Answer:

Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.

Explanation:

Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.

The cross can be represented by a Punnett Square:

Bb X Bb cross

alleles     B    b

B             BB Bb  

b             Bb bb

Where the result is:

Genotypes:  

Phenotypes:

In this case, the probability of having brown or red feathers is 3:1.

Answer:

False

Explanation:

The above statement is false

False because reflexes and snap reactions are generally bounced back directly from the spinal cord to save time. An example could be touching something hot because you react and move away instantly rather than your body burning for a second while the brain processes the information.

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).

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).

Answer:

The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.

Explanation:

As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

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!

Explanation:

The study of specific characteristic and mechanism of animals or plants that makes it to exits living organisms is called physiology. Thus this could be plant, animals insects physiology.

In 1628 Harvey for published a book, titled An anatomical exercise on the motion of the heart and blood in living beings.  That was  the first time the word physiology was used.

He used the tam to  distinguish between natural and supernatural causes of things in the book.

[tex]\Huge\text{Pisces or Fishes}[/tex]

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:

[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.

Examples Sea Horse, Gold fish, Eel etc

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.

The correct answer is - prokaryotic and unicellular.

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.

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

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.

Answer:

False.

Explanation:

All of the things found in the Earth system can be categorized into four (4) main categories and these includes;

I. Land: this subsystem forms a sphere which is generally referred to as litosphere.

II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.

III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.

IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.

If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.
