In silkmoths, red eyes (re) and white-banded wings (wb) are encoded by two mutant alleles that are recessive to those that produ

ce wild-type traits (re and wb ); these 2 genes are on the same chromosome. A moth homozygous for red eyes and white-banded wings is crossed with a moth homozygous for the wild-type traits. The F1 have wild-type eyes and wings. The F1 are crossed with moths that have red eyes and white banded wings in a test cross. The progeny of this test cross are: 418 wild-type eyes, wild-type wings 19 red eyes, wild-type wings 16 wild-type eyes, white-banded wings 426 red eyes, white-banded wings

Answer:

Question 1

D

Question 2

C

Question 3

D

Explanation:

1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.

Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)

2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.

A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)

3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.

Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)

maw [93]

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

What is it about a person that could cause ordinarily beneficial traits to become so self-defeating?.
Gala2k [10]

You may have feelings of inadequacy when you can't have—or give your children—the kind of life that others seem to have. All of these situations and challenges can lead to stress, which in turn lead to the development of Self Defeating Behaviors (SBD).

<h3>What is  beneficial traits?</h3>
  • Beneficial traits are extremely varied and may contain anything from protective coloration to the ability to operate a new food source, to a change in size or constitution that might be useful in a certain environment.
  • Over time, these favorable traits become more common in the residents. Through this process of natural preference, favorable characteristics are transmitted through generations. Natural preference can lead to speciation, where one species gives rise to a new and distinctly different species.
  • The artificial section is the identification by humans of seductive traits in factories and animals, and the steps taken to enhance and memorialize those traits in future years.
