Organisms that obtain and ingest organic molecules for their nutrition are classified as.
Answer:
Also refered to as consumers, heterotrophs are organisms that obtain their energy (nutrition) from organic compounds/materials. In other words, they are organisms that are unable to produce their own food (unlike autotrophs) and therefore have to consume/ingest organic compounds as a source of energy.

Bases rarely react with metals.
Do bases react with most metals?
Some metal reacts with a base to form salts and hydrogen gas. Most metals do not react with bases but zinc metal does because it is amphoteric. That is, it reacts with acids as well as bases. When sodium hydroxide solution is heated with zinc, then sodium zincate and hydrogen gas are formed.
Which metals do not react with bases?Metals form salts by transforming themselves into cations and combining with the anions present in the acids. Hence, not all metals react with bases, only amphoteric metals like zinc and aluminium react with bases.

What is the first procoagulant that the extrinsic and intrinsic pathways have in common?.
Answer:
Prothrombin is activated to thrombin.Factor X is the first procoagulant that the extrinsic and intrinsic pathways of the blood clotting system have in common. Thus, option D is correct.
What is the blood clotting pathway?Blood clotting is the process to stop the flow of blood from the injury. There are two pathways the extrinsic and the intrinsic that have Factor X as the common procoagulant.
Factor X or the Stuart factor is synthesized in the liver and interacts with the other procoagulant in the blood clotting pathway to form a clot and stop bleeding.
Therefore, Factor X is the common procoagulant in the intrinsic and extrinsic pathways of blood clotting.

Answer: There is a 100% chance of a heterozygous offspring, or an offspring with the allele Pp
Explanation: This percentage is calculated by looking at the total number of Pp divided over the number of possiblities. In this case there are 4 Pp, divided by 4 possible variations from the two parent alleles, making it a 4/4 or 1/1 orrr 100% chance of getting a Pp, or heterozygous offspring.

In 1978, scientists studied how the fitness of marine sticklebacks would be affected if they were introduced into a freshwater environment. They collected 90 male and 90 female sticklebacks from a marine population and 10 male and 10 female sticklebacks from a freshwater population. The 200 sticklebacks were introduced into a freshwater environment that had no stickleback fish previously.
Recently a scientist decided to repeat this study, but relocated a population of sticklebacks from a freshwater environment into a marine environment. Which of the following best predicts how the frequency of the allele would change over time if a population of sticklebacks from a freshwater environment was placed into a marine environment?
The frequency of alleles in the population started low and continued to increase over time.
What is frequency of alleles?The frequency of alleles refers to the ratio of the number of times an allele occurs to the copies of all the alleles at that particular genetic locus in the given population.
We can see that the sticklebacks had a greater number of those introduced from marine to fresh water hence of the 200 sticklebacks, the frequency of alleles in the population started low and continued to increase over time.

Describe the components and structure of a DNA nucleotide
Answer:
Nucleotide
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.

O bacteria
O flagellates
Answer:
Explanation:
1. ecosystem
2. arthropods
3. Microscopic models move at a much faster rate than large-scale systems.
4. algae
100%
If you were analyzing a microscopic model of a freshwater ecosystem, one autotroph that you might encounter is an alga. Thus, the correct option for this question is B.
What is an Ecosystem?An ecosystem may be defined as a type of place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
According to the context of this question, algae are generally found in the freshwater ecosystem as well. They significantly utilize the nutrients from other water bodies and grow appropriately. While organisms like ciliates, bacteria, and flagellates are found in polluted or salty/marine water.
Therefore, if you were analyzing a microscopic model of a freshwater ecosystem, one autotroph that you might encounter is an alga. Thus, the correct option for this question is B.

Why are start and end amino acids encoded by only one codon?
Answer:
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

In other words, researchers study how the same genotype can lead to very different phenotypes Genotype. Phenotype. The hereditary information of the organism in the form of gene in the DNA and remains the same throughout the life. The characters of an organism which are visible are known as phenotypes.
Explanation:
Hope this helps! :)
The study of how the same genotype may lead to different phenotypes is known as epigenetics.
What is epigenetics?Epigenetics is the study of how environmental factors and behaviour can alter how your genes function.
While epigenetic alterations are reversible and do not alter your DNA sequence like genetic changes do, they can alter how your body interprets a DNA sequence.
In biology, the study of persistent phenotypic changes that do not entail changes in the DNA sequence is known as epigenetics.
The word "epigenetics" comes from the Greek prefix epi, which denotes characteristics that are "on top of" or "in addition to" the conventional genetic basis for heredity.
Epigenetic patterns may be affected by a number of lifestyle factors, including food, obesity, physical activity, alcohol consumption, smoking, exposure to environmental toxins, stress, and working night shifts.
Thus, the answer is epigenetics.
