what are some negatives and some positives of coastal development?
Answer: Positive: Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
Negative: Added to this are impacts such as increased erosion due to coastal development, increased pollution, and increased boat traffic - all of which lead to further habitat loss and put increased pressure on marine species. ... Other coastal developments can also harm sensitive marine habitats and species.

Why do we calculate calories per gram instead of just calories?
Because an amount of the said substance emits a specific amount of heat.
In food usually calories are measured per 100 grams.
For biomolecules calories are measured per 1g (e.g. 1g glucose=4.1kcal)

WOULD THERE BE ANY BACTERIA
IN AN AQUARIUM?
A balanced

you make out in the
aquarium shown here ? Name

.............
...............
Do you think there would be
some bacteria in it? If so, in
which part of the aquarium
would they be occurring in
abundance and what for?
.................
Answer: yes, many different kinds
Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.

A lever is one of the types of simple machine. It is used to rotate on a fixed point. Load, effort and fulcrum are the three important parts involved in the functioning of lever. In the first class lever, the fulcrum is situated in the middle of the load and the effort. In the second class lever, the load is situated in the middle of the fulcrum and effort. In the third class lo=ever, the effort is situated in the middle of the fulcrum and the load.

In your own words, explain why the landscape of Florida has not changed over time like that of Colorado.
Answer:
The landscape of Florida has not changed over time like that of colorado because the rock structures of colorado are much older than that of florida. Colorado also experiences a lot of tectonic plate movement. This led to the colorado river flowing through it and through weathering and erosion the landscape changed. Florida is not affected by the same things so the landscapes change in different pace
The landscape of Florida has not changed over time like that of Colorado because Colorado is a frigid mountainous area while Florida has a humid subtropical climate.
What do you mean by Landscape?The landscape of an area may be defined as the representation or visible region of a defined area that is set up by artificial boundaries.
The region of Colorado experiences the movement of tectonic plates that changes the area of river flowing which leads to the activities like weathering and erosions.
While Florida experiences a hot and humid climate with stable conditions. Hence, the change in landscape is not rapidly seen in Florida.
Therefore, it is well described above.

What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones

Why would a certain trait have a
lower fitness than another causing
that trait to die off in a certain
population?
A. The trait has been around too long to be useful.
B. The trait does not benefit or hinders the
organism.
C. The trait does not wish to be passed on.
Answer: B
Explanation: Traits usually die off when they are unneeded by the organism, or if the trait causes harm to the organism's survival. Through natural selection, over time, the organisms with the best combination of traits for its survival will become the dominating species, and those with weaker traits may not survive long enough to pass off their traits to future offspring.
