Analyze the human karyotype and give two examples of pairs of metacentric chromosomes, two examples of telocentric pairs, and two examples of acrocentric pairs.
Answer: The test that is conducted to evaluate and identity the shape,size and number of chromosomes in cells of organism is called the Karyotype.
Metacentic chromosomes are X - shaped chromosomes. They have centromere at the middle, which makes the arms of the chromosomes equal in length. Therefore any type of chromosomes with equal length of arms is said to be Metacentic. Thus chromosomes on position 1,13, 16 , 19 and 20 are examples.
When a pair of chromosomes showed a regular segregation at anaphase of meiosis, they are said to be telocentric. They are type of chromosomes in which the centromere are located at the terminal ends of the chromosomes, with the telemeres extending from theses ends.Hence during segregation, the ends of telocentric chromosomes are orientated towards the poles of the cells. example is the alphabets ''i'' shaped chromosomes in mice and 29 pairs autosomes in Angora goats.
When the centromere is located in such a way that one arm lenght of a chromosomes is longer than the other, then this is called acrocentric. Example is chromosome 21 of down syndrome.others are 13, 14, 15, 22, and Y-chromosomes.

Parent organisms and offspring have what DNA?
Answer:
If the parent reproduces sexually, it's offspring will inherit exactly half of it's DNA. The other half is inherited from the other parent. If the parent reproduces asexually, it's offspring will be a clone (i.e. have the same DNA).
Explanation:
outline the digestion of fats
Answer:
In the small intestine , bile salts emulsify fats. They lower the surface tension of the fats , that is , they reduce the attractive forces between the fat molecules . This causes the fats to break into tiny fat droplets suspend in water , forming an emulsion . Note that this is just a physical break -up , but no chemical digestion of fat molecules has occurred . Emulsification increases the surface area to volume ratio of the fats , speeding up their digestion by lipase.
Emulsified fats are digested by lipase (pancreatic and intesɠintestinal lipases ) to fatty acids and glycerol . Thus the end - products of fat digestion are fatty acids and glycerol .

A pot holds 324 milliliters of water. How many liters will 19 pots hold?
Answer:
6156 milliliters of water or 6.156 liters of water. All you have to do is go like 324 X 19 = ? Then you just multiply it out and it will look like 324 X 19 = 6156 Then you divide 6156 by 1000 which will look like this 6156 / 1000 = ? Then you work it out and it will look like this once you are done 6156 / 1000 = 6.156

Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain
THXSSS PLEASE HELP AND HURRY
Answer:
Explanation:
Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.
When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.
Answer:
Sea breeze.
This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface
Explanation:
Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.
Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.
During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze
Explain why the Panama disease has such a negative effect on Gros bananas
Answer:
Fusarium wilt of banana, popularly known as Panama disease, is a lethal fungal disease caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc). ... The fungus enters the plant through the roots and colonizes the xylem vessels thereby blocking the flow of water and nutrients.
Explanation:
hope it helps:D
Panama disease is a fungal pathogen that was discovered on an Australian banana farm in 1876. The disease causes fusarium wilt in banana plants, eventually killing the crop.
What is Panama disease?Panama disease, also known as banana wilt, is a devastating banana disease caused by the soil-inhabiting fungus Fusarium oxysporum forma specialis cubense.

some of the advantages of inorganic farming.
Answer:
With the use of pesticides, farming can be faster and it also detracts insects and weeds
Answer:
One advantage inorganic fertilizers offer is that they are fast acting. These nutrient-rich salts dissolve quickly and are immediately available to the plants depending on them to provide essential nourishment in the form of nitrogen, phosphorus and potassium.Organic fertilizers usually contain plant nutrients in low concentrations. Since many chemical/inorganic fertilizers are concentrated and very soluble, it's easier to apply too much and damage your plants. Fresh, non-composted manure can damage your plants as well, because some manure contains harmful amounts of salts

D) organisms are made up of large number of cells
The feature of cell theory that is best demonstrated in the image is organisms are made up of a large number of cells. Thus, the correct option for this question is D.
What is Cell theory?The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.It is the basic structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.
According to the three assumptions given above, the one which is best demonstrated by the image is that Organisms are made up of a large number of cells.

Where are metamorphic rocks likely to form?
Answer: deep in planets crust
Explanation:
Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

Which scenario causes gene flow
Answer: Migration is one way that genes are transferred from one population to another.
Explanation: Gene flow is caused by a significant change in the population of individuals due to the addition of other individuals whose alleles are slightly different from those of the existing individuals
Answer:
Introgression refers to gene flow from another taxon. While low levels of gene flow between species are not uncommon, it is a serious issue when an introduced invasive species hybridizes with a native species and overwhelms its genetic constitution (genetic swamping). This is a major threat in canids, ducks, fish and plants. For example, exotic rainbow trout introduced into the habitats of native cutthroat trout in the Western United States led to hybrid swarms that eventually overwhelmed the local species. Introgression is readily detected by molecular genetic and genomic methods.
