How many chambers does a frog heart have and why is this advancement necessary for a land animal?

1 answer:

5 0

A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.

This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.

In the Calvin cycle more atp than nadph is used how is this difference made up

Veseljchak [2.6K]

Answer:

Explanation:

The detailed description of photosynthesis is that chlorophyll a becomes oxidized chlorophyll a after being irradiated, and the water in the thylakoid is oxidized by oxidized chlorophyll a to form oxygen and hydrogen ions, and hydrogen ions pass through the class. The ATP synthase on the capsule membrane passes through the membrane into the chloroplast matrix, where it provides a certain chemical potential (ie, an energy produced from a high concentration to a low concentration), and then ADP and Pi on the membrane. Will get energy to form ATP; and NADPH+ is the front chlorophyll a is oxidized by light to release high-energy electrons e, e will be transferred to NADP+ (oxidized coenzyme II), the photolysis of the front water does not produce hydrogen ions? This led to the combination of NADP and H+, which became NADPH.

Next, their use, in front of the photoreaction, in the dark reaction, CO2 will react with the five-carbon compound in the chloroplast matrix, fixed to the formation of a three-carbon compound (one C in CO2, five C in five-carbon compound, Two three-carbon compounds are formed, and then ATP and NADPH supply hydrogen, respectively, and then return to ADP+Pi and NADP+, and the reduced three-carbon compound becomes organic (mostly sugar) and becomes The five-carbon compound will react with CO2 again, which is the Calvin cycle.

<em>Genetic mutation is an important factor that contributes to the pathogenesis and development of Alzheimer’s disease (AD). The genetic factors studied include the dominant mutations of genes encoding amyloid-β precursor protein (APP), presenilin 1 (PSEN1), and presenilin 2 (PSEN2). Additionally, more and more genes have been found to be potentially associated with AD, such as apolipoprotein E (APOE), glycogen synthase kinase 3 beta (GSK3B), dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A), and Tau. Although many studies on the treatment of AD have not been successful, gene therapy is still considered as a potential way against AD, and some gene-therapy-based therapeutics have entered the clinical trial stage. Existing strategies for gene therapy against AD include gene inactivation, genetic modification, and immunoregulation, etc.</em>

If a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, what would happen to

BabaBlast [244]

The paramecium would not be able to get rid of excess water so the cell would burst.

FUNCTION OF THE CONTRACTILE VACUOLE:

The contractile vacuole is an organelle present in protist organisms like paramecium, amoeba etc.

The contractile vacuole functions to regulate water balance in the cells of organisms that they are found. Contractile vacuole performs this function by storing excess water and expelling the out of the cell.

Hence, if a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, the paramecium would not be able to get rid of excess water so the cell would burst.

if a single-celled organism is unable to undergo cell division, which of its life functions is affected?

castortr0y [4]

Answer:

The correct answer would be reproduction.

Single-celled organisms usually reproduce asexually with the help of cell division.

Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.

Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.

Unicellular organism usually divide by fission either binary or multiple.

In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.

In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.
