A cricket has 22 chromosomes in each body cell (somatic). How many chromosomes are in each sex cell (egg or sperm) of a cricket?
Answer:
How many of these chromosomes will be found in an egg cell? All 46 chromosomes. No, sex cells have a half set of chromosomes. 23, one from each pair.
Explanation:
Original DNA strand: ATT GAG CC Mutated DNA strand: ATT GAG CT What type of mutation does the example above demonstrate?
Original DNA strand: ATT TGA GCC
Mutated DNA strand: ATT TGA GAC C
What type of mutation does the example abo w demonstrate?
The examples above demonstrate a substitution mutation.
A substitution mutation is a type of mutation that occurs when one nucleotide in the DNA sequence is replaced by another nucleotide. In the first example, the original DNA strand has the sequence "ATT GAG CC," but in the mutated DNA strand, the nucleotide "C" is replaced with "T" at the third position, resulting in "ATT GAG CT." This single nucleotide substitution is a specific type of substitution mutation known as a missense mutation.
In the second example, the original DNA strand has the sequence "ATT TGA GCC," but in the mutated DNA strand, the nucleotide "C" is replaced with "A" at the sixth position, resulting in "ATT TGA GAC C." Again, this is a substitution mutation where a single nucleotide is replaced by another.
Substitution mutations can have different effects on the resulting protein. In some cases, the change in the DNA sequence may lead to the production of a different amino acid during translation, which can alter the structure and function of the protein. Depending on the specific location and nature of the substitution, it can have varying impacts on the phenotype and may or may not result in a noticeable change in the organism.

Answer:
Net force is 100 N
Explanation:
You will use the formula to find the net force/force.
mass = 0.05 kg
acceleration = 2000 m/s^2
F = m × a
F = 0.05 kg × 2000 m/s^2
F = 100 N (Newtons)

White tailed deer begin their reproductive cycle in the fall. Rising testosterone levels in
male white tailed deer cause them to start their breeding season around the same
time. Offspring are born the following spring and summer.
What is the most likely explanation for the white-tailed deer having a seasonal
breeding cycle instead of a monthly breeding cycle?
The explanation for the white-tailed deer having a seasonal breeding cycle should be that deer provide birth in the spring and summer.
What is seasonal breeding?It is considered to be animal species so it should be successfully mated at the time of specific times of the year. It permits the optimization of survival of young because of factors like food, water availability, etc
So, here deer provide birth in the spring and summer for avoiding the pregnancy at the time of hot summer months.

Genetic modification is a method farmers use so their crops are resistant to disease or cold temperatures. Which of these is a negative consequence of using genetically modified organisms?
Genetic modification increases the extinction rate of the modified organism.
Genetic modification decreases the population size of the modified organism.
Genetic modification increases the carrying capacity of the modified organism.
Genetic modification decreases the genetic variation of the modified organism.
Answer:
Genetic modification decreases the genetic variation of the modified organism.
Explanation:
Genetic modification is widely used in agriculture for increasing productivity and to make crops resistant to diseases but along with advantages there are some disadvantages of genetic modification that involve decreases the genetic variation of the modified organism.
This is so because the DNA or genetic material of the modified organisms will have very less diversity as they have grown with the same process and the DNA among the organisms will become similar to each other.
Hence, the correct answer is "Genetic modification decreases the genetic variation of the modified organism."

Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

Microorganisms also exist in the fossil record, but they’re rarer than other types of fossils. The most common fossils form from hard body parts, such as bones, teeth, and shells. Why do you think these fossils are more common than fossils of other soft tissues or microorganisms?
Answer:
Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
Explanation:
Answer:
When the decomposing process of an organism is taking place, it is breaking apart the nutrients within the organism in order to return it to the Earth in itself. When an organism buried at a quicker pace it cause the decomposing process to last at a longer time, which in term makes the chance of it being better preserved in at the same time. Due the bones of different organisms we are able to analyze the organism that has decomposed, because once that time of decomposition is complete we will be able to see the fossils of the organism and the evaluate the categorization of the specific organism that a scientist is examining.

3. Give one reason why the reaction, ADP + P > ATP + H20, requires energy input.
(Hint: Notice the charges of the molecules in the top figure.)
Answer:
Both ATP and Phosphates have a negative charge. Energy is used so that the electrons do not repel each other.
Explanation:
Phosphates and ATP share the property of having a negative charge. In order to prevent the electrons from repelling one another, energy must be applied.
Why ATP formation need energy?The hydrolysis of ATP to ADP is reversible, just like the vast majority of chemical processes. Through the process of the opposite reaction, ATP can be regenerated from ADP using Pi and ADP. Since the hydrolysis of ATP results in the release of energy, the synthesis of ATP must involve the addition of free energy.
Phosphates and ATP share the property of having a negative charge. In order to prevent the electrons from repelling one another, energy must be applied.
By rupturing and then reforming the bonds that hold its phosphate groups together, ATP is able to effortlessly release and store energy. Because of this property, ATP is an excellent candidate for the role of fundamental source of energy for each and every cell.

When is the most possible time for fertilization if the menstrual cycle is 28 days? Why?
Answer:
You're most fertile about 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.

Yes, I belive in evolution because of how muech the world has changed it's form over they years. To break it down a little more take humans for an example we weren't always like this we didn't have all these citys, buildings, tec, and so on. Back in the days when we still have native tribes and explorers they didn't have a house to sleep in they slept in tents or in carrages but as time evolved so did our minds and our brains thats when cabins started then after that houses then cars, power, and even more, but they had to learn how to do this. They evolved their minds to create they evolved to make it throught bad times they had to evolve along with mother nature her self. we all made it this far thanks to the great mind of evolution adn thats why I believe.
