Answer:
An endangered species recovery plan is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes.
Explanation:
When recovery plans are carried out well, they do not simply act as stop gaps to prevent extinction, but can restore species to a state of health so they are self-sustaining. There is evidence to suggest that the best plans are adaptive and dynamic, responding to changing conditions. However, adaptive management requires the system to be constantly monitored so that changes are identified.[10] Surprisingly this is frequently not done, even for species that have already been red listed.[11] The species must be monitored throughout the recovery period (and beyond) to ensure that the plan is working as intended. The framework for this monitoring should be planned before the start of the implementation, and the details included in the recovery plan. Information on how and when the data will be collected should be supplied.
help would be appreciated.

- cells are found in every living thing
- cells are not limited to only a particular size, they have various size and shapes, this is because each cell perform a specific function and as such, they tend to have a different sizes
- cells are considered the basic structural unit of all living things, both plants, and animals, they both depend on cells to survive
- cells are found in every living thing(plants and animals) they perform vital functions

Sam has a mutation in a gene that affects the function of a transfer RNA (tRNA). Human cells have 20 different types of tRNAs, and each adds a different amino acid to growing peptide chains, which form proteins. Based on what you know so far, would you expect this mutation to affect all proteins produced in Sam's cells? Explain your reasoning.
Answer:
No
Explanation:
The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.

precautions for soil sampling
Answer:
Explanation:
When collecting samples, avoid small areas where the soil conditions are obviously different from those in the rest of the field—for example, wet spots, old manure and urine spots, places where wood piles have been burned, severely eroded areas, old building sites, fencerows, spoil banks, and burn-row areas.
Read each of the sentences that describe a phase of meiosis. Place each sentence into the correct box.
Answer:
Prophase1-crossing over may occur between the non-sister chromatids
Metaphase1- Homologous chromosomes line up at the center of the cell
Anaphase and telophase 1- homologous pairs separate and move towards opposite ends of the cell, Nuclear membrane forms and cytokinesis follows.
Meiosis 2- haploid number of duplicated chromosome line up…
Sister chromatids separate and become daughter…
Four haploid daughter cells are formed….
Explanation:
Meiosis I
P-I: Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs
M-I: Spindle fibres from opposing centrosomes connect to bivalents (at centromeres) and align them along the middle of the cell
A-I: Spindle fibres contract and split the bivalent, homologous chromosomes move to opposite poles of the cell
T-I: Chromosomes decondense, nuclear membrane may reform, cell divides (cytokinesis) to form two haploid daughter cells
Meiosis II
The second division separates sister chromatids (these chromatids may not be identical due to crossing over in prophase I)
P-II: Chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles (perpendicular to before)
M-II: Spindle fibres from opposing centrosomes attach to chromosomes (at centromere) and align them along the cell equator
A-II: Spindle fibres contract and separate the sister chromatids, chromatids (now called chromosomes) move to opposite poles
T-II: Chromosomes decondense, nuclear membrane reforms, cells divide (cytokinesis) to form four haploid daughter cells
The final outcome of meiosis is the production of four haploid daughter cells

The oceans are primarily composed of which two elements?
Carbon and hydrogen
Calcium and silicon
Hydrogen and oxygen
Nitrogen and phosphorus
Answer:
hydrogen and oxygen snsnsn
The oceans are primarily composed of carbon and hydrogen elements.
What are elements?An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.
The six elements found in all organisms are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur; collectively called biological elements and shown as the acronym CHNOPS. These elements can bond with each other as well as other elements to create molecules.
Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.
The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
The wedge works on the principle of an inclined plane.
The Door Stop Is an example of one,

Explanation:
A Paramecium (a single celled organism) swims into an area of salty water.. The Paramecium shrivels up as it loses water through its cell membrane. Explain what happened.
The paramecium lost water and shrank as a result of the water within being drawn to the high concentration of salt outside and moving through the cell membrane. This was due to osmosis.
What is osmosis?
Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.
Any solvent, including gases and supercritical liquids, can go through the osmosis process.
When solute concentrations inside and outside of the cell are equal, an isotonic solution has been created. When the concentration of solutes outside the cell is higher than within, the solution is said to be hypertonic. When the concentration of solutes inside the cell is higher than outside, the solution is said to be hypotonic.
Therefore, the high concentration of salt outside attracted the water inside the paramecium, which migrated through the cell membrane and caused the paramecium to lose water and shrivel.
