The answer is c. sunlight. when plants are making their food, they incorporate carbon dioxide, air and water from the soil. This process is called Photosynthesis The plant uses the sunlight's energy to create food. They are often trapped by the green pigment in the plant called chlorophyll.

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.

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'.

Why might introduction of exotic species disrupt an ecosystem? A. They're struggling to survive and can be disruptive. B. They die quickly and overfeed scavengers. C. There are very few of the organisms present. D. They can outcompete native species.

Answer: D. They can outcompete native species.

Exotic species are the species which are not native to the region to which they are introduced. They can be referred as alien, non indegenous species. These species are introduced either due to human intervention in order to use these species for their own benefit or these species migrate from their native land in search of food and other resources. These species may act as an invasive species, which means they compete with the native population for resources. Therefore, they will disturb the natural biodiversity of the ecosystem.

Hence, exotic species when introduced in an ecosystem they can outcompete native species.

Humans cannot digest food without the aid of small single-celled organisms that live in our digestive tract. These small organisms help humans digest food by breaking down complex food molecules. Which common name is associated with these single-celled organisms that help humans digest food? A) algae B) bacteria C) protozoa D) virus

Bacteria are single-celled organisms that help humans digest food.

Explanation:

The symbiotic association of bacteria and human is of importance in the process of digestion. These bacterias are found in our gut, large intestine and sometimes in small intestine also. These bacteria break down big molecules into useful forms. Bacteria are also responsible for producing vitamin k2 and vitamin B in large intestine. They also help in mobilising of xenobiotics, bile and sterols.

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.

QUESTION POSTED AT 23/02/2020 - 11:27 PM

18. In a species of wild animal, claw size is determined by a combination of two alleles. Allele Q codes for large claws, while allele q codes for small claws. Individuals with a heterozygous genotype possess claws of medium size. Members of the species depend on their claws to be able to burrow in the ground and find food. But in an area where the ground has always been soft, gradual climate change has caused the dirt to become hard and compact. Which statement best predicts the change that will occur in the affected populations? A. Allele q will decrease in frequency. B. Allele q will become dominant to allele Q. C. Allele Q will become dominant to allele q. D. Allele Q will decrease in frequency.

Answer: The correct answer is- A) Allele q will decrease in frequency.

According to the information in the question, allele Q codes for large claws and allele q codes for small claws in a species of wild animal.

This indicates that larger claws will enable the wild animals to burrow more in the ground and find their food. As the change in the climatic conditions caused the dirt on the ground to become hard and compact.

This will result in change in the frequency of allele of the population as allele Q will increase because larger claws will provide more advantage (in context of burrowing) to the animals for getting their food, whereas frequency of q allele will decrease ( as smaller size of claws will not be that beneficial to them in hard and compact ground).

Thus, option A) is the right answer.
