A student in genetics class is studying the inheritance patterns in fruit flies. He is looking at the traits for wing length, long versus short, and colorbrown versus gray. Using a dihybrid cross of two flies that were heterozygous for long wings and brown color. Long wings and Gray are dominant. How many offspring will have long wings and brown color?

Answers

Answer 1

Answer:

LLgg, Llgg , two out of 16

Explanation:

Given,

Dominant - Long wings and Gray color

Recessive - Short wings and Brown color

Let the allele for long wings be "L" and the allele for short wings be "l".

Let the allele for brown color be "g" and allele for gray color be "G"

Genotype of parents

LlGg

Gametes of the parent

LG, Lg, lG, lg

Dihybrid cross is between LlGg and LlGg

The offspring produces will be as follows -

LG        Lg         lG         lg

LG LLGG LLGg LlGG LlGg

Lg LLGg LLgg LlGg Llgg

lG LlGG LlGg llGG         llGg

lg LlGg Llgg         llGg         llgg

Offspring with long wings and brown color – LLgg, Llgg , two out of 16

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.

Answers

Answer:

B

Explanation:

the longest phase in the cell division is interphase because the DNA replication occurs in this phase

As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.

What is cell cycle?

The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.

A cell cycle is the series of events that takes place in a cell as it grows as well as divides.

A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.

Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.

Thus, the correct option is D.

Number 1 is C
And im not sure about the rest :(

Storing hormones, smooth and cardiac muscles are the correct answers.

Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.

Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%

Answers

Answer:

b. The chance of an offspring having white eyes is 50%

Explanation:

So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.

The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).

If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.

Now, let's look at the choices:

A.: The chance of an offspring having red eyes is not 75%; it is 50%.

B.: The chance of an offspring having white eyes is 50%!!!

C.: The chance that a male offspring will have white eyes is 50%, not 0%.

D.: The chance that a male offspring will have white eyes is 50%, not 100%.

How does light behave around opaque, transparent and translucent
Need answer ASAP please
NO copy and paste thanks!

Answers

Answer:

Transparent objects allow all the light to pass through them. Opaque ones allow no light to pass through. Translucent allows light to go through but the area in it is no visible to determine the object

Explanation:

Think of Transparent as a window u can see straight through it is clear.Think of Translucent as a window with cold fog on the window light can come through it but you can't see whats outside.Think of Opaque as a black chalkboard light reflect on it but light cannot go through it

Answer:

Transparent: light will completely pass through and is very visible through the transparent object. For example, sunlight through a window

Translucent: some light will pass through, will be somewhat visible. For example, if you put a flashlight or your phones flash against a piece of paper, the light will pass through but not as much as light through a window

Opaque: you will not be able to see light through an opaque object, for example, putting a flashlight against a large book or a rock. No light will pass through the object.

What percent of the offspring will be red, if we cross two pink tulips?




75 %

Answers

Answer: 50

Explanation:you are combining two pink to the possibility of the tulips being red will be 50 50

It is a case of incomplete dominance. 25% of the offspring will be red. Therefore, option C is correct.

What is incomplete dominance?

When two heterozygous alleles in a gene interact with each other, their traits are expressed partially, because they both are not dominant on each other. This type of dominance is called incomplete dominance.

It is not necessary to do a test to identify the heterozygous in incomplete dominance. The phenotype and genotype ratio is the same in this dominance. Incomplete dominance is different from co-dominance.

When two heterozygous pink tulips (Rr) cross, then 25% red (RR), 50% pink (Rr), and 25% white (rr) tulip flowers are produced. The phenotype and genotype ratio will be 1:2:1. Therefore, option C is correct.

Explain how conservation efforts have positively impacted ecosystems.​

Answers

Many ecosystems have been improved. When you practice conservation, it can have various positive effects, including bringing back endangered species. The ecosystems are being protected, and they have the opportunity to flourish.

Conservation efforts have played a crucial role in mitigating the loss of biodiversity, protecting ecosystems, and promoting sustainable development.

Conservation efforts have had several positive impacts on ecosystems. Firstly, the establishment of protected areas and conservation reserves has helped preserve and restore natural habitats, providing a safe haven for wildlife and plant species. This has led to the recovery of many endangered and threatened species, contributing to the overall biodiversity and ecological balance.

Conservation efforts also promote sustainable resource management practices. By implementing regulations and guidelines for fishing, hunting, logging, and other human activities, ecosystems are protected from overexploitation. This helps maintain healthy populations of species, prevents habitat degradation, and ensures the long-term availability of resources.
