1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.

2. When cells duplicate, they need to ensure that one complete copy of all of the DNA the cell contains ends up
in each cell. Which way of organizing DNA best ensure that each new cell contains a complete set of the
instructions it needs for performing life functions?
mitochondrial
Why?
HELP ASAP
Answer:DNA replication is the copying of DNA that occurs before cell division can take place. After a great deal of debate and experimentation, the general method of DNA replication was deduced in 1958 by two scientists in California, Matthew Meselson and Franklin Stahl.
DNA Replication. DNA replication faithfully duplicates the entire genome of the cell. During DNA replication, a number of different enzymes work together to pull apart the two strands so each strand can be used as a template to synthesize new complementary strands. The two new daughter DNA molecules each contain one pre-existing strand and one newly synthesized strand. Thus, DNA replication is said to be “semiconservative.”

What type of mutation occurred in the following? Normal allele GGAAUGAAACAGGAACCC Mutant allele GGAAUGAAAUCAGGAACCC
Answer:
Insertion
Explanation:
Mutation is a sudden change that occurs in the genome of an organism that is heritable i.e it can be transfer from parent to offspring. There are different types of mutation Missense, nonsense, Insertion.
Insertion is a type of mutation that involves addition of extra Nitrogenous base that was not originally in the DNA strand. This will increase the number of the DNA strand and may also affect the function of protein to be formed
The mutant strand contains Uracil(U) which was not in the normal DNA strand which indicates insertion type of mutation.
GGAAUGAAACAGGAACCC -Normal
GGAAUGAAA U CAGGAACCC- Mutant

Answer: d edge 2021
Explanation:
when does mutation have the greatest effect; translation, RNA synthesis, DNA Replication or somatic cell formation?
Answer:
It depends on the specific cell type that suffers the mutation. For example, in stem cells, it is reasonable to expect that mutations in the genes involved in DNA replication will have critical consequences
Explanation:
A mutation is a genetic modification in the DNA sequence due to errors during the mechanism of DNA replication or by the effects of environmental (mutagenic) factors. A mutation in the germline can be inherited in the next generations, while a mutation in somatic cells is not inherited. Moreover, a mutation affecting RNA synthesis may have diverse effects depending on the function of the gene involved in this mutation. In a similar mode, a mutation in one gene associated with the mechanism of DNA replication can have critical consequences on the cells originated from the mutated parental cell, but again it is variable and generalizations can not be made without knowledge of the cell type suffering this modification.
Which of the following is generally expected to be true about birth rate. in relation to death rates for a country with growing population and high infant mortality?
A. Variable compared to death rates
B. Equal to death rates
C. Lower than death rates
D. Higher than death rates
Answer:
D
Explanation:
If the country has a high infact mortality rate, then a lot of babies are dying, but because the population is still growing, then the birth rate must be high to make up for the deaths and grow. Countries that have high birth and death rates are usually developing or least developed countries that don't have access to medical care and knowledge about family planning.
'Birth rate' is characterized as "the total number of live infant births in a year in comparison to the whole population under a specified period of time."
The statement that asserts a true claim regarding 'birth rate' in association with death rates would be that
D). "the birth rates would be higher than death rates."
'Infant Mortality rate' is defined as the "the total number of infant deaths in a year under one year of age for every thousand live births" while the 'birth rate' is referred to as 'the number of births on every thousand population each year.'In the case of a country whose population is growing, it is evident that the birth rate of that country in association with infant mortality is higher. This implies that the number of children who take birth every year is greater than the number of kids who die every year leading the population to increase.Thus, option D is the correct answer.

When glycogen phosphorylase is phosphorylated Group of answer choices its activity decreases. its activity increases. its activity is unaffected. none of these because that enzyme doesn't get phosphorylated.
Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.

In many suburban
neighborhoods, houses are spread
very regularly across the
landscape. The humans in the
neighborhood have a
dispersal pattern.
The humans in the neighborhood where houses are spread regularly have a uniform dispersal pattern.
Spatial distribution of populationsThe spatial distribution of populations refers to the pattern of distribution of individuals within the population.
Individuals within a population are dispersed based on factors such as the availability of food, access to roads, etc. This is otherwise known as an active movement.
In other instances, individuals within the population are moved passively by factors such as wind, water, presence of other individuals.
Individuals within a population can be distributed in one of 3 ways:
Random distribution: when individuals are distributed in such a way that no specific pattern is formed. Clumped distribution: when individuals within a population are concentrated to a specific point or clumped together.Uniform distribution: when individuals that make up a population are distributed regularly across the entire area covered by the population.In a random distribution, houses are also likely to be randomly sited across the population area. In clumped population distribution, houses are usually clumped together. In uniform population distribution, houses are usually regularly spread across the landscape covering the area of the population.

Here the in the above scenario there are 8 wells in which sample (soap), negative and positive control are performed in duplicate.
At the result the negative control in one well, it is negative but in other well it is positive which shows that the test in invalid. And we cannot interpret on the basis of these test results because for our test validity both negative control samples should be negative.
Drag each label to the correct location. Each label can be used more than once. In a hydropower station, water stored in dams is allowed to fall with force to make a turbine move. The turbine moves and produces electricity. In the diagram, identify the stages of transformation of energy in the hydropower station. Please help!!
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy
Explanation:
Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.
When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.
As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.
Kinetic energy is transformed to electric energy and transmitted along powerlines.
*See attachment below for labelled energy that is being transformed at several points.
