help me its timed pleasee
Answer
neucleus
Explanation:
I mark Branliest for the correct answer quickly please listen to me Eyes Blue
Answer:
1(i think)
Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.
Which of these occurs in sexual reproduction but not in asexual reproduction?
a
The genetic information is identical to the parents.
b
The offspring are made of cells.
c
The genetic information comes from the parents but is not identical.
d
The offspring inherit traits from the parents.
Answer:
c
Explanation:
Only in asexual reproduction the genetic information is identical. Sexual produces genetics that are combination of both parents, producing non-identical offspring.

Which statement about natural selection is most correct?
a) adaptations beneficial in one habitat should generally be beneficial in all other habitats as well
b) different species that occupy the same habitat will adapt to that habitat by undergoing the same genetic changes
c) adaptations beneficial at one time should generally be beneficial during all other times as well
d) well adapted individuals leave more offspring and thus contribute more to the next generations gene pool, than do poorly adapted individuals
Answer:
The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.

Which material would be used if the main criterion was keeping the cost of materials as low as possible? Which material would be used if the main criterion was getting the best performance from the material
Answer:
Low cost has low quality whereas high cost has high quality.
Explanation:
If the main criterion was keeping the cost of materials as low as possible so he must used the materials of low quality for their work because the low quality materials are made of cheap material while on the other hand, if the main criterion was getting the best performance from the material so he has to used the materials of high quality. The high quality materials are very expensive but its performance is excellent as compared to cheap materials.
When identifying the agent responsible for causing a disease, why is evaluation of colony morphology not enough?
Answer:
Some infectious diseases are distinctive enough to be identified clinically. ... Infections may be caused by bacteria, viruses, fungi, and parasites. ... Microbial Identification: Colony and cellular morphology may permit preliminary ... Diagnostic medical microbiology is the discipline that identifies etiologic agents of disease.
Explanation:
Microorganisms have antigens present on their surface, Antigen tests detect the presence of a microorganism directly so that doctors can diagnose an infection quickly, without waiting for a person to produce antibodies in response to the microorganism.
Evaluation of colony morphology is not enough as it is not a definitive test. colonies of different bacteria can look the same, so it can help narrow.
What is antigen tests?An antigen test is an immunoassays test used for the detection of a specific viral antigen that indicates current viral infections.
Hence, Antigen tests detect the presence of a microorganism whereas, Evaluation of colony morphology is not enough as it is not a definitive test.

Which statement best describes how cell theory relates to a stem cell's ability to
change into specialized cell types?
The stem cells have the unique ability to undergo cellular differentiation which results into formation of a more specialized cell type which performs a unique function in body. Such as blood cells, neurons, etc.
What is Cell theory?
Cell theory has been proposed which describes various properties of a cell and how these cells develop. The theory has given some postulates and one of these postulates is that the new cells originate from pre-existing cells. Thus, the cell theory explains that the specialized cells which are present in body are synthesized from the stem cells.
Under the favorable conditions, the stem cells divide to form specialized daughter cells. These daughter cells become either a new stem cell or the specialized cells with a more specific function which includes blood cells, neurons, muscle cells or bone cells.

what type of destruction result in primary succession
Answer:
Destruction that ends with the creation of new land, like a volcanic eruption
Explanation:
Primary succession refers to how life comes to be in a new land that has never been inhabited before. So any type of destruction that creates land that has never supported life would cause primary succession. Volcanic eruptions is the most common type of destruction for primary succession because the lava cools and becomes new land. Primary succession is defined by succession occurring in an area that does not have any soil for life to grow on.

Describe the Lysogenic cycle.
No dam links
Answer:
Here ya go
Explanation:
The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.
