Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.
Explanation: ^
Continuous conduction takes place in unmyelinated axon.
Explanation:
Based on the presence and absence of myelin sheath, the neurons had been classified as myelinated and non-myelinated neurons respectively.
In myelinated neurons the transmission of impulse takes place only at the non myelinated region called nodes of Ranvier. Due to this, the conduction in Myelinated neuron is saltatory.
The conduction in non-myelinated neuron takes place throughout the length of axon and it is continuous.
Saltatory conduction is faster than continuous conduction.
True ..In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".
As the head organ in the body which controls, monitors, supervises and influences the different organ system in the body and of the individual -characteristics, personality, traits, cognition, perception, intelligence, sensation and motor responses. The brain controls the endocrine system by its part, located somwhere in the medial temporal lobe called the hypothalamus, the master gland of the body. The hypothalamus influences every gland secretion and hormonal function that preceeds and proceeds in the body of an organism -growth, drives, sex, survival and etc.
The hypothalamus sends sgnals from the different gland organs in the body that either exhibits or inhibits the activity of that particular gland releasing hormone.
Answer:
C. The differences between the observed and expected counts are too large to be attributed to chance.
Explanation:
The p-value of the statistic represents the chance that the observed count is based on luck or chance. When p value too high, the research can't be used since the chance that its not represent real condition are too high. Most researchers use 5% (0.05) as the cutoff of something called statistically significant. In this research, the p-value is 0.04 or 4%, so it is statistically significant.
