Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
C is the only bad sounding thing out of this bunch.
Answer:
a) Myelinated nerve fibres
b) The white matter
c) gray matter
Explanation:
The three main parts of cerebral hemispheres are
a) Myelinated nerve fibers
b) The white matter
c) Gray matter
The nerve fibers of the white matter are responsible for connecting the functional parts of cerebral cortex while the gray matter is further divided into four surface folds/lobes with each lobe associated with a specific activity. Such as frontal lobe take cares of motor activity and speech, parietal lobe is responsible for touch and position sensation, occipital lobe for vision and temporal lobe for hearing.
Answer:
See the answer below
Explanation:
Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.
<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>
Answer:
The correct answer is - c) Pathology.
Explanation:
Mycology is the branch of biology in which students study fungi and their characteristics including their biochemistry, taxonomy, and genetics.
Agronomy is the other branch of biology that deals with agriculture and its practices and work to improve the crops.
Phycology is the study of algae and their characteristics including their biochemistry, taxonomy, and genetics.
The disease and its causes are studied under the pathology branch o biology therefore, red rust would be studying in this discipline.
