Answer:

As the cell grows, it faces some issues such as:

• Running out of the nutrients and requirement of growth factors.

• Running out of the space.

• Require appropriate gas exchange.

As compared to the smaller cells, larger cells have more issues in moving the required materials inside and excretory products outside. This is because the ratio of the surface is to volume is turning more and more unbalanced and takes much longer time for the cellular processes to take place.

olasank [31]

Answer:

D. Femoreal vein.

Explanation:

Close to the popliteal artery, the popliteal vein extends and transports blood from the knee (and also the muscles from the thigh and calf) once again up to the heart. This vein has its origin in the joint between both the anterior and posterior tibial veins, proximal to the knee.

Also, the popliteal vein starts its extension from the popliteal artery, which can be found behind the knee, and the drainage of the peroneal vein is performed by it prior to reaching the knee joint, where the popliteal vein becomes known as the femoral vein.

In the early 1700s, Linnaeus came up with a new system of classification of living things that eventually replaced the one that

antiseptic1488 [7]

Many biological systems classify the organism based on the cells, reproduction, simplicity and complexity. The discovery of the new species and arrangement based on the hierarchy led to the change.

<h3>What was the new classification system?</h3>

Aristotle gave the most primitive biological hierarchical classification system that was replaced by the system of the Linnaeus. He gave the classification based on the taxonomy groups.

With time many new organisms and species were discovered that did not fit in Aristotle's classification system. Hence, with time new systems were established to classify the organism based on many new parameters.

Therefore, option A. new system was established to classify the new organism discovered.

If you come across an unusual single-celled organism, what parts of the cell would you study in order to classify it into one of

<span>The correct answer is the nucleus and the cell wall. Cell walls and Nucleus are only found in specific cells. Prokaryotic cells are cells that do not have definite nucleus in their cells, while Animal Cells do not have cell walls, yet the Plant Cells have cell walls.</span>

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>
