Explanation:
3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?
It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.
In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.
An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.
In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.
A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.
A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).
In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

How do limiting factors influence each other?
Answer:
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Other changes in limiting factors will cause a population to decrease.
Explanation:
hope it helps.
Answer: Two or more limiting factors may work in conjunction with one another.
Explanation: For example, parasites and disease. In this case, we have a biotic factor (parasites) combined with an abiotic factor (a disease-causing virus). Combining these limiting factors creates a deadly team that can have an even greater impact on a population's growth and survival.

Are there any differences between what we need as humans and what animals need? If so, what?
Answer:
Animal society is mainly based on instincts or reflex behavior, whereas human society is based on reason or rational behavior. There are no rights and duties in animal society. Every animal lives upon his physical powers whereas human society has a wonderful system of law and order.
Animals usually live in the wild where they have to find there own food and hunt for it, where we as humans spend money on our food and it is all at the grocery store. There are more differences but this is one main difference.

Which structure allows
gases and nutrients in
and out of the cell?
A. mitochondria
B. cytoplasm
C. nucleus
D. cell membrane
The cell membrane allows gases and nutrients in and out of the cell.
The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.
The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:
Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.
Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.
In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

Traditional antibiotics build immunity by exposing the memory cells of our body to inactive versions of viruses or bacteria.
True
False
Conventional antibiotics increase immunity by exposing our bodies' memory cells to dormant viruses or bacteria. So, the aforementioned is True.
What are Antibiotics?A particular class of antimicrobial agent that works against bacteria is an antibiotic. Antibiotic drugs are frequently used for the treatment and control of bacterial infections because they are the most effective type of effective antibacterial for doing so. Bacteria may be killed or have their growth suppressed.
Several types of bacterial infections are treated or prevented with the help of antibiotics. They either eradicate bacteria or stop them from proliferating and spreading.
Viral infections cannot be treated with antibiotics. This covers the typical cold, the flu, the majority of coughs, and sore throats. By introducing our bodies' immunological memory to latent viruses or bacteria, traditional antibiotics boost immunity.
