In flies, red eye color (Xa) is a sex-linked recessive trait. Black eyes (XA) are the normal colored eyes for flies. What are the chances
that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10

Answers

Answer 1

Answer:

The correct answer is -

a. a red-eye male as their next offspring? = 25%

b. a black eye female as their next offspring? = 25%

Explanation:

The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.

So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:

        XA          Y

Xa     XaXA    XaY

XA   XAXA     XAY

On the basis of red eye male would be XaY = 1/4 = 25%

and the black eye female would be XAXA  = 1/4 = 25%

If mutated DNA sequence #1 occurred in a single reproductive cell of a fish that was later fertilized to become an offspring, how might it impact the organism

Answers

Answer:

Offspring will have some sort of genetic variation from parent (may be positive or negative or no effect,  based on the mutation type)

Explanation:

The reproductive cells pass on the traits from the parents to the offspring.

An organism that is mutated at a single DNA location in a reproductive cell, then that mutation will be passed on to the offspring.

Based on fact, that mutation will lead to some kind of effect in any trait, hence the same trait will be effected because of mutation in the offspring as well

It can also be said that offspring will have some sort of variation from parent (may be positive or negative or no effect,  based on the mutation type)

B. Planting trees and other plants to attract native species
C. Creating laws to prohibit fishing from local streams
D. Removing non-native species from the environment.​

Answers

Answer:

A.  Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.

Explanation:

Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).

Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.

Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.

This leaves A as the answer.

When a lake freezes over. How does the energy content of the lake change?

Answers

Answer:

Explanation:The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies

Question: How do ocean currents affect the coastal regions of S.America at 20 degrees south latitudeAnswer: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal regionQuestion: When a lake freezes over. How does the energy content of the lake change? Answer: Liquid water has more energy than frozen water. When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released(WATER IS THE LAKE)Bonus: I know that during melting, there is no temperature change as the heat energy is used to do work against potential bond energy but why doesn't temperature change when freezing? Freezing is the opposite process of melting. If the temperature does not increase as the ice melts, the temperature will not decrease as water freezes. Melting and freezing are entropy changes. Entropy measure the amount of disorder in a system. A system, like ice, which has less freedom of motion, has less disorder. A system, like liquid water, which has more freedom of motion, has more disorder. So water has more entropy than ice. Ice is a very ordered arrangement of H2O molecules in a crystalline form. As heat energy is added to ice, the energy is used the break the bonds between the H2O molecules in the ice crystals. So, the temperature remains constant. You might say that the energy that is added to the ice is used to increase the entropy of the system, instead of increasing the temperature of the system.-TAY brainly please

A galaxy has less mass than a moon and more mass than a planet.

False

Answers

Answer:

False, major false. A galaxy is a small portion of the entire universe... it contains plants, stars, asteroids, moons are insignificant compared to it. Also, pretty much all moons are larger than planets so that wouldn't even make sense.

Answer:

FALSE

Explanation:

First off a galaxy is one of the largest things in space, besides things like galaxy clusters.

Second all planets have more mass than the moon. Since planets have more mass than a moon, it is impossible to have less mass than a moon but more than a planet.

Finally, a galaxy is made up of millions of planets and moons. So it does not make any sense nor is it even possible.

Describe the functions and organization of tissue systems in a seed plant.

Answers

Answer:

tissues is the protect outer covering of plants

Explanation:

Plants consist of many different types of cells that are organized into aggregates called tissues. Tissues are derived from specialized groups of dividing cells called meristems. Meristems are the source of cells and tissues and therefore they are not strictly speaking tissues themselves

Plants are multicellular eukaryotes with organized tissue and specialized organs with specific tasks.

What are the functions and organization of the tissue system in a seed plant?Plants are multicellular eukaryotes, and their tissue systems are made up of many cell types that serve distinct purposes. Meristematic tissue and permanent (or non-meristematic) tissue are the two main forms of plant tissue systems. Meristems, which are areas of plants that experience continuous cell division and expansion, are where the meristematic tissue's cells may be located. Meristematic tissue cells continue to divide and support plant growth despite being either undifferentiated or incompletely differentiated. Permanent tissue is made up of dormant plant cells, which are no longer actively dividing.Secondary tissues can be simple (made up of similar cell types) or complex (composed of different cell types). Dermal tissue is a simple tissue that covers the plant's exterior and regulates gas exchange. One example of a complex tissue is vascular tissue, which is composed of the specialized conducting tissues xylem and phloem.
