Answer:
The correct answer is: translocation.
Explanation:
When a chromosome breaks, there are many ways in which this can affect the integrity of the genes, as it can cause the deletion of one or several parts of the DNA. Other abnormalities include duplication and inversion of the genes.
When one fragment of the DNA breaks and joins a nonhomologous chromosome, the event happening is a translocation. There are two types of chromosomal translocations:
reciprocal translocations, in which the involved chromosomes exchange segments with one another.Robertsonian translocations, in which an entire chromosome joins another chromosome's centromere.Depending on the type of translocation and the amount and nature of the genes, this abnormality can affect individuals in different degrees.
Aneuploidies, on the other hand, are not related to the integrity of the chromosomes but rather the number of chromosomes. While euploidy refers to a total of 46 chromosomes in humans, aneuploidy describes individuals with more or fewer chromosomes.
All of these anomalies can be identified with a karyotype.
Answer:
Translocation
The large object in the picture above is a single bacteria cell. The many small structures attached to it are viruses called
bacteriophages which are attaching to the receptor sites on the bacteria cell. Which of the following is one important
difference between a virus and a bacteria cell?
Answer Options:
a. a virus is much larger in size than a bacterial cell
b. a virus always causes more severe disease than a bacterial cell
c. a virus can never reproduce on its own, but a bacterial cell can
d. a virus does not contain genetic material, but a bacterial cell does
Answer:
c. a virus can never reproduce on its own, but a bacterial cell can
Explanation:
A virus is not cellular, and is significantly smaller than bacterial cells. Because they aren't cellular, to reproduce, viruses have to infect other cells. Inside the cell, they hijack the cell's machinery to allow their genome to be replicated and new viral particles to form. This is how viruses reproduce. Bacteria reproduce by asexual reproduction.
in what two ways does sun light increase the rate of transpiration
Answer:
mark as brainlliest
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises
58. What do you think would happen if a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles
Answer:
Molecules or proteins will not be transported within the cells from organelles to organelles
Explanation:
If a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles, proteins will not be transported within the cell from one organelles to another because clathrin is a protein that lead to the formation of coated vessicles and these coated vessicles play a major role in vessicular transport by allowing the transport of proteins or molecules with the cells from organelles to organelles like organelles in the post-Golgi network connecting the trans-Golgi network endosomes and also cell membrane and lysosomes.

What is offspring grows?"Offspring grows" is a phrase commonly used to refer to the development of a fetus during pregnancy.
It means that the embryo, which is the early stage of development of the fertilized egg, undergoes a series of cellular divisions and differentiation processes, eventually forming a fully-formed baby.
The growth of the offspring is a complex and highly regulated process that involves many different biological systems and processes, including the placenta, umbilical cord, and various hormones and signaling molecules.
The growth and development of the offspring is a critical aspect of reproduction, and is essential for the continuation of the species.

If an ER signal sequence were added to its N-terminus, which structure would the engineered protein adopt
Answer:
The correct answer would be - structure with both N- terminal and C-terminal in the lumen side.
Explanation:
In eukaryotic cells, the cytosol is the site where protein synthesis takes place which is transported to the endoplasmic reticulum. The protein then moves to the endomembrane vesicle pathway from the endoplasmic reticulum. The transport of the proteins to the different organelles takes place from there as they destined and ultimately secreted from the cell.
In ER such proteins that contain ER signals at the N terminal of the protein are move into the lumen of the endoplasmic reticulum. So, both end N- terminal and C-terminal of the protein ae in the side of the ER lumen

A group of scientists predicts that Earth’s oceans will be able to take up more carbon dioxide as atmospheric carbon dioxide levels increase and the atmosphere warms. Which of these statements about the solubility of gases in ocean water would lead you to question this prediction?
a Solubility decreases with an increase in salinity.
b Solubility decreases with an increase in salinity.
c Solubility decreases with an increase in temperature.
d Solubility decreases with an increase in temperature.
Answer:
b
Explanation:
The solubility of gases in the ocean water should result into decrease in solubility that increases salinity.
What is the solubility of gases?The solubility of a gas should be in the liquid and that should be directly proportional with respect to the partial pressure that should be presented above the surface of the liquid.
Here the henry law should be applied that represent the partial pressure that above the solution also it should be proportional to the fraction of the mole of the gas.
Therefore, the option b is correct.

Can you guys help me with this?
Answer:
The law of segregation states that genes have alternative forms, or alleles. In a diploid organism, the two alleles of a gene separate during meiosis and gamete formation; each sperm or egg carries only one allele of each pair. This law explains the 3:1 ratio of the F2 phenotype observed when monohybrids self-pollinate. Each organism inherits one allele for each gene from the parent. In heterozygous individuals, the two alleles are different, and expression of the dominant allele masks the phenotypic effect of the recessive allele. In hom0zygous individuals, the two alleles are identical.
The law of independent assortment states that the pair of alleles for a given gene segregates into gametes independently of the pair of alleles for any other gene. This law explains the 9:3:3:1 ratio of the F2 phenotypes in a cross between dihybrids.
Explanation:
The law of segregation explains that, during gamete formation, each gamete receives just one copy of the gene (allele) which is random. Therefore, if we have two heterozygotes (Aa), the possible genotypes are AA, aa, Aa and Aa. Therefore, the ratio of the dominant phenotype to the recessive is 3:1.
The law of independent assortment explains that the alleles of different genes are inherited independently of one another. That explains the 9:3:3:1 phenotype ratio when crossing two individuals heterozygous at two different genes

Jon always keeps his bread in the cabinet, in the dark. Recently, his bread has been getting moldy rather quickly and needed to be thrown out. For an experiment, Jon puts two slices of the same brand of bread in the cabinet, in the fridge, in the sunlight (on the counter), and in the freezer. Jon leaves the bread in there for two months and checks it once every day. At the end of his experiment, Jon will look at all his data and compare to see which method keeps his bread fresh the longest.

Independent variable is the variable that is manipulated or changed by the experimenter in an experiment. In this case, the independent variable is METHOD of PRESERVING BREAD or LOCATION OF KEEPING BREAD.
Dependent variable is the variable that is being measured in the experiment. The dependent variable responds to the changes made to the independent variable. In this case, How long the bread stays fresh is the dependent variable.
Constants are variables that the experimenter intentionally keeps unchanged throughout the experiment in order not to influence the result. In this experiment, the constants are: Same slice of bread (2 slices), same brand of bread, same amount of time (2 months).
Control group is the group that does not receive experimental treatment. The control group of this experiment will be the BREAD HE KEEPS IN THE CABINET.
Data type can either be quantitative or qualitative. The data type in this experiment is QUANTITATIVE because it involves the use of counts and numbers, which is time in this case.

If you put a protist into the same three environments, which environment would you expect its contractile vacuole to be most active
Answer: The completed part include the three environment, Hypertonic, isotonic and hypotonic.
The contractile vacuole will be most active in hypotonic environment.
Explanation:
The protist's contractile vacuole will be most active in hypotonic environment because it has lower concentration of solutes outside the cell than other solution which have salt particles which will allow water to constantly entering the cell through osmosis but the protist will counter this by it's contractile vacuole which let out water . The protist contractile vacuole will not hypertonic environment because it will cause the cell to shrink and lose water.
