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.

d. carbohydrates

Explanation:

The products of this equation actually belong to carbohydrates.

Carbohydrates are known to be a large group of organic compounds which is seen in foods and living tissues. Carbohydrates usually contain hydrogen and carbon and are in the ratio 2:1. When broken down, it releases energy which animals use for work.

Two known common carbohydrates are the starch and cellulose. They are macromolecules and are also polymers. Their monomers are units of sugar (glucose). Carbohydrates have the general molecular formula Cm(H2O)n (where m and n represent numbers).

A body is made of matter and matter is made of very small particles called molecules, which are constantly moving.

The molecules in a cold body move little but in a hot body they move more because we have provided heat.

When a hot body comes into contact with a cold body these things happen:
1) the hot body cools down (becomes cold).
2) the cold body heats up (gets hot).
3) both bodies reach the same temperature.

In summary, the heat passes from the hottest body to the coldest body until thermal balance is reached (the two bodies reach the same temperature).

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.

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.  

Why is the normal range for the mass of DNA in a male cat cell lower than for a female cat?

Answers

Females have two X chromosomes. And males have an X and a Y chromosome. The Y chromosome in males is shorter than an X chromosome. Because the size of the y is less than the size of the X there is less nucleotides that making up the dna of the chromosome. (A chromosome is condensed Double strand DNA)

why do orangutans need so much space?

Answers

Answer:

Orangutans are the heaviest tree-dwelling animal

They spend most of their lives swinging through the canopies and need vast stretches of forest to find enough food and mates. Deforestation and hunting are the biggest threats to orangutans.orangutans need so much space because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas.Orangutans have large home ranges, which may overlap. Each adult female usually lives in a stable home range of about 3.5 square miles (9 square kilometers). An adult male's territory may be up to 15 square miles (39 square kilometers).

Explanation:

hope this helps have a good rest of your day :) ❤

Answer:

in botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.
