Answer:
We cannot conclude anything without having more data.
Explanation:
All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data

why us a spirogyra called a thallus ? which types of nutrition does it show ?why?
Explanation:
a plant body that is not differentiated into stem and leaves and lacks true roots and a vascular system. hence spirogyra called a thallus.
Spirogyra is an example of Green algae , thus it prepare its own food by process of photosynthesis in presence of sunlight and chlorophyll.So, its nutrition type is Autorophic.
define and describe osmosis
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.
Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.

PLSSS HELLLPP- Which of the following measurements uses a derived unit? O volume O mass O length O time
Answer:
Volume
Explanation:
volume=length ×length ×length
The metric system is the system used for the measurement. It measures the mass, length, weight, time, etc. The unit of volume is a derived unit. Thus, option A is correct.
What is a derived unit?A derived unit is a unit used to measure and estimate the substance by using the basic or the fundamental metric unit system. It is based on units of the fundamental system.
The fundamental units include mass, temperature, time, luminous intensity, length, electric current, and amount of substance. On the other hand, derived units result from a combination of base units.
A volume is a derived unit as it came from the fundamental unit of length as,
Volume = length × length × length
= cm × cm × cm
= cm³
Therefore, option A. volume is a derived unit.

Why are fungi more like animals than plants?
PLEASE HELP ME
Answer:
Hey mate.....
Explanation:
This is ur answer.....
However, unlike plants, fungi do not contain the green pigment chlorophyll and therefore are incapable of photosynthesis. That is, they cannot generate their own food carbohydrates by using energy from light. This makes them more like animals in terms of their food habits.

In 1970, Frye and Edidin published research describing the mobility of plasma membrane proteins. They fused mouse and human cells together, creating a hybrid cell, and then examined the localization of mouse and human proteins over time. Initially mouse and human proteins were each restricted to one-half of the heterokaryon, but over time the mouse and human proteins mixed, with each being present over the entire cell surface. What technique did Frye and Edidin likely use to examine the mouse and human proteins
Answer:
The answer is "fluorescent microscopy".
Explanation:
A microscope featuring fluorescence is just the same as a conventional light microscope with additional features. Conventional microscopy employs visible light (400-700 nanometers) to illuminate and generate an enlarged image data. Scientists use this highly sensitive, precise, dependable, extensively to see the location of chemicals in tissues and macrophages in organs.

different between dominant character and recessive character
Dominant character:are always expressed when the connected allele is dominant,even if only one copy of the dominant trait exits.
Recessive character:are expressed only if both the connected allele are recessive.
Answer:
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
Explanation:
If some traits are absent or not expressed, but found in the parent, then the allele is said to be recessive.
Difference Between Recessive and Dominant Traits
DOMINANT
Dominant Trait Recessive Trait
Dominant allele is denoted by a capital letter
RECESSIVE
Recessive allele is denoted by a small letter

The Channel Islands are a series of small islands off the California coast. Each island has a genetically distinct population of foxes. Compare the population of foxes on one of these islands to the population of foxes in the forests of mainland California. Which is more likely to be impacted by genetic drift? Which is more likely to be at Hardy-Weinberg equilibrium?
Answer:
The fox population on the Islands experiences genetic drift whereas foxes in the forests has Hardy-Weinberg equilibrium.
Explanation:
The fox population on the Islands experiences genetic drift because there is no chance of introduction of different type of foxes in these Islands which experiences less variation in the population of already existing foxes. Genetic drift is the change that occur in the frequency of an existing gene allele in a population due to random sampling of organisms. Genetic drift may cause gene variants to disappear completely with the passage of time which leads to reduce genetic variation. The foxes that is located in the mainland forest experiences Hardy-Weinberg equilibrium.
A farmer decides to try to increase his profits by mating his two goats that produce the most milk together. The farmer’s descendants continue the process and over 400 years the family produces goats that make more milk than any in the country. Eventually the goats change enough that they are designated a new species. This is an example of:
A. Artificial selection
B. Acquired characteristics
C. Disruptive selection
D. Natural selection
Answer:
A.is the correct answer
Explanation:
People have been doing asimple form genetic enineeringfor thousands of years. This is called selective breeding. Selective breeding, or artifical selection, is a process where people try and improve plants and animals by selecting and breeding those that have desireable charactistics.
For example, a farmer might choose from his two largest cattle in his herd and breed them together so that the offspring will be even bigger and produce more meat.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?
1.A deletion occurred so all of the amino acids added after the mutation may be wrong.
2.An insertion occurred so all of the amino acids added after the mutation may be wrong.
3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.
4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.
Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.
