The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem
Explanation:
This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).
According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:
HH, Hh, Hh, and hh
3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).
Answer:
75% hairy stems; 25% hairless stems

Imagine that you are standing in a field and you see a group of butterflies. You notice an individual butterfly that looks significantly different from the others in the population. Its difference allows the butterfly to escape predation more efficiently than the other butterflies. How might this trait have arisen in the individual

Answer:
Explanation:
Mutation is a sudden change in the genome of an organism that is heritable.
Mutation occur due to a spontaneous change in the sequence of a gene, it can occur during DNA (deoxyribonucliec acid) replication, mitosis, meiosis. Some mutation are beneficial, some are detrimental while some could be deleterious. Mutation is a rare occurrence usually one in several hundreds or thousand
The unique traits that was reveal in the bird is due to mutation, it is beneficial because it kept it away from predation it is a rare case.
Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.
Answers
Answer:
81/256
Explanation:
By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.
Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

Answers
Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems.

Transposable elements can induce mutations by all of the following mechanisms EXCEPT: disrupting a gene when inserted into it. facilitating recombination between transposons, producing chromosomal mutations. producing double-stranded breaks during excision, leading to chromosomal mutations. Activating genes with their own promoter, dysregulating them.
Answers
Answer:
Activating genes with their own promoter, dysregulating them.
Explanation:
Transposable Elements (TEs), also known as transposons, mobile elements or jumping genes, are genetic sequences able to move within a host genome by a mechanism called 'transposition'. As a result of their transposition, TEs may cause diverse genetic alterations and disrupt host gene expression at the integration site. Some of the most common deleterious effects induced by TE transposition include, among others, insertional mutagenesis, duplicated sequences, chromosome translocations, etc. Moreover, although it has been shown that some types of TEs contain transcription factor binding sites (as well as cis-regulatory motifs), they don't have promoter sequences that activate host gene expression upon TE transposition.

Answers
Answer:
C. to reproduce
Explanation:
All living cells undergo division to produce more identical or different cells. The major types of cell divisions that cells undergo are; mitosis and meiosis. Mitosis results in two identical daughter cells being produced from a single cell while meiosis results in four daughter cells being produced.
The primary aim of any form of cell division is to REPRODUCE or PROCREATE the number of cells. For example, mitosis produces two (2) cells from 1 and so on....

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis
Answers
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

Carbon-14 is a radioactive isotope of carbon that has a half-life of about 5,730
years. You have discovered a fossil and want to know how old the fossil is. You count
the parent and daughter atoms and calculate that you have about 6.25% of the
parent atom (carbon-14) left. How old is the fossil? (Provide units (years) for your
final answer. You must show your work.
2 points for showing work
1 point for final answer with units
Answers
Answer:
22,920 years
Explanation:
When the fossil first started to decay, it must have had 100% of its parent carbon-14 atoms. Every 5,730 years, that amount gets cut in half. Let's travel back a ways, to the very beginning, 0 years into the decay. We'll keep track of the time elapsed, the number of half-lifes, and the percent of carbon-14 remaining:
0 years (0 half-lives) - 100%5,730 years (1 half-life) - 50%11,460 years (2 half-lives) - 25%17,190 years (3 half-lives) - 11.5%22,920 years (4 half-lives) - 6.25%That last one represents our situation, so the fossil is 22,920 years old.
What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.
Answers
Answer and Explanation:
An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface. These rings can be cut into various sizes. An oil ring has an axial.
