Which group has the smallest dispersal distances
a) Seaweeds
b) Fish
c) Crabs
d) Marine Snails
Answer:
d) Marine Snails
Explanation:
Marine Snails has the smallest dispersal distance because of their slow mobility and stick to one place. These marine snails have very limited mobility when they are adults and spend their majority of lifetimes in a small geographical area. Dispersal distance refers to the distance a species can move from an existing place or population or the parent organism. According to this definition we can say that marine snails have the smallest dispersal distances.

Do it again what is the question about
Answer:
B
Explanation:
A comparison of sexual and asexual reproduction is made by a group of students. Which statements accurately
support the argument that sexual reproduction is advantageous over asexual reproduction in many species? Select
all that apply.
A)
Sexual reproduction leads to greater mutation rate than asexual
reproduction
B)
C)
Sexual reproduction has a greater level of cell division than
asexual reproduction.
Sexual reproduction produces greater numbers of offspring than
asexual reproduction.
Sexual reproduction involves two parents which contribute
equally to the offspring's genetics.
Sexual reproduction involves meiosis and fertilization which
leads to increased genetic variation in the offspring.
D)
E)
Heredity and Reproduction
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.

The other option is "parent 1: RR; Parent w: rr
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.

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.

Title: Does temperature have an effect on growth rate of crystals? what about leaving them covered or uncovered? Does dry air or moist air seem to grow more crystals
Hypothesis:
IF
THEN
BECAUSE
Help pls
Answer:
Temperature also affects the growth of crystals because "the higher the temperature, the warmer the crystal solution will be, and the faster its molecules will move. This movement allows them to evaporate more quickly, leaving particles behind to form into crystals.
Explanation:
A Warm and Light Atmosphere
Warm air temperature aids water evaporation, causing the crystals to grow more quickly. Crystals will still grow in cooler temperatures, but it will take much longer for the water to evaporate. Crystal growth also requires light.

What structures do all organisms have in common in the earliest stages of embryonic development
The early stages of embryonic development begin with fertilization. The process of fertilization is tightly controlled to ensure that only one sperm fuses with one egg. After fertilization, the zygote undergoes cleavage to form the blastula.
The formation of a zygote after fertilization and undifferentiated cell are common features during the earliest stages of embryo development.
In vertebrates, fertilization is the process by which two geminal cells fuse to form a zygote, which will develop into an adult organism.The cells are all in an undifferentiated state during the earliest stages of embryonic development.After this process, the cells begin to differentiate to form a defined structure known as gastrula.In conclusion, the formation of a zygote after fertilization and undifferentiated cell are common features during the earliest stages of embryo development.

this problem?
Answer:
Given that, immunodeficiency could mean having a weak immune system. Which means the person would be prone to diseases. A person with immunodeficiency could be going through a hard time as they would have to make sure to stay healthy and be very health consious. They might also not go out to eat in restaurants due to the lack of cleanliness in the kitchens. If caught any disease they would have a hard time curing which could result to death at an unexpected age.
How does anaphase II differ from anaphase I
Answer:
There's a difference.
Explanation:
Anaphase I involves the separating of chromosomes from the sister chromatids and it all occurs in a diploid cell.
Anaphase II involves the split of the sister chromatids into single chromatids and it all occurs in a haploid cell.

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?
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.

Answer: B,C
Explanation:

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.
