According to the cell theory, the cell is the basic unit of life. All living organisms are composed of one or more cells. Based on the organization of their cellular structures, all living cells can be divided into two groups: prokaryotic and eukaryotic (also spelled procaryotic and eucaryotic).

3. Which of the following reflect reasons for America's interest in the Panama Canal?

Rom4ik [11]

"To facilitate the faster movement of naval ships from the Atlantic to the Pacific" reflect one of the reasons for America's interest in the Panama Canal.

Answer: Option E

Explanation:

Panama Canal is an artificial or man-made waterway of 82 km located in transcontinental country in Central America and South America named as "Panama". France was the very first nation to start work on the canal in 1881 but after some engineering issues they eliminated themselves from the project.

In 1901 the United States leaded the project which finally resulted into inaugural ceremony of the panama canal on 15th August, 1914.The bypass, one of the largest and most complex engineering projects ever undertaken, significantly reduced the time for ships to pass between the Atlantic and Pacific oceans. Therefore it allowed them to avoid the long, risky Cape Horn path around the southernmost tip of South America via the Drake Passage or Magellan Strait.

Jan's sister and mother have both had breast cancer. She is wondering if she should undergo genetic testing to check for a mutat

Lynna [10]

A) Yes, Jan should undergo genetic sequencing.
BRCA1/BRCA2 are the causes of 20-25% of all hereditary breast cancers, so if Jan's mother and sister both have breast cancer, then the odds are that she has BRCA1 as well.

B)
Pros: If she does have an abnormal BRCA1 gene, she can take steps to lower her risk of breast cancer.

Cons: The tests can incite discrimination towards her in the workplace, and having it known she has a risk for breast cancer can severely increase the cost of insurance.

C) Genetic sequencing could affect the frequency of genetic diseases because the test could point out --- I can't finish because I have to go. I'm so sorry, reask the url of this question and ask someone to finish. Have a nice day!

Which of the following plants do NOT have swimming sperm?

Furkat [3]

Answer:

None of these.

Explanation: The plants like cycads and ginkgos have swimming sperms. they need water to complete their life cycle.

There are many adaptations seen in the plants like liveworts, ferns and mosses in which they require water to complete its life cycle. This adaptation is not only restricted upto cyptograms. This can also be seen in the plants like ginkgos and cycads. Their sperms are very strange.

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.

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.
