The borders (coastlines) of the continents underwent a number of changes since the split. Often, chunks of land were washed away with water, slowly or in bigger portions. The coast was generally "smoothed" by the ocean currents too, and in some places more land was added with the material that the ocean currents brought.

Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.

Give one real life example of an enzymatic reaction in the human body.
son4ous [18]

Answer:

Enzymes are the bio-catalyst produced by the body.

They increases the rate of bio-chemicals reaction taking inside the body.

They form enzyme-substrate complex in order to increase the rate of the reaction.

They are highly specific in nature.

Example:
  • Hexokinase catalyses the conversion of glucose to glucose-6-phosphate.
  • Salivary amylase catalyses the breakdown of starch into maltose (simpler sachharides).
  • Protein kinase is an enzyme used to activate or deactivate other by adding phosphate group to them.

The vascular cambium produces secondary phloem and xylem tissue.
Vascular cambium, a plant tissue located between the xylem and the phloem in the stem of a vascular plant. It is also the source of both secondary xylem growth and the secondary phloem growth.  Vascular cambium is usually found on dicots and gymnosperms not on monocots which usually lack secondary growth. It does not transport water, dissolved food or minerals by plants.Vascular cambia are cylinders of unspecialized meristem cells which divide  to make new cells which specialize to form secondary vascular tissues.<span> </span>

What is the experimental group
GREYUIT [131]

Answer: In the restaurant business, the use of plastic can sometimes be unpreventable, as it serves many purposes and plays a vital role in our consumption of food. One of the great advantages of plastic is that it’s designed to last for a very long time: nearly all of the plastic ever created still exists in some form today. It is in use all around us — from protecting products, to the interior of our cars, to preserving food, to the medical devices used in hospitals every day. While there are numerous positive characteristics of plastic, there are also some considerable negatives. Every day, many plastic items are only used once and then are thrown away, generating one of the fastest growing problems for the environment. We call this “single-use plastic.”

There are countless amounts of plastic items in our landfills and additionally, in our lakes, rivers and oceans. Since it takes years and years for plastic to decompose, it can release toxic chemicals into our soil and water, which can affect human health and wildlife.

With this in mind, it is important not only for individuals to reduce their plastic use, but for restaurants to lead in example by reducing the amount of plastic generated in the workplace. Many large companies like Starbucks, IKEA, and Disney have already committed to eliminating single-use plastic waste in the near future, and we expect many others will follow suit. Here are five tips to help contribute to reducing plastic waste:

You have mated a phenotypically wild-type female of the genotype Xy+w+Xyw to a male with the genotype XywY. You counted 2205 tot
Vinil7 [7]

Answer:

1.31 cM

Explanation:

Total offspring = 2205

Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.

Recombination frequency = (Number of recombinants / Total progeny) * 100

= [ ( 17 + 12 ) / 2205 ] * 100

= ( 29 / 2205 ) * 100

= 1.31 %

Map distance = Recombination frequency

Hence, distance between two genes = 1.31 cM
