Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. cats that have coats that are a patchwork of black and orange are called tortoiseshell cats, are typically female, and have genes that code for both black fur (xo) and orange fur (xo) located on the x chromosomes. y chromosomes do not code for color in tortoiseshell cats. a female cat that has only orange fur (xoxo) is crossed with a male cat that has only black fur (xoy).

If the question is how many of the offspring will have tortoiseshell coloring (XOXo), the answer is 2 in 4.

Let's take a look at that cross:
Parents:                 XOXO       x        XoY
Offspring:       XOXo      XOY     XOXo    XOY

The offspring will look like this:
Of total 4 offspring, 2 female cats that have tortoiseshell coloring (XOXo), and 2 male cats with orange coloring.

5. Which one of the following statements does not accurately describe vibrations? A. Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate. B. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body. C. Resonance occurs as a result of sympathetic vibrations. D. A non-vibrating object can begin to vibrate as a result of forced vibrations. 8. Which of the following statements is untrue in regard to sound traveling in air? A. Sound waves in the air are transverse and consist of compressions and rarefactions of air molecules. B. The area covered by the wave front increases as the wave advances, but the energy passing through a wave front in a unit of time decreases. C. During a single vibration of the diaphragm, molecules in the air near it will also complete one vibration. D. As the distance from the Earth increases, the sound wave intensity also decreases due to the lessening density. 18. Which of the following statements incorrectly describes a scenario where the source of the sound waves and the person hearing the sound are remaining stationary? A. The frequency of the sound waves is not affected by the nature of the medium. B. The frequency of the sound waves is not altering as a result of the distance between the sound source and the listener. C. The frequency of the sound waves will change for the listener as a result of the Doppler effect. D. The frequency of the sound waves will remain the same to the listener.

Answer:

5-B

8-B

18-C

Explanation:

Hello! Let's solve this!

The answers are

5- B- Forced vibrations, such as those that occur between a fretboard and a large cabinet surface, produce a much lower sound than that produced by the original vibrating body.

8- B. The area covered by the wavefront increases as the wave progresses, but the energy that passes through a wavefront in a unit of time decreases.

18- c- The frequency of the sound waves will change for the listener as a result of the Doppler effect.

The Doppler effect is a change in frequency due to a change in the source.

Answer:

A combination of sperm and other reproductive fluids.

Explanation:

  • Semen is a fluid released from the penis during ejaculation that consists of the sperms along with the fluid secretion of the seminal vesicles, bulbourethral glands, and the prostate gland.
  • The fluids secreted by the seminal vesicles and prostates glands are essential to maintain the motility of the sperm as well as maintain their viability.
  • Some of the components of the semen besides sperm are sucrose, citrate, vitamins, acid phosphatase, fibrinolysin, galactose, mucus, etc.

QUESTION POSTED AT 25/01/2020 - 03:00 PM

There is a population of Drosophila flies in a small fruit shop Due to sudden mutation, the eye color of some of the flies changes from red to white Red (represented by R) is the dominant gene, and white (represented by r) is a recessive gene Due to this, the gene frequency of allele r changes from 0.38 to 0.40. What will be the new genotype frequencies in that population? ( p + q = 1, p2 + 2pq + q2 = 1) A.) p2 = 0.36, 2pq = 0.48, q2 = 0.16 B.) p2 = 0.32, 2pq = 0.23, q2 = 0.45 C.) p2 = 0.25, 2pq = 0.36, q2 = 0.39

The answer is A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.



Let's first distinguish alleles frequencies from genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.



The gene frequency of allele r changes from 0.38 to 0.40, thus:
q = 0.40


Now, we will implement this in the following equation:
p + q = 1

If q = 0.40, then:
p + 0.40 = 1
⇒ p = 1 - 0.40
⇒ p = 0.60



Now, the frequencies of both alleles are know and it is easy to calculate the genotype frequencies:
- the frequency of RR genotype: p² = 0.60² = 0.36

- the frequency of Rr genotype: 2pq = 2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² = 0.16



Therefore, the new genotype frequencies in that population are p2 = 0.36, 2pq = 0.48, q2 = 0.16.

Which part of the eye acts as a secondary area of refraction to "fine tune" the focus? the iris the cornea the lens the retina

Answer:

The lens

Explanation:

Lens of human eye have ability to change its shape and thereby changing the focus for near or far vision. The ability of lens to fine tune the focus by change in its shape is called as accommodation and is done with help of ciliary muscles. Contraction of ciliary muscles makes the lens more round to focus the closely located objects. Relaxed ciliary muscles makes the lens to assume flat or ovoid shape to focus on distantly placed objects.

A student is examining leaf cells. Which organelle is most likely to be missing from the cells? A.a cell wall B.chloroplasts C.lysosomes D.a cell membrane

Answer: C.lysosomes

Explanation: A leaf cell is typically comprises of cell wall, a cell membrane and chloroplasts. The leaf is the chief photosynthesizing organ of the plant system. The chloroplast helps in trapping the light energy from sun which is used along with the reactants like water and carbon dioxide to produce  carbohydrate as food and oxygen. Lysosomes are organelles which are not found in the leaf cells because it's function is to digest the cellular wastes like ions, proteins and other metabolites. Leaves are the main food synthesizing organs of the plant no wastes digestion occur in the leaves.

Exploring the south american rainforest, a scientist discovers a mysterious organism and brings it back to the lab for further study. what cell characteristics should the scientist examine to tell whether the organism is an animal or plant? why?

Answer:

In the given case, the scientist should first look for a cell wall as only cells of the plants possess a cell wall. After that he or she should examine for chloroplasts as animal cells do not possess chloroplasts. And finally, he or she should look for the vacuole, that is, if the vacuole is of small size, then it is most probably be an animal cell, however, if it is large then it is most probably a plant cell.
