Answer:

The options of this question are wrong, you can find the correct options by navigating on the web. The options of this question are as follow:

1) The sister species will continue to diverge from each other.

2) None of the sister species will interbreed with each other.

3) The Atlantic and Pacific shrimp will continue to live in their respective oceans and not enter the new canal.

4) Shallow-water species from the two oceans that are sister species would be more likely to interbreed with each other than would be deep-water species.

Answer:

4) Shallow-water species from the two oceans that are sister species would be more likely to interbreed with each other than would be deep-water species

Explanation:

In evolutionary biology, sister species are defined as descendant species formed when one species splits during the course of evolution. Moreover, adaptation refers to the evolutionary process of adjustment of organisms to the environment, which is usually due to natural selection. During the course of evolution, organisms under different environments must change to adapt to their environments. In this case, it is expected that sister species that live in similar environmental conditions (i.e., shallow-water species) exhibit fewer phenotypic differences, being therefore more likely to interbreed with each other.

The group of macromolecules that can be affected by Keto's eating choices, and is used for long-term storage, in addition to being insoluble in water, is lipid.

The ketogenic diet consists of significantly reducing the amount of carbohydrates ingested daily and adding more fat to the diet.

After about three weeks of reducing carbohydrates from the diet, the body enters a metabolic state called ketosis, turning stored fat as the body's energy source.

Therefore, the ketogenic diet can bring benefits to the individual, such as accelerated weight loss and prolonged satiety, but it can also be a difficult diet to follow for long periods, as it is more restrictive.

The ideal, then, is always to seek specialized help when you want to achieve some aesthetic or health goal related to weight loss, so that the professional can develop a diet focused on the needs and individualities of each one.

A geologic feature with at least three layers that demonstrates the principle of lateral continuity is called a Grand Canyon.

According to the lateral continuity concept, sedimentary rock strata were formerly continuous over wide areas. As a result, any layer discontinuities must be the result of erosion or other geologic processes.

The layers in this sketch are continuous laterally, which means they extend in all directions while holding onto their thickness and makeup. We can presume that the layers go farther in all directions even though we can only see a small section of them in this sketch. This is significant because it enables geologists to link the age and make-up of distinct rock layers.

B. The bacteria reproduced asexually. This evidence suggests that the bacteria reproduce asexually.

The majority of bacteria use binary fission to spread. Conceptually, this is a straightforward procedure; a cell only needs to double in size before splitting in half.

Binary fission in bacteria resembles human and other eukaryotic organisms' mitosis in certain aspects. In both circumstances, chromosomes are copied and segregated, and the cell splits its cytoplasm to generate two new cells.

Asexual reproduction can occur through binary fission, budding, vegetative propagation, spore formation (sporogenesis), fragmentation, parthenogenesis, and apomixis, among other processes. Bacteria, archaea, many plants, fungi, and some animals are examples of organisms that reproduce asexually.

The type of reproduction that Pisum sativum undergoes is sexual reproduction because it involves the fusion of male and female gametes.

Sexual reproduction is a type of reproduction that involves the formation of a new organism by combining the genetic material of two organisms.

The genetic material of each parent organism is located in the gametes (sperm and egg) produced during the process of meiosis.

According to this question, Gregor Mendel is said to be famous for his experiments on Pisum sativum (pea plant) which is capable of self-fertilizing by combining its own male and female gametes.

the trophic pyramid is the reason

what the trophic pyramid is:  Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers

- predators get little energy from the prey they eat so they must consume multiple prey

It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

The food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.

Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.

The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.

The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.

Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
