What organism is widely known for its importance to Darwin’s work? Why?
Answer:
Darwin's work in particular focused on animals of the Galapagos islands, especially finches. Over time, the idea that species changed from natural selection pressures through “descent with modification” gave rise to the idea of evolution.
Darwin was also interested in Phytophthora, the widely dispersed plant pathogen, and the attempts to grow Phytophthora-resistant plants, and was fascinated by the many algae he encountered on his voyage1.
Explanation:
and this helps him to develop the theory of natural selection

My organism is called the Red Panda (Ailurus fulgens). It is a mammal native to the eastern Himalayas and southwestern China. The Red Panda is the only living species of its genus, Ailurus, and is closely related to the Giant Panda, although it has a much more specialized diet. It is an excellent climber and has a thick, woolly coat to help keep it warm in its cold mountain habitat.
The Red Panda has evolved over time to become more specialized in its diet and habitat. Its thick fur helps to keep it warm in the cold mountain environment, while its long, bushy tail helps it balance while climbing trees. Its diet consists mainly of bamboo, but it also eats fruits, eggs, and small animals. Its sharp claws and teeth help it to break open bamboo stalks and to defend itself against predators. Is it living now or extinct?

What are two similarities and two differences between
grouper and bluefin tuna aquaculture.
Similarities:
Grouper and bluefin tuna are both highly valued meat species that are extensively grown in aquaculture.Floating cages or pens are commonly used to farm both species in coastal marine habitats.Differences:
Because grouper develop more slowly and require more room, they are often farmed at lower numbers than bluefin tuna.Bluefin tuna are often farmed using a process known as "fattening," which involves catching the fish at an early age and raising them in captivity until they reach market size, whereas grouper are typically farmed from juvenile fish until they reach market size.The following behaviors help birds increase their reproductive success in different ways. Which one most directly increases a bird’s chance of mating?
Choose 1 answer:
(Choice A)
A male peacock shows off his large, colorful tail feathers to attract a female.
(Choice B)
Downy woodpecker parents bring their offspring food until the offspring are ready to leave the nest.
(Choice C)
A bald eagle eats a large amount of prey that it will digest over a period of a few days.
A male peacock shows off his large, colorful tail feathers to attract a female directly increases a bird’s chance of mating. So, the correct option is (A).
What is Mating?Mating is defined as the pairing of opposite-sex or hermaphrodite organisms for the purposes of sexual reproduction where fertilization is the fusion of two gametes. Insemination is the union of the sex organs of two sexually reproducing animals for conception and subsequent internal fertilization.
The male is attracted to the female usually by chemical attraction, the release of pheromones, then the male grabs the female, adjusts to the mating position, and finally transfers a package of sperm, the spermatophore, to the female. and attaches. In such a situation, the male peacock attracts the female by spreading its colorful feathers.
Thus, a male peacock shows off his large, colorful tail feathers to attract a female directly increases a bird’s chance of mating. So, the correct option is (A).

25%, female only
50%, male or female
50%, males only
75%, male or female
The probability that they will have an offspring who is color-blind and which gender could be afflicted is 50% males only.
What is colorblindness and how does it occur?Normal vision is represented by (XX), and colorblindness by (XX) (XX). The letter X denotes the sex-linked recessive gene for color blindness. If a colorblind guy (Y) marries a normal lady (XX), all male progeny (sons) will be born in the F 1 generation (XY).
The female progeny (daughters) will have a normal phenotypic, but they will be heterozygous genetically (XX). These girls are carriers of the condition because they have the recessive gene for color blindness.
If a carrier woman with normal vision (heterozygous for color blindness) marries a normal male (XY), the F 2 generation may have the following progeny: 50% of the girls are normal and 50% are carriers for the disorders; 50% of the males are colorblind and 50% have normal vision.
As a result, all sex-linked genes transfer from male to female and then back to a male of the F 2 generation (grand-children generation). That is, one in every two (50% or 0.5) of her grandson is colorblind.
Hence, 50% males will be affected.

In pea plants, round pods are dominant to wrinkled pods. If a heterozygous round pea plant is crossed with a homozygous round pea plant, what percentage of the offspring will be homozygous round
Pls help！
100% of the offspring will be homozygous round in this cross.
What is a homozygous?
A homozygous round is an organism that has two identical copies (alleles) of a particular gene that codes for the trait "round." This means the organism will always express the round trait, regardless of the environment or the presence of other alleles.
This is because the round pea plant that is heterozygous still carries two copies of the round gene. When it is crossed with a homozygous round pea plant, all of the offspring will have two copies of the round gene, making them homozygous round.

In complete dominance the dominant allele inhibits the expression of the recessive allele. Genotypes with at least one dominant allele (homozygous dominnat or heterozygous) express the dominant phenotype. Option C) Rr x rr
What is complete dominance?Complete dominance is the inheritance pattern in which one of the alleles hides the expression of the other allele.
The dominant allele inhibits the recessive allele when together in the same genotype (heterozygous individuals), and only the dominant phenotype can be expressed.
The recessive allele can only express in an homozygous recessive genotype.
In the exposed example, let us assume the phenotype round seeds is dominant over wrinkled seeds. Let us also assume that this feature is coded by a diallelic gene that expresses complete dominance, in which
R is the dominant alleler is the recessive alleleAccording to this information and the phenotypic ratio among the offspring, we could assume that
The plant with wrinkled seeds is homozygous recessive because it expresses the recessive phenotype, rr.The genotype of the plant with round seeds might be either homozygous dominant or heterozygous, because it expresses the dominant phenotype.If this plant was homozygous dominant, the whole F1 should have round seeds because this plant can only provide dominant alleles to the progeny.
If it was heterozygous, the F1 plants can have either round seeds or wrinkled seeds, because this parental plant can provide a dominant and a recessive allele.

How does gravity explain our observations of pattern in space?
The General Theory of Relativity explains the effects of gravity on space and time by proposing that gravity is not a force, but rather a distortion of space-time. This means that mass causes space-time to curve or warp, and objects travel along the curved paths.
What is force?Force has been an interaction between two objects which has been results in the change in the motion of the objects. It has been a vector quantity, meaning it has both magnitude and direction.
Force can be used just to push, pull as well as twist objects. It can be used to lift, along with the move and accelerate objects. Force can also be used to create energy and is an important part of mechanics.
