Chromosomes are paired but genes are not. True/ False
Answer:
False
Explanation:
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
A geneticist at Chicago's Brookfield Zoo is attempting to mate two gorillas. The gorillas are
both heterozygous for hair color and hair length as represented by the following genotypes:
CcLI X CcLl. Use the rules of probability to determine the chance of this mating producing
an offspring that is cell.
The genotypes CcLl 3 CcLl show that the gorillas both are heterozygous for hair colour and hair length.
Dominant fatal alleles are extremely uncommon since, as one might anticipate, they only exist for one generation and are not passed along. However, just as the dominant lethal gene might not have been expressed until adulthood, recessive lethal alleles might not immediately display the death phenotype. Is it possible to tell if a baby has an autosomal disease like cystic fibrosis by looking at their karyotype? Explain your response in a few words. No, a karyotype simply shows the chromosomes of an organism and not the genes that are located on those chromosomes.

a doctor suspects one of his patients has melanoma (a type of cancer). he takes a very small biopsy, about 1 mm cube, from a suspicious mole. this biopsy would contain about how many cells?
Answer:
1000
Explanation:
Trust me
The biopsy would contain approximately 1 million cells.
To estimate the number of cells in the biopsy, we can use a rough approximation that a cubic millimeter of tissue contains about 1 million cells. This estimation is based on the average size of cells and their packing density within tissues. It's important to note that cell sizes can vary widely, and the actual number of cells in the biopsy may vary accordingly.
The estimation is derived from the consideration of cell size and the concept of cell density in tissues. In a typical tissue, cells are densely packed, and their sizes vary depending on the tissue type and cell type. Given that the biopsy is very small (1 mm cube) and considering the typical size and density of cells in tissues, an approximation of around 1 million cells is reasonable.
This estimation helps to provide a general understanding of the number of cells that might be present in the biopsy. However, the actual number of cells could be influenced by factors such as tissue type, cellular organization, and the presence of other cell types, as well as any potential variations in cell sizes.

The probability that a male child will be colorblind in this scenario is 100%.
What is the probability that male child will be colorblind in this case?The probability that the male child will be colorblind in this scenario is 100%.
This is because the gene for color blindness is located on X chromosome, and men only have one X chromosome (and one Y chromosome). If man is colorblind, then it means that he has inherited non-functioning allele for gene on his X chromosome and he will pass it on to his sons.
As sons inherit their X chromosome from their mother, and mother in this scenario is heterozygous for the gene (meaning she has one functioning allele and one non-functioning allele), there is 50% chance that she will pass on the non-functioning allele to her son.

Is starch structural or energy?
The primary purpose of starch is to help plants store energy.
Starch seems to be a complex polysaccharide made of a chain of covalently bonded glucose molecules. Pure starch is a tasteless, odourless, white powder derived from plants that is a significant component of modern human diets. Starch is generated by most green plants to store excess glucose produced during photosynthesis.
In mammals, glycogen is a more heavily branched polymer containing glucose monomers that serves as an energy store molecule. Glycogen is mostly synthesised and stored in liver and muscle cells. When they need to consume more energy than photosynthesis provides, they trap glucose as part of a carbohydrate molecule or break off smaller glucose units. Starchy foods are generally safe for most people and pose no dangers or adverse effects. However, those with diabetes or CSID should exercise caution when it comes to starch consumption.

what are the two types of adaptive immunity, and what types of microbes do these adaptive immune responses combat? 2. what are the principal classes of lymphocytes, and how do they differ in function? 3. what are the important differences among naive, effector, and memory t and b lymphocytes? 4. where are t and b lymphocytes located in lymph nodes, and how is their anatomic separation maintained? 5. how do naive and effector t lymphocytes differ in their patterns of migration?
The adaptive immune system is composed of two branches: humoral and cellular immunity. B and T lymphocytes are the two main types of lymphocytes that are involved in adaptive immunity and they have different functions and migration patterns.
1. Types of Adaptive Immunity and Microbes BattledThe two types of adaptive immunity are humoral and cellular immunity. Humoral immunity involves the production of antibodies, which are proteins that bind to and neutralize specific antigens, such as bacteria, viruses, and other foreign substances. Cellular immunity involves the activation of T-cells, which attack and destroy infected cells directly. Both of these adaptive immune responses are important for combating pathogens, including bacteria, viruses, fungi, and parasites.
2. Differences in Function Between B Cells and T CellsThe principal classes of lymphocytes are B cells and T cells. B cells are responsible for the production of antibodies, which help to fight off invading pathogens. T cells are responsible for recognizing and destroying foreign bodies, such as viruses and bacteria. While both B cells and T cells work together to protect the body, they do so in different ways. B cells produce antibodies which bind to and neutralize pathogens, while T cells recognize and destroy foreign bodies.
3. Differences between Naive, Effector, and Memory T and B LymphocytesNaive T and B lymphocytes are the naive cells that are found in the lymphatic system ready to respond to antigens. They have not been exposed to any antigen before and are ready to respond to a new antigen. Effector T and B lymphocytes are the cells that have been exposed to an antigen, and they are responsible for mounting an immune response. Memory T and B lymphocytes are the cells that remain in the body after an immune response has been mounted. They are responsible for providing a rapid response to a previously encountered antigen, allowing for a faster and more effective immune response.
4. The Anatomic Separation of T and B Lymphocytes in Lymph NodesT and B lymphocytes are located in different regions of the lymph node. T lymphocytes are found predominantly in the paracortex, while B lymphocytes are found in the more central area called the follicles. The anatomic separation is maintained by the specialized reticular network of the lymph node, which is composed of reticular fibers and reticular cells. The reticular network acts as a physical barrier between the two regions of the lymph node, ensuring that the T and B lymphocytes are kept separate.
5. Difference in Migration Patterns Between Naive and Effector T LymphocytesNaive T lymphocytes typically migrate to the lymph nodes and spleen, where they are exposed to antigens and can differentiate into effector T lymphocytes. Effector T lymphocytes typically migrate directly to peripheral tissues and organs, where they can initiate an immune response.

Which form of selection produces the strongest organism that is able to survive in the wild on its own?
The strongest creature that can live in the wild unaided is produced by natural selection.
Natural selection is a mechanism of evolution. Environment-adapted creatures are more likely to endure and pass on the genes that made them successful. This technique eventually causes species to evolve and diverge.
For instance, giraffes have an advantage over other species because of their long necks, which have made it possible for them to graze on leaves that other species cannot. Individuals with longer necks were able to reproduce and pass the trait on to the following generation because they had access to more food.

D.the genetic mixing of different populations of the same species
The most advantageous features enable an individual to survive and procreate. The method by which population of living things adapt and change is known as natural selection.
A population's members are naturally varied, which means that they are all distinctive in some ways. This variation indicates that some people have characteristics that are more environment-appropriate than others. Natural selection, commonly referred to as "survival of the fittest," is the more frequent reproduction of people who possess advantageous qualities and who, as a result of those traits, are able to withstand environmental change. As a result, the trait evolves and eventually takes over a population. Genetic diversity is necessary, modified descent occurs, and varying levels of reproductive success are present.
