Peppermint shrimp are also hermaphrodites.

One of the reasons for any organism to be a simultaneous hermaphrodite is that they may live in habitats/areas where it's difficult to find a mate/the gender ratio is skewed toward one gender/the organisms are sessile and cannot move to find a mate of the opposite gender. The ability of a species to develop hermaphroditism allows any two individuals that come into contact to mate.

For sequential hermaphroditism, there's usually a benefit to being one gender or the other (larger size for protecting the smaller members of the opposite gender, able to produce more eggs).

Unfortunately, I don't think there's any one condition/niche that works for all hermaphroditic species.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation

Soloha48 [4]

Answer:

The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.

Explanation:

In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.

Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?1 breaki

max2010maxim [7]

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.

malfutka [58]

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. Preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine and this is Inactivated type of Vaccine.

<h3>What exactly are pathogens?</h3>

Pathogens include viruses, bacteria, fungi, and parasites that can enter the body and harm the immune system. Among many additional viruses that can lead to serious illnesses are anthrax, HIV, the Epstein-Barr virus, and the Zika virus.

<h3>What is vaccination?</h3>

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular infections.

<h3>Inactivated vaccine:</h3>

In inactivated immunizations, the disease-causing microorganism is eliminated.

Inactivated vaccines typically don't provide as strong of immunity (protection) as live vaccines. Therefore, it can take several doses (booster injections) throughout time to keep up your resistance to diseases.

Using inactivated vaccinations, you can guard against

Flu
Hepatitis A
Polio
Rabies
