1. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
2. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
3.Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems. (Not from google )
Answer:
1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.
Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.
Lymph eventually ends up in the circulatory system.

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem
Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.
Explanation:
hope it helps :)
The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:
The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.
The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.
The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.
The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.
Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.
In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.
On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.
Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA : T C G A C A
Answer: thymine (T) Cyostine (C) guanine (G) adenine (A)
Explanation:
Guanine (G) is complementary to cytosine (C), and adenine (A) is complementary to thymine (T). Hence, the nitrogenous bases that would form for the DNA bases TCGACA are AGCTGT.
How does base pairing take place in DNA?
A DNA double helix is joined together by the hydrogen bonds that are formed between the nitrogenous bases in the opposite strands. Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) are the nitrogenous bases present in the DNA. Both adenine and guanine are purines. They make bonds with pyrimidine.
Adenine (A) of one DNA strand makes a double bond with Thymine (T) of the opposite DNA strand. The guanine (G) of one DNA strand makes three hydrogen bonds with the cytosine (C ) of the opposite DNA strand. As there are three hydrogen bonds present in guanine and cytosine (GC), they require more energy to break the bond. Adenine and thymine (AT) have two hydrogen bonds, hence they require less energy than GC bonds.
Hence, in a DNA strand, the complementary strand of TCGACA is AGCTGT.

A. sweating
B. burrowing underground
C. taking in more calories
D. wearing a jacket
Answer:
A. Sweating
Explanation:
I just took it <3
The option which is an example of an automatic regulatory reaction is: A. sweating
Automatic regulation can be defined as a biological process that occurs within many living organism due to the function of an internal adaptive mechanism that typically works to mitigate (lessen or adjust) its system's response to stimulus.
Generally, the body organs and system that are considered to carry out some degree of automatic regulation are:
The brain.The heart.The kidney.Hence, an automatic regulatory reaction is a biological process that happens in response to other bodily process and stimuli.
For instance, the nervous system produces an automatic regulatory reaction to emotions (fear), illness and heat such as sweating.
Sweating is an automatic regulatory reaction of the human body to protect and mitigate the effects of an extreme change in temperature (heat).

What is electronegativity?The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.
American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.
Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.
Therefore, Zinc 1.65, Chromium 1.66, Tungsten 2.36 and Iodine 2.66.
