Quail use feathers for thermoregulation, flight and camouflage. What type of adaptation are feathers?

A. Structural
B. Behavioral
C. Physiology
D. Feathers are not an adaptation

Answers

Answer 1

Answer:

structural

Explanation:

In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS

Answers

Answer:

C. BbSs

Explanation:

The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.

This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.

So, the genotype must be C, BbSs

The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.

The parent's genotype will then be BbSs.

The genotype of both parents have to be heterozygous as a result of the

presence of its forms in the B and S traits. There is the presence of the

dominant (B,S) and recessive traits (bs).

The genotypes of the parent will however have both traits in them which

translates to the option C) BbSs being the most appropriate.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants with wrinkled seeds.

What was a conclusion Mendel drew from the F1 generation of this cross?

Answers

Explanation:

Traits are inherited in discrete units, and are not the results of "blending." ... traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.

Answer:

The dominant factor, or allele, is for round seeds.

Explanation:

The factors (or alleles) don't disappear when two species are crossed, so "the factors or alleles for round seeds disappear completely from the plants" and "the factors or alleles for wrinkled seeds disappear completely from the plants" are both incorrect. From the drawing, we can see that the F1 generation is a round seed, meaning the dominant factor is for round seeds. Hope this helps!

What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?

ts fossil records but i need an explination

Answers

Answer:

Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.

Explanation:

A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.

If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

Explanation:

Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.

These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?

Answers

Answer: The removal of portions of RNA known as intervening sequences (introns)

Explanation:

The removal of portions of RNA is known as intervening sequences (introns).

What is the process of splicing?

In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.

Intron sequences are cut out and exon sequences are joined during the splicing process.

As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.

In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.

Therefore, the removal of portions of RNA is known as intervening sequences (introns).

Pisces or Class Fish is the largest group of chordates which includes 25000 species of fishes. Study of fishes is called Ichthyology.

Fish is an aquatic gill breathing gnathostomates whose stramlined body is provided with paired fins and covered over dermal scales.

Super Class pisces is divided into two classes:

Chondrichthyes Osteichthyes _____________________________________

[tex]\Huge\textbf{Chondrichthyes}[/tex]

Chondrichthyes are Cartilagineous fishes. This class is also called Elasmobronchi. It has exclusively marine fishes with endoskeleton made of cartilage. Their skin has tiny shark enamel coated denticles called Placoid Scales. They are heterocercal and Mouth is present at ventral to tail fins. They have exposed 5 gills on each sides.

Example Shark, Ray fishes, Dog dish etc

_____________________________________

[tex]\Huge\textbf{Osteichthyes}[/tex]

These fishes are Bony Fishes. This group is also called Teleostomi, They are found in both marine and fresh water. Their endoskeleton is made up of bones. Their skin has thin bony plates called cycloid or ctenoid. Their gills are covered with outer skin called operculum. Tain fin is homocercal and mouth is present at anterior tip.

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?

Answers

Answer:

The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.

Explanation:

Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.

Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.

Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
