Answer 1

Answer:

2:1

Explanation:

Let the allele for achondroplasia be represented by A.

Since the disease is lethal in AA condition, the two people would rather be Aa.

                         Aa     x     Aa

offspring       AA     Aa     Aa     aa

The AA offspring does not survive, hence, we are left with 3 children out of which 2 are affected heterozygotes and the remaining 1 is a true-breeding recessive and normal.

The expected ratio of affected to normal offspring is, therefore, 2 to 1.

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.

An Allele which express itself during gamete formation is termed as:

Answers

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.

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?

Answers

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.

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.

Answers

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.

write any two method for identification of fossils?

Answers

Fossil identification can be a challenging proposition. Often a small detail is all that seperates one species from another. Still overall classification system is not so difficult to understand.
Fossils of animals are classified, as are living specimens, by observing the body structures and functions. While there are a few unique challenges in classifying fossils, the basic scheme of organization is the same. Going one step at a time can make fossil identification possible for anyone.

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.

What effect do glaciers have on plant life?
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Glaciers bring quantities of minerals that choke plant life as the water runs off melting ice.
Glaciers has no effect on plant life other than helping distribute necessary water.
Glacial flooding is destructive to plant life as silt builds in rivers.

Answers

Answer:

Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.

Explanation:

Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.

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.

Answers

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.
