Answer:
c. founder effect
Explanation:
The founder effect occurs when there is a loss or reduction of genetic variation when a new population is produced or established by a few number of individuals from a large population. In other words, a new colony is formed from a large population. This could result to differences in phenotype ad genotype of the new population from the original population.
The gene pool of the new population is also affected. The small group of squirrels that separated from the the large population during the flood to form a new population, is an example of founder effect.
O the mechanism of death
O the time of death
the manner of death
A forensic autopsy can accurately identify the cause of death, mechanism of death, and manner of death, but it is least likely to accurately identify the time of death.
A forensic autopsy is a thorough examination of a deceased person's body to determine the cause of death, mechanism of death, manner of death, and sometimes the time of death. While a forensic autopsy can accurately identify all of these factors, it is least likely to accurately identify the time of death. Determining the exact time of death can be challenging, as it depends on various factors such as temperature, environmental conditions, and the stage of decomposition.

Answer:
Explanation:
B.Blastocyst
C.morula
D.Blastocoel
Ans.
Embryogenesis or embryonic development is defined as a process that involves formation and development of a zygote into embryo. The fertilized egg or zygote undergoes mitotic divisions through cleavage and divides rapidly.
The first stage of embryonic development is known as morula that represents a 16 cells consisting solid ball-like structure. The morula later develops into blastula.
Thus, the correct answer is option C). 'morula.'
B. The flower absorbs and refracts light.
C. The flower reflects and refracts light.
D. The flower refracts and blocks light.
Answer:
Many insects stridulate when they are handled or attacked. It has been suggested that this disturbance stridulation acts to deter predators. This hypothesis was investigated in a series of experiments. Predators were given insects which had been silenced by disruption of their sound-producing mechanism or else had been sham operated but retained their normal ability to stridulate. 2. Three types of insects (mutillid wasps, Dasymutilla spp.; water scavenger beetles, Tropisternus spp.; and round sand beetles, Omophron labiatus) were given to wolf spiders (Lycosa ceratiola and Geolycosa ornatipes) at night in the field under natural conditions. When attacking silenced insects, spiders displayed greater persistence than when attacking phonic insects (Table 1). In addition, mortality was greater among silenced insects. 3. Spiders (L. ceratiola) were also given an artificial 'insect' - a vibrating probe whose vibration mimicked that of the cuticle of a stridulating insect. As with real insects, spiders persisted longer in their attack on the probe when it was silent than when it was 'stridulating.' 4. Female mutillid wasps were given to wild-caught mice (Peromyscus floridanus) in the laboratory. Unsilenced mutillids survived the encounter more often than their silenced counterparts. In another experiment, the stings of mutillid wasps were removed before testing. Mice killed nearly all these 'unprotected' mutillids. However, it took mice significantly longer to attack unsilenced mutillids and longer to kill them after initiating the assault (Table 2). 5. These results support the view that insect disturbance stridulation deters predators. Two modes of action by which these sounds may have their effect are discussed: they may serve to startle the attacker or they may alert it to the potential harmfulness of the insect and as such may qualify as an example of acoustic aposematism.
