What are the three types of homologies and the definitions?

Answers

Answer 1

Answer:

hope this helps..

Explanation:

Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. ... Scientists have recently been paying renewed attention to the homology question.

Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.

A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.

Answers

Answer:

If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.

Explanation:

Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic celldiploid— is reduced by half, that is, haploid cells are obtained.

A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.

This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.

What two basic geologic processes contributed to the formation of folded mountain ranges like in Glacier National Park?

B. Faulting of sedimentary rock and erosion.

C. Volcanic ash buildup and faulting of rocks.

D. Folding and breaking of sedimentary rocks and erosion.

Answers

Answer:

D. Folding and breaking of sedimentary rocks and erosion.

The two basic geologic processes that contributes to the formation of folded mountain ranges are ; ( D ) Folding and breaking of sedimentary rocks and erosion

Folded mountains are formed by the collision of two or tectonic plates, the movement and collision is mostly caused by massive erosion.

Tectonic plates are formed by the breaking down of the earth's outermost layer into large rock slabs which lies on a molten layer of rock these large slabs are components/make up the  sedimentary rocks

Therefore the folding and breaking of sedimentary rocks caused by massive erosion leads to the formation of folded mountain ranges.

Hence we can conclude that The two basic geologic processes that contributes to the formation of folded mountain ranges are ; Folding and breaking of sedimentary rocks and erosion

When a doctor needs to give someone a medication intravenously (through a vein), they dilute that medicine in a saline solution (salty water). Why would it be a bad idea for a doctor to mix the medicine with plain water? (Hint: Osmosis is the answer, but you’ll need to explain why.)

Answers

Answer:

it is because the blood cells will have too much water in them and they will burst.

Explanation:

there will be less salt inside the cells so all the water will enter the cells. if there is also salt present outside of the cell then the water and the electrolites(salt) will equalize between the inside and the outside of the cell.

Answers

The trend in the corn productivity shows an increase from the year 1988 to 2008.

This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

Explanation:

The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?

Answers

Answer:

The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.

Explanation:

How much is the pressure of the atmosphere?

Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).

Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

Which represents the cross between parent plants if one is heterzygous and has yellow-colored pods and the other is homzygous and has green-colored pods?
Yy ´ yy
YY ´ yy
Yy ´ Yy
yy ´ yy

Answers

Answer:

Its the first one

Yy is yellow (dominant) and heterozygous

yy is green (recessive)

with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green).  There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy

The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods -  Yy yy

Heterozygous genotype:The presence of two different alleles at a particular gene locus.A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.Y for yellow and y for green then the heterozygous parent would be - Yy with yellow phenotype

Purebred genotype:

consists of gene pairs with genes that are the same allele typealso called the hozygousY for yellow and y for green then the hemzygous parent would be - yy with green phenotype

Thus, the cross would be -  Yy yy

Which of the following correctly describes the function of the cell wall?


The cell wall provides rigid support and protection for the cell.


The cell wall is a network of fibers inside the cell that gives the cell its shape.


The cell wall is a barrier that allows certain substances into and out of the cell.


The cell wall is a series of folded membranes that produces and distributes proteins in the cell.

Answers

the cell wall provides rigid support and protection for the cell

The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.

What is a cell wall?

A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.

The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.

The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.

The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.

Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.

The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.

Therefore, the correct option is A.

Answers

Answer:

A. Cell theory.

Explanation:

The image above shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports a scientific theory known as cell theory with respect to cell division.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cell theory states that cell is the basic unit of life, all living organisms are made up of one or more cells and they typically arise from existing cells i.e pre-existing cells give rise to new ones through the process of cell division.

From the image of the salamander's skin cell, we can see that it comprises of many cells and are these look very much alike, meaning they are from pre-existing cells.
