Explain why parents and children don't look exactly alike by posting on the discussion board. Use the vocabulary words: chromosomes, DNA, inherited traits, and mutations in your explanation.
Answer:
Explanation:
Deoxyibonucliec acid(DNA) contains the genetic constituent of an individual for a child or an individual he inherits equal proportion of genetic make up or traits from both mother and father hence, the genetic constituent of a child is never 100% mother or 100% father but a blend of the two to give a new genetic makeup that have never existed before and cannot be entirely identical with either parents but 50% identical with each parent.
Mutation is a sudden change in genome of an organism that is heritable, mutation alters the genetic constituent making it different from the original plan hence, if mutation should occur an individual could have a look that is not identical with the parent because the physical expression is the function of the genetic make up.
Chromosome crossing over effect could also alter the make up of an individual making it different from parental gene.

What is the density of a 700 kg object with a volume of 649 m3? (Density: D = D = m over v.) 0.927 kg/m3 .4543 kg/m3 1.079 kg/m3 4.543 kg/m3
Answer:
0.927 kg/m3
Explanation:
The density of a 700 kg object with a volume of 649 m30 is 927 kg/m3. Thus, option A is correct.
This problem is solved using density = mass /volume formula
mass= 700 kg
volume= 649 m³
density is therefore = 700 kg / 649 m³ = 1.079 kg/m³
What is density?Density has been calculated by dividing an object’s mass by its volume. The density of the water is generally 1,000 kg/m3 at 4°C. The unit of density has been kg/m3 (kilogram per cubic meter). The SI unit of density is kg/m3.
Density will be a measure of mass per unit volume. It is an intensive property, meaning that its value does not change depending on the size of the object. In physics, density has been defined as the ratio of the mass of the object to its volume. It has been often defined as mass per unit volume.
In chemistry, density has been defined as the measure of the amount of mass per unit volume of a substance. It has an intensive physical property, meaning that its value does not change depending on the size of the object.
Therefore, The density of a 700 kg object with a volume of 649 m30 is 927 kg/m3. Thus, option A is correct.
This problem is solved using density = mass /volume formula
mass= 700 kg
volume= 649 m³
density is therefore = 700 kg / 649 m³ = 1.079 kg/m³

A sequence of DNA that codes for a protein has a substitution mutation. The new codon codes for the same amino acid as the wild-type DNA. What is the most likely effect of the mutation?
Answer:
There will be no effect of the mutation
Explanation:
Because the mutation codes for the same amino acid, there is no effect

A microbiologist i under optimal is working with two genera of bacteria, A and B, to determine if cells are competent Strain minuteinti condit and DNA fragments that carry the gene for green fluorescent protein is added to each cut,e o each oulturew samples from each treatment are plated to nutrient agar and incubated, after which the plaes a ony the plates from sationary phase demonstrate fluorescent colonies. What can be concluded from the result? A. Both bacteria A and bacteria B cells are competent. B. Competence in bacteria A is constitutively expressed C. Competence in bacteria B is dependent on the phase of growth D. Neither bacteria A nor bacteria B cells are competence
Answer:
The correct option is C: "Competence in bacteria B is dependent on the phase of growth"
Explanation:
Since this set of cells produced fluorescent bacterial colonies, it means it took up the foreign strain of DNA and integrated in into its own plasmid. Since the other strain of cells was not able to present fluorescent bacterial colonies, something might have gone wrong or mishandled while preparing the competent cells.

There is an algal bloom in a bay in a populated area. As the leading marine biologist in the area, what is the most important thing to do, based on scientific evidence about such blooms? warn people about which food is safe to eat develop a strategy to prevent future algal blooms warn people to stay away from the affected area evacuate all wildlife from the bay
The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.
What do you mean by Algal Bloom?
Algal bloom may be defined as the dense layer of tiny green plants that occurs on the surface of lakes and other water bodies when there is an overabundance of nutrients on which the species of algae depends.
Algal bloom grows as a result of Eutrophication. These growing algal species consume all major nutrients like phosphorus and nitrogen and expand their numbers. As a result of this, other organisms of that area feel the scarcity of minerals and nutrients, due to this a large mass of death has occurred. Algal bloom makes the surrounding water oxygen defiecient. So, to prevent these types of activities, it is better to evacuate all living forms and provide them with the other environment.
Therefore, The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.

Which two genotypes in an individual would be expressed as the same phenotype in a diploid organism?
Answer:
The correct answer is - h0m0zygous dominant and heterozygous .
Explanation:
The h0m0zygous dominant which means genotype with two copies of the particular gene, and heterozgyous genotype which means genotype with one copy of dominant allele and one allele recessive allele has the same phenotypic expression in a diploid organism.
In h0m0zygous dominant only dominant phenotype will be expressed and in heterozygous genotype the phenotype will be dominant.
Thus, the correct answer is - h0m0zygous dominant and heterozygous .

A major disturbance that almost caused a total collapse, but that the ecosystem was able to recover from eventually.
The provided question is incomplete, the correct question is attached with the answer:
Answer:
The correct answer is - the grasses which is diseased.
Explanation:
In the event that the grasses were diseased, the environment will recoup itself from this sort of disturbance. On the off chance that the number of inhabitants in snakes and hawks of prey increments so the biological system will recoup itself from this disturbance since snakes are the food of hawks.
So, if the number of inhabitants in snakes increments so more food is accessible for birds of prey as snakes and that is the reason populace of birds of prey likewise increments and the number of inhabitants in snakes is controlled.
An ecosystem is a system where an organism lives collectively and socialise with their surroundings. A robust ecosystem is necessary to keep the control nutrient cycle and food cycle.
A major disturbance from which the ecosystem overcame was when both the grasses and snakes got infected. The explanation for this is:
Increasing the number of snakes affected the size of the grass and decreased the number of rabbits as they were getting eaten by the snakes and hawks.Increasing the number of snakes also increased the number of their prey hawks.Increased hawks population controls the population of snakes and in this way, the biological food cycle will be maintained.Therefore, disease in grasses and snakes caused a major disturbance that almost caused a total collapse, but the ecosystem was able to recover.

What nutrients, or matter, must pass through the cytoplasm to reach the cell structures that make up a cell?
Answer:
The correct answer is - amino acid, sugars and fats molecules are major nutrients.
Explanation:
Cell nutrients come in numerous structures, including amino acids, sugars and fats. So as to provide energy to the cell and provide structures, these particles need to go over the cell membrane, which capacities as a barrier that can be pass through different means like endocytosis, diffusion, facilitated diffusion and many more.
plasma membrane is semi-permeable layer which allows specific molecules and substances to pass through the cell and make celular structure and provide energy.
