____________________________ is the process in which humans chose the desired traits of an organism.
a
Artificial selection
b
Natural selection
c
Biology
d
Variation
Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

What are the characteristics of saturated fatty acids? Check all that apply. Each carbon atom in the carboxylic acid chain is bonded to at least two hydrogen atoms. At least one double bond links carbon atoms in the carboxylic acid chain. The lipid is a straight chain. The lipid is a liquid at room temperature. The lipid is a solid at room temperature.
Each carbon atom in the carboxylic acid chain is bonded to at least two hydrogen atoms and The lipid is a solid at room temperature are the characteristics of saturated fatty acids.
Where are saturated fatty acids found?
Although plant foods like coconut, coconut oil, palm oil, and palm kernel oil are high in saturated fats, saturated fat is mostly found in animal meals. However, replacing saturated fat with refined carbs will probably negate the benefits of cutting back on saturated fat.
No carbon-to-carbon double bonds can be found in saturated fatty acids, while one can be found in monounsaturated fatty acids and two or more can be found in polyunsaturated fatty acids. Since there are enough hydrogen atoms in the saturated fatty acid molecule, every carbon atom is single-bonded. A carbon atom at the end of a chain of saturated fatty acids is doubly linked to an oxygen atom and singly bonded to a hydroxyl group.

what is the effect of Dideoxycytidine on the replication of viral DNA.
Answer:
Several 2',3'-dideoxy-3'-thiapyrimidine nucleosides were studied for their ability to inhibit hepatitis B virus (HBV) DNA replication in a HBV-transfected cell line (2.2.15). 2',3'-Dideoxy-3'-thiacytidine (SddC) and 5-fluoro-2',3'-dideoxy-3'-thiacytidine(5-FSddC) were found to be the most potent anti-HBV compounds of those examined. Both compounds resulted in nearly complete cessation of viral DNA replication at 0.5 microM, as monitored by the absence of both intracellular episomal and secreted viral DNAs. The HBV-specific RNAs were not reduced at concentrations that completely blocked HBV DNA replication, suggesting that the inhibitory target is HBV DNA synthesis. The antiviral action of SddC and 5-FSddC was reversible. The concentration of SddC and 5-FSddC required to inhibit 50% of 4-day cell growth in culture was 37 microM and more than 200 microM, respectively. Unlike 2',3'-dideoxycytidine, these two compounds do not affect mitochondrial DNA synthesis in cells at concentrations lower than that required to inhibit cell growth. In view of the potent and selective antiviral activity, both SddC and 5-FSddC should be further evaluated for the treatment of human HBV infection.
Explanation:
Apply what you know about lipids to explain why the cuticle helps prevent water loss in plants. Compare it to what humans do.
Answer:
Explanation:
Waxy cuticle is a white powdery substance that is insoluble, it is found usually on the surface of stem or leave and it prevent excessive loss of water through transpiration.
It is an adaptive mechanism used in dry areas or desert to help plants retain water that is needed for their growth by reducing amount of water loss through transpiration.
Cactus is an example of plant with cuticle that thrive well in dry areas

