Answer:
Meiosis.
Explanation:
This is because meiosis is a type of cell division in that occur in sexual producing organism in which the chromosome number is reduce to half and produce for gamete. The diploid patent chromosome are reduced to half or haploid. This is the cell diving that produced sexual gamete i.e sperm and egg. In the case of fruit fly with 8 chromosomes and it is reduced to 4 is as a result of it undergoing meiosis.
What features of larkeys affect their survival?
What traits helped larkeys survive when they moved to the prairie environment?
What traits helped larkeys survive when they moved to the forest environments?
What factors in the environment affected the survival of larkeys?
Answer:
el sapo
Explanation:
Spotted larkeys were difficult for bobcats to see in the forest because they mixed in with the dappled light coming through the trees. Larkeys with short legs might hide from the bobcats by ducking behind shrubs. Bobcats could easily notice striped larkey in the dense jungle.
What are the features of larkeys to affect their survival?Striped larkeys were tougher for the coyotes to locate in the prairie because they mixed in with the prairie grass.
The ability to sprint quicker gave long-legged larkeys a better chance of eluding the coyotes. However, because of the surrounding grass, spotted larkeys were simple for the coyotes to spot.
Therefore, The prairie larkey's short legs and spots and the forest larkey's long legs and stripes both failed to help them withstand the pressure.

Use complete sentences or list form in order to describe the steps of replication. You must
use the following words and underline them:
Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand
Answer:
Please find the description below
Explanation:
DNA replication involves the duplication of the DNA molecule in the NUCLEUS to yield two identical copies. It involves the following steps:
- DNA molecule (double stranded) is unwound or separated into a replication fork by DNA helicase.
- The DNA, which now comprises of two single strands i.e. one strand that runs from the 3'-5' called LEADING STRAND and other strand that runs from '-3' called LAGGING STRAND.
- An enzyme called DNA POLYMERASE attaches to the DNA and adds nucleotide in a bidirectional pattern i.e. adds nucleotide to the leading strand in a 5'-3' direction, then adds short pieces of DNA called OKAZAKI FRAGMENTS to the lagging strand.
- The synthesis of nucleotides by DNA polymerase follows the COMPLEMENTARY BASE PAIRING rule i.e. A-T, G-C.
- Another enzyme called DNA LIGASE joins the okazaki fragments together into a whole DNA.
At the end of replication process, two identical copies of DNA is produced, with each containing one old strand and one new complementary strand.

13. With the massive amount of plant life, ample rainfall and favorable temperatures, you might think
that tropical rainforests would be large net producers of oxygen, and yet surprisingly, they are not! With
your knowledge of photosynthesis and cellular respiration, can you explain why this might be true?
Think about what happens when a leaf drops or fruit from a tree is eaten.
Answer:
Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.
Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.
After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.
Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.
Food poisoning is typically the result of which type of pathogen, which can usually be treated with antibiotics?
Virus
Parasite
Fungi
Bacteria
Answer:
Bacteria
Explanation:
There are four general types of pathogens. Bacteria, such as E. coli are living things that grown on protein-rich sources such as foods. They can be killed with high heat, or treated with antibiotics Viruses are non-living and cannot be treated with antibiotics. Fungi have their own cell membranes and organelles, which makes antibiotics harder to use. Parasites are living organisms that live and feed off of their host.

2. Many people believe that a mutation will always result in the formation of a deadly tumor, or the development of a major body defect.
Explain why this is incorrect.
. There are multiple types of mutations in DNA. ______________mutations occur when a single base is changed to a different base pair.______________mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation. __________mutations are also considered frameshift mutations, and occur when one or more extra bases are added to a segment of DNA.
Answer:
substitution; deletion; insertion
Explanation:
Mutations are genetic changes generally associated with deleterious effects. However, mutations may not have an effect on the phenotype of the organism and even, eventually, they are beneficial. For example, a missense substitution occurs when a nucleotide is replaced by another that changes the encoded amino acid, which may have deleterious or beneficial effects (depending on the new protein and its effects on the fitness of the individual in a particular environment), while a silent substitution does not modify the encoded amino acid and thereby it has no effect on the phenotype. On the other hand, a frameshift mutation is a mutation that involves the insertion or deletion of a nucleotide base, thereby irreversibly altering the Open Reading Frame (ORF) of the protein.

One result of meiosis is the formation of gametes
A. True
B. False
Answer:
T
Explanation:
It is true that the result of meiosis is the formation of gametes. Therefore, option A is correct.
What is meiosis?a unique method of cell division in which the amount of DNA received by each daughter cell is halved compared to the parent cell. In mammals, meiosis takes place during the development of egg and sperm cells.
Since meiosis involves two rounds of cell division, a beginning cell can generate four gametes (eggs or sperm). Cells move through prophase, metaphase, anaphase, and telophase with each round of division.
Chromosome reduction, or meiosis, is the process that enables the generation of haploid germ cells required for sexual reproduction. Meiosis also plays a crucial function in promoting genetic variety and making it easier for recombination to correct genetic flaws. Hence, option A is correct.

Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
The density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.
What is Density?Density may be defined as a type of physical quantity that measures the degree of compactness of a substance. It may also be characterized as the substance's mass per unit of volume. The symbol most often used for density is ρ (row).
According to the context of this question,
The mass of a glass marble = 13 g.
The volume of a glass marble = 5 cm3.
The formula for calculating density is as follows:
Density = Mass/volume.Density = 13 g/5 cm3 = 2.6 g/cm3.
Therefore, the density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.

Which of the following statements are true about hydrogen bonds? (More than one)
A.) A hydrogen bond is stronger than a covelent bond.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on
another water molecule is an example,
D.) A hydrogen bond is stronger than an ionice bond.
Answer:B,C
Explanation: covalent and ionic bonds hold molecules together. It is the polarity of covalent bonds that give rise to hydrogen bonding. As in the water example: the more electronegative O attracts electrons slightly more than the hydrogens, so the O has a fractional negative charge, the Hs a slight positive charge. The O of one molecule and the H of another are held together by this charge difference.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on another water molecule is an example,
Hydrogen bonds exists between molecules in which hydrogen is bonded to a high electronegative atom such as nitrogen, chlorine, fluorine, sulphur etc.
Hydrogen bonds are strong intermolecular interactions. They are responsible for the high boiling and melting points of some polar substances such as water.
However, hydrogen bonds are not as strong as covalent or ionic bonds.

Diffusion of nutrients across a cell membrane can be called a form of Multiple Choice bulk transport. exocytosis. osmosis. active transport. passive transport.
Answer:
passive transport
Explanation:
Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.
Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.
xperimenters found that in rats, a certain type of cell will fire when the animal is in a specific location and not when it is in another location. This type of cell is referred to as a _____ cell.
Answer:
hippocampal place
Explanation:
A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.
Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.
The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.
Hence, the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.
