The white winter coat blends in with the snow during the winter. Similarly, the coat changes to brown once it is summer so that the white coat doesn't stick out.
A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:
• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.
Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.
Answer:
Cream and brown lizards can be true-breeding, but golden lizards never breed true.
Explanation:
What part of the cell determines the type and order of the amino acids that make up a protein?
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.

When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification portion below, the definition of the topic is mentioned.
Explanation:
This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic. These are assumed that understand the connection to a specific community follow these rituals only to solve difficulties they have previously faced due to errors perpetrated by certain ancestors.1.Gravity is

Answer:
The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.
Explanation:
consider the endosymbiont theory and the fact that chloroplasts contain dna molecules. given that chloroplast DNA has genes,
Answer/Explanation:
The endosymbiotic theory is the idea that eukaryotic cells evolved from the fusion of two prokaryotic cells that formed a symbiotic relationship, with one living inside the other.
An endosymbiont is one organism that lives inside another one.
The existence of mitochondria and chloroplasts, which contain their own DNA and ribosomes, supports this theory. Mitochondria are chloroplasts were once free-living organisms, they were prokaryotes that ended up inside of other cells.
Mitochondria and chloroplasts have genes that are very similar to the genes of prokaryotes. Their membranes look like the prokaryotic cell membrane, and they divide in similar ways.

what role does energy play in changing particle motion?
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
Explanation:
Which statement best describes the initial process of N-linked glycosylation in the endoplasmic reticulum
Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
