The primary oocytes in primordial follicles remain arrested in prophase I of first meiosis in ovary until after puberty. Thus, option D is correct.
What do you mean by oocyte ?Oocytes are the first developing egg cells produced by ancestral oogonia cells of ovary during fetal development.
Oogonia undergo mitosis and produce diploid chromosome containing daughter cells and these oogonia become oocytes.
Oocytes remain dormant until puberty, as it is arrested at early stage of first meiosis as a primary oocyte or primordial follicle.
The average time duration of the conversion of the primordial follicle containing an oocyte to a preovulatory follicle is about 120 days.
Hence option D is correct.

What relationship did boyle and joss-reid (2004) predict about sense of humor and illness symptoms?
The negative correlation relationship did boyle and joss-reid (2004) predict about sense of humor and illness symptoms.
A sample of 504 people divided into three groups was used to study the impact of sense of humour on health.
The following were the hypotheses:
1. Humor would be significantly connected with health after adjusting for other factors.
2. That the evaluation of the factor structure of the Multidimensional Sense of Humor Scale (MSHS) would support its construct validity in the Australian context.
3. That people with a greater sense of humour would report significantly higher levels of good health when compared to those with less humour.
Their findings supported the idea that a sense of humour is linked to health and also validated the MSHS instrument's validity and reliability.

Movement of water where density increases underwater causes deep currents please select the best answer from the choices provided t f
True
Yes, it is true that movement of water where density increases underwater causes deep currents.
Why does movement of water where density increases underwater causes deep currents?With the intervention of two primary mechanisms, winds and density differences, whose origin lies in the contact surface between the atmosphere and the sea, ocean mass is constantly shifted and mixed by more or less fast motions. Despite being slow, the movements of the deep ocean masses are nevertheless considered currents since they pull the water in a specific direction. Differences in density, which are influenced by salinity and temperature, are the cause of this movement.What happens to water's density as salinity levels rise?As the water's salinity increases we can observe its density increase.What are underwater deep currents?Different water densities lead to deep currents, also known as thermohaline circulation. These currents are caused by the sinking of cold, thick water at the poles. Water from the surface circulates on a 1000-year journey around the globe as it flows to replace water that is sinking.To learn more about underwater deep currents visit:

They are frequently linked to memory encoding and the processing of auditory information.The key jobs of the temporal lobes are language comprehension, memory formation, object and face recognition, perception, and auditory information processing.Each cerebral hemisphere's largest lobe, located in front of the occipital lobe, houses a sensory region linked to the auditory system.Different sounds must be interpreted and given meaning by the temporal lobe. As a result, left temporal lobe loss frequently results in receptive aphasia or Wernicke's aphasia, which are issues interpreting language.This crucial component aids in the processing of sensory information, including as pain and auditory inputs.

A cross of a white horse(WW) and a red horse (RR) produces all Roan (RW) offspring. This type of inheritance is called: Incomplete dominance.
Incomplete dominance:Incomplete dominance occurs when one or both alleles of a gene are only partially expressed at a particular location. A different or intermediate phenotype is typically produced by this kind of gene interaction. In the case of incomplete dominance, the variations (alleles) are expressed in a reduced ratio rather than as dominant or recessive.
An allele is a type, variety, or group of gene expressions. A creature is made up of one gene and two alleles, one from each parent. A dominant allele is one that suppresses or conceals other alleles while firmly establishing itself in the offspring. An allele is considered recessive if its effects are suppressed by the dominant allele and do not show up in the progeny.
