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:
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.

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.learn more about Photosynthesis here:

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.
