What is the genotype of the male fly?

In order to set up your test cross, you must first realize that the male fly has one of two possible genotypes: Ee or EE. Because the male exhibits the dominant body color phenotype, you must cross it with a female with the homozygous recessive phenotype and genotype.

What organism can reproduce asexually?

The organisms that reproduce through asexual means are bacteria, archaea, many plants, fungi, and certain animals.

What was the one eukaryotic example of an animal that uses mitosis or asexual reproduction?

Lizards’ tails. These reptiles are also called anoles. In Florida, these lizards often lose part of their tail when a predator grabs at it. The tails can grow back; they do so through mitosis.

Which invertebrates reproduce asexually?

In this process, a single parent replicates body cells and divides into two individuals. Many invertebrates, including sea stars and sea anemones, reproduce in this manner. Common forms of asexual reproduction include: budding, gemmules, fragmentation, regeneration, binary fission, and parthenogenesis.

Which organism reproduces both sexually and asexually?

Plants. Daffodils are a plant that can reproduce both ways; asexually from their bulb and sexually through seed production. Strawberries are similar in that they can reproduce sexually through seed production, or asexually with runners that spread through the ground and create daughter plants from the parent.

How does the sea anemone respond to stimuli?

How does the sea anemone respond to stimuli? The sea anemone has a very simple nervous system; if you touch part of the sea anemone, the entire animal contracts. For example, if you touch a tentacle, the anemone quickly withdraws all tentacles into its fleshy polyp.

Are all jellyfish diploblastic?

anemones, jellyfish, and corals—has a diploblastic level of organization (i.e., its members have two layers of cells).

Are cnidarians diploblastic?

Cnidarians are generally regarded as diploblastic animals, possessing endoderm and ectoderm, but lacking mesoderm.

Are cnidarians diploblastic?

Cnidarians are generally regarded as diploblastic animals, possessing endoderm and ectoderm, but lacking mesoderm.

Are sea anemones dioecious?

Reproduction in three species of sea anemones from Key West, Florida, was studied from October 1977 until July 1978. pattern, based on the scheme of Chia, modified by the author. Phymanthus crucifer is also dioecious and exhibits a sex ratio not significantly different from 1:l; however, this species is viviparous.

Can you feel polyps with your finger?

A doctor may be able to feel polyps by inserting a gloved finger into the rectum, but usually polyps are discovered when colonoscopy is done to examine the entire large intestine.

Can you poop out a polyp?

Usually, they are discovered and resected during colonoscopy. The spontaneous expulsion per rectum of a colorectal polyp is exceedingly rare. Here, we report a rare and unusual case that we believe is the first of spontaneous expulsion of an adenomatous polyp during defecation.

Do anemones use alkalinity?

Alkalinity is more important to anemones than calcium, but calcium and alkalinity need to be balanced in any marine system growing inverts. It’s very important to grasp this basic understanding before attempting anything.

Do bubble tip anemones split?

clarky2120 Bubble Tip Anemone The anemone splits when it feels it is in danger. ie: bad water conditions or more likely not enough food. It splits when signs are bad as a defense because twos smaller ones have a better chance of surviving than one bigger one.

Do fish like being pets?

“It is a basic characteristic of animal behavior that animals will approach desirable things and retreat from undesirable ones,” he said, adding that the fish “appears to like the touch because s/he swims back to the hand repeatedly.”

Do phylum cnidaria have nervous system?

Cnidarians have simple nervous systems and it was probably within this group or a closely-related ancestor that nervous systems first evolved. … We propose that these multifunctional neurons resemble the ancestors of the more specialized neurons that we find in higher animals today.

Do sea anemones have a circulatory system?

Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it. They obtain nutrients and oxygen directly from the water that they live in.

Do sea anemones have nervous systems?

The phylum Cnidaria includes sea anemones, hydra, and jellyfish, all of which have nervous systems without glial cells.

How do anemones hunt their prey?

Anemones have rings of tentacles surrounding their central mouth. Tentacles have specialised stinging cells called nematocysts. They use these to immobilise their prey so that the tentacles are then able to move the food into the mouth. The extending tentacles can also be used to catch passing food as it drifts past.

How do anemones specifically hunt their prey?

Sea anemones are typically predators, ensnaring prey of suitable size that comes within reach of their tentacles and immobilizing it with the aid of their nematocysts. The prey is then transported to the mouth and thrust into the pharynx.

How do cnidarian polyps move?

Medusae swim by jet propulsion (see below Tissues and muscles). However, most do so weakly and are carried passively by currents over long distances. Polyps are generally sedentary.

How do cnidarians respond to stimuli?

To respond to stimuli, cnidarians use a rudimentary muscular system consisting of muscle cells lying in bands up and down the body wall and in a circle around the mouth cavity (Fig. 3.27). The body shortens when the vertical bands contract. If muscles on only one side contract, the body bends in that direction.
