Which of the following would be an example of an R-selected species?
Answers
An example of an R-selected species would be one that produces a large number of progeny with small size. So, the correct option is C.
R-selected species are characterized by their reproductive strategy, which focuses on producing a large number of offspring with relatively small size. These species prioritize quantity over quality when it comes to offspring production.
Option ''Large number of progeny with small size'' represents an example of an R-selected species. These species typically have a high reproductive rate and invest minimal resources in individual offspring. By producing a large number of progeny, they increase the chances of survival and successful reproduction in unpredictable or unstable environments.
In contrast, options A) Small number of progeny with small size and B) Small number of progeny with large size represent strategies more commonly associated with K-selected species. K-selected species prioritize quality over quantity, producing fewer offspring but providing them with greater parental investment and resources, resulting in larger size and higher survival rates.Option D) Large number of progeny with large size is less commonly observed in nature and does not align with the reproductive strategy of either R-selected or K-selected species.Therefore, the correct option is C.

Which biomolecule is represented in this example?
Answers
Answer: The biomolecule is a protein (more exactly, an enzyme) called tyrosinase.
Explanation:
First, a biomolecule is a molecule present in living organisms, we usually can separate them into 4 groups:
Carbohydrates, lipids, proteins, and nucleic acids.
Ok, albinism is the lack of melanin pigment (and the incapacity of producing it)
The first step to synthesize melanin is the conversion of tyrosine to dihydroxyphenylalanine, catalyzed by an enzyme called tyrosinase, then the lack of the biomolecule causes albinism.
Then here we are talking about an enzyme, and enzymes are proteins that work as biocatalysts.
Then the biomolecule represented in this example is a protein.

A paleontologist identified two distinct species of mollusks in the fossil record of a region. In the layer below a mass extinction that devastated the region, the paleontologist observed that shells of species A was present in small numbers over a widespread area whereas species B was abundant and found in a few restricted areas. Which of the following predictions about the fossil record in the layer above the mass extinction is the MOST likely to be supported by further excavations?
a. Species A survived because of its widespread range including some areas that were not as affected by mass extinction.
b. Species A survived because the low number of individuals meant that there was less competition for resources.
c. Species B survived because it was the more abundant and more individuals survived.
d. Species B survived because the population was concentrated in a few areas and had a higher chance of survival.
Answers
Answer:
a. Species A survived because of its widespread range including some areas that were not as affected by mass extinction.
Explanation:
The species distribution might confer extinction resistance during massive extinction events. One of the most important reasons for a species -or any other taxonomic group- to survive massive extinction is its wide distribution area.
The broad geographical range of a group -as Species A in the example- enhances the survival chances during mass extinctions. When the event occurs, it severely affects most individuals of a certain area. If the species is restricted to that area, then the species will probably disappear, no matter the number of individuals living there.
But if the species is widely distributed, there are more survival chances. The extinction event will only affect a few regions, but not all of them, meaning that some of the individuals of the species will be able to survive.
Probably as only a few individuals of species A got to survive, they must have suffered the effects of genetic drift after the disaster, causing a reduction in genetic variability.
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%.

#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.

Answers
\({\huge{\bold{\hookrightarrow{\blue{\mathfrak{Answer}}}}}}\)
______________________________________
Color blindness is an X-linked recessive trait, meaning that the gene for color blindness is located on the X chromosome. Because males have only one X chromosome, if they inherit the color blindness gene from their mother, they will be colorblind. Females need to inherit two copies of the gene to be colorblind, one from each parent. If they inherit only one copy, they will be carriers of the trait but will not be colorblind themselves.
Color blindness is inherited through the X chromosome, making it more common in males due to their XY genetic makeup.
Color blindness, also known as color vision deficiency, is typically an inherited condition that affects the perception of colors. The inheritance of color blindness in humans is linked to the X chromosome, making it more common in males.The genes responsible for color vision are located on the X chromosome. Since males have one X chromosome and one Y chromosome, while females have two X chromosomes, the inheritance pattern differs between the sexes.In most cases, color blindness is caused by a recessive gene. If a male inherits a single copy of the recessive gene from his mother, he will have a higher likelihood of being color blind because he lacks a second X chromosome to counteract the effect of the gene. Females, on the other hand, require two copies of the recessive gene (one from each parent) to develop color blindness.Therefore, males are more likely to be affected by color blindness, while females tend to be carriers of the gene without experiencing color vision deficiencies themselves.In conclusion, color blindness is inherited in a manner that is influenced by the presence of the recessive gene on the X chromosome, leading to a higher prevalence among males.For more questions on Color blindness

What is the atomic number of an element with 12 protons, 10 neutrons and 12 electrons?
Answers
Answer:
12 protons, 12 neutrons, 10 electrons
This is a magnesium Ion. There are 12 protons from the magnesium atom. There are 10 electrons because 12-2 = 10. There are 12 neutrons because 24-12 = 12.
Explanation:
The atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that element.
In above question following details are mentioned:-
The number of proton is give by 12
The number of neutrons is given by 10
Then number of electrons is given by 12
From above data we can conclude that this is a magnesium ion.
Since, we know that atomic number is always equal to number of protons.
Here we can see that the number of protons is 12 so atomic number is always equal to 12.
So, we can say that atomic number of magnesium is 12
Therefore, the atomic number or nuclear charge number of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number or the number of protons found in the nucleus for every atom of that element.
