How can a pure white mouse help determine the genotype of a black mouse? (Hint: We cannot see genotype but we can see differences in the phenotype of their offspring).
Answer:
A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.
Explanation:
If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.

Explanation:
Investigators interested in studying the activation of apoptosis inject cytochrome c into the cytosol of two types of mammalian cells: cells that are normal and cells in which Bak and Bax have been inactivated by mutation. How would these cells be predicted to respond? Question 3 options: The normal cells will undergo apoptosis and the mutant cells will continue to grow. The mutant cells will undergo apoptosis and the normal cells will continue to grow. Neither cell type will undergo apoptosis, so both will continue to grow. The normal cells will undergo apoptosis and the mutant cells will die by necrosis. Both cell types will undergo apoptosis.
Answer: Both cell types will undergo aptosis
Explanation:
cells lacking both Bax and Bak, but not cells lacking only one of these components, are completely resistant to tBID-induced cytochrome c release and apoptosis. Moreover, doubly deficient cells are resistant to multiple apoptotic stimuli that act through disruption of mitochondrial function: staurosporine, ultraviolet radiation, growth factor deprivation, etoposide, and the endoplasmic reticulum stress stimuli thapsigargin and tunicamycin. Thus, activation of a “multidomain” proapoptotic member, BAX or BAK, appears to be an essential gateway to mitochondrial dysfunction required for cell death in response to diverse stimuli.

A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the mutation?
Answer:
The sequence would be ATTCATTCA.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out. Trust me, it's a great video, it's much better than my explanation.
A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
O density dependent
O density independent
O population dependent
O population independent
Answer:
Density independent is the correct answer
The type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.
What are density-independent factors?Density-independent factors are environmental factors that affect populations regardless of their size or density. These factors can include natural disasters such as forest fires, floods, hurricanes, droughts, and other extreme weather events. Other examples of density-independent factors include habitat destruction, pollution, and climate change. In the scenario described, a forest fire destroyed an area, which can lead to the decline of both tree and bird populations. The fire could kill the trees and destroy their habitats, making it difficult for the surviving trees to grow or reproduce.
Hence, the type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

IN YOUR OWN WORDS, what are the definitions for Interkinesis (include when it happens)?
INTERKINESIS:
Interkinesis is also known as interphase II that occurs during meiosis, between meiosis I and meiosis II.
No DNA replication takes place during this phase.
Specifically in plants when two daughter cells are produce by the process of meiosis I, immediately they prepare for meiosis II.
During this period nuclear envelope begin to appear for temporary, which is known as interkinesis that helps in the separation of two sets of chromosomes.

Which of the following most accurately describes most scientists' current understanding of the evolution of humans?
A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.
Answer:
B: Humans, chimpanzees, and other primates share a common ancestor.
Explanation:
According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.
Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.
An astronomer measures the distance to two stars using the parallax method. When comparing the placement of the stars six months apart, the star that is further away: A. Changes position the most B. Changes position the least C. Appears brighter D. Appears dimmer
Answer:
I would say A but im not 100% sure
Explanation:
The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.
What is the parallax technique?The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.
It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.
Therefore, the star located farthest will change its position the most.

Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean. The results of the Lohmanns' experiments are most likely to be considered credible if Group of answer choices a great deal of time had been spent collecting hatchlings and running experiments. the experiments were funded by a government grant. the results were published in a peer-reviewed journal. the Lohmanns are famous scientists.
Answer:
the results were published in a peer-reviewed journal.
Explanation:
When the results of any study or a research is published in a well renowned and a peer reviewed journal, then the study is considered to be credible and authentic and is accepted by the intellectual society.
In the context, two young scientists are performing an experiment on the direction finding or the orientation finding abilities of the loggerhead sea turtle which are hatching under the varying magnetic fields.
The finding of these experiment or the result will be considered credible only when the results of the experiment will be published in a peer reviewed journal.