A 38-year-old mother of three presents to her primary care office with complaints of fatigue. She feels that her energy level has been low for the past 3 months. She was previously healthy and taking no medications. She does report that she has gained about 10 lb and has severe constipation, for which she has been taking a number of laxatives. A TSH is elevated at 25 mU/L. Free T4 is low. She is wondering why she has hypothyroidism. Which of the following tests is most likely to diagnose the etiology?
A. Antithyroid peroxidase antibody
B. Antithyroglobulin antibody
C. Radioiodine uptake scan
D. Serum thyroglobulin level
E. Thyroid ultrasound
Answer:
A. Antithyroid peroxidase antibody
Explanation:
The most common cause of hypothyroidism is autoimmune thyroiditis, also known as chronic lymphocytic thyroiditis or Hashimoto's disease. This condition (autoimmune thyroiditis) is caused by damage of the thyroid gland, which occurs when antibodies of the immune system attack this gland. The thyroid peroxidase test is an enzyme immunoassay widely used to measure the level of autoantibodies against thyroid peroxidase. Patients with chronic thyroiditis often display a positive thyroid peroxidase test. On the other hand, thyroid ultrasound is useful for the initial evaluation of painless thyroiditis in order to distinguish nodules or multinodular goiter. Antithyroid peroxidase antibodies are commonly observed in individuals suffering autoimmune thyroiditis, whereas antithyroglobulin antibodies are observed in different thyroid disorders and autoimmune diseases. Finally, a radioiodine uptake scan measures the amount of radioactive iodine accumulated in the thyroid gland, which is useful only for diagnosing early‐stage of Hashimoto's thyroiditis.

Through photosynthesis, plants
A convert starch to sugar
B convert radiant energy
to chemical energy
C turn water into fructose
D All of the above
Answer: I think its all of the above
Explanation:
photosynthesis is the process through which light energy is converted into either chemical energy or sugar. ... Some of the sugar is also stored for use later, by being converted into starch.
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water.
At the end of photosynthesis, a plant ends up with glucose (C6H12O6), oxygen (O2) and water (H2O). ... They can even put the glucose into other sugars — such as fructose — to make a plant's fruit sweet. All of these molecules are carbohydrates — chemicals containing carbon, oxygen and hydrogen.

What Are Alleles? Where Do alleles come from?
Answer:
An allele is one of two more versions of a gene. An individual inherits two alleles for each gene,one for each parent.
Explanation:
Part-1
An allele is a variant form of a gene. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
For example: an allele is the gene that determines hair color.

Answer:
Drogas.
Explanation:
Las drogas son sustancias que tienen un efecto modificatorio sobre el estado normal de la psique. Por tanto, estas sustancias influyen en el comportamiento o la experiencia del usuario, pudiendo tener un efecto alucinógeno, pero también sedantes o una mixtura entre ambos.
El término se usa generalmente para indicar sustancias que tienen un efecto muy fuerte (por ejemplo, heroína, cannabis, mescalina, alcohol). Aunque los estimulantes cotidianos como el café y el chocolate también pueden tener un efecto en la psique, generalmente no se clasifican como sustancias psicoactivas debido a su efecto relativamente leve.
Los medicamentos que tienen un efecto sobre la psique se denominan psicofármacos. No obstante, los medicamentos que no se clasifican principalmente como psicofármacos, como los antihistamínicos, los agentes anti-mareo y los betabloqueantes, pueden también tener un efecto psicotrópico.

Please helppp
Answer:
“Hard limits” to population growth are things like food, water, energy, technology, living space, other basic needs and economic factors which limit people’s ability to access these things.
“Soft limits” to population growth are things like education, birth control, the desire for a better life individually and a better global future for humanity, religious celibacy or chastity or abstinence, female empowerment and economic participation, the suffering already caused by overpopulation and the desire to avoid further suffering, malnutrition or non-lethal starvation which reduces sexual libido, pollution and other man made causes of involuntary sterility or low sperm count or low fertility, desire to save the environment, aversion to pain and suffering when understood that population growth causes both.
Countries with better quality of life and access to food and basic needs often have lower birth rates and lower population growth. This shows that soft limits can actually be more effective than hard limits to stop population growth. You have plenty of countries in Africa running into hard limits and having some of the highest fertility and population growth rates at the same time. They also suffer massive problems like war, poverty, disease and low standard of living. This goes to show that running into the hard limits will pretty much let things get as bad as they can get before it stops population growth. The hard limits won’t stop all the suffering caused by overpopulation but will make enough people suffer TO DEATH that the population doesn’t grow. People fear pain, thus the soft limits are more effective when they understand that population growth was responsible for pain or suffering and avoid it.
