Steps of Double Fertilization.

1. Germination of pollen on stigma :

(i) By absorbing secretion of stigma pollen swells up and outer layer exine ruptures whereas inner lintine comes out in the form of pollen tube.

(ii) Branched polen tube is formed in amentiferae group.

(iii) In families malvaceae, cucurbitaceae, etc. polysiphonous condition (many pollen tubes from a single pollen) is found.

2. Path taken up by pollen tube :

(i) Pollen tube pierces through stigmatic papilla into the tissue of style.

(ii) Filiform apparatus of synergids secrete some chemotropically active substances, which promotes porogamy.

(iii) Obturator (special structure) act as a bridge for growth of pollen tube.

(iv) Cations are naturally occurring chemotropic agents in the pistil.

3. Entry of pollen tube into embryo sac :

(i) It enters into the ovule by either of the two methods; porogamy, chalazogamy or mesogamy.

(ii) Irrespective of the mode of entry of pollen tube into the ovule, the pollen tube always enters into embryo sac at micropylar end (Porogany).

(iii) If enters through chalaza (base) it is termed chalazogany.

(iv) If pierces through integuments, it is called mesogamy.

(v) Tip of pollen tube penetrates embryo sac and reaches egg apparatus.

4. Syngamy (Generative fertilization)

(i) Pollen tube burst as tube nucleus disorganises.

(ii) One of male gametes fuses with egg cell or oosphere.

(iii) Deploid oospore or zygote is formed.

5. Triple fusion (Vegetative fertilization) :

The other gamete fuses with secondary nucleus forming triploid primary endosperm (PEN) which later give rise to endosperm.

They contain reserve food material that provides nourishment to the developing seedling. The function of Cotyledons is to store food for the growing embryo.

The factors that should be labelled C (constant) or V (variable) are as follows

Molecule size - V

Material used as the membrane - C

Amount of substances used - C

Number of trials - C

whether the molecules diffused through the membrane (tubing) V

In an experiment, constants are the factors that are kept the same throughout the experiment. Variables are the factors that are changed or measured during the experiment.

Constants are important because they help to ensure that the results of the experiment are accurate. If one or more constants are changed, it can be difficult to determine which factor is causing the change in the results.

Variables are important because they allow the experimenter to test the relationship between different factors. By changing one variable and keeping the others constant, the experimenter can see how the change in the variable affects the results of the experiment.

The above answer is based on the full question below

Label each factor below V if it was variable during the procedure or C if it was constant.

Answer:

The face of the child is 3.0 cm from the ornament.

Explanation:

Diameter of the ornament = 8.0 cm

radius = \(\frac{diameter}{2}\)

          = \(\frac{8.0}{2}\)

radius = 4.0 cm

But,

focal length of the ornament (f) = \(\frac{r}{2}\)

                        = \(\frac{4.0}{2}\)  = 2.0

So that,

f = 2.0 cm ............... 1

Also,

Magnification = \(\frac{Image distance}{Object distance}\)

\(\frac{1}{2}\) = \(\frac{v}{u}\)

v = 2u ............. 2

Substitute equations 1 and 2 in the mirror formula,

\(\frac{1}{f}\) = \(\frac{1}{u}\) + \(\frac{1}{v}\)

\(\frac{1}{2}\) = \(\frac{1}{u}\) + \(\frac{1}{2u}\)

  = \(\frac{2 + 1}{2u}\)

\(\frac{1}{2}\) = \(\frac{3}{2u}\)

6 = 2u

u = \(\frac{6}{2}\)

u = 3.0 cm

Thus, the face of the child is 3.0 cm from the ornament.

Answer:

Evolution is a gradual change in the inherited traits of a population over many generations.

Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes. The natural environment selects for these members over others in the population.

Over many generations, because more of the best suited members have been reproducing, the population all now have the trait that makes them better suited for the environment.

This population has now evolved to better suit its environment, through the process of natural selection.

ATP is the energy currency of biochemical reactions in the human body. On the other hand, a polymer of this monosaccharide (beta glucose) is cellulose, which is found in plants as part of their cell wall.

We can conclude that the correct answer is:

C. carbohydrates

Answer:

?

Explanation:

Answer:

The reason you eat is to ultimately create a molecule called ATP (adenosine triphosphate) so that your cells have the means to power themselves, and therefore you, along. And not incidentally, the reason you breathe is that oxygen is needed in order to get the maximal amount of cell energy from the precursors of the glucose molecules in that food.

The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. It consists of a series of stages, beginning in the cell cytoplasm and moving to the mitochondria, the "power plants" of eukaryotic cells. The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).

The statement that best describes the future generations of these bacterias is that they will be produced by asexual reproduction and will be more resistant to the antibiotic. So the correct option is 1.

Antibiotics are drugs that will be used to combat bacterial infections that cause diseases, hindering their reproduction and growth. It is important to know which is the agent that is affecting the individual to see if the use of antibiotics is necessary, since if their use is abused and used in viral diseases, resistance can be generated, making it difficult in the future to combat bacterial infections. It can also affect the intestinal flora by consuming it continuously.

The characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics.

What is morphology?

Morphology is the study of the form and structure of living organisms, including their physical and anatomical features. In biology, morphology is used to describe the appearance, shape, and size of different parts of an organism, such as its organs, tissues, cells, and even its molecules. This includes the study of external and internal structures, as well as their function, development, and evolution. Morphological characteristics are often used in the classification and identification of different species, as they can provide important clues about an organism's evolutionary history, ecological niche, and relationship to other organisms.

We assume you are referring to the scientific classification of bananas in the plant kingdom. In this case, the characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics. Bananas belong to the genus Musa, which is part of the family Musaceae.

The characteristics used to classify plants into different taxonomic groups include their structural features, such as their leaves, stems, flowers, and fruit, as well as their genetic and evolutionary relationships.
