A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous
Answer:
The correct answer is -
A) BbTt x bbTt
B) .5^4 or 1/16 or 0.0625
Explanation:
As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.
For Branchydactylus and For tasting : man and women will be heterogeneous.
Hence,
The Genotype of man = BbTt
The Genotype of wife = bbTt
b. Answer = 0.0625
For Branchydactylus:
Bb X bb
Possible genotypes:
B b
b Bb( Brachydactylus) bb(normal)
b Bb (Brachydactylus) bb (normal)
The probability of a single child being Branchydactylus = 2/4 = 0.5
So, Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

poison dart frog
sloth
strangler fig
fungus fruit bat
A. To recycle molecular building blocks
a
B. To break down photons
C. To gather green light
O D. To convert light energy into chemical energy
Answer:
OptionA because decomposers are associated
Explanation:
The role of the fungus in the food web shown is to recycle molecular building blocks. The correct option is A.
What is food web?A food web is a diagram that depicts the interconnection of various organisms in an ecosystem via the exchange of energy and nutrients.
The food web is made up of several interconnected food chains that represent the flow of energy from one organism to the next.
Fungi are decomposers that play an important role in breaking down organic matter and recycling nutrients in many ecosystems.
The fungus in the food web is most likely breaking down dead plant or animal matter, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil.
These nutrients are then absorbed by plants, which are then consumed by herbivores such as the coati and sloth.
Thus, the correct option is A.

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices
Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

The graph shows the supply and consumption of forests when the
consumption rate and population growth rate are both low.
When does consumption begin to surpass supply?
Answer:
In about 625years
Explanation:
According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.
Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.
Answer:
In about 625 years
Explanation:
Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph

2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.
3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.
4) Surprisingly, rain forest soil is very poor.
5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.
6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.
