match the following terms and definitions

a segment that contains the information for making proteins

A complex molecule containing the genetic code

Answers

Answer:

The terms are not included in the question but their terms are:

Gene- a segment that contains the information for making proteins

DNA- A complex molecule containing the genetic code

Explanation:

All living organisms contains genetic material (containing genes) in their cells. A gene is a segment of DNA that encodes the information needed for the synthesis of certain functional products called PROTEIN. The genes undergo expression i.e. transcription into RNA and translation into protein. This protein is responsible for the phenotype living organisms exhibit.

The genetic material in most organisms is the DNA, which is a complex molecule and one of the two types of nucleic acids containing long polynucleotide chains. The DNA stores the genetic information needed for the expression of genes i.e. genetic code. The information are stored in the four nucleotide bases (Adenine, Guanine, Cytosine and Thymine) that constitutes the DNA.

Answers

Answer:

I've corrected the relevant part in the false statement to make it true. Please see below:

Gymnosperms and angiosperms, which are seed plants, alternate between (2) generations.

The statement is true. It alternates between haploid and diploid stages.

Gymnosperms are non-flowering plants with EXPOSED SEEDS and angiosperms are flowering plants with PROTECTED SEEDS.

This statement is also true. The egg is fertilized inside of the flower.

Sporophytes produce spores for reproduction. In seed plants, the male reproductive structure produces MICROSPORES and the female reproductive structure produces MEGASPORES.

The statement is correct. The male gametophyte will fertilize the female gametophyte, known as the egg, to produce a zygote.

Gametophytes produce GAMETES through the process of MITOSIS.

False. The process of meiosis results in gametes, and not mitosis.

The p53 protein is a transcription factor that regulates a cell's progression through the cell cycle after DNA is damaged by ultraviolet ( UV ) radiation. The p53 pathway is shown in Figure 1.
Please answer this question! I will give brainliest!
Please note: p53 regulating image is for the entire problem, whereas part C image is only for part C.

(a) A skin cell completes one round of the cell cycle. Describe the products.
(b) Based on Figure 1, explain how p53 regulates the cell cycle in the presence of damaged DNA .
(c) Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
(d) Based on Figure 1, explain how a mutation to p53 may lead to an increased risk of cancer.

Answers

Answer:

(a) Since skin cells undergo the process of mitosis, the product of one cell cycle is 2 identical daughter cells.

(b) The levels of p53 protein in the cell will rise in response to DNA damage. This will stop the cycle at one point to give time to the repair machinery to regain stability. As can be seen in the figure, CDK inhibitors have been produced which are responsible for halting the cell cycle.

(c) The S phase (synthesis phase) is when replication of damaged DNA would occur.

(d) p53 responds in one of 3 ways to an event of DNA damage: arresting the cell-cycle, apoptosis (programmed cell death), or repairing the DNA. If there has been a mutation in p53, neither of the three way would take place to prevent more copies of damaged DNA being made. A mutated p53 protein would no longer be able to suppress tumors.

Hope that answers the question, have a great day!

The cell cycle is the process in which a cell undergoes four phases of division to give rise to daughter cells.

(a) The skin cell is a type of somatic cell, which undergoes mitotic division. The products of the cell cycle will be two identical daughter cells.

(b) p53 is a transcription factor, which will halt the replication if any error occurs. CDK inhibitors are produced in the cycle, which regains stability and activates the repair mechanism.

(c) The synthesis phase or S phase of the cell cycle is the site where replication of the DNA occurs. It takes place after the G1 phase.

(d) p53 transcription factor can arrest the cell cycle, cause apoptosis, and repair the cell damage. The mutation in the p53 gene can work in any fashion to prevent more damaged copies of the DNA. The mutation in p53 will lead to tumors.

Were the offspring of this organism uniformmeaning they look the same as each other and the parent, or were they diversemeaning they express a variety of appearances? Explain your answer.

Answers

Answer:

Uniform

Explanation:

Complete question -

The organism reproduce asexually. Were the offspring of this organism uniformmeaning they look the same as each other and the parent, or were they diversemeaning they express a variety of appearances? Explain your answer.

Solution

It is given that the organism is reproducing asexually; hence its entire offspring will have resemblance to their parent as well as among themselves. There is no scope of genetic variation in asexually producing offspring. However when an organism undergo sexual reproduction, there are high chances of it producing offspring with varied characteristics as the parents gamete carry genes of ancestors and allows for various recombination. Unlike sexual reproduction, the organism producing asexually produces similar gametes and hence offspring one generation after the other.

d. Adding a gene for mold resistance to corn DNA

Answers

Answer

D, genetic modification is a technique to change the characteristics of a plant, animal or micro-organism by transferring a piece of DNA from one organism to a different organism.

Explanation:

(mark as brainliest please)

Changes in genetic data lead to gene modification. Adding a gene for mold resistance to corn DNA is an example of genetic modification. option D is the correct answer.

 

What is genetic modification?

Genetic modification is a process in which the genes of an organism are modified. This can be done by base insertion or deletion or by any other environmental factor. Genetic modification can be done artificially. CRISPR-Cas9, gene editing, etc. are some examples.

This is done to get more productivity in crops, to reverse a genetic disease, etc. An example is adding a gene for mold resistance to corn DNA. Due to this gene modification, the corn will produce some proteins that will protect it from mold attack. Other options are not correct for the statement, as there is no change in gene activity.

Hence, the correct option is to add a gene for mold resistance to the corn. Option D is the correct answer.

New genes created by genetic engineering produce brand new proteins called "novel" proteins. All proteins have the potential to trigger allergic reactions under certain conditions. Novel proteins are not recognized by the human immune system. In most cases, these proteins are tested in petri dishes rather than the plant itself.



What information did you include in your answer?



Novel proteins may be beneficial to human health.



Novel proteins may cause allergic reactions.



Additional reactions may occur once the protein is introduced to the plant, which could have negative effects on human health.

Answers

Answer:

Novel proteins may cause allergic reactions. Moreover, protein may also suffer folding when they are introduced into the plant, thereby converting them in potential allergens.

Explanation:

Genome engineering techniques are those procedures used in molecular biology to design genetically modified organisms by altering their genomes.

All proteins have the potential to cause allergic reactions. For example, celiac disease is an autoimmune disorder caused by an allergic reaction to the proteins of cereals; however, only a small fraction of proteins is associated with autoimmune diseases. There are many methods to study the potential of protein allergens, the enzyme-linked immunosorbent assay (ELISA) is currently the technique most widely used for this purpose by detecting antibody-antigen interactions (i.e., interactions between molecules of the immune system and antigen allergens).

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?

Answers

Assuming that producers in an ecosystem have 1,000,000 kilocalories of energy, 100,000 Kilocalories of energy would be available to primary consumers.Producers is the trophic level with the greatest biomass

HOW IS ENERGY TRANSFERRED:In a food chain, energy is being transferred when one organism in a particular trophic level feeds on another organism in a lower trophic level.

The lowest trophic level contains the producers, which are organisms that start the food chain. However, only about 10% of energy is available to the organism in the next trophic level as 90% is lost as heat.

Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.

WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next.

As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.

Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.
