Why a litter of puppies with the same parents can all look different include words like gamete, zygote, chromosome, gene
Answer:
Because of the recobonation, not all the puppies will receive the same chromosomes from the parents. The genes can/will be transmitted differently and unequally between the puppies. These genes will be carried from the zygotes, the zygotes carry the genes from BOTH parents.
Puppies with the same parents can look different because of recombination.
What is recombination?Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles.
A Litter of puppies with same parents can all look different because of recombination. At the time of meiosis the number of chromosomes reduced and genetic recombination takes place.
Meiosis is a form of cell division that produces gametes. Meiosis is divided into different phases such as prophase, metaphase, anaphase and telophase. Crossing over takes place at pachytene stage. Cross over results in recombination and exchange of genetic material.
Recombination process creates genetic diversity and leads to variation. Chromosomes contains genes. When male and female cells fuses it leads to formation of zygote.
Therefore, Puppies with the same parents can look different because of recombination.

Having extra fingers (polydactyly) is a dominant trait. Having just 10 fingers is a recessive trait. How can you explain that almost (if not everyone) you know has the "normal" number of fingers? Look at the list of dominant vs recessive genes and give another example of a recessive gene being more common than a dominant one and explain why you think that dominance or recessiveness is not related to how often a trait occurs in a population
Answer:
Explanation:
Polydactyly is a mutation, it is a sudden change that can be heritable that occurs.
Because mutation does not always occur the chances of having large number of people having the traits in a dominant form is low, hence more people will have normal finger.
Dominance is not the number of time a traits occur, it is the ability of a allele to be expressed over another. The expressed allele i.e that is seen in the phenotype of such individual is the dominant allele while recessive allele are the one whose effect are mask.
Having a round eye is an example of a recessive traits that people posses but are expressed in some individual.
The overall population of a species has increased. What could have occurred to allow this to happen?
The emigration rate is greater than the death rate.
The death rate of the population is greater than the immigration.
The birth rate of the population is less than the death rate.
The immigration of the population is greater than the emigration.
Answer:
The correct answer is - The immigration of the population is greater than the emigration.
Explanation:
The growth of the overall population depends on the birth rate, immigration, emigration and death rate. The growth of the population can be calculated by subtracting the number of individuals removed or exited the population from the number of individual come into the population.
Among the given options the best choice is the number of immigration is higher than the number of individual emigrated from the population that means the population growth is increased.

All organisms need energy from food. Which best describes
the process of how plants and animals get usable energy
from food?
Answer:
Plants build carbohydrates using light energy from the sun (during the process of photosynthesis), while animals eat plants or other animals to obtain carbohydrates.
Explanation:
Animals eat plants or other animals to obtain carbohydrates, whereas plants create them using the sun's light energy and the process is called photosynthesis.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
The process of photosynthesis is unique to plants since only those with the food-making chlorophyll pigment can carry it out. The necessary elements are sunlight, water, and oxygen, where two processes take place: one that depends on light, the other that doesn't.
Thus, animals eat plants or other animals to obtain carbohydrates, whereas plants create them using the sun's light energy and the process is called photosynthesis.

Identify the molecules in the plasma membrane that provide basic membrane structure, cell identity, and membrane fluidity.
The main molecules present in the plasma membrane are phospholipids, those molecules are made of a polar, hydrophil end(glycerol with a phosphate group attached) and two non-polar, hydrophobe ends(two fatty acids rests). The cell identity is determined by proteins present in the membrane, a very important type of protein that determines the identity of a specific cell is called marker. The membrane fluidity is reduced by a lipid with a ring structure, cholesterol, this molecule belongs to a class of biomolecules called steroids.
Phospholipids are the fundamental constituents of all cell membranes. They are amphipathic molecules made up of two hydrophobic fatty acid chains joined to a hydrophilic head group that contains phosphate.
What is membrane fluidity?Because of its dynamic structure, proteins, and phospholipids can move about freely. The ability of molecules to move freely within the membrane is referred to as “fluidity,” which is crucial for cell activity.
Membrane composition and temperature affect membrane fluidity. Both membrane composition and temperature modify a membrane's fluidity, or how freely the membrane's constituents can move.
In order for cell membranes to work effectively, they must balance fluidity—which allows proteins and lipids to move around inside the membrane—with membrane curvature, bending, budding, and fusing.
A lipid with a ring structure, cholesterol, which is a member of the class of macromolecules known as steroids, reduces the fluidity of the membrane
Therefore, Phospholipids that provide basic membrane structure, cell identity, and membrane fluidity.

Which of the following situation demonstrates a physical change
Answer: c melting ice
Explanation:
In the 1970s many experts thought that the fight against infectious diseases was over. In fact, in 1970, the Surgeon-General of the United States of America indicated that it was "time to close the book on infectious diseases, declare the war against pestilence won, and shift national resources to such chronic problems as cancer and heart disease".
During the last two decades, this opinion has been reversed, and there is now a renewed appreciation of the importance of infectious disease. The spread of new diseases such as HIV/AIDS, hepatitis C, and dengue hemorrhagic fever, and the resurgence of diseases long since considered under control such as malaria, cholera, and sleeping sickness, have drawn considerable attention. Over the past 200 years there have been multiple devastating outbreaks of cholera caused by the bacteria, V. cholerae. Cholera is an infectious and deadly bacterial disease that affects the small intestine. The infection causes severe vomiting and diarrhea. The infection is typically spread from person to person and through infected food and water.
In 1832, there was a cholera outbreak in New York City that killed 3,515 people or 1.5% of the city's population. New York was struggling to keep up with the growing population, the city was overcrowded, there was a lack of sanitation, and science did not yet recognize the role of germs in disease. Cholera overwhelmingly affected the poorest neighborhoods in the city, hitting African-Americans and immigrant Irish Catholics the most. Many of the high income people from the city were able to leave the city and prevent themselves from getting sick.
In 2010, an outbreak of cholera was confirmed in Haiti for the first time in more than 100 years just ten months after the catastrophic earthquake killed over 200,000 people and left over 1 million people without a secure place to live. In this outbreak there were over 665,000 cases and 8,183 people died. A more recent outbreak of cholera occurred in Kenya in 2017 with 3,967 confirmed cases and 76 deaths. Epidemiologists believe the disease was transmitted during mass gathering events and at refugee camps within the country.
Scientists are concerned because they noticed that some antibiotics used to treat cholera are not working as well as they have in the past. Furthermore, the vaccine for cholera is not always effective in the long term and is not a commonly given immunization by most doctors. Researchers have estimated the bacteria, V. cholerae may infect between 1.3 and 4 million people and cause 21,000 to 143,000 deaths worldwide a year. How could we prevent a severe outbreak in the future?
Questions
What factor(s) were the same in the cholera outbreaks of 1832, 2010, and 2017?
Based on this phenomenon, what is a problem we are currently facing?
What are some initial ideas on how to solve it?
Of the many different strains (types) of V. cholerae, only a few cause pandemic disease. A pandemic is an outbreak of a disease that occurs worldwide or over a very large geographical area. There have been six cholera pandemics recorded since 1816. The seventh pandemic was first seen in El Tor, Egypt and continues on to this day.
I think the 7 was the longest becuase it lasted 50 to 60 years i guess am i right

If you wanted to design an artificial hormone who's action on a target cell required the least amount of interaction with that cell, what type of hormone would you want to use and explain why. *
Answer:
The water soluble hormones affect the target cells with least amount of interaction.
Explanation:
Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.
Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.
On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule.
Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones.
