In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BBFF x bbff cross would be expected to be heterozygous for both traits?

Answers

Answer 1

Answer:

100%

Explanation:

This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).

In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:

BBFF - BF, BF, BF, and BF

bbff - bf, bf, bf, bf

Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.

Photosynthesis is illustrated by the diagram.

What is photosynthesis?Photosynthesis is a process through which plants and other organisms transform light energy into chemical energy, which is then released to power the organism's activities through cellular respiration.6CO2 + 6H2O = C6H12O6 + 6O2 Above equation is a typical representation of photosynthesis. This signifies that light energy captured by chlorophyll (implied by the arrow) converts the reactants, six carbon dioxide molecules and six water molecules, into a sugar molecule and six oxygen molecules, the products as shown in the picture provided.

Two characteristics of most plants are a root system and a shoot system. Most of the structures in these systems are common to all plants; however, there are some variations. Which structure can sometimes be found as part of the shoot system? Stems leaves roots flowers

Answers

Answer:

stems, leaves, flowers

Explanation:

There are two parts in the plants  ----

1. the shoot system

2. the root system

Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.

The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.

When scientists discuss the Sixth Extinction, they are referring to which pattern in the rate of extinction?

Answers

Explanation:

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.[3][4][5] The included extinctions span numerous families of plants[6] and animals, including mammals, birds, reptiles, amphibians, fishes and invertebrates. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, or no one has yet discovered their extinction. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates.

Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. Because CO2 produces an acid in water, BTB can indirectly measure how much CO2 is present in a solution. When placed in solutions with neutral pH (little CO2), the solution appears green. In solutions with low pH (high CO2), the solution appears yellow.A teacher performed a demonstration to investigate how photosynthesis and respiration cycle carbon and oxygen. She placed a few drops of BTB in a test tube containing distilled water. Because distilled water has a neutral pH, the solution appeared green. The teacher used a straw to blow into the solution, and the solution turned yellow. She then placed an aquatic plant into the test tube, covered it to keep it air tight, and placed it under a light for 24 hours.What color would the solution in the test tube be after being in the light, and what would it be if it were then placed in the dark for 24 hours, and why?AGreen after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.BYellow after being placed in the light because the plant would release CO2 by photosynthesis; green after being placed in the dark because the plant could not photosynthesize in the dark.CGreen after being placed in the light because the plant would remove CO2 by photosynthesis; green after being placed in the dark because no CO2 would enter the tube since it is air tight.DYellow after being placed in the light because the plant would release CO2 by photosynthesis; yellow after being placed in the dark because no CO2 could leave the tube since it is air tight. sports drinks- $1.75pizza- $2.25 Which allied leader was the only one to head his country at the start and at the end of What type of boundary is above India?
