How do I explain this? ‘The plant shows the characteristic responding to environment because...’

Answer:

Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.

Explanation:

Pollen grains contain the male gametes of a sexually reproducing plant. Pollen grains are haploid cells in nature produced by the meiotic division of microspore mother cells (located in the anther). The meiosis of these diploid (2n) microspore mother cells give rise to four haploid microspores. This process in plants is called microsporogenesis.

Each haploid microspore (n) develops into pollen grain called microgametophye (bearing male gamete) via mitotic division. During the pollen grain formation, a wall is formed around the microspores.

Answer Internal and external environmental factors, like gender and temperature, influence gene expression. ... Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.

Answer:

stable

Explanation:

Another word that can be used to describe homeostasis is - stable

It is an organism's process of maintaining a stable internal environment suitable for sustaining life. It describes the internal stability of an organism.

Most of the homeostasis process is maintained by the cell membrane by allowing what or what not to enter or exit in the cell, however, the complete cell takes part in the homeostasis.

Explanation:

By definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.

First, you have to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.

Photosynthesis takes place in 2 stages:

Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.

Explanation:

It would be wrong for SpongeBob to conclude that giving flower power fertilizer helps the plant to produce more flowers based on the experimental design.

There are fundamental flaws in the experimental design that could make the conclusion to be wrong:

In order to investigate if the flower power fertilizer has the capacity to help the plant to produce more flowers, the two plants used should have been subjected to the same conditions barring only the fertilization application. Whatever difference that is observed in the number of flowers produced can then be attributed to the fertilizer.

Also, the number of plants for each group (with and without fertilizer) is too small to arrive at a reliable conclusion. In scientific investigations, replicating measurements increases the statistical power of the resulting data and raises the reliability of the conclusion.

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

In order to calculate the percentage decline over the period of time between 1979 and 2007, the general formula for percentage change will be applied. This is as follows:

[tex]\frac{B-A}{A} \times 100[/tex]

where:

A = final value

B = initial value

In this problem:

A = Initial population = 1,300,000

B = Final population = 640,000

Applying this formula to the problem, the percentage change in population between 1979 and 2007 is as follows:

[tex]\frac{B-A}{A} \times 100\\\\\frac{640,000 - 1,300,000}{640,000} \times 100 \\\\\frac{-660,000}{1,300,000} \times 100\\\\= \frac{-66,000,000}{1,300,000} \\\\= -50.769 \%\\= 50.77\% \\Note\ that\ the\ minus\ sign\ denotes\ a\ decline.[/tex]

B: The change in range over this period of time is the difference between the final population and the initial populations, which is calcalated thus:

B - A (as explained above)

= 640,000 - 1,300,000 = - 660,000 (the minus sign still shows a decline)

While the percentage shows a "relative change" in terms of percentage, the change in range shows an absolute or actual change.

Answer:

In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule. Proteins are built from smaller units called. An exon is the portion of a gene that codes for amino acids. In the cells of plants and animals, most gene sequences are broken up by one or more DNA sequences called introns.
