Answer: The options are not given, here are the options.
.a.prophase
b.prometaphase
c.metaphase
d.anaphase
e.telophase
The correct option is C.
Metaphase.
Explanation:
It is metaphase because during metaphase, the chromosomes lined up together and the two sister chromatids join to a particular spindle fiber. The microtubules them bring the sister together chromatids from the opposite spindle poles. The kinetochore microtubules capture the sister chromatids back and forth til they are able to form alignment along the equator of the cell which is called the equatorial plane.

Based on their half-life values, which radioisotope would be best suited to determine the age of a woolly mammoth bone
Answer:
Wolly mammoths existed about five million years ago. Therefore, based on their half-life, the radioisotope which would be best suited to determine the age of a wooly mammoth bone is Uranium - 235 whose half-life is approximately 700 million years.
Explanation:
Uranium 235 is a variant or an isotope of Uranium. Isotopes are a derivative of a particular chemical element which are alike but different in the number of nucleons they contain.
In relation to age testing, the time taken for any specified property to decrease by half of its original value is called a half-life.
Thus the radioactivity of Uranium - 235 takes about 700 million years to fall to half it's original value.
Because of its half-life, Uranium - 235 is the best used when dating very old fossils.

Controls and Variables – Read the description for each experiment and answer the questions. Krusty Krabs Breath Mints Mr. Krabs created a secret ingredient for a breath mint that he thinks will "cure" the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.
1. Which people are in the control group?
Answer:
The people in group B
Explanation:
The people in group B are those in the control group.
The control group during an experiment is a group of experimental subjects that either do not receive the treatment variable or are given placebo treatment. The control group is usually established to create a standard to which comparisons can be made during the course of investigating the effects of a particular variable.
In the case of Krusty Krabs, the group that was given regular breath mint without the secret ingredient (group B) will provide the basis for comparing with the other group that received the mint with the secret ingredient (A).
Hence, the people in group B served as the control group.
Hi plz help me with this :) It’d mean a lot. My work got deleted and I don’t remember this one.

One of the most common sources of phosphate pollution that has led to eutrophication has resulted from the use of
Answer:
Phosphate fertilizers
Explanation:
One of the most common sources of phosphate pollution is run-offs from phosphate fertilizer from agricultural processes. Farmers deploy phosphate-containing fertilizers to soils in other to improve the overall fertility of the soil and the yield of crops.
Some of these fertilizers find their ways into nearby water bodies through washing up by erosion thereby raising the phosphate levels of these water causing eutrophication.
Other common sources of phosphate pollution include industrial and domestic run-off as well as detergents although phosphate-containing detergents are now becoming a thing of the past.

A single base-pair mutation occurs in a promoter sequence of a gene. As a result of the mutation, what are the possible effects on the transcription level of the gene?
Answer:
This mutation could increase, reduce, have no effect, or even eliminate the transcriptional activity
Explanation:
A single pair mutation (also known as point mutation) is caused when only one nucleotide in the DNA sequence is changed. A promoter is a DNA sequence that binds to the RNA polymerase and transcription factors in order to initiate the transcription. When a point mutation results in a promoter region, this may alter transcription, and its effects can be determined by measuring the level of gene transcription. In a promoter bashing assay, point mutations are generated in the promoter region in order to determine their effects on gene expression.

Research has shown that the treadmill training increases the number of certain energy releasing structures in the brain cells of rats. Which cellular structure does this show
Answer:
Mitochondria
Explanation:
According to this question, treadmill training has been researchfully shown to increase the number of certain energy releasing structures in the brain cells of rats. The cell consists of certain structures that play specific roles called ORGANELLES.
One of these organelles called MITOCHONDRION is the one responsible for synthesizing energy in the cell. Hence, the mitochondrion is the structure being shown/depicted as the energy releasing structures in the rat's brain cells.
why is cytoplasm present in all cells?
Answer: Cytoplasm is present in all cells because it is the placeholder of the cell. It helps to fill in the cell and holds all the organelles in their place. If the cell did not have cytoplasm, the cell would be deflated and some certain materials would not have the ability to pass easily from one organelle to another. Hope this helps!
Explanation:
How might a reduction in species diversity affect the other three components of biodiversity?
Answer:
if the species diversity in an ecosystem or on the Earth gets reduced, it will affect the balance biodiversity and its other components. The three components of biodiversity are: ecosystem, species, and genetic diversity.
Biodiversity is defined as the variety of life forms existing in different ecosystems on planet Earth.
The three components of biodiversity are:
genetic diversity, species diversity, ecosystem diversity.If there is a reduction in the species diversity, there will be an imbalance in biodiversity, which is integrated, where each living being has an essential role in the maintenance and sustainability of the planet.
Biota reduction will therefore directly impact the ecosystem and will alter the correct flow of environmental balance.
It is possible to see through history, that many species of animals were extinct by human exploitation and this action cannot be reversed.
Therefore, it is essential to make each individual aware of the importance of developing sustainability for the preservation of nature and the quality of life of current and future generations.
