c. they were responsible of the Great Potato Famine in Ireland
b. they take the form of sporangia
d. they have hyphae
The answer is (c.) They take the form of sporangia.
The Oomycota or Oomycetes is also known as water molds. In 1840, this type of genus ravaged some parts of Europe especially in Ireland. It is called the Irish Potato Famine. They are rarely to have septa or hyphae but if they do they appear at the bases of sporangia. They only appear on sporangia not takes its form.
Answer:
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
B. cities
C. forests
D. industrial areas
Hedgerows have created new ecosystem within Britain's farms which are patchwork quilts.
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of the dead plants and animals by action of microbes nutrients are released back in to the soil.

The colour of the flowers is the variable in the above-mentioned experiment.
It is a method of performing cross-pollination where the transfer of the pollen grains from the anther of one flower of a plant to the stigma of another flower of a plant happens by the insects.
It is often called insect pollination. The flowers that are pollinated by insects have attractive petals of bright colours. This adaptation ensures that the insects will be attracted to the flowers.
The nectar present in these flowers, on which the insects feed is also sweet with an attractive scent. This is another factor which attracts the insects to the flowers.
It is by way of sucking the nectar that the insects also get pollen stuck on their mouth regions and legs. The pollen grains produced by these flowers are also sticky.
Therefore, to examine if monarchbutterflies prefer a specific coloured flower, different plants with different coloured flowers need to be used and the colour of the flowers will be the variable.

Answer Explanation:
A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.
When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.
