Answer:
The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and long-term regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes

certain cells have densely packed mitochondria and the cristae ( infolded projections of a mitochondrion) are very closely together. what would you predict about the function of such cells? explain your reasoning
Answer:
What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.
Explanation:
Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.
A cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high.
An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.

If someone stole your DNA, could they steal your identity?
Yes
Criminals might steal DNA to use the genetic identity of their victim
Answer:
yes and no
Explanation:
if someone actually stole your DNA you wouldn't be alive right now,
but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

DNA contains genes that can be read to create------------------
that directs the ribosome to build certain--------------------
as needed by specific cells or situations.
Answer:
DNA contains genes that can be read to create messenger RNA that directs the ribosome to build certain proteins as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
When a cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized.
Which of the following types of the cell transport moves from low to high concentration and requires energy
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

The cartilage that connects bones together belongs to which system?
Group of answer choices
skeletal
muscular
nervous
integumentary
Answer:
skeletal system
Explanation:
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.

Which of the following statements is true?
Groundwater is not part of the water cycle.
Most of the earths water is freshwater.
Thermal pollution is the main disadvantage of hydroelectric power.
Refining oil pollutes the air with nitrogen dioxide.
Answer:
Im pretty sure that "Refining oil pollutes the air with nitrogen dioxide" is a true statement.
Explanation:
well,,, all the others are false because: groundwater is definitly part of the water cycle, most of earth's water is NOT fresh bc only 2% of earth's water is fresh, and hydroelectric power would contribute more to water pollution than to thermal pollution-

Which of the following molecules is an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms?
a.) Saturated fatty acids
b.) Unsaturated fatty acids
c.) Fructose
d.) Glucose
Answer:
B
Explanation:
Unsaturated fatty acids have kinks in the fatty acid chains. Every double bond is a kink.
Unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.
What do you mean by Molecules?Molecules may be defined as one or more groups of atoms held together by various chemical bonds.
On the basis of the number of bonds, fatty acids are classified into two categories, i.e. Saturated and unsaturated fatty acids.
Saturated fatty acids consist of only a single bond with long carbon chains with terminal carboxylic acid, while unsaturated fatty acids consist of double or triple bonds with long carbon chains with a terminal carboxylic acid.
Therefore, unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.

In the exhaustion stage of the general adaptation syndrome, the parasympathetic division of the autonomic nervous system may predominate. As a result, __________.
Answer:
many aspects of sympathetic activity are reversed
Explanation:
When he parasympathetic division of the autonomic nervous system predominates, this may result into many aspects of sympathetic activity being reversed. The sympathetic nervous system, which is like the accelerator of the body, is known as the flight or fight nervous system and deals with stress, typically speeding things up. The parasympathetic nervous system, which is like the brakes of the body, helps to conserve energy and protect, typically slowing things down.
