In Labrador dogsblack fur (B) is dominant over golden fur (b). If you cross two heterozygous parents, what percent of offsprings will have golden fur?
Answers
Answer:
25%
Explanation:
This question involves a single gene coding for fur color in Labrador dogs. The allele for black fur (B) is dominant over the allele for golden fur (b). This means that a heterozygous dog (Bb) will have a black fur.
According to this question, if two heterozygous parents are crossed i.e. Bb × Bb, the following gametes will be produced by each parent: B and b. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Black fur (BB, Bb) = 3/4
Golden fur (bb) = 1/4
Hence, the percentage of offsprings that will have golden fur is 1/4 × 100 = 25%.

According to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.
What is Community?A Community may be defined as a group of individuals belonging to different species living in the same area at a given time.
The individual is the unit of the population, while the population is the unit of evolution. This form of evolution is significantly required in order to construct a community where the different groups of individuals of different species are gathered in such a way that one depends on another.
Therefore, according to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.

c. Photosynthesis uses light energy to convert carbon dioxide and oxygen to glucose and water.
d. Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.
Answers
Answer:- D
Photosynthesis used light energy to convert carbon dioxide and water into glucose and oxygen
The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.
Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.
The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.
Thus, the correct option is statement D.

Answers
Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.
What is Kreb's cycle?Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.
In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.
Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.
