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.

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.

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.

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.

Gina is studying a cell under a powerful microscope. The cell does not contain membrane-bound organelles.
Which cell is Gina most likely studying?
The cell that Gina is studying under the powerful microscope does not contain membrane-bound organelles. Hence, it is most likely a prokaryotic cell.
Prokaryotic cells differ from their eukaryotic counterparts in that:
they lack nucleusthey are smaller in sizethey lack membrane-bound organelles such as mitochondrion, chloroplast, etc.Prokaryotic cells lack nucleus and as a result, their genetic materials lie freely within the cytoplasm. They are also smaller in size when compared to eukaryotic cells with the former's size ranging from 0.1 to 5 micrometers and the latter ranging from 10 to 100 micrometers. Specialized organelles such as mitochondrion and chloroplasts are lacking in prokaryotic cells due to their primitive nature.
Therefore, once a cell is known to lack membrane-bound organelle, it will most likely be a prokaryotic cell.

¿En el Perú, en qué tipos de energías renovables se están realizando inversiones ? ¿Por qué? ¿Cuál de los dos tipos de energías que hemos analizado nos ayuda a reducir el calentamiento global y por qué?
Answer:
Energía, Cambio Climático y Centro de Energías Renovables y empleo
Ver todo en esta sección
El vínculo entre la energía y el cambio climático es muy fuerte. De hecho, ha sido el altísimo consumo de energías fósiles lo que ha provocado el calentamiento del clima que ya sufrimos y que seguiremos experimentando en las próximas décadas.
Desde el inicio de la era industrial, el consumo de energía proveniente de los combustibles fósiles -carbón, petróleo y gas natural- ha ido en aumento. La sociedad, tal y como la conocemos hasta ahora, está basada en estas fuentes de energía y en ellas hemos basado nuestra economía. Pero la quema de los combustibles fósiles es la responsable de la producción de los gases de efecto invernadero, causantes del calentamiento global.

the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
Explanation:
IN YOUR OWN WORDS, what are the definitions for these words?
1. Gamete:
2. Zygote:
3.Interkinesis (include when it happens):
4. Kinetochore:
5. Haploid:
Gamete;
When the zygote resulting from fertilization of an ovum (female sex cell) continues to grow, producing new cells by mitosis. This will continue until it reaches sexual maturity and then produce new cells by meiosis. These new cells, the germ cells gives rise to sex cells or the gametes.
Zygote;
The result of uniting the sex cells i.e the sperm and the egg is a zygote
Interkinesis;
Or interphase II is a period of rest that cells of some species enter during meiosis between meiosis I and meiosis II. During interkinesis, the single spindle of the first meiotic division disassembles and the the micro tubules reassemble, into two new spindle for the second meiotic division.
Kinetochore;
This is the protein complex assembled on the centromeric region of DNA. It provides the major attachment point for the spindle microtubles during mitotic or meiotic division to pull the chromosomes apart.
Haploid;
This is the quality of a cell or organism having a single set of chromosomes. Organisms that produce asexually are haploid organisms
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.
