<span>There are two major theories that will explain on research on colour vision. They are 1. the trichromatic theory also known as the Young-Helmholtz theory 2. opponent-process theory. These two theories explain processes that operate at different levels of the visual system.</span>
Answer:
<h2> FFEE, FfEE, FFEe, and FfEe</h2><h2> All the progeny show same 1/4 or 25% probability.</h2>
Explanation:
Given; parents are with genotype FFFe and FfEE
F/f and E/e are showing independent assortment,
1. Genotype of all possible offspring are;
gamete from parent FFEe are; FE and Fe ,
gamete from parent FfEE are; FE and fE.
So genotype of offspring are: FFEE, FfEE, FFEe, and FfEe
2. All the progeny show same 1/4 or 25% probability.
Answer:
- Because soil has lost nutrients.
- To provide the right nutrients needed by a particular plant to grow.
Explanation:
Due to regulkar use of soil, the nutrients in the soil have been constantly used by the plants grown on it.
Due to this, soil has lost its value.
Application of fertilizer is one wey through which farmers artificially provide nutrients to the soil.
Therefore, application of fertilizers becomes neccessary for improved crop productivity.
Answer:
The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>
Explanation:
The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
Animal cell structures and organelles interact as a system to maintain homeostasis by making sure each part of the system works together.
