Why are white-eyed female fruit flies so rare in nature?
A. White-eyed females are not rare.
B. The allele for white eyes was nearly removed from the gene pool.
C. Females must inherit two copies of the recessive allele.
White-eyed female fruit flies so rarely in nature because females must inherit two copies of the recessive allele. Therefore, option C is correct.
Why are white-eyed female fruit flies so rare in nature?The gene for eye color in fruit flies is located on the X chromosome, and there are two possible alleles: one for red eyes (dominant) and one for white eyes (recessive).
Male fruit flies have only one X chromosome, so if they inherit the white-eyed allele, they will have white eyes. However, females have two X chromosomes, so they must inherit two copies of the white-eyed allele to have white eyes.
Because the white-eyed allele is recessive, it is much less common than the red-eyed allele in the gene pool. In nature, white-eyed female fruit flies are rare because they must inherit two copies of the recessive allele from both parents. Thus, option C is correct.

Answer:
1. Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
2. In 1965, Mariner 4 and 9 probes found geological formations (Olympus Mans). The Mariner 4 sent back the first image of Mars. The Mariner 9 found erosion marks that indicated that there was once water on Mars. In 1976, the Viking 1 and 2 probes transmitted panoramic views of the soils. From 1965 to 1976, they were able to discover more about Mars over improving the technology. When the Viking probes were launched, we discovered more than when the Mariner probes were launched. For example, we were able to uncover how red and rocky the soils were.
3. We now receive information differently thanks to wireless technology. For instance, we now have computers and phones that let us contact someone by simply pressing a button. GPS may now be used to display various places. Additionally, we can now forecast the weather. We can know the weather for every day because forecasters have access to a ton of technology. Thus, we now substitute archaic methods for digital ones.
4. Fire alarm and air conditioning systems include technologies that incorporate various communication systems that enable them to react to changes in the atmosphere or temperature. Therefore, when the atmosphere's temperature fluctuates, they are utilized.
5. Viking 1 and 2 were used to find life on Mars. Since they launched the Mainer probes, they found that there was once water on Mars which later created the Viking 1 and 2 probes for further investigation. Along with finding life on Mars, they were also created to take better photos of the planet.
From a trough to a peak, the economy goes through
The economy will then start to shrink as it descends from the peak and enters recession.
What is happening to the economy during the trough phase?The economy's growth rate declined during the depression phase. Up until the demand and supply for products and services, as well as the prices of the factors, reach their lowest point, there is still a further decrease. Eventually, the economy sinks to its lowest point. The economy enters the peak phase when it reaches its highest level of output, which marks the end of growth. After this, a contractionary phase occurs as employment levels and housing starts start to drop.
The time between an economic activity's peak and its subsequent trough, or lowest point, is known as a recession. The economic cycle between its trough and peak is one of expansion.

The mechanism through which a mother cell splits into two or more daughter cells is known as cell division.Cell division aids in the growth, maturation, healing, and production of reproductive cells in multicellular organisms (sperms and eggs). A poorly controlled process called uncontrolled cell division can lead to illnesses, most notably cancer.Binary fission is a method of prokaryote reproduction used by bacteria. Cell division is the sole process that unicellular organisms can use to create new individuals. The result of cell reproduction in both prokaryotic and eukaryotic cells is a couple of new cells which are genetically identical to their parent cell. Daughter cells are distinct entities in unicellular organisms.Therefore the correct answer is an option (B).

Which of the following is NOT a behavior of parental care?
A. Feeding
OB. Courtship displays
C. Protection from predators
D. Incubation of eggs
Parental care is the energy investment in looking after the progeny to ensure reproductive success, at the sacrifice of feeding, mating, and being save. The option is B. Courtship displays.
What is parental care?Parenting is a caring behavior chosen by some species in which parents invest energy in looking after their offspring to ensure their survival and hence, their reproductive success.
K-strategists are the species that perform parenting.
Animals must optimize the invested energy in growing, surviving, reproducing, and leaving fertile offspring. They must ensure the perpetuity of the species. The best way to do it is by reaching sexual maturity, mating, and leaving progeny that also reaches their fertile age. So species choose how to do it and where to invest more energy.
K strategists take care of their offspring and invest too much energy in doing it.
Parents must feed them, an activity that requires most of their energy to produce food or look for it. They must protect their progeny from potential opportunistic predators, so they need to be near the whole time. They need to teach behaviors and habits.And so many other things that require energy investment.
So, when parents take care of their offspring, the energy usually destined for survival and mating activities is now destined for parenting.
Often, parents can not feed because they can not leave their offspring alone. They face predators putting themselves in danger of being hurt. They can not mate even if they are in the reproductive season.
According to this framework, the correct option is Courtship displays. Option B. This is a typical pre-mating behavior in which sexual selection plays a significan role.

How can scientist explain our ability to feel empathy? Can evolution explain the types of group’s primates will organize themselves in? What is different about Homo sapiens from other non-human primates? Does this explanation make sense to you? Why or why not?
Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.
Can evolution explain the types of primates in the group into which they will organize themselves?As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.
How is Homo sapiens different from other non-human primates?Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"
With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.
