The correct Answer is:
To answer the question regarding the black spots found in Rhizopus during asexual reproduction, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Organism**: Recognize that the organism in question is Rhizopus, which is a type of fungus. 2. **Understand the Structure**: Rhizopus has a mycelium that appears white and cottony. This mycelium is made up of branching structures called hyphae. 3. **Types of Hyphae**: There are three types of hyphae in Rhizopus: - **Stolons**: These are horizontal hyphae that connect different parts of the mycelium. - **Rhizoids**: These are root-like structures that anchor the fungus to its substrate and help in nutrient absorption. - **Sporangiophores**: These are unbranched hyphae that bear sporangia. 4. **Asexual Reproduction**: During asexual reproduction, Rhizopus produces structures called sporangia at the tips of the sporangiophores. 5. **Characteristics of Sporangia**: The sporangia are rounded and contain numerous multinucleate spores. These are the black spots observed on the white cottony mycelium. 6. **Conclusion**: Therefore, the black spots seen during asexual reproduction in Rhizopus are identified as sporangia. ### Final Answer: The black spots during asexual reproduction in Rhizopus are **sporangia**. ---

Which of the following shows asexual reproduction? Yeast, hydra, insects

Consider the following statements and select the incorrect ones. I. Honeybee has developed arrhenotoky in which the male develop from the fertilised egg and the female from unfertilised egg. II. In the thelytoky, the haploid unfertilised egg parthenogenetically develop into females. III. Heterogamy is the alteration between parthenogenesis and asexual reproduction. IV. Parthenogenesis occurs naturally during reproducing in ants and aphids. Choose the correct codes.

Read the following statement and find out the incorrect statement. (a). Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively complex organisations. (b) In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into yeast organism (cells). (c). vegetative reproduction is also a type of asexual reproduction. (d) While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants the term asexual reproduction is frequently used. (e) Water hyacinth is also called 'Terror of Bengal'

Figure shows a torch sending a parallel beam of light fixed on a wall and a plane mirror which forms a spot on the wall. As the mirror moves towards the wall, the spot on the wall moves

Figure shows a plane mirror hinged at O and free to rotate in a vertical plane. The point O is at a distance x from a long screen. A beam of light moving vertically downwards is reflected by the mirror at O so that a bright spot P is formed at the screen. At the instant shown, the angle of incidence is theta and the mirror is rotating clockwise with constant angular veloity omega . Find the speed of spot P at this instant.

Generally, we consider that during slowing of a moving automobile, its retardation is constant, but in practice this is seldom the case. Under many circumstances, especially at high speed, we usually apply the brakes slowly at first and then more strongly as the car slows. The braking force therefore depends on the time during the interval over which the car is slowing and acceleration changes with time. a_(x)(t)=(v_(A)-v_(x))/(dt) =(F_(x)(t))/(m) int_(v_(0_(x)))^(v_(x))dV_(x)=int_(0)^(1)(F_(x)(t))/(m)dt therefore V_(x)=V_(0x)+(1)/(m) int_(0)^(1)F_(x) (t) dt x(t)=x_(0)+int_(0)^(1) V_(x) (t) dt An example for the same is discussed here. A car of mass m = 1000 kg is moving with 25 m/s. The driver begins to apply the brakes so that the magnitude of the braking force increases linearly with time at a rate of 2000 N/s. Read the above passage carefully and answer the following questions. Find the velocity of the car at t = 10 sec.

A metal foil is at a certain distance from an isotropic point source that emits energy at the rate P. Let us assume the classical physics to be applicable. The incident light energy will be absorbed continuously and smoothly. The electrons present in the foil soak up the energy incident on them. For simplicity , we can assume that the energy incident on a circular path of the foil with radius 5xx10^(-11) m (about that of a typical atom ) is absorbed by a single electron. The electron absorbs sufficient energy to break through the binding forces and comes out from the foil. By knowing the work function, we can calculate the time taken by an electron to come out i.e., we can find out the time taken by photoelectric emission to start. As you will see in the following questions, the time decay comes out to be large, which is not practically observed. The time lag is very small. Apparently, the electron does not have to soak up energy . It absorbs energy all at once in a single photon electron interaction. The experimental observations show that the waiting time for emission is 10^(-8) s. This observation contradicts the calculations based on classical physics view of light energy . Thus we have to assume that during photoelectron emission
