Which is the correct description for sensory
receptors?
Answer:
Explanation:
A sensory receptor is a structure that reacts to a physical stimulus in the environment, whether internal or external. It is a sensory nerve ending that receives information and conducts a process of generating nerve impulses to be transmitted to the brain for interpretation and perception.
4. While blood contains glucose, potassium, albumin, and chloride molecules, a normal urine sample contains
only potassium and chloride molecules. Why do you thing this is so? (1 mark)
Glucose and albumin (a protein) are too big to pass through the glomerulus therefore they should not be found in normal urine while potassium and chloride molecules are small enough to be filtered through the glomerulus, where it can either be reabsorbed back into the blood or go through the entire tract and be excreted with urine.

why textures in the same sill might vary, with finer grains along the margin and coarser grains toward the middle?
This question is related to the formation of sill through volcanic activity. See the explanation below.
What is responsible for the coarseness of sills?The reason for the variance in the coarseness of grains is the formation of igneous rocks happens deep in the earth and on this surface.
The texture of the sill is dependent on the rate at which it cools.
Coarse-grained sills are formed deep within the earth's crust while the other cool rapidly on the earth's surface.

What percentage of babies have Brown and Blue eyes?
blue=2%
Explanation:
The explanation by the paragraph it is said (to find the percent divide the total number of blue-eyed by the total number of babies born) 20÷10 =2 . The answer is 2%
Answer:
In fact, a 2016 Stanford University study involving 192 newborns found that nearly two-thirds of them were born with brown eyes, while only about 1 in 5 babies arrived with blue eyes. The Stanford researchers also noted, however, that the majority of babies in the study born with blue eyes were Caucasian
Explanation:
Imagine that a lake contains 2 kinds of fish trout and bass 60% of the fish in the lake are bass and 40% are trout if you caught 5 fish at random from this pond which of the following would you expect to catch
You would expect to catch 3 bass and 2 trout.
How lake benefit the survival of fish?Lakes provide an optimum condition for the survival of various fish species. It maintains the level of oxygen throughout. As lakes are not too deep, fishes aquire sufficient oxygen and nutrients for their survival and reproduction.
The percentage of bass is higher as compared to trout, hence out of five, it will definitely have more bass fish.
Therefore, out of five fishes that are caught, 3 of them are bass while 2 are trout.

Where do the tRNA take amino acids?
to the nucleus
outside of the cell
to the ribosome
Answer:
To The Ribosome.
Explanation:
To start, let's review. First off, tRNA means transfer RNA; type of RNA that carries amino acids to the ribosome. An amino acid is a carboxylic acid with an amino group and the building block of proteins. The nucleus is the "brain" of the cell, the control center of the cell, where genetic material (DNA) is found, the nucleus is in charge of everything that happens inside of a cell. The nucleus is the largest and most important part of the cell. Nuclear Envelope. The general purpose of the nucleus is to predetermine and control the production of proteins. It does this by storing the protein code in the DNA, which is hereditary. A cell is the smallest part of a living thing that can carry out the activities needed for life. The ribosome is a cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; consists of rRNA and protein molecules, which make up two subunits. Since we're done reviewing, let's go through the processes of how the tRNA take the amino acids to the ribosome. There are two steps in protein synthesis. They are transcription and translation. During transcription, mRNA (Messenger RNA) is formed in the nucleus of the cell. After mRNA has been made, it leaves the nucleus and goes to the ribosomes in the cytoplasm, where translation occurs. (DNA never leaves the nucleus.) During translation, mRNA attaches itself to the ribosome. Then, tRNA (Transfer RNA) reads the mRNA codons (a codon is a sequence of three nucleotides that code for a protein) and attaches amino acids accordingly. This continues until tRNA reaches a stop codon. Translation is the second phase of protein synthesis. It follows transcription, in which the information in DNA is "rewritten" into mRNA. During translation, the mRNA attaches to a ribosome. Transfer RNA (tRNA) molecules then "read" the mRNA code and translate the message into a sequence of amino acids. Every three nucleotides in the mRNA make up one codon, which corresponds to one amino acid in the resulting protein. The ribosome tracks along the mRNA until it reaches a stop codon, signaling the assembly of mRNA and ribosome to break apart. Protein synthesis is the process where cells create proteins. There are two steps in protein synthesis. They are transcription and translation. During transcription, mRNA (Messenger RNA) is formed in the nucleus of the cell. After mRNA has been made, it leaves the nucleus and goes to the ribosomes in the cytoplasm, where translation occurs. (DNA never leaves the nucleus.) During translation, mRNA attaches itself to the ribosome. Then, tRNA (Transfer RNA) reads the mRNA codons (a codon is a sequence of three nucleotides that code for a protein) and attaches amino acids accordingly. This continues until tRNA reaches a stop codon.

Which action could help a city reduce landfill waste?
A. Building new incinerators
B. Providing plastic trash bags to residents
O C. Downsizing recycling facilities
D. Providing discarded building supplies to residents
Answer: D. Providing discarded building supplies to residents
Explanation:
When these discarded building supplies are provided to residents it keeps these supplies out of landfills, giving them another purpose.
Providing discarded building supplies to residents reduces waste.
What is waste reducing?There are no expenses associated with managing garbage that is never produced, waste reduction (or prevention) is the ideal method of waste management.
Reducing superfluous packaging from manufactured goods and produce is an illustration of waste reduction. Nobody would have to worry about the expense and effort of gathering the surplus packaging, separating it for recycling, disassembling it.
Reducing waste also promotes resource conservation for future generations and a cleaner environment. The following CalRecycle websites might provide you with more information on waste reduction.
