Answer:
As soon as the concentration passed 39, the plants died. Adding to that, I have also found out that the lower the concentration of the sugar, the more the average height becomes.
Explanation:
Plant growth and development are tightly controlled in response to environmental conditions that influence the availability of photosynthetic carbon in the form of sucrose. Trehalose-6-phosphate (T6P), the precursor of trehalas in the biosynthetic pathway, is an important signalling metabolite that is involved in the regulation of plant growth and development in response to carbon availability. In addition to the plant’s own pathway for trehalas synthesis, formation of T6P or trehalas by pathogens can result in the reprogramming of plant metabolism and development. Developmental processes that are regulated by T6P range from embryo development to leaf senescence. Some of these processes are regulated in interaction with phytohormones, such as auxin. A key interacting factor of T6P signalling in response to the environment is the protein kinase sucrose non-fermenting related kinase-1 (SnRK1), whose catalytic activity is inhibited by T6P. SnRK1 is most likely involved in the adjustment of metabolism and growth in response to starvation. The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway. By inhibiting SnRK1, T6P promotes biosynthetic reactions. This regulation has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.
Answer:Natural selection is a central concept of evolution. The English biologist Charles Darwin and Alfred Russel Wallace, and is sometimes called the survival of the fittest.
Explanation:
the heat they generate wirhin them
<span>The question is asking "Which best matches a list that a scientist would make to describe a forest ecosystem? " An ecosystem is the total of all animals, plants and of the physical enviroment (soil, etc) in a given place. All of these would have to be present in the description, but it would not be possible to expect the list of all the animals - since for example not all of them are known or classified. So the best answer is
A. Different types of animals and plants, and the forest soil</span>
<u>Answer</u>:
The parasite which do all stages of the life cycle (including the hatching of its eggs) occur on the hide of the host animal is (C) Lice.
<u>Explanation</u>:
There are three stages of a lifecycle of a lice: 'egg', 'nymph' and 'adult'. Nits are lice eggs on the head which are confused with dandruff. Egg hatches in around 1 week and release into a nymph. They mature into an adult in 7 days. Adult louse have six legs and can be greyish white in color. They feed on human blood many times in a day. `
For other options like round worms and hookworms, hookworm release eggs and they are released in stool of the dog after few days. This gets mixed in soil and can be consumed by humans as well by exposure. So, these are incorrect options and correct option is lice.
