How do flowering plants reproduce by fertilization if they are immotile?

Answers

Answer 1

Answer: the way that flowering plants reproduce by fertilization if they are immotile is : the pollen that they carry it gets passed by bees and pollinators such as butterflies and they start switch genetics

immotile plants are the plants that couldn't do a voluntary movement, which means they can voluntarily move their reproductive organs to make the copulation. These reproductive organs could accidentally touch each others when the bees trying to get nectar from the plant

A DNA strand has the codon AAT. According to the chart, the corresponding messenger RNA codes for which amino acid?

Answers

Answer:

Asparagine (symbol Asn)

Explanation:

In a gene, groups of three nucleotides (such as AAT) form codons that are read during translation, for the synthesis of proteins. The way codons are read can be found in a genetic code (attached here).

Before that, the DNA seuqences are transcripted to RNA sequences in order to be read and translated in the ribosome.

AAT (DNA sequence) will be transformed to AAU during the transcription of DNA. This is because during the transciption process all thymines (T) are replaced by Uracils (U).

In the genetic code you can see that AAU is read as Asparagine.

Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.

What is the primary product of light independent reactions

Answers

The primary products of the light independent reactions (after one turn of the cycle) are:

a) two G3P molecules

b) three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.

One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.

The U.S.-Mexico border 2012 program’s goal is to _______. a. prevent illegal immigration
b. improve transboundary ecosystem health
c. promote joint economic development
d. reintroduce endangered species

Answers

The correct answer is (b) improve transboundary ecosystem health.

The main goal of this mission was to improve the transboundary ecosystem by improving the health in the U.S border and to make it consistent by the help of sustainable development. It includes a variety of area that has to maintained. The air, water and land contamination has to be removed to improve the overall environmental health.

The US - Mexico Border 2012 Program's goal is to improve the transboundary ecosystem health. The purpose of such program is really focused on revitalizing the ecosystem, specifically the environment. Its goal is to reduce the contamination in the air, land and especially water.
