5.

The pollen grain represents aA) male sporophyte B) male gametophyte C) female sporophyte D) female gametophyte

Answer»

The pollen grain REPRESENTS a male gametophyte.

Option: B

Explanation:  

  • The pollen Grain is secreted from the anther of the plant. The anther is the male REPRODUCTIVE organ of the flowers.  
  • Pollen is a gametophyte and not a sporophyte. This is because of sporophyte CONSISTS of diploid number of chromosomes.  
  • On the other hand gametophytes consists of HAPLOID number of chromosomes because they are produced by meiosis which reduces the ‘number of chromosomes’ to half.  
  • Pollen grain is an example of a male gametophyte.

Explain the process of formation of complex protiens

Answer»

Hey......!!! :)) ✌️✌️

______________
______________

Formation of complex proteins :-

A protein complex is a collection of proteins that interact with each other at the same time and location, and which has essential roles in regulatory processes, cellular functions, and signaling cascades.


Process:- Protein Synthesis

Now that we’ve described DNA and RNA, it’s time to take a look at the process of protein synthesis. The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell’s NUCLEUS and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.


Transcription

The FIRST step in transcription is the partial unwinding of the DNA molecule so that the portion of DNA that codes for the needed protein can be transcribed. Once the DNA molecule is UNWOUND at the correct location, an enzyme called RNA polymerase helps line up nucleotides to create a complementary strand of mRNA. Since mRNA is a single-stranded molecule, only one of the two strands of DNA is used as a template for the new RNA strand.

The new strand of RNA is made according to the rules of base pairing:

DNA cytosine pairs with RNA guanine

DNA guanine pairs with RNA cytosine

DNA thymine pairs with RNA adenine

DNA adenine pairs with RNA uracil

For example, the mRNA complement to the DNA sequence TTGCAC is AACGUG. The SAT II Biology frequently asks about the sequence of mRNA that will be produced from a given sequence of DNA. For these questions, don’t forget that RNA uses uracil in place of thymine.

After transcription, the new RNA strand is released and the two unzipped DNA strands bind together again to form the double helix. Because the DNA template remains UNCHANGED after transcription, it is possible to transcribe another identical molecule of RNA immediately after the first one is complete. A single gene on a DNA strand can produce enough RNA to make thousands of copies of the same protein in a very short time.

Translation

In translation, mRNA is sent to the cytoplasm, where it bonds with ribosomes, the sites of protein synthesis. Ribosomes have three important binding sites: one for mRNA and two for tRNA. The two tRNA sites.


Function of complex protein:-

Proteins come in a huge variety of forms and perform a wide range of functions. Examples of proteins include enzymes, antibodies and some hormones which help to speed up chemical reactions, defend against diseases and regulate the activity of cells.

example of complex protein:-

Many proteins such as myoglobinconsist of a single polypeptide chain; others contain two or more chains. For example, hemoglobin is made up of two chains of one type (amino acid sequence) and two of another type.

What is meant by positive and negative tropic movements in plants and give example?

Answer»

Hey friend,
Here is your answer:

• Tropic movement or tropism is the movement of a PART of a plant in response to an EXTERNAL STIMULUS. Example : phototropism, geotropism, hydrotropism, thigmotropism.

• Positive tropic movement is the movement of a part of a plant when it grows towards a stimulus. Example: growth of stem towards light.

• Negative tropic movement is the movement of a part of plant when it grows AWAY from the stimulus. Example : growth of stem away from WATER and gravity.

Define triple fusion?what is the product of the process what does this product develop into

Answer»

Triple fusion -
The pollen grain contains TWO MALE gamete .
One of the gamete fuse with egg ( female gamete ) to form zygote this process is CALLED syngamy .

The other male gamete FUSES with the TWO POLAR NUCLEI , one from each end of embryo sac, to form ENDOSPERM NUCLEUS . This process is called triple fusion, in this process THREE NUCLEI , TWO POLAR NUCLEI AND ONE MALE GAMETE is involved , so it is called triple fusion .

After FERTILIZATION , the ovule develops ino SEED and develops into a FRUIT

How do biotic and abiotic factor affect crop production ?

Answer»

The REASONS are there are some biotic factors like pest, insects and some sort of diseases. will affect the crop production. pest occur damage crop production by feeding. even THINGS like WEEDS is also affect crop production by competiting with important crop for use of nutrients and light. abiotic factors are nothing but temperature , wind, air, rain and etc. it HEAVILY affect the production by through natural disasters like droughts, and floods.  so these are the reasons for the biotic and abiotic factor affect crop production. hope it HELPS.

Why are reptiles not dependent on water like amphibians?

Answer»

Hii...

here is your answer. ...

⤵⤵⤵⤵⤵⤵⤵⤵⤵

Reptiles does not depend on water LIKE amphibians for REPRODUCTION.

Reptiles are a egg LYING animals. and they have strong shell on eggs so it can be prevented from water.

It's skin is dry so not require water more. Reptiles have SUFFICIENT water in there body.

The water can be SUPPLIED in embryo by its own. .

so reptiles are independent.

Difference between parasitic and epiphytic plants with examples

Answer»

nteractions between organisms are important for the continuance of an ecosystem and enrichment of ecosystem biodiversity. Various types of INTERACTIONS can be seen in an ecosystem. Symbiotic interactions and parasitic interactions are significant among them. Some interactions are beneficial for both members involved in the interaction while some interactions are DRIVEN at the EXPENSE of one member. Epiphytes and parasites are two groups which show two such interactions. Epiphytes are defined as plants that grow on other plants; they depend on other plants for physical SUPPORT, without obtaining nutrients or without causing any harm. Parasites are defined as organisms that live on or in other organisms; they obtain nutrients and other requirements while causing loss or harm to the host organism. The key DIFFERENCE between epiphytes and parasites is that epiphytes only depend on other plants for physical support whereas parasites obtain nutrients and other requirements from their hosts.

A type of WBC (white blood cells) is referred to as Polymorphonuclear Leucocytes or Granulocytes. They contain granules. They are named so because of the varying shape of their nucleus. They are again of three types namely Neutrophils, Eosinophils and Basophils.

However, in common man’s language, by polymorth they usually refer to the Neutrophils, that are present in the highest number as compared to other PMNL(Polymorphonuclear Leucocytes) such as Eosinophils and basophils.

Temporary or transient increase under normal circumstances may occur in case of acute stress or after heavy exercise.

Increased number of neutrophils under pathological or diseased condition signal:

Infection, Bacterial

Any acute inflammation

Tissue destruction or death(necrosis) as in Infarction(heart ATTACK), burns, neoplasia(TUMOR)
