Suppose that to snow leopard’s, heterozygous for both traits meet. Suppose further that in the female, the two dominant alleles are on the same chromosome of the homologous pair, while in the mail, each chromosome of the pair has one dominant and one recessive allele. What is the expected phenotypic ratio of their children?
Complete question:
Snow leopards live in the high reaches of the Himalayas and have several adaptations to deal with living most of the time in snow. They have wide paws with hair between the toes to allow them to run on top of the snow crust. Assume that wide paws (W) and hair between the toes (T) are both dominant traits and are on the same chromosome. Suppose that two snow leopards, heterozygous for both traits, mate. Suppose further that in the female, the two dominant alleles are on the same chromosome of the homologous pair, while in the male, each chromosome of the pair has one dominant and one recessive allele.

Biologists have been able to keep isolated chloroplasts or
mitochondria for a few hours or days. can these structures be
considered alive?
Answer:
Isolated chloroplasts or mitochondria cannot be considered alive, because although they can survive while isolated for a few hours or days and they resemble that of an independent cell (which are alive), they don't metabolise energy, and they don't have cells.

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
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.

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?
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!

Genotypes of offspring:
Phenotypes of offspring:
Plz help me
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:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.
What controls the timing of The Great Migration?
Answer:
The best time to see the Great Migration is during the dry season, between July and early October. It's warm, weather is stable, and animals are abundant. The sparse vegetation and dried-up waterways force the animals to head up north to find food and drink.

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.
Examples Sea Horse, Gold fish, Eel etc
_____________________________________[tex]\huge\text{Similarities}[/tex]They have gill to breath Streamlined body to move in fast moving water All fishes are cold-blooded.

How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

With regard to iodine, which is hypertonic? [beaker/ tube]
With regard to starch, which is hypertonic? [beaker/ tube]
Needs to be in within a few hours, please help
Answer:
With regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.
Explanation:
The beaker has higher amount of iodine solution than the tube so the beaker is considered as hypertonic solution while on the other hand, the tube has more starch concentration than the beaker so the tube is considered as hypertonic solution. In hypertonic solution, the concentration of solutes are higher than the surrounding environment or another solution. So that's why with regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.

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
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.
