Which pair of organism represents a predator prey relationship
Answer:
Explanation:
hawk and mouse
Answer:
Coyote and Rabbit. Coyote will eat the rabbit. (See more down below.)
Explanation:
Bear (Pred) will snatch up a fish (prey) out of a river. Bear and Fish.
Lion (Pred) eats a Zebra (prey) after a successful hunt. Lion and Zebra.
Killer Whale(Pred) catches up to seal (prey) and eats seal. Killer Whale and Seal.
A house cat (Pred) finds a mouse (prey). Cat and Mouse.
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.
What is a dihybrid cross?A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.
Given,
Autosomal dominant = Bb (beard), W (black coat)
Autosomal recessive = B+ (beardless ), w (white coat)
Parent = B+Bb Ww male and B+Bb Ww female
The cross between the parent is attached to the image below.
From the cross, it can be said that:
9/16 bearded, black coat1/16 beardless, white coat3/16 beardless, black coat3/16 bearded, white coatFrom the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.
Therefore, options b and e. 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.

Jaden's father is not sensitive to poison ivy. Jaden is also not sensitive to poison ivy. Jaden's lack of sensitivity to
poison ivy is which kind of trait?
environmental
acquired
learned
inherited
Answer:
Jaden's lack of sensitivity to poison ivy may be an inherited trait.
Explanation:
The poison ivy poisoning is due to the essential oils of this plant, mainly uroshiol, causing a reaction in the skin characterized by intense itching, redness and even burns with flicthenes, manifesting as an allergic reaction of varying severity.
Some people may have a low sensitivity or be insensitive to uroshiol, which does not rule out the possibility that they may become sensitive at some point in their lives.
The fact that Jaden and her father are insensitive to poison ivy venom may be an inherited trait, determined by a resistance to the allergic reaction the plant produces.
Regarding other options:
Environmental, acquired or learned traits, do not determine the resistance to certain hypersensitivity or allergy reactions, which depends on each person's immune response or sensitivity.
Answer:
inherited

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?
The trend in the corn productivity shows an increase from the year 1988 to 2008.
This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

Where do action potentials end?
The action potential terminates at the axon terminal or terminal boutons.
What do you mean by Action potential?Action potential may be defined as reversal activity in electrical potential across a plasma membrane that occurs when a cell has been activated by a stimulus.
The action potential is generated at the region of the axon hillock and propagates along the axon. Finally, they terminated at the region of the axon terminal.
Therefore, the action potential terminates at the axon terminal or terminal boutons.

A nucleotide is the building block for a specific biomolecule. It is made up of a pentose sugar, a phosphate group, and a nitrogen base. One of its functions in polymer form is to store genetic information. Which two types of biomolecules are being described in this scenario?
A . Nucleic acids and carbohydrates
B . Nucleic acids and proteins
C . Lipids and nucleic acids
D. Proteins and lipids
Answer:
D
Explanation:
The two types of biomolecules being described in the scenario would be nucleic acids and proteins.
Nucleotides are the building blocks of nucleic acids. Each nucleic acid in the form of DNA or RNA has its nucleotide sequence.
DNA is responsible for the storage of genetic information. In order for genetic information to be expressed, the information in DNA is transcribed into RNA. The genetic codes in RNA are translated to their respective amino acids and linked together by peptide bonds as proteins. Thus, genetic information are usually expressed in proteins and the RNA serves as an intermediate molecule.

Which of the following correctly describes the function of the cell wall?
The cell wall provides rigid support and protection for the cell.
The cell wall is a network of fibers inside the cell that gives the cell its shape.
The cell wall is a barrier that allows certain substances into and out of the cell.
The cell wall is a series of folded membranes that produces and distributes proteins in the cell.
The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.
What is a cell wall?A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.
The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.
The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.
The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.
Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.
The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.
Therefore, the correct option is A.

Which represents the cross between parent plants if one is heterzygous and has yellow-colored pods and the other is homzygous and has green-colored pods?
Yy ´ yy
YY ´ yy
Yy ´ Yy
yy ´ yy
Answer:
Its the first one
Yy is yellow (dominant) and heterozygous
yy is green (recessive)
with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green). There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods - Yy yy
Heterozygous genotype:The presence of two different alleles at a particular gene locus.A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.Y for yellow and y for green then the heterozygous parent would be - Yy with yellow phenotypePurebred genotype:
consists of gene pairs with genes that are the same allele typealso called the hozygousY for yellow and y for green then the hemzygous parent would be - yy with green phenotypeThus, the cross would be - Yy yy

AnswerExplanation:
The nucleolus is a region of the nucleus where ribosomal RNAs are synthesized.
Ribosomes are protein synthesis factories made from the ribosomal RNAs that are synthesized in the nucleolus and ribosomal proteins.
Sometimes, ribosomes are found free in the cytoplasm, other times they are attached to the endoplasmic reticulum, forming the rough endoplasmic reticulum. The rough endoplasmic reticulum is the site of protein synthesis for proteins that are to be secreted from the cell
