Answer:
Human activities affect the flow of energy and matter in an ecosystem and alter the energy balance in ecosystems through the unsustainable nature of what they do. The energy flow is affected in several ways as a result of pollution, overpopulation, deforestation, burning fossil fuels, etc. Such changes have stimulated soil erosion, climate change, causing water unfit to consume, poor quality of air and so on. When humans cause a change in the energy balance, they impact the ability of the ecosystem to respond and adapt to changes in the environment. It is like getting a cut, but it never heals and grows bigger instead.
Answer:

Explanation:
they pollute water take up the extra space and disturb the animals and their homes

When you performed BLAST search for a DNA sequence, which description is correct for “Identity value”?
a) Identity value is the number of matched nucleotide letters.
b) Identity value is the proportion of matched nucleotide letters among total size of the sequence.
c) Identity value is an estimated p-value from BLAST algorithm
d) Identity value is the number of unmatched nucleotide letters.
Answer:
the answer there is C and I also think it is
The option (C) is correct. Identity value is an estimated p-value from BLAST algorithm.
What is BLAST?In bioinformatics, BLAST is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.
Moreover, BLAST is a computer algorithm that is available for use online at the National Center for Biotechnology Information (NCBI) website, as well as many other sites. BLAST can rapidly align and compare a query DNA sequence with a database of sequences, which makes it a critical tool in ongoing genomic research.
Hence, BLAST is a sequence similarity search tool, and it calculates an E-value and a bit-score to assess the quality of each match. An E-value represents the number of hits of equal or greater score expected to arise by chance.

Looking at the model above, if the hawks are increased, what will happen to the
grass? Please explain your reasoning
If the hawks are increased in this model, the grass will increase in the food chain.
What is a Food chain?This is defined as the sequence of transfers of matter and energy in the form of food from one organism to another.
When hawks are increased, the primary consumers will decrease which are the ones who eat the grass. This will therefore lead to an increase in the grass population.

Which activity is directly regulated by neurons?
Neurons are the part of the nervous system that transport the signals. The neurons regulate the localization of several proteins at the nerve terminal.
What is the neuronal activity?Neurons are the electrically excitable unit of the nervous system that play a major role in the neuronal circuit. It also takes part in the localization of proteins, other molecules, and receptors.
The activity controls and balances the synaptic stability, and the rate of the synapse formation that occurs in the dendrite and the body of the nerve cell.
Therefore, the neurons direct the localization of the proteins.

A saw mark in bone made by a small-toothed power saw will have:
Group of answer choices
very smooth walls with fine striae of the same orientation
uneven walls with striae in multiple directions and a breakaway spur
likely multiple large kerfs from the saw bouncing, striations are oriented chaotically
none of the above
A bone saw mark made by a small-tooth power saw will have very smooth walls with fine striations of the same orientation.
Effect of a bone cut by electric saw?This process causes minerals (mainly calcium) to be deposited in the part of the bone that is undergoing pressure. Therefore, the piezoelectric effect increases bone density. Piezoelectric surgery is a technique that uses ultrasonic vibrations to perform osteotomies.
With this information, we can conclude that a bone saw mark made by a small-tooth power saw will have very smooth walls with fine striations of the same orientation.

An element has an atomic mass number of 16 and an atomic number of 7. what is the elements protons and neutrons?
Answer:
7 protons, 7 neutrons (READ EXPLANATION)
Explanation:
The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.
However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.
