Suppose all the alleles on on the left and right chromosomes switched places but kept the same order. Would the organism be different? Why or Why not?
Answer:
No
Explanation:
The chromosome will stay the same organism.
The organism would be same in both homogenous and heterogenous chromosome . Therefore, switching the alleles won't change the organism if order is maintained.
What is chromosome and its type ?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
An organism is said to be homozygous if it has identical genes on both chromosomes. It is referred to as heterozygous if the organism possesses two distinct alleles of the gene.
Therefore, if the alleles switched places but the order remains same then organism will be same too in case of homologus as well as heterologus chromosome.

Explain how meiosis results in UNIQUE cells.
Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.
Meiosis is the process such as:
Meiosis occurs in the reproductive cells of humans. Meiosis transmits genetic information from parent to offspring. Meiosis is the characteristic feature of sexual reproduction. The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.
Thus, meiosis always results in new variations and creates genetic diversity.

Choose two other elements from the periodic table that you predict should react to form something like table salt
Please pleassssss helppp
I give branlistttttt
Answer: Potassium (K) and bromine (Br)
Explanation:
Table salt has the chemical formula of NaCl which is formed by the transsfer of electrons from sodium to chlorine.
As sodium (Na) has 1 valence electron and chlorine(Cl) has 7 valence electrons, one elecron is transferred from sodium (Na) to chlorine (Cl) to form an ionic bond between the two.
Similarly Potassium (K) with 1 valence electron and bromine (Br) with 7 valence electrons, transfer of electron takes place from potassium (K) to Bromine (Br) to form an ionic bond between the two resulting in the formation of salt potassium bromide (KBr).

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes
Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.
What is Algae?Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.
Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.

Make a comics strip of your successful life starting today until 20 years later.
Answer:A comic strip is a sequence of drawings, often cartoon, arranged in interrelated panels to display brief humor or form a narrative, often serialized, with text in balloons and captions. Traditionally, throughout the 20th and into the 21st century, these have been published in newspapers and magazines, with daily horizontal strips printed in black-and-white in newspapers, while Sunday papers offered longer sequences in special color comics sections. With the advent of the internet, online comic strips began to appear as webcomics.
Explanation:
Comic strips are used to tell a story. The three crucial elements of a story are setting, characters, and plot. Comic books evenly mix text and visuals. In comic strips, the evolution of the tale is shown by a sequence of frames.

Predict the most likely effect on cell division for a cell containing DNA with double-strand breaks. Justify your prediction.
Answer:
it may lead to the arrest of the cell division cycle
Explanation:
The presence of DNA double-strand breaks (DBS) during cell division generally leads to the activation of cell cycle 'surveillance' checkpoint mechanisms. The surveillance mechanisms act to ensure the correct functioning of the cell during its division, controlling the order and fidelity of the events during the cell cycle. Some of the most important surveillance mechanisms include spindle assembly checkpoint, proper cell size, replication/integrity of the chromosomes, etc. If surveillance mechanisms detect a problem with the DNA (e.g., a DBS), they will lead to the arrest of the cell division cycle, and the cell will try to either complete DNA replication or repair its damaged DNA. When DNA damage is irreversible, surveillance mechanisms may trigger programmed cell death (apoptosis).
The most likely effect on cell division for a cell containing DNA with double-strand breaks is to arrest the cell division cycle.
What do you mean by Cell division?Cell division may be defined as the process by which cells multiply involving both nuclear and cytoplasmic division.
In between the phases of the cell cycle, there are checkpoints that ensure the correct functioning of cells during the whole process of cell division. These checkpoints analyze all the procedure of the cell and then sends it to the next phase. If a cell containing a double-strand breaks, it may activate the checkpoint surveillance and arrest the cell till all the functions make normal.
Therefore, the most likely effect on cell division for a cell containing DNA with double-strand breaks is to arrest the cell division cycle.
