Using the illustration above, why are the chromosomes in two of the sex cells different from the chromosomes in the parent cell?
A
the chromosomes from another parent cell were introduced
B
crossing over occurred in the chromosome
C
an insertion mutation occurred during replication
D
some of the genes were damaged during replication
Answers
Answer: A the chromosomes from another parent cell were introduced
Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.

The other option is "parent 1: RR; Parent w: rr
Answers
Answer:
Parent 1: Rr, Parent 2 Rr
Explanation:
Possible genotype for RR and rr is Rr
Possible genotypes for RR and Rr are RR and Rr
Because one of the offspring from parent 1 and 2 is rr, we can decide that Rr must be parent 2 because there would need to be one r from each parent.

The three things that can be come out of volcanic eruption are heat and smoke, lava and rock pieces. The surrounding places will seriously affect by the lava eruption from volcanoes.
What are results of volcanoes ?A volcano is a crack in the crust of the earth where eruptions take place. Worldwide, there are around 1500 volcanoes that could be active. When volcanoes erupt they can hurl hot, toxic gases, ash, lava and rock that can cause tragic loss of life and property, especially in heavily inhabited areas.
If there is associated rain, snow, or melting ice, volcanic eruptions can also result in secondary phenomena like floods, landslides, and mudslides. Wildfires can also be started by hot ashes.
With the release of volcanic gases like sulphur dioxide, which has the potential to promote global cooling, and volcanic carbon dioxide, which has the opposite effect, volcanic eruptions can have an impact on climate change.

Answer:
D and E
Explanation:
Because two parents are involved, the rate of reproduction is lower in sexual reproduction, but it is beneficial to have increased genetic diversity in the offspring since the level of adaptations in phenotypes will be higher.
Hope it helped
The statements which accurately support the argument that procreation is advantageous over propagation in many species are given below:
Procreation involves two parents which contribute equally to the offspring's genetics.Procreation involves meiosis and fertilization which leads to increased genetic variation in the offspring.What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
Due to the involvement of two parents, procreation increases the genetic diversity among organisms.
In procreation, clutch size is low but parental care is high. It means that this type of reproduction does not produce a large number of offspring.
Therefore, it is well described above.

Answer:
1. Yes and No. Speaking from the POV in which penguins are better of packed together than spread out since they are all focused on a specific region which is the southern hemisphere at the south pole I don't think spreading them out even when having the same exact species would help them survive since they need one another, but speaking in a different POV where multiple species are put in every cold region then yes it may work and it may also benefit in science fields to help ease the search of species and studies of them as well as the habitat of penguins themselves.
2. Penguins share many adaptations because of the idea of them only living in a cold, freezing region. Like, they spent half their time in water and the other half on land. Added to that, all penguins swim very fast due to webbed legs which helps them in surviving in a 100% water environment since Ice is technically frozen water. And they share many more adaptations all because of the cold region habitat they all share.
( I didn't really understand the 3rd one but Ill give it my own opinion )
3. Different geographical locations as I mentioned in the first question also speaks of how penguins wouldn't really survive much without being with their own species or their own type of penguins if that makes sense, although they are predators sometimes the environment might not give them the needed resources like food, warmth, strong legs to swim. Some baby penguins might grow up weak which would lead to weak physical structure which decreases the rate of survival because of not eating well nor keeping a healthy penguin routine that they usually do on the populated area of penguins in the southern hemisphere. So, weak physical structure leads to penguins not having their capabilities of being the predator in the environment and swimming as fast as others. Different environments and geographical locations may have an effect on this depending on penguin species but that's all I know.

(Your response should be at least 4 sentences.)
PLS I NEED THIS IN LESS THEN 3 MINUTES
Answers
Answer:
This would be sexual reproduction and artificial selection.
The farmer would take the largest pigs to breed so they can both give their genes to their offspring which would then also most likely be large.
This can cause genetic mutations and diseases within the farmer's pigs.
Explanation:
Sexual reproduction because you have 2 organisms in the process of pigs reproducing.
Since the farmer is picking and choosing which animals are breeding with each other, it would be artificial selection.

The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.

How does increasing plant biomass (amount of plants) affect atmospheric CO2?
Answers
Explanation:
How does increasing plant biomass (amount of plants) affect atmospheric CO2?Since there are more plants more carbon dioxide is being removed because plants are carbon reservoirs.
Answer:
Plant tissue (including wood) is composed of about half carbon, all of which comes from carbon dioxide (CO2) in the atmosphere. Photosynthesis rates tend to increase as CO2 levels rise, leading to an increase in dry weight, or biomass, of plants grown under elevated carbon dioxide levels.

Mistakes in making copies of a cell's chromosomes can occur as the cell is dividing. Such mistakes can affect a single gene, or a portion of a chromosome. Which term describes this process?
Answers
Answer:
Mutation
Explanation:
A mutation is any change in the nucleotide sequence of the genome of a particular organism. Mutations may be caused by errors during DNA replication or by exposure to environmental mutagenic factors (e.g., ultraviolet radiation, chemical agents, etc). Mutations can be deleterious, neutral or beneficial depending on the environment. When a beneficial mutation occurs in the germline, it may potentially be inherited and subsequently increase its frequency in the population.

Higher law refers to the law that is deemed as superior above other legislations that are made after. In United States, the US constitution is what considered to be the higher law.
The US constitution was created in 1787. Every single law that was created after that can't violate/cross the law written within constitution. Even until today, every laws proposed by congress need to undergone a "judicial review" where the supreme courts will decide whether that law proposal is violating any part of the constitution.
There are the major characteristics of the Higher law and these are mentioned below:
- Create a strong protection for people's basic right.
- Lay out a set of government responsibilities to protect the people.
- Create a distinct limitation on what the government can't do.
- Can only be changed if it obtain the support of the vast majority of the people.
