Faster growing trees demand for wood can be met by trees that grow faster than average. Genetic engineering has produced trees that can ward off biological attacks, grow more quickly and strongly and creat better wood than trees that are not genetically modified. Do you think this is a good thing? Why or why not?
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.

Which sentence best describes evolution? Populations remain the same over time. Individuals select different food sources due to competition. Inherited characteristics within a population change over time. An individual acquires certain traits during its lifetime.
Answer:
The inherited characteristics within a population change over time.
Explanation:
The evolution is related to the changes in the inherited characteristics over time in the biological population with the successive generation. These are inherited characteristics that are based on genes and passed from generation to generation through the process of offspring during reproduction.
Evolution can occur when the natural selection and the genes drift act together at the same level. The result is that some characteristics in the generation are common and some characteristics are different in this new generation.
Answer:Option C
Explanation:
Evolution can be defined as the change in the inheritable traits over successive generations.
The most preferable characters are selected by natural selection over a period of time. The organism having the desired trait will have more chances of survival as compared to the organism having no variation.
The characters that is inherited in the population changes over time is carried to the offspring.
Hence, the correct answer of this question will be option C.

The diagram shows embryo development of four different animals. How is this evidence used to suggest that life changes over time?
History of Life on Earth
All organisms have the same RNA at the beginning of development, but then the RNA changes over time to create new DNA for the differentiating characteristics.
Even in the early stages of development, these embryos are quite distinct from each other, indicating that life has changed over time to create this variety.
In the early stages of embryonic development, these four vertebrates are quite similar, indicating a possible common ancestor.
Late-stage embryonic development illustrates how, in spite of a common ancestor, each species has acquired differentiating characteristics over time that make each a unique species.

how can blood grouping be used in paternity testing
Answer:
blood grouping can exclude a man from being a child's father.
Explanation:
blood grouping can provide unmistakable evidence that a male is not the father of a child. Since red cell antigens are transmitted as dominant characteristics, a infant can not have a blood group antigen that is not present in either or both parents.

Explain what holds the Solar System together. Give evidence to support your claim (think how).
Answer:
Gravity is what holds the solar system together, not only is it gravity it is the sun's gravity, and since the planets orbit around the sun, it's what keeps the solar system together. Explain how the planets in the solar system formed.
Answer:
GRAVITATIONAL PULL
The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit.
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Explain how it is possible for two parents to produce an offspring that expresses a phenotype not seen in either parent. Use the following terms in your answer: dominant, recessive, meiosis, segregation, recombination, allele, and any other that may apply.
Answer:
A phenotype is what you look like. The parents are showing the dominant phenotype. If we were talking about eye color, the dominant trait is brown eyes. However, the parents might have a recessive gene which is covered by the dominant one. Say they both have Bb genotypes. The capital B is brown and the lower case is blue. Their blue gene is still there, just covered by a brown one. In a punnett square, there is a 25 percent chance a child will have blue eyes (bb) In most cases, the children will end up will brown eyes. Hope that helps!

4. A silent mutation is a change in the DNA that does not change the encoded
and has no phenotypic effect.
Answer:
protein
meiosis
trisomy
amino acid or stop codon
Diagnosing genetic conditions can be difficult because, although scientists have identified genes related to specific diseases, often not enough is known about the disease to determine the exact role of a given gene in the disease. In other cases, perhaps no mutation exists on a known gene for a condition, but a mutation occurs on a related gene that also gives rise to the condition. The human genome is vast, with about 24,000 genes. Scientists do not yet understand the roles and interactions of all these genes in human health and disease.
Meiosis is the process by which germ cells—egg cells in females and sperm cells in males—develop. Meiosis causes germ cells to obtain only half the chromosomes of the person. If the chromosomes fail to separate properly and are shuffled improperly into the chromosomes, an egg cell or sperm cell can have either too few or too many chromosomes. Trisomy 21, or Down syndrome, is a developmental disorder in which three copies of chromosome 21 are passed down from the person's mother and father. The word "trisomy" means that there are three copies of chromosome 21, indicating that one of the germ cells did not undergo meiosis properly. This condition affects about 5,000 babies born each year.
In a silent mutation, one nucleotide base in a protein-coding region gets swapped out for another base. However, the resulting three-nucleotide sequence, or codon, encodes for the same amino acid.
Explanation:
Penn Foster :)
Protein, meiosis, trisomy, amino acid, or stop codon leads to genetic changes.
What is a genetic mutation?Meiosis is the process by which male and female germ cells—egg and sperm cells, respectively—develop. Germ cells only get half of the person's chromosomes during meiosis.
An egg cell or sperm cell may have either too few or too many chromosomes if the chromosomes fail to split correctly and are shuffled wrongly into the chromosomes.
Down syndrome, also known as trisomy 21, is a developmental disease when three copies of chromosome 21 are inherited from the mother and father. When chromosome 21 is found in three copies, this suggests that one of the germ cells did not go through meiosis properly.
Therefore mutation leads to trisomy, change in meiosis, and silent mutation is due to amino acid.

Two sperm fertilizing two different eggs that were released in the same cycle. therefore, option C is correct.
What are fraternal twins?Fraternal twins are also known as dizygotic twins or non-identical twins. They are produced when two different eggs fertilized two different eggs. Fraternal twins may be the same or opposite gender, they look different from each other and their genes are as different as any other siblings.
They are different from identical twins or monozygotic twins. Identical twins have the same kind of genes and their physical appearance is also the same. Twin pregnancies are complex, but fraternal pregnancy has fewer complications.
Fraternal twins are the result of the fertilization of two eggs and two sperm. Therefore option C is correct.
