Beak Length in Finches

In a certain population of finches, a single gene controls beak length. There are two possible alleles: S, which leads to a short beak, and s, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype ss will have a long beak, and individuals with the genotype Ss will have a medium-length beak. Scientists measure that in this population of 1,128 total birds, 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks.

Answer: Geographic distributions

Anatomical features

Explanation:

Taxonomy simply refers to the way that organisms are classified and named. Every organism is classified in a particular group which is made up of other organisms that have similar characteristics.

It should be noted that taxonomy, some of the traits that are used to classify species include the geographic distributions and the anatomical features.

In taxonomy, the traits used to classify species include the following:

Geographic distributionsAnatomical features

Taxonomy is the process of classification of organisms based on certain

shared characteristics. These characteristics are usually common

anatomical features shared between them.

Classification and naming of organisms is also based on common

Given an unusual cell with an intracellular fluid containing 10 mM calcium and an extracellular fluid containing 1 mM calcium. If the cell membrane is permeable only to calcium ions, what is the voltage across the membrane? Assume that the system is at equilibrium and at body temperature.

Answers

Answer:

The correct answer is: -31 mV

Explanation:

Given:

Intracellular fluid concentration = 10 mM

Exracellular fluid concentration = 1 mM

temperature = 237+37 = 310 k

Z = 2

F= 96500 C mol-^1

R = 8.314 J MOL-^1K-^1

Formula -

Ex = (RT/ZF) ln ([x]out/[x]in)

= [tex]\frac{8.314*310*2.303}{2*96500} log 10 \frac{1mM}{10mM}[/tex]

= -0.03075447679*1/10 log 10

= - 31 mV

What is the significance of anaphase in this process?

a

Anaphase usually ensures that each daughter cell has the same number of chromosomes as the parent cell.

b

Anaphase usually ensures that each daughter cell has twice as many chromosomes as the parent cell.

С

In anaphase, the cell splits in half.

d

In anaphase, the DNA is being replicated.

Answers

Answer:

a ) Anaphase usually ensures that each daughter cell has the same number of chromosomes as the parent cell.

Explanation:

 Mitosis: After DNI duplication and condensation, Sister chromatids of the chromosome, are held together in the equatorial plane until they reach the Anaphase, during which certain enzymes are activated to break the bonds among them and the separation of the chromatids occur, migrating to the opposite poles.   Meiosis: Gamete formation involves the random and independent segregation of the alleles. After crossing-over, homologous chromosomes which are located in the equatorial plane, get separated. During anaphase I  occur the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair. During Anaphase II, enzymes are activated to break the bonds that keep together the chromosome and separate the sister chromatids.

Anaphase (Mitosis) and Anaphase II (Meiosis) are very similar. By separating sister chromatids, anaphase is responsible that each daughter cell has the same number of chromosomes as the parent cell. Some mutations or alterations in the chromatids migration process might occur during anaphase, such as non-disjunction, which is a defect or mistake in the separation of the homologous chromosomes during anaphase of the meiotic division.  

he following is NOT true about trophic levels: Primary consumers belong to the first trophic level. Secondary consumers belong to the third trophic level. Each stage through which energy travels is called a trophic level. Many species may belong to several trophic levels. Animals capable of feeding at many trophic levels will be able to survive if portions of their food supply are decreased or eliminated.

Answers

Answer:

Animals capable of feeding at many trophic levels will be able to survive if portions of their food supply are decreased or eliminate is not true of about trophic levels

Explanation:

This is because each trophic levels represent energy flow and supply of food to the organisms in the trophic levels. Energy are pass from one tropic levels to another as a result of source of food there. Plants majorly are the primary producers and the primary consumers depend on it. Therefore, if the source of food supply is eliminated in a trophic level, the organisms I'm the trophic level will not be able to survive.

Feedback loops are when the body responds to signals, like insulin, that appear when the balance of something is off. When blood sugar is too high, insulin signals the liver to absorb more blood sugar, returning it to normal. When blood sugar is low, glucagon signals the body to release stored glucose to raise blood sugar back to normal.

Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.

A. As mass increases, volume increases

Explanation:

The table in the image attached is depicting the relationship between the mass, volume and density of a certain metal A. Ideally, the density of a substance is directly proportional to its mass, and indirectly proportional to its volume.

However, based on the data provided on this table, the MASS (g) increased as the VOLUME (mL) increased and vice versa. The highest mass of 10.10g has a volume of 3.8mL. This value of volume decreased with decreasing mass. Hence, based on the information of the table, as mass increases, volume increases.

involves accumulation of rhodopsin

Explanation:

This is because dark adaptation is the ability of the eye to react to low light sensitivity and all the rod pigments of the eye bleached out which is as a result to the bright light and this make the rods nonfunctional in the initial state . Once you are in the dark, rhodopsin regenerates and tthis lead to increase in retina sensitive continuously.

what are three ways mutations can occur
I will give brainlest answer​

Answers

The three ways mutations can occur are
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
DNA is a long polymer of nucleotides (long strand of A,T,G,C in a defined sequences for any given gene.

The three types of mutations are 1. Substitution where a base is changed from its original to a new base (A—>G) 2 insertion where a nucleotide is added into the DNA. 3 Deletion where a nucleotide is deleted.

1 substitution 2. Insertion 3 deletion
