In heterosporous plants microgametophytes produce sperm.

What are heterosporous plant ?

Heterosporous refers to the plants producing different types of spores that are different in structure, size and function.

What does heterosporous plant produce?

In heterosporous plants, there are two sizes of spores; the smaller (a microspore) produces a male gametophyte, and the larger (a megaspore) produces a female gametophyte.

Hence ,the correct option is B

Symbolic mechanism of rituals such as family meals

Rituals are repeated set of actions and behaviours that has a significant value. Symbolic mechanism of rituals such as family meals, holidays and apple picking every fall helps families to strengthen and renew their bonds and also spreads family values and culture from one generation to the next.

A parasitic association is one in which a species, the parasite, thrives off of another species, that is, the host, affecting it, and at certain occasion resulting in death. The parasite lives on or within the body of the host.

An ectoparasite refers to the parasite, which thrives on or in the skin, but not inside the body. For example, lice, ticks, and fleas are ectoparasites. Hence, the correct answer is option B.

Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra.

Answer: Option D

Explanation:

In our body, presence of urinary tract filters extra fluid and other substance from the blood. The substances get excreted from our body in the urine type.

Urine, a liquid generated by the kidneys, accumulates in bladder, and then excreted from the urethra. Urine used to remove excess minerals and to remove blood cells from body. The urinary tract consists of the kidneys, urethra, bladder and ureter.

The urinary systems function in conjunction with other systems of the body to handle homeostasis. The kidneys play as the important organs of homeostasis. They balance acid-base and water-salt in the blood.

Explanation: This experiment clearly represents the interaction between the atmosphere and the biosphere.

        Biosphere refers to the overall life forms on earth and their relationship with other elements that are present in the lithosphere, hydrosphere of geosphere.

Here the leaves where Jake tied plastic bags re considered to be part of biosphere, which he keeps it to react with the atmosphere.

Thus the correct answer is option (1).

Both cellular respiration and fermentation use sugar, amino acids, and fatty acids as building blocks to create ATP, but their processes and the amount of energy they release are different. 3. While fermentation only generates 2 ATP, cellular respiration generates 38 ATP.

Through the activity of enzymes, fermentation is a metabolic process that results in chemical changes in organic substrates. It is specifically described in biochemistry as the process of obtaining energy from carbohydrates without the presence of oxygen.

Fermentation may be divided into three primary categories: lactic acid fermentation, ethanol fermentation, and the creation of hydrogen and methane gas.

Similar to burning, cellular respiration causes the full oxidation of glucose into CO2 and water. Contrarily, fermentation only partially oxidizes glucose. Instead, waste is created in the form of tiny, reduced organic molecules.

Thus, glucose is released into the cell's respiration process more often than it is into fermentation.

A male mouse that is heterozygous for a mutant igf2 allele (igf2/igf2-) is crossed with a female who is homozygous for the wild-type igf2 allele. The expected outcome of this cross would be fifty percent of homozygous wild type and fifty percent of heterozygous mutant species.

Further Explanation:

The allele that codes the particular phenotype which is most common in a population is called the wild type allele. Mutant allele is referred as different type of allele from wild type. Wild type is dominant in nature. A recessive trait is defined as a trait that gets expressed by an individual when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as recessive trait gets concealed by the presence of allele for dominant trait.

If the wild/normal gene is igf2 and the mutated gene is igf2-, then the genotype of the parent would be:

Then the resultant cross gives fifty percent of heterozygous for a mutant (igf2/igf2-) and fifty percent of homozygous for the wild-type (igf2/igf2).

Only cytotoxic T-cells cells can enter the affected cells and kill the pathogen. In humoral response, B cells are involved but these are not present in the image.

The fat bodies are generally larger in female frogs compared to males. This size difference is attributed to the roles these fat bodies play in reproduction.

In female frogs, the fat bodies serve as an energy reserve that is crucial for the production of yolky oocytes, which are essential for successful reproduction. These fat bodies store energy in the form of lipids and provide the necessary nutrients for the developing embryos.

During the reproductive cycle, female frogs undergo vitellogenesis, the process of yolk formation in the oocytes, which requires a significant amount of energy. The fat bodies mobilize lipids to support this energy-intensive process. Males, on the other hand, do not have the same reproductive demands and therefore typically have smaller fat bodies. Their reproductive role primarily involves producing sperm, which does not require the same level of energy storage as egg production.

Additionally, the size of the fat bodies can fluctuate seasonally and with the reproductive status of the frog. They tend to be largest during the breeding season when females are preparing to produce eggs. After oviposition (egg-laying), the fat bodies may shrink significantly as the stored energy is depleted.

In summary, the larger size of fat bodies in female frogs is a reflection of their greater energy demands for reproductive purposes, particularly in the production of eggs with substantial yolk reserves to support embryonic development.

Correct answer: D). Duplication

It is a disease that is caused by the repetition of codon for many times, which will lead to inactivation of gene that is required for the proper function of brain and other body functions. It is a sex linked genetic disorder, which is caused to to lengthening or expansion of genes.

In these disease the codon triplet CGG is repeated several times, which causes mutation in the gene CFR1. The main symptoms of this disease is mental impairment and heart problem etc.
