Answer:
The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.
Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.
Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.
Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.
The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.

write any two method for identification of fossils?
Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.
What are the ways by which fossils form ?Molds and the casts are the ways by through the fossils are formed out.
Something becomes fossil then it is mineralized or later becomes is made of the minerals. This is usually meaning an increase in the weight. A fossil bone is just heavier than the normal bone that is noticeably so. So if object is heavy then it just might be the fossil. Sediment might fill mould and later form cast fossil.
Have an eye that looks for the detail Look for the regular lines along with the marks or the patterns on the pebbles just like ridges or the growth lines in the shell. Looking for the tiny pieces that are among the beach pebbles and not only the big stones. Often the crinoid stems or the belemnites can also be small as the little fingernail.

beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.
If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.
Energy Storage in Humans Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. What is the best conclusion based on this data? Blood is a primary location for energy storage. Fat molecules contain more energy-containing bonds than simple sugars. A gram of glycogen has twice as much energy as a gram of fat. The human body stores approximately 1,000 kcal of glucose.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)

The researchers predicted that for any particular concentration of substrate, the C. Aurantiacus enolase catalyzedreaction is more rapid at 55 C. Than at 37 C. Provide reasoning to justify the researchers prediction.
Answer:
It's justified because an increase in temperature will lead to increase in the enzyme catalyzed reaction
Explanation:
Now, as the temperature is increasing, the kinetic energy of molecules will also be increasing and this implies that the collision between the substrate and enzyme will increase i.e substrate that's attached to its appropriate active site of enzyme that results in an increase in reaction.
However, if the temperature is too high, it can cause the enzymatic activity to denature.
In summary, when talking about catalyzed reactions, an increase in temperature will cause the bond between molecules to loosen and this results in catalyzation.

An Allele which express itself during gamete formation is termed as:
Answer:
the ability of one allele to express its phenotype at the expense of an alternate allele; the major form of interaction between alleles; generally the dominant allele will make a gene product that the recessive can not; therefore the dominant allele will express itself whenever it is present.
Explanation:
Answer:
Alleles occur in pairs. Out of two alleles, only one allele expresses itself in the hybrid and prevents the expression of the other allele. The allele which expresses itself in the hybrid is called dominant allele and the other allele which is unable to express in the hybrid is termed as recessive allele.

The G1Phase
is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. Interphase is important before mitosis begins because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same.

Which statements describe incomplete dominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Incomplete dominance involves the interaction of two alleles. which ones are right?
Answer:
Traits are neither dominant nor recessive.
Offspring exhibit an intermediate form of alleles from the parents.
Incomplete dominance involves the interaction of two alleles.
Explanation:
In genetics, incomplete dominance (also known as partial dominance) is produced when the dominant allele doesn't mask the effects of the recessive allele, which is also expressed in the phenotype. In consequence, heterozygous organisms for a gene exhibiting incomplete dominance will be a mix (or blend) as a result of the expression of both characters. In humans, for example, Tay-Sachs disease is a genetic disorder characterized by a gene that exhibits incomplete dominance, where heterozygous individuals are still able to produce a key enzyme (hexosaminidase A) due to expression of the wild-type allele, while homo-zygous individuals for Tay Sachs recessive mutation usually die by the age of 4.
