Answer:
Yes
Explanation:
The pedigree chart would go as far back as it is needed to which would show who has a certain eye color and who would get a certain trait.
Eye color trait is a trait determined by polygenic inheritance using a pedigree chart would work to trace this trait in family.
What is pedigree chart?A pedigree chart is a diagram that depicts the occurrence and appearance of phenotypes of a specific gene or organism and its ancestors from generation to generation, most commonly in humans, show dogs, and race horses.
Pedigree analysis is used to determine whether the inheritance mode is recessive, dominant, partial dominant, autosomal, or mitochondrial.
Furthermore, it determines the likelihood of an individual or offspring being affected in the given cross.
We can determine genotypes, identify phenotypes, and predict how a trait will be passed down in the future by analyzing a pedigree.
A pedigree's information can be used to determine how certain alleles are inherited: whether they are dominant, recessive, or autosomal.
Thus, it is sure that using a pedigree chart would work to trace this trait in family.

A student drew this model to show the flow of convection currents
on Earth.
Part A
Is the model accurate? Explain your answer.
Answer:
Yes the model is correct
Explanation:
Transfer of heat energy takes place usually any of these three processes namely; Conduction, Convection and Radiation. In conduction, transfer of heat energy takes place by microscopic collisions of particles within a body. In radiation, heat, light and energy through any source is sent out from something and moves through space without a material medium of propagation. In Convection, heat transfer happens because of the movement of the bulk of molecules within fluids.
We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another.
The equator is the part on Earth that is nearest to the sun hence it receives much heat. As a result of this, the air near the equator rises upwards as it becomes less dense and later spreads out and again descends towards the equator. This process is responsible for the continual circulation of air which is called wind. It is due to the process of atmospheric convection currents that the clouds are kept aloft.
From the foregoing, the model shown in the image has been validated as a correct model of convection current in nature.
Answer:The model accurately shows convection. However, these large convection currents would occur only if Earth did not rotate. Because Earth rotates, smaller convection cells form.

Why is sustainable development concerned with the needs of future generations?
Sustainable development is concerned with the needs of future generations because Earth's natural resources are
_________.
Answer:
Sustainable development is defined as the principle to meet present need without affecting future generation needs.
Sustainable development is much concerned with the future needs because humans are utilizings the natural resources of the Earth in order to fulfil present needs. But the natural resources of the Earth are non-renewable and will take hundreds or thousands of year to form again, so it is possible that our future generation will unable to consume those natural resources.
Even natural resources cannot be replaced by other resources, example: carbon-based fossil fuel.
Hence, people consuming natural resources in large quantity which can affect future generation needs, as natural resources are non-renewable sources of energy.

provides the master instructions for the cell
joins sister chromatids
codes for a specific trait
Answer:
D.
Explanation:
..
The part labelled B is gene which codes for a specific trait. So, the correct option is (D).
What are Genes?Genes are defined as the basic unit of heredity passed from parent to child that are composed of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.
The main function of genes is to code for a specific trait where every individual on this earth is different from each other. The traits that make individuals alike are the genes they carry.
Traits like eye color, height, ear size, height are controlled by genes where as such characters like fur color, flower size, flower color are also controlled by genes. The characteristics responsible for what a person is like are borne by genes.
Thus, the part labelled B is gene which codes for a specific trait. So, the correct option is (D).

Discuss, why is rubisco the key enzyme for the production of worlds food
Answer:
Rubisco is the major enzyme used to catalyse the carbon fixation step during the Calvin cycle in photosynthesis.
During carbon fixation, RUBP undergoes a redox reaction with CO2 to form 3-phosphoglycerate (a 3 carbon compound). 3-phosphoglycerate then undergoes phosphorylation by ATP and reduction by NADPH to form glycerate 3 phosphate molecules (main product), ADP and NADP+ molecules (by product).
Some Glycerate 3 phosphate produced are used to regenerate RUBP for the Calvin cycle to continue while the rest of the Glycerate 3 Phosphate is used to synthesise monosaccharides like glucose.
Without Rubisco, carbon fixation cannot occur and RUBP will not be able to combine with C02 to form a 6 carbon unstable intermediate the breaks down to form 3-phosphoglycerate and eventually undergoing more reactions to form glycerate 3 phosphate which is the basic product of photosynthesis used to synthesise glucose and eventually starch which serves as the world's food.
