevent wear and tear.
What modifications does a herbivore have for cellulose digestion?Herbivores must rely on mutualistic, internal symbiotic bacteria, fungi, or protozoa to break down complex cellulose in order for the herbivore to consume it. By detoxifying plant secondary metabolites, microbial symbionts also enable herbivores to consume plants that might otherwise be poisonous.

have hairs filled with poison. (6) If a predator eats one of these larvae, it may suffer a toxic reaction. (7) Insects that
defend themselves by unpleasant or dangerous chemicals gain two advantages. (8) On one hand, they often deter a
predator from eating them. (9) On the other hand, predators learn not to bother them in the first place.
(10) Other insects gain protection by mimicry, or similarity of appearance. (11) In one kind of mimicry, insects with similar
defense mechanisms look alike, and predators leam to avoid them all. (12) Bees and wasps mimic each other in this
way. (13) In another kind of mimicry, insects with no defenses of their own mimic the appearance of stinging or bad-
tasting insects (14) Predators avoid the mimic as well as the insect with the unpleasant taste or sting (15) For example,
syrphid flies look like bees but do not sting.
(16) Another kind of defense based on appearance is camouflage, or the ability to blend into surroundings. (17) Many
kinds of insects and animals have distinctive color markings that make them difficult to see. (18) Predators have trouble

Answers
Insects employ various strategies to protect themselves from predators. They may use chemical defenses, such as secreting foul-smelling chemicals or possessing poisonous stings. Additionally, some insect larvae have poisonous hairs that can cause toxic reactions in predators. Insects that rely on unpleasant or dangerous chemicals gain two advantages: deterring predators from eating them and teaching predators to avoid them altogether.
The passage describes various defense mechanisms employed by insects to protect themselves from predators. Insects have evolved a range of strategies to deter or escape from threats.
These strategies include chemical defenses, mimicry, and camouflage. Chemical defenses involve the secretion of foul-smelling chemicals or the possession of poisonous stings, which discourage predators from attacking or eating them.
Mimicry involves insects with similar defense mechanisms resembling each other, leading predators to avoid them altogether. Some insects mimic the appearance of other species with unpleasant tastes or stings, deterring predators.
Camouflage is another defense mechanism, enabling insects to blend into their surroundings and make it difficult for predators to spot them. These defense mechanisms increase the chances of survival and successful reproduction for insects, as they are better equipped to defend themselves against potential threats.

C. Studying DNA sequences from related organisms
D. Examining structures during an organism's early stages of development
Answers
The action that might produce biochemical evidence that supports the theory of evolution is C. Studying DNA sequences from related organisms
By comparing the DNA sequences of similar animals, it is possible to find biochemical proof that the theory of evolution is correct. All living organisms on Earth are said to have descended from a common ancestor and evolved from it through a process known as descent with modification, in accordance with theory of evolution. Therefore, closely related species should share more DNA than those that are unrelated.
Scientists may compare the DNA sequences of various creatures and find similarities and differences thanks to DNA sequencing technologies. Scientists can reconstruct the evolutionary links of animals and establish how closely related they are by examining the variations in DNA sequences between them.

Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria
Answers
The reason for the clear zone may be that there is Insufficient lipolytic activity.
Why the clear zone?The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.
Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media.
