B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.
Explanation:
Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.

If illegal hunting of oxpeckers increases in 2012 and causes a decrease in oxpecker numbers, what will most likely happen to
rhinoceros populations?
Answers
a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.
Oxpecker numbers are projected to decline as a result of increased unlawful hunting, which will have a negative impact on rhinoceros populations.
The ticks and parasites that live on the skin of rhinoceroses and other large mammals provide the food source for oxpeckers, which are birds. By keeping the animals free of parasites and warning them of imminent danger, they offer an important service.
The number of ticks and other parasites on rhinoceroses may increase if oxpecker populations drop as a result of hunting, which could result in health issues and lower survival rates. In addition, rhinoceroses might be more susceptible to predators and other dangers without oxpeckers to provide warning sounds. So, a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.

"Pitcher plants are carnivorous." Is it true or false?
Answers
Yes, it is true that pitcher plants are carnivorous. Pitcher plants are a type of carnivorous plant that have evolved to obtain essential nutrients from insects and other small organisms.
The answer in True.
These plants typically grow in nutrient-poor soil conditions and have adapted to capture and digest insects as a way to supplement their nutrient intake.
The main feature of pitcher plants is their modified leaves, which form a pitcher-like structure. This structure is filled with a liquid that contains enzymes and other substances that can break down the captured prey. The rim of the pitcher, called the peristome, is slippery, causing insects to fall into the trap. Once trapped, the insects are digested, and the nutrients are absorbed by the plant.
There are several types of pitcher plants, including the North American Sarracenia, the tropical Nepenthes, and the Cephalotus from Australia. Each species has unique adaptations and trapping mechanisms that help them capture different types of prey.
In summary, pitcher plants are indeed carnivorous, as they have adapted to obtain essential nutrients from insects and other small organisms. They do so through their unique pitcher-like structures, which are designed to trap and digest prey. This adaptation allows them to thrive in nutrient-poor soil conditions.
The answer in True.

Which factors changed throughout the experiment? Check all that apply
Answers
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

Congratulations! In vitro fertilization was a success. You and your partner are now waiting for the arrival of your baby. If a gamete from Donor B was used, what is the chance/probability that your baby will have no freckles (rr) AND wavy hair (T'T)? Donor B is heterozygous for the hair trait while you have curly hair (see class notes for curly hair genotype). Below, make your punnett square(s) for this question and be sure to use the correct allele notation for our lecture class. Once you made your punnett square(s) talk with some groups around you (or with Dr. Cline-Brown) to check if you are all on the right track.
Answers
The probability of having a baby with no freckles and wavy hair, given that a gamete from Donor B was used, is 25%.
What is probability?
Based on the information provided, we know that Donor B is heterozygous for the hair trait (T'T) while you have curly hair (TT). We also know that the trait for freckles is recessive (r).
To determine the probability of having a baby with no freckles (rr) and wavy hair (T'T), we need to create a Punnett square using the gametes from Donor B and your partner.
Donor B:
T' T
. .
T' T'T'
T TT
Partner:
T T
. .
T TT
T TT
Combining the gametes, we get the following Punnett square:
T' T
T T'T TT
T T'T TT
From the Punnett square, we can see that there is a 25% chance of having a baby with no freckles (rr) and wavy hair (T'T), as this combination only appears in the bottom left cell of the Punnett square.
Therefore, the probability of having a baby with no freckles and wavy hair, given that a gamete from Donor B was used, is 25%.

https://brainly.com/question/30034780
#SPJ1
Assuming that freckles and wavy/curly hair are determined by different genes, we can consider them independently. Let's first focus on the hair trait.
Donor B is heterozygous for the hair trait, which we can represent as T'T. You have curly hair, which we can represent as TT. Therefore, your genotype for hair is TT.
To determine the probability of your baby having no freckles (rr) and wavy hair (T'T), we need to create a Punnett square for the cross between Donor B and you.
The Punnett square for the hair trait is:
r
T' T
T' T'T' T'T
T T'T TT
Since Donor B is heterozygous for the hair trait, we have two possible gametes: T' and T. Since you have the genotype TT, you can only contribute a T gamete.
Now, let's consider the freckles trait. We don't know your genotype for this trait, so let's assume that you are heterozygous (Rr) and that Donor B is homozygous recessive (rr). This gives us the following Punnett square for the freckles trait:
R r
r rr Rr
r rr Rr
Now, we can combine the Punnett squares for the hair and freckles traits to determine the probability of having a baby with no freckles (rr) and wavy hair (T'T):
r
T' T
T' T'T' T'T
T T'T TT
R r
r rr Rr
r rr Rr
To get the probability of having a baby with no freckles and wavy hair, we need to look at the offspring that are T'T and rr. There are two possible genotypes for these offspring: T'T'rr and TTrr.
Therefore, the probability of having a baby with no freckles and wavy hair is:
P(T'T'rr) + P(TTrr) = (1/4) + (1/4) = 1/2 or 50%
So there is a 50% chance that your baby will have no freckles and wavy hair if a gamete from Donor B was used, assuming that freckles and hair are determined by different genes and that you are heterozygous for the freckles trait.
What is punnett square
The Punnett square consists of a grid with two rows and two columns, representing the possible alleles (versions of a gene) contributed by each parent. The alleles are written along the top and side of the grid, and the boxes in the grid represent the possible genotypes (combination of alleles) of the offspring.
What is heterozygous
Heterozygous refers to having two different alleles (versions) of a particular gene. In other words, a heterozygous individual inherits two different versions of a gene, one from each parent.

you decide to halve the time you spend in the shower each day and to turn off the water while you're brushing your teeth and washing your face at the sink. Evaluate the effect that these actions might have on two different aspects of the water cycle if every person in your neighborhood also performed them
Answers
Answer:
If every person in your neighborhood decided to cut the amount of water they use in half, that would have a tremendous positive effect on the water.
Explanation:
Reducing shower time and turning off water while brushing teeth conserves water, benefiting both water supply by preserving sources and reducing demand on treatment facilities.
By halving the time spent in the shower and turning off the water while brushing teeth and washing faces, individuals in the neighborhood can significantly reduce their water consumption. This would have a positive effect on both the supply and demand aspects of the water cycle. On the supply side, the reduced usage would decrease the strain on local water sources such as rivers, lakes, and underground aquifers. It would contribute to the conservation of these resources, promoting their sustainability and maintaining ecological balance.
On the demand side, the reduced water consumption would alleviate the pressure on wastewater treatment facilities, reducing energy requirements for water treatment and decreasing the discharge of treated water back into the environment. Overall, these actions would promote water conservation, help preserve natural water sources, and contribute to a more sustainable water cycle in the neighborhood.
