A cross between heterozygotes for a single trait will lead to a genotypic ratio of 1:2:1. How many phenotypes will be observed if incomplete dominance is occurring

Answers

There will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

What is incomplete dominance?

The so-called incomplete dominance is the one in which the alleles are expressed in heterozygosity, however, they produce an intermediate phenotype, since none is totally dominant. In the case of complete dominance, the phenotype is equal between zygotes and heterozygotes.

With these information, we can conclude that there will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

Answers

The primary reservoir for calcium that is released during excitation-contraction coupling in a skeletal muscle fiber is sarcoplasmic reticulum.

What is the function of sarcoplasmic reticulum?

The sarcoplasmic reticulum is responsible for storeing calcium ions which it releases when a muscle cell is stimulated.

So we can conclude that the primary reservoir for calcium that is released during excitation-contraction coupling in a skeletal muscle fiber is sarcoplasmic reticulum.

why human cell is considered as eukaryotic cell where as bacterial cell as prokaryotic cell​

Answers

Answer:

Humans are eukaryotes. Like all other eukaryotes, human cells have a membrane-bound organelles and a definite nucleus.

Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

Explanation:

Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.

Fossils are a term we use to refer to the remains of prehistoric organisms. This means organisms that lived a very long time ago. Fossils are notoriously rare and difficult to find and can come in varying stages of preservation. These fossils provide valuable information as to the species of organisms that existed many centuries ago.

Explain why increasing the trophic level always results in a decrease in organisms
(biomass) and energy.

Answers

Answer:

With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.

Answer:

Increasing the trophic level always results in a decrease in organisms (biomass) and energy because When energy decreases, it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Only a fraction of the energy available at one trophic level is transferred to the next trophic level. Typically the numbers and biomass of organisms decrease as one ascends the food chain.

Red pandas and raccoons have similar skull patterns that are not shared by the giant panda, spectacled bear, and sloth bear is correct regarding phylogenetic tree.

What is phylogenetic tree?

A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.

Phylogenies are helpful for classifying organisms, organizing knowledge of biological diversity, and shedding light on evolutionary processes.

Furthermore, one needs to comprehend phylogenies in order to fully appreciate the overwhelming evidence in favor of evolution since these trees demonstrate descent from a common ancestor and since common ancestry constitutes most of the strongest evidence for evolution.

Therefore, Red pandas and raccoons have similar skull patterns that are not shared by the giant panda, spectacled bear, and sloth bear is correct regarding phylogenetic tree.
