Classify each planet as an inner planet or an outer planet.
how is the mitochondrial DNA (mtDNA) transferred from generation to generation.
Answer:
maternal mtDNA
Explanation:
While nothing but the haploid nucleus remains of the sperm during fertilisation, the ovum still has its mitochondria and other organelles. Mitochondria are capable of division and will divide according to cell's needs.
So it is the maternal mtDNa that gets passed on. Spontaneous mutations can happen at any point ofcourse and get passed on in the same way.

Answer:
Wind energy is one of the most commonly used types of renewable energy. and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren’t capable of generating electricity 24/7. Unlike coal, natural gas, or oil, generating electricity from wind doesn’t result in greenhouse gas emissions. While there are some environmental considerations that come with building large wind farms, once operational, wind turbines themselves don’t require burning any fossil fuels to operate.
Additionally, wind energy is completely renewable and will never run out. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we don’t have to worry about supply issues in the future.
As far as upfront costs go, wind farms or individual turbines can be expensive to install. However, once up and running, operating costs are relatively low; their fuel (wind) is free, and the turbines don’t require too much maintenance over the course of their lifetime.
A wind turbine’s effectiveness in generating electricity depends on the weather; thus, it can be difficult to predict exactly how much electricity a wind turbine will generate over time. If wind speeds are too low on any given day, the turbine’s rotor won’t spin.
This means wind energy isn’t always available for dispatch in times of peak electricity demand. In order to use wind energy exclusively, wind turbines need to be paired with some sort of energy storage technology.
One of the biggest downsides of wind energy is the noise and visual pollution. Wind turbines can be noisy when operating, as a result of both the mechanical operation and the wind vortex that’s created when the blades are rotating. Additionally, because wind turbines need to be built up high enough to capture a good amount of wind, the turbines can often interrupt otherwise scenic landscapes, such as mountain ranges, lakes, oceans, and more.

12. Nitrogen flows from producers through levels of consumers
13. How does water from the atmosphere return to Earth's surface?
14. What would happen to the ecosystem if there were no nitrogen-fixin bacteria?
Answer: All organisms need energy. ...
Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. ...
Heterotrophs (consumers) obtain energy by consuming other organisms. ...
The flow of energy in an ecosystem can be represented with a food chain or food web
Explanation: A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. A consumer is an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources. Consumers are also called heterotrophs, or other-feeders Producers
Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react 4these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.

How can students in the photograph use the net to sample the invertebrates in the river.
Answer and Explanation:
Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.
There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.
Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.
Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.How do you think Nucleic Acids and Proteins work together in the body? Why are they both important to humans?
Explanation:
protein is the element responsible for building up of cells and the nucleic acid is embedded in the cell, so protein builds the whole cell including the nucleic acids.. the nucleic acid is also packed by histones which is a proteinous structure. both are important because, in the cell all organelles require protein for their growth and likewise the encoding of the genetic information carrier

In the Hershey Chase experiment components of bacteriophages were labeled with radioactive isotopes of sulfur and phosphorus What was
the Hershey-Chase evperiment designed to determine?
Answer:
c
Explanation:
It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.
What was Hershey-Chase experiment?The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.
In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.
The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.
