I think that evolution by way of natural selection is most likely a statement of fact that is generally accepted to be true and universal because it has always been observed to be true. It is a theory because it is based on evidence and repeated testings.


Answer: C) a statement of fact that is generally accepted to be true and universal because it has always been observed to be true.

Dichotomous keys ask A.open-ended questions about animal behavior. B.open-ended questions about easily observable characteristics. C.yes-or-no questions about animal behavior. D.yes-or-no questions about easily observable characteristics.

The right option is; D.yes-or-no questions about easily observable characteristics.

A dichotomous key is a tool designed by scientists to help its users to identify a particular type of object and organisms based on physical characteristics. A dichotomous key is divided into two sections and it usually contains specific questions with two choices (yes or no) in each step. When a question is answered, the key guides the user to the next question to ask until the user is able to correctly identify the name of the unknown organism.

In pea plants, yellow (Y) seed color is a dominant trait, and green seed color (y) is a recessive trait. Which resulting plant with yellow seeds could produce a plant with green seeds in the next generation? A. YY B. Yy C. yy D. Yg

Answer: The correct answer is-

B. Yy

As per the information in the question,  yellow (depicted by Y allele) seed color is a dominant trait whereas green seed color is a recessive trait ( depicted by y allele).

A dominant trait always masks the expression of a recessive trait.

Presence of single dominant allele ( such as in Yy, which shows heterozygous dominant genotype) in the genotype can produce a dominant trait whereas recessive trait is only expressed when its genotype is homozygous recessive (such as yy that is both alleles should be recessive allele) .

A plant with genotype Yy will form two gametes that is Y and y.

When such plants are allowed to interbreed, there is a probability of 25% of producing green seeds in the next generation.

Which statement explains why sugar dissolves easily in water, but sand does not? Sugar has a greater buoyant force than sand. Sugar has a greater conductivity than sand. Sugar has a greater hardness than sand. Sugar has a greater solubility than sand.

  • Sugar dissolves easily in water, but sand does not because sugar has greater solubility than sand.
  • A solution is made by mixing a substance (solute) in a medium (solvent). The chemical property of the solute that describes how easily the solute will dissolve in a given solvent is known as its solubility.
  • The greater the solubility of a solute the more easily it dissolves in a solvent.
  • The solubility of different solutes varies from each other and, also varies from one solvent to another.
  • If we compare sugar and sand then sugar has more solubility in water as compared to sand and, is able to dissolve more quickly and easily.

Describe several types of agal colonies

Although the term algae originally referred to aquatic plants, it is now broadly used to include a number of different groups of unrelated organisms. There are seven divisions of organisms that make up the algae. They are grouped according to the types of pigments they use for photosynthesis, the makeup of their cell walls, the types of carbohydrate compounds they store for energy, and the types of flagella (whiplike structures) they use for movement. The colors of the algae types are due to their particular mixtures of photosynthetic pigments, which typically include a combination of one or more of the green-colored chlorophylls as their primary pigments.

A microbiologist is in the process of classifying a newly discovered organism. Its characteristics include: · eukaryotic · multicellular · reproduces by spores · motile in some stage of its life cycle · decomposer Which type of organism is it most likely to be? club fungus fungus-like protist plant-like protist sac fungus

Based on the characteristics of the new organism discovered by the biologist, it can be concluded that this organism is most likely a fungus-like protist. The organism is a multi-cellular eukaryote who reproduced by the spores and is motile in few stages of the life cycle. Besides all this it is a decomposer. This all characteristics fit the description of a fungus like protist. They are most commonly found on the dead wood, but they also produce spores like the fungi.

Hence, the correct answer is 'fungus-like protist'.

Explanation:

Waterfront neighbourhoods encounter two low tides and two high tides each lunar day, or 24 hours and 50 minutes. The two tidal bumps are created by inertia and gravity which revolve around the Earth as the moons state shifts. These bumps indicate high tides while the smooth sides represent low tides.

What is the difference between early telophase and late telophase?Only answer if YOU KNOW!

During telophase, nuclear membranes reform around each set of genetic information. Having performed their function, the spindle fibers that pulled the chromosomes to the poles of the cell disappear. The chromosome doesn’t need to be in a compact form anymore, so it uncoils, allowing better access for the transcription processes that read the genetic information in order to create proteins and enzymes. At the end of telophase, there are two separate nuclei, each with a copy of the original cell’s DNA.

Late telophase is when the cell completes the division and replication of its genetic information. At this point, the nuclear envelope has fully reformed and the DNA has unfurled, so there are two nuclei in the cell. The chromosomes only have one centriole, where the sister chromatids were attached, so the chromosome forms a second centriole next to the first in anticipation of the next division. At the same time as late telophase, the cytoplasm and cell membranes separate into two cells, a process known as cytokinesis.

Most streams result from what

Answer:

A stream refers to a water body with the surface water flowing within the banks and bed of a channel. The stream generally results due to the majority of the water coming from snow and rain. The majority of this water gets entered into the atmosphere again by the process of evaporation from water bodies and soil, or by plant’s evapotranspiration. Some of the water continues to sink into the Earth by infiltration and turns into groundwater, the majority of which ultimately goes into the streams.

Many people try to eliminate fat from their diets. Which is one reason it is necessary for humans to eat fat? A.The internal organs are cushioned by fat. B.Eating fat is the fastest way to get energy. C.Fat stores less energy than polysaccharides. D.Saturated fats clear out the blood vessels.

Answer;

A.The internal organs are cushioned by fat.

Explanation;

-Most of the nutrients in food fall into three major groups: proteins, fats, and carbohydrates. The body uses fat as a fuel source, and fat is the major storage form of energy in the body.By supplying energy, fats save proteins from being used for energy and allow them to perform their more important role of building and repairing tissues.

Fat also has many other important functions in the body, and a moderate amount is needed in the diet for good health.They also cushion internal organs, provide insulation against temperature and also facilitate absorption of fat soluble vitamins.

Use the Amino Acid Chart on this page to answer the questions below. Transcription – Translation (transcribe to mRNA, then decode for amino acids) DNA: TAC GCG AAT ATC a A) START – Lysine – Leucine – Glycine b B) START – Arginine – Leucine – STOP c C) START – Serine – Cysteine – Phenylalanine – STOP d D) Methionine – Lysine – Leucine – STOP

The right answer is B) START – Arginine – Leucine – STOP .

RNA transcribed from this DNA consists of:  AUC - CGC - UUA - UAG.

AUC is the start codon.

CGC codes for Arginine.

UAA codes for Leucine.

UAG is a one of the stop codons.

The genetic code is the set of rules for translating the information contained in the genome of living cells in order to synthesize proteins. In a broad sense, it establishes the correspondence between the genotype and the phenotype of an organism. This code is based in particular on the correspondence between, on the one hand, the nucleotide triplets, called codons, on the messenger RNA and, on the other hand, the proteinigenic amino acids incorporated in the proteins synthesized during the translation phase of messenger RNA by ribosomes.
