(im failing yall sos) while working on a group project for school, a student asked his group member to check his model of a sect

ion of DNA. which feedback would the student receive? (6A)
the model is accurate because all bases are paired correctly.



the model is accurate because it shows all component of each nucleotide.



the model is inaccurate because the base pairs are incorrect.



the model is inaccurate because it is missing the required bases in DNA.

Please help!!!! very confused pt 2
Schach [20]

Answer:

If the genotype of the parents are <em>Iᵃi </em>and <em>I</em>ᵇ<em>i, </em>then four type of offspring will be produced.The genotype of the offspring are, <em>IᵃIᵇ, Iᵃi,Iᵇi, </em>and <em>ii.</em>

Explanation:

<em>IᵃIᵇ = </em>As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

<em>Iᵃi= </em>In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

<em>Iᵇi= </em>In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

<em>ii= </em>This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.

Prior to the 1600s it was believed that all living things were either plants or animals. Which of these inventions led to the de
hram777 [196]

Explanation:

Microscopes are instruments used for viewing microscopic cellular structures, not visible with the human eye. With an arrangement of lenses, and manipulation of light or electrons, these magnify very small objects. Light microscopy uses light and multiple lenses, while electron microscopes use electrons. These create larger images of objects.

Subcellular components and molecules require the closed system of the cell in order to function with different arrangements and features being key to certain phyla, groups and species; this aided in the reclassification of organisms into the kingdoms and phyla we know today.

Further Explanation:

Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory of abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.

Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified. Their components and molecules require the closed system of the cell in order to function with different arrangements and features being key to certain phyla, groups and species; this aided in the reclassification of organisms into the kingdoms and phyla we know today.
