Marine iguanas are large lizards that live in the Galápagos Islands. They feed on algae growing on rocks at the edge of the sea. When an El Niño event occurs, the sea around the islands becomes warmer, and the algae do not grow as rapidly as they do during typical temperatures. Scientists studied the relationship between the size of male iguanas on one of the Galápagos Islands and their survival during typical temperatures or during and El Niño event. The data are shown in the graph. Based on the data, identify which size make iguanas are most affected by an El Niño event and explain the most likely cause for this size of male iguana to be affected more than other sizes.

Answer:Likely option 1

Explanation:Natural selection is selects for individuals with traits of increased relative fitness (fitness= ability to produce viable offspring) Artificial selection is when people select for a desired trait.

None of the choices above are great...

first option: likely the best choice by process of elimination

second option: Artificial selection doesnt necessarily have to involve artificial insemination, though it can

3rd option: traits like color, markings, size and speed are not generally superficial... traits of color, markings and physical fitness (size/speed) often increase fitness in regards to sexual selection

The final option is simply false

Auxin is a class of plant growth hormones which play an essential role in coordination of many growth and behavioral processes in the plant life cycle.

Auxin is a plant hormone responsible for plant cell elongation, cell differentiation, cell division and healing in vascular cells, timing the growth of flowers, and general balanced growth of the entire plant.

Auxins affect plant growth in different ways. In shoots, the accumulation of auxins in the cell signals cell elongation. Whereas, the accumulation of auxins in plant roots signals the cells to not grow.

It would lead to the successful reintroduction of crested toads into the wild. The correct option is B

A Species Survival Plan (SSP) is a program designed to manage and conserve the genetic diversity of endangered or threatened species in captivity.

Therefore, Option B, "It would lead to the successful reintroduction of crested toads into the wild," is the most likely outcome of a Species Survival Plan for the crested toad population in Puerto Rico. While there may be challenges such as invasive species and habitat loss that could impact the success of the reintroduction efforts, the goal of the SSP is to help increase the population of the crested toad and prevent their extinction.

While researching the question of whether dinosaurs had feathers, Melanie decided to focus on

The paragraph implies that specific dinosaurs, belonging to the Theropoda group, could have potentially had feathers and revealed comparable traits with modern avians.

Consequently, Melanie's research would be best served delving further into the relationship between these Theropod dinosaurs and birds.

Alternative A neglects to establish any correlation between feather existence in dinosaurs, while alternative B has no significance as a determining factor for establishing dinosaur plumage. Although option D does possess some relevance, it fails to specifically address the crucial link connecting Theropod creatures with their avian counterparts.

B. The organism's shape and size.

Explanation:

A single fossil can provide information about the shape and size of the organism that it belonged to. Fossils can also provide information about the age of the rock layer in which they were found. However, it is usually difficult to determine other characteristics such as how many offspring the organism produced, its relationships to other organisms, or the life expectancy of similar organisms from a single fossil. These types of information often require the study of multiple fossils or the use of other scientific methods.

Maintaining a balance between the populations of kelp, otters, and urchins is important for the health and sustainability of the kelp forest ecosystem.

In a kelp forest ecosystem, kelp, otters, and urchins have a complex relationship. Kelp is the primary producer in the ecosystem and provides habitat and food for many organisms.

Otters are the primary predator of sea urchins, which are herbivores that feed on kelp. When otters are present in the ecosystem, they control the urchin population, allowing kelp to thrive. However, when otter populations decline, the urchin population can increase and overgraze the kelp, leading to a decrease in kelp abundance.

DNA polymerase can attach and add nucleotides to the free 3' end of a new RNA strand made of short segments of RNA nucleotides during DNA replication.

RNA primase first adds a short RNA primer to the 3' end of the template strand, which serves as a starting point for DNA polymerase to attach and add nucleotides in a 5' to 3' direction. DNA polymerase can only add nucleotides to the free 3' end of the RNA primer or an existing DNA strand. Once the RNA primer is replaced with DNA nucleotides, the lagging strand can be joined to the leading strand through DNA ligase.

This process of DNA replication is semi-conservative, meaning that each new double-stranded DNA molecule is composed of one parent strand and one new daughter strand. This mechanism of DNA replication ensures the accurate transfer of genetic information from parent to daughter cells during cell division.

A predator-prey dynamic tries to maintain balance in the populations of both species. The line in Figure below illustrates this. There is more food for predators as the number of prey rises. Thus, after a brief delay, the carnivore population also rises.

Explanation:

The relationship between the predator and prey graph lines can be shown graphically as a series of peaks and troughs that correspond to fluctuations in the population sizes of the predators and prey.

In a predator and prey graph, the predator and prey graph lines are typically related to each other in a cyclical pattern.

As the population of prey increases, the population of predators that feed on them will also increase, leading to a subsequent decrease in the population of prey due to predation. This decrease in prey population will then cause a decrease in predator population, as there is less food available for them.

This, in turn, will allow the prey population to recover and the cycle will repeat itself.

Answer:

B. How can farmers use less insecticides on their crops?

Explanation:

The scientists were most likely trying to answer question B, "How can farmers use less insecticides on their crops?" The Bt gene from Bacillus thuringiensis produces a protein that is toxic to certain insects, making the plants resistant to insect pests. By introducing this gene into crops, farmers can reduce the need for chemical insecticides, which can be harmful to the environment and human health. This approach is an example of genetic engineering for pest control, which has the potential to increase crop yields while reducing the use of harmful chemicals.

Answer: false

Answer:

Gymnosperms consist of four main phyla: the Coniferophyta, Cycadophyta, Gingkophyta and Gnetophyta.

Conifers are the dominant plant of the gymnosperms, having needle-like leaves and living in areas where the weather is cold and dry.

Cycads live in warm climates, have large, compound leaves, and are unusual in that they are pollinated by beetles rather than wind.

Gingko biloba is the only remaining species of the Gingkophyta and is usually resistant to pollution.

Gnetophytes are the gymnosperms believed to be most closely related to the angiosperms because of the presence of vessel elements within their stems.
