Which of the following are shown in karyotypes?
a
sex chromosomes
b
homologous chromosomes
c
autosomes
d
all of the above
Answer:
Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.
Explanation:
As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. ... The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.
which is more common grass or humans?
Answer:
Grass
Explanation:
Cause most human food comes from grasses, directly as grain or indirectly as feed for meat and dairy producing animals.
people- estimate that humans have modified >50% of Earth's land surface.
The grass family, Poaceae, is one of the largest plant families, and, to humans, perhaps the most important, as it includes agricultural grains such as wheat, rice, maize (corn), and sugar cane. The Poaceae comprise about 600 genera and perhaps ten thousand species. It is estimated that grasslands cover about 20 percent of the earth's land area.
so the answer is humans
QUESTION 9
Which of the following is not a property of fibre?
O a. It delays gastric emptying
Ob.it
It provides a feeling of satiety
O c It elevates blood glucose levels
O d. It contributes 6-10 kilojoules per gram.
Answer: The correct option is C ( It elevates blood glucose levels).
Explanation:
All animals feed on ready - made food. This food is made up of several groups of substances.All food taken in by an animal can be divided into six groups of food substances or nutrients. They are carbohydrates, proteins, fats and oil, mineral salts, vitamins and water.
Fibres is defined as foods that are usually of plant origin which are indigestible and stimulates movement of the bowels by providing bulk to the intestinal content.
Examples of the plant based food which are rich in fibre include:
--> grains,
--> fruits,
--> vegetables,
--> nuts, and beans.
Fibre is further divided into two:
--> Insoluble fibre: This is also called roughages. They include fruits and vegetables with their backs, whole grains.
--> Soluble fibre: This is the jelly-like fibre that dissolves in water. It includes the flesh of fruits and vegetables, oats.
All fibers can slow the absorption of sugar and fat from food, and therefore help prevent spikes in blood sugar. Therefore the option that fibre elevates blood glucose levels is NOT a property of fibre.
Answer:
c It elevates blood glucose levels
Explanation:
Elevation of blood glucose levels is not the property of fiber because fiber helps control blood sugar. Fiber can't be converted into glucose or fiber does not have glucose so the concentration of glucose can not be increased if more fiber is eaten. Fiber provides a feeling of satiety as well responsible for gastric emptying. One gram of fiber produces 8 kilojoules per gram. So we can conclude that blood glucose level can't be increases due to fiber.
Which celestial objects are formed mostly of the elements hydrogen and helium?

with 75% of their mass being hydrogen and 25% helium.
Celestial objects that are formed mostly of the elements hydrogen and helium are gas giants and dwarf planets. Gas giants are large planets, such as Jupiter and Saturn, which are composed primarily of hydrogen and helium.
What is the reason of calling them Jovian planets ?These planets are also known as Jovian planets, and they are much larger than the terrestrial planets, such as Earth, that are made up of rock and metal. Gas giants have no solid surface and are composed mostly of gas and liquid.
Dwarf planets are smaller than gas giants and are made up of a combination of rock and ice. These objects are too small to be considered full-fledged planets, but they still have characteristics of planets such as an atmosphere, moons, and an orbit around the sun.
Although these objects are composed of different materials than gas giants, they still contain significant amounts of hydrogen and helium. In contrast, rocky planets and asteroids are composed of materials such as rock, metal, and ice. Rocky planets, such as Earth, are composed mostly of iron, silicon, magnesium, and other elements
Hence, . Asteroids are small, rocky objects that are found in the asteroid belt between Mars and Jupiter. These objects are composed of rock, metal, and ice, and contain very little hydrogen and helium.

One conclusion drawn from the experiment was that life span differences were independent of reproductive investment. If that is the case, then which of the following statements is true? Females that exhibited catch-up growth and produced many eggs had longer life spans than females that exhibited catch-up growth and produced few eggs. Females that exhibited catch-up growth and produced few eggs had longer life spans than females that exhibited catch-up growth and produced many eggs. Females that exhibited slowed growth and produced many eggs had longer life spans than females that exhibited slowed growth and produced few eggs. Females that exhibited slowed growth and produced few eggs had longer life spans than females that exhibited slowed growth and produced many eggs. Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.

Chemical reactions of fossil fuels
Difference between biomass and fossil fuels
Comparing biomass with other renewable
energy sources
Making energy choices locally
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.
how proteins are made
Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
Answer:
proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
surrounded by water.
Answer:
The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.
Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
Answer:
Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.
Explanation:
This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.
Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.
I will select plants for my research purpose.
Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.
This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.
This variation helps the plant species to survive better compared to less competent species.
Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.
